Photoshop Elements 11 crashes on MacOS 10.14

Several people have reported that Apple have caused these problems with their latest update. There is always a compatibility risk when updating Mac OS on computers running older software and plug-ins.

Go to Privacy settings in System Preferences and if the Elements Editor is listed you may be able to authorize it.

Alternatively consider upgrading to PSE 2019

Don’t forget Black Friday sales that are coming. There are normally good discounts on Elements. You can get the free trial of PSE 2019 right away. Go to the link at the bottom of this page. If it runs fine there is no need to re-install. Simply use the serial number from disk or key card.
