Storage Full But New Computer
I have a new 2017 MacBook Air with 128 GB running Mojave OS. I am getting notifications that the storage is almost full. Disk Utility shows Macintosh HD with 21 GB used, 94 GB other volumes, and 5 GB free. I have installed very few apps and have no documents, photos, or videos stored on the laptop. Activity Monitor does not show anything using an excessive amount of memory. What is on the other volumes? How do I free up storage space?
