Question

Core Sync Process Choking Systems

I have Adobe CC installed on an older MacBook Pro running Lion and an iMac running Mavericks. Ever since the last CC update, my processors have been maxed out and the Finder locks up (usually after first booting up). The activity monitor shows "Core Sync" hogging most of the CPU - anywhere between 75-99%. Once I quit the process, the CPU returns to normal. I also have Adobe CC installed on a PC running Windows 7, which produces similar CPU usage. I am now in the habit of force quitting Core Sync first thing when I boot up and when Core Sync switches back on, I'm sometimes forced to just shut down CC altogether. This should not be.

Is anyone else experiencing this problem? Adobe?

I have this problem today in Windows 7 (64bit) with 13% of CPU constantly in use.

I ended the process in the Task Manager and immediately a Flash Update prompt was presented to me, which then errored out. A retry resumed the update okay.

Will keep an eye on this...

I have the same issue, Core Sync daemon restarts even though file sync is deselected.Result is Finder is sluggish and cpu real slow. Please Adobe we dont want or need your really bad sync stuff. I am going to change permission to 000 so it can't start again as soon as I find where Adobe put it.

I'm still seeing these issues, just updated CC 8 hours ago. 100% CPU usage and eventually causes Finder to become extremely sluggish, this is on a new MacBook Pro.

I also have no Files to sync. Today I had 100.2 % CPU for the Core Sync. It is not possible to work with this problem! I have no Idea whatfore this app needs the cpu in that way. Should be a small background job.

I found a solution to my sync problem in iMac

In the Library/Preferences/com.adobe.accmac.plist Rename or delete this file.

I got instant response and the sync files and fonts works. But there is no green checkmark in the folder for synced files, but I can live with that.

Best Regards

Seeing the same issue. I'm not typically signed out of Adobe Creative Cloud, but I always quit the menu bar Creative Cloud app because it serves no purpose except for updating the apps.

I also don't sync anything with Creative Cloud, but am seeing the same thing. Finder + Core Sync are using near 100% of CPU and I have to Force quit Core Sync and Adobe Desktop Client and Finder to get it to work again, mulitple times a day.

Count me in as someone who is seeing this issue.

The Finder is dog slow and I look at activity monitor and CoreSync is pushing 100% CPU utilization.

One important thing to note, I don't sync anything with Creative Cloud. I keep no resources in the cloud. Everything is local. I am not running Photoshop or Lightroom yet CoreSync is chugging away. After I kill CoreSync the Finder becomes responsive again.

12 core 3GHz Mac Pro.

Will we know when and if this is fixed?

The Creative Cloud app was just auto-updated, but I can't seem to find a list of what was involved with the update. Is there a bug list, feature improvement list for Creative Cloud core components and the Creative Cloud App?

I appreciate that work is being done, but I would also like to know what's broken and what's been fixed so that I can keep my computers running and get my job done.

thank you,

I noticed this also. Running latest version on osx yosemite

Whenever I have the Finder app in focus, it would be extremely sluggish. (and this is a fast mac w plenty of ram too).

I narrowed down the issue hopefully...See if anyone else can duplicate this:

When I am signed OUT of Adobe creative cloud in the adobe application manager, core sync spikes the CPU to 30-40% (or more) when I bring the finder into focus, and it's very sluggish to do anything with Finder.

When I am signed IN, then there are no lag issues at all.

It's like Core Sync will just keep attempting to run even though it's failing to do its job because you're not signed in.

Just wanted to add that after quitting and leaving Creative Cloud app off, the 2013 Mac Pro with Yosemite is running much smoother without a slowing down effect.

After trying several configurations of turning on and off various running apps, it appears Creative Cloud may be the issue.

There was no sync or any type of cloud syncing turned on with the Creative Cloud app except for several fonts and keeping apps up to date. Result was occasionally it would use 100% of the CPU with Core Sync slowing everything down.

Fonts continue to work fine without the app.

Just wanted to add:

- if I have Creative Cloud app open, Core Sync will initially be zero cpu

- if I scroll the sidebar of a finder window or scroll quickly in finder window lists/column view Core Sync will jump to at least 25% cpu

- once I stop, Core Sync goes back to zero

- if I try to move lots of files, Core Sync begins to use cpu

- is this intentional?

The Core Sync is using quite a bit of resources, and I had already quit Creative Cloud app in the menu bar.

What is Core Sync and why do I need it?

I have quit the CC application, Adobe Services and Core Sync. I don't use File Sync, Behance, Font Sync. And, my system is working better. The sluggishness that I was experiencing seems to be related to the latest update and the CPU usage.

With these turned off it works fine. What will I be missing with them disabled?

I have this problem with a Windows 7 machine and a fresh install and not running the Creative Cloud app. I kill the Coresync app to get control of my machine. Will there really be a solution? I also have a problem on my personal machine with the background processes taking so many I/O reads that it almost locks up the machine and makes disk light go solid. Support says I could uninstall my programs and pay over $50 a month for the idea of some software! Is there a solution to this? I tried to start a thread on the I/O issue and was met with silence here. I had an exhausting chat with support about how to free the machine up to run when I wanted to do other things.

Hi,

Some people are likely to see intensive CPU and disk use while Creative Cloud is syncing all of your assets to or from the cloud to a new fresh system, this shouldn't last long however.

Nope...I'm not syncing assets and it lasts until I kill processes. I don''t have any assets in the cloud and syncing is off.

I am suffering the same problem on Macbook Air mid 213. 

even when i tried reducing the download bandwidth to 25% it seams to have no effect.  If core sync starts it consumes the whole cpu...

  • Core Sync taking up 100% when syncing files
  • causing cpu fan to run at full draining battery at a very high rate
  • once sync has started the cpu does not decrease even when sync is paused
    • it has to be force quit as a process to stop

I have now disabled syncing of files and now use dropbox as an alternative. Dropbox works very well so i know its a not a fault with my machine.  Please can you sort this as its now June and the problem is ongoing

cheers

W.

Hi Waynedge,

Thank you for raising this issue on the forums, we are working hard on performance improvements for Creative Cloud, these improvements will be included in future releases.

A work around for now is to let Creative Cloud work on syncing your data/assets until the full sync job is completed, I understand this may take some time and max out your CPU(s) depending on how many assets you have, after sync is finished you shouldn't see this kind off issue again unless you uninstall Creative Cloud and re install).

I hope this helps.

Thanks

Warner

Will Adobe buy me a replacement if my MacBook Air dies of heat stroke?

CPU is boiling (98° C) since 2 hours again.
