In your previous post: Mac Editor Crash, I’ve described how running UE4.14 on an iMac (27-inch, Mid 2011) that is listed as not supporting Metal may be the cause of your crashes. However, this is not definitive.
Since I am unable to reproduce the crash on our test machine, would you be willing to migrate the Blueprint in question along with it’s associated files to a blank project and provide a copy for us to test? If so, please provide a link to your zipped file on dropbox or Google drive, etc. to me on our .
