Make sure you’re using the most recent version of your operating system. Your updates might run the gamut from improvements to security and performance to more sweeping updates of your OS. Navigate to Apple icon > App store, click the Updates tab, and then install the recommended updates to your Mac’s OS. If your system software is out of date, updating it could do a lot to improve your device’s performance. The first thing you should do when dealing with a sluggish Mac is update the OS. Update your OS, reduce login items, clean out your storage space, and optimize your system to enjoy a Mac that works like new again. You may be able to revive your Mac with a few simple steps you can take at home. When your Mac starts slowing down, is it time to get a new one? Not necessarily.

It’s not unusual for a Mac to slow down as its operating system (OS) becomes outdated and years of use eat up its storage capacity.
