[SOLVED] How can I disable secure boot on my MacBook Pro 2011?

[leon1912]

Hello,
today I tried to install Ubuntu on my MacBook but when I start from the USB-stick, an error appears and it says that I the system cannot boot from the stick because of secure boot.
How can I disable that?
I have already tried to do it at Disk Utilities on Startup Secure Utility but on this menu, I can just add an firmware password.

Sorry for the bad English and have a great day!

Best regards
Leon

that applies to Mac's with a T2 Chip. the 2011 MBP does not have one.

What version of Ubuntu? i had a 2011 MBP and it installed Ubuntu without needing to disable this...
