Prepare an OpenCore imageĭownload the file from the newest release in my repository (you need v13 or newer), double click it to unpack it, and upload it to Proxmox’s ISO store at /var/lib/vz/template/iso. Although we’re putting it in the ISO directory so that we can use it with Proxmox’s ISO picker later, this a raw disk image rather than a true ISO. Upload this file to your Proxmox’s ISO store directory (typically /var/lib/vz/template/iso). This will build a Monterey-full.img file in the scripts/monterey directory for you. Now from the root of OSX-KVM, run: cd scripts/monterey Open up the Terminal and run this command to install the commandline tools: xcode-select -install Just exit out of the install wizard when it says “to set up the installation of macOS 12 Beta, click Continue” and you should be left with “Install macOS 12 Beta” in your Applications folder.ĭownload my copy of the OSX-KVM repository using the download button, and unzip it: Since Monterey is still in closed Developer Beta, you need to opt-in to the Apple beta program and grab Monterey from System Update. Modern AMD CPUs also support SSE 4.2 and will work with this guide. Older CPUs will cause Illegal Instruction crashes when apps/extensions attempt to use these missing instructions. Your Proxmox host computer’s CPU must support SSE 4.2, so for Intel your CPU must be at least as new as Nehalem, which was the first CPU generation to bear the “Core” i5/i7 branding. Since Monterey is still in closed Developer Beta, you need to be an Apple Developer and have access to a Mac (or Mac VM) to download it. You can get the full sourcecode of my OpenCore release on my GitHub here. This tutorial for installing macOS Monterey Developer Beta has been adapted for Proxmox from Kholia’s OSX-KVM project and Leoyzen’s OpenCore configuration for KVM.

With the public release of Monterey, this guide is now obsolete, please use my new installation guide instead
