Apple Quality Control

Compared to Microsoft, Apple has serious quality control problems with their software/system updates. For many of the updates that they release, there are significant problems with them. One firmware upgrade caused my computer to become unbootable, requiring me to hold down a combination of keys on my keyboard to make their computer useful again, if Apple Support knew that trick (which they didn't, they made me send my computer in for service). One of the updates caused my computer's speakers to make popping noises (it wasn't just my computer's speakers, other people had the problem too). Apple resolved this problem with another update. Another update caused people's optical drives to stop working. Apple removed that update. Yet another update causes applications that were not specifically built for Intel-based processors (Rosetta applications) to stop working. I could sympathize with Apple (somewhat) if these were caused by obscure applications. But they're not. Many problems occurred directly with Apple's hardware. (The first three problems I've listed). While Apple may have come out with with Intel-native applications, there are certain applications -- for example, this obscure application called Microsoft Word -- that run on Rosetta. I'd like to give Apple the benefit of the doubt, but it is now at the point where if I see an update, I wait a week for Apple to iron out the bugs before I install it. For Microsoft updates, on the other hand, I install them instantly on my PC and, knock wood, have not had a problem with them.
Microsoft does not control the hardware that its updates are installed on, and yet still manages to have very few serious problems with their updates. Apple should improve.
