is it working on 15.1? I've had it. taking it into Genius Bar. Let these people earn their money. It can stay there for a month. Maybe it will force them to admit there is a problem. Restarting over and over. Did install from recovery mode 2x. Fail.

Yes sequoia works up until 15.2 which breaks owc drives so 15.1.1 is the latest working
 
Do not update to 15.2 everyone!!

It’s brought back the original issue of startup hangs and raid drives not mounting again 😩😩😩!!!

Damn, just did… didn’t see the issue yesterday.

How can Apple be so bad at this! Or is it a deliberate feature improvement to annoy evil 7,1 users who refuse to buy newer machines…

I have a Sonnet card so fingers crossed.

PLUS most importantly people RARELY bring their MAC PRO into the Apple Store to get fixed, so it's likely the biggest reason it's not a known issue. I brought mine in today, and told them fix it, and left. Who knows what they will do, but i gave them an opportunity to own it, after two years of this. While I have been a Mac user since 1985, I may have to switch back to PC, like I had to in 1998.

A waste of time, the only answer those condescending nitwits have is ‘reinstall your operating system’.

Yes, this is truly unbelievable. I wasted many hours on this today, could not do any work because most of my stuff is on an OWC Thunderbay 6 with SoftRaid. I have a PhD in ICT & have working with most OS for over thirty years, and then we still get this garbage from Apple, then condescending Bs via phone support or self-proclaimed ‘genius’.

In any case, FWIW - I found a lot of this out there on Apple fora, many many users (zero answers from Apple). Primary workaround appears to be ‘boot with thunderbay off’ then turn on, this appears to work.

Another recommendation is to install 15.2 while the Thunderbay is off, yet to verify & am currently time-wasting again & re-installing from recovery to see how that goes (I ‘could’ have rolled back to 15.1.1 from a CCC image, but that is sitting on a Thunderbay m.2; well done Apple, you certainly did your homework on how to best f-us).

See eg, https://discussions.apple.com/thread/255883440?sortBy=rank

Re PCIE RAID, so happens that my Sonnet 4x still mounted (go figure) but following the prior logic, one would have to pull the card, update the OS, then install the card again - only conjecture here.

Bloody BS & Apple incompetence /lack of customer care. I wonder how many lost income dollars out there?

On my 28 core machine (the single W6800 one) having no issues so far using 15.2 (24C100) with a Sonnet card thankfully.

I have to say this is exactly my experience with not just the Genius bar but almost every high ranking contributor that comments on the, (Un???), Official Apple forum.

The Apple forums do seem populated almost entirely by "i understand you're trying to do (x), have you considered that Apple product always work perfectly, and your expectations are at fault?"

I had that experience on the Apple forum as well, I scolded one of the high ranking "experts" on there. He was just trotting out the boilerplate response. Didn't go back to see what his response was.

It's always the fault of the customer, never the fault of holy Apple who can never ever do wrong. You get the same around these forums at times as well but not nearly as bad.

It's actually the reason I left the place years ago.
Whe I was new to Mac I googled, found the ASF and naturally thought it was the place to go for Mac related support. Was contrived and awful.
Had a 'disagreement' with a guy I think was called CSound1, (and one other that escapes me now), and that was the point that made me want to leave it.
 
I have a MacPro 7,1 with an OWC Thunderbay 4 in RAID 5 configuration that was neutered by Sequoia 15.1, but started to work correctly again (as reported by OWC https://eshop.macsales.com/blog/964...n=cj&cjevent=254b50fcbcb911ef83ecec100a82b836), when I upgraded to 15.2.
Unfortunately, the problem has returned. Yesterday the Thunderbay SATA drives disappeared along with two other HDD drives attached via an OWC "Toaster" via USB-3.
The good news is that a PRAM reset recommended by Apple Support solved the problem and all the drives came back. And now the bad news, I turned the machine off overnight but upon rebooting (several times) today, the drives again had disappeared. Several PRAM resets did noting to bring them back.
I also have SoftRAID installed and that cannot see the drives either.
OWC was active in working with Apple to resolve the problems, but it looks like we need to let them know that the problem has returned.

Just wanted to update this thread to say I haven't had this issue again with the drives failing to mount on OSX since doing a backup of all my PCIe drives, wiping and Raiding through Softraid. Suggests it was defintely something going wrong when creating Raid0 through the native OSX Disk Utility.
Bascially, I had to buy an expensive Softraid license so that I had full support for my different PCIe drive adapters to solve the issue.
Which operating system did you begin with when you bought your seven, one?
 
Unfortunately, I am in a restart loop since upgrading to 15.2. They are telling me to remove the raid on my M.2 drive and that I should delete the main drive and reinstall the operating system. After I do that if I install software, do you think it may be able to see the data?

So I had an Amfeltec squid that was NOT showing up at all. So I moved my SSD's over to Highpoint 7101A and I see the NVMEs but they are not mounting. Disk utility and SoftRaid do not see them. Bueller?
Whoops. Looks like I was wrong. Highpoint update drivers fixed it on 15.2. Fingers crossed this stays working. At the very least I confirmed there was no data I was dying to have on there. 04/23 is the last time I can confirm it worked. Odd the Highpoint works, and amfeltec squid does not show up. I wonder if it's the Broadcom bridge which I believe is the 8732 on Amfeltec? I am less than confident the Highpoint will keep working, so low expectations and high acceptance. Fear. Turning off MacOS updates forever pretty much. (from highpoint thread where I posted this)
 
Hmm, so someone correct me if I'm wrong, but IIRC slots 5-8 (counting up from the bottom) are the PCI Switched slots?

@flowrider has stable booting / mounting in slot 5, @ZombiePhysicist in 5 or 6 (6 being the x8 slot, 5 the x16)...

Might rule out the PCI switch as being inherently the problem... Maybe Highpoint does something different - Broadcom chipsets (they make a big deal about them in their marketing material) - that doesn't suffer whatever this problem is?
I wonder if a lot of this is due to the what appears to be that Apple is dropping support or seems to be dropping support for Broadcom and I wonder if the problem we are having has something to do with that. I was reading somewhere that this may have some thing or everything to do with Broadcom chips and their Wi-Fi and Hackintosh.

I think it's got more to do with iPads not having PCI slots, and NVME storage as a concept, and the Mac now just being a UI theme / permissions level. Everything flows from that.
 
Mac Pro 2019 + Afterburner
Hey, off-topic but I see you mention the Afterburner in your signature. Can you tell me more about how to best pair the Afterburner I just got to go in my 2019? I have the 5700 and the 5500 due to the way my deal from Ipower-resale came together, so unless I end up with more monitors, it seems like I might as well remove the 5500 and put the afterburner in its spot leaving more room above for the various nvme space I want to retain.

Thoughts? Most of my work will be intensive lightroom/Photoshop/Capture One and some video but probably never more than 3 monitors though one or two will be 5k and the other an older HD 30" Apple cinema display.

Nope, Thunderbay 6 here, SoftRAID, OS 15.2. same *****, different day.

Honestly, I only have mine in the machine because removing it is too much of a palaver. The Afterburner (AFAIK) has one function - decoding video for playback. If you're not editing video, it's largely a paperweight. It doesn't help with display functions or *encoding* etc, merely means you can have more streams of higher quality realtime video in your editor.

If you have it in a PCI x16 slot, it will use 16 lanes, and can process (IIRC) 8 streams of video. If you put it in an 8x slot, all that happens is the number of streams is halved. IF I keep mine in my machine, I'll probably end up moving it to an 8x slot, so my NVME card can go to the x16 and be fully populated at its full capacity.

The W5700 can drive all your displays on its own. The real question it what you want in your second MPX bay, with all that unswitched PCI bandwidth.

Aferburner is even more limted than that: only ProRes codec & somthing not all that common in cameras. A good Nvidia would have nailed it, but oh …. Useless except for a specialised & questionable workflow. Yet another dubious brain fart & misrepresentation from Apple.
