MacOS – Stop App Store prompting for specific system update

Hamrick VueScan

This is a "Swiss-Army-knife" scanning application that supports hundreds and hundreds of makes and models of scanners, even many obsolete ones which don't have direct Mac OS X support.

Download and evaluate the trial version.

I use it with my Brother MFC-6490CW, which does have Mac OS X drivers, but I'd rather use VueScan than use the Brother or Apple scanning software. Although VueScan has TWAIN support, I use it as a stand-alone scanning solution to output PDF, TIFF and JPEG.

While I'm not abosultely sure, how achieved my result, but after a reboot the update for one app-store app is gone now. What I did:

• the following is tested on old Blackmagic Disk Speed Test.app (free from appstore), before my tests the app-store showing an available update for it.
• Right click on app, select Show package contents
• go to "Contents"

• Move the following files and folders to some backup place

  • _MASReceipt (folder)

• reboot

If that doesn't work, remove these additional items from the package contents: - _CodeSignature (folder) - CodeResources (alias)

Maybe it is not enough, (in my tests i did the following too), try:

• Go to Library (alt-click on Finder's Go menu, select Library)
• Caches
• move com.apple.appstore folder somewhere else(backup location)
• reboot

After the above steps, the AppStore don't showing the available update for the "Blackmagic Disk Speed Test.app".

Warning: all the above is tested only in one app, needs more testing, it is absolutely without any warranty and don't blame me when your computer will burns, gets grabbed by aliens or anything other...
