If your drive is filling up, then you need to do some maintenance to clean things up and free up space. On my 1TB drive, about 267GB is free so I’m using about 74% in total.

Start with a quick check of your disk space utilization. Fancy cursors? A desktop photo that changes every few seconds? Streaming network backup services that are always on, always scanning? Those can all be problematic. Though Mac users seem a bit less susceptible to adding little extensions and add-ons to their system than their PC brethren, it’s a good idea to also check your own Mac to ensure you haven’t added anything that you don’t really need.

Whether you’re on a Mac, a PC, or even an Android tablet, there are some programs that demand more resources than others.
