Install Mac OS X On legacy MacBook Pro 2011

After I click the “Upgrade” in the old MacBook Pro 2011, High Sierra, after upgrade for a while, then I saw the blue screen, waiting for a long time, it’s still show the blue screen.

Try force reboot, with “Option” key, it has options

1. EFI BOOT
2. Mac OS X Install
3. Max OS X

I have try all of them, [1] will show some errors with some text, [2] & [3] will show the same blue screen.

Then also tried

1. Recovery Mode, doesn’t work
2. Network Recovery Mode, doesn’t work
3. Hardware test, seems check passed.
4. CMD+v, verbose mode, it works.

It doesn’t work on my new M1 MacBook Pro 2021.

Found kind of solution like this, doesn’t work.

cd /Applications/Install\ macOS\ Mojave.app/Contents/Resources/

codesign -s - -f createinstallmedia

Convert dmg to iso

Finally try convert dmg to iso, and burn it with “dd”

hdiutil convert InstallMacOSX.dmg -format UDTO -o InstallMacOSX.iso
mv InstallMacOSX.iso.cdr InstallMacOSX.iso
sudo dd bs=8m if=InstallMacOSX.iso of=/dev/disk6

Still doesn’t work, blue screen.
