    10.6.8 worked flawlessly. Upgraded to 10.7.0 and then 10.7.2. All looked good at first. But now every so often (like every 15 minutes), the contents of the screen will disappear. The screen goes completely blue for a couple seconds, and then back to normal.

    The computer is usable, but just a periodic annoyance.

    Ideas?

    I believe my problem was related to the CMOS Reset issue. Running this command seems to have fixed both issues:

    sudo perl -pi -e 's|\x8b\x45\xc8\x39\x45\xcc\x74\x0b|\x8b\x45\xc8\x39\x45\xcc\xeb\x0b|; s|\x8b\x45\xb4\x39\x45\xb8\x74\x08|\x8b\x45\xb4\x39\x45\xb8\xeb\x08|' /System/Library/Extensions/AppleRTC.kext/Contents/MacOS/AppleRTC
