imac boots only in safe mode, what's wrong?
Maybe somebody can help me out here.
My 24" imac dual 3ghz running 10.5.8 will only get as far as a blue screen loop with short flashes every 8-10 seconds. Safe mode is the only way to boot up and the flashes continue in that as well. There is also a short orange flash while the screen is still grey.
Attempting to boot from the system dvd results in a grey screen that tells me I need to restart. Booting from another system hard drive results in freezing - the wheel under the Apple logo stops spinning.
I have tried resetting PRAM and SMC. Repaired Permissions using Disk Utilities and Disk Warrior. Checked the hard drive, no problems. Did the hardware check (boot pressing d), which claims everything is fine.
Does anyone have an idea what's wrong with my machine?
iMac, Mac OS X (10.5.8)
