How to fix the issue
The issue is caused by kext mismatch after upgrade using "uninstall-install" strategy is performed. Old prl_netbridge kext is left on the system and loads before the build 3844 kext is loaded. In fact, the issue does not cause any negative impact on Parallels Desktop operation, it will work just fine. But the message itself is rather annoying as it appears each time a VM is started.
The issue appears only
- if you had upgraded to build 3844 using "uninstall old build - install new one" strategy, using Uninstaller application from build 3844 to delete older build
The issue will not appear in any of the following cases
- you upgraded using "install new build over old one" strategy
- you upgraded using automatic updater
- you deleted old build using old build's native uninstaller
If you have the issue on your Mac, the following solutions are possible
Solution (recommended):
- download the latest build with this issue fixed,
- use Uninstall application available on the just downloaded dmg to remove Parallels Desktop
- install Parallels Desktop.
