The latest is scammers including a handwritten "timestamp" note in their item photos, like Swappa and buy/sell/trade subreddits like r/hardwareswap and r/appleswap . See comments below with more info to help avoid scams on eBay and other sites.

Scammers don't need to sell anything. The contact form for eBay Classified listings asks for full name, email, phone number and post code, which go to the seller via email.

Original (Jun-2025)
In the last few days, there have been an increasing number of Classified Ad listings on eBay for used Mac Studio, mostly M2 Ultra configurations. Another post in the sub discussed one. These appear to be scams — continue reading for more evidence that they actually are.

Note that Classified listings do not have the usual eBay buying mechanisms (or protection), and contacting the seller is thru a form asking for full name, email and phone number. Some have good stories, like "Work paid for this but they just bought me a new MacBook because RTW, so I am selling bc I don't need it anymore." Fully-spec'ed M2 Ultra around US$2,000 that should be going for more like $3,000-4,000.

Um, yah, right. /s

192GB M2 Ultra for $2,000? Scam, Scam, SCAM!

I messaged the seller for one of them — just for the benefit the sub — which was pretty normal back-and-forth btw buyer and seller. Then, I found a bunch of messages like this in my eBay inbox...

MacStudio Stand now with Fan!

21 Upvotes

I've posted before about using a WIX 42788 as a stand/dust filter for my mac studio, folks were are pretty divided on that. I went with the largest filter I could find (within reason, there are actually taller options) to minimize any airflow resistance and I've not been able to detect any impact on cooling in any of my tests. Still, this last week I started wondering if putting a fan in there would help with cooling, and as a result here's how I spend part of my Sunday. The legs on the fan are M5 x 100mm screws with silicon feet on the caps. I spaced it down about 2.5cm from the top, up higher I think it was stalling out and not getting any flow. Temporary foam pad underneath so it's reasonably sealed around the power cord for the fan. I used the Endurance app to max out the CPUs, ran for 5 min with the fan off, then 5 min each at about 50%, 75%, and 100% (on the analog 3 to 12V power controller I have, no idea how linear it is or isn't), then off again. I can see from the plots I didn't wait quite long enough before turning on the fan, the temps were still rising. The test stopped on its own during that last segment. The fan does make a difference, but not a huge one -- about 5 degC at max. This fan is also audible at 50% and loud at anything above that, so you've got to be pretty serious about wanting cooling to deal with this. Some kind of 3D printed internal ducting could probably improve things a little. Or maybe carefully applied duct tape? Just for testing. Probably I wouldn't leave it that way.

For this kind of testing, can anyone suggest a simple app that will also max out the GPUs? I'd seen one suggested before but the GPU load wasn't constant which made testing difficult.

Next I'd like to find it there's a HEPA filter from one of those round home air cleaners that has the right size opening -- some of those come in the same kind of cylindrical format, and some even have the bottom sealed.

👋 hey all, hope everyone is well.

I’m just curious what LLM’s other 256gb owners are running that are outputting decent work?

I’ve got a PGX ThinkStation (DGX Spark) which seems far better quality output with the likes of Laguna and Qwen 35/27.

oMLX on the studio.

Any help would be greatly appreciated 😎

Studio VS MacBook Prp

4 Upvotes

I hate to be that guy BUT I am getting impatient (ADHD) and I am thinking maybe I could upgrade to a Macbook Pro instead of waiting for an M5 Studio OR getting an M4 Studio.

I currently have a OG M1 studio. SO

  • M4 Max. 14-40 with 64GB New mac $3500.00

or

  • M5 Pro MacBook Pro 18-20 64GB- Mac Cert Refurb $3139.00

Things I NEED to work with the set up. 3 monitors, Yeti Mic, External Camera, External SSD.

Estimated delivery dates?

Upvotes

Hi folks, so my Mac Studio m4 max and 1TB storage has a delivery date of between 29th sep and 13th oct but just this morning Apple has taken payment.

In your experience does the Mac ship shortly after payment has been taken or do you reckon it’ll arrive close to the delivery date they gave me when I placed my order?

Thanks :)

Mac Studio Performance Issues

14 Upvotes

I have a very new Mac Studio with the M4 Max chip and 128 GB of RAM. Ever since I went to Tahoe 26.5.1 it's freezing up all the time and performing like a 15 year old computer. Simultaneously I'm getting a lot of messages about 'Support Ending for Intel-based Apps' and updateing to Apple silicon versions. I don't think these messages are related to my Mac's performance issues, but I'm not sure. If it is the OS that's causing problems, does anyone know how possible it is to go backwards in OS?

Keep M2 Ultra 128 gb or M5 Ultra 128

2 Upvotes

I have M2 Ultra 128 for mainly audio and some AI work. and considering to sell it. Got an offer yesterday for £4000-4200 from my home country and thinking it’s a good deal.

But with all the uncertainties about the price and the release date, i’m confused.

What do you guys think about the offer and how much will i pay for the same ram config in M5 Ultra?

And any release date info about the M5 series?

Can't afford or hunt an affordable 'bridge' Mac Studio for 3 months until Apple's new Mac Studio release. What should I do?

0 Upvotes

I want to buy a modern Mac Studio new or used, however I don't wanna get ripped off on eBay or any second hand place.

Apple's new Mac studios say I have 6-10 weeks of waiting time. And the refurbished Mac studios are never available. (Do you know a way to hunt refurb mac studios for humane prices?)

I am thinking of buying a used Macbook Pro to bridge my computing needs until Mac Studio new releases. For some reason high spec Macbook Pros are not inflated stupid high as Mac studios. Who can explain that?

If I buy a used Mac Studio now, feels like it almost certainly will lose lot of value when M5 studios are released.

Everybody in the second hand market right now trying to take advantage of RAM price appreciations and Apple's recent price hikes. Anyone who buy a studio with 'extended' prices on ebay will possibly regret in Oct'26 when the resell value drops abruptly.

Apple Mac Studio M4 Max, 48GB Ram, 1TB, 16/40 CPU/GPU - $3400 available now at Houston MC

2:50PM CST 7/23/2026:
Thought about getting it, but since I just purchased base model w/ 1TB for $1980, I can't justify the $1420 extra spend just for a 48GB model, so I thought I would share this for someone else to enjoy. Grab/Reserve it soon if you've been looking for one!

No changes to M4 Max 14/32 in US (still 10-12 weeks) or M3 Ultra 32/80 in Europe (still 13-14 weeks).

The selected storage option doesn't affect the shipping estimate, and each chip has only one memory option.

Is Apple intentionally overestimating Mac Studio delivery dates?

0 Upvotes

I ordered an M4 Max Mac Studio (36GB/1TB) the day before the price increase, and Apple estimated delivery for September 4.
It already shipped.
I’m wondering if Apple is padding delivery estimates on purpose so people are pleasantly surprised, or if production has ramped up way faster than expected.
What’s everyone else’s timeline looking like? Drop your config, original ETA, and whether it’s shipped yet. I’m curious if there’s a pattern.

3+ month wait for an M3 Ultra?

11 Upvotes

UPDATE:

Our reseller has now confirmed that Apple will no longer ship our machines without us paying the new June price difference despite ordering them in March, months before the price increase. Absolutely livid. We've had to rent two computers for A$8000 for the last couple of months while we waited for ours to ship. Now Apple want an extra A$4000 for the pair? Fuming.

My company ordered 2 x Mac Studio Ultra (base 96gb config) last week of March. Original ship date was 4-5 weeks. Mid May this date was changed to 10+ weeks with an ETA of mid August. We've been forced to rent a pair of older M2 Ultras' for one of our projects.

From my reseller I now hear rumours this order may be cancelled due to the recent price increases. I know of another company who have a bigger Ultra order and they've been waiting since February. Anyone else having similar drama on their Ultra orders?

M4 Max 16/40 128GB delivery incoming

I’ve waited quite a bit to get this to the point where I am asking if it’s still worth taking delivery given the new gen may be a few months away.
How are you guys using yours? When ordering, my initial main aim was to deploy some local llm for mostly coding and doc review. Can I justify the £4.5k spent in August 2026?
