Uninstall Useless Apps
If your Mac is running out of space, uninstalling useless apps can help free up some space. It's possible that you may hesitate to delete some game applications that you downloaded ages ago, but if you're not using them now, then removing them can help you create more space for new files and applications.
Please pay attention to small applications that you think don't use Mac space, but in fact, they still take up space even when you don't access them. So, deleting small applications is also necessary.
