Have you had the chance to test the autoupdate mechanism?
Another doubt that comes to my mind is: have you tested that when using the cloud editor the tools install is performed successfully? (selecting the correct macos arm64 tool if present)?

[Xayton]

The tests were good:

• The auto-update mechanism works correctly. The tests found no issues (but an opportunity for improvement).
• The tools installation was successful: the arm64 version of the executable will try to download the "closes" version, so arm64 if available, or amd64 otherwise. In both cases the download works.
