Kernel Panic after upgrading to 10.14.4

Unrelated question..

How would one go about learning about some of these things? Experience or..?

Yes. Same goes for me. Mac Pro has been on since the update and not a single KP happened so far. Finally!!

Anyone on this thread brave enough to try Catalina beta yet ?

I did, by mistake.

Luckily so far so good.

I have been running all day everyday without shutting down (computer only restarted for recent MacOS update). Everything has been smooth and no panics. I hope this stays until Catalina update.

Thanks for the heads up. Plan to install over the weekend.

It works fine if you boot up in Safe Mode, but then of course the machine isn't really usable. So now it's a matter of swapping out 300+ System extensions to see which one is the culprit... I wish Apple wouldn't make it so hard to revert back to a previous OS... once you have 10.14.4 installed there is no way how you can get back to 10.14.3 except a cloned copy of the previous system :(

Same problems here ... Mac Pro with 129.0.0.0, kernel panics started with 10.14.4

Most common (but not always):

Panic(CPU 19, time 32198753185467): NMIPI for unresponsive processor: TLB flush timeout, TLB state:0x0

Unfortunately I also updated drivers for a Lacie Big12 RAID box at the same time -- creating confusion on what was the source of the problem. Spent a lot of time reinstalling fresh to have the same problems persisting.

Mac Pro 2013, 8 core user.

I'm a photography and videography, since update to 10.14.4 or even I had clean install, but constantly crashing with kernel panics when using:

1.) Canon Digital Photo Professional when batch process photos

2.) Adobe Premiere

3.) Time Machine (fixed with clean rebuilt)

Screen flickering when using Chrome browser

System report to apple but no response and call apple support but no one can help or known this issue.

Thank you.

I wiped my SSD and put a fresh copy of 10.14.3 back on my 6,1 MacPro. This has been stable for 5 days now, no issues. I have done a lot of stress testing, and have Thunderbolt 2 as well as Thunderbolt 3 to 2 storage devices connected (I see some people are saying this may be causing some of these Panics). Zero issues.

I am not quite sure why as of yet, but my BootROM is still:

Boot ROM Version: MP61.0120.B00

It never seemed to update during 10.14.4 or any of the 10.14.5.x. So if your BootROM version is different from mine, you may not be as lucky with rolling back to 10.14.3.

Side note - anyone else have their comments deleted? This thread was 4 pages long just a few days ago.......

Well, after read about this discussion, I brought my Mac Pro late 2013 to local apple for roll back my IOS, they don't have or they don't want to provide 10.14.3 but be able to put a fresh High Sierra 10.13.6, went home set up and running until now, it's been half day gone, no more panic no more reboot. I can pretty much confirm it's issue of 10.14.4.

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

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

I'm simply speculating based on volume. There's a ton of these trashcans in the wild but respectively there's not many of us complaining about an issue thats more than apparent. Makes me question whether there's an additional factor thats keeping Apple from getting flooded.

With respect to memory, I'm unfortunately not well enough versed to know whether timings could cause wait states that might adversely cascade into the unresponsive processor panic. Without knowing what Apple is doing under the hood ... it's all speculation at this point. I'm just questioning why isn't there more uproar, especially considering the cost of the machine.

Sadly, I'm having to mothball mine until this gets resolved.

Just upgraded to 10:14.6 so far no crashes and i was getting them every 10 min with 64gb ram previously however when i removed 1 16gb ram chip and reduced it to 32gbGB or even 48GB the kernel panics were far less occurring but still persisted. Lets see how this plays out and will update everyone later this week
