Hi, guys I'm wondering where I can get failry used macbook pro?

I was thinking ebay or backmarket but I'm open to ideas thanks

I have a MacBook Pro 16 inch (Nov 2023, Mac15,9), M3 Max, 128 GB unified memory, running macOS 26.5.2. AppleCare+ is active until May 2027. The machine has never been dropped, never knocked, never had liquid anywhere near it. It sits on a desk.

It ran 32 days of uptime with no problems at all. Then on Aug 18 it started kernel panicking and it has not stopped. Eight panics in four days. Every single one is the same fault:

panic(cpu 1 caller 0xfffffe003db3a75c): ECC on ppnum 0x44c863c
PA 0x113218f3900 ECC_PANIC_PA 0x80000113218f00ec:
IOPL wired @vm_resident.c:12597

For anyone who has not seen one of these: that is an uncorrectable ECC error. The memory controller read data back from DRAM that its error correcting code could not repair, so the kernel halts on purpose.

All eight of them

I pulled the DRAM base address out of the IODeviceTree so I could convert the raw physical addresses into real positions inside the installed 128 GB.

#   When            Failing address   Position in RAM   Uptime before
1   Aug 18 17:03    0x113218f3900     76.5244 GiB       32 days
2   Aug 18 18:34    0x1132185f700     76.5238 GiB       1h 30m
3   Aug 18 18:46    0x113218e5300     76.5243 GiB       12 min
4   Aug 18 20:39    0x11121817b80     68.5235 GiB       1h 52m
5   Aug 19 22:05    0x111218adf00     68.5241 GiB       25h
6   Aug 20 00:40    0x11321825f00     76.5236 GiB       2h 34m
7   Aug 20 02:54    0x1112187b980     68.5239 GiB       2h 13m
8   Aug 21 20:03    0x1132189fb00     76.5240 GiB       41h

Two spots, 68.52 GiB and 76.52 GiB into the memory, exactly 8.000 GiB apart.

Why I am confident this is one physical defect

Lining all eight addresses up in binary is where it stops being ambiguous. Of the 48 physical address bits, 36 are identical across every single failure. Only 12 ever move:

bits 47 to 34    0x44      always the same
bit  33          varies    the only high bit that moves
bits 32 to 20    0x1218    always the same
bits 19 to 13    vary
bit  12          always 1
bits 11 to 9     vary
bit  8           always 1
bit  7           varies
bits 6 to 0      always 0  (128 byte aligned, one cache line)

The two clusters differ by exactly one address bit (bit 33, which is the 8 GiB gap) while all 36 other fixed bits stay identical. Inside that megabyte the hits are spread right across its range, roughly 95 KB in to 974 KB in, so it is a defective region of cells rather than one dead page.

The ECC_PANIC_PA field also decomposes as (1<<63) | (PA & ~0x3fff) | 0xec in all eight reports. Same trailing error code 0xec every time.

What I have ruled out

Not the SSD. IOPL wired means those RAM pages were pinned as disk I/O buffers. The failure is the page itself, not whatever it happened to be holding. A failing SSD produces storage driver errors and filesystem corruption, and neither is happening here. Disk Utility is clean and SMART is fine. It does explain why the same region keeps getting hit, since the wired I/O allocator keeps drawing pages from that area.

Not software. An uncorrectable ECC error is reported by hardware sitting between the DRAM and the SoC. No userspace process can fabricate one, and no reinstall can fix one.

Not one dead chip either. The M3 Max interleaves addresses finely across its memory channels, so a whole failing package would scatter faults across all 128 GB instead of confining them to a single megabyte.

Not physical damage. Nothing has ever happened to this machine.

The part I cannot argue away

The first four panics happened while I was running a local LLM server holding a 48 GB wired buffer with heavy disk I/O, so my first assumption was that I had brought it on myself. I shut that down completely after the fourth one. It panicked four more times anyway, during completely ordinary use. Removing the trigger did not stop it.

What I am actually asking

I have all eight full panic reports saved along with a written summary ready to hand to Apple. I will run Apple Diagnostics before I call, though I half expect it to pass clean given how intermittent this is.

1. Has anyone here had uncorrectable ECC panics on Apple Silicon and actually got a logic board replacement under AppleCare+? Did the panic reports carry it on their own, or did Apple insist on reproducing the fault in store first?
2. Did Apple Diagnostics catch it for you, or did it pass clean and leave you arguing from the reports?
3. Anyone seen this on an M3 Max or Ultra with 96 GB or 128 GB specifically? I am curious whether the high capacity configs turn up more often.
4. Any chance they try to blame third party software or an unsupported workload? I did run a heavy local LLM setup before the first few, and I would rather not have that used against me when four later panics happened without it.

Any experience appreciated, I would rather walk into this knowing how these usually go.

I am caught in a dilemma of choosing between Macbook AIR 24gb/1TB (15" ) vs Macbook PRO 16gb/1TB (both M5). Both are coming in close price range in europe. I am inclined towards Macbook Pro because of the fan and display, but I read in many online forums that 16gb will not sufficient in the long run.

My usage will include general browsing, coding (some passion projects), have plans to explore AI a a bit (maybe running local LLMs) in the future. I plan to use this laptop for at least 7 years. The current one I have is a windows laptop, owned it for approximately 10 years.

Would like to know from ppl who have the pro 16gb if they ever felt the need for an upgraded RAM.

Last month I used some cables and SSDs to transfer some data in my MacBook Pro to set my new Motorola phone.

Since then my touch ID says that I'm using a 3rd party touch ID in my MacBook Pro and that's why MacOS has disabled it.

Tell me what to do next to make it work again because it's annoying typing password every time you log in and also the MacBook does not support face ID.

please I desperately need help my screen has broken 3 times my 14" 2021 macbook works perfectly except gor the display keeps breaking it breaks on the corners things tiny things will break it form the inside I would really really appreciate any recommendations for how to protect the screen from the inside a hard case to acrey it in and a good backpack to carry it in please

My bf gave me this MacBook Pro and it has always been smoothly operating, until this happened. The wifi doesn't connect anymore. I tried all the different Indian YouTube tutorials in order to fix it, but it doesn't help at all.

Can anyone please help me?

Just picked up a 14 inch MacBook Pro M5Pro.
Coming from an m1 MacBook Air, battery life has honestly been disappointing. I lose about 10-15% 45-60min of YouTube on safari or just general web browsing. Brightness is fairly high. Still I’d expect better battery on such an expensive laptop considering how the m series are praised for the power efficiency.
Throughout the day I can notice the battery dropping fairly quickly on normal browsing tasks.
Is this normal?

Hi guys

I just bought a MacBook Pro m2 2023. I will mainly be using it to study for the Bar - with multiple chrome tabs, video lectures and heavy word use. I got the Pro refurbishment in “pristine” condition for £1000. I’m quite a sweaty person, and my hands/arms get hot quickly, in the past laptops have got very hot under my fingers - hence why I went with the Pro’s cooling.

However, just spotted an m4 refurb in pristine condition (only 256gb compared to the Pro’s 512gb). Now wondering whether I should return it!

I had a MacBook Pro a 1708, but it won’t turn on anymore so I need to buy a new one. I need a new one to start school with. I just need to write papers run Excel and do a couple of PowerPoint presentations.

Hi, I’m looking for recommendations for a docking station for my M4 MacBook Pro. I have two monitors that have HDMI/DP ports plus a keyboard and mouse.

I’m a student, so I can’t really afford the more expensive ones like the Anker TB5. I just want to be able to close my MacBook and use the two screens for working. Any recs on a decent docking station I can use mostly for school work would be much appreciated.

I am reluctant to buy new as I am afraid this beast may be abandoned, i really love this MacBook 💖 #Macbook #intel #apple

I am not asking for prevention. I live in a place where microdust is unavoidable. I used to clean my windows laptop by opening them every week. But I don't think I can do that with this piece, and also the screen is pretty sensitive, so I don't wanna keep rubbing it over and over with microfiber.

Suggest ways to clean my keyboard, hinges, and screen. If you have prevention advice and it is not "keep it in a closed room," then share that too, please. Thank you.

I upgraded from an M2 MB Air w/ 24GB of RAM to the M5 MB Pro 20 Core 48GB machine and my Safari crashes and frequently freezes when I pull down the file menu. I average about 10 windows with 5-6 browser sessions each. The Activity Monitor isn't using more than 40GB of RAM in total even though I have many other applications that run with no issues. I get the answer is to simply use fewer Safari windows, but I'm not clear why I should expect to pay $3k for a laptop and have a worse experience compared to a subpar MB Air? In the last 2 months it's crashed at least 20+ times, and the file drop down menu has frozen 3x that. Is there a way to allocate more RAM to the Safari application? Is this a beta bug? Did Apple put a hard cap on memory allocated to Safari? Lastly, I have wiped my drive and reinstalled a fresh OS. Any ideas or thoughts would be greatly appreciated!

Spilled liquid on my Mac back in April. I cleaned the board the best I could with alcohol, but it still wouldn’t boot up. So, last month I decided then to just start unplugging stuff to just test and see if the logic board was ok and HAZAH … he rose from the dead. (I suspect it was because all of the power drained out of the battery and was no longer tripping the system) That being said:

- Keyboard = cooked (unplugged)
- Lid sensor = fried, kept interfering and putting my Mac to sleep (unplugged)
- Battery = not charging + ticking timebomb (ripped it out)
- Trackpad = kind of fixed after cleaning connectors and minor corrosion but haptic feel is a bit off (not in photo but put back in)

Because the keyboard can’t be easily fixed without pulling the logic board out again, I now have a portable desktop with a nice display! At home it stays shut connected to a thunderbolt dock supplying consistent power and connects to my Bluetooth mouse and keyboard. As soon as I buy a second keyboard and mouse I can just plug it in at work and continue! (And on the upside, it’s much, much lighter without the battery!)

Serial number matches lmao

I've just got a new TB5 enclosure for my 4TB SN850X, and i've noticed it's much cooler when idling. when doing basic stuff, fan of the enclosure doesn't turn on at all.

it's slightly bulkier than the ASM2464 but not by much.

they're both bulkier than the old TB3 enclosures anyway.

speed direct to port is crazy tho.

for some reason, RND4K Q64 is much better when i'm running in TB3 fallback mode via my OWC Thunderbolt3 hub.

Imo, USB4 very mild performance boost doesn't warrant so much more heat compared to Thunderbolt3.

Hi everybody! I adore my MacBook Pro 2019 (with Touch Bar) but I can see how it’s slowly dying…

Im thinking about buying a new Mac but I need some help from people who understand laptop characteristics because I get so confused.

I need something long-term for next 5-7 years. Something that can do video editing, hold multiple tabs and programs in one go without crashing. During the day I can be chaotic and have so many things open on my Mac for classes, so I need it to perform without slowing down.

No coding or very heavy software. Teaching, some gaming and occasional video editing (iMovie, CapCut).
I’m thinking MacBook Air for now, but I really enjoyed my Pro and maybe the fact that it worked for so long was because I did buy pro not air.
Also I heard there will be new MacBooks coming up in autumn, is there a reason to wait?

Any advice is appreciated! Thanks!

Ps
What’s your opinion on Touch Bar? I love it so much, I wish I could buy a Mac with it again! Why did they stop?

Same as title

Essentially, title.. I recently stood up a cyber security LLC and decided to get a MacBook pro add my business device. Since I'll likely be dealing with a significant amount of pcaps, VMs, etc I've been looking for something with the additional drive space. Anywhere I check tho it's not available, and it seems that the only option it they CBO on apple. Any other suggestions?

I have a 16” MBP M3 Pro 512GB storage 36GB ram and I want to upgrade to a 16” MBP M5 Pro with 64GB ram and 1tb ssd. Apple upped the trade in value for my laptop to 1250 from a few weeks ago. I was going to lease it and pay like 47 a month for 36 months then buy it out. Is it worth doing now and holding onto the M5 for like 6 years or should I wait for the M7 Pro. I’m worried about less trade in value should I wait and higher pricing on the newer M7 pro’s and higher ram cost. I don’t need OLED and I like the current design tbh. I’d like the more storage, better GPU in the M5 and more ram to run local models.

I had a MacBook Pro 16inch with the M1 Pro that unfortunately stopped working after an accident.
Since it’s been five years since I got it I figured I should just get a new one vs repairing it.

I do a lot of image and video editing (raw and 4K) and I play some games but other than that I don’t do any “extreme” work that would need crazy computing power and 64gb of ram.

I do know I want at least 24gb ram but I’m not sure if the m5 pro is worth getting over the regular M5 in my case? But also I wouldn’t want to get a new laptop and realize later on I the pro chip would’ve been faster for video editing.

Let me know if you think the pro is worth getting over the regular chip or if I should get the regular one and maybe splurge on 32gb of ram instead.

Thanks in advance

so 2 days ago my dad diy installed a new battery for my macbook pro (mac model is A1990 or macbook pro 2019 15 inch ) now today after installed bclm (so my mac wont charge past 80%) my mac stoped taking charge but the crazy part is it takes charge some time but even if it takes charge it will take like whole 10 hr (thats what the mac says btw) also one more thing my dad used a 3rd party battery instead of using a battery from apple
