makiwara Posted December 12, 2017 Share Posted December 12, 2017 Hello I have the same kind of configuration as yours. (GA-H77-Wifi, i5 3rd gen, 16Go RAM) I was previously on Sierra and was stuck installing High Sierra because of my graphics card GT630 that somehow wasn't working with all the required drivers. So I suggest that you move to Sierra first and see how to move to High Sierra later on Just for you to know High Sierra 10,13.2 improves performance a lot vs the previous sub version. Maybe it might help 1 Link to comment Share on other sites More sharing options...

makiwara Posted December 12, 2017 Share Posted December 12, 2017 I always recommend a clean install. Copying and adapting the config.plist file before hand 1 Link to comment Share on other sites More sharing options...
usx Posted December 14, 2017 Share Posted December 14, 2017 I did manage to make an upgrade and the upgrade itself ran smoothly, however I forgot to disable the AFPS conversion, and the computer felt sluggish afterwards, so I made a complete Timemachine backup and I'm currently fighting the install. I have to mention I'm using GTX 750, everything else is the same as your configs z77-ds3h + 16GB of RAM. 1 Link to comment Share on other sites More sharing options...
