Hearthstone crashes crashes on Mac when Razer Synapse is running

Hello,

I recently discovered an issue on my M2 Mac Studio where I was unable to open Hearthstone.

Anytime I opened it, it would crash.

After a lot of head scratching, digging into config files, and finally just wiping the SSD and installing a fresh version of Tahoe…I still had the problem!

My post on the Hearthstone forums sat for days before there was any notice/traction and another person finally responded to say that Hearthstone worked after quitting the Synapse App.

I tested this myself and sure enough, after quitting Synapse, Hearthstone ran without issue.

Has anyone else run into this issue?

If so, are there any solutions for it or are we just stuck with, “Close Synapse in order to play Hearthstone” until a fix is released?

Had the same exact issue.

The game would not open no matter what I did, then I saw your post and tried it and it worked.

Hello!  After creating this post I ended up submitting a ticket to razer support.

They were very helpful and are looking into this issue.

The issue appears to be related to the “Razer Virtual HID Driver Extension” and the workaround is to disable it.

So, you can leave Synapse running when playing HS, but that extension will just be disabled.

The only drawback to this is that you will then get an annoying “System Permission Needed” box permanently showing on every panel in Synapse.

The extension is for game controllers, so if you have a game controller and need that extension then I guess you’ll have to turn off Synapse completely so that HS will run.

If you want to disable the extension, the navigation path is below...

Navigation:
System Settings → General → Login & Extensions → Razer Synapse Extensions → Toggle “Razer Virtual HID Driver Extension” to Off.
