## Booting without USB drive

Once you've installed macOS through OpenCore, you can boot up and go through the regular install process. To boot without the USB drive plugged in is quite simple:

* Download OpenCore Legacy Patcher
* Change Patcher settings as you'd like
* Build OpenCore again
* Install OpenCore to internal drive
* Reboot holding Option, and select the internal EFI

And voila! No more USB drive required

## Booting seamlessly without Verbose or OpenCore Picker

To do this, run the OpenCore Patcher and head to Patcher Settings:

| GUI Settings | TUI Settings
| :--- | :--- |
|![](../images/OCLP-GUI-Settings-ShowPicker.png) | ![](../images/OCLP-TUI-Settings.png) |

Here you can change different patcher settings, however the main interest is:

* Show Boot Picker (GUI)
* Set ShowPicker Mode (TUI)

Once you've toggled them both off, build your OpenCore EFI once again and install to your desired drive. Now to show the OpenCore selector, you can simply hold down the "ESC" key while clicking on EFI boot, then you can release the "ESC" key when you see the cursor arrow at the top left.

## Enabling SIP

For many users, SIP will be enabled by default on build. For Intel HD 4000 users, you may have noticed that SIP is partially disabled. This is to ensure full compatibility with macOS Monterey and allow seamless booting between it and older OSes. However for users who do not plan to boot Monterey, you can re-enable under Patcher Settings.

Note: Machines with non-Metal GPUs cannot enable SIP in Big Sur either due to patched root volume

| SIP Enabled | SIP Lowered (Root Patching) | SIP Disabled |

::: warning 

If you're unsure whether you should enable SIP, leave as-is. Systems where you have already ran the Post Install Root Patching cannot enable SIP without potentially breaking the current install.

## Applying Post Install Volume Patches

Users with OCLP v0.4.4 or higher will be prompted to install these patches after installation or whenever patches are not detected on the system. We recommend rebuilding OpenCore with the latest version of OCLP to take advantage of these new features.

### Running Post Install patches manually

If you're using OCLP v0.4.3 or earlier, or need to run the patcher manually, you can do so with the app. There is no harm in trying to run the Patcher, as without compatible hardware nothing will be done. You can see below on whether your hardware needs root volume patching.

::: warning

With OpenCore Legacy Patcher versions prior to v0.4.4, Root Patching requires a network connection by default to grab associated resources. If your system is having difficulties with wifi or ethernet, you can grab the newest release :
