10.15.7 Installs aliases instead of programs into the application folder

I have a new MacBook running 10.15.7. When I install a non-Apple apps, like DxO PhotoLab 4, BBedit, the installation appears to proceed as normal. But it results in the installed app's ALIAS being put in the applications folder. An attempt to open the app with that results in the app attempting to open from the installation .dmg file. This is bewildering. I've been installing programs on various Mac machines for 20 years and never encountered this before. How do I get my non-Apple apps installed?

After some trial and error, I've fixed the problem. I don't know the exact technical details why, but Catalina does not properly install non-Apple, third-party programs. Whatever permissions changes the Apple crew made in this OS prevents a new program from being dragged from the .dmg installer image file into the applications folder. If it IS dragged in, it becomes an alias file and the program is not actually installed. The solution turned out to be relatively simple:

- Open the .dmg installer

- Drag the program icon to the desktop (not into the applications folder).

- Click it open so the actual install can occur

- Then drag the program from the desktop into the applications folder. That's it.

This effected various programs I was trying to install on my new MacBook Pro including DxO PhotoLab 4, PhotoMechanic 6, Max Bulk Mailer, BBedit and several others. It seems surprising that Apple appears to have not made any effort to inform users about this but also provides no information on how to overcome this maddeningly frustrating barrier to installation anywhere on its website that I could find.

If there is no Finder window showing you to drag & drop the app to the Applications folder, then you maybe those apps require you to double-click the icon on the mounted .dmg volume to run the app's installer.

This makes no sense. You are "clicking it open" which I assume means double-clicking it which is actually running the installer app to create the actual application in the Applications folder along with any other "helper" files it needs to place elsewhere on the system. The only time you drag & drop an item from a mounted .dmg file is when the mounted .dmg opens a Finder window showing instructions to drag & drop the app to the Applications folder. You either drag & drop the file or you double-click on it. You never do both.

I'm glad you were able to install your apps.
