After a bit of help!! I have a 2022 Mac Studio M1 Max. It has started not booting up. When I press the power button the white light flashes on for about a second,the fans kick in and then it shuts down. Very occasionally it will load all the way through and when it does the studio runs fine and works perfectly. I have taken it to an Apple Genius Bar and they got it to boot and factory reset it but when I got it home it loaded up once and is now doing g the same thing. Has anyone else come up against this and how did you fix it please?
Got a tip for us?

Same computer and it has never happened to me.
Do you have anything, other than a monitor, keyboard and mouse, connected to the Mac?

I just can’t work it out and gutted because it’s such a great machine. Nothing connected apart for monitor. Using an Apple mouse and wireless keyboard.
What about if you startup in Recovery; press and hold power button.
It will let you see and select any bootable volumes, and do things like run Disk Utilities to see if there are any issues with your boot drive.

When you say the Apple store folks "factory reset it" are you saying that they deleted everything that you had put on it and you had to start from scratch?
it doesn’t even get to the recovery stage. Even if I press and hold the power button it gets to the point of playing the chime and then shuts down again half way through the start up chime.
Yeah they deleted everything and had to start from scratch. They fresh installed Mac OS and said they had got it to boot to the welcome page no problems. I got it home and the first time I turned it on it worked perfect. Set it up as a new Mac and shut it down. Came to it the next day to turn it on and was doing the same thing by not starting up.
Then something is very wrong with your mac.
I think you should go to an authorized dealer/repair shop, and avoid shop assistants that knows little about this sort of thing.
When you say "set it up as a new Mac" did that include using Migration Assistant to transfer apps, data and settings from a previous Mac or backup?
No nothing backed up from backups, Time Machine or a previous Mac. It was a fresh install and logging in as a new user having to download apps and so on.
There is definitely something not right with it mate. Just can’t work out if it’s hardware or software really.
The store folks may have run Apple Diagnostics but that's what I'd do next…if you haven't already.

Apple Diagnostics, formerly known as Apple Hardware Test, can check your Mac for hardware issues.
Excellent thanks for that I will give it a try and see if it will boot that far.The store folks may have run Apple Diagnostics but that's what I'd do next…if you haven't already.

I have same problem with my Mac Studio ultra max, and try my best to solve problem, I try many things 2 times installed OS from Apple service centre and and try to remove all peripheral devices, it’s on sometimes and then again next day not booting up only light blink one time, feeling stuck …. Did you get solutions bro, it will be appreciated, regards
I have the same problem. Mac Studio M1 Max 32/1Tb. My Mac turns off after chime sound. Sometimes it starts as usually without problems, sometimes I have to disconnect it from the power socket and wait for 30 seconds. Today I did a clean install of Sonoma, connected to another power socket.
I did multiple hardware tests....no errors....Can it be an OS and firmware problem? I don't remember any issues with Monterey....but I can't go back due a software requirements.

How did you do that? I am gonna downgrade this weekend: I am having crashing and slowing issue. Took senior advisor support and performed reinstall but didn’t solve my issue. Now was trying to open recovery menu. But after one hour try in tired. I can’t bring the boot menu. Holding and pressing the power button but nothing showing in display.
God. Did you get your files back? If so, I how?
I would also love to know to cause of this issue. 1.5 year old Mac Studio M2 Ultra, from one day to the next, the power LED flashes once and nothing happens. After removing the power cord etc. for a while, it boots and works fine. Putting it to sleep is okay, too - and no error when running HW diagnostics...
My feeling is that there is a firmware problem or similar, because it all started after an update of macOS Sonoma.
However, if the PSU has died, there is a realtively inexpensive way to get this part from Apple and replace it yourself - the only question is: It this issue caused by the PSU board or not. Phew.

I have a new MacStudio M4 and have had the problem not booting several times since i bought it in April 2025. Held the power button, light comes on for a few seconds then it shuts off again. Did this maybe 5 times with same result. Un plugged it from power for a minute plugged it back in started up fine. And holding the power button the startup options window never did appear.
Also at one point Mac Studio at start up asked "choose to mirror or extend display from the menu" but there is no menu on the screen. I use 2 monitors. I had to unplug one monitor form the computer, restarted fine, then plugged monitor back in.

Hi from Portugal,
My M2 max has the same problem, it´s in apple repair for almost 3 weeks, it seems that they are replacing all the interior and still has the same problem

I'm having the exact same issue, Mac M2 Max (2023) won't power on, with a brief flash on the power light indicator. At the Apple Genius bar they did a firmware update that temporarily fixed the issue, but only for a couple of weeks. The issue seems more progressive, sometimes a few weeks, then once a week, and then every other day to everyday.
Apple store replaced the Logic board, and the bus bar. Then having spent a day sorting out the glitches from a time machine restore, less than a week later the power on fault has returned! It's not a boot issue, its a power related issue, for some reason the Mac after shutting down switches off the power supply internally like in a standby mode and won't reset after pressing the power button again. I don't recommend repeatedly pressing the power button when this fault occurs as that once that resulted in the power jolting back to life causing a recovery screen to appear.
The easiest workaround is switching off the power supply Mac from the wall after shutting down. It's frustrating as its not functioning correctly. Albeit once powered on the Mac behaves boots perfectly, not issues at all when up and running, and no matter what peripheral is plugged in.
I think at this point we need to get some more information from other users having the same issue. I can't entirely rule out a hardware glitch with external devices, but why this hasn't occurred previously as i had the same hardware, drives, monitor and USB hubs connected to the Mac Studio for nearly two years without an issue.
Mac Studio M2 Max (Oct 2023), 64GB, Sequoia 15.5
Connected to mains supply via Masterplug extension lead with surge circuit
Monitor: LG Ultra HD, connected via USB3 cable to displayport input on the display (not using HDMI on the Mac)
USB drive docking stations: 2, via USB A, and USB 3
1 external SSD drive: connected to USB 3
1 USB 3 hub - TP-link 7 port:
Genuine Apple wired usb keyboard (2015)
Wacom intus tablet
Papalook webcam
USB dongle for Tecknet wireless mouse
Brother printer (USB)
I've tried unplugging these devices one at a time with no effect when the fault occurs, except for the monitor.
However my gut feeling too still points to the PSU itself. Looking at my Apple repair schedule the authorised work included the 370W Power Supply, however the work confirmation on collection only includes the logic board and Bus Bar as being carried out.
