Data Package Error - Restart Loop on Mac
I started MTGA with the BRO set on MacOs, but since the release of "ONE" on 7 July the application start leads to an error: "Data Package Error found. Arena will be booted up to verify data package." After clicking on "ok" what is the only option here, the application starts again and runs into the same error. I attached a screenshot of the error (German version). Technical Support cannot help. Firewall is fine. I have restarted router, Mac, MTGA, Epic Launcher already and deleted and installed the Epic Launcher and MTGA and updated MacOs to the latest version. No solution, still the same error. However, I am still able to play it on my iPad without any error. So what exactly could be the condition that leads to that error?
Original message in German: "Datenpaketfehler entdeckt. Arena wird neu gestartet, um Datenpaket zu verifizieren."
