Something is slowing my Macs down. Is Mojave using more VRAM, off loading CPU to GPU now, or is the GPU just being used more now with Metal? it seems a lot of computers have slowed down (including my 1311A iMac, 2013 model 27, inch with SSD,1 GB VRAM and 32 GB RAM. Even my 2017 5K iMac 27 inch 3.8 Ghz with 40 GB RAM and Radeon PRO 580, 8 GB card, Fusion and SSD (external 1TB Thunderbolt 3) seems slower in certain apps. (Safari specifically, Pages at times also) I have a 2014 MacBook Pro as well, no updates since 2018, and it has not changed in performance, This is why I'm asking.
