Hi all,

Got some pretty cool news. Found a ThinkPad T420 on eBay for $63 shipped. It is a complete rig, came with i5 2520M, 8GB RAM, 1600x900, 128GB Toshiba SSD, and 90W charger. Has HD3000 graphics. The issue was a corrupted Windows 7 install so looks like the guy didn't know how to fix or had time to deal with it.

also had this tape and stickers on the lid

And all cleaned up! It seems to be missing the little sticker for the LEDs on top of the case. Anyone know where I can nab that? Thanks.

Nice to see another T420 on High Sierra ;)

I have to wonder though, Vanilla or patched?

I have my T420 quad booting by running a token W7 (purely for just two programs!!), a flavour of Linux, High Sierra AND Mojave. I had my WWAN slot going begging (empty), so slapped in an mSata and that gave me 3 SSD drives. Topped it off with an i7 and 16GB, 1600mHz RAM. Tidy little machine spec and performance wise.

I may have a complete lid available soon as I have all but a complete rebuild kit ready for my T420. Just missing the base plastic/chassis shell.

So far my X201, X220, X240, T420, T430 and M73 all run OSX. I also have 3 Tower machines running OSX.

Still haven't quite found the necessary time nor tools to try and install OSX on my L412, although I am not so bothered about that.

I did a vanilla install, didn't use Multibeast/Unibeast at all. Does your T420 have the FHD mod?

Planning on the FHD, but ATM, no it does not.

Been too busy messing with other things to get near the T420, other than to use it.

Did you find the DSDT for the T420 per chance? Lots of install guides, only one really decent one out there and although not T420 specific, works just fine ;)

Are you getting/did you resolve the graphics glitching?

Not really actually, kind of a bummer
