# Use Debug Versions
## Switch to the Debug Version of OpenCore
* Launch OCAuxiliaryTools and open the relevant Config.plist.
* Modify the Config.plist debug settings as described here: [OpenCore Debugging | OpenCore Install Guide](https://dortania.github.io/OpenCore-Install-Guide/troubleshooting/debug.html)
* If you encounter problems during booting, you should utilize the *debug* version of OpenCore. As explained previously in the *Misc* section, make sure you have activated debugging and then *Select Menu -> Edit -> OpenCore DEBUG*
* Next, select *Menu -> Edit -> Upgrade OpenCore and Kexts* or click the *Upgrade OpenCore and Kexts* button.
* Then click: *Get the latest version of OpenCore*
* Then press the *Start Sync* button.
#### Back to release version
Once everything works, switch back to the *release* version by taking essentially the same steps:
* Select *Menu -> Edit -> OpenCore DEBUG* - This will uncheck *OpenCore DEBUG* in the Menu.
* Select *Menu -> Edit -> Upgrade OpenCore and Kexts* or click the *Upgrade OpenCore and Kexts* button.
* Press the *Start Sync* button.
* Also revert relevant debug settings in Config.plist:
* `AppleDebug = NO`
* `ApplePanic = NO`
* `Target = 0`
* In order to remove any remaining effects of the debug session, also `Reset NVRAM` (then check the correct BIOS boot order and set your default boot volume in OpenCore)
