My daughters Macpro 13" has developed a problem today. We upgraded the operating system last week from leopard to snow lepord to mountain lion. Back up everything did a clean install and reinstalled from backup. Then we had a Apple repair shop install 8 gb of RAM. WE are using MS Word for Mac 2008. Now when she working on a word doc the computer says there is a problem and needs to shut down. Does anyone else have a problem with Word 2008 with Mountain Lion? Thanks.
