I purchased the Apple Mac High Sierra via Amazon. I had to take my desktop to Geek Squad at Best Buy due to my system running extremely slow. Upon started it would take for ever to load. I was advised that the macOS High Sierra is OBSELETE and unsupported as of November 2020. Basically upon diagnostics my computer had 16 FAIL out of 20. Now I’m looking to purchase another computer. 🖥️
