Hey there! We’re currently not aware of any issues at the moment, but we’ll keep checking and tracking for issues with Mojave. There’s a few things that we want to check for since this has helped with voice chat issues in the past.
- Could you make sure Heroes of the Storm has accessibility permissions? Go to System Preferences > Security & Privacy > Privacy > Accessibility. If Heroes of the Storm is listed, make sure it is checked.
- If the game is not listed here, you can proc the permissions prompt by checking Disable OS Keyboard Shortcuts option under Mouse & Keyboard in Heroes of the Storm.
There is one suggestion that has helped others in the past, but this is not supported by Blizzard. Please only try this if you are comfortable with terminal commands and under your own discretion.
