Kernel Panic after upgrading to 10.14.4

I started having this problem on 10.14.5 yesterday. After reading through all the options and trying various things, I believe that one or more of the following helped me (sorry I couldn't be more scientific as I didn't have time to figure out precisely which one):

1. Reset the SMC How to reset the System Management Controller (SMC) on your Mac - Apple Support
2. Physically cleaned the Mac Pro by removing the case and using compressed air on it.
3. Reformatted one of my external backup drives.

I also tried turning off SecuritySpy (just upgraded it) and turning off VMWare Fusion. I even pointed a fan at it.

Once this problem started, the machine only stayed up for a few hours; I'm going on 18 hours without a problem and with decent load and disk I/O.

Based on my reading of the thread, I tend to think there is/was a thermal issue (my office did get hot yesterday), so resetting the SMC and cleaning out the machine may have helped get the fans going at the right time and keeping the temperature within reasonable limits.

I hope this helps someone.

The error correction hardware is used very aggressively at Startup. ANY error, correctible or not cause the associated slots to be declared "empty" and they will not be used by MacOS. These modules are BAD. But on subsequent startups, they will be tested again and may then be used by the system. This does not change the fact that such modules are BAD.

I can also confirm these findings -

• 10.14.3: both apple and third-party ssd do not crash
• 10.14.4 & 10.14.5: both apple and third-party do crash

Updated my Apple engineering case with this information as well.

Regarding the comment of 10.14.6 beta only crashing once - one time is too many, sadly. If it crashes once, chances are it will happen again.

Back in late March, my Mac Mini completely died. Luckily i had a time machine back up and restored a new Mac Pro (Late 2013) from that. Pretty much since I got the new computer, it has had panic shutdowns at night or when i leave for 40 mins during the day from work. It does not happen every night but it happens every few days. I'm pretty sure the computer has always been running on 10.14.4 and 10.14.5. After all of the "basic" troubleshooting, Apple says to bring it in but based on what i'm reading, it will be a giant waste of time.

All hardware is brand new from Apple

• Processor: 2.7 GHz 12-Core Intel Xeon E5
• Memory: 64 GB 1866 Mhz DDR3
• FirePro D700 6 GB
• 1 TB Flash Storage

I can provide panic reports if anyone else thinks it would be helpful. Even though mine does not crash as much as others, I wanted to provide the info that i have all factory hardware from Apple within the last 3 months and mine still has panic crashes also.

I have a few different ones from the 6 panic reports i saved over the last 5 weeks.

• Panic(CPU 0, time 122953388614781): NMIPI for unresponsive processor: cross-call timeout
• Panic(CPU 0, time 195958478922161): NMIPI for spinlock acquisition timeout, spinlock: 
• Panic(CPU 0, time 58634348287864): NMIPI for unresponsive processor: cross-call timeout
• panic(cpu 0 caller 0xffffff7f88dfefe5): pmLock: waited too long, held by 3@0xffffff80058dd929

To check firmware versions, use:

 menu > About this Mac > (system report) ...

The opening page there has the "Boot ROM version"

--------

Panics like yours in CPU Power Management routine is where many Hardware problems show themselves, but is not an actual indication of power problems.

Unresponsive Processor is a complex multi-Processor and interrupt problem, sometimes including the GPU(s) as Processors.

So I installed my OEM Apple SSD and installed the Catalina beta to it. I then reinstalled my OWC SSD and booted back into Mojave 10.4.5 (release version). The Boot ROM is now 132.0.0.0.0. I'll update the thread in a week or so about whether I get any more kernel panics.

I have just updated the final version of the 10.14.6 which had just been released. BOOT ROM updated to 132.0.0.0.0. I upgraded from the original 10.14.

So far I've had no problems, 30 mins going. Knock on wood it will be just fine. I will post update if something comes up.

If you have multiple Mac Pros, and move disks around, are you certain you have installed the correct firmware on each and every one of your Mac Pros?

Two firmware updates surrounding Mojave have enabled APFS Volume format and NVME drives.

Same issue here. Kernel panic as soon as I installed 10.14.4. Had to restore a TimeMachine backup.

I am having the exact same issue. NMIPI for Unresponsive Processor on my 2013 MacPro. It was completely stable on 10.14.3 - installed 10.14.4 and immediately the machine started suddenly rebooting from kernel panics. I rebuilt fresh Mojave with 10.14.3 and I was back to stable. Upgraded again to 10.14.4 (no 3rd party software) and I immediately went back to constant cpu panics and immediate reboots. I have tested this with both OWC and Transcend 420GB - both drives are stable on .3 but then suffer from the same CPU panic after the .4 OS update. Please help. I can obviously revert back to 10.14.3 - but can then no longer update my Mac??

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.

Has anyone found if upgrading to 10.14.5 (18F118d), MacPro6,1, Boot ROM ver. 130.0.0.0.0 has fixed the issues? That's what I am running, but I haven't rebooted since upgrading to 10.14.5 (18F118d)... and right now my Mac Pro is running perfectly. I also did find that if I rebooted, and left the Mac Pro sitting at the login screen, for perhaps 10 min., and then logged in, then all would be fine...
