Homebrew casks are powerful but partial
Homebrew is excellent for developer tools and many GUI apps, but it only sees apps installed or managed by Homebrew. App Store apps and many vendor updaters live elsewhere.
Why source labels matter
A Mac app update workflow should tell you whether an app is managed by Homebrew, the App Store, Sparkle, a vendor tool, or a direct download so you know which update path is appropriate.
How macCurrent uses this signal
macCurrent treats Homebrew as one source in a broader app update map, then helps decide whether an update is safe, needs review, or should be handed off.
Frequently asked questions
Does Homebrew update App Store apps?
No. Homebrew manages formulae and casks installed through Homebrew. App Store apps update through Apple's App Store.
Should I use Homebrew or macCurrent?
They solve different parts of the problem. Homebrew updates Homebrew-managed software; macCurrent helps review update status across multiple Mac app sources.
