Hello,

Have you run Disk Utility's Disk First Aid on all connected drives?

Are you running any VPN, Anti-Virus, or Cleaning apps?

We need to see what all is running, a report from this will not display any personal info...

What version of InDesign are you using? Adobe does have a Silicon version, but if you transferred it from your previous Mac, then it is using Rosetta and not taking advantage of the faster processor. Adobe did release the latest update this month to address a number of issues with their program. It is an Adobe Issue as they are the only ones that can provide the updates necessary for the ideal user experience.

You will see the many problems they have been addressed in the previous versions by Adobe. Believe it or not, Apple has no control over any of these problems, and they are only resolved by Adobe.

If you can provide the Etrecheck report suggested by BDAqua, we might be able to pinpoint some likely culprits that could be slowing your iMac down. This will save us from playing 20 questions in order to drill down to the root cause.

How do I upload the report?

Start by opening a Reply window here. Then open Etrecheck, copy the entire report to your Clipboard, and paste it into the Reply you started using the Additional Text icon BDAqua pointed to in his suggestion.

Ask Adobe. InDesign is an Adobe product, not an Apple product.
