Prices via the self service repair program:

512GB ~$450
1TB ~$550
2TB ~$850
4TB ~$1300
8TB ~$2200

Add tax and get 88 bucks back for sending the old modules back in.

The Mac Studio repair manual (manual ID: CWQBNX) is available, and says that the serial number ending in 0 or 1 for the nand module indicates which slot it is supposed to go into.

If anyone is willing to sell their 512GB module, I'd like to try downgrading and would be interested in making a deal (that's less awful than the $450 price... dang).
For the self-service repair program, do they allow you to purchase any size, or do they restrict you to the size that originally came with your machine?

You have to enter the machine's serial number. In Mac Studio case, it won't show you dual card options if yours is a base with just one card.

Right. But if you have a smaller dual-card set, will it allow you to upgrade to a larger dual-card set, or does Apple only allow exact replacements?

Also, what's the minimum size that gets you dual cards?

Unfortunately, they restrict to only the size that came with your machine.

They only sell the exact replacement.

See attached screen captures, one for a 8TB Mac Studio, one for a 4TB Mac Studio.
(price is without shipping and taxes, and eventual refund for the old parts)

Though you can do it, the prices are pretty insane. Prefer the route of getting an external drive. Most of why I have 10TB SSD on my PC is for games, don't need to worry about that on the Mac. Although I don't really *need* to keep everything installed anymore with 1.2Gbit/1.2Gbit unlimited fiber. Also, I have 30TB free on a NAS I can just move things and move them back when I'm actively using it.

I recommended people buy the absolute biggest SSD they could afford, and was told I was crazy for suggesting that. With macOS and applications, I think I am at at least 50%, and I have the 2TB.
Probably because the Mac isn't my daily driver and I have a 10Gbit NAS with 30TB free but I'm using 20% of the internal (512GB) and 5% external thunderbolt storage (2TB).
It is, however, much cheaper to get a 8TB NVMe drive at only $1200.
The 7.68TB enterprise drive in the PC (u.2 with an adapter) was under $600.

At least Amazon sells the 4TB Mac Pro 2023 SSD upgrade for less than the 2TB option but still very expensive at €986.68 (compared to a 4TB Samsung 990 Pro priced at ~€337).

That should work in the M2 Max and M2 Ultra Mac Studios, right?

What implication does this have for upgrading the slotted SSD modules on the Mac Studio?:

They aren't paired in any way, except you are only able to order what your computer originally came when it comes to storage through the Self Service Repair shop.

Apparently the NAND modules used in the M2 Max and M2 Ultra Mac Studio and Mac Pro (2023) are the same, so you can just buy them directly from Apple or 3rd party retailers (2TB, 4TB and 8TB available).

OK, I took another look, and I can see that parts pairing as a term of art is very specific--it's about allowing a part that will work in one Apple device to work in all devices of the same model, regardless of the serial no.

I was thinking of pairing in a different sense--namely the restriction that prevents 3rd parties from making after-market slotted SSD modules: Currently, the only modules that will work are those that have the circuitry that enables the part to pair with the machine.

This is not part pairing based on machine serial no., it's part pairing based on being an Apple OEM part. That's why the only way the modders can make this work is to solder larger NAND chips into Apple OEM modules.

Given that the point of this legislation was to allow 3rd party parts to work, it seems narrowly restricting it to those defeated by serial no. specificity makes it too narrow--you're still restricted to using Apple OEM parts only (or, in the case of the modders, modifying Apple OEM parts).

Hi, thanks for your info.
I want to confirm this.
If I have a base Mac Studio M2 Max 512GB SSD, can I purchase the Apple 4TB or 8TB SSD Upgrade Kit for Mac Pro, from Apple and it will work fine in the M2 MAX Mac Studio?
Can you tell me what else I need to do to get it working?
Do you have a price and timeframe for releasing 4TB and 8TB SSD for M2 MAC Studio?
Thanks


This one.

Hi,
unfortunately no, it won't physically fit.
SSD upgrades kit for the Mac Pro M2 are a few milimeters longuer than those for the Mac Studio and the card would hit the screw spacer.

There is enough room in the Mac Studio case for the MacPro M2 SSD cards to fit and you could grind or unsolder the screw spacer but I definitely not recommand it.

I don't know if anyone else than us (Polysoft in france) is working on MacStudio upgrades.
We are a bit off schedule on M1 Mac Studio upgrades.
Work is finished (schematics and PCB layout), we lost time because finding a PCB manufacturer meeting requirements was harder than expected and I'm currently verifying a last time our work before sending to manufacturing.
First samples were due to arrive late april but they will only come late may, I'm sorry about that.



As for the M2 we are not yet working on them but if M1 is a success, with acquired experience it should only take 3 months from the time we start working on it to release a prototype.

When you say, the card would hit the spacer. Do you mean the spacer that holds the screw for holding down the card, as highlighted in the attached photo?
Also, after installing the cards, do I need to program the cards, or will they automatically be accepted by the Mac OS?
I'm willing to grind and cut the Mac studio to fit those Mac Pro cards.

Yes, it's that spacer.
For a temporary try, you may not need to grind the spacer, but just ensure it won't create any short on the card.

Be advised that absolutely no one can tell you yet with 100% confidence if the cards for the Mac Pro M.2 will, or will not, work on the Mac Studio M.2.
It should, but there is no 100% confidence.

Hello guys ,
I have Mac Studio M2 512gb
So let me understand,
If I could buy from self-repair with another serial number, one ssd 1tb or single board 2 tb
Will work or not ?after DFU mode etc etc

I haven’t any skill to desoldering so I can only swap the one blade for another bigger…
And with another serial number…

Thanks for your replies and already post here !!
Sorry for a silly question ..
Hope anyone have already tried …

Hello,
There's no silly question.
Yes, it will work.

I don't know since when precisely this has been possible, but you can now order in the SelfService Repair Store any SSD capacity you want..

You are no longer limited to being able to order only the original capacity !
1 TB is $527 and 2TB is $880

Simply enter your current serial number and request an SSD repair, and it seems you'll be able to order any capacity you like.

Once received, follow the Apple repair manual to put in your new SSD.

https://support.apple.com/en-us/104001

Your MacStudio will automatically switch to DFU mode, and you can then restore it using another Mac and AppleConfigurator.

Thanks Sir,
But if I put the serial number of my OG 512gb I can only order an 512
If I put one serial number of the 2tb I can order all the size of ssd

So the question is
Can I put the bigger size ssd if I order with the “wrong” serial number ..??

As I can see if you have 512 you can only buy a 512,,
The other serial number have an original 2tb and can buy from service all sizes exist…

My quest is can buy with this serial number a size I like and will work in my current 512 gb

Oh sorry, I too did checked with a serial number for a 2TB and not with one for a 512 GB MacStudio...
this is insane. Logic boards are identical.

So the question is

Yes you can.
NAND modules are not "paired" with a specific board, as I showed it previously with my upgrades on M1 Mac Studio.

Only the data you are putting into the NANDs are "ciphered" with the unique ID enclosed in each CPU, and thus can not be "decoded" on another Mac Studio.
But you can anytime put any properly configured 2TB card in any Mac Studio, providing you reformat them / reinstall the OS with AppleConfigurator.

I'll try explain a little bit further :
In factory, "factory blank" NANDs are soldered on the boards.
Then, after that, the NANDs are configured in a sort of RAID configuration :
- 512 GB configs use 4x 128GB nands in 1 card
- 1TB configs use 4x 256 GB nands in 1 card
- 2TB configs use 4x 512GB nands in 1 card
- 4TB configs use 8x 512 GB nands in 2 cards (which order is to be respected)
- 8 TB configs use 8x 1TB nands in 2 cards (which order is to be respected)



You can order on Apple Self-service repair program a single 2TB module (661-34239) from any serial number, put it in another M2 MacStudio with any serial number (just respect the single 2TB module configuraiton = put the single card in the 00 slot), and restore with Apple Configurator and it will work, 100% garantee.

You can do the same with ordering a kit of 2x 2TB modules module (661-34240) from any serial number, put it in another M2 MacStudio with any serial number (just respect the dual 2TB module configuration = card 00 in slot 00 and card 01 in slot 01), and restore with Apple Configurator and it will work, 100% garantee.

etc.

What will never work in trying to put 2x "single 2TB modules" (661-34239) as a 4TB configuration...
because they won't have been programmed for that, and that's why Linus Tech Tips or Luke Miani did failed in their attempt to upgrade M1 Mac Studio.

Yes you both are right...
I'm not sure but this should be due to your both MacStudio M2 purchased before the change of policy from Apple.

Why I'm saying that is that all M1 MacStudio I have purchased (512GB, 4TB and 8TB) are still limited to purchasing the capacity of their original configuration.

Maybe first M2 MacStudio to be sold are still restricted too, as all M1 MacStudio are, and only recently purchased M2 Mac Studio can offer all configurations.
