I have tried three times to load the new desktop update on my Mac running OS X El Capitan 10.11.1, I keep getting the following error:
The application cannot be installed due to a certificate problem. The certificate does not match the installed application certificate, does not support application upgrades, or is invalid. Please contact the application author.
any ideas?
