Latest Sierra update crashed my MPB

Hi,

This is the second time i get in trouble after updating my OSX!

I make clean installs now and then so my MBP is very clean and i don't have much on it, basically use it for surfing nowadays.

Any how yesterday when i updated from App Store it rebooted my computer and all i saw what this sign:

https://dl.dropboxusercontent.com/u/33591942/OSX%20Sierra%20crash/2017-02-15%202 2.10.31.jpg

After more digging i got to see these errors in the background:

https://dl.dropboxusercontent.com/u/33591942/OSX%20Sierra%20crash/2017-02-15%202 2.11.05.jpg

ERROR!!! prelinked kernel corrupted

ERROR!!! Load prelinked kernel with status 0x800000000000001b

Error loading kernel cache (0x1b)

What is this all about!?!? i tried to repair using disk utility and macOS Recovery where it did not allow me to continue and install again.

Got some other error:

https://dl.dropboxusercontent.com/u/33591942/OSX%20Sierra%20crash/2017-02-15%202 2.45.08.jpg

It was only when i used my USB stick i had created with previous OSX version and run the disk utility and repair that i could finally get back into the computer. No idea what the **** it was all about but honestly i'm scared doing more OSX updated now. They seem to mess up to many times. Last time i also could not get into the OSX, don't remember how i fixed that but it was also scary.

Did anyone else encounter this problem?

Also should i do some check to see if something is broken? if so how do i do that? Don't want to reboot later and get into the same mess.

Personally i get a feeling that the quality has been worse with every software Apple releases these days. From iOS updates to OSX updates. Maybe i'm wrong but thats just my guts feeling.

macOS Sierra (10.12.3)

It is very likely that a hardware fault is the cause of your problems; specifically, that Mac's hard disk drive. Disk Utility is of limited use for such diagnoses, leaving only anecdotal methods. The problems you describe strongly support that hypothesis. For example, you wrote that you attempted to use Disk Utility to "repair" it, and attempting to reinstall macOS did not allow you to continue. You also wrote that you experienced similar problems in the past. Lastly, its age is reason to question the hard disk drive's integrity.

Since Sierra introduced a completely new logging system, I do not know of a reliable way to diagnose potential hard disk problems. Disk Utility will not suffice. Until I come across a disk in a state of failure yet operational enough to test I can't provide a means of extracting any applicable log entries that could definitively show those failures. A definitive conclusion could be drawn by installing Sierra on an external hard disk drive, booting from it, and determining if the symptoms are alleviated while running Sierra from that startup disk. To do that read How to set up and use an external Mac startup disk - Apple Support. If the external hard disk installation of Sierra works properly while the internal one does not, that is all the justification you need to replace the internal drive.

Hard disk drives are wear items that should be replaced when they become unreliable. Fortunately they are inexpensive and easy to replace on a MPB. Unfortunately, it has become abundantly clear that Apple is no longer interested in using them in any of their products, and that support for them is likely to diminish if it has not already disappeared altogether.

ehmmm ok how do you come to that conclusion? Just because its 7 years old does not automatically mean its HW problem. Where did you draw the line. Seriously i want to get help from someone who knows more about the errors i provided and solution to them.

And if it was HW problem it would not magically solve itself when i run firstaid from an old start disk.

So no i dont believe its HW problem sorry.

ps. I ran the Hw test without finding problem also.

FWIW, I didn't come to a conclusion, I said it was possible and you might want to have it looked at. As far as FirstAid, it's not an exhaustive test.

Seriously i want to get help from someone who knows more about the errors i provided and solution to them

I'll let you wait for someone else then.

Good Luck.

@John Galt

Thanks for the detailed explanation. I should have said that i use a Samsung 950 Pro SSD. So that is one reason i did not consider the wear and tear but sure it can be the SSD as well. They do break.

Just not sure else i can test it properly and determine if its in good condition.

Any good program to recommend?

@dialabrain:

I appreciate your help but being a computer nerd myself i like to know more about people analysis. I should have said the SSD i made a few year back but please dont take it in a wrong way. I do appreciate the help but i like to understand why people come to a conclusion.

Using an external startup disk, one that is known to be operational, will be instructive. If it works, swap it with the internal one. If the problem follows the SSD, you found the culprit.

I do not know of any utility that would be particularly useful to diagnose a problem with it. I have seen such things report failures with perfectly good drives, as well declare broken ones perfectly OK.

Samsung SSDs do not enjoy a particularly good reputation among Mac users. If it requires a firmware update, which is possible, you need a Windows PC (as far as I know).

FWIW, I came to the "conclusion" because I believed you when you said you had made clean installs and were still having a problem. You stated what errors you were getting and that often points to a hardware issue as John explained. Simple as that.

I think we misunderstood each other.

I have never had any problem after install or anything. I encounter this specific crash once and another crash that was different from this. Both times (maybe there was one more but not sure) it happened right after making appstore update to the OSX.

Like now i dont see the problem so changing the drive dont do anything really. I could boot from external drive and do HD or rather SSD testing if i knew any good software. Will google for it.

Still the errors are a mystery. I read about them of other forums but no one explain exactly what cause it and why.

So which is it?

As you are aware Samsung SSDs do not enjoy a very good reputation among Mac users. You will not advance troubleshooting until you take steps to isolate it as the cause of your Mac's poor performance.

Hi,

Samsung SSD 840 PRO is correct. I mixed it with my PC which has the 950 Pro.

Still wonder about my first question which is what the errors actually mean and how to fix them. I have worked as a developer and these messages seem to me to be a software error:

ERROR!!! prelinked kernel corrupted

ERROR!!! Load prelinked kernel with status 0x800000000000001b

Error loading kernel cache (0x1b)

What causes a "prelinked kernel corrupted" ?

Also my MBP has worked without a issue since i somehow got it working. I'm on the other hand worried that it will pop up next time Apple does a update and like to understand why these error occur and how to fix them.

If you google it there are many people with the same problem but there is no confirmation that any of the ideas work for sure or what causes the problem:

That is entirely likely and your concerns are justified. That is the risk you take when modifying a Mac's hardware, and is the reason Apple does not approve of such modifications.

You will not be able to fix the problem since Apple retains sole control over macOS and the hardware on which it is designed to be installed. They are utterly disinterested in anything else. They wouldn't even dignify a complaint such as yours with a response.

The only SSDs that I have used and can personally recommend are manufactured by OWC / MacSales, specifically their Mercury Extreme Pro SSDs. Failures are almost unheard of, whereas Samsung's failures are common. If an OWC SSD requires a firmware update to cope with future macOS releases, OWC provides it. Other manufacturers are just as unlikely to care about that as Apple.

Sorry as a engineer i can just laugh at your comment. Are you seriously claiming Apple HW is failsafe? All HW fail sooner or later. I have used this SSD for some years now so if it was incompatible i would not see it after some years. Also a simple google shows how wrong you are about the Mercury SSD:

https://www.google.se/search?q=failure+Mercury+Extreme+Pro&ie=utf-8&oe=utf-8&cli ent=firefox-b-ab&gfe_rd=cr&ei=Qz63WIPaKIKA8Qeo05agDw

Samsung SSD is among the best (did allot of research before i selected this and read lots of reviews at the time).

Any way i still wait for someone with knowledge about my errors and hopefully some explanation that is based on facts.
