Stop App Store prompting for specific system update I have a Brother MFC printer, and installed the latest drivers from the Brother website. All is good, everything works.

The App Store now prompts me that there is an update available: Brother Printer Software Update 2.10. This looks like an Apple package, and isn't the same as the Brother one.

With this installed I can't print, and it doesn't even think the printer has a scanner attached. After deleting the printer, re-installing the Brother package, and re-adding the printer it's all working again.

It appears in the top Software Update section of the Updates page, not in the section below for regular app updates.

Is there a way to specifically block this one update? I know app updates have been discussed in other questions, this isn't it.

I'm on 10.8.2
Turns out that if you click on "More Info" and expand the update fully, you can then right-click on it and choose "Ignore Update".
