macOS update logic needs improving

[Laura Smith]

Thank you for the recent efforts to bring macOS/iOS up to date.

However there is a little bit of a problem with the logic for your macOS App Store updates.

The update downloads fine, and *appears* to install, but the App Store app continues to show the update as available and installed.

Further investigation shows that if Wireguard is running and/or open, the app will not actually be updated (App Store will roll back to the existing version).

If Wireguard is quit, then the update will install OK.

So you probably need to add some logic somewhere to detect and deal with open/running Wireguard (e.g. prompt user to exit).
