We have 2 Macs, the first is a Power G4, and the second an Intel G5. Both updated to Leopard. DH installed 10.5.7 on the G5, and the hard drive failed immediately. We got that replaced, and the machine is now running fine. My question is, do I install this upgrade on the G4? The Apple forums were in meltdown over the problems this upgrade has caused, and I absolutely cannot afford at the moment to have any major repair work done on the G4 (not that there is anything wrong with it just now!). The technobabble on the Mac forums can leave me even more confused than normal I know I haven't been online in ages, due to some serious family problems, but any advice will be most gratefully accepted. Thanks.
