One more thought (because these case studies occasionally turn out to be
useful to people) is that the SSD start-up had complained it was full
not that long before all this (day before, I think) and it was full of
temp files so I restarted and deleted a few bits and pieces. The
directory may have got muddled at that point, I'm thinking....

Yeah, I have the old graphics card so could replace the new one and
run the test (it's just very fiddly to connect the cables with my
eyesight being a bit old, and I've been trying to avoid it!).
Annoyingly it won't do anything at all on any OS with both left
installed.
And I had the same thought after looking at the Mac mini spec- I could
get a thunderbolt 3 enclosure. My main need is not the power (having
five disk bays is nice though!) it's multiple monitors and I was
surprised to see a mac mini can drive three with the right
attachments. It can also get really expensive if you max it out!
But I didn't want to buy anything until the apple chip versions came
out...
Thanks Sam. I did think the new ones were locked down, as it were but
wanted to double-check.
cheers,
Jason

Can you try with a different graphics card to test? You can buy a
replacement then send it back if it doesn’t resolve the issue.
I believe the new MacMinis are all soldered PCIe storage these days,
they don’t have a SATA port anymore. You could connect your SSD via
a USB3 enclosure and it would be almost the same speed as in your
MacPro.

Hi smuggers,
I've never seen a problem like this. My old Mac Pro, with an
upgraded graphics card that supports Metal in Mojave has suddenly
started failing to launch apps but only some apps. It started on
Friday when I was in the middle of doing stuff, and it was behaving
normally, then suddenly it wasn't.
Eg it starts up normally but then apps that normally take a few
seconds take about 20 minutes to launch (no exaggeration). Once
launched, they might or might not work normally. Virtually every app
does this but not all - eg Activity Monitor behaves completely
normally, starts up in a few seconds. Safari, which launches after
about 3 or 4 minutes, quits in a second when I tell it to, but other
apps get stuck and never quit. The Finder is meanwhile normally
responsive, eg copying a 6 gig file to a USB drive in a couple of
minutes.
I've run an ancient copy of Rember (RAM checker), and done the
Crucial 'garbage disposal' thing by starting up in Target Disk Mode
and leaving it for 8 hours.
What makes it difficult is that because of the new graphics card,
that let it run Mojave, does not display the usual 'hold down a key
at start-up' options such as hardware test or selecting start-up
disk. Holding down Shift for Safe Mode seemed to just make it hang
indefinitely forcing a hard shutdown.
The start up is an SSD connected via PCIE card. So tomorrow I'm
going to try removing each of the 8 gig RAM sticks and seeing if
that eliminates it, then connecting the SSD into one of the internal
bays (it was a bit slow generally doing this but would point at the
PCIE card). I'll also try to create a Mojave start-up but
annoyingly, despite the upgraded graphics card, trying to run the
Mojave combo refuses to launch as it thinks my graphics card doesn't
support Mojave.
All of which makes me think maybe it's time to replace it if I can't
work this out. I can only afford a Mac Mini but the entry level has
a puny 256 internal start-up. How hard is it to swap that out for my
existing 2.5" SSD (if possible at all?)
If anyone can think of anything else to try, please let me know.
I've run Disk Utility and am considering if I can erase and restore
the SDD as HFS+ so that diskwarrior will play nice with it. I've
also removed and re-seated the RAM after carefully vacuuming out the
internals.
Cheers,
Jason
