I've been a CCleaner user for 6 years and a Mac user for 4, have 2 macs (one Snow Leopard, one mavericks) both running parallels with windows 7 and 8. I honestly use Onyx for more complete maintenance solutions but love the speed and simplicity of CCleaner. I would be happy to offer my services, are you just wanting us to skim through the forums and offer insight/resolution on mac specific questions/issues?
