What Sparkle does
Sparkle is a popular update framework for Mac apps. It lets apps check appcast feeds, download releases, and replace the installed app when the update is trusted.
Why appcast trust matters
A safe Sparkle update should be delivered over HTTPS, match the expected app identity, and verify against the app's signing or EdDSA update keys.
macCurrent's role
macCurrent uses update-source and trust signals to decide whether a Sparkle-style update can proceed safely or should be reviewed first.
Frequently asked questions
Are Sparkle updates safe?
They can be safe when the feed, signature, app identity, and version direction check out. Unverified or unexpected paths should be reviewed.
Does macCurrent replace Sparkle?
No. macCurrent helps find and judge update paths. Apps may still use Sparkle as their own update mechanism.
