No update in App Store for FCPX 10.3.1
on my iMac (late 2015) the latest update (10.4) for FCPX doesn't appear but on my MacBook Pro (early 2011) it does... Why can't I update? Both computers are up to date with everything, running on OS Sierra 10.12.6...
iMac with Retina 5K display, macOS Sierra (10.12.6)
