That’s right.
Late 2013 cause -128 :( Probably old boy needs replacement already
My terminal reads:
Bad predicate (Unable to parse the format string “ ‘eventMessage”): ‘eventMessage
Any ideas?
I got the same message Big Sur 11.7.1.

The previous shutdown causes in the timeframe you selected will appear as a list.
the terminal command does not work in El Capitan. Apparently this works only with Sierra onwards. Any ideas how to get this to work with El Capitan?
Some Macs had 4 Diagnostic LED
I’m getting a
Previous Shutdown Causecode that is not listed in either iFixit or in grgarside blog (Previous shutdown cause: -8). Any ideas on what it might be? Thanks. -

For me it says
kernel: (AppleSMC) Previous shutdown cause: -20
The attached PDF (and the internet) doesn’t seem to have any information about this code. What’s the source of the codes for the PDF? Maybe they have updated listing for shutdown codes.
we also have -20 as a cause and have no idea what it means. did you ever find it out?
I also have -20 code of shut down after macOS 10.15.5 update with MBP 16inches model.
but no information at all….

OS 10.11.6
Hello,
First time posting here but I’m having some issues with a Macbook Air 2020 (Not the M1) having some shutdowns, I have run the terminal command and it’s coming up with Error -67 and I can’t seem to find this one anywhere. Hoping someone has some guidance, Running most up to date Big Sur, (11.1). Clean installed the OS and didn’t transfer a backup over and it seems to be still happening. Also tried an SMC / NVRAM reset, Safe mode, first aid disk. Any advise would be appreciated!
My MacBook air 2015 is unusable now . It keeps shutting down after 5-10 minutes of uses … and the last shut down cause is -128
What should i do now ? any one ????
I have 2014 MacBook Pro 13 and I had the same problem my Mac was shutting down randomly. I looked the logs from the terminal and it stated the problem was power disconnected (shutdown cause 0). So I reset the SMC and unplugged my battery and plug it back to logic board. Also I drained my battery completely and charged it to 100 without distraction and waited 8 more hours on the %100. My problem was solved. Mac never shuts down again and my Mac is working faster. Maybe this information will be helpful to somebody.
cloud gaming, -128 is not the error you want to see as it refers to a problem with the logic board
cheers
Hello , what would be this command but for a M1 rubbing lates Ventura version ?
in my case it is -128 which is same to -112. can you please tell me the solution
I had a -128 code. I reset the PRAM, NVRAM by shutting down the computer. When starting the computer I held down cmd + option + P + R until the Mac restarts a second time. This seems to have fixed my issue. Hope it helps!

The terminal responded:log: warning: The log archive contains partial or missing metadata
log: cannot use --last when archive metadata is missing
Any advice anyone?
