Apple Event: May 7th at 7 am PT
I have a 2011 Macbook Pro. When I attempted to install the most recent update to 10.9.4 the installation process froze with "1 minute left" for over 30 minutes. Now the computer will not even boot up, even in safe mode. Unfortunately I do not have a recent hard drive backup so any fix that would keep my data intact is preferable. Thanks!
Hi LenaAnne
How far does the Macbook get when booting?

Boot into the Recovery Drive by holding down Command R when restarting.
Run Repair Drive and Repair Permissions using Disk Utility in Recovery.
Restart and see if that fixes the login problem
If you still cannot login, boot back in recovery and reinstall OS X. This process should not damage your data but it's always advised that you backup first.
Also while in Disk Utility in recovery, check how much free space is on your drive.
It gets stuck at the gray screen with the spinning gear.
Thanks. I tried repairing the drive and permissions. Still wouldn't load. I also tried reinstalling OS X from the disk utility. It downloads but never restarts. I tried to manually restart but it still gets stuck on the screen with the gray apple and the spinning gear. When I rebooted into recovery mode it downloaded the OS again but still no dice. Is there a different way to reinstall OS X? I have over 200GB of available memory so storage shouldn't be an issue.
You are a bit limited on creating another installer since you can only boot from the Recovery Drive.
Try creating a second partition in Disk Utility in Recovery on your internal drive. Click on the + sign and it will make a second partition.
Select to install OS X on this new partition.
Let me know if this works.
Do you mean the + New Image button? That gives me the following message - "Unable to create "Macintosh HD.dmg." (Invalid argument)".". I'm really beginning to regret installing that update...
No, see this article for help.
