Don't you just hate it when you're in the middle of something, you're in the zone, then the beachball of death arrives to slow you down just when you're at your most productive? I'm finding newer Macs to be comparably slower than the old ones with all the extra apps we're throwing at them and the expectations for multi-tasking. For work I need at least Outlook, Calendar and Chrome open just to do my basic tasks, then I might need extra apps to do specific functions throughout the day. I've checked to see if I've max'd out my disk space - this wasn't an issue. I checked for malware and adware - nada. The culprit? Apple's own slick display parameters.
Yes, those beautiful background graphics that you can see through transparent menu bars are costing you precious system resources, slowing your mac down to a snail's pace just at the time you needed things done 10 minutes before.
To rectify this, reduce the transparency in the accessibility preferences as shown below. The only impact is your menu bars will now be opaque rather than transparent, but the Mac will run faster on other tasks.
Open System Preferences.
Select Display, then tick 'Reduce Transparency'.
Have fun with your faster Macbook!
