Steam achievements not working on mac

I am using version 4.7.

Achievements work fine on PC, when passing the exact same project to mac (as in copy the project folder) the achievements don’t work.

We are calling the (Cache Achievements)->(Write achievement Progress).

The cache achievements node to be resolving successfully, if we hook a print node to the “on success” arrow it fires, so i guess the problem is with “Write achievement Progress”.

Any help would be greatly appreciated.

After 2 days on this our artist figured it out because he read things with way more caution then me.

We were missing a lib “libsteam_api.dylib” on mac, i assumed since it does things automatically for windows it would be the same for mac.

If any 1 else runs in to this problem follow this link: Online Subsystem Steam | Unreal Engine Documentation.

The solution is right next to the big yellow rectangle, it is easy to miss.
