... in iOS 13....

Forget to mention: when you start with this kind of procedures I always boot in Recovery Mode and make a full image via Disk Utility to an external disk!!!
I have used in the past also Carbo Copy Cloner but an image contains also your EFI and firmware setting. Never had any problems restoring an image.

My two cents.

        Folks:
        I have a bit of a worry about the Apple Catalina update. I want to keep a bootable copy of the latest Mojave OS on an external disc. That way I can run any older 32 bit programs I might need. However, I have a backup program (Tri-Backup) that says it can’t make a bootable drive because of Apple security. That has raised a bit of a red flag to me. 

        Currently, I use SuperDuper to make a bootable backup. SuperDuper isn’t updated for Catalina yet, it seems.

        What my worry is, is that perhaps Catalina’s new security settings won’t allow booting from an external drive. That would completely eliminate my option of having a 32 bit OS option for running older 32 bit software.

        Anybody have any info relevant to this issue? Or perhaps I’m just being paranoid (totally justifiably).
        Best,
        Bill

        PS: sorry if this is a duplicate.

Since the introduction of Apple's  T2 Security Chip it isn't possible to boot Linux on new Apple hardware like the 2018 MacBook Pro and Mac Mini anymore as far as I know.

My experience says that ALL OS systems/devices break bar none unless they don’t update at all and stay stagnant. So which system do you prefer JJS? And remember only to mention one that is completely infallible and never likely to break. Id especially love to know a device name that is completely 100% future proof I can pitch to my customers. As yet, the ‘most’ reliable I have found from a whole heap of testing and long term experience are iPad Pro and Macs. Even my ipad2 is shockingly more reliable than any of my top end Samsung tabs (unless I strip them right down and use custom OS).

Roids way of avoiding breaking is to only offer minor device OS updates and expect you to bin old devices after a couple of years (apposed to the 6-8years for Apple).
