MacBook owners just can't seem to get a break, it seems. The loveable laptops have had a handful of problems since their debut, ranging from the random shutdown syndrome (which was later fixed), to the whirring moo problem (also fixed), to the discoloration issue (yep, fixed), to the plastic cracking crisis (no idea what's going on there). The latest problème du jour apparently has to do with flickering screens, which seem to crop up on an unpredictable basis, but might possibly be triggered by high CPU load. Apparently this issue has been discussed on Apple's own web forums for months, but the particular thread was recently locked for no reason, reports AppleDefects. Further, other Mac sites, including MacinTouch and O'Grady's PowerPage, are reporting similar problems with older PowerBook and MacBook Pros. Hopefully this will all be swiftly resolved with a firmware update in short order. A sample video of the problem can be found on the next page.
