When I connect my iPhone XS to my MacBook (Big Sur 11.1) and open the Finder tab for the iPhone I am asked whether the Computer should trust this phone. When I click the button "Trust" I get the error:
"Trust request error (-402,653,181)"
After updating the devices Mac and iPhone and still getting this error.
Finally I found the issue, my McAfee blocking me.
sudo /usr/local/McAfee/AntiMalware/VSControl stopoas
Once the McAfee is disabled. you can sync your iPhone to the Mac/Xcode.
