OpenCore's version number does not represent the quality of the project. # Common Myths # Is OpenCore unstable as it's a beta?
Does not support macOS-only ACPI injection and patching. Does not support changing settings within OpenCore's menu. Does not support hiding specific drives. Does not support many of Clover's XCPM patches. Can be resolved by adding an entry in BlessOverride. Does not support auto-detection for many Linux bootloader. Does not support Hardware UUID Injection. Does not support Target Bridge ACPI patching. Does not support P and C state generation for older CPUs. Can be resolved with SSDTTime (opens new window). This can be done manually however: GPU patching (opens new window). Does not support automatic DeviceProperty injection for legacy GPUs. Does not support UEFI-based VBIOS patching. Work around is to chain-load rEFInd once in OpenCore. Does not support booting MBR-based operating systems. The majority of Clover's functionality is actually supported in OpenCore in the form of some quirk, however when transitioning you should pay close attention to OpenCore's missing features as this may or may not affect yourself: Far better stability as there is far less patching involved. OpenCore also supports prelinked kernel (v1, found in 10.4 and 10.5), cacheless, Mkext and KernelCollections, meaning it also has proper support for all Intel versions of OS X/macOS. OS agnostic as the prelinked kernel format has stayed the same since 10.6 (v2), far harder to break support. Rebuilds the cache in the EFI environment with the new kexts. Takes existing prelinked kernel and kexts ready to inject. Now let's take a look at OpenCore's method: Likely to break with macOS 11.0 (Big Sur). Disables SIP and attempts to re-enable it, don't think much needs to be said. OS updates commonly break this patch, like recently with 10.14.4 and 10.15. CLOVER EFI SMBIOS CODE
Calling XNU's zombie code that hasn't been used since 10.7, it's seriously impressive Apple hasn't removed this code yet.Patches race condition with kext injection.Patches to enable XNU's zombie code for kext injection.To better understand OpenCore's kext injection system, we should first look at how Clover works: Have AMD-based hardware? The kernel patches required to boot macOS no longer support Clover – they now only support OpenCore.
CLOVER EFI SMBIOS DRIVERS
Many firmware drivers being merged into OpenCore:.Got a bug with a kext? Many developers including the organization Acidanthera (opens new window) (maker of most of your favorite kexts) won't provide support unless on OpenCore.
CLOVER EFI SMBIOS SOFTWARE
The biggest reason someone may want to switch from other boot loaders is actually software support:
Supports boot hotkey via boot.efi - hold Option or ESC at startup to choose a boot device, Cmd+R to enter Recovery or Cmd+Opt+P+R to reset NVRAM. BootCamp switching and boot device selection are supported by reading NVRAM variables set by Startup Disk, just like a real Mac. 
Vaulting (opens new window) allowing to create EFI snapshots preventing unwanted modifications.No need to disable System Integrity Protection (SIP).
CLOVER EFI SMBIOS UPDATE
AMD OSX patches not needing to update with every minor security update.macOS 10.15.4 update (opens new window).Better overall stability as patches can be much more precise:.On average, OpenCore systems boot faster than those using Clover as less unnecessary patching is done.This includes OSes as far back as 10.4, Tiger, and even the latest builds of 11, Big Sur!.OpenCore now supports more versions of OS X and macOS natively without painful hacks Clover and Chameleon had to implement.Does OpenCore support Windows/Linux booting?.Does OpenCore only support limited versions of macOS?.
Does OpenCore always inject SMBIOS and ACPI data into other OSes?. Getting started with ACPI (opens new window).
