Hi there,
I hope you having a good so far!
I can help you to download Adobe illustrator on your own MacBook Pro easily with no problems, as well as it will be activated with no problems.
I will install for you the required illustrator version "2018".
Also, I've worked a lot on Adobe illustrator on my MacBook as this is my main work already beside the photoshop, InDesign and many other photo editing software.
It will include the CC in case of using the online cloud to help you have the elements of your project where ever you you go just by accessing your Creative Cloud account.
Best regards,
Amr Ahmed
