- Quick Slack completely
- In a terminal, run the following commands
export SLACK_DEVELOPER_MENU=true
open /Applications/Slack.app
- This will open a new Slack instance but you're now able to access the developer tools.
- Use the
cmd + opt + I
keyboard combination to open dev tools - Switch to the console tab and run the following command
localStorage.localConfig_v2 = localStorage.localConfig_v2.replace(/\"is_unified_user_client_enabled\":true/g, '\"is_unified_user_client_enabled\": false')
- Viola, old Slack UI
