Every Helmsman release is signed with an Apple Developer ID and notarized by Apple, which is why Gatekeeper opens it on first launch without a warning. You do not have to take this page's word for either claim. The two commands below let you check the signature, the notarization, and the download's integrity from your own Mac.
Check the signature and notarization
Run this against the app in your Applications folder:
spctl -a -vv /Applications/Helmsman.appYou should see:
/Applications/Helmsman.app: accepted
source=Notarized Developer ID accepted means Gatekeeper trusts the app, and
source=Notarized Developer ID confirms Apple notarized this exact build under
Helmsman's Developer ID. Together they prove the app is the one we signed and Apple cleared,
not something altered on its way to you.
Check the download integrity
From the folder where the disk image landed, hash it:
shasum -a 256 helmsman-0.7.0-beta.2.dmgThe result should match this value exactly:
08d881dcbff946f3e27acd12c4149cc9fde90b5f697d9757559371f0c464255e helmsman-0.7.0-beta.2.dmg
If the hash matches, the file you downloaded is byte for byte the one we published. The value
on this page is computed from the exact notarized build we ship and is updated with every
release, so it always describes the current version, v0.7.0-beta.2.
The current build's version, size, and system requirements live on the download page.
