    Hi all,

    Really need some help please.

    My MBP 14,1 (non Touch Bar) has since installing 10.13.4 (up from 10.13.3) been constantly inflicted with kernel panics. I managed to capture the below crash log.

    I have reseted SMC and NVRAM but no change. The crash happens at any time rendering the machine unusable.

    I have attempted to reinstall MacOS but the problem persists even from the initial user set up screens.

    Safe mode seems to work, but that is no solution to this ongoing problem.

    I have no time machine backup, as I bought the machine in December and have only really begun to use it in the past couple of weeks.In fact, I was about to sell it a few weeks ago and it was wiped clean and was still in 'vanilla' mode when the problem popped up on Monday. No 3rd party drivers were ever installed.

    Any ideas, please?

    A few things come to mind, and which solution you follow is going to depend upon what resources you have available, and some other specifics about your situation.

    If when you reinstalled, you did it from the restore partition, that is different from restoring by formatting the SSD and doing a completely new, fresh install. Whenever I reinstall macOS (or OS X) I do so (because usually I am reinstalling in prepartion for selling it, I want to completely wipe EVERYTHING,) I use a thumb-drive prepared with the latest version of the OS downloaded from the Mac App Store. UNDERSTAND: if you reinstall macOS or OS X, (unless something's changed in the last few years,) it does NOT completely wipe the drive, only the parts with the OS on it, leaving alone things like your USER directory/directories, and possibly parts of either the system libraries, (/Library) or the Applications (/Applications) where the problem COULD be located, though of course I don't know the specifics of your situation.

    If you can access your user files that you'd like to save from single user mode, and have some sufficiently capacious, clean, reliable external drive, I'd first manually copy just EVERYTHING (or everything you want to save if you're obliged to be selective) to that external drive before proceeding. Use it as a life raft for your data, for anything you want to save and can. If you can't, then... well, um...

    I'm sorry you don't have backups, but if you transferred files from a previous machine, perhaps via an external drive you may simply have to repeat the process after doing a complete wipe and re-installation. If you have a lot of new files downloaded, more recently created, or modified in the last few months since starting to use your new machine, or that only exist on THAT machine... and the MBP won't run for more than a couple minutes, my next suggestion involves the following question: How close are you to your nearest accessible Apple Store?

    If you take it there, as there's something (you may have heard of) called "Target Disk Mode," which basically turns your machine (if I understand how it works) into a giant thumb-drive, accessible from another machine plugged into it. This is handy if you have files you want to get off and it doesn't pretty much work at all, since I believe target disk mode uses only the most rudimentary parts of the OS, and can only barely be said to be running at all.

    If you don't have another Mac capable of reaching into your MacBook's SSD and rescuing your files via target disk mode, and you couldn't retrieve them using single-user, the guys at your nearest Apple Store should hopefully be able to assist you in doing that. I'd bring an external device, (USB 3 or C or whatever you have on your computer,) clean and freshly formatted and capacious enough to receive the entire contents of your user directories, with you to the Apple Store, (if that's an option for you,) and see if they can't pull all the files off and stick them on your external device for you. Unless you can retrieve them from elsewhere, i.e., where they came from such that they ended up on your MBP in the first place, in which case you'll just have to do that, if you follow this procedure.

    Basically, (and this is what I'd do if I didn't want to go to the Apple Store or could not, etc.) what you'll need to do is get a thumb drive between 8 and 32 GB in formatted capacity, (I think it has to be a thumb, an external USB HDD I've heard won't work with this, but I that be completely wrong, don't quote me,) and using a working Mac, go into the App Store, and download a fresh copy of macOS, then install (not copy, INSTALL) it to the thumb drive. (Simply copying the APP won't give you a BOOTABLE thumb drive, which is basically what you'll need to have for this.) The procedure can be found readily enough searching the interwebs with your prefered search engine, for "make high sierra install media" and follow the directions you find at whichever of the websites that come up look the most promising. (Not sure if MacRumors will let me post an external link to someone else's website, so I won't, but it's easy enough to find the directions.) They'll most likely tell you to download it, open a terminal window, and then type (or copy and paste) something like, "sudo /Applications/Install\ macOS\ High\ --vol..." etc.

    If you have no other Mac and can't get to an Apple Store, (or some other computer repair shop you might have to pay money for,) you might be able to do this in single user, which if you're not having kernel panics, and can get it to come up in single user, open the app store, (don't recall if it's possible to open app store in single user,) and make this thumb drive in single user, that'd be good because it means you're self-sufficient, when it comes to rescuing your computer, which is handy because next time you'll know how to do it.

    ONCE the install media is created, and you've backed up any data you have and can, that's the time for the next step, which is to pop that USB stick in the MBP's USB port, reboot and select to boot from the THUMB drive. (Bear in mind, with this procedure, you'll DEFINITELY lose any data and files on your machine, so only do this if there is literally no other option, OR if you know you have already safely rescued all your files that you want to keep from the metaphorical flaming wreckage. Rather than just installing, (which I think will still preserve your files but it SOUNDS like, maybe NOT resolve your trouble, though you can try it that way first if you like--it's less invasive. As a last resort, having saved all the files to an external drive and double-check that they arrived on the external "raft" device okay, and haven't been corrupted or lost, I'd proceed to open the "disk utility" in the menu of the restore OS/Install macOS High Sierra menu, and order it to format the main system disc on the MBP. (This WILL obliterate all your data, and you'll have to start all over from backups, so please make sure you have them.) When that's done, exit the disk utility, THEN reinstall macOS HS, and see if that fixes the problem. If it's STILL doing it, you're most likely then looking at some sort of hardware problem, and you need to take it to Apple. Even without Apple Care, if it's only a few months old with a demonstrable, frequently-occurring problem that is demonstrably NOT because of something you did*, they should fix it for you, or replace it with a new one.

    *NOTE: it is just possible that the problem is the result of malware of some kind. Though Apple won't OFFICIALLY endorse a third-party product they don't sell, I have been told by SEVERAL Apple Tech Support employees that they recommend (without Apple officially sanctioning the recommendation,) a product called "MalwareBytes," which I would use (and have used,) to scan files and make sure none are infected with mal, spy, or or other bad "ware" that could be causing problems with the machine. BEAR IN MIND, the power and stability and security that UNIX systems, (including OS X since 10.3, I think,) and macOS, (underneath all the pretty, it's technically UNIX, or would be if they were allowed to call it that... after the big AT&T v. EVERYONE lawsuit, they couldn't technically call it UNIX per se...) only serve you to make your computer running some version or flavor of UNIX, (including OS X/macOS) robust and secure if you ADMINISTER it PROPERLY, which means not installing just any random piece of software you find floating around, that hasn't been digitally signed by either Apple themselves, or one of their identified developers, whom you're PROBABLY safe assuming are basically reputable. The fact that it's so secure really doesn't help you if you go into settings and switch the security settings to "just run whatever I try to run without regard to digital signatures, or any other consideration," because even venerable, old UNIX isn't entirely capable of protecting itself against the computer's own user.

    Hopefully this was all more informative than confusing, and that some of this somehow helped. I have recently been through something similar, though my problem wasn't "no backups," mine was, ironically, TOO MANY. I had to try to figure out, of tens or hundreds of thousands of files, each of which I had about a half-dozen copies of here, there, and everywhere, which was the most recent version, and the one I wanted to keep, and it took days to straighten out. Once I DID though, I formatted a nice, big, heavy-duty external USB 3 drive, formatted it, and designated it my Time Machine Backup, because... I'd love to NEVER have to do that again. Best of luck!

    ONE OTHER THING (follow up to previous rambling post...) if you're going to do this at home yourself, and you manage to rescue your files, I would safely eject, then physically unplug the device with your rescued files on it, BEFORE attempting a reinstall from a thumb drive, just to ensure that THAT drive with the backup files rescued from the MBP's internal SSD, does NOT get accidentally overwritten. Just to be sure.

    Honolulu HI
    There's a few reports on the web from people having this kernel panic. However all five report the exception 0xd, vs. the 0x6 that you have. If it can run in safe mode under the same circumstances it crashes in regular mode, it's likely a software issue but I wouldn't totally rule out a hardware problem.

    If you download and run EtreCheck, it will identify software that runs without the user starting it (and which will not run in safe mode). You can identify possible problem candidates or if you need help, post the results.

    Three of the possible software candidates that other people identified with this kernel panic was Dropbox, Rack and a possible malware program.

    Hello to you both. Apologies I haven't been able to answer... I really do appreciate the replies.

    I might have to run EtreCheck again in safe mode as it would crash in normal mode (due to the kernel panics), however, the one time I did get it to run in the early stages in safe mode, didn't really give me any better indication as I recall.

    I have taken on your advice, halluxsinister, and booked in an appointment with a Genius for Saturday next week.

    It seems this is a bit of a rare one.
