If your Mac lacks native boot screen support OpenCore will start and is selected for booting automatically. ➋ Use the arrow keys to select "EFI Boot", then holding Control, press Enter. ➊ Reboot and hold Option to enter Startup Manager. If your Mac has native boot-screen support □ Congratulations! You now have a basic OpenCore setup and are ready for the first boot. all folders in the folder "Acidanthera", except for the folder "GoldenGate".all files in the folder "Drivers", except for the files "OpenCanopy.efi" and "OpenRuntime.efi".all files in the folders "Audio" and "Tools".To keep things nice and tidy, the following files and folders can be deleted: ➍ Verify that your ESP contains the following files and folders: Copy the folder "Resources" to the folder "OC", overwriting the existing folder of the same name. It is the most important part of your setup. ➋ In the folder "EFI" (now on your ESP), you will see a folder "OC". In this case, you can safely delete the existing folder before. It is possible that your ESP already contains a folder "EFI" (Macs use EFI partitions as a staging area for firmware updates). In the folder "X64", you will see a folder "EFI".

It took over a year and the release of OCLP for the larger unsupported-Mac community to finally embrace OpenCore. Even Acidanthera took notice and stepped in to solve the most enduring problem with the classic Mac Pro: the lack of preboot graphics with standard graphics cards. This solution received a lot of attention from the Mac Pro community and led to finally activating AMD hardware acceleration. In late 2019, the first OpenCore solution for installing, running and updating macOS on Apple hardware was presented here in this guide. Shortly after this release, Catalina Loader, a partial OpenCore solution for legacy Apple hardware, was proposed by Somewhat of a curiosity at this stage, the solution was only for tricking the macOS installer, not for actually running macOS. After a complete rewrite, they released the first version of OpenCore in mid 2019. In the mid-to-late 2010s, Acidanthera, a group of developers led by and mhaeuser, revisited the project. Although Quo enjoyed a successful 2013 Kickstarter campaign, the company no longer exists. ![]() ![]() The group became well-known for the Ozmosis project, a firmware-based bootloader developed for Quo Computer's Any-Operating-System motherboard. OpenCore can be traced back to a group of anonymous developers known as The Hermit Crabs Labs. OCLP (comprehensive automatic solution for setting up OpenCore based on your hardware).OC Plistlib Generator (programatic solution compatible with this guide for easily maintaining and updating your OpenCore setup).MyBootMgr (RefindPlus chain-loading solution with helper apps).Martin's Package (popular one-size-fits-all solution).Since this guide first appeared, several approaches have been proposed to facilitate the use of OpenCore on the 2009–2012 Mac Pro: Supported modules (such as BCM94360CD and BCM943602CDP) Supported GPU (such as RX 580, Radeon VII, and 5700 XT) Westmere (E56xx, L56xx, and X56xx) or Gulftown (W36xx) ![]()
