iMac suddenly going slow and Beach-balling

Hey folks - looking for some help here. My iMac (Retina 5K, 27-inch, Late 2014 with a 4GHz i7 Processor and 24 GGB RAM) has suddenly started beach-balling and being incredibly slow. I can barely even type this as it can't even keep up with that! I have done the Cmd-Option-P-R reset. EtreCheck report shown below - which doesn't seem to offer much other than confirming that performance is poor.


Any help you can offer would be apprediated.


Sam


iMac with Retina 5K display, macOS 10.14

95% chance it is a failing hard drive. If the problem persists in Safe Boot Mode and on a new user account the best way to confirm it is the drive is to install a copy of macOS onto an external USB 3.0 drive from Recovery Mode and test if booting into that copy of macOS works fine without the beach balls, etc.


If the problem persists there then it's hardware-related, but not your hard drive.
