Hello guys. I have a 2013 rMBP which had every option added when I bought it. It it showing signs of ageing and I am wondering it upgrading to High Sierra from what I have is worth the hassle of clearing the macbook, installing the new macOS and then downloading all programs again? Going from iOS10 to 11 I don't notice any difference except for the poor UI. Am I going to notice any difference if I go from Sierra to High Sierra, or should I just keep with what I have?
