If your hard disk is getting full, that may well be the problem. My old MacBook Air went nuts when I filled its little 64GB drive. 16GB seems like a good margin, but is it possible you're filling that up with temporary files? Is iCloud syncing more data than you realize?
For what it's worth, I'm not seeing these problems. I'm on the High Sierra betas, but I have been since last summer and I have yet to have serious mail or Safari problems. -- Alex Hall > On Jan 4, 2018, at 16:26, Christine Grassman <cgrassman1...@gmail.com> wrote: > > It seems each week a new irritation is popping up.
