I have seen multiple people on multiple forums post about having issues running Toontown Rewritten on their Mac and I am now also having this issue. I recently got a brand new MacBook Pro and every time the game is downloading in the launcher it either gets stuck on the phase_3.5.mf file or the phase_4.mf file and refuses to proceed downloading. If I click out of the launcher, go back in and type in my login information again, instead of resuming the download the game will attempt to start up even though it has not finished downloading and will instantly crash. I have seen solutions consist of using a zip file and I have tried downloading a few and still had no luck. If anybody has a zip file they believe would work or have any other solutions, it would be greatly appreciated!
