Went to apply the 10.14.3 Supplemental to my late 2012 Mac Mini i7.

Got about 2/3 through the update, and it repeatedly reboots with "Your computer was restarted because of a problem".

It shows that screen, then the Apple logo and the progress bar, then it shows the same error screen again.

Eventually, it shows the universal "no" symbol, slashed circle.

Anybody else get this?

I've seldom had trouble with updates before.

I can get into recovery mode, and checked the system volume, which was fine. But I cannot check the main filesystem, it won't let me, says it can't unmount it to check.

Thinking I will wait till tomorrow now, as I have a failing hard drive (that I do not use) that I'd like to remove for thermal reasons. (No reason for it to be in there blocking the air flow when I am not going to use it.)

(I have a 1 TB flash, and the old/unused 1TB hard drive from the original Fusion drive. I do have the hard drive formatted and in the system as "backup" but don't actually use it.)

I guess I will try "reinstall OS" after that.

Anything else I should try first? I could swear the progress bar moves a bit on each try.

I hate it that it gives basically no information! Is there a "verbose" update mode?

Fortunately, this is my personal machine that I use just for email/web browsing. I have an iMac Pro next to it for work. But now I am afraid to update the iMac Pro. (Certainly not without a full backup first!)

I know better - I should have an external bootable clone before doing any update. Lazy! It takes WAY to long to create.
[doublepost=1550466314][/doublepost]I knew there was a verbose mode - I've used it before - CMD-V at startup.

Doesn't help me, though, because it just quickly scrolls through and then I get the "...because of a problem" screen, and the scrolled text is gone.

It seems to have the problem very quickly. Just a few pages of quickly-scrolling text then BAM.
[doublepost=1550466445][/doublepost]Very strange, I do not get a startup gong. Just the white apple, the progress bar briefly, and then the "problem" screen.
[doublepost=1550466863][/doublepost]Just needed to unmount the volume to check it in Recovery Disk Utility... Duh!

Stuff you only do when something doesn't work, and in a panic... Not logical that it's even mounted when you boot into Recovery...
[doublepost=1550467643][/doublepost]Disk Utility drive checked out OK. Only thing suspicious was it said "performing deferred repairs", but didn't say WHAT deferred repairs.

Still have same problem. Comes up fine in Recovery. Very quickly comes up with the "problem" screen otherwise.
 
From Recovery select: "Install macOS Mojave" and just let it go. macOS is great in that it can do a major upgrade over itself without losing data.
 
For what it's worth, the 10.14.3 update brought my wife's late 2012 Mac Mini to its knees. She ran it unattended, so I don't know if there was an installation problem. But after the update, there was a 45 second lag between a mouse-click and anything happening on screen. I spent hours troubleshooting.

Safe mode was good, but normal boot was so slow it was impossible to use the machine. Preference panes would error out. I ran recovery mode, installed again, no improvement.

So... Time Machine to the rescue. I used recovery mode to roll her back to 10.14.2 and everything is great again. I haven't decided if we'll try the update again or not. Several hours wasted on a security update, only to have to roll it all back.

Are you referring to the 10.14.2 to 10.14.3 point update or the recent 10.14.3 "supplemental update".

The supplemental update. (Edit: oops, the question was directed to jbarley...)

I previously applied the 10.14.3 update with no trouble.

I am presently reinstalling from Recovery. Having never had to do this before (since 2008 Aluminum Macbook!) not sure what to expect. Is it installing 10.14.3, 10.14.3 with supplemental update, or the original 10.14.0?

Not sure. She moved from 10.14.2 to 10.14.3 according to Time Machine on Feb 15th. Does that help? I wonder if the supplemental update was rolled into that when she updated.

Regardless, after trying to reinstall current version with same result, I rolled her back to the 14th and her Mac is happy again. I'm leaving it for a few days before attempting to update again. Happy wife, happy life. lol.

From my limited experience, a reinstall from recovery will reinstall the version you currently have. Not a prior version. At least that's what I experienced, and since that didn't fix for me, I had to roll back with Time Machine. Hope your reinstall goes smoothly :)
 
So the OS re-install was successful. I have 10.14.3, but can't tell if the Supplemental is installed or not. I guess I will know if I get an update notice again.

Apparently, I have some incompatible kernel extension. I got a BUNCH of popups about blocked kernel extensions, and UNDER them a popup about "Panic Medic Boot" that said a third party kernel extension was preventing this machine from booting" and that all third-party kernel extensions were disabled.

The lack of detailed information from Apple gets more annoying all the time.

The disabling of kernel extensions could/should have been done during the update if there was a problem.

The re-install OS from Recovery could/should have told me WHAT VERSION it was reinstalling.

Install should give meaningful progress messages, not just a progress bar. (I know there is a verbose boot mode, didn't help me in this case because the SCREEN WAS ERASED when the problem was encountered...)

While the lack of communication might make the typical user feel reassured (just the friendly apple logo and progress bar) when things go wrong it is less than helpful.

Even the disabled kernel extension popups are less than useful. They list only the company, not the product or extension!

So, it is likely of:

Parenthesis are my findings or guesses at what the actual software/extension is. Grrrrr.... just knowing the publisher doesn't tell me much!

- Intel Corporation Apps
- Legacy Developer: Jmicron (USB display adapter, can go!)
- Legacy Developer: Silabs (Bluetooth 4.x dongle)
- Wacom (drawing tablet, never use, can go!)

- Oracle America, Inc.

I have additional blocked (but no popup):

- Fumihiko Takayama (Karabiner-Elements)
- MalwareBytes Corporation
- Phillip Jordan
- Avatron Software, Inc. (some iPad display adapter app, can go!)

Some of this is probably detritus I can get rid of. Will have to look them all up. Avatron is some "use your iPad for a second screen" app that I never use, will leave disabled!

Oh, I think jMicron is for a USB display adapter, that can go too!

I will fiddle with this later, with a mouse on the system. (I currently have a spare Unicomp keyboard with an IBM pointing stick plugged in. WAY too annoying for anything more than filling password!)

You may already be aware of this ... but if not, check on the About This Mac and click on the Version 10.14.3 section, as in

Screen Shot 2019-02-18 at 10.06.51 AM.png

If it shows the build as 18D109, then you do have the latest (with the supplemental update)

Thank you! It is indeed the same version you showed above.

I HATE that Apple hides stuff like this. What would be the harm of showing the build without having to click on the version first? It's the whole attitude of "don't worry your pretty little heads over this". It's simplicity gone wild!

Nothing new, it's been a trend with Apple for years. Perhaps The Minimalist has to go! Pretty cases. Yes, pretty cases, and nice packaging. The influence shouldn't extend to software functionality and disclosure of what the heck it is doing during extended operations and what version you have installed.
 
I am SUSPECTING this:

https://github.com/pmj/QemuUSBTablet-OSX

It hasn't been updated in 3 years, and doesn't claim Mojave compatibility.

I GUESS this is the "Philip Jordan" kernel extension.

Edit: I have NO idea why I have this kernel extension. It is I think for making a Wacom tablet look like a mouse (ha! perhaps when using the Wacom mouse?!) but requires running OSX inside a VM. I have NEVER run OSX inside a VM... Needless to say, I think I Don't Need That.

It also says it's a "codeless extension", so hmmmm, it doesn't have any code to crash...

I enabled Oracle, Karabiner, Malware Bytes extensions.

Now I don't know how to get to the list of enabled/disabled extensions until some program asks for permission. *&^%! I want to enable the extension for the Bluetooth dongle. It's for my stereo headphones and Handoff. maybe I'll have to reinstall the driver?
