WebAssembly (WASM) may be disabled for reasons that include compliance with security policies set by your organization, or non-support in older environments, for example.

TIP: The WebAssembly comparison table shows which WASM features are supported in your browser. 

You can check whether your browser supports WASM.

Follow these steps:

1. In your browser, open Developer Tools.
   • (MacOS) Chrome, Edge, Firefox: ⌘ + ⌥ + I
   • (Linux, Windows) Chrome, Edge, Firefox: Ctrl + Shift + I, or F12
   • (MacOS) Safari: Go to Settings > Advanced. Enable Show Develop menu in menu bar | Show features for web developers. Open Develop > Show JavaScript console.
2. In DevTools, click the Console tab.
3. In the console input line, type or paste typeof WebAssembly.
4. On your keyboard press ENTER.
5. Interpret the result:
   • If the console returns undefined, then WebAssembly is unsupported, or disabled.

   • If the console returns object, then WebAssembly is supported. 
     The DevTools console shows object when WASM is available in your browser.

     NOTE: If the console returns object and you are still unable to access Miro, you can review other possible issues and troubleshooting, or contact Miro Support.
