Now you’ve cleaned up…

Keep everything shipshape, so you needn’t go through this again…

Once your Mac’s in perfect working order, keep it that

way. Don’t install apps on a whim, and periodically get rid of ones you don’t use. Keep tabs on your downloads, and use tools we’ve mentioned to find large files. Automate keeping folders tidy. Most of all, ensure you won’t lose data. After tidying up, clone your Mac to a drive you stash in a drawer. Then keep your data safe by backing up regularly to a local drive and to the cloud. We use Backblaze below, for which you get a 15-day free trial; after that, it’s $5 (about £4) per month per Mac.
