MacOS On-Board / Pre-Installed Apps . . .

Hello,

I started out trying to tidy up and organize the Applications folder by creating subdirs for related apps, and moving each app into the appropriate subdir. Downloaded apps behave well and move when moved, or, at most, ask for administrator authorization. So why do some apps move without a peep while others ask for administrator authorization?

Next, MacOS’s on-board / pre-installed apps just won’t move from the Applications folder to a subdir within it. Yes, you can copy and then delete (which I don’t want to do) but you can’t move a MacOS app. So, first, why are MacOS apps ‘immovable objects’? And second, is there any way to (irresistably) force them to move within Finder? (I know I could do a sudo mv on the command-line.)

Thanks.
