macOS big sur, macOS Monterey black apple installation pops up an update assistant and then prompts that the required firmware update cannot be installed.
OpenCore boot workaround:
1.config.plist — PlatformInfo — Generic, replace with a newer SMBIOS model;
2.config.plist — PlatformInfo — Generic 勾选 AdviseFeatures；
Then save and restart.
In the past two days, I helped a colleague install WIN10 dual system on a MAC BOOK AIR (2015). When selecting the system partition, the prompt "On the efi system, windows can only be installed to the gpt partition" appeared. I found many ways on the Internet. None resolved. Later, using a netizen's method, the installation was successfully completed.
Solution:
1. Use bootcamp to adjust the win10 installation partition in MAC OS.
2. Use Disk Utility to erase the newly partitioned area, and select the partition format as mac journal (remember! I have taken many detours here)!
3. Restart the computer and press and hold the option key to select the U disk or CD (the U disk or CD for WIN10 installation has been created in advance) to start.
4. Enter the installation, delete this disk when selecting a disk, and then create a new disk!
5. Then follow the prompts to install.

When EFI is booting, it will first check whether there are " bootmgr.efi " and folder "efi" in the boot medium.
This is the key point.
Once the boot media does not have these two files or folders, it will default to the traditional BIOS method to boot, so there is no emphasis on the GPT partition.
That is, we can install the Windows 10 system normally.
How to do it:
Delete the file "bootmgr.efi" and the folder "efi".

Solution 3: Repair the type of EFI partition
The boss of this article gave a solution
According to the big guy, the cause of the error is that the partition type GUID of the MacOS startup disk is set to a wrong value after the partition is operated under Win10.
The main step of the solution is to modify the partition type GUID of the MacOS disk to the correct value through the command line.
Partition type GUID Description
48465300-0000-11AA-AA11-00306543ECAC HFS+
7C3457EF-0000-11AA-AA11-00306543ECAC APFS (unencrypted)
command line code
(if it doesn’t work under Win10, you can try to enter repair mode)
(requires administrator privileges )
list disk
select disk 0
list partition
select partition 2
set id=7C3457EF-0000-11AA-AA11-00306543ECAC
上一行是针对apfs磁盘类型，hfs+相应修改下
