Hi everyone, I found 2 weird bugs on my iMac G5, 1.8 ghz, 1Gig Ram, after updating the system to 10.4.10. 1) I cannot boot from external drives anymore! Although I could using 10.4.9, now I cannot... 2) I cannot play DVD from videolan (the last version, 86c) although the same DVD plays well with DVD player. I repaired the system to see if that would help. Did not. I tried reinstalling the upgrade (using the safe mode), didn't help. What is worse is that I did not have any error or weird behavior during the updates. Booted twice... very normal. I have no sound problem so far. Someone has similar DVD and external booting bugs???
