Check Hard Drive Free Space
To ensure that your Mac’s hard drive does not become full, you should periodically check how much free space it has left. If you run out of room on your Mac’s hard drive, you will not be able to install more applications or create more documents, and your Mac’s performance will suffer. To ensure your free space does not become too low — say, less than about 20 or 25GB — you can check how much free space your hard drive has left.
You should check your Mac’s hard drive free space about once a month. If you frequently install programs, create large files, or download media, you should check your free space every couple of weeks.
