Private alpha

Apply for the mPLAY Private Alpha

mPLAY is entering a limited private alpha for macOS. This early test is intended for technically comfortable users who can provide useful feedback about playback, menus, subtitles, audio, performance, and unusual disc formats. Alpha builds are experimental and may crash, fail to play certain media, or change behavior between releases.

Distribution

This alpha will be distributed directly by mPLAY.me outside the Mac App Store. Future builds are intended to be Developer ID signed and notarized before tester distribution. The alpha has not been reviewed through Apple TestFlight or the Mac App Store.

Access Verification

During alpha testing, mPLAY requires an active internet connection when launching the app. The app will contact mPLAY.me to verify that alpha access is granted for the current tester/build and to help prevent unauthorized sharing of private alpha builds. This check is part of the alpha program and may be changed or removed in later releases.

Experimental Components

Some Blu-ray menu features currently rely on bundled experimental compatibility components. These are included for testing only and may be changed or removed in future builds.

Legal Media

Please only test with media you legally own or are otherwise authorized to use. Do not upload, submit, or redistribute copyrighted disc images, movie files, or other protected media.
