Mac Linux without the "." it works and pick-up the right box.

In either case with the "." and without the "." in the version number under Linux it recovers the expected box which shall be the "v2025.07.24" or "v20250724"

Expected behavior

Both environment shall use the "v20250724" version box

Actual behavior

Under Mac compare to Linux the version pulled by vagrant is the "v2025.07.21" with the exact same metadata.json file which doesn't make sense.

We have been testing while removing the "." in or version number and than Mac pick-up the correct expected box
