Hoping that someone can help.  My iMac only boots in safe mode.  Here are the things that have been done:

 

> permissions repaired from Snow Lepoard OS install disc boot

> checked smart status of HD

> unplugged all peripherals

> tried different keyboards

 

This seems to have happened in stages.  I first noticed that this machine would not connect to my LAN via airport, then ethernet.  When I went to do a disc utility check/repair via booting from the OS install disc, disc utility said nothing was wrong.  The HD status also appears to be normal.  I have run permissions repairs multiple times and the same list of repairs are made repeatedly without variation.

 

But now the machine will ONLY boot in safe mode after a full shut down.  It will not restart and boot into safe mode.  Can anyone out there provide any guidance?


iMac, Mac OS X (10.6.8)

    Zap the PRAM and Reset the SMC, then try again.

    Thanks.  Tired this twice but to no avail.  Same issue.  It boots then the apple logo disappears and a circle with a line through it appears and the boot hangs.  It will boot off the install disc.  The harddrive reads and writes fine in safe mode.  Any other thoughts?

    While in safe mode, create a new admin user account, turn off autologin, log into the new account, and see if the issue persists. The circle with line through it indicates that the boot system can't find a viable bootable volume, which usually means that something's corrupting the normal startup process. Alternatively, while in safe mode, move the entire /Users/username/Library/Preferences/ folder to the Desktop and see if the machine boots normally. If so, then you're in for a time-consuming process to determine the corrupted or conflicting preference files.

    Thank you for your continued suggestions.  Neither creating a new user in safe mode or moving users/username/library/prefs helped.  I'm stuck in the same boot hand with the circle and line through it.  Is it best to replace the harddrive and go with a fresh install at this point?  Or do a clean install on the disc and then move the applications that are needed?  Very frustrated.

    Reinstall the OS and see if that fixes the problem. If not, then do a clean install and migrate the apps, users, and network settings.
