Question

Adobe Acrobat Synchronizer & CEPHtmlEngine keep hanging & then all my other apps hang

I'm working in Premiere, AfterEffects (not Acrobat) and have Chrome open.  
Running Catalina 10.15.3 (19D76) on an iMac (Retina 5K, 27-inch, Late 2015).

 

Premiere or AfterEffects will all of a sudden hang, or Chrome will hang, and then everything hangs and goes unresponsive.  Nothing will Quit–– not even Force Quit will work.   Activity Monitor registers "Adobe Acrobat Synchronizer and CEPHtmlEngine as not responsive--- before anything else shows as not responsive.

I wind up needing to hard restart the computer.


We're talking about needing to do this over 20 times a day.   I very badly need a solution.  This is untenable and I'm unable to work.

I'm experiencing the same problem. My macbook will all of a sudden get very loud and when I look at Activity Monitor it's because Adobe Acrobat Synchronizer is hanging/taking up tons of disk use. Following in case a solution comes up. For now I've just been killing it everytime it happens, but there has to be a better solution.

Adobe Collab Sync is probably in the user or system library.

 

1. Click on Go>Go to Folder and type ~/Library to access the user library. Navigate to Application Support/Adobe/Acrobat/DC and delete the Collab app/file/folder. 

 

If its not there,

Hi,

 

Is Chrome browser using the new Adobe Acrobat extension?

 

Seems like similar issues also happen with the  Internet Explorer browser with add-ons interacting with something when the CC Desktop App is in use.

 

For troubleshooting purposes you can try disabling the CC Desktop App and check how Adobe Acrobat behaves when you open it.

 

In any case see if this guidance from Adobe: https://helpx.adobe.com/x-productkb/global/high_cpu_usage_cephtmlengine.html
