Can’t open the downloaded package on iMac

[David Cole]

Various sources recommend DisplayCAL, so I’ve been trying to download it (to use with the latest Calibrite ColourChecker Pro – nee x-Rite), both on my iMac, and on my Dell Windows 10 PC. I have now got it onto my Windows PC, but not on my iMac.  For the iMac, I’ve tried using different mirrors through Source Forge, but the programme package either just doesn’t appear in my downloads, or it does but if I try to open it I get the message:

“DisplayCAL-3.8.9.3 (2).pkg” cannot be opened because it is from an unidentified developer..

Does anyone have any ideas how I might overcome this, please?

OS settings security, allow apps from app store and other developers (not only from app store)
