I have a Mac and I upgraded to Mojave just so I could use Animate 2021, and the reason I did that was because I wanted to use the fluid brush.
Now the reason I used High Sierra was because the future updates were slow and buggy, and both Mojave and 2021 are slow for me so I was wondering if I could get some sort of download link to Adobe Animate 2020.
to get a cc 2020 download link:
using a browser that allows popups and cookies, contact adobe support during pst business hours by clicking here, https://helpx.adobe.com/contact.html?rghtup=autoOpen
in the chat field (lower right), type AGENT
be patient, it can take quite a while to reach a human
Thanks this helped!
2020 performed better for you? I had the opposite experience.
