I'm running
RefindPlus|OpenCore, and have successfully installed Ventura 13.5.1 with the assistance of OCLP. My post is only to help any other souls who might not be familiar with how to install macOS Ventura if they are using the
RefindPlus|OpenCore method on a cMP 4,1>5,1 Mac Pro.
The process I used is as follows:
MyBootMgr v094 - which includes
OpenCore v094.
First, with SIP
disabled
, I booted natively into macOS Mojave and ran
ConfigFactory which is part of the MyBootMgr suite of apps and utilities. In addition to creating the RefindPlus files it also creates ConfigFactory instances of OpenCore that allow one to run unsupported macOS's from Mojave through to Ventura. For example, in my case I have one OC instance for Monterey (EFI>OC_AAA), a VMM version for updating Monterey (EFI>OC_VMM), a version that supports legacy Catalina and BigSur instances (EFI>OC_LEG), and another one for Ventura (EFI>OC_EXT). When RefindPlus boots to its graphical pick list screen it presents those four instances of OC along with native boot options for Legacy Windows, Mojave etc (which boot natively - i.e. without OpenCore).
Note: I don't use the EFI files that ConfigFactory creates for Ventura - instead, I get OCLP to create the Ventura OC EFI files and I copy/paste these into the Ventura instance of OpenCore (EFI>OC_EXT).
Next, download and install the macOS Ventura 13.5.1 USB stick using OCLP v094. This is super easy due to the excellent instructions provided. Once the Ventura USB stick is ready, I mount the Ventura USB stick's EFI partition and copy the OpenCore folder to the Desktop so I make one change to the
config.plist
file - change
LauncherOption
to
=Disabled
(to prevent boot coups), save and then copy/paste the OCLP OpenCore EFI folder to my EFI>OC_EXT folder on my RefindPlus EFI partition.
Note: the OC instance for Ventura is now named
OC_EXT
when using MyBootMgr v094 (not OC_EXP with MyBootMgr v092).
So I then rebooted and selected my Ventura instance (OC_EXT) from the RefindPlus pick list, and then selected and booted to the Ventura 13.5.1 installer USB stick I created with OCLP. I installed Ventura to a spare SSD without incident - it restarted a few times (I selected the
macOS Installer disk icon for the first three reboots, and it finally then listed my Ventura SSD which I then finally booted to). After completing the macOS setup I was pleasantly surprised to see that the Ventura installer USB stick had already applied the OCLP post-install patches.
My cMP is running exceptionally smooth (I mean buttery slick), although I haven't installed my war chest of apps and files on my drive yet. Thank you devs 😍 and

Edited: With
MyBootMgr v094 the primary OC instance is now named
OC_AAA
, and the one generated for Ventura is named
OC_EXT
(previously
OC_EXP
). I changed the wording in my original post accordingly. I also corrected an error where I originally stated I was using MyBootMgr v068 - this was a typo.
Edited: With
MyBootMgr v120 (the latest version) there is a new layout for OC instances that support macOS Ventura and later. For "Venture and/or Sonoma", it creates an instance named
OC_X01
, and for "Sequoia and/or newer" an instance named
OC_X02
. After you've created the OpenCore instance in OCLP, copy the "contents" of the OC folder into
OC_X01
and
OC_X02
. Those two folders also have a helpful
IMPORTANT.text
file describing the intended purpose for
X01
and
X02
and with an important reminder to set
<LauncherOptions>
to
<Disabled>
in the respective
config.plist
files.
