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
