Hey, I'm new here and I wanted to start with A question. I Own A Mac Osx 10.5.8, which I bought in mid-2008, and recently I have been having a few problems with it. Just to clarify A possible cause of some of the problems that I have. (I am running Blender, Sketchup Pro, and several other design programs that might be responsible for the issues.) Let's get to the issues now. The computer is very slow. Around two years ago I put extra memory in, and that seemed to save it for A while. Now, programs become unresponsive and crashing is a major problem with Chrome, Safari, Firefox, Sketchup and about everything else. Finder has become slow and I get the Spinning beach ball more than most of my search results. Restarts are also A developing problem. It is a serious pain having to restart or Force quit. The main question here, is with the work I do, what is the expected life span of my Mac, and what should I do about it???
