Before you do anything, try emptying your Bin. A lot of times people delete files and applications, but forget to empty their bin. The files in the Bin will not clear up storage unless they are deleted from the Bin.
How to Empty your Bin:
1. Right click (if you have setup "Right Click" in a previous solution).
2. Once you have clicked "Empty Bin" option, it will then double check with you if you are sure you want to permanently delete items in the Bin. Select "Empty Bin" again if you are sure you want to erase these items.
How to Clear Up Errors Using Disk Utility:
1. Click on Launchpad.
2. Search "Disk Utility" and click on it.
3. Now, on the sidebar of "Disk Utility", Select the desired drive you would like to clean (mine is "Macintosh HD")
4. On the top of "Disk Utility", click on the "First Aid" option.
5. Select "Run"
6. And hit "Continue"
