So, inconveniently, I uninstalled the homebrew-installed subversion and checked out a new copy using the system svn.
(On the flip-side, not having to manually run the UE4-included svn binary from the shell after each point update to re-cache my svn password will be a welcome change).
Every once in awhile clicking the "Save" button from any window (or trying to quit the editor) (or trying to check in to source control) will pop up a dialog saying Updating file(s) source control status... This software consists of contributions made by many people; see the NOTICE file for more information.
Selecting main menu items from the app-level menu does nothing. :-( Since I have Xcode installed, and 4.9.0 uses the system subversion on Mac when present, here's the system svn info: $ svn --version svn, version 1.7.19 (r1643991) compiled Jun 17 2015, Copyright (C) 2014 The Apache Software Foundation.
After I did all that, I could launch the editor and source control would connect. I was able to go about 2 hours without it happening once. Hello Clean Cut, Thank you for reporting this issue.
