I originally sent this to a good friend who, like me, is a Mac user.  Then I sent this to Tim Cook at Apple.  And I have decided to post it here as well…  

If you are a Mac user, you should definitely read the linked commentary.

Great commentary by a long-time Mac software developer:

Additional thoughts:
A couple weeks ago, when the last macOS software update left my computer (and many, many others) unbootable and I wasn’t sure at first if something major had died hardware-wise, as I pondered possible replacement scenarios I came to the conclusion that my machine dying might be a long-term blessing by almost forcing me to ditch Apple hardware.  I could have gone the Hackintosh route (using off-the-shelf hardware) or could have just switched to Linux (with a huge range of options for hardware).  I know such a switch is not the right thing for everyone, I don’t need to use Adobe CC for instance, but I feel Apple is so focused on squeezing money out of music streaming and watch sales, they have forgotten how they got to where they are.  I no longer feel any loyalty to them as I see they have little if any interest in their computer customers.
I love my Mac Pro, though it has a limitation or two, and I am glad it is working well again.  But I have it set up to dual-boot with Ubuntu Linux, keep that software up to date daily, and continue to explore the software that is available for that platform.  If something happens, I will be ready to walk away for good.
