You try 'GraphicsEnabler=No' with that 660ti?
That wasn;t the issue... The problem is FCPX! Lockups occur when FCPX is in use. Same as 10.8.2.
No joy for me: can't boot since using the combo updater.
My setup: Customac mini deluxe 2012
Tried booting from the HD, as well as using my Lion unibeast USB flash drive. Unplugged all USB devices, except for the Unibeast flash drive. Last few messages at the console are about Bluetooth. I usually use the Targus USB Bluetooth transceiver.
- Motherboard: Gigabyte GA-Z77N-wifi
- CPU: Intel Core i5-3570K
- GPU: EVGA GeForce GT 640, with 2GB RAM
- RAM: 2 x 8GB
I'll keep reading through the comments: hope someone has seen this and figured out a fix.
