CEPHtmlEngine slows Computer (Mac) and solution.

Hello Adobe and CC users,

I saw there are already other posts about the "famous" CEPHtmlEngine, I got a new (2 months old) iMac 27 Retina (with the highest config.) and I noticed that when i launch (for the 1st time) any of the Adobe CC programs (it can be InDesign or Photoshop or another) they very very slow. It seems that something is making the CPU working a lot. After a little time spent in the Mac Task Manager i found that CEPHtmlEngine copy itself two to three times and each copy "calls" the CPU at least 20/50 times. I found a momentary solution by manually closing all CEPHtmlEngine. By doing this all programs work fast and well as usual and there are no errors or problems. You have to close the CEPHtmlEngine and not the CEPHtmlEngine Helper: the helper is just the "son" and if you close it the engine will create another one. Last thing: the CEPHtmlEngine will not appear again until you restart the computer.

This worked on my computer so I just wrote this to give Adobe (one more) notification of the problem and to give all Mac Users a solution (it could work on Windows too but I cannot try it) that can be helpful until an upgrade will fix this.

P.S.: I got the CC software and all apps upgraded to latest version.

Hi days_of_speed,

Could you please try out the private build of Design Library (Shared Files - Acrobat.com), which has a potential fix for the CPU usage issue?

1. Move the old Design Library extension to somewhere else (move to your Desktop for example):

Photoshop: /Applications/Adobe Photoshop CC 2015/Adobe Photoshop CC 2015.app/Contents/Required/CEP/extensions/com.adobe.DesignLibraryPanel.html/
Illustrator: /Applications/Adobe Illustrator CC 2015/CEP/extensions/com.adobe.DesignLibraries.angular/
InDesign: /Applications/Adobe InDesign CC 2015/Resources/CEP/extensions/com.adobe.DesignLibraries.angular/

2. Download DL.zip from Shared Files - Acrobat.com, then extract it to

Photoshop: /Applications/Adobe Photoshop CC 2015/Adobe Photoshop CC 2015.app/Contents/Required/CEP/extensions/
Illustrator: /Applications/Adobe Illustrator CC 2015/CEP/extensions/
InDesign: /Applications/Adobe InDesign CC 2015/Resources/CEP/extensions/

The final directory structure should look like:

.../extensions/

|-DL/

|-CSXS/manifest.xml

|-index.html

|-.....

Thanks very much!

Seems to work for me as well! Thank you! The CEPHtmlEngine Helper (there are still multiple; the one with the highest percentage) now needs about 6-7% with some higher peaks as of now. Hope what ever you did will end in the next update.

I still can access the CC Libraries in PS, AI and InDesign after the hotfix.

Me not! Cannot find CC Libraries on window menu, nor on the left panels after this trick.

Also being driven insane with this CEPHtmlEngine issue. Opens and over runs the CPU on all CC apps including ID.

I believe this is the new libraries offering - which in itself is also a nightmare. Constantly attempting to save my artwork into a shared library. Unwieldy idea poorly executed.

Fans at full blast and CPU being cooked. Only solution is opening Activity Monitor and killing CEPHtmlEngine.

Please fix Adobe.

Hi JensSeidel‌otterstyle‌NE-Design‌,

Could you please show me the full command line parameter of the CEPHtmlEngine Helper taking 100+ CPU?

To do so, note down the PID (process ID) of the CEPHtmlEngine taking 100+ CPU in activity monitor, then open a terminal and type:

ps -ef|grep CEPHtmlEngine\ Helper|grep PID <-- replace PID with the actual PID

Thanks.

Thank you huid31332308 for asking!

The CPU load rises immediately after launching InDesign and stays between 80–100+ until I shut down the task or the application.

Here is the log (replaced my username with *USERNAME*):

Hi JensSeidel‌otterstyle‌NE-Design‌,

Did the CPU consumption issue happen immediately after you launch Adobe application, or after an extended period of use? Would you mind if I follow up with you to collect for information if possible?

Hi NE

I've just remove the damn ones by doing the following:

Finder > Applications > Photoshop

Click in show package contents

Search for CEPHtmlEngine

and you'll see these files:

CEPHtmlEngine

CEPHtmlEngine Helper

CEPHtmlEngine Helper EH

CEPHtmlEngine Helper NP

If you dare move them to trash !

All works fine now

By the way i don't use the CC app (cloud icon in the top menu bar) or extensions

Thanks abascalufe, something similar worked for me in After Effects.

/Contents/MacOS/CEPHtmlEngine

I just archived it and deleted the original. This restored AE CPU usage when idle to a sane <1%. This is a really nasty bug, on my MacBook Pro, AE was using pretty much max CPU when idle and instead of my normal 5-6 hour batter life, I was getting less than 1.5, basically making AE unusable when not plugged in to a power outlet (and even then it made it hot and loud and slowed the whole system).
