Hello,
I have a mac book air 2011 with 10.7.5.
Yesterday I bought the update for 10.8 in the Apple Store but always the installation failed. I can't recovered my computer after the failure instalation and I need to use the time machine backup for revocer the environment.
Screen shot of the failure:
"Recovery system creation failed with error -69840 (File system check on boot helper partition failed)"
Thank you 🙂
MacBook Air, Mac OS X (10.7.5)
I solved it. I have needed disable FileVault before try to install 10.8.
In other words:
See you...
