Several months ago I began having random crashes on my iMacG5 PPC OSX 10.4.x, and after several bouts with checking/repairing permissions, repairing the disk, doing installs, re-installs without importing preferences, etc., re-format entire drive & install everything including applications, new preferences, etc. from scratch I gave up and took the computer to the local Apple Store. They ran their diagnostics, I purchased and ran MemTest for about 4 hours, removed ram, etc. and the problems persisted. Finally got Applecare to throw in the towel, and have someone come over to install a new logic board. When the service tech guy from CompUSA opened up the back of the iMac, he showed me several burned diodes, that apparently were the source of the problem, even though they did not show up on Apple Store's Diagnostics. For about a year or more the machine ran great. A couple of months ago I began having some very bizarre corruption, primarily issues with the dock. Due to my prior experience with the burned diodes, I focused my investigation in that direction. I went back to the Apple Store, a day after I had completely re-installed everything again, and they could find nothing wrong with the hardware. In fact the machine booted from one of their drives just fine. I gave up, and shelled out $2700 for a new iMacG5 Intel machine. Within 3 weeks the new machine began having exactly the same problems. This is when I began suspecting some sort of a virus, worm, trojan, malware, etc. Something had spread to my new machine. I isolated all the computers and began documenting (mostly with screen- shots) the problems in order to try to try get some help. Mostly to see if anyone else had encountered the bizarre behavior I was experiencing, and if they had any solutions. I was not going to post on this board because I felt it was not related to MacPorts, but now for info purposes I thought it might do some good, since this forum has some very knowledgeable people. I thought perhaps I might get some insights from some of you. Thanks for any insights or help you might provide. http://www.mac-specialist.com Best Regards, Bill Hernandez Plano, Texas
