Preparation: a free USB disk or mobile solid state or mechanical, find the efi that suits you through your own machine model (it is recommended to find the opencore boot file, adding windows and Linux boot will be particularly easy, it is easy to achieve MacOs+Windows+Linux multi-system booting at the same time )
1. First compress a partition with a suitable size and format the file system as APFS
It is recommended to use Paragon Hard Disk Manager 16
According to the above picture, select the partition where the mac will be installed and wait for success as shown in the picture.
2. Then burn the installation disk, TransMac or etcher burn the installation disk
TransMac
Convert the file format of the removable disk to be burned to the installation disk to Mac
When a warning appears, select yes
Give the u disk a name, easy to find when booting from the u disk
The blogger installed BigSur here, just name BigSur
After clicking ok in the previous step, it will remind you to overwrite the disk data and continue to click yes
Finally, Format Complete appears, indicating that the format conversion is successful
Continue to the installation disk to be made, select Restore with Disk Image
Click the button in the image below
Select the downloaded dmg mirror, select it and click to open
Then click ok
Choose yes
Start writing to the mirror
Writing progress:
Waiting for the progress to be completed, you can restart the computer and select the USB flash drive to install
etcher
Trilogy: select mirror, select the disk to be written, and click start.
Wait for progress to complete
…
After burning successfully, as shown in the figure:
3. Mount the efi partition of the burned installation disk and replace the efi suitable for your machine
The second part is just to complete the production of the installation disk, but there is a small chance that the installation can be successful directly, so you need to replace the installation disk with the efi boot file suitable for your machine, so the chance of successful installation will be very large. The fixed logic thing is successful Can be copied.
Mount the efi partition through diskpart , or use DiskGenius partition assistant to directly find the efi partition and replace the efi file that is suitable for the hardware of your machine.
Use opencore to boot, only need to replace the oc file in the efi file in the efi partition
Fourth, the system installation link
There is no video capture card and no pixel-touching equipment to shoot the installation process, just briefly describe
Restart the system, press the start interrupt button 1 crazily when you just start the system, the author dell is F12, and then select the u disk to start the follow-up installation
The installation is extremely simple. You only need to confirm that the selected partition is the partition or the entire disk that you have planned and converted the file system to APFS. It will not affect any existing systems on the computer. Fool-style installation. There will be several restarts in the middle. Will enter the opencore boot interface, the installation process is the default carriage return, the installation will be successful, don’t forget to show off when you enter the mac system
Be careful not to shut down in a hurry. The first case is that the machine already has a windows system: remember to copy the OC file in the efi in the USB disk to the EFI file in the original EFI partition of the computer, configure the windows boot information for opencore, and restart it. BISO sets opencore as the first startup item, and you can boot multiple systems at the same time. If there are linux coexisting, more operations are needed. Follow-up instructions
The second case is simpler. If you only install the black apple to monopolize the computer hardware, you only need to reboot into the BIOS and set oc as the first startup item.
In the third case, MacOs+Linux needs to use tools to add boot
