Kernel Panic after upgrading to 10.14.4

I don’t believe it has anything to do with heavy cpu usage - I watch it happen frequently when there are no applications open and I’m not using the machine.

I opened an engineering case a few days ago and referenced this thread. It actually crashed while I was on the phone with them so we have near perfect diagnostic information.

Keep posting information here, hopefully it can be worked out soon. Crash reports are awesome.

Mac Pro (Late 2013)

2.7 GHz 12-Core Intel Xeon E5

64 GB 1866 MHz DDR3

AMD FirePro D300 2048 MB

Here is my mac Pro spec, at first it was panic by SSD and power supply. The Apple rep told me maybe either SSD, Logic board or power supply. So I replaced the SSD and logic board, then became CPU panic. I even put my old SSD and logic board back for running high sierra, no issues at all, that's why I confirmed it's bugs for 10.14.4 or high version.

High Sierra and 10.14.3 are both safe. I will continue to follow up with my engineering case.

From an Apple tech’s perspective, faulty hardware would almost always be the cause of an issue like this and if they haven’t had enough reports to reproduce & document this internally then every tech is starting from scratch. Please don’t fault the techs for doing their jobs.

I wouldnt blame apple if just Genius bar give me run around, but I filed the report at Genius bar and my mac pro was sent to apple service center for diagnostic, my report was cleared on record as running smoothly before update to 10.14.4. Apple service center replied me back with unknown issue but want to charge me 1200 for the fix, I declined it and took it back home. Replaced the SSD and Logic board one by one for testing by myself then finally came out with conclusion. I mean I dont think I'm the only one and 1st one to report this issue, Genius bar doesnt have enough reports for it I understand but Apple service center gets all reports WW and still gave me run around and none exist charges, it's unacceptable. They should do better job for looking into their IOS issues and listen to users even small portion of it. Just my opinions.

I don’t believe it has anything to do with heavy cpu usage - I watch it happen frequently when there are no applications open and I’m not using the machine.

Yes it does. If my MacPro just sits idle it won't panic for hours. If I run a small test application that incurs CPU load on 8 pthreads it crashes within 5 minutes. All OS's after 10.14.3 are affected. 10.14.3 is stable. Booting in safe mode is also stable so it's likely a Kext.

Not exactly... I have the CPU Panics happen in Safe Mode, and sometimes under no workload at all.

Other times I can leave my Mac Pro running for hours, with no issues, even under moderate workload.

so, I think it is a kext, but one of the basic Apple ones, and I think it is related to HW, in that the issues seemed to start when Apple started testing the new Boot version.

Small observation:

I have a small utility running, Little Snitch, and I have it set so it shows up- and download in the taskbar, and when I experience the Panics, right before, the up- and download goes grey (as supposed to red and green), and shows 0 kbps. Then the crash happens...

I don't know if this is a coincidence, but that's what I am seeing...

My Mac Pro is connected to two networks; via Ethernet to my switch and router, and via Thunderbolt to my NAS/DAS.

Bummer. I've been back on 10.14.3 for almost 2 weeks now and am working fine. I am not installing another update or beta release until I see some seriously positive feedback on 6,1 macpro's working properly.

What kernel extensions are people using? Wondering if there's anything common here. To find that information to to terminal and type

kextstat -l |grep -v com.apple

Here is my list:

com.initex.proxifier.macosx.kext 2.23.0

com.logitech.driver.LogiGamingMouseFilter 1

com.driver.LogJoystick 2.0

com.logitech.driver.LogiWheelDriver 1

Any chance we all share something in common? ie, 3rd party RAM?

The only thing custom on mine is a 3rd party RAM upgrade (which I believe might be a tad slower than the original).

I'm skeptical its related since its very specific to the MacOS upgrade ... but ... grasping for straws.

I tried with everything, changed SSD, Logic board, RAMS one by one for testing, all with kernel panic with 10.14.4 or higher version IOS. I'm running high sierra 10.13.6 for like 10 days, everything smooth, not even one kernel panic happens anymore.

I purchased third-party memory in 2014, came up clean when running a diagnostic.

I am having the same issues as all of you. upgraded to 10.14.5 with ROM 130 and still getting panics. Same as some of you its a different panic everytime and support doesn't have any fixes. Run diagnostic which comes back clean and do resets but nothing has fixed it yet.

SkiipV--

The consensus is that this problem correlates with an advanced version of the Boot ROM Firmware -- the two do not seem to be getting along.

There is no evidence of RAM or any other correlations to hardware issues.

On Mac Pro models with Xeon Processor, Error Correction Hardware means RAM issue do not fester. RAM either works absolutely perfectly, or halts with a kernel panic, machine check, status 4 or 5 and detection by multiple processors. Uncorrectable RAM errors are quite distinctive.
