My Mac turns on but it gets stuck on the white screen upon startup after the chime. I have OS X 10.7.5
I have tried many things unsuccessfully like:
CommandR: Boot to OS X Recovery Mode => The window does not pop out.
Option: Access Mac Startup Manager => When I choose the Recovery disk, again it goes to white screen.
Option: Access Mac Startup Manager => Again it goes to white screen.
I reset CommandOptionPR: Reset PRAM => with no luck
I reset SMC, disconnected the battery cable and held the button for 5 seconds => No luck
Used CommandS: Single User Mode => Type
fsck –fy and press Return
/sbin/mount -uw /:
hfs: Removed 2 orphaned / unlined files and 0 directories
touch /private/var/db/.AppleSetupDone exit
=> This didn't work either
When I connected in Target Mode T via Thunderbolt cable to another Mac => I was able to scan entire disk drive and fixed any errors on disk => but now still unsuccessful with boot up.
When I was in Verbose Mode I noticed the following line:
SMC: :smcInitHelper ERROR: MMIO regMap == NULL - fall back to old SMC mode BootCacheControl: Unable to open /var/db/BootCaches.playlist: 2 no such file or directory
Do you have any recommendations what I should try next?
