Computer formatting and installation of El Capitan

Hello everyone.
Because I had to finish my thesis, I was forced to create a Linux partition on my Mac, with the addition of a bootstrapper.

Given that I experienced a few problems to update my version of MacOs (sometimes bootloader not was not loaded when the computer was on and automatically started MacOs), I stopped to update software to version 10.10.1 (Yosemite).
Now that my thesis is completed, I would like to completely format my computer, removing Linux partition and restore the entire disk with MacOs. At the same time, I want to update the operating system to the latest version of El Capitan.
What is the procedure to get it all?

Thanks for the support.

I suggest you to download setup OS X El Capitan, put it in a flash drive, make a backup of your files and use the flash drive to format the drive and install OS X El Capitan.

  1. Open the Mac App Store and download OS X El Capitan. The installation program displays upward when the download is complete, so shut up.
  2. Download DiskMaker X and use it to create a bootable USB key with the installation program. You need at least a 8 GB flash drive.
  3. If you have not already done it, make a backup of your files on an external drive with Time Machine-> use Time Machine to back up or restore your Mac - Apple Support
  4. Hold down the ALT key during start up your Mac to the top, choose your USB drive as boot drive and wait while the installer for OS X El Capitan interface load upward.
  5. Open utility disk, choose your internal drive at the top of the sidebar and format him. Don't forget to format the new partition with "OS X Extended (journaled)" as the format.
  6. Close the disk utility and reinstall OS X.
  7. At start-up, OS X will ask you to restore a backup, if you have a. Connect the external drive with the backup, and then follow the steps. It will allow you to restore only the files you choose.

  • cannot restart the computer after the installation of el capitan 10.11.3

    After installing el capitan 10.11.3 on my iMac intel with lyon, my screen is gray and I can't restart.  I lost the free memory.  Help!

    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 support articleto the title of the "Instructions for the backup on an external hard drive via disk utility". The article refers to the start of a DVD, but the recovery mode procedure is the same. You don't need a DVD if you use OS X 10.7 or higher.

    (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 restart automatically in the installation 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.

  • network computer detects and installs but won't print on shared printer

    I have a HP C4680 hooked to my beta Win 7 Ultimate 32 bit version office running with a USB cable.  I have an Asus EEE netbook running than Win 7 Ultimate 32 bit Retail Version.  It detects and prints on the thin printer on the network.  I have a laptop HP slot as Windows 7 Home Premium 64 bit Retail Version.  When I add printer and select network it finds connected to the desktop computer and goes through the installation, but it will not print to it.  It is as if it were the case.  There are no errors, but does never print anything.

    Any suggestions as to why does not print just a computer?

    Thank you

    In the case where someone else faces ever I think that the problem has to do with a 64-bit computer, I try to print to the 32-bit computer.  There was a bizarre behavior last night.  He would print document a specific word, but nothing else.

    After some additional research I found two things to try.  I've done both, so I'm not the one who fixed it for sure, but everything works fine now.

    First, I installed the printer drivers 64-bit on the desktop hosting the printer.  Then click on update driver for the printer from the laptop 64 bit.

    The next step, I took suggested that set the permissions of folder windows/system32/spool to everyone on the host computer, I saw.

    After doing these all works very well, and my wife is happy, that it can print.

  • Install security updates "successfully", but then my computer downloads and installs the same updates again

    Original title: at Microsoft course to resolve this ONGOING problem, & VERY BORING PROBLEM with his Windows security updates?

    Morning everyone,

    There was considerable number of complaints about the failure of Microsoft to solve the problem with its updates of Windows, including updates security for XP, Office 2003, the removal tool malicious and the infamous KB2538242!  I saw these varied complaints not just here, but on some other sites as well forum.

    In the evening of Tuesday, July 12, 2011, I once more has received notification of Update icon in my taskbar and clicked on it to start the updates.  According to the list, there were 5 so-called updates downloaded & installed... as shown below: (my auto-mises update is updated every day at 01:00):

    KB2555917 (a security update for XP)

    KB2538242

    KB2493523 (a security update for Office 2003)

    KB890830 (updated Windows Malicious Software Removal Tool)

    KB2507938 (a security update for XP)

    SUPPOSEDLY... .these updates have been installed.  But, just as happened previously, Microsoft Update icon still reappears in my taskbar within 20 minutes the so-called updates being completed!  Yet once, I went through this cycle of "download & installation" these supposed updates 4 different times before visiting the account that Microsoft has NOT YET SOLVED THIS CURRENT QUESTION! There is absolutely NO help is available, whether of Microsoft at all... except if you're loaded with money to spend on paying them to offer some apology for the problem.  Here ARE the UPDATES security AND in accordance with the PROTOCOLS of MICROSOFT, MICROSOFT IS supposed TO BE PROVIDING SUPPORT FOR THE QUESTIONS OF THIS TYPE! 

    When the problem instead of turning its back on its customers with the blade go Microsoft to wake up and solve this problem continues is to excuse this "oh, there is no support available for these security update issues... unless you are willing to PAY SOME COSTS FOR the SERVICE?  (It was the response I got from one of the support staff for the customer to Microsoft by phone, said by the way!)

    You VERY DEFINITELY have an ongoing responsibility to your Microsoft customers.   What you do to solve this maddening, growing problem, and how a Win XP SP3 client can get any help?

    Welcome & thank you for your comments.

    Please keep us informed of any progress you make, Pete.

    You must set your BIOS to start on the DVD from the beginning to the top.

    You have a good DVD of Vista (OEM/upgrade or full version) and NOT only a recovery disk provided by the manufacturer of the PC (or you burn you).

    For a DVD upgrade, follow the method here and make sure you format your HARD drive thanks to the tools of "advanced install" on the DVD.

    If you have a full version of Vista rather than a version upgrade then just do the first part of the above procedure.

    Since the installation of El Capitan, my streaming to my Audioengine DAC D2 cut after 12 minutes (the default duration of sleep). It will restart by pressing the space bar. When I change the duration of sleep, the cut outs are becoming more frequent and intermittent. Help?

    I checked the wifi and changed frequency (new modem, frequency change made no difference). The Board battery seems fine - all updates well. My computer is an iMac (2011), 3.1 GHz Intel Core i5, 8 GB 1333 MHz DDR3, with a new AMD Radeon graphics card. I recently installed a State strong 1 TB SATA drive and fitted with a LaCie Porsche 4 to USB for backup and a 4TB disk storage RAID LaCie drive.

    I'm frustrated, having to come in my computer since my living room every 12 minutes to continue to listen to Spotify on my stereo system.

    My guess is there a bug in the software of sleep in El Capitan, which disrupts his (I've tried different USB ports connect the Audioengine sender and same thing).

    Should I go back to Yosemite?

    I have recived portable computer of the Government with windows pre installed 7professional but now I want to format and reinstal it I require the startup disk and product key (my OS is authentic)

    If it's a copy of volume license installed, you will need to contact your employer to find the product key and get the installation files.

    If it is preinstalled at the factory with Windows 7 Professional, then use the recovery partition to reinstall Windows 7.

    New computers coming often pre-installed with Windows 7 have what is called a recovery partition. This is used to reinstall an operating system in the case of a system failure. To access it, you need to start when you start your computer by pressing a function key. This can be either F1, F2, F9, F10, F11, F12 key DEL or tab. See the manual that came with your PC for instructions on how to reinstall Windows.

    This is how the recovery partition is accessible to most popular brands...

    For Dell, press CTRL + F11 directly after switching on the device

    For HP, press F11 directly after switching on the device

    For LG, press F11 directly after switching on the device

    For Toshiba, press and hold "0" BEFORE and during the power upward

    For Acer, press and hold ALT + F10, as soon as you see the logo

    For Asus, press F9, as soon as you see the Asus logo.

    For Samsung, press F4 to the power upward...

    For Fujitsu, press the F8 key directly after the power

    Advent, restart your computer. Then, press F10 repeatedly until the message "Starting system recovery"

    Sony VAIO, reboot and press "F8" or "F10" repeatedly until the screen "Advanced Boot Options".

  • My 2 TB TC is full and will not back up. Yet, I have only 1 TB of data on my laptop. Note that I've reformatted the laptop since the last backup with a clean installation of El Capitan.

    My 2 TB Time Capsule is full and will not save. Yet, I have only 1 TB of data on my laptop. Note that I've reformatted the laptop since the last backup with a clean installation of El Capitan.

    I bought a 2 TB external hard and have used Time Machine to back up. But I also use my time Capsule, which I save wireless.

    Any suggestions on getting my TC back up?

    One suggestion would be to copy all existing backups that are now on the Time Capsule 2 TB hard disk. Then, clear the TC and start over again with new backups.

    A more expensive option... assuming you want to keep all old backups on the TC... would be to add a new TC and start backups goes in this direction.

    Another option... If you do not need to keep all old backups now on the TC... would be to erase the TC and start over again with new backups. The benefit of doing this would be that no new material will be necessary, but the downside would be that you lose your old backup history.
