Currently Apple has left symbols in place seemingly for debugging purposes however this is a bit worrying as Apple could outright remove symbols in later versions of macOS. This point is the most important part, as this is what we use for kext injection in OpenCore.
Note 2: OpenCore 0.6.3 or newer is required for Secure Boot in Big Sur. Note: ApECID is not required for functionality, and can be skipped if so desired. This is due to the heavy reliance of snapshots for OS updates, as mentioned above and so we highly encourage all users to ensure at minimum SecureBootModel is set to Default or higher. While technically these security features are optional and can be disabled after installation, many features including OS updates will no longer work reliably once disabled. apfs.kext and AppleImage4.kext verify the integrity of these snapshots. OS Snapshots are now verified on each boot to ensure no system volume modifications occurred. ITLWM HACKINTOSH GENERATOR
On Hackintoshes, this will either be automatically generated by your SystemUUID value or manually added with a cryptographically secure random number generator. On regular Macs, the first 8 bytes of your SystemUUID value. On T2's this ECID value is burned into the chip. macOS will now always verify the ECID value to the secure boot manifest files(if present). With regards to Secure Boot, now all officially supported Macs will also now support some form of Secure Boot even if there's no T2 present. Now all Macs will have some form of basic Secure Boot support. All kernels now support Secure Boot(ie. 
Kexts can no longer be hot-loaded, instead requiring a reboot to load with kmutil.And with macOS Big Sur's new Read-only, snapshot based system volume, a new version of caching has be developed: KernelCollections! So for the past 15 years, macOS has been using the Prelinked Kernel as a form of Kernel and Kext caching. New Kernel Cache system: KernelCollections! Quite a few things actually! Both in good and bad ways unfortunately.

Disabling macOS snapshots for the root volume with break software updates, and can corrupt data if one is applied.OS snapshots are not calculated as used space, instead being labeled as purgeable space.However there are a few things to note with this new enforcement of snapshotting:
ITLWM HACKINTOSH PLUS
Time Machine can now more easily perform backups, without file inconsistencies with HFS Plus while you were using the machines. OS updates can now be installed while you're using the OS, similar to how iOS handles updates. 3rd parties have a much more difficult time modifying the system volume, allowing for greater security. You can check out Apple's site to get a better idea:Ī feature initially baked into APFS back in 2017 with the release of macOS 10.13, High Sierra, now macOS's main System volume has become both read-only and snapshotted. ITLWM HACKINTOSH MAC
Love it or hate it, we've got a new UI more reminiscent of iOS 14 with hints of skeuomorphism(A somewhat subtle call back to previous mac UIs which have neat details in the icons) What has changed on the surface A whole new iOS-like UI With Big Sur, there could be 3rd party GPUs however the chances are still super slim but slightly higher than with 10.14 and 10.15.
ITLWM HACKINTOSH DRIVERS
What I mean is that secure boot cannot work with Nvidia's Web Drivers due to how early Nvidia's drivers have to initialize at, and thus Apple refused to sign the binaries. Why this is relevant is due to Apple's initial reason for killing off Web Drivers: Secure boot. However macOS 11 makes some interesting changes to the boot process, specifically moving GPU drivers into stage 2 of booting.
Currently Nvidia's Kepler line is the only natively supported gen. Sadly every year I have to answer the obligatory question, no there is no new Nvidia support.
Death of x86 and the future of Hackintoshing. Clover's revival? A frankenstein of a bootloader. Dortania: a new organization has appeared. Legacy GPU Patches currently unavailable. New Kernel cache system: KernelCollections!. It's that time of year again, and we've got a new version of macOS on our hands! This year we've finally jumped off the 10.xx naming scheme and now going to 11! And with that, a lot has changed under the hood in macOS.Īs with previous years, we'll be going over what's changed in macOS and what you should be aware of as a macOS and Hackintosh enthusiast.
