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.

that seems indeed the problem. As you know, running macOS from Hackintosh’s,
Security Boot must be disabled so as SIP (because of patching during boot). I
have not test yet to install Linux on my MacBook Pro though.

likely it is only a tiny update for Monte to fix. 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).

unfair and exaggerated. They break for sure, but not to the extent to ‘refuse’
it. 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).

never heard of backwards compatibility. If someone wants Apple or iOs, just
refuse it. To much hassle, and costs to much.
