I've read a lot on here about people saying that Beta 1 of Mojave seems slower than High Sierra. I just recently installed it on my 2012 MacBook Pro (I upgraded it to 8gb of RAM and an SSD). On High Sierra there was much higher memory usage and when I first opened apps (especially Safari) they would sit there with the spinning wheel cursor for a few seconds before I could use them. On Mojave they load right up and I can use them right away. Anyone else notice better performance on this beta?
