Hi Bernhard,

I'm afraid this is known macOS sandboxing behavior. The correct way to fix this is to provide a dmg instead of a zip file which forces users to move the app bundle. We should make the macOS-only bundle only available as dmg. But we can't really do that for the AIO bundle because dmgs are not supported on Windows/Linux.

I'll take care of the dmg packaging in the next couple of days.

Best, Fabio

Dear all,

I downloaded http://files.squeak.org/5.2alpha/Squeak5.2alpha-18019-64bit/Squeak5.2alpha-1..., extracted it and double-clicked it. The Squeak window opens but an error message appears:

"Squeak cannot write to the changes file named /private/var/folders/.../Squeak5.2alpha-18019-64bit.changes. Please check you have write permission for this file. You won't be able to save this image correctly until you fix this."

I am on on macOS Sierra Version 10.12.6 (16G1314).

I can reproduce it every time. When I move the extracted .app to another folder before double-clicking it, the error does not happen. However, I only found that out by chance. Real newbies might not be so lucky.

This should work, i.e. the copying to a different folder should not be necessary, right?

Thank you for giving me something to test. ;-)

Cheers, Bernhard
