macOS Ventura on unsupported Mac

In former posts, Big Sur and Monterey, I went through how to update an old MacBook Air 4.2, (mid 2011, SSD, 4 Gb memory) which has a Non-Metal GPU.

In this post I will update a MacBook Air 6.2 with SSD, Mid 2013,
 to Ventura with the same patcher but the latest version 6.2 !! 

This is despite that max OS for this Mac is Big Sur

Awesome !!!

Supported models are found here.

Patcher manual
The manual for the OpenCore Legacy Patcher(OLCP) is nice and there are also a recent video how to use the OLCP version 6.1 using the GUI.

Downloading OLCP

Download the ”OpenCore-Patcher-GUI.app.zip” file at, unzip it and execute.


Create bootable USB

You can create installers, for the most recent OS, via OLCP.

Another way is checking this post which will also give older variants to choose from.


Building/installing the patcher

After that follow these instructions, and/or the above video, on how to install and use the OLCP.


Good luck !

Remarks
  • If your Mac have a SSD it will really improve performance versus an old hard disk !
  • If you are coming from an OS, several versions back, I really think that you should erase/format the MAC HD/SSD before installation !! This does it more simple for the installer and you will delete accumulated garbage. But don't forget the backup or trust in iCloud.
    • With an old non SSD HD use "Mac OS Extended(journaled)" 
    • With en SSD use "APFS"
  • If possible download the OLCP app and build the installer on the same Mac you aim to upgrade. (Not valid if you erase the disk before install.)
  • The Mac rebooted several times during install
  • Don't eject/remove the USB until at the very end.
  • When finished "Settings => Build => Show OpenCore Boot Picker" uncheck.          
  • If on a Mac with non metall video card these changes could be nice. "Settings => Root Patching". Dark Meny bar & Enable Beta Blur
