Whenever I try to open OmniGraffle 6 on my retina MacBook Pro, it crashes. I have sent through the crash report and also contacted support@omnigroup.com.
It was working fine until last week. OmniGraffle Professional 5.4.4 works fine on the same MacBook.
Very similar problem for with Omnigraffle 6.1, OS X 10.10.1, and a MacBook Pro. I also submitted a bug report via the crash reporter and is tracked via [OG #1276230]
Still have similar problem with Omnigraffle 6.1.1 and OS X 10.10.1. Not the exact same crash so I opened another ticket and it’s being tracked via [OG #1288417]
