Back in 2012 I purchased a refurbished MacBook Pro 17″ Unibody. (Refurbished due to the GPU having failed already but that’s another story)

This Macbook’s latest Apple supported OS was High Sierra. So some years ago already this machine was being passed by and less capable of running latest apps like Daylite and PDF Expert.

Along came dosdude1 with his sensational patcher for installing Catalina on an unsupported Mac. This allowed the MBP to continue being of useful service until last year when again Daylite and PDF Expert had passed it by.

So I bit the bullet this weekend and decided to give my MBP 17 an OpenCore Legacy Patcher – Sonoma xmas upgrade.

All I can say is that the entire process is so slick that it motivated me to write this.

If you have an old Mac and want to install a later or latest OS then check out; https://dortania.github.io/OpenCore-Legacy-Patcher/

Well worth a look.

Thanks to everyone at OpenCore.
