So after a decade my 3,1 is still going strong. I am however starting to run into some software issues still running 10.11.6. I'd like to avoid High Sierra and the AFPS change over. I have read through the upgrade thread and plan to use the dosdude patcher. I have a flashed 680. Will this work ok for the upgrade process? Any reason not to upgrade? Is there a direct download link for 10.12.6? Thanks!
