My M1max laptop I bought in 2021, has served me well.  It still has plenty of life left in it, but I've graduated to the new M5max 14 inch.

I cleaned up the body, wiped the disk and installed a fresh copy of Tahoe 26.3.1 -- you just need to complete the setup.  Comes in original box, and I replaced the magsafe cable with a new one, as seen in the photo.
