Im running yosemite on my imac late 2013 and 2014 mba with no issues. i would like to upgrade to el-capitan bit issues regarding outlook, email and office are stopping me. i work a lot with word so at the moment all talk of compatability issues etc are putting me off as i need office/outlook for work. if im happy now i cant see a reason to change unless i can be very sure capitan wont interfere. it would be nice to have the latest os too. any help please appreciated.
