Leopard (10.5) SUCKS on a G5 - avoid at all costs. All the software fixes and patches released (called Snow Leopard) do not work on a PowerMac
I don't understand this at all. Leopard runs fine on my 1.25 GHz G4 with 1.75 GB of RAM. How does it run worse on what would undoubtably be better hardware? I mean, you have a better memory subsystem, automatically it'll have a better video card, and I think all models support SATA which will give a little boost over older models that sport only IDE.
Snow Leopard (10.6) isn't really "software fixes and patches". That's what 10.5.1, 10.5.2, 10.5.3, etc. are. 10.5.8 was released in August of 2009 so it's not like 10.5 is an abandoned platform. Certainly Tiger (10.4) is far closer to being on its way out from mainstream support for Apple. And 10.5 was when Apple pretty much solidified their APIs--before then, 10.4, 10.3, 10.2, that stuff was in flux so programs written for one version of the OS might not work on a later one. I'd think 10.5 would be a better bet in that regard.
10.6 is smaller because Apple ditched the "fat" binaries and PPC support. There's some multi-core performance tweaking, too, which I suppose would have been useful to a quad-core G5 but probably not much of a gain for dual-core G5's and G4's. 10.6 is not a "fix" of 10.5. The many updates and patches for 10.5 are. 10.6 is more of a performance and finetuning update.
Maybe you had bad luck with 10.5 on your G5, I dunno. But I haven't really seen much backlash about Leopard on that platform and just wanted to clarify lest other people reading this think that 10.5 is completely buggered on the G5 platform.
