Ubuntu 26.04 on a 2013 MacBook Air

I recently came into possession of a 2013 MacBook Air, model A1466. Nothing out of the ordinary with the Ubuntu Desktop installation but when I restarted I was confronted with the flashing-folder-with-a-question-mark problem. After a little research I discovered that there is a quirk with this model's UEFI. The solution was to manually partition the drive during installation.

 

 

• Erase the existing drive.
• Select the relevant SSD as the 'Device for boot loader installation.'
• Create a partition with remaining free space.
• Install. 

Problem solved and this ancient MacBook works great!
