Hey folks,

A while ago I installed an SSD into my friends Macbook Pro 13" and installed Mac OS for him.
Now suddenly, while he was watching Netflix, the system froze and couldnt bootup again. (Folder with question mark).
I tried mounting, verifying and repairing but Disk Utility did not show any errors. Partition map seems to be fine.
I also put the SSD into my own Macbook Pro 15" (2011) but the problem persists. At least this is giving me a sign that my friends Macbook is actually fine.

Upon entering Internet Recovery and using Terminal I found many small, weird looking disks.

Does anyone have a suspicion what might have happened and how to fix this?
Would appreciate any ideas.

Those small disks (disk2 to disk13) are part of Recovery. Type mount to see where they are mounted (if they are mounted). Ignore them.

7C3457EF-0000-11AA-AA11-00306543ECAC is the partition type for Apple_APFS. The Internet Recovery is too old to look at Apple APFS containers so you can can't examine them or fix them here.

What version of macOS did you install on the SSD?
What version of macOS do you have on your 15"? Does your SSD work in his 13"?

19A710A2-B3CA-11E4-B026-10604B889DCF is for Android meta partition (small) and 193D1EA4-B3CA-11E4-B075-10604B889DCF is for Android expand (everything else). Where are these coming from? Your 15" only has room for one drive, so does that mean this is a connected Android phone or something?

Do you have an external disk enclosure you could put the SSD in?

Or use Thunderbolt target disk mode?
Or use FireWire target disk mode?
Or use USB target disk mode?
https://support.apple.com/en-ca/guide/mac-help/mchlp1443/mac

When you boot the Mac (called the Target) into Target Disk Mode with no other Macs connected, then it will show you what connection methods are supported, one or two of FireWire, Thunderbolt, USB (oldest to newest). Then you can use one of the shown connection methods (with appropriate cable/adapter) to connect to a host Mac so that the host Mac can use all the disks of the target Mac as if they were connected directly to the host.

For Thunderbolt target disk mode, the target Mac and host Mac both need to support Thunderbolt (a Thunderbolt 3 to Thunderbolt 2 Adapter can be used if the Thunderbolt connectors are different).

For USB target disk mode, the target Mac must have USB-C ports (also works from Thunderbolt ports). I suppose a USB type C to USB type A cable can be used to connect the target to a host that does not have USB-C ports. Do not connect type-A to type-A.

For FireWire target disk mode, you may need a Thunderbolt to FireWire adapter (either on the host side or the target side or both).

Once the host Mac can see the SSD of the target Mac, then you can run First Aid from Disk Utility.app to check the APFS container and the APFS volumes it contains.

Which SSD did you use in your friend's MBPro?

Can you test that SSD? Launch Disk Utility - choose that SSD from the list - click First Aid.

The SATA cable, used to connect the SSD to the main logic board, can be quite easy to damage.
But, if that SSD also doesn't work in your own MBPro, then the fault is most likely just a failed SSD.
In some cases, you might be able to get a warranty replacement from the manufacturer of that SSD.
But, some companies can make that process less "fun", and take longer than you might think.
So, it might be easier to just go to a different SSD.

WHAT YEAR was the friend's MacBook Pro made?
Would it happen to be a 2012 "unibody" model?
Apple continued to sell this model for a few years after it was first released.

The internal drive ribbon cable is notorious for failure in those.
Cheap and easy to replace.
When the ribbon cable gets flaky, it may appear to the user that the drive is "going wonky" or won't work at all.
Sometimes, a slower platter-based HDD will seem "ok enough", but put an SSD (faster) in there, and ... the cable can't handle it.

"Apple APFS containers so you can examine them or fix them here."
What do you mean? Fix them where?
"19A710A2-B3CA-11E4-B026-10604B889DCF is for Android meta partition (small) and 193D1EA4-B3CA-11E4-B075-10604B889DCF is for Android expand (everything else). Where are these coming from? Your 15" only has room for one drive, so does that mean this is a connected Android phone or something?"
Sry about that, it was a SanDisk microSD Adapter with a card inserted on my 15". Not very professional of me :confused:

Thanks for all the information!

Unfortunately I dont have any way to test Target Disk Mode right now.

Selecting the drive, verify disk results in no errors.
But Repair fails. "disk0s2", unknown file system.

I have fixed the ribbon cable before, took me 2 orders from amazon but the second cable worked.
In this case though the SSD should work in my 15" macbook, Im pretty certain that the cable works in mine but ill swap the SSD back to the 13" and put my SSD back into my 15" to see if everything still works.

@joevt

The reason why disk utility cant recognize the file system is because its too old right?

Can I somehow update that or create a modern recovery partition that can recognize APFS to check the disk?

Get some cables to do target disk mode.
Or get an SSD enclosure so you can connect the drive to a working Mac.
Or you can install a macOS installer on a thumb drive and use Disk Utility from that.

APFS format drives get challenging to test out, particularly if you have a range of older systems that you might be working with.
If you are creating a macOS bootable installer to try to test the drive, then you want to make sure that the macOS installer version will be, if possible, the same or newer than the version of macOS that you used to format the drive originally.

You said that the drive is a MicroSD card in the SD card slot. Is that correct? I have experimented with that to make another choice for booting some other Macs, and have experienced issues, such as the card randomly not recognized. I always do the same install on two separate cards, so it's a quick step to swap out to the second card. In my experience, the SD card is not a reliable hardware to use for booting macOS. Storing data, OK, but booting the Mac, not so much.

Sorry, I mean't "can't fix them here." You need to boot a newer version Recovery/macOS/Disk Utility to fix it.

He said the second drive /dev/disk1 was a MicroSD card.
The boot drive that he wants to fix is /dev/disk0 which has the APFS partition.

Alright, I used an external hdd usb 2.0 adapter (lol).
I managed to boot the OS this way with the 13" and I ran disk utilities first aid from the OS.

A little complicated to copy the results here because the OS system is set to german language.

The only interesting details I got from the first aid was:
"warning: apfs_num_other_fsobjects (53) is not valid (55)"
"The volume /dev/rdisk1s1 appears to be OK."
"Exit-Code for file system test is 0" (Translated from german)
"The original state will be recovered" (Translated from german)
"Successful".

Ill check if the disk runs internally now.

Running the First Aid again gives the exact same results.

Running internally, I am still getting the Folder with Question mark.

Why would the OS be bootable with the adapter, but not internally..?

I ran Internet Recovery with the disk connected externally with the usb adapter.

Disk Utility Shows the disk but its not mounted and its called "disk12s2".
Verify/Repair doesnt show any errors.

Too bad I dont have a big enough USB stick right now.

I have 2 questions --
What version of macOS are you booting to run Disk Utility?

What version of MacOS do you think should be installed on the SSD (the drive that only shows the disk identifier disk12s2 ?

Oh, yeah, just checked.. its OSX Utilities Version 1.0 (53)...

The MacOS version on the drive is High Sierra 10.13.6

Do you think I might be able repair the disk with a higher Utility version?
Is it possible to make a usb stick for this without the whole OS on it? I can only find a 4GB USB stick right now.

By the way, the disk utility version on the OS is 17.0.3 (1646)

I was asking for the macOS system, not the Utilities version.
You can easily find out that version by opening "Reinstall OS X"
The installer will open to a setup screen, showing you the system version. Actually just the version of the system installer, but will also be the recovery system system that you are booted from.
(Quit the installer to return to the menu, of course, unless you want to continue with that... :cool: )
The reason I ask, is that if your recovery system is older, it may not recognize a newer format, such as an APFS drive.

Yes, Mountain Lion will not be able to do anything with the drive that has High Sierra or higher, that will usually be formatted APFS.
Best choice is to boot to an OS X installer, such as a USB flash drive, or other external drive, which is set up with a High Sierra (or newer version) bootable system installer. Using Disk Utility from that newer system version will give you the best chance of repairing the file system.
But, I would suggest that you simply try the macOS reinstall. If you don't see the internal drive THEN, your only next choice with that drive is to try erasing the drive. And, you would want to select the device, not the volume, so you have the best chance of a good result. If you continue to get errors, and it just won't erase - replace that drive, it has failed.

You're leaving a lot of info out of your explanation.
What disk did you put in the USB 2.0 adapter?
What disk is not in the USB 2.0 adapter?
What disk did you boot?
What OS did you boot?

I ran Internet Recovery with the disk connected externally with the usb adapter.

Disk Utility Shows the disk but its not mounted and its called "disk12s2".
Verify/Repair doesnt show any errors.

Too bad I dont have a big enough USB stick right now.
I'm not sure how Internet Recovery works.
Does Internet Recovery work when no disk is attached?
Or does Internet Recovery run from the disk? I suppose if something is coming from the Internet then it needs to be saved to disk so it can be run?
I understand that disks that have macOS installed to them all get installed a Recovery HD partition or a Recovery volume, but that Recovery partition/volume doesn't require the internet to use it.

What version of macOS is on the 13 Inch?
What version of macOS is on the 15 Inch?

You don't have a USB stick, but you do have the SSD from the MacBook Pro 15 Inch. Shrink the existing partition on that SSD to add a new partition and install a new macOS to it. Then use it to check the SSD of the 13 Inch.

Internet Recovery is the feature of your Mac system that will boot your Mac from Apple's remote servers.
It only requires an internet connection.
It does not require any local or internal drive to be attached, and does not transfer any files to a local drive, unless you choose to do so.
It boots to that remote system, providing a means to completely erase an internal drive (if that is necessary), including any recovery partitions, then install a system on that drive. Internet Recovery originally would provide the same system that shipped with that Mac, so could be quite old (Lion, Mountain Lion, etc.) although now Internet recovery might offer more recent versions. I tested that out about a month ago, using a 2012 iMac. Catalina was installed on that iMac. The installed Recovery system offered to reinstall that Catalina system (as expected). Booting to Internet Recovery offered to download and install Yosemite, although that iMac originally shipped with Mountain Lion.

Seems strange that an Internet provided recovery system would not be the latest that the system supports since it is coming from the internet and not the Recovery partition. I guess this goes back to the days when you had to pay for macOS upgrades? https://www.wired.com/2013/10/apple-ends-paid-oses/

I read the following articles to learn the difference between Recovery and Internet Recovery:

The Apple support article says some Macs will install the latest supported macOS and some will install the version of macOS that came with the Mac.

yeah, i think so, its the same with my 2011 macbook pro 15", i think my friends 13" is from 2011/2012 too.

Guys, thanks so much for your help.
I have lots of stuff to do at the moment, thus my progress fixing this is a little slow.

My financial situation is terrible right now and I have always been a fan of DIY / Fix it yourself,
so I really appreciate everyones input.

I think I can take it from here. I will try to fix this tonight or tomorrow and report back to u guys.
