Hi folks, I just recently purchased the newest refresh late 2015 iMac 27inch model and loving it so far, just one small bug that is nagging me is that I am unable to set any receiving e-mail in OSX El Capitan Mail application to size 18? My fonts and colours preference are set to Menlo, size 18 for easier reading but I am unable to change the system regular font 12 to 18? I do not know how to change? It is greyed out? See attach file. Any ideas? Thank you, Boabyboy P.S. I am aware you could change to classic view or use command + or - to zoom text in an out but I feel there should be a way to change receiving mail text to 18 automatically than having to manually do this for each e-mail you receive is there not?
