I'm trying to update Airmail to the latest version on my MacBook with El-Capitan 10.11.6 (15G31).
When I go under App Store > Updates, I see no new updates. When I search for the Airmail app I see that I am 1 version behind. If I click the "update" button, all I see is the progress indicator spinning for hours.
I've tried:
- Restarting my Mac
- Clearing App Store cookies
- "Reset Application" in App Store
- Running
killall -KILL storeagent
(which saysNo matching processes belonging to you were found
) - Running Disk Utility to check for any problems (none found)
How can I restore my ability to update apps?
