I'm not particularly tech minded so MAMP has served me well for a good while. However I more recently decided to give Craft Nitro a try. I got everything (Multipass and Nitro) set up really easy. I then went to create a project and got the error PHP extension ext-zip * is missing. I've seen this before and worked around it guided by This post.
All good... craft installed. However, now i'm confused? Why did I need to install an older version of PHP on my host machine (OSX) when Nitro is supposedly a self contained 'box' with everything needed for a Craft install?
