CCP has done a lot to help. Yet, just my opinion, they seem to have disappeared of late.
I believe the CCP wine bundle is 2.22(?). They have a dev version that is farther along, but it seems the devs who where supporting the Mac/Linux side have ether died, or given more pressing task. So a lot of the new game features coming out lag up older hardware (not just macOS) and have been causing pains for many of us. I know that when I have a chance to play, having my two accounts in at once use to be smooth, but now have issues every once in awhile. I have to generally close clients and relaunch.
