I’m having this issue as well.
Big supporter of WC3 here for over 2 decades. Really disappointed that the support for Mac across all Blizzard products (D4?) has deteriorated over the years.
That being said, I’m hopeful that the 30th anniversary effort results in some increased awareness as to the Mac player base that exists and that there still is an incentive for Microsoft/Blizzard to now support this dedicated and meaningful group of players.
Just hoping in I guess, I made all my friends buy the game for the 2.0 update so we can all play together, they all did, turns out my Mac can’t run it…lmao.
I had to make it work using Parallels but I’m not paying that to only play WC3.
It would, at least for me, make it bearable if we had the game on GeForce Now at least, I use that to play every other game, pretty much all Battle.net games are there but not this. Guess making it difficult is the way to go…
Same here 
‘Hello! Looks like you’re enjoying the discussion, but you haven’t signed up for an account yet.’ — just wanted to post to say that: 1) I’m NOT enjoying the discussion lol, 2) cause I have the same problem on my Mac (T_T). When will this get fixed…
Any news on this?
Yeah mate still broken. Grubby has spoken about it in his latest video so that’s all our cards played now. All up to blizz to make this right
Disclaimer: I have zero affiliation with Blizzard
Did a bit a digging on what is publicly available for those similarly technically minded. This ticket is marked SSE, probably server-sent event error. It is a denial of all Mac origin requests on both the battle.net and SPS APIs (public info here). I guess this means a malformed object in the packet… basically the authentication system for all Mac installs is broken, probably client side.
The VPN error suggests a region mismatch so must be a bit of a nightmare in the loop.
Perhaps some very basic tests in the future before pushing to prod please?
I dont think ‘tout’ is the right word for it…
They just have to keep it going enough to live up to a promise made by blizzard 10 years ago…
still doesnt work
any update?
it was working fine for me on pc the last few days.
Only now it just started giving me the error.
they are doing a maintenance. Game is down atm
updating 
… arrgh same error
I believe thats the “emergency maintenance” thats going on
had a different error for the first launch after updating (2:23200 iirc) but now back to 6:9, this is ridiculous
The maintenance is still going on. Any issues encountered will likely be due to it.
Now game actually opens. However, I can’t enter Multiplayer. Anyone else?
it opened!
It’d wait for the maintenance to end before doing very much. Features can up and down.
Oh I didn’t realize there’s maintenance going on. Do you know the ETA for it end?
it works! I can join games
