I have unsolved problem with my macbook. Once when my mac was alive, I've set rights to all data on mac HD for user 'system' to read-only. Also I do it for the groups 'wheel' and 'stuff'. Only one user account with name 'mac01' has all rights to data on my mac HD. After this (why I made it, I can not explain, it's my fault) my mac goes down and can not boot the system. As decision, I run system in Single-User Mode and type:
fsck -f mount -uw / chmod -R ugo+rwx /
But it still not help me. System still can not boot, and stops above 55% loading apple logo screen.
In Verbose Mode the last string is:
en0: channel changed to 1
then boot stops for unknown time.
Please, help me if you can. I would be appreciate for your help! Thanks.
The last lines in the verbose mode are:
IO80211AWDLPeerManager::setAwdlOperatingMode Setting the AWDL operation mode from SUSPENDED to AUTO IO80211AWDLPeerManager::setAwdlAutoMode Resuming AWDL en0: BSSID changed to 28:28:xx:xx:xx:xx en0: channel changed to 1
and it hangs/freezes.
I did run in recovery mode, run Disk Utility, fsck and verified/fixed the permissions, but it didn't help.
