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 am also having a similar issue. using a MacBook Air. I noticed that the issue is pretty recent but syncing my files seems to take an excessive amount of memory. In the activity monitor, “core sync” seems to regularly spike up to 40+ GB of memory Which at best slows my computer to a crawl. I’ve tried calling someone at Adobe about this but they don’t have an option in their phone directory for the desktop client.
my computer is currently frozen
I'm shocked that there is no solution to this problem after 4 years, as I am having the exact same issue. Core Sync. On an iMac. Latest Mojave, but was happening before Mojave.
The problem is compounded because I'm now on satellite internet, which allows me less than a Gigabyte a day of data use before they cut my speeds to make it pretty unusable.
The scenario is it looks like everything's fine. I'm using a normal amount of data. I come back in less than an hour and Core Sync is running with nearly 200mb data spent on the process. I have followed all the other suggestions here -- syncing off, Creative Cloud app is closed. My work flow is to open Creative Cloud in the early morning hours so that when data is cheaper I can run these processes, but they run anyway. Creative Cloud should not be running processes that hog data when the app is closed.
I really love Creative Cloud and use some of the applications for work, but I can't afford the data it is hogging.
I have not uninstalled then reinstalled Creative Cloud, since others have not had a positive response from this. And the amount of data required to do such a thing makes it a last resort. I'd be using up data for days. Why can't you just allow us to control when Creative Cloud processes happen?
This is an issue which should be resolved by updating to the latest version of the Creative Cloud app. If you have the latest version, I'd suggest uninstalling and reinstalling the Creative Cloud app to test if the behavior persists.

Thanks for your reply, Dave. Should this solve the problem, even if I’m already running the latest version? Re-downloading the entire Creative Cloud app plus the individual apps will take a tremendous amount of data that I’m limited on. What’s the likelihood this will work?
Okay, Dave... I went ahead and did the reinstall. So far, the Adobe processes are still running in the background, but at a much lower usage. It will take a week or so to monitor this and make sure that it doesn't return, but I'll update either way.
Thanks for your help.
Today I contacted Adobe Support, they accessed my computer remotely just to open the Creative Cloud desktop app and check the memory usage. Of course it was performing well and using low resources at that moment. This problem happens RANDOMLY, even when I start my computer and not using any Adobe app, not even the CC desktop app which I have constantly closed and the syncing paused.
Adobe, we really need a solution for this. After 5 years of this issue being reported here, many users are facing the same problem with the Core Sync process consuming almost all CPU and memory...
Yes, happening to me regularly and it is September 2019 five years after your post! Nothing seems to have changed. I have to reboot each time to speed things up. Only ever happens when my online ID CC is in use and I leave it for half hour unattended. Never happens for anything else!
Core Synch is preventing my completely fresh build PC from shutting down correctly. What is this abomination of background software running?? Pls fix this or I consider fixing my abo!
Hi, join the crowd, we all suffer the same issue. It is a known problem of using ID CC which has not been fixed in years. It seems to mostly happen when you leave ID CC open and unattended for a period of time, then when you come back to it, it is running so much in the background it takes 10 minutes just to click a few keys to shut the computer down and reboot it - the only way to clear it!!! Of course you could let it run and choke the system for a bout three hours befor it stops, and get no work done. A huge productivity issue. I've wasted hours upon hours the past weeks alone, sitting watching the slow response of working on my PC when ID CC is open, and it is nothing to do with the PC being used...........................
Same issue. Have Adobe CC on 3 machines (2 personal and 1 work). The personal machines have CC so I can use Lightroom & Photoshop and the work machine has CC so I can use Adobe Acrobat. When I go to shut them down I get the same error. Adobe FIX THIS!!!
