Why is my iMac working so slowly? 2012 iMac macOS Sierra 10.12.6
My machine is working very slowly and I am unsure why. Even loading a webpage in chrome or starting up spotify takes ages.
I have 787.24GB available of 999.35GB for storage. 8GB of memory installed. I have tried emptying the trash and some other things with no luck.
Any help would be great.
