I just upgraded to macOS 11.3.1 and I use Adobe cloud InDesign 16.1. ID has slowed to a crawl. Takes FOREVER to even cut and paste. I've reset all my preferences, hasn't helped. What can I do to fix this??
How much RAM and spare disk capacity do you have?
Do you have a third-party application installed, such as a font manager?
I have a really stout iMac.
32 GB Memory
iMac (Retina 5K, 27-inch, 2019)
Processor: 3.7 GHz 6-Core Intel Core i5
2 TB storage
I have a Font Book app but that's it
I have only used half of the storage, all my other applications work fine.
I have now downgraded to ID Version 15.1.3. My mac works great and fast now. Shame I can't use the latest version of ID with Big Sur.
How does one downgrade? I am having the same problem.
Sorry to hear about your experience about the performance of the app. I'd recommend trying to follow the suggestions given on this community post(https://community.adobe.com/t5/indesign/resolve-slow-performance-and-unexpected-behavior-of-indesign...).
Let us know if it helps.
