Why Mac Applications Stuck on Verifying

After successfully install GIMP and LibreOffice on my new Mac Mini Late 2012 running Yosemite, I have problems to launch them. GIMP is very slow to open while LibreOffice stuck on verifying forever.

I follow suggestions on 2.8.2 very slow to launch on OS X 10.6.8 on GIMP on OS X suggest to turn off network. It does help to speed up GIMP but LibreOffice.

Turn Off Gatekeeper for First-Time Launch

After reinstall them several times, it seems you have to Allow applications downloaded from “Anywhere” in Security & Privacy for first-time launch. No need to disable network. Fix the “App can’t be opened because it is from an unidentified developer” Error in Mac OS X on OSX Daily provides a step-by-step instruction.

After launching successfully, you may switch back to “Mac App Store and identified developers” to keep you safe. They will be fine.

I think it is related to the Verifying process in Yosemite which stops opening GIMP and LibreOffice.

Update on 2017/5/17

On macOS Sierra, right click on the installer and choose [Open With] → [Installer (default)]. A dialog with [open] button will be launch. Now you may bypass Gatekeeper.

Thoughts

These applications can’t be opened because they are from an unidentified developer. But even choose to ignore warning, I still cannot launch them. Sometimes, they just stuck on verifying without any warning dialog. It is very confusing.

Moving from OpenSuSE to Yosemite is not that easy to me. Seems there are lots to learn on Mac way.
