My friend has an iMac version 2.1 Power PC G4, 700mhz, 40gig hard drive (22gig free), 384 ram (128 + 256), OS Jaguar 10.2.8. He would like to upgrade to Tiger. But before he buys the discs I asked him to wait till I got some advice from this forum, so here goes... Even though he meets the minimum specs for Tiger I'm thinking he would be better off with more ram. The max ram for this m/c is 1gig. Would it really stuff things up if he replaces the 256 stick with a 1gig stick making 1.128ram? If so, would replacing the 256 with a 512 be enough to run Tiger? Can anyone foresee any problems upgrading from 10.2 to 10.4 (ie. missing out 10.3)? Cheers!
