Also, keep in mind the capabilities of the power supply. Please check the TDP rating of your new CPU. Keep in mind, the cooling solution included in the machine is rated to 65W in case of the 3020 MT and SFF, and 35W in case of the 3020M.
Ideally, I would install an i5-4590S, since we're going to fake our machine like an iMac 15,1, and this machine was shipped with this exact CPU. Consider upgrading to a CPU, that has Intel HD4600 graphics instead, LGA1150 Haswell CPUs are pretty cheap on the used market. No Mac computer was shipped with this iGPU, so it is not surprising that it has issues. The problem with the i3-4150 CPU is that it has Intel HD4400 graphics, which will work, but it will have some small issues, which I explain in this guide later. This may vary between machines, so check your configuration. CPUīy default, my machine came with an Intel i3-4150 CPU, which is fine, but not ideal for a Hackintosh machine. If you're not interested in hardware upgrades, you can skip this section, but I strongly recommend using a CPU with Intel HD4600 at least. In this section, we'll be going through all the possible upgrades you might want to consider for the machine.
You should consider some hardware upgrades to this machine, to archive the best results possible. Displayport cable, since the VGA port will not work.
I have no fixes for this issue at the moment, if the System Preferences update fails, you have to update via an install USB.Ībout INTEL HD4400 with Big Sur: With the latest kexts, Big Sur is now usable with Intel HD4400. NOTICE: Some users (including me) experienced a problem when tried to update Catalina to Big Sur from System Preferences, as after the install, the machine booted back to Catalina like nothing was changed. If you want to update from Catalina, go to the System Preferences, check for updates and just install it.
This EFI may work with Catalina too, although I don't test it anymore. I started this guide in the Catalina days, now I only cover Big Sur, as it is pretty stable at this point. Since I'm an active Hackintosh user on this machine, I will update the EFI periodically here as anything new is available.Ĭurrently, this EFI is based on OpenCore 0.7.4 and supports macOS Big Sur (Monterey support coming soon!). About the version of OpenCore, and the kext files In this guide, I going to explain to you the installation process, as well as some considerations in the hardware configuration, to make you a perfect Mac computer, cheaply. As it turned out, it is a fully capable Hackintosh candidate, with all functionalities working. When I got my hands on mine, I had no idea what to do with it, but based on a suggestion of my roommate, I've decided to turn it into a Hackintosh. The Dell Optiplex 3020 is a common and cheap business computer, based on the 4th gen Intel Core CPU family, and the Intel Series 8 chipset. Use this guide at your own responsibility. If you find any issues, feel free to open a ticket, or send me a message. I'm not responsible for any negative consequences if you follow this guide, and something goes wrong. This guide covers the following macOS versions:Īs I am a human being, like you, I make mistakes.
This repository contains a guide on how to install macOS on the Dell Optiplex 3020, with the necessary files, using OpenCore bootloader.
