I’m a Mac user/developer since Day 1 experiencing Apple’s ups and downs during the classic Systems years. I wrote extensions for MacTCP, CyberDog and AOCE. I worked through CPUs from Motorola, IBM, Intel and now Apple’s own Silicon. I retired from the University of Michigan in 2009 and as an independent developer got my first iPhone app in the App Store a couple of year later. I’m still a keen observer of the Apple ecosystem.
