I have updated my MacBook Air 2011 from the App Store to Mavericks but after the installation it doesn't boot up (spinning grey ball). Safemode or a new installation didn't help and verbose mode ends on
"bootcachecontrol: unable to open /var/db/bootcache.playlist: 2 no such file or directory"
bootcachecontrol -f /var/db/bootcache.playlist generate /dev/rdisk0s2
in single user mode but that returned me a
bootcachecontrol: unable to determine uuid for volume /dev/rdisk0s2
message. Every time I want to access diskutil it ends with
How can I fix it?
