2010 MacBook Pro. On its last legs, but standing by nonetheless.
Why? (I mean "last legs") Dropped it from an airplane? After a new battery, (waitlist) new 802.11ac card, bluetooth 5, raid 0 ssds (NVme in the plans for the near future vs raid) what more can anyone want?
Whatever is broken, in these Macs, it is easily replaced and, for now, there are plenty of parts.
After this, the aluminum gets thiner and the whole machine is less rigid just as the edges get sharper and keyboards get weird. I wouldn't mind thunderbolt 3 but I plan on using an wifi+NAS+VPN for storage and most of what I do is text or PDF so graphics support on the laptop (cMP graphics, that is another issue) isn't all that important. That being said, for a laptop, even though weight has become soooo important for soooo many, durability is tops. Magsafe doesn't always release perfectly even when it came from Apple and a dog or a kid can turn that 2020, paper --or rather, aluminum foil-- thin "pro" into expensive mush. The 2010 is solid (a different kind of "solid" more bakelite 70's phone than ABS 80's) enough to crack a head and get right back to work; the 2012's that I've seen just don't look as solid inside. I admit that with calipers, the thickness of the aluminum structure could be the same but to my eyes?...
All that matters because I am never going back to any WinTel (at least, not past Windows 2000 + Svr4 Unix add-on) and
I hope that neither will anyone else (maybe, then, Microsoft will fix the foundation before the house collapses) to an OS that is so non secure and buggy that it hasn't been news for a long time - and no one is surprised that rather than tackling the problems Microsoft has been dragging along for decades, Microsoft updates the eye candy or clouds the mind with non issues like "we are going to __________" (force updating, close off the registry, hide the control panel, etc... take your pick) rather than working on a functional client registry (if we must, if it is so "good" a solution then why is there a config.sys and autoexec.bat still?) or making a choice and sticking with it (Powershell vs lame linux) rather than tying something on with sheet metal and bailing wire just so they can say "me too!" Sure, at some point, Apple will drop support beyond anyone's wizarding ability --and DosDude has been as powerful as Dumbledore at his best-- and I will move on to something secure and a half like OpenBSD.
I will fight to keep MacOS (seems like they are bent on erasing Steve Jobs from Apple, eh?) and listen to AppleMusic while I type but like a curmudgeon of old, I AM KEEPING MY BAKELITE PHONE!
If someone at Apple had any brains he would make sure that security was airtight all the way back to Snow Leopard so that any breach was, clearly and demonstrably, someone else's fault. Apple is well on its way to becoming IBM and we are living just before they released the MCA architecture. The licensing was so baroque and expensive that ISA architecture won the day and IBM...
