Hardware Information:

iMac (Retina 5K, 27-inch, Late 2015) iMac Model: iMac17,1

Drives:

Q - disk0 - APPLE SSD AP0032H 24.00 GB (Solid State - TRIM: Yes) Internal PCI-Express 5.0 GT/s x4 NVM Express

Q - disk0s2 [APFS Fusion Drive] 23.69 GB

Q - disk1 - APPLE HDD ST1000DM003 1.00 TB (Mechanical - 7200 RPM) Internal SATA 3 Gigabit Serial ATA

A - Fusion Drives were good in their day for extra Storage and are still functional but at a reduced performance especially in Big Sur and above who work much better with an ALL SSD Configuration

System Software: macOS Monterey 12.5.1 (21G83) Time since boot: About 5 hours

Q - Antivirus software: Apple and F-Secure

A - Should be removed as per Developers Instructions

A - There are no known Windows-like Viruses in the wild that self replicate and affect macOS, because of the underling UNIX  Foundation and Permission Limitation. 

Additionally, and specific to Big Sur macOS 11 and Monterey macOS 12, the Operating System resides in a Sealed and Read Only Volume that can not be opened by the User and protects against from “ Bad Actor “ Software.

The Only thing this Antivirus software is protecting is the Bank Account of the Developers and for zero return to the User aside from the problems this software creates.

AntiVirus Developers purposefully Market their product to create a “ Fear Factor “. In so doing, creating a False Need for their Product.

The The Built in Security  is all that is required to protect the computer.

Am not too good at Reading the supplied reports but an alternative --->

Understand, we are all working Remotely from all around the world. 

Therefore, we do not have the On-Hands experience the User ( you ) has with this computer.

The next best thing for us to having a semi - actual On-Hand experience  with this computer is to follow the steps below

Download the Application Etrecheck directly from the Developer. 

The application is free or paid from added features. 

It will take a Snap Shot -  both the hardware and software.

 The Report will Not Reveal Any Personal Information. 

Post back the Full Report - copy and paste - using the Additional Text Icon ( 3rd Icon to last )

We can have a look at the report for possible issues and may have possible suggestions to resolve the issues.

Uninstall the iShowU software and see if that fixes it

Good catch where is that showing - interested 😀

In one of the panic reports, it lists "com.apple.iokit.IOSurface" under "Kernel Extensions in backtrace".

Then, under the last started and last stopped kexts section, it lists "driverkit" and "AFIVRDriver", which appears to be related to audio extensions based on a quick search.

And then "com.shinywhitebox.iShowU-Audio-Capture" is listed as a 3rd party kernel extension.

I'm not sure what happened to that EtreCheck report. It looks like they may have tried to print to PDF and then copy the text out of the PDF.

Good and if you are satisfied but notice and New Installation PowerMyMac .

This application is akin to CleanMyMac. You may consider removing it.

Certain Applications maybe available on the Apple Apps Store - this only means the Developer is prepared to pay Apple a portion on each sale. What the Application may do to the computer is up to the User to check this out before purchase

Any of the below should be removed as per Developers Instructions 

This will include CleanMyMac and  MacKeeper

Would suggest reading the posting on either or both of the above and arrive at your own conclusion

I will uninstall it, if there is no other way... but maybe somebody else have another solution...

It's just a test. There is no other way to test these things. Remove the software most likely to cause the problem. (And don't install any additional, similar software.) If the problem continues, then it is something else, likely hardware. If the problem never returns, then you've probably solved it. But if this software is required, then you may have to simply live with the crashes.

At this point - would suggest taking the computer to an Apple Authorized Service Centre for evaluation as they have the Special Hardware, Special Software and Special Tools to examine the computer completely and suggest remedies at a Cost.

Only they could answer any and all questions regarding what needs repair or replacement including any Costs

Good catch where is that showing - interested 😀

Thank you for the Report.

I will dissect it in detail,  and get back to you shortly
