If you’re a Mac user who regularly uses Adobe Photoshop or Lightroom Classic CC, we don’t recommend updating your computer to macOS Catalina just yet. Even though the new operating system has been in beta for months, updating your Mac today will lead to a few annoying issues that you might want to wait for Adobe to iron out.
Apple officially released macOS Catalina yesterday, and neither Adobe Lightroom Classic nor Adobe Photoshop CC were fully prepared to handle the new operating system as of this writing. According to Adobe’s macOS compatibility pages for both Photoshop and Lightroom, the latest version of these apps “work with macOS 10.15 (Catalina) but have … known compatibility issues.”
If you are a “professional” user of either app, you’d have to be insane to update to macOS Catalina until Adobe pulls its head out of its posterior and fixes these issues.
