I did a test run on my M1 Mac mini (I get nervous when I don't have a
spare boot disk) and it sort of worked but there was a massive
performance hit (I think there were websites saying you couldn't
actually do it, so maybe I got lucky).
What I've done is set up the SSD as the full boot disk then sync via
Superduper to the internal drive so if something goes wrong, it will
start up just as you left it at the last backup.
I think 'start up from an SSD' is going to be one of those things that
is great for a few years then becomes obsolete.
Anyone remember RAM disks from OS 9?;) They were great for extending
battery life (up to 6 hours!).
cheers,

For what it’s worth, I downloaded Mac OS (not the latest Big Sur
unfortunately) to a 1tb ssd for my 2012 with 3tb fusion drive. If I
can do it anyone can! I boot off of the ssd and it works perfectly.
Easy to do and worth doing

I've had decent results from starting older macs from SSDs even with
USB 2 so it's worth a try as with USB 3 or 4/thunderbolt it ought to
be okay.
As for shares, I remember wondering about buyng a few (have never
bought shares) in about 1997, when they were $11 IIRC!
I've pretty much settled into only upgrading a macOS once or twice,
then putting it off. The performance hit is too great even when they
are supported officially. And I've learned to buy more RAM than I
imagined I could ever need, as even with swap to SSD you notice the
difference.

Thanks, Paul. That's helpful. Don't think I'll risk upgrading my iMac
as whilst it's just about young enough it has a Fusion Drive and it's
struggled of late which is a shame. One day I think I'll make an
external SSD the boot disk. Oh, to make time to find time for such
fun!
I think WWDC22 has been encouraging and certainly the software
updates look really good and Mac hardware also back on track.
If only I had bought those shares back in 1997 ;)
But looking forward to hitting 'update' in the not too distant future
at least!

This page gives all the supported devices for the upcoming Venture
and iOS, 16 etc. I just about scrape by with all my devices, even my
iPhone X which is a nice surprise. In general it appears any Mac
built before 2017 will not be compatible.
The list is different to which Macs supported Monterey, so don’t
think because you’re running Monterey you can necessarily run
Ventura.
