The recommended installation method is via Homebrew Cask.
If you plan to use Borg’s mount feature to browse backups, you will need to install macFUSE and Borg’s own tap:
$ brew install --cask macfuse
$ brew install borgbackup/tap/borgbackup-fuse
OR to install Borg without macFUSE/mount feature:
$ brew install borgbackup
Then, as last step install Vorta
$ brew install --cask vorta
If you don’t use Homebrew, you can find releases on our Github page. This will usually work on the latest version of macOS only.
