InDesign CC 2017 is taking 15+ minutes to launch. All of my Adobe apps have severely long launch times but ID is the worst. I have reset preferences. I have transferred preferences from a new user account (which only exhibited a minor improvement in launch time, anyway). I have uninstalled and reinstalled the application via The Creative Cloud app. So far nothing seems to help.
It was only because I had stepped away from my Mac that I found out it does eventually launch. Note that it is not crashing during launch. It also consumes most of my machine's computing resources while this is happening.
I have not tried uninstalling and reinstalling the Creative Cloud components.
I'm just posting to see if there's anyone else who has experienced the same situation.
Caveat: I am running the latest MacOS 10.12.4 Beta (16E154a) MacPro 3.5, 64GB RAM. SSD for all drives.
I would try to delete the caches and if this doesn't help delete the preferences.
Before you delete the preferences I would make a copy of them.
On the mac you find the preferences if you go:
-> Start InDesign - Window - Utilities - Scripts
There you marke «user» then from the flyout menu you choose «reveal in finder».
Then you close InDesign
After that you go back two or three directories in the finder and rename the preferences.
Hope that hekps
