I have installed Python 3.6.8 and am attempting to run QGIS 3.14 on Mac OS 10.15.5. I get this message, which doesn't show in any existing questions I could find: Apple cannot check for malicious software

Should I try an earlier version of QGIS?

Tried 3.10 and got same response.

If you get a malicious software won't install warning for any of these, go to the Apple menu > System Preferences > Security & Privacy > General Tab > Allow Anyway

This will let you install the software.

  • it worked for me! thank you!

From: https://www.kyngchaos.com/software/qgis/ There a simple way to force it to install – right-click the installer file and select Open, this will trigger an extra option in the security warning to install it anyways. Works on an already installed app as well.
