The wordpress theme used on macintoshhowto.com is one that I designed to be simple and clutter free.
I have made it available for others to use, it’s called ‘Simply Zen’
This is inspired by the design philosophy embraced by Steve Jobs and used in Apple’s designs.
You can check it out at wordpress.org here https://wordpress.org/themes/simply-zen/
It’s a simple clean theme inspired by Apple’s design philosophy.
If you use it I’d love to hear your feedback.
