Just to keep the record current: Recent macs with T2 chips do use secure
boot, see
https://www.omgubuntu.co.uk/2018/11/apple-t2-chip-cant-boot-linux quotes
Apple:

NOTE: There is currently no trust provided for the Microsoft Corporation
UEFI CA 2011, which would allow verification of code signed by Microsoft

bootloaders for other operating systems such as Linux variants.
