Yes, it is.
Jesus H. Tapdancing Christ if Microsoft released a buggy OS nobody would be saying "Oh it's not Microsoft's fault, they can expect it to work on blah blah blah"
You're giving Apple a free pass because they are Apple. This is why us Apple users get snickered at by 92% of the population who don't use Macs. This is why we are not taken seriously. If Steve Jobs make a bowel movement, a million followers declare it divine and write blogs about it.
Think man, think.
Microsoft has to write an OS for thousands upon thousands of PC configurations.
Yet, you "blame" them. Hell, Apple makes an entire line of commercials pointing it out.
Apple supplies the software AND the hardware for their products. The expectation that it should work is infinitely higher for Apple.
Apple has it easy. They have to "test" their OS on 1,000 times fewer machines than Windows does.
Apple sells the machines that their OS runs on. And there are only a handful of models to choose from.
Given this, It could not be easier for Apple to test these updates on every machine configuration they have created for the last 10 years.
If they don't, it is their fault.
Damn, am I the only one that did not opt for the complimentary lobotomy with the purchase of my new Mac?
