Kernel Panics are Oh So easy to Provoke — Remove an SD Card

If you’re not happy with only being able to crash a highly protected modern operating system in Photoshop, this one is for you.

It isn’t new to macOS Big Sur; it has happened regularly before. It happens fairly often to me, perhaps in 1 in 6 times:

  1. Unmount a volume for a camera card (SD card). It might have to be in a dock or external reader (not sure since the Mac Pro has no built-in SD card reader).
  2. Remove the card.

A crash of macOS follows.

Good work Apple! Now get to work on those new emoticons and stick one in the screen of death just to make things better.

Just read your experience with the latest Apple core rot. To be honest, I'm glad I don't have to rely on the latest OSX on my workhorses. I always stay 2 versions behind and watch the "dernier cri" of Apple stupidity unfold on stage.

But what I see and hear from my customers and friends about failures and problems with the latest OSX since the glory days of Snow Leopard to this day leaves me sitting speechless and stunned. It seems to be a mixture of ignorance, arrogance, helplessness and kamikaze.

Although I am a German, I know what it means when something "goes down south". Well, so what do we expect from something that is even called "Big Sur" then ?!? ;-)

And about the pointless configuration bars: Let's remember the old saying of WW2 soldiers, when something is fucked up beyond all recognition: F.u.b.a.r. That's the new Fubar's! hey! 

Apple management is looking more and more to me as if the "Brain Bug" from Starship Troopers paid them a visit....

MPG: technology is now so advanced, that’s hard to imagine any elegant designs happening any more. Features (most of which go unused) result in more and more complexity, which results in more and more bugs. And so the steady drumbeat of weekly software updates, which fix half the bugs and replace them with another new crop.

Compare that to the just introduced Sony A1 digital camera. A technological tour de force, it’s a tool that works for a purpose incredibly well. And it never bothers me with updates or demands to login. And it never crashes.

As someone who has used technology all my life, more and more I am turned off by most technology—so much of it makes life more of a hassle, not a convenience.
