Question: CATERR detected! No MCA data found.

My laptop continues to crash randomly. I read a 10 page thread from 2016 here with a similar issue that had no resolve.


Does anyone know how to fix the issue? "CATERR detected! No MCA data found"


Mojave 10.14.2 (18C54)

Are you using an external monitor?


For test purposes, disconnect all USB and Thunderbolt devices and run a while to see if the error recurs.


On the chance it is related to third-party software, we can quickly and within the confines of these forums help you determine if software issues are the problem if you use EtreCheck, available free from the Mac App Store here:


‎EtreCheck on the Mac App Store


It is the development of a long-serving and trusted contributor here expressly for displaying information in these forums to help us help you. It will not reveal any personal or secure information.


Run it, select “Report" from the left-hand pane (scroll down to the bottom of that pane to find) and, when its report displays, click the "Share Report" icon from EtreCheck’s toolbar and then "Copy report” from the resulting dropdown.



Please DO NOT highlight the text in the report before using Etrecheck’s “Copy report” command—that will garble the formatting and make the report slower and harder to evaluate. NOTE: Recent changes to the forum software require you use the "additional text" icon (see example below) to embed the report into a post:


Paste the report into the resulting “Add Text” window.


Also see this excellent user tip on posting text reports like EtreCheck. It is better illustrated than mine.

Thank you for the through answer.

Yes I am using an external monitor. The crash only happens about twice a week. So it will be a bit painful to not use my mac on a doc for a week or two in order to fully test. If this is the problem, my next question would be: Now what? Can I not use an external monitor with my Mac any longer?

I will run EtreCheck and post back here.

Thanks for the follow-up. I saw another external monitor thread (not about this error) that made me think to ask another question:

When using the external monitor, is your MacBook Pro running on battery or wall power?


Can I not use an external monitor with my Mac any longer?


Too early to make that leap. It doesn't seem to be a universal problem. Let's see if EtreCheck shows any software conflicts. Those can usually be fixed at your desk.


I'll also ask some of my fellow volunteers to look into your thread.

Local rule of thumb: machine checks are hardware or very low-level software or firmware.


They’re best tossed more directly at the folks from Apple.


These errors? I’d expect a low-level bug in macOS is a possibility here, but I’d also wonder about a low-level bug in the display.


Usual suggestions for these cases: try a different path out to the display such as switching from DisplayPort to HDMI, try an entirely different vendor’s monitor or a very different model, try a different cable, check that the monitor firmware is current and upgrade that to current if not—LG TVs have had incompatibilities with Mac HDMI that were fixed by LG firmware upgrades—and then escalate the machine check crashes directly to the folks at Apple Support.


FWIW, if you want to post crashes here, use the highlighted button to open a text input window that's larger...

For most folks, contact Apple Support or whoever is providing hardware service.


But if any of y'all want a technical intro to the Intel CATERR machine check? That'll lead you to some far more detailed Intel technical documentation. That documentation might then allow the cause for the machine check to be determined, and for a particular Intel x86 processor.
