@yuman I feel like the cutoff is whether you can still buy them new or lightly used. To take your retina MBP: you can't get that same model at the Apple Store, but you can walk in and buy a unibody MBP and it won't even look _that_ different to yours.
Whereas you can't buy the plastic-body MBP's any more, so they'd be the bleeding edge of retro, as it were.
@Two9A @yuman My personal line is the somewhat nebulous "meaningfully different".
Like a Core2 is old as heck, but it's not really meaningfully different to a modern machine, just slower, so it's not really interesting.
My 2011 MBP isn't really meaningfully different to the last x86 ones (other than its 17" form factor ruling ass in a way they can only dream of). It *is* different to the m1 though, so when x86 macs fall completely out of support that'll be enough for me, but for now, no.
how's that 2011 keeping up, is the AMD graphics still alive?
btw, here's my 2006 17: https://defcon.social/@yuman/116527734997036311
@yuman @Two9A Nah, that's how I ended up with it. There's a boot rom setting you can type in which blocks loading it, and then there's an article about removing a zero ohm resistor to cut power to it which significantly slashed heat and battery usage.
Works great on High Sierra with the iGPU though, lovely machine. Was a fine Linux box until the wifi started dropping out on it, almost certainly a driver issue.
it's way easier nowadays, had a buncha those. no need for soldering and tweaks, nvram GfxMode=4 kills the discrete graphics. not present in sysreport, wastes no power, no heat, etc.
had no issues with wifi on mine, they do need the proprietary broadcom drivers (broadcom-wl on fedora, wl on debian/ubuntu)
