Some Mac users are reporting that X-Rite Device Service's XRDD process is using an exceedingly high amount of their CPU.We've seen an issue in Apple's Firewall Options cause an abnormally high CPU usage with XRDD. Please Try the following:
Go to System Preferences > Security & Privacy > and then choose the "Firewall" tab
Click the lock in the lower left corner. add your password, and click "Unlock".
Click on "Firewall Options..." and search the alphabetical list for "xrdd". If it is not there, add it by clicking the "+" sign. The xrdd resides at – Mac HD/Library/Application Support/X-Rite/Frameworks/XRiteDevice.framework/Versions/B/Resouces/xrdd.
If "xrdd" is listed in the Mac Firewall Options, remove it by single-clicking on xrdd and then click the "-" sign.
Lastly, re-add "xrdd" using the "+" sign and navigating to: Mac HD/Library/Application Support/X-Rite/Frameworks/XRiteDevice.framework/Versions/B/Resouces/xrdd.
