I noticed over the weekend that the Add-Ons were all showing up as "Coming Soon" on my Mac, but worked fine on Windows.  There are screen shots showing this in other threads, and I've posted a few of my own.  With the release of the Vaulters Expansion, it is also showing as "Not Mac Compatible" in the Steam client.  In game, I get the same "Coming Soon" highlight over the check box on the Expansion pane.  This is the spot where I can Enable/Disable it on Windows.

Yes, I've tried the "uninstall and reinstall" option which seems to have been the only suggestion from the Devs so far.  As expected, it did not work.  Either Valve needs to fix something on their side or can Amplitude check the "Yes this works on Mac" option so Steam updates accordingly?  Please and Thank You.

Hi there. I'm also gaming on a Mac and experiencing this exact same issue. I can get the Vaulters expansion to work, but all the check boxes for add-ons just say 'coming soon' when moused over, which is a shame as I only signed up to Games2gether to get the latest content...

After uninstalling and re-installing, I have to say that the Vaulter DLC is working fine for me. But the rest is still locked on "soon".

There was a patch just rolled out that fixed access to the Vaulters DLC but the Add-Ons are all still in a "Coming Soon" state.

I'm assuming herein the problem lie:

Windows PC:

Mac:

Same Problem here. All Add-Ons are just labelled "Coming Soon". Looking forward to a fix

As of this morning, the Add-Ons are working EXCEPT for the "Digital Deluxe Upgrade" - which contains the Pathfinder heroes and the Alternate Hero Ship skins.  At least, that is the difference between the DLC on my Windows and my Mac.

And they found the final check box - everything was working on the Mac again as of this post.

I confirm, I had the same issue and now it's "gone", everything seems to be working so far.
