I used to be one of those upgrading ASAP whatever it was, computer OS, phone OS, digital camera firmware, water flush firmware... now I am more conservative, some of my Macs still run on El Capitan and I am fine with them, the one running Sierra is the 2009 27" i7 8GB iMac whose I upgraded to an SSD, so far it should be one of those eligible to upgrade to HighSierra but was wondering if worth the pain to upgrade, I am not into cosmetic any longer, I also think that it's quite a while nothing happens on both hardware and software fronts and as such I am fine as I am but would like to know from you if there is anything, besides the file system, which makes it worth to risk upgrading.
Grazie
