Can't you boot from an external drive (time machine backup) using option, on Catalina? I was under the impression booting from external USB was how you would format the mac.
I don't know about time machine. I suspect you might.
To be clear, I wasn't saying they were taking out the option boot-picker.
I was saying these lesser known features - although they will never be used by a general audience - make the mac significantly easier to administer for people who have been using macs for years and know what they're doing.
I will say I'm glad you can upgrade an older system to a new usb-c style thunderbolt machine using target disk mode - but the dongles/cables to achieve this feat are ridiculous.
