Make Your iMac Run Like Lightning Again

As a photographer, I know how important it is to have my iMac running fast. I need to move seamlessly from my SD card to Lightroom to Photoshop and back again. After months and years of hard use, though, your iMac will inevitably feel slower than the day you bought it. Let’s change that!

Get the Latest macOS and Updates

install macos high sierra

Apple releases new OS and updates for a reason: they get better. The updates directly address problems with previous versions. So, if you’re noticing your computer crashes a lot when you’re using Lightroom, for example, Apple might have a fix for that in their latest update. To check for an update go to the App Store and click Updates. If you need to download something, it will tell you.

macOS Sierra is the latest OS, but High Sierra is coming. If you’re too far behind on operating system updates, you’ll notice slower performance.

Repair Disk on your MacBook Air

Apple gives you a free tool in within the Disk Utility section that repairs your Mac hard disk. 
 
To run  your Disk Repair,
  • Choose Apple menu and then Restart
  • As your Mac restarts press and hold the Command and R keys until the Apple logo appears
  • Click Disk Utility and then Continue
  • Select the disk you want to repair
  • Click the First Aid button
  • Click Run

 

Find Out Which Programs Run at Start Up

Some applications set to start when you turn on your computer and they run in the background the whole time. This sucks power and processing— slowing down your experience.

Tp check your startup programs, go to System Preferences > Users & Groups > Your Username. Select Login Items. This is everything that starts when you’re computer starts. If you don’t use the program every single time you’re on your computer, it shouldn’t be running. Choose the “-” sign and remove unnecessary applications from startup.

You may also want to look at your Activity Monitor. Get to it from Spotlight or Applications > Other. This will show you which programs are pulling the most CPU. If you see something pulling a high percentage that you don’t recognize, it’s time to track down what’s going on. Clean My Mac 3 does this automatically. Or, you can manually investigate.
