Cant get anything from holding "C"
Cant safe boot

Only single user start up

What OS X version?
Did you have permissions problems before this issue?

This will run permissions repair from commandline (single user):
diskutil repairPermissions /

had to order snow leopard 10.6.3
not sure what was on there b4 as i got this from a friend

only used 1 day and worked fine but i do remember going into permissions so Im
sure I changed something

where do i go to type this command? I cant get to anything?

sorry I just saw single user command line

What does it mean when the graphics for desktop come up but no icons or text?
Is the OS on there already?

Cant run this command as it says

Unable to use DiskManagement frameworkas DiskArbitration framework being unavailable in due to being booted in single user mode???????

Those are interesting questions that I don't know the answer to...
(I'm not going to experiment in Single User - sorry)
