MacBook pro2012wi not connect to internet after uninstalling norto

Clean My Mac often causes more problems than it solves.

Try the steps here:

If your Mac isn't connecting to the internet over Wi-Fi – Apple Support (AU)

Uninstall Norton and CleanMyMac. Third party apps that claim to protect, clean, manage, boost performance, etc. are not needed and may cause problems. They use system resources while providing no benefit.

CleanMyMac has been demonstrated to be junk. It just guesses, looking for similar names, and often discards items that were needed by MacOS, and misses others that should have been removed.

You can't un-install an invasive program like Norton with anything other than the software-maker's un-installer. You may have to re-download the Installer to get the Un-Installer. Chasing down all the parts one at a time will take days.

Norton breaks into in your communications, so that it can be FIRST to scan for antique windows viruses that are not a threat to you.
