Geforce download mac. Hello!
I am running Macbook Pro (Late 2011) on Sierra osX.
First I repartitioned my HD into single partition(I had Bootcamp). After that I went to encrypt my HD using FileVault and it got stuck for days at around 60%. I think the problem might be something with repartitioning the HD but I see others have problem with encryption as well.
I decided to reformat my HD to make a clean install(I have backed up the system with Time machine) after Disk Utility have failed to repair the disk.
Restart a Mac and hold down Command-R after the startup chime sounds, and the computer boots into the recovery mode. Select Disk Utility from the startup menu, and you can erase your startup drive.
- Here are instructions on how to use Disk Utility to securely erase a hard drive connected internally or externally to your Mac. These instructions were written for Mac OS X 10.4 to 10.6. The process is very similar on older versions of Mac OS X, but the screens will look a bit different.
- Other Mac systems (OS 10.7 and newer) cannot erase the drive; Why FileVault 2 Can Be a Pain For a Technician. On several occasions, I've helped clients back up their files with the intention of performing a full erase and reinstall of the Mac OS.
- Select Disk Utility. Select Macintosh HD from the sidebar. Click Erase and input a new name and format. For simplicity's sake, you can leave both to Macintosh HD and APFS or Mac OS Extended.
Now I can not even reformat the HD using Disk Utility from CMD+R mode. Imovie not on mac anymore.
In Disk Utilty I see under Internal 'Apple HDD HTS547575A9E384 Media' under which is greyed out my 'Macintosh HD'. on Disk Images I see 'Apple disk Image Media' which is 2.01 GB and has under it 'OS X Base System'(1.29 GB) with option to eject which does not work. I tried to repair or erase 'Apple HDD HTS547575A9E384 Media' but it does not work. When erasing it says 'Erase process has failed' with details saying 'Couldn't unmount disk - Operation failed'.
What should I do?
Either make the encryption in FileVault to continue the progress which didn't work after reading about it and trying things… or to erase the HD and start a new install from my Time Machine backup. Any help is most welcome!
Is this a good question?
