Expected: Dota launches with -vulkan flag either when set in launch options from Steam or passed in from command line, using Vulkan like I've told it to Actual: Dota tries starting up, then this error appears:

Then Dota shuts itself down.

This bug happens to me every few months and seems disconnected from the timing of OS, Dota, or Steam updates. It's most similar to #1904 which was eventually resolved by the bug reporter after restarting + redownloading dota multiple times – usually this is also what works for me, but not this time. I was able to play fine yesterday but today I tried opening dota from Steam and Steam froze my entire computer, so I restarted the computer – and then this problem appeared again.

From command line:

$ ./dota.sh -vulkan -vconsole -con_logfile

Your graphics card must support at least OpenGL v3.1.

I've also tried the -gl launch option but it doesn't seem to make a difference. I've also ensured that Dota isn't being blocked by antivirus software. Please good folks I just want to play one (1) game of Dota as a treat.

Steps for reproducing this issue:

1. Open dota on a mac
2. ???
3. Do not profit.

this happens randomly, sometimes u can launch the game a few hours later without even rebooting the machine

it persists for a year or more but apparently nobody will fix it
