hou to upgrade power pc g5 running 10.5.8.i want to upgrade to 10.6.8
A G5 can't be upgraded past 10.5.8.
Read this tip, if you get a machine you can upgrade to 10.6 or later:
Only 2006 and later Macs with an Intel CPU can upgrade to 10.6 or later.
If you decide, at some point, to purchase a newer, used Mac, get something that is year 2007 or greater.
A 2007 iMac, for example, can run OS X 10.6 all the way to OS X 10.9.
The 2007 model Macs and up can take more RAM than 2006 models.
