Macbook sleep wake kernal issue

You can try installing macOS to an external USB drive to see if the problem occurs while booted to the external drive. If the issue does not occur while booted to the external drive, then you can feel better about getting the SSD replaced. Testing with the while booted to the external drive also may help you to discover if the SSD is dropping offline when the laptop goes to sleep. If you wake the laptop while booted from the external drive you can check the Apple System Profiler (Option-click the Apple menu and select the first item) under "SATA" to see if the information for the internal drive shows up. I suggest checking there before a problem appears so that you know what information should be there. If you leave the System Profiler app open, then you will need to use Command + R to refresh the information in the profiler to get the latest information. If nothing shows up under "SATA", then check under "NVMExpress", but I'm fairly certain this laptop only uses a SATA based SSD. If the internal SSD disappears when waking the laptop even if the laptop doesn't have a Kernel Panic or unexpected shutdown, then you can be fairly confident the SSD is at fault.

Unfortunately the posted log doesn't provide any useful information.

See if there are any Kernel Panic logs. These logs have a file name beginning with "kernel" and ending in ".panic" and can be found in "/Library/Logs/DiagnosticReports". If there are any panic logs please post several of them here using the "Additional Text" icon which looks like a piece of paper.

When performed the clean install did you test the laptop before migrating or restoring from a backup and before installing any third party software? Did you erase the whole physical SSD instead of just the "Macintosh HD" volume or hidden Container?

Run DriveDx to check the health of the SSD. Post the complete health report here using the "Additional Text" icon which looks like a piece of paper.

Do you have enough free storage space on the SSD? macOS should always have at least 20GB of free storage space available for the normal operation of macOS.

It does sound like the SSD may be failing even though the DriveDx report does look Ok. You can try unchecking "Put hard drive to sleep when possible to see if that helps. This setting used to be in the "Energy Saver" System Preferences, but in Big Sur it may be on the "Battery" System Preferences. If this helps, then it would further point to the SSD as the problem.

Unfortunately there is no way to be certain of the problem unless you see the SSD disappear while you are booted to an external drive or a Kernel Panic shows an error related to the SSD.

You should be extra diligent about having frequent and regular backups so you don't lose any important files if the SSD finally fails completely. It can be very difficult to impossible to recover data from a failed SSD plus it would be expensive.

If you want to replace the SSD you can find a drop in replacement from OWC (their SSDs will be larger & faster).

You need to find out why the SSD ended up at 72C. Was the rest of the laptop extremely hot at the time or was the high temperature only the SSD? If only the SSD, then the SSD was either being written to non-stop for too long or the SSD is bad. The only way to determine this is to observe the system closely when it happens.

Like I mentioned earlier installing and running macOS from an external USB drive may help you to determine if the internal SSD is bad (unfortunately not all SSD failures can be identified by DriveDx since controller issues don't show up in the report).

If the issue is easily reproducible, then that makes it easier for the repair tech to figure out the problem. Again, booting the laptop externally may help you confirm if the SSD is at fault either because you can actually confirm the internal SSD disappeared or even having no issues occur which may also indicate the internal SSD is bad.

It is all a matter of careful observation and swapping parts. The more reproducible the problem the better.

I had a similar issue where my mac shutdown within 10 mins after boots. Done various diagnostics including visiting apple store.

Finally, i reinstalled (using option cmd+option+r) clean mac on (deleting all content using disk drive), this has solve my problem and no more restarts.

This is great as i was even told my apple guys to replace logic board (costing around £600). You could try this after backing up your data. Thanks
