Unity hangs on Play because of app/company name

In Unity 4.2.2f1 (using older version as too many issues with 4.3.x), OSX Mavericks

My app for no discernible reason started hanging every time I hit play. I restarted Unity, then the computer, then reimported all assets, then deleted everything from the project directory except for the Assets folder and it started working again. So I re-entered the player settings/quality setting etc. and … it started hanging every time on hitting Play. No console output, no log output, Unity just hangs as has to be force-closed

Eventually tracked this down to being caused by the company and product name in player settings. If I set these to what I used to have them then I get the hangs. if I change either to something slightly different then the app plays just fine.

Is Unity caching something, somewhere, based on a company/product combination key that’s become corrupt? Any other ideas what could be causing this behavior?

Not sure what’s causing the specific problem your seeing, but there’s a thread about people having issues with Unity and Mavericks:

If you think you’ve found something specific, file a bug report and hope it helps the dev’s figure out what’s going on

Thanks for the reply. That thread is for 4.3 Unity so not related to the issue i’m seeing. I’ve submitted a bug report but without any crash logs or errors showing anywhere not much to go on - the issue must be related to how Unity prepares the app for running in the Editor.
