Good job apple for slowing down old macs. New sales coming in.

Big sur is a wrong name. Bug Sur is the best fit. #BUGSUR Let's make this a trend so apple notice this and provide a fix.

Same here. MacOS seems very laggy now. Windows on bootcamp is way faster on boot than Apple's macOS itself. I regret I upgrade, no easy way to downgrade. I hope Apple will release an update/fix for this.

Same here Macbook pro retina 13 inch late 2015 Very big difference on performance. Boot time at about 1 minute and slow response on opening apps. Is this Apple's marketing strategy for us to buy new one?
