RIP Grab.app in macOS Catalina 10.15

Posted

I previously kept Grab.app on Mojave 10.14 by simply copying it over from High Sierra 10.13. I prefer the simplicity of Grab over the new Screenshot.app, and I hate the Screenshot adds a drop shadow.

Alas... Grab from High Sierra 10.13 is dead on Catalina 10.15, as Apple did not maintain backward compatibility in AppKit. RIP.

For screen shots “my way”, see my Touch Bar Quick Action (Automator script), which uses the screencapture command line. You can even use Automator to create your own .app that leverages the command line!
