If I leave for a few hours, when I come back I have the message that my Mac restarted because of a problem. WHAT PROBLEM? This thing is less than a week old!
this problem:
"panic(cpu 14 caller [...]: cpu14: LLC Bus error from cpu2:
LLC bus is likely a cache bus. Data items on their way from memory are cached multiple levels, and at one point your data incurred a Bus Error.
This could be a one-off error. If it does not look that way, you may have a serious Hardware issue. Luckily if your Mac is new, it has a serious warranty as well.
¿what is the date of your most recent backup, and by what method?
NB>> Genius Bar technicians are NOT trained to interpret kernel panic reports.
if you just make an appointment at the Genius Bar, Genius Bar will only fix your Mac if it fails diagnostics. You may need to work with Apple support to affirm that there is a problem, and if they agree, they will DIRECT an Apple store or an Apple-Authorized service Provider to swap the mainboard to effect the repair.
Also, if your Mac was bought DIRECT from Apple, (not from Reseller of any description) you have 14 days [firm] to return or exchange for full value, for any reason.
if your Mac was acquired DIRECT from Apple, and not through a Reseller of any description, you have a strict 14 days from receipt to return or exchange for Full Value refund/exchange.
Third-party file Sync-ers such as DropBox, BackBlaze, OneDrive, or GoogleDrive can markedly SLOW performance, but are not inherently dangerous.
They were Quickly ported from that other Operating System, and were never re-written to take advantage of the MacOS ‘File System Event Store’. The typical brute-force search they use takes all afternoon for one pass. That relentless searching is a completely un-necessary waste of resources.
Synch and Backup programs like iCloud Drive and Time Machine that DO use the MacOS File System Event Store can find changes really quickly and be done with their work and suspend themselves. Time machine can run backups Hourly, while all those others are still beating on the file system for the first pass, four hours later. By the time they have finished, they need to start again.
You can't cause a Bus error except by having a hardware problem. And yours is specific to LLC bus that is not accessible to software at all.
You have a hardware problem.
Having the same issue. A little bit different panic dump though . . .

Any educated thoughts?

If you are not happy with this work-around, then send Feedback to Apple using the following links.
Thank you so much for the fast response. It seems to happen a few times a day. I am really trying to avoid having to bring it in for service since it is mounted inside a chassis in the main rack of my recording studio. Do you have any suggestions to anything I can try before having a tech come over to remove it?
So you can tell for sure from that report that it is a hardware problem? Someone told me it might be a kernel panic from a software issue, but I think you seem to know a lot more about this than he does.
Thank you for your analysis.
My Mac Studio is a 2023 M2 Max, 64GB ram, 2TB disk.
I have a 27” Studio Display - directly connected and a 27” Dell monitor via direct HDMI.
The panics are ‘common’ with the occurrences seeming to be happening more frequently-sometimes multiple a day. Other times less often as in days apart.
I’m disconnecting peripherals [OWC 14 port bridge etc.] and will start disabling startup programs.
i suspect, maybe, it might be my screen saver [world map w/ solar and weather] or the driver app for an ADA mouse [Contour roller mouse].
Overnight the problem wasn't present. I have the OWC Dock disconnected, not using the Contour App but still have the screen saver running. The OWC Dock has a DisplayPort but that isn't in use.
Mahalo for your assistance!
it seems like this specific issue should only be possible when you are telling a display to stop (and it does not affirm that it HAS stopped within ten seconds).
So at times when the display stays on all the time, or Off all the time, I would not expect to see that same issue at all.
FrankBear--
Your post will be here for a long time, and readers may find your post by searching the internet for a similar issue.
Could you please summarize how you fixed this problem, and what more you learned that might help others in a similar position?
Thanks very much !
Been having this same problem with a new Mac Studio - all updates have run, attached to a BenQ 32". monitor. I come in every morning and a rebooted message is displayed. I just exchanged a Mac Studio for this one because it started rebooting literally every five minutes. This one was fine for awhile, then it started doing it overnight and then yesterday it did it in the middle of a Photoshop work session. Report is below for reference but after the first couple of times, I found the sleep setting suggestion here and have made the changes as suggested and thus far, there have been no further issues...
---------------
...and literally as soon as I posted a few minutes ago that the power saver adjustments had seemed to resolve things, it happened again! This time it was in the middle of a video playing. Everything suddenly froze for about 10 seconds, then a flash of color and a reboot. Exact same thing as the last machine was doing...

Report attached below)
My last backup was a few hours ago. It backs up all day to BackBlaze.
Hey Grant,
I just opened a new topic about a very similar issue.
Your input would be much appreciated!
Regards,
Ben
I have been having the same issues with my Mac Studio.
Brand new Mac Studio restarts because of a problem all the time
