I have downloaded X-plane from steam to my iMac. I'm also unable to download the North America from steam. I can get to the point where one checks marks the downloadable contents. When I check the box on North America scenery, there is no way to check on the link to download. The screen informs me that I already own the file. I tried to get technical support and was referred to Aerosoft. OK, I created an account there and submitted my problem. So far, no reply. Has anyone figured out how to download the scenery to the MAC from steam? Thanks and regards, Rafael
