# Why is TSB not launching in Mac?

If Talview Secure Browser (TSB) doesn’t launch on your Mac, macOS security may be blocking it, preventing you from proceeding with the test. This is common when installing apps from outside the App Store.

## ✅ Common Causes and Fixes

| TSB wasn’t installed correctly              | Delete the app, then [download the latest version](https://pages.talview.com/securebrowser/) and reinstall it. |
| You opened the file directly from Downloads | Move TSB to your **Applications** folder and launch it from there.                                             |
| Mac doesn't show any warning at all         | Open `System Settings → Security → Allow Apps from Identified Developers.`                                     |
| Background restrictions or slow startup     | Restart your Mac, close all other apps, then try launching TSB again.                                          |
