I’ve an previous mac guide air 2015. I just lately put in Linux Ubuntu 2024 on it on a brand new ext4 partition. I can twin boot between macOS 12 and Ubuntu when ever I would like by holding choice key on startup. Since all my household makes use of this mac I would like the boot precedence to remain on macOS, so my household does not should take care of twin booting choices at startup. I do know I can set startup disk in macOS system preferences and I additionally use efibootmgr -o xxxx,yyyy on Linux to alter this boot order, however the issue is any time I change from macOS to Ubuntu from the startup disk chooser ( by holding choices key on startup), the boot order is about again to Ubutnu partition, so I’ve to alter this order once more after I end my work. Is there any method to change this conduct in order that boot precedence is at all times macOS it doesn’t matter what the final used OS is? I dunno if it is a mac particular factor or ubuntu so I am posting it in each communities.
