PictureMe3, the new version of PictureMe Pro, will be Catalina compatible. All previous versions are not compatible with Catalina, due to a bug in Catalina itself, created by Apple. We have verified PictureMe3 to function on Catalina 10.15.3, which is currently in beta. We expect Apple will release the free update to MacOS 10.15.3 in Januari 2020.
If you have purchased PictureMe Pro since October 2019, you can request a “redeem” code for PictureMe3, by sending an email with a copy of your invoice from Apple to support@AppForce.One, with the request for a code for PictureMe3.
