Sigh. You can't blame hardware when it's an as-new MBPr. Every Mac lover seems to blame it on something else when it is just a crappy OS that is the root cause.

Sigh. You can't blame hardware when it's an as-new MBPr. Every Mac lover seems to blame it on something else when it is just a crappy OS that is the root cause. On Windows it is extremely rare - maybe once a year, but you'd have to be a power user for sure. On Mac, it is usually a weekly occurrence. Hell, I had it happen last night in fact just by trying to mount a DMG file (a freshly downloaded TeamViewer DMG if you must know). It decided to go to the beach instead. After a full reboot it finally let me mount it. It really is a joke of an OS. If you're not familiar with Windows IO then why try to cobble together a response? It is true that the Windows kernel does not support anything but asynchronous IO. It simply does not support it. Yes, user-mode land implements synchronous wrappers as a convenience for lazy developers or to aid in porting software from other lesser platforms.
