Build Swift on an Amazon Linux AMI
#
# Notes:
#
# I used the following AMI:
# "Amazon Linux AMI 2015.09.1 (HVM), SSD Volume Type - ami-60b6c60a"
# Running on AMI: amzn-ami-hvm-2015.09.1.x86_64-gp2 (ami-60b6c60a)
#
# You probably want to use an instance type with a large amount of memory. My first
# attempt was with a c4.2xlarge but it rant out of memory without using -j option to
# limit the parallel build.

Instructions on how to install Magic the Gathering Arena on macOS with Retina support.

Installing MTGA on macOS using Wine, and making it look pretty!

The following instructions are heavily inspired by /u/uhohohdear. I modified uhohohdear's instructions and then added support for Retina/HiDPI displays and instructions about how to update MTGA.

Dependencies

  1. Your macOS/OS X version must be 10.8 or greater
  2. Your Mac must support OpenGL 4.0 or greater (you can find out whether it does here)
  3. You must download the Magic the Gathering Arena Windows executable
  4. You must download a custom Wineskin wrapper [mirror]
