MacBook Pro 2012 13” SSD upgrade issue

Hi guys,

I want to upgrade my MacBook Pro 13” Mid 2012 by replacing the original HDD with a Crucial BX500 SSD.

Using recovery mode and a USB to SATA cable I initialized my SSD (APFS) externally. I then installed Mac OS X Mojave and continued like a new device.

With Migration Assistant I moved all the things back to SSD and I selected it like the starting disk I want to use.

I shut down the Mac and I replace the HDD with SSD but when I try to turn it on the disk is unreadable. In recovery mode the disk is back to MBR (Master Boot Record) and it’s empty. What’s the problem? How can I fix it?

Update (07/02/2019)

This is my cable, I don’t read any other number

The apn code is 821-1480A

That's the manufacturer number so I am told. That number seems to be associated with the bad SATA II cable that looks right (but isn't) in most cases.

It's so cheap to replace I'd just do it and put the matter to bed so you know it isn't the cable.

Did you change and protect the cable? Some of the 2012’s use the known bad 2011 cable, which are NOT RATED for SATA III. The problem is the board is SATA III capable, but not the cable. You end up with these errors since the cable isn’t able to do it, but the machine insists on using SATA III due to the board. In other cases, you have a Fixed SATA III drive and the legacy modes aren't there so you get errors AND forced SATA III speeds which cause the problem to be worse.

According to @danj when I was told to check mine as I had to change it since I own a 2011. The part number is APN: 923-0104.

You will need to replace the hard drive cable with a later production one that can handle SATA III drives, and pad the machine (and cable) to prevent it from failing on you again as easily. Refer to these photos:

@kiwi0024 your comment keeps getting lost to iRobot but I seen it in moderation and know what you said.

The 2011 has a 100% replacement requirement. The 2012 does need to be inspected and you need to see if the cable is the SATA III ready one or a early revision that predates the production run fix Apple added to the 2012 machines. I suspect you have a SATA II run machine since you have these issues. What matters is the APN and appearance of the part you're buying - not the cable number but I've found the 2049-A is likely to be a good one to use as it tends to match up with the revised cable.

Is it not bad that this cable is SATA II and not III? However I don’t where to find the apn number..

Yes. The drives run at full SATA III speed but error out when you put a load on the drive.

Hi @kiwi0024 - did you resolve your SSD upgrade?

I appreciate this is a long time ago for you, but I have got the same issue with exactly the same model MacBook pro (mid 2012) and SSD (crucial bx500) upgrade that I am attempting.

I has all been mildly frustrating and following @nick's advice above I replaced the cable (also 821-1480-A). Unfortunately I have tried out the new cable from ifixit (821-1480-A) and it doesn't appear to be the problem. As mentioned in the comments, I was rather hoping to receive the 821-2049-A, but there wasn't an option to select when purchasing. I have reached out to iFixit to see if they are able to swap it out for me.

Anyway, just wondering what the results were here and hoping to get any further advice on this issue. Never thought upgrading to an SSD would have been this challenging! But it seems as if this combination is quite a niche condition.

Thanks,

Justin

@justintheport - This cable is quite fragile! Often when someone has replaced the cable and is still suffering I find the mis-handling of the cable is the issue. The ribbon cable is a sandwich of a thin copper foil which can be damaged when bending the cable which you need to do. I often find people will create a hard crease thinking that doing so makes sense where the cable needs to bend around a corner. Sadly, that is not the case! Instead we want a nice radius turn. I use an old BIC pen ink straw as a forming break as I don't want the bend to be tighter than what I can form with the straw. Basically, any sharp bend damages (fatigues) the foil wires so high data rate transfers are not distorted which is what you are facing.

So you'll need to replace it again and make sure you don't damage it. Here is the needed cable: MacBook Pro 13" Unibody (Mid 2012) Hard Drive Cable

Hi guys, Denis from Bologna, Italy is writing this post.

I'm trying to upgrade this MBPRO 13 mid 2012 for a customer of mine and I have the same issue. I'm pretty sure that the problem is not the cable. I tested the new SSD Drive with Mojave with an other Macbook and it works fine through an USB 3.0 Adapter for SATA Drives that I use regularly to check the disks. In this case the MBPRO 13 mid 2012 doesn't see the new ssd with Mojave both in one way (mounting the disk inside the Mac) and the other (using the USB 3.0 Adapter for SATA drives). Obviously if a use the old standard disk it works correctly and this MBPRO boots in both ways, and the same happens with other SSD with different versions of MacOS previous than Mojave.

I did this job several times with this kind of MBPRO13 and always with good results but I don't remember specifically the year of construction of these MBPRO13 I worked with. It's the first time that something so strange it happens in my personal experience with MBPRO13

Apple over the years upgraded the SATA drive from SATA II (3.0 Gbps) to SATA III (6.0 Gbps) so it’s likely you didn’t encounter issues with the older SATA II systems with a SATA II drive. Even still sliding in a SATA III drive into a SATA II system can also create odd behavior! So make sure you’ve put in the correct drive as you can drive your self nuts!

Let’s use a mind model to help explain things… You are driving in the large wheat fields of Umbra of course your Ferrari race car will get through! But maybe a Peugeot Wagoner would be better! This is the conflict of using the right cable and one that’s not damaged.

So while your external case works without a problem you haven’t proved or disproved the cable issue! Now someone who has fixed many of these I can tell you everyone I get in with issues like this always get fixed by replacing the cable and making sure not to damage it in the process.

@danj And to flip that example: If I was after fast 1/4 mile speeds, I'd use the Ferarri because they are essentially street legal race cars. You will not get fast 1/4 mile times in a Wagoner.

@nick - Just not in the dirt roads doting the wheat fields, a good paved road is what you need! 😊
