::: details Note for Mac Pros/Xserves/iMacs with unflashed GPUs
(Adapted from the [OpenCore on the Mac Pro guide](https://forums.macrumors.com/threads/opencore-on-the-mac-pro.2207814/))
For Mac Pro, Xserve and, iMac users with non-flashed GPUs, you can still easily boot OpenCore and view the entire boot process.
Firstly, open the Terminal and run the following command:
```sh
sudo nvram "recovery-boot-mode=unused" && sudo reboot recovery
```
This will make your machine reboot into the Recovery Environment. Alternatively, holding Command + R when your machine is starting up will also let you enter the Recovery.
Secondly, open the Recovery Environment's Terminal (Menu bar > Utilities > Terminal).
Now you'll want to get a list of drive identifiers. To do so, run the following command:
```sh
diskutil list
```
The command should produce a list of drives installed in your system:

Keep track of the drive with the OCLP install. You will need the drive identifer for later.
Now you'll want to mount the EFI partition (where OCLP is installed, though may differ if you've installed OCLP to a FAT-32 volume).
Run the following command (Replace X with the drive number):
```sh
diskutil mount diskXs1
```

If everything is correct, the EFI partion should be mounted.
Now you'll want to use the bless command to set the default boot device:
```sh
bless --mount /Volumes/EFI --setBoot --file /Volumes/EFI/System/Library/CoreServices/boot.efi
```
Once the command is run, it should produce no output.

If the command produces an output, ensure that you've typed it in correctly.
Now you can reboot your machine. OCLP is now the default boot option!
