How to Hide an Update in the Mac App Store
Although you can hide and unhide apps in your App Store purchase list, it turns out that hiding an app in the App Store purchase list does not hide the app in the updates list! I honestly canβt figure out the benefit of hiding an app in the App Store. The list of your purchased appsβa misnomer, as the list includes free appsβis practically unusable anyway: you can neither sort nor search the list. Maddeningly, the Mac App Store sorts your purchased apps by date of first install rather than by name, so itβs difficult even to scan the list manually to find a specific app.

You can clear the Updates list in the Mac App Store by deleting some cache files on disk, but thatβs at best a momentary solution. The unwanted update will return eventually, or immediately if you use the Reload Page (βR) command.
A more lasting solution is, counterintuitively, to install the update. The trick is that you can keep more than one copy of a Mac App Store app on disk.
I wonder how long you can keep using the old version. You wonβt be able to download it again. You can save a backup, but as some point a certificate will expire or youβll get a new Mac and need a new receipt file. In theory, the store should be able to fetch one for you, but I wouldnβt rely on that long-term.
