# Upgrade OpenCore
## Upgrade OpenCore and Kexts
Currently, the easiest method to keep your OpenCore files, drivers, config and kexts up to date is to use OCAuxiliaryTools.
### Updating the Config.plist
OCAuxiliaryTools actually merges any changes made to the structure of the Config.plist and feature-set, thereby updating it to the latest version, without losing settings. It integrates the tasks which had to be handled manually by multiple separate tools in the past such as [*OCConfigCompare*](https://github.com/corpnewt/OCConfigCompare) */* [*Meld*](https://yousseb.github.io/meld/), [*KextUpdater*](https://github.com/MacThings/kextupdater), [*ProperTree*](https://github.com/corpnewt/ProperTree) and [*OCValidate*](https://github.com/acidanthera/OpenCorePkg/tree/master/Utilities/ocvalidate).
* Mount your EFI partition: *Menu -> Edit -> Mount ESP Partition,* or click the Mount ESP button. Only mount one EFI partition at a time!
* Then click: *Mount and open Config.plist*
It is recommended to perform the upgrade first on a USB-stick and then transfer the EFI, after you are sure that the upgrade was successful. In any case backup your EFI first before making any changes.
* Select *Menu -> Edit -> Backup EFI to Desktop* or click the *Backup EFI to Desktop* button.
* Select *Menu -> Edit -> Upgrade OpenCore and Kexts* or click the *Upgrade OpenCore and Kexts* button. - If your Config.plist is outdated, you should see some OC Validate warnings indicated by a red exclamation mark on the OC Validate button.
* Clicking on the red button will show the errors.
* Close the *OC Validate* dialog. Click the *Save* button, which will update the Config.plist and get rid of all or most of the shown errors.
* Correct any remaining errors as indicated by OC Validate. The OC Validate button will change from red into a checkmark. This should be sufficient for updating your Config.plist.
* Note: Any additional errors are most likely configuration errors which you need to fix on your own. Also refer to [Updating OpenCore and macOS | OpenCore Post-Install](https://dortania.github.io/OpenCore-Post-Install/universal/update.html) in the Dortania guide, which provides more details.
### Upgrading Kexts
Occasionally you may need to remove a kext (or driver) which is not needed any more for the newest version of OpenCore or which has been replaced with another. Deleting kexts in the *Kernel -> Add* section will remove them from the Config.plist, but not from the disk. Since *OCAuxiliaryTools* automatically syncs changes on disk with the kext list in Config.plist, it is easier to just delete them from the disk. From the *Kernel - Add* section select *Menu -> File -> Browse* to show your current kexts in the Finder. Then delete any outdated kext.
* Next, select *Menu -> Edit -> Upgrade OpenCore and Kexts* or click the *Upgrade OpenCore and Kexts* button.
* In this dialog window we see Kexts on the left and OpenCore files on the right with indicators which files will need to be updated: Green = up-to-date, Red = outdated, Gray = link to repo is missing. You can add a repo link for kexts in *Settings -> Kext Update URL -> \[+]*.
three kexts need to be updated in this example
* Click on the *Settings* Button*,* referring to: *`The way to get the download link for Kext upgrade`* and ensure that `Accessing the GitHub API` is checked, as shown below.
* We will start with the kexts. Therefore, click *Select All* or individually mark the checkboxes for kexts you want to update (otherwise they will be ignored).
* Click on *Check for Kexts Updates*. This will download the latest available kexts.
* Click on *Update Kexts*, which will update the kexts in your EFI folder.
kexts fully updated to the current stable versions
* If you want to use the development versions of the kexts instead, select the DEV checkbox first.
### Upgrading OpenCore, Drivers and Resources
* On the right side of the above shown dialog window, the relevant files to be upgraded should already be selected automatically in the OpenCore file table
* On the same side there is a drop down menu to *Choose OpenCore Version:* select *"Latest Version"*, then click *"Get OpenCore".* It will automatically update to the latest available release version of OpenCore, and it will intelligently adapt to the Config.plist parameters of that version.
* Then press the *Start Sync* button.
* If you check back in the *Sync* window, all OpenCore files should now be marked green.
### NOTES
* Much of the *Upgrade OpenCore and Kexts* portion of this guide is based on [Updating OpenCore and Kexts with OCAT](https://github.com/5T33Z0/OC-Little-Translated/blob/main/D_Updating_OpenCore/README.md) by 5T33Z0. *Some possible issues are also discussed there.*
