IMac Running Really Slow
My IMac is a the Retina 4K, 21.5-inch, Late 2015 and for about a year now its been running soo slowly. Its fully updated and is using macOS Mojave 10.14.6, however when I want to load anything it takes a very long time. The start up time for it at the moment is around 5-6 minutes before i'm able to (slowly) open the internet.
I've got over 800GB of free space and there isn't anything running in the background apart from Chrome if im on the internet.
I really dont know what is wrong with it and its driving me insane.
Please can someone let me know what this might be and if i can speed it up?
Thanks,
iMac Line (2012 and Later)
