Borealis

Install Borealis on macOS

For Macs with Apple silicon (M1 or newer). There is no build for Intel Macs; you can build one from the source.

Download Borealis_1.4.0_aarch64.dmg

Install

  1. Open Borealis_1.4.0_aarch64.dmg and drag Borealis to Applications.
  2. Double-click Borealis in Applications. The first time, macOS asks whether to open an app downloaded from the internet: click Open.

Borealis is signed with an Apple Developer ID and notarised by Apple, so there is no right-click or Privacy & Security step.

Borealis 1.3.0 is the first notarised version. If macOS will not open an older copy, right-click it and choose Open, or click Open Anyway in System Settings > Privacy & Security. Updating to 1.4.0 ends this.

Update

Download the new .dmg and drag Borealis to Applications again, replacing the old copy. Your characters, content and settings stay. macOS may ask once more whether to open it, as above.

Where your files are

Characters, content and settings are in ~/Library/Application Support/app.borealis. Deleting the app does not delete that folder.
