I always enjoy the Apple keynote speeches. The one everyone always remembers is where Steve Jobs introduces the first iPhone, but I feel this one may also go down in history.
The best thing about the Mac operating system is that is was always designed to be portable, ie could be recompiled to run on different architecture.
This has enabled the Mac to move from one system architecture to another.
I started with a PowerMac, a lovely little 12 inch laptop for my portable photography needs. So I have lived with the transition from IBM to intel and the improvements that brought.
When Apple released the iPhone it was with an off the shelf ARM processor. Then over the years Apple has been buying up small ARM design companies, then became a full ARM licensee to enable them to start producing there own ARM designs. This has seen the iPhone and the iPad gradually pull away from the others in respect to battery performance, cpu performance and gpu performance. For nearly two years now there have been rumours that Apple would transition their laptops away from Intel to their own silicon but I have always thought the idea ridiculous.
Well I was wrong. I can certainly see the draw of something like a ARM powered MacBook Air. You could increase performance a little and greatly increase battery life, it would be the ultimate small laptop.
For the higher end laptops like what I am typing this article on, one I picked for its Adobe Photoshop and Lightroom Classic performance, I am not sure if ARM can match what Intel can do. The other issue is will Adobe port over Lightroom Classic or use this to force us to move to the new Lightroom. For photographers like me with large libraries the new version still does not quite cut it.
Its going to be an interesting couple of years a head of us.
