Open MiniSpace for the first time

macOS will probably warn you the first time. That is expected. Check the download, then open the app once.

Last updated: 10 November 2026. Applies to MiniSpace 0.2.1.

Why macOS warns

This release is ad-hoc signed and not notarized by Apple. It is an indie release made without the Apple Developer Program. macOS says it cannot check the app for malicious software. That does not mean the download is damaged.

Check the download first

Compare the SHA-256 checksum of the DMG you downloaded with the published one. In Terminal:

shasum -a 256 ~/Downloads/MiniSpace-0.2.1-arm64.dmg

The expected value is:

4e6410bca5c63a48e18ffe4c697f171b1ec15f558292e27328c4bec713d9a321

The file size is 137,860,306 bytes. If the value differs, do not open the app. Download it again, or write to [email protected].

Open it

  1. Drag MiniSpace into Applications.
  2. Open it. macOS blocks it the first time. Click Done.
  3. If you trust the download, in Finder go to Applications, Control-click (or right-click) MiniSpace, choose Open, then choose Open again.
  4. If macOS only offers Move to Trash or Done, open System Settings > Privacy & Security, scroll down and choose Open Anyway next to MiniSpace.

You do this once. Apple describes both ways:

What not to do

Do not turn off Gatekeeper or System Integrity Protection. Do not run commands that strip security attributes from apps. MiniSpace never asks you to.

Managed Macs

If your Mac is managed by an organisation, its policy may not allow this app to open at all. MiniSpace cannot promise it will open on every Mac.

Enter your license key

On first open MiniSpace asks for your license key. Paste it and press Verify.

Gumroad shows it in your purchase receipt email and on the download page for your order. If you lose it, use Gumroad's license key lookup with the email you bought with, or write to [email protected].
