In that case, I really wonder what's going on.
Can you give me the output of

ls -le@ Squeak6.0-22101-64bit-All-in-One.app/Contents/MacOS/Squeak
xattr -l Squeak6.0-22101-64bit-All-in-One.app/Contents/MacOS/Squeak 

xattr -l $PATH_OF_THE_DOWNLOADED_THING

please?

Apple is scarce on any usable stuff lately…

you should not, if you moved stuff, macOS should have disabled translocation -.-

Lapcatsoftware has old info:
	https://lapcatsoftware.com/articles/app-translocation.html

Here's someone avoiding translocation via some exploit, hence not recommendable:

Forum says signing the dmg or bundle helps (https://developer.apple.com/forums/thread/133743):

Right.
"

We probably have to be tighter in stuff, I just found a "howto":

- https://developer.apple.com/forums/thread/701514#701514021 (for signing or so…)


:( yay more work.
