How do you make a shirt on Roblox when you are on a Mac

Roblox shirts can be made on macs the same way they are made on PCs. Open a template with your favorite photo editing program, create the shirt, log on to Roblox, and upload the shirt. Everything on the Roblox website works the same way on a Mac as it does on a PC, except that you can't play or edit games on a Mac.
