Adding a note: BB (MacOS) cannot complete large downloads of .dmg installer files (and some others).
When running latest versions of Brave Browser (during the last 3 weeks of June 2025), MacOS 14.7.6 Sonoma. (Writing, here, w iPhone - no access to BB (MacOS) version numbers.)
I did not post a bug report; simply switched to Firefox, in order to get downloads work completed.
UPDATE - Note to self: there is another BB (MacOS) download problem:
‘No way to enable downloads from certain sources? [MacOS]’
