Believe t-shirts at WWDC were not enough.
Thus the workstation market joins OS X Server.
They made a shirt. It was fun.
The most notable feature was that there were mac-specific graphics cards, and you could also run PC graphics cards (without a nice boot screen). They had a 1.4kw power supply I believe, and there was extra pcie power for higher-end graphics cards. You could upgrade the memory, add up to 6 or more sata hard disks (2 in dvd slot). You could run windows, dual booting if you wanted and apple supported the drivers.
The 2013 was kind of a joke. small and quiet, but expansion was minimal.
2019 looked beefy, but the expansion was more like a cash register for apple, not really democratic. There were 3rd party sata hard disk solutions,
the 2023 model was basically a joke. I think maybe the pcie slots were ok for nvme cards, not a lot else (unless apple made it).
nowadays an apple computer is more like an iphone - apple would prefer if everything was welded shut.
It had many hardware upgrades over the years - upgraded CPUs, 128GB RAM, 4TB NVME storage, a modern AMD GPU, USB3/c, thunderbolt, etc
The only reason it got replaced is because it became too much of a PITA to keep modern OSX running on it (via OCLP)
Replaced with an M4 Max Mac Studio, which is a nice and faster machine but with no ability to upgrade anything and much worse hardware resale value on M-series I'll have to replace it in 2-3 years
Well, not exactly. Apple’s desktop Macs actually all have modular SSD storage, and third parties sell upgrade kits. And it’s not like Thunderbolt is a slouch as far as expandability.
I can see why the Mac Pro is gone. Yeah, it has PCIe slots…that I don’t really think anyone is using. It’s not like you can drop an RTX 5090 in there.
The latest Mac Pro didn’t have upgradable memory so it wasn’t much different than a Mac Studio with a bunch of empty space inside.
The Mac Studio is very obviously a better buy for someone looking for a system like that. It’s just hard to imagine who the Mac Pro is for at its pricing and size.
I think what happened is that the Studio totally cannibalized Mac Pro sales.
"Modular" does not mean that it's serviceable, repairable or upgradable. Apple's refusal to adopt basic M.2 spec is a pretty glaring example of that.
I get the ideological angle, but in practical terms that's not a barrier: https://www.aliexpress.us/w/wholesale-apple-ssd-adapter.html...
You can argue that it's different for the sake of being different, but
A) I personally don't always hold that monopoly is a good thing, even if we agree m.2 is fairly decent it doesn't make it universally the best.
B) I'd make the argument that Apple is competing very well with performance and reliability..
C) IIRC there are some hardware guarantees that the new filesystem needs to be aware of (for wear levelling and error-correction) and those would be obfuscated by a controller that thinks its smarter than the CPU and OS.
if we're talking about Intel era Macs then that proprietary connector predates M.2 entirely and is actually even thinner and smaller (which is pretty important when the primary use-cases is thin-and-lights); though I suppose that the adapter fits is a sign that it would have been possible to use a larger connector...
We should demand better of our computer-manufacturing overlords.
> It’s not like you can drop an RTX 5090 in there.
Why not? Oh, right, because Apple won't let you. Sad.
It was exactly as modular as the Mac mini and Mac Studio.
The only difference is that it had some PCIe slots that basically had no use since you couldn’t throw a GPU in there, and because thunderbolt 5 exists.
Yeah, sure, there were some niche PCIe things that two people probably used. Hence the discontinuation.
I am an ex-Mac user, I own a Framework. Don’t worry, you’re preaching to the choir.

I'm not sure if this is what the parent meant by "a real modern PC," but it would certainly be 1) faster and 2) vastly cheaper than the Mac. So at minimum, your assertion that it'd be slower is wrong.
Depending on your configuration, you could likely also match the overall power consumption of the Mac as well, though yes, it is easily possible to exceed it. But the most likely way you'd exceed it is with a high-end GPU, which would vastly outperform the (fixed, non-upgradeable) GPU in the Mac.
P.S. Does anyone know how well Studio Displays now work on Linux? The best I could get it to work was on Ubuntu, where it basically worked out of the fresh install. X11 KDE on Fedora was a close second. Couldn't get it working on Wayland whatsoever.
The money's all in selling phones to teen girls now, and taking their mafia cut of app store sales.
G5 was the thing. And companies were buying G5 and other macs like that all the time, because you were able to actually extend it with video cards and some special equipment.
But now we have M chips. You don't need video for M chips. You kinda do, but truthfully, it's cheaper to buy a beefier Mac than to install a video card.
Pro was a great thing for designers and video editors, those freaks who need to color-calibrate monitors. And right now even mini works just fine for that.
And as for extensions - gone are the days of PCIe. Audio cards and other specialized equipment works and lives just fine on USB-C and Thunderbolt.
I remember how many months I've spent trying to make Creative Labs Sound Blaster to work on my 486 computer. At that time you had to have a card to extend your system. Right now I'm using Scarlett 2i2 from Focusrite. It works over USB-C with my iPhone, iPad and Mac. DJIs mics work just as good.
Damn, you can buy Oscilloscope that works over USB-C or network.
It's not the Mac's or Apple's fault. We are actually live in the age where systems are quite independent and do not require direct installations.
My GPU, NVMe drives and motherboard might disagree.
…so what do you actually need PCIe for?
Thunderbolt is also too slow for higher-end networks. A single port is already insufficient for 100-gigabit speeds.
Apple recently added support for InfiniBand over Thunderbolt. And now almost all decent Mac Studio configurations have sold out. Those two may be connected.
Thunderbolt is external PCIe.
This is a wild and very wrong take.
Just about every single consumer computer shipped today uses PCIe. If you were referring to only only the physical PCIe slots, that's wrong too: the vast majority of desktop computers, servers, and workstations shipped in 2025 had physical PCIe slots (the only ones that didn't were Macs and certain mini-PCs).
The 2023 Mac Pro was dead on arrival because Apple doesn't let you use PCIe GPUs in their systems.
I don't understand how this is a response to anything I said.
I don't see it disappearing, at most we'll get PCIe 6/7/etc.
This word does not appear to be in any way relevant. You do not have to buy a MacBook Neo, but approximately everyone else in the low-end laptop market will.
If you think it is a bad product, go buy some Acer stock.
And Apple is effectively committing to supporting 8GB computers with their OS upgrades for years to come.
• Multiple hard drive bays for easy swapping of disks, with a side panel that the user could open and close
• Expandable RAM
• Lots of ports, including audio
• The tower took up no desktop space
• It was relatively affordable, starting at $2500. Many software developers had one. (The 2019 and later Mac Pros were insanely expensive, starting at $6000.)
The Mac Studio is affordable, but it lacks those other features. It has more ports than other Macs but fewer in number and kind than the old Mac Pro, because the Mac Studio is a pointlessly small desktop instead of floor tower.
I was talking about the form factor of the machine.
I knew it was all over when third party companies had to develop the necessarily-awkward rack mount kits for those contraptions. If Apple actually cared about or understood their pro customers, they would have built a first party solution for their needs. Like sell an actual rack-mount computer again—the horror!
Instead, an editing suite got what looked like my bathroom wastebasket.
Then they said they couldn't upgrade the components because of heat. Everyone knows that wasn't true.
By the time Apple said they had issues with it in 2017, AMD were offering 14nm GCN4 and 5 graphics (Polaris and Vega) compared to the 28nm GCN1 graphics in the FirePro range. Intel had moved from Ivy Bridge to Skylake for Xeons. And if they wanted to be really bold (doubtful, as the move to ARM was coming) then the 1st gen Epyc was on the market too.
Moore's Law didn't stop applying for 6 years. They had options and chose to abandon their flagship product (and most loyal customers) instead.
If you take one apart you'll see why, it's not the case that you could have ever swapped around the components to make it dual-CPU instead; it really was "dual GPU or bust".
Somewhat ironically, in todays ML ecosystem, that architecture would probably do great. Though I doubt it could possibly do better than what the M-series is doing by itself using unified memory.
https://i.ebayimg.com/images/g/RQIAAOSwxKFoTHe3/s-l1200.jpg
For what is essentially a dead-end technology, I'm somewhat doubtful people would have bought it (since the second GPU is going to be idle and add to the cost massively).
the CPU being upgraded would have been much easier though I think.
At which point I'll decide whether to replace my Mac Pro with a Mac Studio or a Linux workstation; honestly, I'm about 60/40 leaning towards Linux at this point, in which case I'd also buy a lower-end Mac, probably a MacBook Air.
The M5 generation Pro and Max chips have moved to a chiplet based architecture, with all the CPU cores on one chiplet, and all the GPU cores on another.
https://www.wikipedia.org/wiki/Apple_M5
So what will the M5 Ultra look like?
If you integrate two CPU chiplets and two GPU chiplets, you're looking at 36 CPU cores, 80 GPU cores, and 1228 GB/s of memory bandwidth.
I bought a GPU maybe a decade ago for this, and it's not worth the hassle (for me at least), but a nice out-of-the box solution, I would pay for.
If they had done more with NUMA in the M series maybe you could have a Mac Pro with M5 Ultras that can take a number of M5 "daughter cards" that do something useful.
It really could have been a bigger market for them than even the iPhone.
Intel should have shipped their GPUs with much more VRAM from day one. If they had done this, they'd have carved out a massive niche and much more market share, and it would have been trivially simple to do.
AMD should have improved their tools and software, etc.
Apple should have done as you say.
Google had nigh on a decade to boost TPU production, and they're still somehow behind the curve.
Such a lack of vision. And thus Nvidia is, now quite durably, the most valuable company in the world. Imagine telling that to a time traveler from 2018.
Apple is counting on something else: model shrink. Every one is now looking at "how do we make these smaller".
At some point a beefy Mac Studio and the "right sized" model is going to be what people want. Apple dumped a 4 pack of them in the hands of a lot of tech influencers a few months back and they were fairly interesting (expensive tho).
But for some reason Apple thought the sound recording engineer or the video editor market was more important... like, WTF dude? Have some vision at least!
As for not having a Pro or otherwise expandable system? It’s shit. They make several variations of their chips, and I don’t think it would hurt them to make an SoP for a socket, put a giant cooling system in it, and give it 10 or 12 PCIe slots. As for what would go in those slots? Make this beast rack mountable and people would toss better network cards, sound/video output or capture, storage controllers, and all kinds of other things in there. A key here would be to not charge so much just because they can. Make the price reasonable.
The Xserve has been dead for 15 years now, and it was never tremendously amazing (though it was nice kit).
Apple apparently has some sort of "in-house" xserve-like thing they don't sell; but turning that into a product would likely be more useful than a Mac Pro, unless they add NUMA or some other way of allowing an M5 to access racks and racks of DIMMs.

Apple's new "Pro" definition seems more like "Prosumer".
bigyabai•5h ago
None of the Apple Silicon hardware can seemingly justify this form factor, though. The memory isn't serviceable, PCIe devices aren't really supported, the PSU doesn't need much space, and the cooling can be handled with mobile-tier hardware. Apple's migration path is "my way or the highway" for Mac Pro owners.
redwall_hp•4h ago
One of those with an M* Ultra, and some sort of Thunderbolt storage expansion would probably cover most of the Pro's use cases. And Apple probably doesn't want to deal with anything more exotic than those.
al_borland•4h ago
It seemed like the guts of the Mac Pro were essentially shoved inside of a box and stuck in the corner of the tower. It would seem like they could decouple it and sell a box that pro users could load cards into (like other companies do for eGPUs). It wouldn’t feel like a very Apple-like setup, but it would function and allow Apple to focus where they want to focus without simply leaving those users behind.
I suppose the other option would be to dispense with the smoke and mirrors and let people slot a Mac Studio right into the Mac Pro tower, so it could be upgraded independently of the tower.
The alternative is people leave the platform or end up with a bunch of Thunderbolt spaghetti. Neither of which seem ideal.
testing22321•3h ago
I always hoped we’d get a consumer version of what they have internally - 10 or 20 or more Apple Silicon chips for 1000 cores or so.
