You can manually manage partitions as part of the custom install step.

On this page, select "Custom Install"

Then select "Modify Partitions" in the bottom corner

After modifying partitions and applying changes, you can either proceed with a custom install or go back and try a standard install when the disk has been erased

Can "Modify Partitions" remove the MacOS X Base System partition? I can't get the intel Mac with i5 processor to launch elementary 8.0

It just launches GParted and I've successfully clean installed elementary OS 8 on my MacBook Air 2010 for many times so I think yes.

Is your Mac able to boot elementary OS 8 from an installation media but isn't possible to boot from SSD, right? If so I think you can check if the OS X Base System partition disappears or still alive by booting from the installation media again and launching GParted.
