Apple's T2 Chip May Be Causing Issues In iMac Pro, 2018 MacBook Pros (digitaltrends.com)
According to Digital Trends, the T2 chip that enables things like secure boot, better encrypted storage, and "Hey Siri" support may be causing problems in MacBook Pro and iMac Pro computers. From the report: Many iMac Pro owners have reportedly suffered numerous kernel panics -- the MacOS version of the dreaded Blue Screen of Death in Windows -- since they hit the market at the end of 2017. You can find a handful of threads on Apple's community forums, including this one, detailing the trials and tribulations customers are experiencing with their expensive iMac Pros and Apple support. The problems apparently reside in the new MacBook Pro laptops, too. Of all the error messages uploaded to these threads, there is one detail they seem to share: Bridge OS. This is an embedded operating system used by Apple's stand-alone T2 security chip, which provides the iMac Pro with a secure boot, encrypted storage, live "Hey Siri" commands, and so on. It's now included in the new 2018 models of the 13- and 15-inch MacBook Pro with Touch Bar. But whether the T2 chip is behind all the kernel panics is up in the air. The symptoms and solutions are varied across complaints, such as iMac Pro owners daisy-chaining storage devices seeing crashes along with those with nothing connected at all. But Apple is aware of the problems and is apparently working on the issue behind the scenes. While Apple is replacing these machines, the problems still seem to occur on the new hardware. This latest controversy comes hot on the heels of the last MacBook Pro controversy about overheating concerns.
LOL !!
I've had various kernel panics since Yosemite....caused by (seem to be) things such as Thunderbolt Raid, Ethernet, Sleep Wake and Raid...I wonder if I need a new machine, or to take the Macbook Pro in for service. Eventually, Apple issued an OS revision and the problem goes away (until a future OS update). It is unfortunate that it is hard to tell where the problem lies unless apple admts it.
I just doesn't work!

A workstation (desktop or portable) should always focus on proper cooling and performance specs even if it means making it thicker or adding another air duct.
These things are supposed to be trucks - Apple needs to start acting like it.
MacOS really needs a complete rewrite from the ground up. At this point it is a Frankenstein pastiche of this and that culled from here and there. It's architecture has long been eclipsed, a cousin to GNU Hurd, and just as ancient. Apple engineers have kept things afloat with some pretty good hacks. But they are hacks nonetheless.
MacOS is long in the tooth, and chock full of ugliness. It is time to start over with a clean new 21st century design.
”This is an embedded operating system used by Apple's stand-alone T2 security chip, which provides the iMac Pro with a secure boot, encrypted storage, live "Hey Siri" commands, and so on.”
Perhaps the T2 chips intentionally trigger kernel panics because they find Siri as aggravating as the rest of us do.

Back in 2006 all the iMacs I saw with that tiny little vent overheated constantly in any ambient temp above 75F. Then there was the iphones and their death hold, touch death, sapphire lens purple flare, bending, battery issues, artificial performance degradation, purposeful bricking due to 3rd party hardware. Then there's the macbook that can't run at the speed they claim under any circumstances other than inside a freezer because they made it too thin. Now their rushed-out unnecessary feature chip is failing. It's almost like Apple never has made good products and never will. Why can't anyone else see this pattern?
next mac pro needs to have storage that is not locked to the MB or locked into apples choices.
Forced raid 0 is an no go even more so 2 pci-e cards stuck behide an X4 pci-e link.
maybe along the lines of trying to save Steve Jobs via time travel, etc.

No one using a Mac Pro or an iMac Pro is going to be storing data files on the internal storage; the files they typically work on are entirely too huge. Those users typically use SANs or big external RAIDs.
So an internal RAID is a pretty silly thing on Pro machines.
Have you tried spending money on a Linux Desktop/Laptop?
Linux from Dell is pricey but that's what rich people use.
That is quite crazy. 4k RAW video is still only a couple of TB. I've seen Mac Pro users mostly working with internal storage. It goes the same with my Windows Autocad station with SSD RAID5. It is faster than most SANs since SAN connections are limited by edge connectivity which is 10gig at best unless people are putting in 16 or 32gig fibre channel direct to a desk but most people don't do that. When we built our office I saw fit to future proof the wiring so there is single mode fiber in the graphics department so we are able but with both SANs being iSCSI again you're limited to 10gig.
Every high-end workstation I encounter does the same thing. They pull their working files down, do their thing, then copy them back up. It is usually quicker to work local.
... it just keeps getting worse. My 2017 macbook pro likes to turn of the magical touch strip. Comes back on if you reboot, but...
I really don't want to go back to windows... maybe I'll have another run at linux. It's been 10 years, and it was almost tolerable on the desktop back then.
Gonna miss this sexy lookin package though.
And take your business elsewhere.
Thanks explains a lot. You are just good old fashion stupid.
internal RAID 1 better then raid 0 or even
multi disk setup with
OS Disk
Archive Storage / Backup disk
scratch disk / temp work disk.
You're operating on anecdotes and confirmation bias, which together can be used to prove just about anything. But Apple has been at or near the top of hardware reliability survey's since the Precambrian age of computing.
I have yet to see a Macbook Pro in my vicinity.
Seems since the release of the A1502, things have just gone downhill. Losing useful/viable ports and declining options for repairs (both consumer and microsoldering). The MBPro Retina 13" / A1502 covered all areas well, and you could still change your SSD and still connect to items without requiring dongles. We should have seen Apple bring out the next one with USB C + USB A (3.x) but instead we ended up losing everything, even the laptop-saving magsafe.
Likewise on the iPhone market, iPhone 6S/6S+ was mostly the peak in balance, but since then the devices have become increasingly difficult to repair.
The GPU overheated, and their logic board replacement program used logic boards that had the same problem, so eventually the replacements would have damaged GPUs too.
After seeing all the trouble the T2 caused to John Connor, it doesn't surprise me.
