2019 16" MBP - Adobe CC using 100% CPU making fans rev at max speed?

[ThisBougieLife]

Anyone else having this problem?

Ever since I upgraded to Big Sur, I have this issue where something called Adobe "CCX Process" and "CCLibrary" runs in the background and regularly uses 97%-100% CPU load and causes the fans to rev at max speed. The only way to stop it is to "Force Quit" the process otherwise it will continue as long as the computer is on.

This is really disappointing because I regularly use Photoshop and Lightroom. Obviously this is more of an Adobe problem, but I'd thought I'd ask around to find out if anyone else is having this issue.

Yeah this is happening every time I start up my computer now. So this morning I uninstalled Adobe CC. I haven't unsubscribed because I have a PC and I can use Photoshop and Lightroom on that for now.

Hope a fix comes soon.

Hi @ThisBougieLife,

Sorry for the late reply.

I also noticed this on cMP5,1 but I didn't have as much CPU load.
I also noticed that after using one or more Adobe products and killing the following processes AdobeIPCBroker, CCXProcess and CCLibrary, everything went back to normal.

After using Photoshop, the 3 processes are started, after using the other products only AdobeIPCBroker and CCXProcess are started but not CCLibrary.

But I also noticed that if you kill the AdobeIPCBroker process first, it restarts immediately, so you have to kill CCXProcess and CCLibrary before AdobeIPCBroker.

So I decided to write a small utility in AppleScript that checks if AdobeIPCBroker is started and then looks for the number of each process and kills them in the order mentioned above.
When I'm done with one or more Adobe products I make sure they are closed and I run my utility.

The first time, before using my tool (in order not to have an error message) it is necessary to open Terminal and run the command:

sudo xattr -rd com.apple.quarantine

then drag from the Finder "CCX & CCL & IPCB Killer.app", validate with the Enter key and inform the Administrator password of your session. (don't forget to put a space at the end of the command before dragging)

Like on this example:

sudo xattr -rd com.apple.quarantine /PATH_TO_THE_APP/CCX\ \&\ CCL\ \&\ IPCB\ Killer.app
