My Mac is just running far too slow. Plenty of memory available, takes forever to open anything, late 2015 model running whatever the latest update was. It’s very frustrating. Loads of wifi signal strength, hi speed data link. Bright ideas welcome, well any ideas really
thank you

Delete Norton, if it is still installed.
The reason your iMac is slow is due to the 5400rpm hard drive. Very slow. If you use an external SSD and run macOS from that it will make your Mac 10 to 30 times faster for storage. For more info, instructions, and what SSD to buy, please read: How to Setup and Use an External SSD as y… - Apple Community.
However, something else that concerns me is "Kernel panics - This system has experienced kernel panics. This could be a sign of hardware failure." Please Use Apple Diagnostics to test your Mac - Apple Support and let me know the Reference Code.

Hi Suilven1272,
I have a hunch this is due to a slow hard drive, but to check, I believe we need to proceed with an EtreCheck report. EtreCheck is a useful app to diagnose and identify issues, both hardware and software. It is trusted by many users. Please follow the steps outlined below:
Cheers,

Hello, well that took me places I have never been, the report was No Issues Found ADP000. I took Norton off earlier today
Computer is now restarting in recovery mode and I’m looking at a white rectangle
thank you
Oh, sometimes it does that from Diagnostics. Simply power off. It will then return you to normal mode. You can read about using an external SSD as your Startup disk (that I linked earlier), and running macOS from it. That will fix your slowness issue.
Thankyou Jack-19. I’ve had a look at the external SSD information and will work through it tomorrow. You have been a great help and I am way further forward then I was, being somewhat in a state of kernel panic myself.
Thank you for the effort you have put in to help me, timely, helpful and detailed. Good job!
I think that's it Jack-19, the instructions were clear so this should be what you need
thanks!
Thanks Jack, I’m running Etre now, will post the results when they appear.
Thank you for your quick answer, I really appreciate it
I await your reply with EtreCheck!
Why are you starting in Recovery Mode?
That is an interesting question, the Mac just sort of took me there, there was an option to just restart, which I think I should have taken
Jack-19,
I sorted this out over the weekend with new SSD following your instructions, this is like having a new computer. Thank you again for your timely help and support
