(You need v12 or newer for Big Sur 11.3 or newer) Fetch the OSK authentication key

iso file extension, this is actually a hard disk image. Prepare an OpenCore imageĭownload the file from the newest release in my repository (that says it’s Big Sur compatible), double click it to unpack it, and upload it to Proxmox’s ISO store at /var/lib/vz/template/iso. This option is not available when building the installer on Linux. Simply ask it to build BigSur-full.img instead: cd scripts/bigsur If you’re building the installer on macOS, you can build a full installer instead of just a recovery, which will mean that macOS won’t have to download Big Sur files during installation, and so won’t require an Internet connection. 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 download the Big Sur installer from Apple’s software distribution servers and build a BigSur-recovery.img file for you. Now in the Terminal, from the root of OSX-KVM, run: cd scripts/bigsur If you’re building the ISO on Linux, you instead need to run this command (these are the package names for Ubuntu or similar distributions, they may need adjustment on other distributions): sudo apt install qemu-utils make If you will be building the installer ISO on macOS, open up the Terminal and run this command to install the commandline tools: xcode-select -install Modern AMD CPUs also support SSE 4.2 and will work with this guide.ĭownload my copy of the OSX-KVM repository using the download button, and unzip it:įirst we need to install some build requirements. Older CPUs will cause the finder to repeatedly crash after installation completes (with an Illegal Instruction exception in the graphics code). 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. You also need a real Mac available in order to fetch the OSK key. I’ll assume you already have Proxmox 6 installed. You can get the full sourcecode on my GitHub here. This tutorial for installing macOS Big Sur using OpenCore has been adapted for Proxmox from Kholia’s OSX-KVM project and Leoyzen’s OpenCore configuration for KVM. MacOS 12 Monterey is now available!
