After a long, and quite disheartening, series of hardware problems with my HP laptop I decided to try out a Mac (late 2009 Intel based 19.5 inch). In the months since January past I have discovered this to be no significant improvement and I have grown tired of the persistent wireless connectivity problems and am totally put off by the upgrade to OSX-10.6.4 which killed HD graphics using Open-Gl. Since July, trying to use HD on my Mac now blackens half the screen and then locks the system. I am contemplating wiping the system and installing CentOS-5.5 instead. Before my frustration leads me to run straight on into a wall, what can I expect to NOT work on the Macbook if I do this? I do need wireless, albeit I really cannot say that I have it now. I also dearly would like to get back HD graphics as well. Regards, -- *** E-Mail is NOT a SECURE channel *** James B.
