with non-flashed GPUs, you can still easily boot OpenCore and view the entire boot process.</p> <p>Firstly, open the Terminal and run the following command:</p> <div class="language-sh extra-class"><pre class="language-sh"><code><span class="token function">sudo</span> nvram <span class="token string">"recovery-boot-mode=unused"</span> <span class="token operator">&&</span> <span class="token function">sudo</span> <span class="token function">reboot</span> recovery
|
|
</code></pre></div><p>This will make your machine reboot into the Recovery Environment. Alternatively, holding <code>Command</code> + <code>R</code> when your machine is starting up will also let you enter the Recovery.</p> <p>Secondly, open the Recovery Environment's Terminal (Menu bar > Utilities > Terminal).</p> <p>Now you'll want to get a list of drive identifiers. To do so, run the following command:</p> <div class="language-sh extra-class"><pre class="language-sh"><code>diskutil list
|
|
</code></pre></div><p>The command should produce a list of drives installed in your system:
|
|
<img src="/OpenCore-Legacy-Patcher/assets/img/Unflashed-Boot-1.ba0e58a4.png" alt=""></p> <p>Keep track of the drive with the OCLP install. You will need the drive identifer for later.</p> <p>Now you'll want to mount the EFI partition (where OCLP is installed, though it may differ if you've installed OCLP to a FAT-32 volume).</p> <p>Run the following command (Replace X with the drive number):</p> <div class="language-sh extra-class"><pre class="language-sh"><code>diskutil <span class="token function">mount</span> diskXs1
|
|
</code></pre></div><p><img src="/OpenCore-Legacy-Patcher/assets/img/Unflashed-Boot-2.5e873f39.png" alt="">
|
|
If everything is correct, the EFI partion should be mounted.</p> <p>Now you'll want to use the <code>bless</code> command to set the default boot device:</p> <div class="language-sh extra-class"><pre class="language-sh"><code>bless <span class="token parameter variable">--mount</span> /Volumes/EFI <span class="token parameter variable">--setBoot</span> <span class="token parameter variable">--file</span> /Volumes/EFI/System/Library/CoreServices/boot.efi
|
|
</code></pre></div><p>Once the command is run, it should produce no output.
|
|
<img src="/OpenCore-Legacy-Patcher/assets/img/Unflashed-Boot-3.79f71d03.png" alt=""></p> <p>If the command produces an output, ensure that you've typed it in correctly.</p> <p>Now you can reboot your machine. OCLP is now the default boot option!</p></details> <p>Now that you've loaded OpenCore, "select Install macOS":</p> <ul><li>This will be the OpenCore Picker</li></ul> <p><img src="/OpenCore-Legacy-Patcher/assets/img/oc-boot.3c2bdab5.png" alt=""></p> <p>You will soon reach the installer screen! If you enabled verbose mode when building OCLP, a lot of text will run across the screen. From there, it's just like any normal macOS install. For an example of how the boot process looks, see the following video:</p> <ul><li><a href="https://www.youtube.com/watch?v=AN3zsbQV_n4" target="_blank" rel="noopener noreferrer">OpenCore Legacy Patcher Boot Process<span><svg xmlns="http://www.w3.org/2000/svg" aria-hidden="true" focusable="false" x="0px" y="0px" viewBox="0 0 100 100" width="15" height="15" class="icon outbound"><path fill="currentColor" d="M18.8,85.1h56l0,0c2.2,0,4-1.8,4-4v-32h-8v28h-48v-48h28v-8h-32l0,0c-2.2,0-4,1.8-4,4v56C14.8,83.3,16.6,85.1,18.8,85.1z"></path> <polygon fill="currentColor" points="45.7,48.7 51.3,54.3 77.2,28.5 77.2,37.2 85.2,37.2 85.2,14.9 62.8,14.9 62.8,22.9 71.5,22.9"></polygon></svg> <span class="sr-only">(opens new window)</span></span></a></li></ul> <p>If your Mac is looping back into the beginning of the setup after the first reboot, turn it off, start it again and hold <code>Option</code>.
