RCT Deluxe and Triple Thrill for Mac

[redbirds5]

Hello,

Newbie here. Also not the most technical so I apologize if some of my verbiage is off.

I downloaded OpenRCT2 on Mac. It's just the base version of RCT2. I'd like to expand it to include the Triple Thrill expansion and import RCT1 Deluxe for the additional features/parks.

Is it possible to do this on a Mac? I believe I need the original files for Triple Thrill and RCT1 Deluxe but those are only available for Windows on Steam, so I'm not sure what options, if any, I have to expand the base version of RCT2 on Mac.

Any help would be greatly appreciated!
