iMac pro constantly crashes under load

My iMac pro constantly crashes under load while working and randomly restarts entirely or freezes and needs a hard restart. Almost a daily problem. It has the T2 security chip , I’ve read plenty post from others with the same issues regarding constant panics and the T2 chip I’m experiencing it every day, and I can’t afford to have it sent away as it’s my main working computer. Anyone else have this problem and how was it resolved. Repairs, new computer? Just checking before I waste more of my time with the most expensive unreliable computer I’ve ever owned....,

iMac Pro, macOS 10.14

Hi,

I assume your iMac Pro has software related problem, though it's worth running Apple Diagnostics if it reports something.

https://support.apple.com/en-us/HT202731

If it doesn't report anything, then boot in Safe mode to isolate issues with your Mac.

If you don't have any crash, third party kexts which you installed might be the problem.

If doesn't help above, run Etrecheck and paste the result here.

Also paste the crash report which is located /Library/Logs/DiagnosticReports.

In addition to what has already been posted here (and if the diagnostic especially shows up as clear) this is what I also suggest:


Create a new partition using some of the free space on your hard drive via Disk Utility. You could create a new additional (2nd) partition with say, 30 gb. Boot up into Recovery (COMMAND-R) on startup and install a fresh copy of macOS Mojave onto that new 30gb partition. You can then dual boot (holding the OPTION key) on startup between your current install of macOS, and this new install.


Once you do this you can see if your macOS still continues to crash or if this fresh Mojave works perfect. If it continues to crash, you almost certainly have a hardware problem. If it works perfectly then the issue is software or macOS related and getting it shipped off for repair would be a waste of time.


If you are in the US (or certain other countries) and are still within your 1-year warranty you would be eligible to buy AppleCare+ Protection Plan (if you don't already have it). With AppleCare+ you would be entitled to onsite repair service if some hardware component needed to be replaced.

A large number of Pro users report frequent crashes and kernel panics on the latest iMac Pros.


This has been traced to the T2 chip and Bridge OS which is software that handles the T2 chip.


macOS 10.14.5 was supposed to fix the kernel panics but has not been entirely successful. This is a problem of Apple's creation. Make Apple fix it whilst you are still under warranty, Apple has a history of making users think they are the ones who should fix the unfixable, and Apple sweeps the problem under the carpet until it is too late for the users.


You have paid handsomely for Apple's products, make Apple live up to its hype and make Apple fix the problem or replace your purchase with one that works. If they can not do that, demand a refund.

Here is one of the most recent.... Im in photoshop 99 percent of the time when Im on my computer but honestly anytime Im using a program like Corel Painter, Imovie or anything that is taxing on the system, I get the same crash results.... spinning rainbow and then either total program crash or lock out where I have to do a hard restart.

I used my other normal Imac for years without a crash ever. Its amazing to me that I upgrade to the Imac Pro that is custom built for these types of graphics intense programs and it runs horrible and crashes on a daily. So frustrating. I loved my Imac and the stability of it was amazing, just cant figure out why my newer Imac Pro is such a piece of junk and so unreliable....

Here is the data from the last crash. I have dozens in the report.... should I share more?
