Upon upgrading to Yosemite two years ago, Safari stopped working completely on two out of my three Macs (one brand new, bought just months before) with the third one intermittently working. Apple's software quality is really a joke and Safari is the new IE in many ways. Its support for standards is behind every other major browser and it hardly ever opens without crashing. Why would I use such shitty software when I'm not forced to? I avoid iTunes for the exact same reasons except when Apple forces me to use it to put music on their devices. The core OS X system is generally solid (other than the myriad of wireless issues Apple can't seem to ever solve) but the apps that come with it range from substandard to total shit quality.
