A mate has an early 2010 MB Pro running Mountain Lion where, after startup, the desktop loads but freezes thereafter until the lid is closed and reopened. Menus won't drop down from the menu bar or, if they do, no command can be selected. Nothing will launch from the Dock and "magnification" does not occur.
I've Googled the issue and there seem to be many lid related problems (one Apple Community topic is 9 pages!) although none really match this one. The fact that closing and reopening the lid solves the problem suggests that it might be a sleep issue. I've fiddled a bit with the settings in the Energy saver Preference, reset the PRAM, scratched my head, all to no avail. The aforementioned Community topic discusses hibernation interval with all sorts of Terminal commands to change it but I'm not inclined to experiment (i.e. expert enough to clean up the potential mess if I did!).
Simply shutting and reopening the lid works every time and is not a big deal but it would be nice if the thing worked properly. Does anyone have any suggestions?
