PostCheck 2

Download PostCheck

Since PostCheck hasn't been updated in a while and no longer supports macOS versions later than 10.13.x, I've decided to just offer them as a free download (though donations are welcome).

PostCheck 3 Alpha is really just a test. It's the batch lookup function of the old PostCheck that's been compiled into a standalone app for later versions of macOS. It "works" but it's unsupported, has horrible UI, never even close to finished, etc.

New! PostCheck 3 Alpha 2 — January 1, 2020
Requirements: macOS 10.14 Mojave or later.

PostCheck 2.5 — September 30, 2016
Requirements: Mac OS X 10.9 – 10.13.x.
Not compatible with macOS 10.14 Mojave or later. Apple has removed all support for Address Book plugins.

PostCheck 1.9.2 — November 19, 2009
Requirements: Mac OS X 10.4 – 10.7.x.
