Let me state very clearly that it is not my intention to pick up a zeallot fight. I am NOT a hacker, I am not an expert, just your regular user who has found a couple applications he/she depends on, and uses them regularly. I expect thousands of such users to be in the same situation as I am now, and thus I decided to share my experiences.
I use a quad-processor Mac G5, 2.5 Gb memory, Quadro 4500 Video Card driving two Cinema 30 inch monitors. The machine has 750 Gb internal disk, plus 4 Tb of external disks. Not a low end system, not one that can “barely run” the OS. Further, with OS X 10.4 the machine was a screamer, running Aperture with thousand of pictures of 20 Mb each, and at the same time flying through three or four other simultaneous heavy-load programs like Photoshop.
So, one day Safari breaks.
