Hi all, After much delay I finally upgraded my mid-2007 iMac from 10.7.5 to El Cap. 10.11.6. Everything seems to have gone very well. Surprisingly well, given the straight leap from older to newer (and this old Mac can't run Sierra, so that's it for this old beast). However, iCal is not showing any data beyond what is "found in mail". All my previous data is missing! I don't know why it didn't move with everything else. I presume the iCal .plist in Preferences would've been integrated, but no. Any advice would be appreciated!
