Hi Norbert, Yes, it gets increasingly difficult to defeat Apple's Gatekeeper from "keeping you safe".
Open a Terminal, cd to the directory where your ImageJ.app lives, and run: sudo chflags -R nouchg ImageJ.app sudo xattr -rd com.apple.quarantine ImageJ.app And then hopefully it will start up when you subsequently launch it. Relevant Image.sc Forum thread: https://forum.image.sc/t/warning-your-imagej-installation-cannot-be-updated-because-it-is-read-only/20333/4 Regards, Curtis P.S. Fiji will soon ship a signed & notarized Fiji.app bundle, to appease Gatekeeper. P.P.S. Wayne: Let me know if you would like a signed & notarized ImageJ.app as well.
