An opinion - I believe, because Apple knew they would be using their own Silicon chip, they experimented/held off in the final 4ish years of Intel.
MacBook Pro experiments that ultimately failed:
Again, the 16" screen was a nice upgrade in 2019, but nothing else really changed that was for the better with the MacBook Pro lineup. I thought the Touch Bar was innovative when it was announced, but it's really only Touch ID that we got from it.
iMac did nothing....:
I think this has been talked about enough, but seriously, after the iMac got 4k/5k displays in 2014/2015, nothing changed. Peripherals just got slightly better every year.
Mac Mini also did nothing:
The best thing the Mac mini did was switch to space gray in 2018, add 10GB ethernet, and add some real power. While it was a nice upgrade, the price made it hard to justify the purchase over a laptop.
MacBook Air tried:
The MacBook Air got the significant upgrade with Touch ID and Retina display in 2018. While that was a great upgrade, the Air was such a weak machine. The iPad Pro was a better machine during this time frame. It didn't seem like it, but looking back (and if iOS was better) it was the better of the two pieces of hardware (which had Apple's chip).
All in all, the MacBook Air was the most "exciting" Mac from 2016 through 2019. All of the Macs look almost identical from 2012-2020 even! Now, every Mac with the M1 chip is considered a great purchase:
MacBook Pro experiments that ultimately failed:
- Butterfly Keyboard
- Touch Bar
- USB-C/Thunderbolt ports only
- Not an experiment, but not a lot of innovation

- MacBook Air - Great power, great battery, slim, full function row, no fans and affordable (best Mac you can buy right now, I think)
- MacBook Pro - Least exciting Mac of them all right now since it really isn't that different from the Air, but the next generation coming will make it the most exciting machine they have
- Mac Mini - The price for the base model doesn't get any better. I was blown away when I saw the Mini got cheaper and stronger with the M1 chip
- iMac - Obviously, not as powerful as everyone wants, but it is a beautiful machine that makes the 21.5" replacement a now viable option. The screen is big enough, is now 4.5k, adds Touch ID and looks amazing.
