cant connect MacBook Pro with hp wireless printer after installing mcafee. Rebooted modem, printer, used clean my mac app, restarted mac. Other devices ( iPad and iPhone connect and print). Uninstalled mcafee but icon still on top bar. Something is blocking my mac from the printer. In system requirements printer icon shows up but has a yellow small circle with a lightening strike in the middle. When I try to print doc, it says can't find printer. Thanks for any help or suggestions.
