A 2011 iMac cannot be upgraded past macOS 10.13 High Sierra. This will not support the 2022 versions of CC products.

You will either need a newer Mac or to install InDesign CC 2019.

your computer needs to meet specs:

'

to support id cc 2022.  does it?

** there are 3 ways to contact adobe; chat, phone and twitter:

chat:
use a browser that allows popups and cookies, and click 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.

phone:

twitter:
tweet @AdobeCare

p.s. if you're contacted by anyone (via email or private message), it's much more likely to be a scammer than an adobe representative. ie, double check for an employee badge if contacted in the forums and look for an adobe.com domain in the email address if you click reply to an email. then check again and be very suspicious. any other method of contacting (or offering to contact you) is almost certainly a scam,

What version of macOS? How much RAM?  A screen shot of "About this Mac" may be helpful. I am not hopeful, I have to say.
