NOTE: If you have panic reports, you could post them. Sometimes Panic reports can be useful

Kernel Panic reports: Finder -> Go -> Go to Folder -> /Library/Logs/DiagnosticReports

<http://support.apple.com/en-us/HT200553>

The panic report should have "panic" in the file name.

One update: I worked with no problem with the mac for many days. Then I tried to install again the ethernet/thunderbolt NHI driver.

And booom: the device started switching off again.

This happened severl times.

Then I removed again the driver and the unit started working properly again.

So, I can say that this is repeatable.

I tried installing the latest sw release (last week) hoping that it would have helped, giving me back my ethernet working. But it didn't.

i have this problem to , my iMac 5k {6months old}has been in to melrose mac and they report no hardware problems whats so ever.

worked for awhile day after then today 10 shut downs in the space of 15 minutes , had to unplug the computer each time.

i have removed all auto strap apps form starting ie dropbox , box and fingers crossed its working so far.

apple please sort out an update to this software problem

I have exactly the same problem, and have done exactly the same things, with exactly the same result... it's still randomly shutting down. The only difference is the length of time in between shutdowns. Sometimes, it'll do it every hour or two; other times, it'll do it every 10-15 minutes. This morning, it was doing it almost every 5 minutes rendering my MacBook Pro essentially useless. The only thing I've found that works (so far) is to restart in safe mode and just leave it that way. Of course, that disables a lot of stuff and leaves the user experience really jagged, but at least that's nominally useful. But if there isn't an update that fixes this by the time I get back in the US this weekend, I'm going to take it in to the Apple Store and have them help me downgrade it back to Sierra.

Hi...don't know if this will help....I noticed the problem on my High Sierra Mac Pro only after I put Firefox on my dock and installed Endnote X8x so I figured something about one or both of those were the likely culprits. I got rid of Firefox on my dock and my problem fixed.

Well...so far so good.

High Sierra bugs are still present even with the new 10.13.3 update. I accidentally upgraded to High Sierra last month and it's been nothing but problems. Previously was on El Capitan with no issues.

Main Issues:

• Sometimes iMac will not wake up from sleep/power saving mode. I have to pull the power cord and restart manually. I'm forced to either power down constantly or leave iMac running with screen saver on. Otherwise it's 50/50 I have to pull the cord to restart it.

• Occasionally freezes, lags and/or shuts down iMac all together while running Adobe programs (Photoshop esp.)

• Terminal won't recognize my password thus I can't make a USB boot drive to downgrade (smh)

I've tried everything from attempting to downgrade back to El Capitan (can't, see above on terminal), re-installing Adobe software, re-installing High Sierra, reset PRAM, safe mode, fixing permission errors, and creating new user/admin acct, etc. I even spoke to an Apple rep via phone and he basically suggested everything I already did. Nothing works. This update is ruining my editing bay. No happy Apple. Was going to upgrade to a new iMac but now I'm hesitant if the "latest and greatest" OS is so flawed.

iMac Late 2012

2.9 GHz Intel Core i5

10.13.3

Hello Lyy17, if I make an "ls", this is what I get:

ls /System/Library/Extensions/AppleThunderbolt*

/System/Library/Extensions/AppleThunderboltDPAdapters.kext:

Contents

/System/Library/Extensions/AppleThunderboltEDMService.kext:

Contents

/System/Library/Extensions/AppleThunderboltIP.kext:

Contents

/System/Library/Extensions/AppleThunderboltNHI.kext.BAK:

Contents

/System/Library/Extensions/AppleThunderboltPCIAdapters.kext:

Contents

/System/Library/Extensions/AppleThunderboltUTDM.kext:

Contents

So, I think you should find the file/folder only with the .BAK extension.

Otherwise, probably, you did not disable it correctly.

ciao

Same problem with me for both 10.13.2 and the new 10.13.3 updates. Forces me to restore back to my last good 10.13.1 backup and at that point, EVERYTHING works perfectly. I'm not able to upgrade at all at this point. I also took iMac to Genius bar. Hmmmmm... Recommendation was to reinstall new OS and reload all of my APPS from day 1 manually. Yeah, right. Everything has always run perfectly even including 10.13.1 yet now "I" have a problem and also there as so many with posts on these forums having problems. We need HELP, not excuses... Really hacked at this point.

If its any help I had the same problem with my mac mini since 2011. I bought some software - caffeine - which resolved the issue. Just upgraded to an Imac and I'm having the same issue even with the caffeine app running.

I wouldn't hold your hopes for apple to do anything since to my knowledge this problem has for me existed since 2011 ***

I updated to 10.13.2 the day it came out, but it has had no effect. Yesterday while on the phone with Apple, it shut down four different times, each 10-15 minutes apart. I did everything they said and also reinstalled High Sierra and it shut down twice more today. Does anyone know if there's a relatively pain-free way of downgrading back to Sierra? It was very stable for me. I'd really love to be able to do it without erasing and restoring everything.

I have the same problem too, and I am getting crazy. I spent money to buy another battery...indeed the technician did not know what else to do and he bought for me a battery and replaced it. Actually I was not in agreement with him, and, in fact, waste my money: the problem is still persistent. I cannot work without my mac and I am really upset.

Dear jayymacc YOU SOLVED MY PROBLEM!

That's incredible. I spent 200 dollars to change the battery, it was completely useless.

Thanks to your suggestion to disable the ethernet, I worked perfectly during all this night, and succeeded on doing the backup (before I always was on mode "Preparing backup", completely frozen also after having removed the BackupInProgress file).

NOW I DON'T HAVE THE ETHERNET WORKING (actually I never use it), but can move back to work!!!

Please Apple, solve this bug and give me back my ethernet.

----->>> Anybody needs a used but perfectly working battery with 200 cycles? ;-) #$@$!#$@$%@!!!!
