El Capitan broke my Macbook, what are the chances of me saving this Macbook Pro?
My girlfriend has a 2011 Macbook Pro which had Yosemite on it. After installing El Capitan on my 2015 Macbook Air, I decided to update her Macbook Pro. Since I tried to update it, we're just in an endless loop of rebooting and the Macbook Pro says: "an error occurred while preparing the installation". I've searched the internet for many, many hours and found that the "fix" was to do one of the following things:
- Set the date in the terminal using something like: datentp -u time.apple.com
- Reset NVRAM/PRAM
- Reset SMC
I've done ALL of this and when I run "repair" in Disk Utility, it tells me it cannot repair. So today i'm going to boot up whilst holding 'T' and attach a thunderbolt cable from her Macbook Pro to my Macbook Air.
What are the chances of me being able to recover her data? And what are the chances of me being able to erase her HDD after i've transferred data and installing El Capitan?
P.S - On a side note: I am very, very disappointed with Apple for the El Capitan upgrade. It has made my girlfriend's MBP unusable - and it was fine prior to trying to upgrade. It is fully OEM, has no 3rd party RAM and has always been treated with care.
MacBook Pro, OS X Yosemite (10.10.5)
