hi it's 2014 how can i play beyond on a mac computer thanks
Your best bet is probably using the Mac variation of Wine (a Windows emulator) or dual-booting into Windows itself somehow.
The above is probably the best bet.. Although I am not sure if there are any kind of emulators for Mac.

...Or just buy a real PC. It's 2014, after all.

I run Windows 8.1 on my Macbook Pro through VirtualBox without any problem, it's not as optimal compared to running on a PC but BYOND isn't really that strenuous so you shouldn't have any problems.
This is the 1990s signing in.
Use Windows 95.
Thanks lulz
