App Store updates
App Store apps are managed through Apple's storefront and receipt system. They are usually straightforward, but they only cover apps installed from the App Store.
Homebrew updates
Homebrew updates formulae and casks installed through Homebrew. It is excellent for developer tools and many GUI apps, but it does not manage every app in Applications.
Sparkle updates
Sparkle is common among independent Mac apps. A safe Sparkle path depends on a trusted appcast, archive metadata, signatures, and a version that moves forward.
Vendor-managed updates
Microsoft AutoUpdate, Adobe Creative Cloud, Google updaters, Docker Desktop, and similar tools may be the safest owner for complex app families. A third-party updater should recognize those paths and hand off when needed.
Direct downloads and manual releases
Direct replacements can be safe when the downloaded app preserves bundle identity and signing team, and when a backup exists. Manual release pages should stay visible so the user can inspect the vendor's own instructions.
How macCurrent uses source labels
macCurrent uses source labels to decide whether an app can be updated directly, should be handed to its owner, or needs review before anything changes.
Frequently asked questions
Why do Mac update sources matter?
The source determines which trust checks are available and which installer should own the update.
Can Homebrew update direct-download apps?
Only if the app is actually installed and tracked as a Homebrew cask. Many direct-download apps are outside Homebrew's view.
Should vendor-managed apps be updated manually?
Often yes. If an app family has its own trusted updater, the safest path may be opening that updater instead of replacing app bundles directly.
