Possible Ways to Fix Mac Office 2011 Crashing in Yosemite Supposedly these crashes have been occuring sporadically even back to some Yosemite betas. I went searching for a solution on various forums but only seemed to find other people encountering the same issue. It didn’t matter if I opened a document directly or one of the Office applications, within a few seconds, the Office App would crash. Every time I launched Word, Excel or PowerPoint, the app would crash after a few seconds with an error asking if I wanted to recover my work, reopen the Office app and send the error to Microsoft. Recently, my version of Office for Mac (Office 2011), started crashing on my MacBook Pro.
