Windows Only

That is correct. Currently the Bardo Stations Training Orbs run on windows only.

Does that mean they will not run on my Mac?

Yes they will not run on the Mac operating system.

However, if you are cleaver, you can wrap the Orbs in wine (the program not the beverage) and run the Orbs in wine on your Mac.

Kind of a technicality. But, wrapping in wine is not trivial. So for most people the answer is no. For people that are good with software, or have a friend that is good with software, they will run in a wine wrapper.

Since we don't know much about Mac computers or the wine program, we will be little help in this process and will not be able to support your efforts in this regard.

So, Short answer is Windows Only
