I left the computer for about an hour and a half and the result was to find it rebooted.

I tried to reinstall macOS from recovery this afternoon but the problem is still here.
Could this be an issue only affecting M2 Macs?
 
Finally, after another reboot, a crash report was displayed. I was finally able to make the report to Apple.
Usually when rebooting, nothing would appear. However, I confirm the generation of a .panic file: it's the kernel.

Same issue here: Mac mini M1 - 16Gb - Sequoia 15.1.1
I'm not sure if it happened with 15.1 to be honest... By the way I hope it would be solved soon. I don't know if I've done the last backup because of that, better to do it again.
 
Sequoia unusable on my M2 Air.
My opinion is Apple Intelligence caused damage on a whole os.
I tied clean disk and reinstall and disable Apple Intelligence or use 15.2 beta but still unusable.
"Unusable" for me random restart, battery drain, memory leak, slow internet speed
Now I think will rollback to Sonoma never return to Sequoia.

if you did a clean disk install and did NOT enroll in apple intelligence then how could it be apple intelligence that is causing the instability? With that being said, 15.1 is riddle with bugs, can't wait for 15.2 to come out. maybe this upcoming week we will see the golden master of 15.2 which i will go ahead and install

I think apple intelligence is integrated on a core OS if you turn on or off will cause the same because they add some component in os. I use M2 Air with Ventura and Sonoma not face with these issues before in stable version
Kind like putting strawberries in a cake. Even if you don't eat the strawberries in the cake, the taste of the cake tells you that there are strawberries in this cake.

I doubt it. You need to explicitly enroll into Apple intelligence and be APPROVED by Apple before it gets pushed to your Mac. There’s no mention of Apple Intelligence throughout macOS Sequoia at all until you go through the enrollment process.

I mean it could be anything about the code or some other incompatibility in sequoia that might be causing issues.

but there are definitely execution paths still built into the os that just aren’t exposed to the end user on a device un-enrolled in Apple intelligence. And they could very conceivably cause stability issues.

Regardless of what the actual cause is, though, to me the biggest problem with all software vendors these days is that stability and usability have taken a back seat to features that can be marketed to drive sales. It literally doesn’t even matter if the feature works, just that they can make a commercial saying that it’ll transform your life*

I have similar problems on iMac pro, if I have any system monitoring apps like istat menu running. As long as I don't do that, there is no problem.
 
Would not surprise me if Sequoia was doing semantic indexing regardless whether you have ai enabled or not. After all, you could decide to turn it on at any time and it would be a better user experiencen if ai started working right away rather than make you wait hours or overnight to index all your data

That’s the thing though. When you enroll to get Apple intelligence on your system, it can take from
Minutes to Hours until you get approved and the features are downloaded and pushed on to your device.

Once it's out of beta, you'll probably get it right away. Well, after it downloads
 
There is a very simple logic to it:

find the Third Party App or most likely so called "Tool" or ? that is causing it with EtreCheck.
 
The RC of iOS 18.2 just came out. Maybe the RC of MacOS 15.2 will come today as well to fix and optimize MacOS
 
A question for my fellow adventurers: do you use an external Thunderbolt device? Like a hub or external storage?
Because I tried to debug with GPT the only .kernel I could get from the constant reboots and it identified a problem with storage, and excluding internal storage, I have a Thunderbolt hub with integrated storage and several Thunderbolt cases with external NVMe disks. Rebooting without Thunderbolt devices connected has only happened to me once in the last month, so I can't rule out it happening without it, but using the desktop computer connected to the Hub or external drives a lot I can't rule out an incompatibility.
Please let me know. It won't do any good, as Apple is totally ignoring us, but at least we can better understand what's going on.

FWIW I see the same random restarts on MBP M3 especially during the night after put to sleep.
An impression is presently that using "Apple > sleep" or using "command+option+q" results in higher (or quicker) restart than when closing the lid.

Btw it could very well be coincidental but I just realized that I recently added Rosetta. Anyone else same?
 
Since installing macOS Sequoia, I’ve been experiencing significant stability issues on my 14” MacBook Pro M2 Pro. Initially, the system even attempted to restart while I was actively using it, prompting a message about ongoing apps being closed. After a series of updates, this “persistent” instability has gradually lessened but hasn’t disappeared entirely.

Often, when I leave my Mac in standby with applications open (such as a browser, VS Code, Slack, Outlook, Telegram, etc.) and step away for lunch, I come back to find everything reset. After logging in, I notice that the Mac has restarted with no error message on the screen. Sometimes, if I have an unsaved Excel sheet open or a UTM virtual machine running, I’ll find an alert saying the Mac couldn’t restart because a specific app couldn’t close. This, in a way, prevents the restart and saves my work.

I’ve tried everything I can think of, including maintenance with Onyx and, more recently, purchasing BuhoCleaner, hoping it might help, but nothing has worked. My Mac continues to restart randomly during standby—not always, but often enough to be frustrating.

I even attempted a system reinstallation in the past (with both macOS 15 and 15.1), though I restored my data using Time Machine afterward since I can’t start completely from scratch. Yesterday, I installed macOS 15.2 beta 2 in hopes of improvement, though I’m not optimistic.

Has anyone else encountered this issue? Could it be related to the kernel panics reported by users in the past?
So I've had this problem too since installing Sequoia -- returning after >40 minutes or so to find my Mac has restarted, closing all of my apps and having to reload everything (rarely is there a "Your computer was shut down because of a problem ..." error message). I have a 2020 Intel (non-M - so no access to Apple AI, even with Sequoia) Macbook Pro. I've spent hours with Apple Support online, doing everything but a fully clean install on my Mac. I even took it into an Apple Store, and they ran a "revive"(?) on it, which took about an hour.

I'm still getting the same problem, but I seem to have isolated it to the attachment of peripherals. I have a ~5-year-old Dell monitor and run two Thunderbolt cables, one for the display and another that (I think) runs data from the USB hub on the back of the Dell monitor. I have an ethernet cable running to a USB adapter that goes into the monitor, for example.

When I unplug both the display and auxiliary Thunderbolt cables from my Mac, it DOES NOT restart when it goes to sleep. It's a bit frustrating to have to unplug the cables when I go to lunch. Any thoughts on how I might be able to fix this? Thanks!

With your contribution you confirm my concerns expressed in this message:

Considering that it is impossible that all of our HUBs/Displays with Thunderbolt ports have failed at the same time since the introduction of Sequoia, at this point it is clear that the problem lies in the Kernel that has created some incompatibility.

If other users also confirm that they are using Thunderbolt devices connected to the computer when the problem occurs, we will at least have identified the cause.

Now the problem is getting Apple to understand this and hoping for a solution.
