Clean up your Hard Drive with "CleanMyMac";
The biggest chore of your Mac housekeeping efforts is reclaiming space on your hard drive. I'm fairly certain there are files and applications on your Mac that you no longer need. Your Mac has a utility to root out evil, and there are a handful of free apps that will also help you clean up your hard drive. The Mac Utility I will recommend is the App called "CleanMyMac". It is a paid for App.
First, to start cleaning your hard drive, open your Mac's built-in Disk Utility program and click on your hard drive in the left panel. Make sure you are viewing the First Aid tab and then click the "Repair Disk" button in the lower-right corner. This will run a lengthy scan of your desktop, making repairs as necessary.
To clear the cache that your Mac's various applications and processes have stashed on your hard drive, install the free utility, OnyX. It's a fairly extensive program, much of which I will not cover here. For our spring cleaning purposes, I will direct you to the Cleaning tab at the top of the app. Here, you can check off items across six categories, Clicking [ Execute ] to delete the cache of the checked items, freeing up hard-drive space.
Then Install and run "CleanMyMac. Utilize the App as much as you can. It is a very powerful tool.
