I have done quite possibly THE dumbest thing I could have done and now I cannot boot past the white apple screen with the spinning progress wheel.
I was setting up FTP access on my computer and wanted to limit what files/folders the new user could see beyond the default settings. I used "get info" to edit permissions on files/folders and in the process, unknowingly edited the custom hard drive permissions. Since rebooting, I'm stuck at the white apple screen.
I have used install disk to boot up, accessed disk utility and tried everything I could think of including - verify and repair disk, reset passwords and ACL's to all users. I tried to verify/repair permissions and it errors out on exit and fails. I tried to run an archive and install and it failed and now I can't even access the option to try again.
I do not have a recent time machine back up so I don't want to use that. (it's from 2010) I also did not have a disk image saved prior to this problem but, I did make one now and stored it on my external drive in hopes I can recover files from it if I cannot fix this problem.
I can access terminal but am unfamiliar with what commands I can use to access and modify permissions.
Some questions I have for anyone willing to help.
Can I restore just the permission settings using my old time machine back up? If so, how? Keep in mind I can only work from the install disk as my computer won't boot. But, time machine is saved on my external hard drive if that helps.
Can I somehow force the archive and install option to reappear on install disk menu? It's currently greed out because it failed once. I want to try it again and uncheck the box to archive settings and permissions because I had it selected the first time and probably shouldn't have.
Is there a set of commands I can use in Terminal to access and fix the hard drive permissions and if so, what are they? I've tried looking and find it difficult to determine proper spacing,terms,etc.
Is there anything at all I can do to fix this that I haven't thought of?
Thanks in advance for any help.
