CEPHtmlEngine slows Computer (Mac) and solution.

[NE-Design]

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.

tested on Macbook with 10.9.5 -  same issue.. new installation of OS new installation of CC - when application is "just" launched ok - but in moment choose (empty) file from default choices or open file CEPHtmlEngine starts to take majority of CPU and computers fan is on maximum almost all the time.

is it safe as some said to switch it those engines off manually from activity monitor on mac? or do I risk some corrupt of system or adobe or so?

if yes which one - they are in multiple instances while only single application is open...

It start to be hard use any CC application. I am used to listen computer while converting batch of RAW files or so but have no clue why single file opened in AI or PSD should rotate and overheat mac, that is on maximum with technical limits.. (16G RAM)... SSD disk.

please help. thanks,

martin

I just used Lr yesterday and it is practically unusable. Eats up all my RAM. I had AI open, but no files. I checked Task Manager and it showed both apps using 1.4GB each of memory. But I have 16GB. I'm not sure where the other Mem has gone, but CPU was soaring as soon as I launched Lr. Obviously Adobe has created a huge problem in their recent 2015 updates. I don't know what they've done, but they have royally screwed up something. I closed AI because computer only had about 54MB free of memory. I was getting nowhere. I turned off GPU performance too. I was thinking if I open PS to edit it's gonna crash my apps. After closing AI and doing a sudo purge in Terminal I was able to free up 5.6GB. Is Apple and Adobe working together to mess with my system or what?!? If this is how Adobe and OSX are going to work together, there's no hope for the future all the while charging my account every month and laughing to the bank.

äh, sorry, what exactly is wrong with you guys at adobe? you are selling software for professionals!

Two weeks ago i have spent six hours with update-troubles, now i have to take care of the CEPHtmlEngine ...

you are stealing my time with your products!

[boldusain]

Dear Adobe

This issue seems to be around for quite a while. Why isn't there still any update to make things run smoothly?

I always have to kill all those task in the activity monitor manually. Very very annoying!

[hambergk]

Yes I agree this issue needs to be addressed right away! Please Adobe do something about it.

So I just put Creative Cloud > After Effects on my brand new 5K iMac today and ran into the same issue, eating up CPU usage in the activity monitor... I had to go searching for this fix (btw thanks for posting a solution Huid31332308), and then fix it.

In the process, while looking through my installed applications folder, I happened to discover that Creative Cloud also installed (without my consent!) Adobe Character Animator, and Adobe Media Encoder CC 2015... which amounts to an extra 3GB of disk space on my computer... WTF Adobe!?! I have absolutely no need for either of those apps (I move ProRes Master files in & out of After Effects from FCPX)... and now I have to remove them too, when I didn't even ask for them in the first place! Also, when I quit both After Effects and Creative Cloud from the menu bar, the CEPHtmlEngine issue is gone, but there are still about a dozen other miscellaneous Adobe-related processes floating around in the Activity Monitor which is annoying... I know it's eating up minimal system resources, but I don't want any of your miscellaneous software strewn across my computer using any of my system resources when I close everything!

Seriously Adobe... it's all this kinda stuff that makes me cringe anytime I install your software on a brand new machine. I want 1 of your apps running on my machine, but I end up feeling like my computer's infected with a multitude of leaches. Very disappointed.

AWESOME!!! BIG THANK to huid31332308

System: McBook Pro 15' i7 Build 2016

OS: El Captian 10.11.3

Software: Adobe CC

Problem: Extreme fan speed, abnormal loudness and strong overheating by working with Photoshop, InDesign and Illustrator.
My laptop would be destroyed if I had worked a long time with it problem.

Solution: CEPHtmlEngine slows Computer (Mac) and solution.

Perfect, thanks for the Support!

I am having the same problem.

For the past two days, whenever I open and use Adobe Indesign, my CPU usage increase over 100% making the exhaust temperature up to 80 degrees Celsius and above which turns on the fan.

The fan does not stop running till i quite Indesign. Then it goes back to normal.

It is really annoying that whenever you start an application the fan starts running and the exhaust temperature increases.

This is something new as it never happened before so is there a way to stop this?

PS: I am using El Capitan

version 10.11.3

[ArtyomM]

Same here with Photoshop CC in El Capitan 10.11.3. When we can see the fix?

[davidkanderson]

If you are looking for the correct folder for After Effects on Macintosh, the path is:

Applications/Adobe After Effects CC 2015/Adobe After Effects CC 2015/Contents/Resources/Libraries/

Just replace the contents of that folder with the contents of the DL 2.2.4 folder.

It worked thank you!

[pt-tiagosantos]

It worked. thanks.

I am running an older mac (late 2009) with an intel core duo and 8 gb ram and have found that the computer was running slowly when adobe applications were running. I went into the activity monitor and found three instances of the CEPHtmlEngine and five instances of CEPHtmlEngine Helpers. I forced quit the engines and so far have not had another problem. Not to mention my CPU usage went from 80% to 8% the moment I shutdown the engine.

This is a screen shot of my CPU usage while running the engines and the drop in usage when I force quit them.

finally with the last update of InDesign CEPHtmlEngine problems are over.

online Library still operating.

[Drawingbreath]

The posted fix shown in the original post does alleviate some of the pressure. I just hope that any official fix manages to get rid of a background process that's so demanding and memory hungry. With all the helpers and engines running with just Creative Cloud, Photoshop and Illustrator running they are still the highest process and CPU users for a background process. A constant 10% CPU combined and a 1GB of RAM being eaten up.

I sure would like to know what these "helpers" are supposed to be helping, other than shortening the life of my computer.

[Cristian Contreras]

this is the official solution? no date ... do not know if this was applied in the last updates yesterday.

Adobe is so full of crap! Why am I (a paying end user), having to do upload software developer patches to their overpriced software. There are better fixes with open source. I have updated to the latest with PS and now I can't access my libraries. They haven't fixed anything, but instead created another problem. I don't know where Adobe get's these idiot developers, but I'm pretty sick and tire of seeing money come out of my account every month to pay for software that's this buggy. At least when Adobe was making boxed retail versions they had to mostly debug it. Now they update it every six months and introduce and new issue, which takes (if you're lucky) another six months to get a fix, but nevertheless, introducing a whole other problem. VERY frustrated and angry with Adobe and their lack of support or care.

[davidg2020]

Have to agree with you... Adobe seems to have gone down the toilet.

And they've just sent me an email to say the subscription price will be increasing later in the year!

More money for poorer products. I guess that's what happens when you fairly much have a monopoly situation.

[mattk79]

What kind of email? I have not received anything about an increase. Please relay this info. Sick of Adobe!!

"What kind of email? I have not received anything about an increase. Please relay this info. Sick of Adobe!!"

I received this from Adobe on March 29...

My current subscription is around $85 (for Creative Cloud and Adobe Stock combined).

[davidg2020]

I'm not sure why I blurred my name when it's at the top of the post! Doh!!!

[Steve Werner]

It seems to be a price increase for the Australia market for the reasons listed in the letter. It's not an increase for everyone.

[davidg2020]

I realise that. Its still a price increase though - for me and all other Australian users.

And the Oz dollar has gained on the US dollar of late as well... it should be going down - not up!

[mattk79]

Oh I see!

Thanks so much for sharing the solution. I'm on a MacBook Pro w/Mavericks (I know, Mavericks -- but I don't want to upgrade systems right now with all of these issues already causing massive problems). Went through the entire process of saving Library file backups as suggested in PS, Illustrator and InDesign and downloading DL224 and replacing with new files.

Unfortunately this worked for one session, then, while fans haven't gone crazy, the CPU is being eaten up again, beachball is spinning and Illustrator just crashed trying to sync typekit, which is turned off in my CC preferences. Multiple copies of CEPHtmlEngine and Helper and goodness knows how many AdobeCRDaemon files in Activity Monitor.

At this point I'm not going to keep trying a solution that won't stick, and am killing apps in Activity Monitor again.

I just want to be sure this is the last known solution before Adobe issues some other "fix"? Do you happen to know? Thanks again.
