How to avoid MacOS message "Verifying Affinity Photo.app" (was: DavidRB)

[DavidRB]

When I click on the Affinity icon, I get a little box stating verifying "Affinity Photo app. It then presents me with a dialogue boxasking me whether I want open iot. I have attached a image of these two things. Can you mtell me how I can stop this happening? Many thanks, DavidRB

Welcome to the Serif Affinity forums, David.

I'm not a Mac user, so I'm largely guessing here. But the message in the larger box says you're invoking Photo from a .dmg file. That's a disk image file, and is the file from which you would install Photo, not the file you would use to run Photo.

I don't think you have the application properly installed. Or, perhaps, not really installed at all, yet. You can find more info on installing the app on MacOS in this post:

No, it doesn't play a role if an app is installed via a .dmg or .zip file etc. here in this case. The fact is more that the app which is installed into /Applications does stem from a none Apple source (is not from the AppStore) and thus it is then treated security wise different. So even the app may have installed fine, the first time you start it up, the OS will indicate that and ask for security reasons for your verification to open that app. - It's only verified on the first startup after installation, further executions don't need then any verifications.

Judging from the screenshot, that is almost certainly the problem. It clearly says that @DavidRB is attempting to open the app directly from the mounted disk image "affinity-photo-1.8.4.dmg."

What he should be doing instead is to double-click on that dmg file in Finder, which will automatically launch the Mac installer app & install the app the disk image contains in the Applications folder.

EDIT: If he has already done that then he should just eject the dmg because there is no reason to keep it mounted since it has already done its job.
