Please describe your issue in as much detail as possible:

Since the Ringmaster update, Dota 2 will no longer launch on my computer, running macOS 10.13.6, at all. It worked fine yesterday, before the update. According to the the crashlog, it appears that the dota2 binary has been built for macOS 10.15 as the minimum. Crashlog:

Was this a build mistake? I could not find any release notes or announcements that indicated that the minimum OS requirements had been raised. The Store page still lists macOS 10.13.6 as the official minimum OS required:

Steps for reproducing this issue:

1. Have latest dota2 update installed
2. Be running macOS 10.13 or 10.14
3. Game crashes immediately upon trying to launch.

Running the Dota 2 binary directly, instead of through Steam, will fix the problem, and you won't experience crashes.

That had no effect. Launching the binary directly led to the same failure to launch, with the crash report containing the same infomation as above.

Same issue on mac os 13.2, can't launch dota via steam/binary

Same here on 15.0 Beta (24A5327a)...Tried even running the binary but no difference

I found this fix from Steam forums (I'm on M3 Pro Sequoia)

Run this command from terminal and it should work fine.
open -n ~/Library/Application\ Support/Steam/steamapps/common/dota\ 2\ beta/game/bin/osx64/dota2.app --args -map dota -novid -vulkan -nojoy -novr -high -prewarm

No, none of that works or has any effect. Please stop posting in this bug if you have Apple Silicon. This bug is only for running on macOS 10.13 and 10.14. This has nothing to do with Apple Silicon or Error 24.

Thank you! This worked for me on MacOs Ventura 13.70

As a suggestion after the game loads change the resolution to windowed and something lower than your current desktop.
