Hi All, I am now on my second Mac pro a 3.1 just put Lion on an 256Gb SSD, fair speed a lot quicker then Yosh 10.10.x with only 8Gb of ram, that must be my next upgrade, some one mentioned cheap 667MHz ram from old servers, anyone know where! and what's cheap. Anyway that's not really my question (but please answer). See the attached image, he has popped up on the desktop a couple of times! But is it something I should know about or something I should NOT be tempted to RUN. Regards Mel.
