Getting Adobe Illustrator CC 2020 onto your Mac can be a bit of a process, especially if you're looking for a version that’s already patched or "pre-activated." While the convenience of a "one-click" install is tempting, it’s important to know exactly what you’re downloading and how to set it up safely.
