Similar problem here...
After the install my Mac (G5 dual 2.3) rebooted and once everything started up, the Mac was turned off, just like someone shut the electricity off...
I pressed the start button again, was watching the grey screen for quite a while and same thing happened again.
Tried one more time and then the grey screen seemed to stay and the fans were blowing at top speed... I shut the Mac down and rebooted in safe mode.... (press shift key while booting)
also switched off my external firewire drive which has a Techtool eDrive... These are the Login Items I have:
iTunesHelper
Microsoft AU Daemon
iCalAlarmScheduler
iMsafe
sharkMonitor
free-1 USB Phone
iTunes
StuffitAVRDaemon
MagicMenu
Aspyr Game Agent Helper
any ideas?
I just used Software update to install 10.4.7. All
went fine until the restart. Now all I have gotten
for about an hour is the beautiful gray Apple.
Nothing happens. What next?
