    Well I anxiously awaited High Sierra’s release Sept. 25 and installed it. Sorry to say it was macOS high disappointment.It was a fresh install on a Macbook Pro A1278 mid 2012 256gb SSD 8gb memory. Previously Sierra used to startup in 10 seconds. High Sierra took close to 2 minutes and that was on the SSD. I wonder how long it would take on a normal HDD. Very disappointed, I think Apple’s done a Windows 8 here.
