macOS 27 on your Intel PC.

Apple builds macOS 27 for Apple silicon only. Liberator moves an OpenCore PC with an NVIDIA card from macOS 15 or 26 to macOS 27 with one button. Your current macOS is kept.

Get Liberator How it works

This is a beta. It has been tested on one desktop PC: an Intel processor with an RTX 50-series card. It will have problems.

What it does

Liberator downloads macOS 27 from Apple, builds the Intel startup files, puts macOS 27 on its own new volumes beside the macOS you use now, and installs the NullMoth NVIDIA driver there.

It also adds the layer that runs Apple's arm64-only programs on an Intel processor. Nothing on your current macOS is changed.

Before you start

macOS 15 or macOS 26 running through OpenCore, with the NullMoth NVIDIA driver working.
About 102 GB free on the macOS disk. About 27 GB of that is downloads, most of it macOS 27 from Apple.
A wired network connection. Wi-Fi and Bluetooth do not work on macOS 27 yet.
About 30 minutes, plus the download.
A backup of anything you cannot lose, and the know-how to get back to your working macOS.

Step by step

Unzip the download and open Liberator on macOS 15 or 26.
Leave Set up as a new Mac unticked to bring your account over, or tick it to start at Apple's setup.
Press Prepare for Golden Gate and confirm once. Nothing is changed before you confirm.
Leave the PC on and connected while the bar runs.
When it says it is done, restart. macOS 27 is the default in the boot picker.

If it stops part-way, press the button again. Steps that finished are not repeated and the downloads are kept.

The first start

Start text appears and pauses at PCI configuration for up to two minutes. That is normal: wait. Then sign in with your usual name and password.

Going back

Choose your macOS 15 or 26 disk in the OpenCore boot picker and open Liberator there.

Cancel Golden Gate puts your old startup files back.
Remove macOS 27 puts them back and erases the macOS 27 volumes Liberator made. It asks first.
Clear downloads frees about 27 GB.

Known problems in Beta 1

No Wi-Fi and no Bluetooth.
Spotlight search does not work.
Books, Journal, Maps, Reminders and Voice Memos do not work yet.
The login window can say the System keychain cannot be found. Press Cancel.
The Dock and other glass surfaces can look flat and dark.
System Integrity Protection is lowered and Apple's code-signing enforcement is off on macOS 27. Treat it as a test system.

If something goes wrong

Problems can only be fixed from your logs. Start macOS 15 or 26 from the boot picker and press Send a report in Liberator: it reads the macOS 27 logs from there. Then post the report ID in the Discord or on r/1401.
