My technique:

1) I have a folder I've made, /Applications/Squeak

2) I copy the all-in-one app bundle out of .dmg file and into this 
directory.

3) I then ctrl-click or right-click on the app bundle and choose 'open' 
to get around the Gatekeeper dialog on first launch.

This is how It Works For Me, on 10.13.6 and 10.15.x and 12.4 and other 
macOS versions I use.  (I have some professional background in this;  
I've had to coach entire orgs on `xattr -d com.apple.quarantine`, 
right-click to open, "allow access to Documents folder" prompts [PPPC], 
etc.  It's a hassle.)

It would be possible to build the .dmg with a pretty background graphic 
which encourages users to drag-n-drop the .app into /Applications.  Very 
typical of apps to be bundled this way on macOS.

There was some discussion on the list a few years back about app 
sandboxing and how it impacts the user experience around the all-in-one 
on macOS.  I'm not sure anything conclusive was discovered.  One strange 
effect is that "Save as new version" saves the image as a new version 
/inside the app bundle/.  Perhaps having `FileDirectory default` return 
the sandbox directory would be worth considering, but those sandbox 
directories are also ... basically annoying.

Thanks,
Tim J
