In what universe? Because that isn't the case in this one. While some Macs do fail, as is unavoidable in consumer electronics, far and away more Macs last longer working correctly, mainly because they aren't crates of the worst cut-rate parts to be had out of the Guangzhou foundries.
Only Apple would have exact data of failing Mac numbers.
But in my local Apple service provider, lots of visitors claim their warranty everytime I visit them.
My personal iMac has 2 display + 1 HDD replacements just within the first year.
My iPhone 4S has this dodgy home button and creaking backplate after 6 months.
My 4 years old Macbook had 2 blue lines on the screen so I had to sell it for cheap.
So far I never had an Apple product with ZERO problems during ownership period. The one that doesn't need to go back to Apple Store, ever.
I had Samsung CRT monitor, plasticky and fugly as usual .. but it had zero repairs, and picture looks just as the day I bought it for 10 years. I never had that with gorgeous looking Apple displays.
Hard lesson learned, I always sell my Mac computers just before AppleCare runs out. Because it will always be expensive repairs once I'm out of Apple's warranty.
And you understand by now that all Apple stuff are Made in China in a shoddy Foxconn factory by a low-paid workers. Just as with 99% of all consumer electronics.
The reason I still stand up with some Apple products are nice design and build quality (read: pretty looks) and a decent warranty service.
Ironically enough, it's the pretty looks that often result in bad calls.
