Linux users assume everything is fine and that enough skeptical eyes are scrutinizing every little contribution. Linux is a free and open-source OS developed by a loosely organized collective of individual contributors and organizations. Things get a bit more complicated if you’ve bought a computer and you run Linux on it. (It may be deeply uncomfortable to pause and give it some thought.) Customers rarely think about the required trust levels. Bought a Dell running Windows? Then you trust Dell and Microsoft. You implicitly trust your hardware vendor’s firmware. It can do anything it wants on your computer. The first software that runs on your computer after it’s been powered on runs in absolute unrestricted security (“God”) mode. To me, the Apple experience doesn’t involve installing third-party UEFI and bootloaders. It’s deeply weird to me that I have to turn my MacBook into a Hackintosh to continue running Apple’s latest software. It can run on legacy Mac products and computers from other manufacturers. OpenCore works by replicating the behaviors MacOS expects from UEFI and iBoot on a supported Mac on an unsupported system. OpenCore is a free and open-source replacement for Apple UEFI and iBoot (Apple’s bootloader) software. Among other things it’s responsible for booting the OS, and it also provides services to the OS afterwards. The Unified Extensible Firmware Interface ( UEFI) is low-level software that sits in between the hardware’s firmware and the operating system ( OS) software. The current star in the Hackintosh community is the OpenCore UEFI emulator and bootloader project. That’s more of an encouragement than anything to dedicated folks who want to do exactly that. Apple includes all sorts of software-based copy protections to make sure its software only runs on its hardware products. Sure, it has needed some maintenance and a battery swap, but it’s otherwise in good condition.Ī Hackintosh usually refers to a computer from another manufacturer running Apple software. However, the hardware is still perfectly capable of running Monterey. My MacBook Pro (a 2013 model) won’t receive any more love (updates) from Apple as the company left it behind with the release of MacOS version 12 “Monterey”. However, can you trust its community-developed software to the same degree as you blindly trust Apple? The Hackintosh scene, a community dedicated to running MacOS on unsupported hardware, might help extend the life of your Mac. So yes, this is a way forward for a legacy machine.Apple periodically drops support for its older hardware, and customers get left with an increasingly insecure and outdated system. Youtubing and other media seems to go smoothly. I believe they are running in a pseudo software mode. You can tell however that the 3D graphics aren’t as smooth as you would otherwise experience them. I’ve installed Office, Unity (latest LTS), Blender, Visual Studio, Teams,… and all seem to be working. I can only connect my USB-headset after boot, otherwise the internal speakers of the iMac aren’t recognized.I was able to resolve this by rolling back to version 2108 for mac. The most recent version of Citrix Workspace just displays a white window.The sliders for volume, brightness,… aren’t visible.Selecting the network from the list did nothing I had to manually enter the wifi SSID & code in the wireless settings menu.I had to set the font to dark with this terminal command:ĭefaults write -g ASB_DarkMenuBar -bool true The menu bar on top was unreadable with a light background.To resolve this I had to use ResXtreme to change colours from billions to millions. There was flickering of the screen after installing the GPU-fix.So with nothing to lose, I attempted this solution on my old iMac.Īnd it worked! But… I ran into the following issues: The project offers a ‘beta’ solution to support the card somewhat. A solution would be to replace this GPU with a metal-capable GPU, but I do not want to invest €’s in a decade old piece of hardware. However there is one big caveat: The GPU (Radeon HD 6750M) is a non-metal supporting device. With this application it is easy to install macOS Monterey on the iMac 12.1. One of these projects resulted in OpenCore Legacy Patcher. There is however a community online which does their best to run more recent versions of macOS on unsupported machines. Macos High Sierra is version 10.13, the OS has been out of this 3 version cycle since Big Sur, the previous version of macOS. Most manufacturers support only the last 3 versions of macOS for their applications. The main reason being no recent application updates, for applications such as: The last OS officially supported by the iMac 2011 (iMac 12,1 – Mid2011) is macOS High Sierra.
