Issues with mac os big sur

right away at menu the video is lagging then going into blacksmith a bit choppy even opening up the inventory there is delay. Game play is terribly slow. I know it’s not my internet because on my playstation it works fine. But, since I upgraded to mac os big sur. the game response is down right slow. Any thoughts of fixing or do I need to wait for diablo update?

what did you expect? Apple has long stopped properly testing their software releases and they are garbage.

I am having the same problem on a Mac mini m1.

Ooops ! wrong answer ! Do you really think that Apple or Microsoft or other companies really have to adjust their products to suit a game ? The real problem is the games manufacturers that NEED to ADJUST their products to follow the market !

Try setting the Diablo to Open in Low Resolution using the Finder and Get Info. Works wonders for performance.

nah mate. Apple’s software testing is atrocious.

I have a Mac mini M1 and am having no problems whatsoever. Nice and snappy at high res. Many people are having problems with their mouse and keyboard because Apple uses Bluetooth Low Energy, not Bluetooth, and if your device doesn’t do this correctly then it’ll disconnect. Of course, the same Broadcom module also does WiFi, so when your mouse disconnects so does the Internet.

They need to make Diablo native for the M1, it should run much smoother then.


Unfortunately that’s unlikely to happen unless our sole Mac dev gets time to transition D3 to the Metal graphics API. OpenGL is supported only via Intel binaries and is deprecated and almost not supported at all in modern drivers.

I wouldn’t mind seeing Diablo 3 transitioned to Metal, but that would mean 10.12.6 is the minimum regardless of the XCode targeting when making the client build. Still, it’d probably fix a lot of the AMD issues the game has.

I’m having the same issue with TBC classic. Since updating MacOS 11.5.1, my game play is horrible and downright unplayable.

Something just dawned on me. Anyone who buys a new Mac will have Big Sur (11.0.n) installed by default. They are unlikely to want to, or successfully downgrade.

Blizzard needs to pull their finger out and fix the game to run with current release MacOS version.

Can you image the disappointment someone feels when they buy the game for their new Mac only to have the terrible experience? What a let down.

Sadly, Blizzards refund policy appears to be somewhat opaque. I can only speak for the Australian experience. I found this page… [oh yea, we cant post links in here :roll_eyes:] Google for “Business Insider refund Blizzard” and it should hopefully pop up. I am not a lawyer.

Australian consumers who have purchased the game for use on a Mac are very likely to be eligible for a full refund under the Australian Consumer law. There is a good synopsis here. [oh yea, again, we cant post links in here :roll_eyes:] Google for “australian consumer guarantee” and jump on the ACCC website.

… the following consumer guarantees on products and services apply.
Products must be of acceptable quality, that is:

  • safe, lasting, with no faults
  • look acceptable
  • do all the things someone would normally expect them to do.

To be frank, the current circumstances seem to not pass the 2nd or 3rd bullet points above. Under the law, people in Australia who have purchased the game could be entitled to a full refund because is no longer doing the things I expect it to.

You need to convert the link to preformatted text for it to be acceptable to the forum.
