I was excitied when leopard came out.. I bought it on day one I installed it on my Dual 2.0 Powermac G5, 3GB X800XT, after I did a backup install went fine. I had some issues with my Sonnett Sata card with my other drives.. but they seems to be ok now. But it seems like everyday photoshop freezes.. or safari.. or it hangs when booting.. or shutting down.. I get all sorts of random errors.. and app crashes.. overall much less stable when tiger. it makes me want to scrap Leopard and go back.... but leopard has some nice features and im just trying to bear with it.. until some real update get posted.. 10.5.1.. didnt really fix anything. I have already done 3 fresh installs with leopard. its the same at my work. where i have a 2.6 Mac Pro, with 4Gb,x1900 crashes here and there.. slowdowns... driving me crazy. until apple really puts some effort into updates.. I think Leopard sucks. Guess i shouldnt have jumped the gun and installed it..
