• Touchpad has completely stopped working

  Hey, my touchpad completely stopped working. I tried to download the driver and restart and the stuff, but nothing seems to work. There was formerly an icon for it down to the right on the toolbar, but that's even more here, it's like the software so that it just doesn't even exist anymore.

  Can anyone suggest a solution please?
  Thank you

  Hello!

  You can disable and enable the touchpad with FN + F9. Select this check box, because maybe it s disabled.

  Have you tested an external mouse? You have the same problem with it?

• iMac 2010 slower that a turtle stuck in the mud after having swallowed the glue

  Since upgrading to OS X El Capitan (from factory 10.6 Snow Leopard), my poor iMac have been incredibly slow. To the point where eventually it still would not start.

  Since I have everything of importance on an external hard drive, I just went ahead and started from the install disc, go for a clean install.

  It took several attempts for the system to boot from disk (starting with C) before finally reading the disk and load the language selection screen. It took almost three days to go through the own installation process. And I mean everyday! Each step takes several hours. I had two beds in this horrible process!

  Finally, I registered and through on the desktop. How he was always slow that I felt a stop down was in order. I left for the day. I just go back and press the power button and watched the gray screen with spinner logo and daisy apple during the last 30 minutes.

  Does anyone have any ideas why this might be. I appreciate, it's a six year old machine, but my experience with Apple computers over the past 15 years has been such that I don't expect to die after only six years.

  My guess is that it is a problem of hard disk of a certain type? But if someone could point me in the right direction, I'd be happy.

  Thanks in advance.

  It should of course not take three days to install OS X, even if the Mac is a former model.  My 2011 mini ran Mac OS X El Capitan (and currently macOS tracks Sierra) very well, and it has the lowest overall performance compared to an iMac of 2010.

  It took several attempts for the system to boot from the disk (starting with C)

  El Capitan is not installed on a drive, if you are saying you reinstalled Snow Leopard first?  That is what is running slowly or not at all?

  Here are a few things to try...

  Because you have previously installed El Capitan, depending on how you launched the "clean install", its partition Recovery HD hidden is maybe still there internal hard disk.  Press command-R to start.  Here's more information

  On OS X Recovery - Apple Support

  Alternatively, you can start with the Option key to display the Boot Manager screen, which gives you the choice of available startup disk.  See if Recovery HD is an available choice.

  If you can start ("Recovery") as described in the linked document, run disk utility and Erase the internal disk volume.  Then reinstall OS X.  This gives you El Capitan directly, instead of first Snow Leopard install.

  If the internal drive is actually defective, and you have an external USB drive that can be erased, you can (temporarily) install the OS on this external drive.  You should unplug your drive with the user data (if not already done), to avoid accidentally erasing.  You can do this installation of the recovery screen (if you are able to start up the Recovery HD).  If not, you need to install Snow Leopard, first (if everything goes much faster than three days).  Whatever it is, run disk utility (from the menu bar if you have reinstalled Snow Leopard).  Select the external target drive in utility box disc and Erase completely.  Then install OS X on this external drive.

  After installation and reboot, you can reconnect to another external drive with user data and use this way until you replace the internal drive.  If you have installed Snow Leopard, he move to El Capitan, using the normal procedure.

• My Mac is hacked! Encryption help please!

  My Mac Pro is hacked, and this is confirmed by the engineers. Because the Mail app and even online ISP mail did not work if good PSI hunted hackers. I found files fragmented on 240 and 480 GB Intel SSD drives into the slots of the T2 drive: files named "sparse disk image...". ' and ' package of rare records...' appeared in the root of the readers. I could easily remove them. But I never put there. At the same time, Apple Mail app kept resetting ports 993/587 (course) to ports 143/25 (very insecure). Post font size 23pt appeared, ads corrupted font, file extensions book would not appear or would disappear, etc, etc, etc. The internet connection was bad too, so I called my ISP. ISP found twelve 12 computers in windows using various applications on my system. None of the computers used found languages where I live. Pirates. I also have an airport with a cap of 2 TB, and it is probably also diverted. Nothing in my system is encrypted. I just use firewall, even if it does not get somehow.

  Advise main suggested Apple should I encrypt my records. But these fragmented files were already there. Which indicates that someone somewhere on Earth was already encrypt files on my system. The adviser said fragmented files are a pretty good indication that its time to get more proactive. If my plan is to use disk utility to wipe my internal drive OS, OS X Extended (journaled encrypted). Then install OS X on the disc encrypted EAS - 256 bit.

  For those who have experience of encryption Mac

  1.) encrypt and install OS X on the encrypted drive wise?

  2.) how to clear all present airport Time Capsule content, encrypt Time Capsule and use it with my encrypted system?

  3.) how to encrypt external disks and use them with encrypted Time Capsule and encrypted internal drive?

  (4.) how to manually copy files from encrypted disks (mainly SSD external drives) of other backup disks which are normally cold (disconnected) for monthly backups of cold. "

  5.) monthly cold copies remain unencrypted?

  I worked with Mac since the 1980s. You can ignore it, but here are my thoughts: encrypt just the disk won't do much. I am surprised that the Apple engineer suggested this. If your Mac is compromised (depending on the ISP see Windows for access to the you that seems reasonable) the things MOST IMPORTANT to do is eliminate the hack code. If you encrypt the disk with the hack still there it is more likely will always have access to the data. Before going that all keep in mind that you probably allowed the hack in installation of the software on the web or by opening an attachment with the hack. So everything you try to remember what helped you ensure that you wouldn't do it again.

  You should consult your application package to see if there is something that you don't recognize or recently installed before the problem and remove before you try anything because it is possible the cut is integrated into an application. Remember that almost all hacks are hidden in the system and not easily seen so you probably won't find it. My approach is to install a charge/clean OS X, then copy your applications and your data.

  There are many approaches to this problem, but here's what I think, this is the simplest approach IF you have access to a second mac AND hack code doesn't do not part of one of your applications.  You said not what type of Mac you have or the system or if you have access to other Macs. My proposal would be based on that. Since you are in a jam here are a few options:

  If you have more than one Mac and an external hard drive:

  1. start the mac infected in target mode: restart and as soon as it chimes hold "T".

  2 connect the Mac, because I know you can't tell how. You can google it.

  3 format an external hard drive to use as a target of installation for El Capitan.

  4 download and install El Capitan on the Apple App store and install it on the external drive.

  5. after starting upwards, when asked if you want to copy applications and data to another Mac say Yes and let it copy the applications and data from the infected Mac internal drive.

  6. Once installation is complete it should start from the outside, test your system for ensure that everything works, you have all your dataand see if the problems are eliminated.

  7. If it's good, when it is started from the outside:

  8 download Super Duper or carbon copy. (I use SD).

  9. use disk utility in the folder utilities to clear the internal drive.

  10. copy your external drive to the internal drive, it will be deleted.

  11. when the copy is complete, stop the Mac and disconnect the external hard drive.

  12. start the Mac, go to Preferences-> floppy boot, then selected your internal drive system, she might want to restart. This step is optional, but if the boots aren't made can be more slow that the Mac external drive first.

  If you have access to an external hard drive:

  Remember that although it would probably be fine, there is a slight possibility that this can infect a connected drive, this is the case, you must use multiple macs above approach. But it's something you can try if you don't have a second mac.

  * Skip steps 1-2 above and do the rest on the infected mac.

  If you do not have an external drive, you can use a large USB but it will be much slower. Good luck, I hope that others will come to the top with options. But it's what I would do.

• Moving iTunes, but leaving some files.

  I am moving from one laptop to another and have to move my instance of iTunes.

  I have a lot of older podcasts, I saved, and I want to keep them. Unfortunately I don't have much disk space on the new machine that I had on the old, so I'll have to cut them on the new machine.

  What is the best way to solve this problem?

  I do more iTunes files, and then delete the individual podcasts that I don't want to keep it on the new machine?

  Is it possible to load iTunes, registration and it has NOT automatically download the historical files of the iTunes server?

  See how to backup your iTunes for Windows with SyncToy library. You can keep a complete copy of the library on the external hard drive, but remove some content (and exclude from synchronization) some files to reduce the size of the online library. Alternatively, you can run the entire library from the outside and use another for backup.

• Mac Pro 5.1 mid 2012 closing

  My 40 odd years of owning Macs, which dates back to the classic Mac with a screen 13-inch black and white, I have never seen this. All started about 2 weeks ago, when I got home from work and my Mac had stopped. I thought it could have been an electricity failure, so I just rebooted. No problem. But then it started to happen more frequently. A few times it will turn off then I was in the middle of something, like getting emails or surf the web. Jumping to come up to our days... now, when I have the power to get the bong, the Apple gray and gray progress bar, but it stops almost exactly when the progress bar comes in half way through! Last night he did about 10 times in a row. Today, same thing. In addition, when you turn on using the modifier keys, as the PRAM reset or start in safe mode, or hold CMD and D to launch a test of hardware, it stops before the same progress bar appears on the screen. Here's what I did then tried farhati starting from different hard drives, including an external... tried the boot in another Bay... deleted disk cards RAM and only used a 16 GB to start... exchanged slots of RAM... disconnected all devices, including my monitor, keyboard, and mouse... even removed the video card ATI Radeon completely from the machine... removed the optical drive... removed the processor tray to clean and inspect. Cleaned all fans and assured they were working. And that's all. One thing I noticed... sometimes red located next to each RAM slot is lit on both of them. They are each on the two slots that are closest to the processor. In these slots, I have a 2 GB card each. If I take them off, the LED turn off, but it does not help the problem. BTW, I have two 16 GB of RAM cards in the two front slots. I think my card is bad. I'm puzzled!

  spontaneous, uncontrolled stop is most often caused by overheating, which can be aggravated by the accumulation of dust bunnies.

  It stops almost exactly when the progress bar comes in half way through!

  start up your Mac, the dark Apple is loaded with the first "blob" of software by a known location on the disk. Later, when the file system is initialized, the boot drive is mounted as a Volume of macOS. If it cannot be mounted, a repair disk function is started. The progress bar lingers on the screen while the process continues.

  At the end of the repair, there are two possibilities:

  (a) the startup disk can be mounted. Start continues.

  (b) the startup disk cannot be mounted. Since there is no way to make further progress, you Mac stops.

  Your solution: repair the boot drive. If this is not possible, to obtain a replacement disk and installs a new MacOS top. That gets you a job entirely Mac so that you can recover, restore or repair you need.

  Your Mac can boot from a drive, internal or external. The best way forward is to ADD a replacement disk, so that when Mac OS is installed, you can work with the old drive as well.

• My Macbook Pro does'nt connect after update to 10.11.6

  Hi all.

  After update from my Macbook Pro to 10.11.6 he starts, but after entering my password, then pressing enter shows the loading animation and it is.  I let him go lastnight believe he worked at something after the update, but this morning, nothing...

  An advise, please.

  Kind regards

  Fabio

  Please take each of these steps that you have not already tried it. Some of them are not applicable to your model or your situation. Stop when the problem is resolved.

  To restart a computer is not responding, press and hold the power button for a few seconds until the unit turns off, then release, wait a few seconds and press again briefly.

  Step 1

  The first step to respond to a startup failure is to secure data. If you want to keep the contents of the boot drive and you have not already at least a current backup, you should try to back up now, before we do anything else. It may or may not be possible. If you don't care the data changed since the last backup, you can skip this step.

  There are several ways to back up a Mac that is unable to boot. You need an external hard drive to store backup data.

  a. starting the partition recovery or an hour Local Machine backup volume (button option key at startup). When the OS X Utilities appears, launch disk utility and follow the instructions in this article to support. You'll be 'restoration' the boot on the backup volume volume.

  If you use 2 FileVault, you must first unlock the boot volume. Select its icon ("Macintosh HD", unless you have given it a different name.) It will be nested under another icon of the disc. Select open in the file menu. When you are prompted, enter your login password.

  (b) If step 1 fails due to disk errors, and no other Mac is available, then you may be able to save some of your files by copying them in the Finder. If you already have an external hard drive with OS X installed, the start of it. Otherwise, if you have access to the Internet, follow the instructions on this page to prepare the external hard drive and install OS X on it. You will use the installation program of recovery, rather than download it from the App Store.

  c. If you have access to a Mac, and it work and have both the non-working Mac FireWire ports or stroke, start the Mac non-working in target disk mode. Work Mac to copy the data to another drive. This technique will not work with USB, Ethernet, Wi - Fi or Bluetooth.

  d. If the internal drive of the non-working Mac is replaceable by the user, remove it and climb into a docking station that is pregnant or an external drive. Use another Mac to copy the data.

  Step 2

  If you have booted from an external drive, make sure that the internal boot volume is selected in the pane of the system preferences Startup disk.

  Start in safe mode. Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. If you do not see the words "Safe Boot" in the start screen, you did not start in safe mode. Ask for additional instructions.

  Safe mode is much slower to boot and run as normal, and some things don't work at all, including the networks without wire on some Macs.

  The login screen is displayed even if you normally connect automatically. You must know the password for the connection to connect. If you have forgotten the password, you will have to reset it before you begin.

  If the startup progress bar gets stuck for more than a few minutes, or the system stops automatically when the progress bar appears, the boot volume is corrupted and the player is probably defective. In this case, go to step 9. If you have another problem with the player, replace it immediately.

  If you can start and log in in safe mode, empty the trash and then open the window of info on the boot volume ("Macintosh HD", unless you have given it a different name.) Make sure you have at least 9 GB of space available, as shown in the window. If you do not, copy as many files as necessary on another volume (not another folder on the same volume) and delete the originals. Deletion is not complete until you empty the trash again. This, until the space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)

  If the boot process hangs again, the problem is probably caused by third-party software you have installed. Ask for additional instructions.

  Step 3

  If the startup process stops at a gray screen together with a mobile cursor, then the logon dialog box may be active but not visible because of a bug. You may be able to connect by using the arrow keys or the cursor to select the password field and type your password as usual.

  Step 4

  Case of failure of step 3, the boot volume can be complete. If you saw previously implemented guard space drive is low, it is certainly the case. You might be able to start in safe mode , even if you cannot boot normally. Otherwise, boot from an external hard drive, or well technology for step 1b, 1 c or 1 d allows to mount the internal drive and delete some files. According to the documentation from Apple, you need at least 9 GB of free space on the boot (as shown in the Infolog) for normal operation volume.

  Step 5

  If a Mac desktop (without the built-in keyboard) crashes on a gray screen together with a mobile cursor, the keyboard may not be recognized. Hold down the button on the side of a wireless Apple keyboard to make it discoverable. If need be, replace or recharge the batteries. If you use a USB keyboard connected to a hub, connect it to a built-in port.

  Step 6

  Sometimes, a startup failure can be solved by resetting the NVRAM.

  Step 7

  If there is an integrated optical drive, a disk may be stuck in there. Follow these instructions to remove it.

  Step 8

  Press and hold the power button until the unit turns off. Disconnect all devices wired except those needed to start and remove all aftermarket expansion cards. Use another keyboard and/or mouse, if these devices are wired. If you can start now, one of the devices that you disconnected, or a combination of both, the origin of the problem. Discover that it is a process of elimination.

  Step 9

  Launch the utility disk in recovery mode (see step 1). Select the boot volume, and then run the repair disk. If problems are found, repeat until that clear. If disk utility reports that the volume is not repairable, the drive is defective and must be replaced. You can choose to tolerate such malfunction in the reader's life. In this case, delete the volume and restore it from a backup. If the same thing happens again, replace the drive immediately.

  It is one of the rare situations where you must also run repair permissions, ignoring the erroneous warnings, that it can produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.

  Step 10

  If the boot device is an aftermarket SSD, it may have an update and/or a forced "garbage collection". Instructions how to do this with a Crucial SSD of brand have been posted here. Some of these instructions may apply to other brands of SSDS, but you should check with the technical support of the provider.

  Step 11

  Reinstall the OS. If the Mac has upgraded an earlier version of Mac OS X, you need the Apple ID and password used to upgrade.

  Step 12

  Do as in step 11, but this time clear the disk utility boot volume before installing. The system should automatically restart in The Migration Wizard. Follow the prompts to transfer data from one Time Machine or another backup.

  Step 13

  This step applies only to models that have a battery logic-board ("PRAM"): all of the Mac Pro, MacBook with a removable main battery and a few others (models not updated). A flat battery logic-board may cause a boot failure. In general the failure will be preceded by the loss of the system and boot disk clock settings. Refer to the user manual for replacement instructions. You may need to take the machine to a provider of services to have to replace the battery.

  Step 14

  If you get this far, you probably deal a hardware failure. An appointment of 'Genius' to an Apple Store, or select another authorized service provider.

• After update, can't login, just gear turns

  After that I updated to 10.11.6, I cannot connect to my iMac. The login screen accepts my password, but the gear/turn icon just wirhout everything that happens. Then I rebooted into recovery mode and reinstalled bit El Capitan, the problem persists. I am at a loss total and rather hopeless.  Help, please.

Hold down the button on the side of a wireless Apple keyboard to make it discoverable. If need be, replace or recharge the batteries. If you use a USB keyboard connected to a hub, connect it to a built-in port.

  Step 6

  Sometimes, a startup failure can be solved by resetting the NVRAM.

  Step 7

  If there is an integrated optical drive, a disk may be stuck in there. Follow these instructions to remove it.

  Step 8

  Press and hold the power button until the unit turns off. Disconnect all devices wired except those needed to start and remove all aftermarket expansion cards. Use another keyboard and/or mouse, if these devices are wired. If you can start now, one of the devices that you disconnected, or a combination of both, the origin of the problem. Discover that it is a process of elimination.

  Step 9

  Launch the utility disk in recovery mode (see step 1). Select the boot volume, and then run the repair disk. If problems are found, repeat until that clear. If disk utility reports that the volume is not repairable, the drive is defective and must be replaced. You can choose to tolerate such malfunction in the reader's life. In this case, delete the volume and restore it from a backup. If the same thing happens again, replace the drive immediately.

  It is one of the rare situations where you must also run repair permissions, ignoring the erroneous warnings, that it can produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.

  Step 10

  If the boot device is an aftermarket SSD, it may have an update and/or a forced "garbage collection". Instructions how to do this with a Crucial SSD of brand have been posted here. Some of these instructions may apply to other brands of SSDS, but you should check with the technical support of the provider.

  Step 11

  Reinstall the OS. If the Mac has upgraded an earlier version of Mac OS X, you need the Apple ID and password used to upgrade.

  Step 12

  Do as in step 11, but this time clear the disk utility boot volume before installing. The system should automatically restart in The Migration Wizard. Follow the prompts to transfer data from one Time Machine or another backup.

  Step 13

  This step applies only to models that have a battery logic-board ("PRAM"): all of the Mac Pro, MacBook with a removable main battery and a few others (models not updated). A flat battery logic-board may cause a boot failure. In general the failure will be preceded by the loss of the system and boot disk clock settings. Refer to the user manual for replacement instructions. You may need to take the machine to a provider of services to have to replace the battery.

  Step 14

  If you get this far, you probably deal a hardware failure. An appointment of 'Genius' to an Apple Store, or select another authorized service provider.

• tried everything to no problems printing - no luck

  Hi, since I upgraded to El Capitan my macbook air was not able to see the printers on my network wifi or connected via USB. I fixed it once (I kept trying things and eventually they both show) but they disappeared a few days later and today I tried previously tried everything and nothing works. Here is what I tried it - is there anything else anyone can think? I would like to downgrade to Yosemite, but Setup was removed from the Apple store so it's not an option more.

  (1) I checked to see if the printers were on and connected to the wifi network.

  (2) I have reset the printing system

  (3) I renamed the printer folder in library old printer and reinstalled the printer drivers for printers

  (4) I used the terminal window to correct permissions

  (5) I downloaded the latest drivers from gutenprint for mac

  (6) I installed a completely clean picture of El Capitan After erasing my drive

  (7) I have restored a previous image that I created just after I solved the problem of the printer

  None of these things worked. When I click on the plus sign on the printers and scanners to add a new printer, there is no printer available to add. Even when I connect one of the printers with a USB port, it is not seen by the mac.

  I really don't know what to do at this point. It is not a printer problem, because these are two different manufacturers - it's certainly a problem with the mac. I am able to use google cloud print with printers (if they are indeed on the wifi network).

  Any advice would be appreciated.

  I installed a completely clean picture of El Capitan After erasing my drive

  And then I tried adding printers without installing other software, or whatever it is restoring a backup? Are you sure of that?

  Is what kind of printer?
