I have connected 2 macbook pros using firewire in target disk mode and the permissions on the destination macbook pro have changed. Now when I try to start the macbook pro, it stays on the grey screen and the apple sign changes to a prohibitory sign, therefore I cant log in.
Please help!
Thanks
MacBook Pro (15-inch Mid 2010), Mac OS X (10.6.8)
I am unable to perform a safe boot, it simply wont happen.
I tried to start from mac osx install disk and that works so I am able to go disk utility, I can run 'verify disk' and 'repair disk' and it shows that everything is ok, however, I cant 'verify disk permissions' or 'repair disk permissions' as both are greyed out because 'the selected disk is not mounted'. I try mounting but that wont work either, I am told to 'disk can not be mounted, run first aid first and then retry'.
Furthermore, I try to perform 'archive and install' so I follow these instructions:

But on number 7, intead of being able to choose volume to install to, there is nothing I can choose! There is no list. And of course I cant continue.
Any help is appreciated!
