Installing Tiger last night over Panther 10.3.8 everything goes good until the end where I get a Install did not complete, please try again error. I tried this twice with the same error. First time I had trouble rebooting and had to reboot using option to choose the start up disk....after the second time there are no apparent issues. I updated with Software update to 10.4.1 and everything seems good. Seems a little slow though. I have a dual 867 G4 with 1.25 gigs of ram. From what I had read, I might have a memory issue with third party memory? My question is, should I try and reinstall again after removing the ram? or should i be ok as is? The install seemed to fail after all the languages finished installing...not sure what is after that? Optimization maybe?
