Thanks to the announcement here of success with Spctraview and 10.8.3 I downloaded this latest version of Mountain Lion. I have submitted my not-so-good experience to MacInTouch and I am sharing that posting here as well. I'd greatly appreciate any thoughts on what went wrong.
I loaded 10.8.3 (was using 10.7.5) this weekend, looking forward to being able to use Spectraview ll software to color calibrate my NEC P221W monitor. The ability to do so was broken with 10.7.5 but restored with 10.8.3. The download went well. Although I did not do much before using Spectraview, everything looked fine, browsers reloaded tabs, email was there. Spectraview did its thing re-calibrating the monitor and I was very pleased. However on quitting Spectraview the desktop went black, icons for the desktop folders were there but no text was visible. Rebooting did not help. When clicking on menubar items drop down menus were not visible but if you guessed where something was and moused over it, text could be made out and clicked on. In this way I opened System Preferences>Desktop and Screen Saver. I clicked on the box to change the desktop color, the "crayon box" with choices came up but the desktop did not change whatever color was clicked. Similarly the other choices for setting the color did not work. Other software was affected too; opening a browser for example showed a blacked out screen as well. The computer (2009 MacBookPro) was unusable.
I had the 10.7.5 version of my hard drive saved on my bootable SuperDuper back up drive, and reloaded that version. So I am back to 10.7.5 and completely puzzled at what happened. Any ideas would be appreciated since I'd prefer to use 10.8.3 and regain monitor calibration for photo work.
