Hey all, I just updated my powerbook g4 1.5 ghz to 10.5.2. After going through the update, it attempted to restart only to yield the white background with the grey apple logo and spinning icon. I have let it sit on this for over 30 minutes with no avail. I have attempted to safe boot by holding shift on power up i have also option booted and selected the hard drive with no dice. If anyone can offer support that would be great, i have read several threads, but none with the same startup problem as my own. Thanks!!
