Hi, I've been lurking on this thread for a little while. I'm a El Captain (against my will) Mac user. I've been locked out of FH since my laptop was updated. I followed the Mac/Linux Setup steps carefully, checked for duplicate files and all that. I encountered the same problem after installing, Wine tells me theres been an error that forces it to close.
I have xquartz installed.
I don't actually have the options to install 1.8.2 OR 1.9.12 versions so I skipped that. I went straight to installing d3dx9.
I ran the program and got the error message (I ignored it), but FH OPENED! I can't tell you for sure it worked because I installed d3dx9, but thats the only thing I did differently this run.
Ha, now I just have to connect to the front server! Wish me luck, I hope this helps other users.
