That panic report suggests a **BridgeOS-related kernel panic**. BridgeOS 
runs on the T2 security chip in Intel Macs, handling things like Touch 
ID, Secure Boot, and SSD encryption. Crashes involving BridgeOS can 
sometimes cause spontaneous reboots, especially on Macs with T2 chips 
(like the 2018 Mac mini).

### **Possible Causes**
1. **BridgeOS Bug or Corruption**
    - The panic mentions *Bridge OS 9.2 (22P2093)*, which is likely an 
update from macOS Sonoma (14.x).
    - A corrupted BridgeOS update can sometimes cause recurring crashes.

2. **T2 Chip Issues**
    - If the T2 firmware or SEP (Secure Enclave Processor) has problems, 
it may panic and reboot the Mac.
    - "SEP Panic" suggests an issue with the Secure Enclave.

3. **Hardware Issues**
    - If the Mac has a failing SSD (since T2 is involved in SSD 
encryption), it could trigger panics.
    - Failing power delivery or overheating components can also cause 
instability.

4. **macOS Sonoma 14.7.2 Issues**
    - If the system recently updated, the update itself might be the cause.
    - You could check the system logs in Console.app to see if there 
were update failures.

---

### **What to Check Next**
1. **Run Apple Diagnostics**
    - Restart and hold **D** to run Apple Diagnostics.
    - See if it reports any hardware issues.

2. **Reset SMC & NVRAM**
    - Since the Mac mini has a T2 chip, reset the SMC:
      1. Shut down the Mac.
      2. Unplug the power for 30 seconds.
      3. Plug it back in and wait 5 seconds before turning it on.
    - Reset NVRAM:
      1. Restart and immediately hold **Option + Command + P + R** for 
~20 seconds.

3. **Check for Firmware Updates**
    - Open **System Settings → General → Software Update** and ensure no 
updates are pending.

4. **Look for Repeating Panic Messages**
    - Open **BBEdit** (or Console.app) and search for:
      - `"panicString"` → This shows the root cause.
      - `"BridgeOS"` or `"SEPD"` → If repeated, it's likely a T2 issue.

5. **Boot into Safe Mode**
    - Restart and hold **Shift** until you see the login screen.
    - If the issue doesn't happen in Safe Mode, it could be a software 
conflict.

6. **Reinstall macOS (Without Erasing Data)**
    - Boot into **macOS Recovery** (Cmd+R on startup).
    - Reinstall macOS over the existing installation.

---

### **If the Panics Continue…**
- Consider **disabling Secure Boot** temporarily:
   - Boot into macOS Recovery.
   - Open **Startup Security Utility** and set it to **"No Security"**.
   - Restart and see if the panics persist.

- If **hardware diagnostics show errors**, you might need Apple support 
or a T2 chip replacement.

Does the Mac mini keep restarting randomly, or was it just this one time?

I suspect it has form for restarting (at least in the last year or so). It did
it perhaps a few months ago, and not that long ago I found that iStat Menus
was reporting a CPU temperature of 100C and then it restarted. And then very
recently the temperature was creeping up (was 50C or so) so I forced the fans
to run faster (3000rpm), which helped. Fan speed seems to be back at 1700rpm
(perhaps because of the restart) and temps around 30 to 40C which is a lot
better.

Somewhat busy the next few days but will apply all your test etc suggestions
later in the week.

Thanks for the response.

You are welcome! :-D

ChatGPD says ......

Tim's Mac mini running that hot (100°C) is definitely a *big red flag* 
—it could explain the panics and restarts. Sounds like a **thermal 
throttling issue** where the CPU gets too hot, forcing an emergency 
shutdown to prevent damage.

### **What Tim Should Focus On First**
1. **Check for Dust & Cooling Issues**
    - A **2018 Mac mini** has a single fan and can collect dust, 
blocking airflow.
    - If comfortable, Tim should **open it up and clean out dust** using 
compressed air.

2. **Monitor Fan Speeds & Thermal Performance**
    - iStat Menus is a great tool.
    - **Check if the fan ever spins up properly on its own** or if it’s 
stuck at low speeds (1700rpm might be too low under load).

3. **Reset SMC Again** (Controls fans & power)
    - Since fan speed dropped back to 1700rpm, the SMC reset I mentioned 
before might help get the fans running correctly.

4. **Apply Fresh Thermal Paste?** (If overheating persists)
    - A 2018 Mac mini that has **run hot for years** might have 
dried-out thermal paste.
    - **Reapplying thermal paste** could help reduce peak temps, but 
this requires opening the machine.

5. **Keep Forcing Higher Fan Speeds for Now**
    - If running the fan at **3000rpm prevents shutdowns**, that’s a 
**clear sign the system isn’t cooling properly on its own**.
    - There are apps like **Macs Fan Control** to manually control fan 
speed until a more permanent fix is found.

### **Summary**
Tim’s Mac mini is likely **overheating and panicking due to T2/BridgeOS 
instability under extreme heat.** First, clean the dust, monitor temps, 
and force higher fan speeds. If it keeps happening, a **thermal paste 
replacement** might be needed.

Sounds like he has a plan to check things later in the week—good call!

 You realise who’ve you just responded to? His response is from some AI

DB's just spouting chatgpt shit now is he? How surprising...

My last Intel Mac would do that BridgeOS crashout occasionally too. I
never tracked down a reason and Apple never responded to my Radar posts.

Temperature runaway I'm surprised at, the intel chips have onboard
sensors and thermal management should have throttled that long before
overheat so something very wrong must have been going on. Given that,
I'd do an SMC reset since that's the watchdog that'd cause the reboot as
well as the device that's *supposed* to manage the heat.

What's odd is that BridgeOS is Apple's embedded mini OS that runs on their
various peripherals like HDMI dongles, their headphones, the touchbar,
TouchID, the T1/T2 chips and their onboard SSDs.  Not sure what runs on the
SMC these days (it predates bridgeOS as a thing, but it's possible modern
SMCs also run bridgeOS).  The Intel mini doesn't have a touch bar but it
does have a T2 chip and Apple SSD.

It's hard to say what's causing this particular panic without the full trace
(and I've not seen one before to pattern-match), but having BridgeOS in that
trace suggests it's some peripheral component that's crashing rather than
the kernel itself.  Although I may be over-analysing the small snippet
posted and evil-knievel style leaping to conclusions.

From that backtrace it would be possible to work out where in the kernel
it's crashing, but it appears it is not decoded in the panic log.  It would
be possible to decode it with a copy of the kernel with debug symbols, but
I don't have that.

Last time I did this function names were included in XNU kernels so no
special builds were needed.  Can you upload /System/Library/Kernels/kernel 
and I can check?

(name may have changed slightly in recent versions, I'm not sure)


The PSoC message is odd.  There's the Cypress Programmable System on Chip, a
kind of analogue microcontroller-FPGA, known as the PSoC but I don't think
modern Macs use those.  I'm guessing the PSoC terminology is for something
else Apple-y.  The 2009 MBP17 used a Cypress PSoC 2 (CY8C24794) for the
keyboard and trackpad, maybe they call all their controllers PSoCs or
something?  But the Mini doesn't have a keyboard controller so that's
strange.

⚠️

“kernel” cannot be opened because it is from an unidentified developer.

macOS cannot verify that this app is free from malware.

Plus another outbreak of x-posted crap too when I checked ucsm on NewsGrouper.

My Intel Mac predates T2 so no such problems seen here!

Well I did wonder but it seemed to be missing the usual markers.

In spite of your bad attitude, I still try to help you.

Good luck with fixing your computer.

Yeah I spotted a subtle transmogrification to the nym you pointed out a week 
or so back. I'm sure if you feel the need to get some aid from an AI bot, 
you're quite capable of doing that yourself.
