Frequent kernel panics

Hi Apple community! I have a Retina 5K 27-inch iMac 2017 with 64 gigs of memory and a 1TB hard drive that has worked amazingly the entire time I've had it but has now randomly started restarting with random kernel panics. My computer is up to date on the latest OS. I have not come even close to filling up my 1tb hard drive because I use external drives so it's not from an overloaded HD.


There didn't seem to be any rhyme or reason to them in terms of time between restarts and what's happening on the computer during them. I've tried a lot of different things to figure it out. So far I have tried:


• Shutting it off, unplugging, waiting 15 seconds, and plugging back in

• Disconnecting all external hard drives or anything plugged into it and am using an Apple keyboard and mouse

• I've run First Aid on Disk Utility on the hard drive

• I've booting in safe mode

• I've run Apple Diagnostics on it and it said there were no issues

• I've re-installed my RAM to ensure it wasn't that

• I've reset the SMC and PRAM

• I've deleted some old applications in hopes it was that

• I have re-installed OS


Next steps will be taking to Apple but I live far away from any Apple stores and am hoping to figure this out on my own but it's looking less likely that I will. It's now restarting with kernel panics about every 15 to 20 minutes.

Hi there!


I wouldn't get a new Mac just yet! It's possible the kernel panics are caused by a software issue, so a new Mac wouldn't help.


First, have you tried an erase and reinstall of macOS?


You can also try running a drive-health utility, such as SMART Utility, which will tell you if your hard disk is failing. If you try this, report back with the results.


Have you tried using another macOS user account on your Mac? Occasionally, a user account may experience a problem, which leads to kernel panics. You can learn about creating a new user account for testing here: Add a user or group on Mac - Apple Support.


Can you also confirm what version of macOS you're using?

Have you installed and run any "cleaning", "optimizing", "speed-up", anti-virus or VPN apps on your Mac?


• I've re-installed my RAM to ensure it wasn't that


Where did you get the additional RAM? Have you tried to rule out the 3rd party RAM by running with the original Apple RAM to see if the panics stop and then replace the extra RAM and test again?

Is the 1TB drive Fusion/Mechanical? If yes, I would consider replacing your iMac with new. IMO the HD is not worth replacing internally or even externally with an SSD. A visit to the Apple Store also isn’t worth the trouble - you’ll get an expensive repair estimate and no guarantee it’ll fix.


Good luck!

Hi!


Yes, I have tried erasing and reinstalling macOS. I've also tried running Apple Diagnostics and it said there were no issues found. I included these 2 steps in my original post about what I've done to try and troubleshoot to no avail so far :(


Yes, I tried using another user account as well as trying to use it in safe mode and I still was getting kernel panics. Not sure what to do!


Thanks for your help :)
