2015 maxed out MBP running 10.12.2. Recently developed a problem of randomly loosing preferences for apps. I'll start it up, launch safari, and my preferences, toolbar, etc., have all reverted to the default configuration. I thought maybe it was limited to Safari, but now it's affecting my Adobe products as well. Just launched lightroom to a default layout. Also, i've noticed iFFmpeg keeps forgetting it's license info... never done that before. Safari was the only recent change other than normal Office and Adobe CC updates. Any ideas would be appreciated!
