Apple has never, so far as I am aware, deliberately targeted developers as a primary audience of a laptop computer.
Apple's laptops became popular because they ran an operating system that was Unix under the hood, with a nice UI and good set of non-developer applications, which made them good as machines a developer could use for work and for non-work (Linux on the desktop being not so great at the second part of that). Apple has certainly been happy to make money from developers buying laptops as a result of this, but has consistently ignored the expressed wishes and desires of developers when updating its laptop lines, meaning Apple was popular in spite of Apple's indifference, rather than because Apple lovingly catered to this audience.
In other words: if you were looking for an executive to run around the stage screaming "DEVELOPERS! DEVELOPERS! DEVELOPERS!", I think that was probably some other company, and they got ridiculed for it...
Here's an article about when they stopped targeting science.
