I have repeat problem with McaAfee product in iMac with failed update. Did uninstall and reinstall new McAfee product a few months ago but problem has now recurred. McAfee provided to me as part of ATT uverse service for home. I got a McAfee rep to help me last time and cant remeber how to do this. Can you send me instruction?
iMac (21.5-inch, Mid 2011) is my version. i have had repeated failures of updates and my iMac has been running very slow since installing. a few times after i installed, it said that the extensions for site advisor were not supported by Mac OS
