Hi Ian, I also jumped from Lion to Sierra recently but my old Macbook pro with a HD slowed down a lot and it took a couple of days to be functional again (you have to reinstall XCode, XQuartz,…). OTOH, note that Firefox is not maintained for Lion since end of 2016 I believe. Not very secure. Finally my MBP died and I moved to a more recent one with a SSD + 16 Gb ram and speed has resumed to normal…
