Yes, for the most part, 512GB is enough space for your Mac. However, it depends on what you use your machine for. If you use your machine for video editing or photography, you may want to greatly consider upgrading your solid-state drive. This is also true if you use your device a lot for gaming. However, if you simply use your machine for everyday tasks, or don't find yourself using a lot of processor-intensive apps, 512GB should be plenty for your device.
