Hi All, I'm using Yosemite on my MBP : 13',late 2011, 2.4GHz i5. I am a light user; browsing, word, excel, music etc. I feel comfortable using Yosemite; its the only OS X I have used, being a former (life long)windows user. I have not yet considered updating to any other OS X, even though I have read on this Forum that my MBP will support HS. I am considering a 'clean install' of Yosemite, just to refresh the MBP a bit. Who else is using Yosemite in 2018? I am curious about the reasons. Also looking forward to hear about lil details about Yosemite that you find better suited to your needs. TIA.
