I sympathize with many of the recent comments here—this and other recent quality issues are testing my already thinning patience with Apple. Every macOS upgrade brings useful additions and performance upgrades but also an array of new and sometimes debilitating performance problems and bugs. Those of us who rely on Apple products for our livelihoods are hit hardest by the sloppy quality control.
Quality control and customer support at Apple are not the same as they were just a few years ago. Every time I've had a hardware or software problem with a new or almost-new Mac recently, I have to go round and round with the Genius Bar people to find a solution (or convince them that there is a problem). Apple has become very stingy with the warranty/AppleCare repairs and replacements in recent years, and they're increasingly tightly scheduled at the stores, making it hard to get timely support. My suspicion is that Tim Cook's fanatical focus on efficiency, combined with a near-vacuum of product enthusiasts at the top, has led to major corner-cutting.
This is a company that used to be driven from within by strong, visionary leadership; it's now a behemoth driven increasingly from outside, by the need to meet meet quarterly analyst expectations. Forums like this could be very useful to Apple, letting them know that they have a problem with quality and customer support that they need to fix before they squander more of their once-formidable brand loyalty.
I sympathize with people's desire here to switch to other ecosystems, but which ones? Microsoft products are just as glitch-infested, if not worse. The other hardware companies (HP, Dell, etc.) make horrifyingly shoddy devices. Google netbooks are underpowered and no replacement for a MBP. Correct me if I'm wrong.
