• Cannot connect to the macbook pro guard icloud password request which I changed it too many times I don't remember and it still does not

  Can not connect to macbook pro, that keeps asking for password to icloud I have reset too many times I do not remember. Reinstalled operating system still does not work. Think to screw up the laptop and get back to a Windows machine. Not impressed with Apple.

  To connect to your computer, you must enter your computer in password journal, not your Apple ID.

  Otherwise, provide more details on exactly what is happening on.

• MacBook Pro from my purse, blazing hot shot.

  Dear Apple friends,

  Is someone can you please tell me why my MacBook Pro guard wake itself up in my bag? I have "wake for BT devices" unchecked.

  Here's a copy of what my "reasons wake" is...

  

  I plugged it in at about 15:10 after pulling it out of my bag, it was boiling hot. I close the lid, it is supposed to go to sleep but it is clearly not.

  Thank you, in advance.

  Why not stop instead of sleep it.   If its boiling hot and still works without stopping the incredible.

• MacBook Pro disconnects Internet randomly

  Hi friends,

  I have a Macbook Pro of the retina (11.3 end 2013) gives me a headache with WiFi at home.

  In my Studio, where I have another internet provider, it works well, but in my house is disconnect randomly.

  I have an apple TV, two ipads, an iphone and a macbook, all very well without any problem of internet work.

  I rechecked the domains DNS and TCP/IP to be exactly like the other MacBooks, which works very well. The only number that is different is the last of the IPv4, which I think is great because it shows the different device IP address. This number changes whenever I am connected, according to the other connection of both devices. Whenever I tried the Configurator wizard get correct for a few minutes, and then internet connection disappears again.

  So, what can cause this problem? Why I have a solid connection in my studio and not at home? Why the other macbook is great if I have the same values TCP/IP and DNS? The internet provider, I called and they told me that they work with IP and dynamic DNS, so it's good to let them 'automatic', which is what I use.

  Any help appreciated.

  Please do the following and after each test to see if the problem is resolved - if yes, then you can omit the following steps - I tried to list them in ascending order of the effort at least on a Mac and / or an iDevice

  1. Check if the problem is related to a single device and if other devices connect normally-
  2. If the answer 1 is 'yes' - try to connect the device assigned to somewhere else if possible - coffee or the University
  3. Settings - WiFi - < network name > - Click on forget network - do a restart forced according to 3 and then add again the network
  4. If home - reboot the router by unplugging it for 60 seconds (power) and the plug and reconnect - obviously, this step can be done in a public place like a cafe or airport or University. While you're there - make sure your router is working on the latest firmware (check manufacturer's website)
  5. Hold the pointer over the WiFi icon - click Option and then press the icon - run diagnostics of WiFi
  6. If no problem - let it run in the background and see if it detects something
  7. While you're there - make a snapshot of the gray matter and post it after deletion of personal information
  8. An appointment of 'Genius' to an Apple Store, or select another authorized service provider.

• Accidentally disconnected Macbook Pro on the first charge

  I've been advised to load my new Macbook Pro 13 "8 hours for the first charge. I plugged it in for about 5 hours and the charger got accidentally disconnected from my mac but I've not noticed until 3 hours later and then I immediately plugged my charger in!

  Something will happen to my computer? Which would cause a detrimental effect for the performance of my battery?

  Thank you!

  No, nothing will happen for her and she will not affect the battery or the computer in anything.

• MacBook Pro won't feed - need to disconnect/reconnect the battery.

  I have a 'early 2011' MacBook Pro 17 "which does not illuminate when the power switch is pressed.    He worked normally in the last time it was used.

  I'm a PC I / specialist t so I did some fault finding.  Here are the results and measures, I tried:

  1. Power button and no indication button has been pressed.
  2. Button on the side and he said fully charged battery.
  3. Adapter a/c and LED power connector attached LED lights up in green as it is supported.
  4. You press the power button - still no indication of any attempt to power on.
  5. Let Reset SMC pressing SHIFT, control, Option, and power switch.  All released.   You press the power button - still no indication of any attempt to power on.
  6. Power button which is held down for 15 seconds, released, then no hurry once - no change.
  7. Disconnected a/c power.
  8. Removed the back cover.
  9. Battery disconnected from the system board connector.
  10. Connected a/c adapter and power button pressed - no change.
  11. Disconnected the a/c adapter.
  12. Back in the connected battery system board connector.
  13. Joint a/c adapter and the system performed a reset, then IPL upward and ran normally.
  14. System "Shut down" and then press the power button - would not be back.
  15. Removed the a/c adapter and pressed the power button - still wouldn't back off.
  16. Disconnected a/c adapter, disconnected the battery, battery reconnected to the system board.  Power button - will not turn on.
  17. Repeat the procedure which worked previously - a/c offline, disconnected battery system board, connected a/c, press button power (no signs of activity), disconnected a/c, battery reconnected to the governing body of the system, reconnected a/c and it reset and power!
  18. Let system and then "reset" (instead of closing) - it restarts correctly.
  19. Shut down the system and then I tried to power - will not turn on.
  20. Bottom line: it seems that the procedure which will get the system starts, after it is closed: disconnected a/c, disconnecting the battery system board, connected a/c, press power button (no signs of activity), disconnected a/c, reconnected battery to the system board, reconnected a/c and it resets and starts.

  OK, so you MacBook Pro experts out there... what seems to be the problem and what measures would you recommend I take?

  THX,

• El Capitan 10.11.2 disconnects from the network of Canon printer macbook pro after each use but with the same OS version iMac remains connected

  How to prevent my Macbook Pro El Capitan 10.11.2 going to disconnect my network printer Canon?   My iMac running the same OS version don't unplug and behaves like any normal wireless connection.  I deleted the printer and added back, reset printing, etc. nothing works.  Given that the Mac is 6 "each other and 5 feet of printer during the last test, it must be something specific to the Macbook.  The Macbook identifies the printer after each reboot the printer as printer Canon right, but once the task is completed does not have the printer.  Everything is on the same wireless network. Computer Windows also recognizes the printer and it keeps alive after printing.

  Please read this message before doing anything.

  This procedure is a diagnostic test. It is unlikely to solve your problem. Don't be disappointed when you find that nothing has changed after you complete it.

  The test is intended to determine if the problem is caused by a third-party software that loads automatically at startup or logon, by a device, by a police conflict or corruption of system files or some system caches.

  Disconnect all devices wired except those required to test and remove all the expansion cards from secondary market, as appropriate. Start in safe mode and log on to the account of the problem.

  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. Ask for additional instructions.

  Safe mode is much slower to boot and run as normal, with limited graphics performance, and some things work at all, including an audio output and a Wi - Fi connection on some models. The next normal boot can also be a bit slow.

  The login screen is displayed even if you usually connect automatically. You need your password to log on. If you have forgotten the password, you will have to reset it before you begin.

  Test in safe mode. Same problem?

  After testing, restart as usual (not in safe mode) and make sure you always have the problem. View the results of the test.

  Any one who knows what is wrong and how to fix it, help would be great.

  The problem is probably due to the discrete GPU failure. Download gfxCardStatus2.3 and use it to disable the discrete GPU. It is of a temporary workaround until you get your motherboard replaced.

  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.

• iPhone 5 s keeps beep when plugged in to the new MacBook Pro

  I just got a new Macbook pro, but when I plug my iPhone 5s into the USB to sync, iPhone guard making the sound perception by beeps constantly. therefor iTunes can not connect to my iPhone.

  Try a different USB port. Or another cable.

  If she is constantly connecting and disconnecting, it might be a hardware problem on the MacBook Pro or the cable.

  Please help, my 13 "Macbook Pro, circa 2011 displays a white screen briefly and make sound boots, then goes to a white screen.  I tried to reset the PRAM a couple of times, no luck, reset SMC strikes did not help.

  Can anyone offer additional troubleshooting steps?

• I have no sound coming out of my macbook pro and see a red light in the hole of the listener.

  I do not have its coming out of my macbook pro os x 10.8.1 but if an earphone is connected I hear the sound and there is a red light through the matter of earphone. What is happening to you can help me?

  The red light of the headset jack means the MacBook Pro thinking that an optical audio cable is plugged into the port. Try to have disconnected and reconnected a headphone plug into the port several times. There is a tiny sensor inside the port that determines if the port is operating in analog or optical mode. Something similar by plugging should trigger the sensor and restore the analog signal.

  If you don't feel capable in doing so the folks at Apple Genius Bar will be able to help.

• Change of keyboard USB external Apple connected to the Macbook Pro

  Dear ladies and gentlemen,

  I need your help. I have a MacBook Pro running the last Sierra 17 "MacOS. I bought a 27 "Thunderbolt display and wanted to use a full external keyboard USB Apple (with the help of the digital keys). I have connected to the screen "USB port, closed down the internal screen MacBook... magic happened... keyboard poped office to the top of the screen external AND external full resolution was working properly..." Unfortunately only for 1-2 minutes, then the layout changed back irreversible in a layout resembling the layout if I would press "alt". Only way I could "resolve" to disconnect the keyboard USB plug and then plug again... but after 1-2 minutes did the same thing...

  I tried to plug the USB plug into the MacBook Pro directly, but the same thing happened...

  I am so unhappy that I can't use correctly the full length external Apple keyboard, large... Any hint/resolution?

  Thank you for your help in advance,

  Péter

  System Preferences > keyboard > Input Sources > [√] see Input menu in the menu bar

  ... then the menu icon before, choose «Show Keyboard Viewer»

  Now, look at the chart of the keyboard that appears on the screen. If the Alt/Option key is stuck, the key will be gray, as if it is held down. If you press it again, he himself is not?
