# Adobe Air error message - macOSX Catalina

Some of our customers running Atollon using Adobe Air on Mac OS X Catalina have experienced the following issue:

**“Adobe AIR.framework” is damaged and can’t be opened.**

If you recently upgraded to Mac OS X Catalina, you may have this issue. You can resolve it by opening Terminal application (Open Finder and press Cmd+Shift+U > which opens Applications > Utilities and find Terminal).

Copy & paste the following commands:​​

```
cd /Library/Frameworks
sudo xattr -r -d com.apple.quarantine ./Adobe\ AIR.framework
```

You will need to enter your Mac OS administrator password.

Then try to install Adobe Air and Atollon Air client once again.
