Starting with macOS Catalina, Apple requires apps distributed outside the App Store to be notarized by Apple, which requires a paid developer account. Apps that aren't notarized will show a warning when opened, like the "Apple couldn't verify Pocket Sync" message. You can safely bypass this warning by following these steps:
-
Download the latest release from releases.
-
Double click
Pocket.Sync_X.X.X_universal.dmg
to mount the image. -
Drag
Pocket Sync.app
to theApplications
folder. -
Open the app, resulting in the following message being displayed, "Apple could not verify "Pocket Sync".
Important: This message must be displayed at least once to allow a new option to appear in system settings
-
Open "System Settings" (click in upper left -> click "System Settings").
-
Scroll to "Privacy & Security".
-
Under the Security header, click "Open anyway" next to the message "Pocket Sync was blocked to protect your Mac."
