Big Sur 11.2.1 on Lenovo X260

Worked on this for quite a few days, had a problem that caused a very lengthy boot time of about 20 minutes, but finally figured that out (DSDT) and I've got a success! Installed 11.2 and upgraded in place to 11.2.1. Certainly doesn't perform like my M1 Air, but was a lot more fun.

CPU: Intel Core i7 6500U @ 2.8GHz

Bootloader: OpenCore 0.6.6

GPU: Intel HD graphics 520

RAM: 8GB DDR4-2133 Memory

Make and Model: Lenovo ThinkPad x260

Audio Codec: Realtek ALC3245

Ethernet Card: Intel I219-LM

Wifi/BT Card: Intel Dual-band AC8260

BIOS revision: 1.47 released Sept 2020

Trackpoint does not function, but this seems pretty common from what I've read. Or the SD card reader. Also still working to figure out why it doesn't wake from sleep, but otherwise everything else seems functional!
