Fixes Magic Arena's broken full screen implementation on macOS

arena-macos-full-screen-fixes.sh

# this forces Arena into full screen mode on startup, set back to 3 to reset
# note that if you go into the Arena "Graphics" preference panel, it will reset all of these
# and you will need to run these commands again
defaults write com.wizards.mtga "Screenmanager Fullscreen mode" -integer 0
defaults write com.wizards.mtga "Screenmanager Resolution Use Native" -integer 0

# you can also replace the long complicated integer bit with any other scaled 16:9
# resolution your system supports.
# to find the scaled resolutions, go to System Preferences --> Display and then
# divide the width by 16 and multiple by 9. on my personal system this ends up
# as 3456 x 1944 (versus the bizarre 1728x1117 it will very temporarily select
# when clicking the full screen option in the client
defaults write com.wizards.mtga "Screenmanager Resolution Width" -integer \
  $(system_profiler SPDisplaysDataType | grep Resolution | cut -c23-26)
defaults write com.wizards.mtga "Screenmanager Resolution Height" -integer \
  $(bc <<< "$(system_profiler SPDisplaysDataType | grep Resolution | cut -c23-26) / 16 * 9")

Deleting the arguing here, especially since it's about the PC version and this gist is about macOS.

I recently found a way to get it to work well on my MBP 13-inch M1 with 2560x1600 native screen resolution. Running the game in native resolution causes some UI elements to be cut off as people have said. In order to get it to run in 16:9 so that you can see everything I added this to the options in Epic Games Launcher:

-force-metal -screen-width 2560 -screen-height 1440

However, as soon as you open the settings menu in game it will mess this up

The fact this is still an issue after so long is absolutely despicable
