MacUpdater
MacUpdater is a macOS utility from CoreCode Limited that scans installed apps and helps you find and apply available updates.
What is MacUpdater?
MacUpdater is a third-party macOS application published by CoreCode Limited that checks software installed on your Mac for newer versions. It is designed to scan the Applications folder and optionally other locations, show which apps are outdated, and in many cases help download or install updates from the original vendor. The app also supports menu bar operation, periodic background checks, notifications, exclude lists, and configurable scan settings, so users may encounter it as both a normal app and a login item. MacUpdater integrates closely with the local app inventory on a Mac, which is why it may request broad disk visibility to inspect installed software. CoreCode has announced that MacUpdater 3 is unsupported and no longer actively maintained, although the app remains available as free-to-use software with its previous Pro features unlocked. Because of that status, it is best treated as a legitimate but discontinued utility whose update data and future compatibility may become less reliable over time.

Safety overview
Status: Mostly safe
MacUpdater is a legitimate utility from CoreCode Limited, not generally known as malware. However, it inspects installed apps and may request broad file access to perform scans, so it has visibility into your Applications folder and other locations you choose. Its publisher has discontinued support and stopped daily maintenance, which increases the risk of stale update data, broken downloads, or reduced compatibility on newer macOS releases.
Recommendation: Keep it if you still use it to monitor third-party app updates and it works well on your Mac. If you no longer rely on it, or you prefer actively maintained update tools, it is reasonable to remove it. Review any background launch setting before uninstalling so it does not continue starting automatically.
