Re: How to migrate from rpi3 to rpi4?

If you have a second SD card available, write a recent raspbian image on it and try to boot that, to make sure that all other parts are working correctly. Then you might retry with your upgraded SD card. If you are using an NOOBS with Raspbian look here https://www.raspberrypi.org/forums/viewtopic.p...

Re: Mac users - booting Buster from SD + HDD

Is this the cmdline.txt as saved on your Mac? The "init=/usr/lib/raspi-config/init_resize.sh" is missing here too, that is commonly present on the original image.
Is the root filesystem extended to use the whole disk by etcher already, or do you need to do it later?

MBR relies on x86 instructions. It is possible to emulate the ones required, but seems pointless. The MBR has an area that is reserved for bootcode. The bootcode should at least start with x86 instructions that avoid unexpected behavior if a x86 system accidentically tries to boot, using this MBR. ...
