Sublime Text opens as UNREGISTERED when using MacBook Pro as AirPlay 2 speaker

[fheidenreich]

Description of the bug

Sublime Text opens as UNREGISTERED when using an MacBook Pro M1 as an AirPlay 2 speaker.

This happens when Sublime Text is opened while the device is being used as an AirPlay target. Stopping the stream and re-opening Sublime Text opens it in registered mode again.

It seems to be related to the unique identifier Sublime Text is using to encrypt the license key.

This blog post might shed some light into this issue:

Steps to reproduce

1. Start streaming to a MacBook Pro M1 via AirPlay.
2. Open Sublime Text.
3. Note the UNREGISTERED state of the application (and after some save operations a corresponding dialog to appear).

Expected behavior

Start in REGISTERED mode even if MacBook Pro M1 is used as an AirPlay target.

Actual behavior

Starts in UNREGISTERED mode if MacBook Pro M1 is used as an AirPlay target.

Here is some new sample code from Apple that also works when AirPlay 2 is used:

Most likely caused by #5144 (comment). As a workaround, you can use plaint text license in ~/Library/Application Support/Sublime Text/Local/License.sublime_license.

Thanks! It's License.sublime_license (notice the underscore).

Build 4135 now defaults to using the serial number instead of the mac address to encrypt the license key on disk.
