Startup Security Utility

Hi try to enable boot from external devices but there is no option, just firmware password. there is an admin account but still no options to allow to see those settings when booting using cmd + R option.

If I setup a password for firmware it works but no other options for allow or disable Secure Boot or External Boot. there are missing from the window. I format, reset and did all kind of troubleshooting but it just does not shows for selection. This is happening in 2019 with T2 chip. Any Help.

Ps. Also try on an MacBook Pro 15"and same thing.

iMac 27" 5K, macOS 10.14

This support article about the T2 chip (published Feb 2019) says it's in the iMac Pro, but doesn't mention the iMac.

(Apple tech specs for both the Pro and the standard iMac don't appear to mention the T2 chip at all.)

A quick way to find out if your iMac has a T2 chip is to hold down your Alt/Option key, click the Apple menu, choose System Information and look under Hardware for Controller or iBridge (this is a MacBook Pro and has Controller):

Cheers,

It is the latest 3.ghz 6 core iMac 2019, so it does have it. Looks like apple did something to the firmware, have a laptop 2017 and it can be disable so boot to an ext drive works, but not with this one, I’ll guess I will take it back to store. This is no aceptable. I should be able to boot from ext source or install a different OS for my work.

Yes thats the screen but does not show the other options, secure boot or external boot, just turn on firmware password. I don't have an option to boot from external devices.

There is no Startup Security Utility. There is a Startup Disk preferences panel that makes a permanent change of the desired startup disk. To make a temporary change then boot while holding down the OPTION key to open the disk manager in which you can choose the desired startup disk.

Do you mean this Startup Security Utility ?

The same one that is used to allow the booting of external drives on Macs with T2 chips?

That one?

Hi, AcostaJose !

I do not believe your Mac has the T2 chip, else it would have a window that looks like the image I posted. If your Mac is under AppleCare protection, I would reach out to AppleCare tech support to get to the bottom of it.

Good Luck !
