Read this as one machine’s walkthrough.

The Windows preparation was re-recorded with 1401 2.3.5. The macOS installation and driver sequence come from an earlier session. The final status does not record an installed-driver package version. This guide keeps those sessions distinct.

Before you start

This process boots macOS through OpenCore. It involves creating an installer USB, changing firmware settings, selecting storage, and installing a third-party graphics driver. A working Windows installation is the starting point shown here.

Use these details to understand the example, rather than as a compatibility guarantee for a similar-looking PC. Your motherboard, network hardware, graphics card, and chosen macOS version all need checking.

• Back up important files and keep a way to boot Windows.
• Prepare a USB device whose contents you can erase.
• Identify the separate disk or partition intended for macOS before starting.
• Keep internet access available and save the BIOS instructions generated for your hardware.
• Read the project’s card-support notes before assuming your GPU is covered.

Two different erase operations are involved.

The USB writer erases the selected USB device. Later, Disk Utility erases the selected macOS destination. Verify the target at both stages; the correct choice in one screen does not make the other safe automatically.

Stage 01 · Windows

Download 1401 and check your hardware

Watch from 1:35 ↗

1. Open the linked 1401 2.3.5 Windows release to match the preparation footage. Download its Windows package and extract the complete folder.
2. Launch the 1401 assistant. Keep its supporting files together rather than moving only the executable.
3. Review the macOS selection shown in the assistant. This recorded preparation selects macOS 26 Tahoe.
4. Run Check this PC and inspect the detected hardware. Confirm that the board, CPU, and graphics information match the machine you are preparing.

2:35 in the video · Review the scan results before building the configuration. Select a screenshot to revisit that moment in the video.

Continue to Build the Mac setup and let the build complete. This stage prepares the OpenCore configuration for the detected hardware. If the scan or build reports a problem, resolve that before writing the USB.

3:05 · Building the setup. Progress shown in an edited video is not a promise of the same build time on another PC.

Checkpoint

The hardware scan has completed and the assistant can advance from the build to the BIOS instructions.

Stage 02 · Installer media

Save the BIOS plan and create the USB

Watch USB creation from 3:37 ↗

Read Your BIOS steps before restarting. The assistant gives instructions for the selected hardware, including preparation around Windows device encryption. Keep your recovery information available before changing firmware settings.

1. Connect the USB device you intend to use.
2. Open Create the macOS stick.
3. Check the selected device’s name, capacity, and drive letter. Do not copy the recording’s device selection onto a different PC.
4. Use Erase and create only after confirming the selected device can be erased. Wait for the assistant’s completion screen.

3:55 · Check the USB selector before writing. The drive shown is the creator’s device, not a universal selection.

Checkpoint

The assistant reports that the macOS stick is ready. Keep it connected for the next stage.

Stage 03 · Firmware & boot

Apply the BIOS instructions and boot OpenCore

Watch from 4:24 ↗

Restart into your motherboard’s firmware settings and follow the plan you saved. The recording uses a GIGABYTE AORUS interface. Another motherboard may put the same controls in different places.

The recorded Boot page shows Fast Boot and CSM Support disabled; the narration also identifies Above 4G Decoding as enabled on this machine. Treat these as this board’s recorded settings, not a complete BIOS prescription. Save the required changes, select the installer USB’s UEFI boot entry, and continue through OpenCore to macOS Recovery.

4:35 · The actual AORUS Boot page. Use the generated instructions for your own hardware.

Checkpoint

You reach the macOS Recovery screen with Disk Utility and the macOS installer available.

Stage 04 · macOS installation

Prepare the correct destination and install Tahoe

Watch from 5:20 ↗

1. Open Disk Utility from Recovery, then select View → Show All Devices.
2. Identify the intended macOS destination using its name, capacity, and position among the other volumes. The example target is an existing target named Hackintosh, about 130 GB. Other volumes share the physical drive; the recording does not erase that whole drive.
3. Check the erase dialog carefully and choose APFS for the intended macOS destination. Confirm only once the selected target is correct.
4. After the erase completes, close Disk Utility. Open Reinstall macOS Tahoe and select the prepared destination.
5. Let the installation and its restarts complete, using the prepared OpenCore USB as needed.

5:50 · The target check before changing the format. This frame still shows the old NTFS selection; the next action is to choose APFS. Do not erase the Windows or data volumes beside it.

6:20 · Tahoe installation on the selected target. The edited wait is shorter than the real installation.

The setup screen that stopped progressing

At about 7:18, the recording reaches an update-related setup screen that stops progressing. The narration says the creator waited roughly another 46 minutes before restarting and later reaching the installed desktop. That is the recovery shown for this session; it is not a timed restart instruction for other installations.

7:20 · The stalled setup screen in this recording, before the restart and later desktop.

Checkpoint

The installed macOS desktop opens. Graphics-driver setup is a separate stage that follows.

Stage 05 · NVIDIA driver

Review the Mac companion’s plan before installing

Watch from 7:48 ↗

In macOS, the video opens the NullMoth folder on the USB and launches the Mac companion. This is the older installation session, so the package visible here should not be relabelled as a verified 2.3.5 driver installation.

1. Keep the OpenCore USB connected and open the Mac companion from the recorded workflow.
2. Check the detected system, GPU, and OpenCore boot source.
3. Read the proposed driver and OpenCore changes before starting the installation. Use a supported OpenCore source the tool can identify.
4. Follow the installation prompts. When macOS requests extension approval, open System Settings → Privacy & Security and review the request.
5. Complete the required restart, continuing to boot through the intended OpenCore setup.

8:10 · Read the plan before applying the driver and boot-configuration changes.

9:05 · The Privacy & Security stage shown after the extension prompt. Follow the prompts for your actual package.

For changes in newer packages, use the linked driver documentation. Avoid combining old manual commands with a newer companion’s automated changes without understanding the difference.

Stage 06 · Verification

Check the running result—and what it establishes

Watch from 9:18 ↗

After the restart, open the companion again and inspect its status. The recording shows loaded NullMoth components and a visible NVIDIA Metal device, followed by basic desktop use and a short browser video-playback example.

9:45 · The actual running-status screen. It does not provide an installed-driver package version for this session.

• Confirm the installed system boots again through the intended OpenCore USB.
• Check the companion’s device and component status after restarting.
• Try the desktop and the specific apps you plan to use, and record any problems separately.
• Keep the boot USB and recovery route available before making further changes.

This recording does not include a controlled graphics benchmark, comprehensive application tests, sleep/wake validation, or a multiple-display test. It also does not demonstrate transferring OpenCore to an internal EFI partition or verified booting without the USB.

If your result differs

Where you are stuck	What to check next
Hardware scan or build fails	Read the assistant’s result and the project’s current instructions before writing another USB. Keep the error details.
The USB does not reach Recovery	Recheck the USB build, its UEFI boot entry, and the BIOS plan for your machine. The video’s AORUS settings are only one example.
Unsure which volume to erase	Stop at the target-selection stage. Identify the disk and partition using your own layout; a familiar name alone is not enough.
Setup appears stalled	Compare the exact screen with the recording at 7:18. Its successful restart is a session-specific observation, not a universal fix.
No running driver status after restart	Check extension approval, the OpenCore boot source, and the driver’s current troubleshooting notes.
Need to recover from a driver problem	The recording shows a removal/recovery route near 10:21. Verify the instructions for your installed package before using it.

The useful end point is a repeatable boot with the expected device status and working checks for your own use. Keep the project documentation close as you test beyond what this video demonstrates.
