lmasanti said:One point in the PowerPC to x86 transition that you forgot to mention is that the NeXT OS was already running in x86 hardware.
The Motorola to PowerPC was a ‘new writing.’
This is the same situation in x86 to ARM on Macs: the OS is already written-at-large in iOS.
This makes this transition more similar to the 2005 transition that to the 1990.
Also, the port of Classic Mac OS from Motorola to PPC largely continued to use emulated, not new, code. From 94 thru the early 2000s, Macs dragged a lot of 68k code along that wasn't entirely let go until the OS X transition to x86!
dinoone said:ARM recent vulnerabilities (incl. Checkm8, Spectre and Meltdown) surfacing in past Apple silicon efforts, including the currently pervasive T2, are concerning indeed.Hope Apple is finally reacting to such Achilles’ heel in its Apple Silicon strategy. Which, if appropriately handled, could turn into a strategic advantage on competing mainstream silicon.
None of this is "concerning indeed."
The T2 chip includes Apple’s hardware accelerated video encoder for video. If Netflix were to “just use Chrome” it could perhaps “do” 4K video in software but it would be lower quality and cause a major implosion of battery life while the fans ran at full tilt as you’re trying to watch Netflix (and would force users to run Chrome.Capture a 4K video on your iOS device and then try to play that on a pre-T2 Mac and it will be readily obvious.As we have been noting for some time, T2 was the first step towards Apple Silicon.

It sports the same Bluetooth 5.0 and 802.11ac WiFi, and can attach to an SSD for storage using USB-C.
This jumped out at me. The 2020 iPad Pro does not have 802.11ac WiFi but instead the latest standard 802.11ax WiFi 6. It is weird that this Developer Transition Kit doesn't support WiFi 6 when clearly Apple has the silicon to support it. It must be a driver problem. They have an iOS driver for whatever chipset they are using but not a macOS 11 driver.
Obviously, this isn't a serious lack on the DTK. I just found it interesting.
