Installation of Yosemite stalled as hdd locked Today I was installing yosemite on my macbookpro 2013. 15inch. everything went smoothly till after restarting for further installation it states unable to install as hdd is locked. it then goes to disk utility. How should I continue when hdd is locked. the worse thing is i did not do any backup. please help

In Disk Utility click on the drive and click on "Enable Journaling" and it should fix the locked drive.
