What is apsd on Mac?
By Junaid, maker of Taskglass · Last reviewed
Keeps a connection to Apple's push notification service so apps get messages instantly.
apsd is the Apple Push Notification service daemon. It keeps one efficient connection open to Apple's servers so that messages, notifications and iCloud changes can be pushed to your Mac right away, instead of every app checking constantly. Having it connected to Apple's servers is normal.
