Hi,
After a reset my iMac freezes during startup on a grey screen however the recovery mode and the safe boot mode work normally.
This is the recent history of my Mac: i recently installed a SSD and a few month ago white vertical lines have appeared on the screen that can be see only by very close to the screen.
I've tried:
- PRAM and SCM reset
- clean installation of OS X
- verify and repair the disk and disk permission in Recovery mode
- change the position of the RAM
- reinstall the old hard drive
- change the desktop resolution
the DVD player doesn't work so I can't use the Apple Hardware Test
In the verbose mode I found the following messages:
BootCacheControl: Unable to open /var/db/BootCache.playlist: 2 no such file or directory
bash: /etc/rc.server: No such file or directory
bash: /etc/rc.installer_cleanup: No such file or directory
Logging into single user mode I solved the first message with this:
mount-uw /
rm -rf /etc/launchd.conf
rm -rf/System/Library/Caches
reboot
but the other two message continue to appear
I thought it was a problem of video card but the Apple Care said that if it has a problem the recovery mode would not work
Which you think might be the problem?
P.S. Sorry for my bad English, I'm Italian
