Could not boot after upgrading to 10.10.1

[scleone1987]

Hi all,

this morning my Hackintosh notified me of the new update, 10.10.1. After having downloaded it and rebooted, the computer shuts down after few seconds. So I booted in verbose mode, the attached pic shows what it tells me a second before shutting down. What can be the problem?

It could be just a bad kernelcache. Boot -s (single user mode) clear the cache for a start. Assuming that you know the procedure for this or google it.

Hi Onixs,

first thank for your reply. I googled it and so tried both this two commands in single user mode:

 

sudo rm -r /System/Library/Caches/com.apple.kext.caches

and

 

sudo touch /System/Library/Extensions

but no luck, it tells me "Read only file system". How can I fix this?

Edit, I tried first "/sbin/fsck -fy" and "/sbin/mount -uw /",

then I tried to clear kernel cache. Still no luck... You can see the attached pic

What is the bootloader you used?
