If booting to Internet Recovery fails, you are correct in thinking the next step is to back up any data that is accessible. Remove the HD from the Mac and read the files from another computer. Boot in to target disk mode and access the files from another computer. Bring a USB drive that you know is bootable by your hardware and boot to it. Bring the Mac to ...

Did you do anything special before the problem showed up? Like performing an osx update? I'm asking because I experienced my SSD going completely dead after an osx update myself before. It might be the disk is broken, especially indicated by the disk not showing up in internet recovery. If you feel comfortable with it, I'd advise you to boot up a Linux ...

Try resetting the PRAM settings. First, restart your Mac, and before you hear the "bing" sound press option key (alt) + command + r + p, it will restart your Mac, after you hear the sound twice just plug in your USB stick and press the option button and boot from there. It worked for me. Hope this helped you out.

Connect in target mode to back up any critical files that are not backed up Boot to recovery and run Disk Utility there to repair the drive. If that fails, Boot to internet recovery and see about reinstalling the OS. Boot to internet recovery and wipe the drive and install Get hardware repair

The issue I was experiencing was due to a firmware lock, likely triggered via iCloud. Because it is a late 2012 model, bypassing the lock is no longer possible by removing a stick of RAM and resetting the PRAM. It is locked-out by an EFI chip that executes the lock routine before booting. My only options er on the side of more extreme hacking (via reflow ...

Make sure your Mac is off (not just standby) and turn your Mac on like you always do, but hold the Option key at startup until you hear the boot chime. You'll see a bunch of images of HDs in a row, use the arrow keys to select the drive you wish to boot from and then press Enter. Your Mac should now startup using the selected drive this time, but to make it ...

This means the hard drive is encrypted. Boot the machine up, go to System Preferences > Security > FileVault and enter the password to decrypt the volume. EDIT: If you don't have access to the drive/password, force boot to Internet Recovery by holding [CMD] + [OPTION] + [R] and you should see a spinning globe (you'll need to have Internet access).

It seems it was the SSD. (Or the SATA controller - I'm not quite sure yet.) Removing the SSD from its plug caused the Mac to at least display a black and white folder icon with a "?" inside (like here: https://support.apple.com/HT204156) That gave me hope so I purchased a Transcend JetDrive 725 for Macbook Pro Retina Early 2013 and inserted it. Wohoo, ...

I had same problem of progress bar hanging halfway through startup. MBP early 2011. Visited Genius Bar and the guy there said almost straight away he thought he knew what the problem was. Turns out it is the video card. They are going to replace the main logic board and the video card maker is going to stomp up the cost. Apparently on this laptop there is a ...

Already tried NVRAM reset? I've been surprised by how many problems this "fixes": https://support.apple.com/en-us/HT204063 Turn on your Mac. Press and hold the Command-Option-P-R keys immediately after you hear the startup sound. Hold these keys until the computer restarts and you hear the startup sound for a second time. Release the ...

The only way to do this is to install the windows version that your mac accepts at first then once installed you can upgrade to Windows 8 from there.

Before you're able to create a bootable OS X installer, you'll need to do the following first: Download the OS X Installer app from the Mac App Store. Mount the volume you want to convert into a bootable installer. This could be removable media such as a USB flash drive, or a secondary internal partition. You can then use the createinstallmedia tool to ...

I attach answer here as you guys suggested. SOLVED - Bootcamp Windows 7 installation without USB, ODD OK, I'll explain how I worked it. I followed almost of all of David's method here and here, but there are little differences. Before we start, please note that I'm using MacPro4,1 which does not support USB installation of boot camp and I detached ODD. ...

The answer is you can not period. Your Mac's firmware does not support booting any windows installer from a USB port. I assume your Mac does not have a working DVD (optical) drive. If it did, using a DVD would be the recommend way to install Windows on your model Mac.

In such cases I, myself, do a boot into DFU mode which actually uses way less energy mainly because the display stays off. Then I wait for about a half an hour and then I reboot the iDevice in order to have it properly booted. P.S. Follow this procedure in order to enter an iDevice into DFU mode: Make sure your iDevice is plugged into a power source via ...

Installing Windows on a Mac via Boot Camp you only have two choices, DVD or USB. You also need a Windows DVD (Full Install Media not Upgrade Media) or an ISO Image of the Windows DVD to create the USB Installer via the Boot Camp Assistant. Yes, you'll be able to use the USB drive to store other files after the Boot Camp Assistant has written the files ...

I fixed it. Turns out, the phone was on 4.999% when it was starting. When it hit 5.000%, it started up. Because starting up used so much energy, it used more than the cord could provide, causing it to fall back below 5.000%.

If I was in the same or similar situation, this is what I'd try... Using another Mac I'd download Yosemite from the App Store and then create a USB Installer. Next I'd boot the Mac with the Yosemite USB Installer and install Yosemite to an External USB Drive, preferably a USB 3.0 HDD/SSD or even a large Thumb Drive. Once the install to the External USB ...

This is probably caused by the famous GPU problem these MacBook have. Do a search on Google for Late 2011 MacBook GPU problems and you will find loads of information about this. Apple finally recognized the manufacturing error and has a program in place to replace the logic board under warranty. I had mine replaced a couple months ago with no costs at all.

Safe Mode working means that it is likely that something you installed is preventing the OS from booting. Specifically programs you have added to start at login in your user account or other things you may have installed that adds kexts to the system. Look in System Preferences > Users &Groups > Login Items Remove them all and reboot. If it boots one ...

Could be the keyboard, where the power button is not working right (my sister had a MacBook Air that did this). Massage and blow compressed air into the power button and see if that helps.

You could also add some kind of boot manager, as Refind or the defunct RefiT. Thoses will remember the last choise you did, pkus, they are highly configurable.

You can set the default boot partition from the option-boot screen. Press the Control key while clicking the arrow beneath the drive, and that should do the trick.

In the end, i send it to some expert to check on it. There is two reason the machine is slow: 1. KVR ram is used for the machine 2. The HDD is most probably faulty. Swap this two things out it worked fine.
