This is the "helpful" message one now gets when trying to install an unsigned app on a Mac. Here are two workarounds*: 1. Re-enable Gatekeeper "Install from Anywhere" option via `sudo spctl --master-disable` 2. Unquarantine Pharo only via `sudo xattr -r -d com.apple.quarantine /Applications/Pharo.app` * https://apple.stackexchange.com/questions/243687/allow-applications-download... ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html
