iCloud for new computer
Hi,
I apologize if this has come up before but I need to be certain of the answer before doing anything.
I recently got a new office mac computer and have been working off of that using iCal, contacts, mail etc. Now I need to have this information on my computer at home and I'm not sure how to sync up with icloud. I currently have an iCloud account but it has all of my home computer stuff on it. How can I sync up with iCloud so that the data on my office computer will override the data on iCloud? After which I can sync my home computer up with that info. Basically the new computer needs to be the main database and I need to update my home computer, ipad and iphone with this information, specifically with iCal. Any tips?
Thanks
MacBook Pro, OS X Yosemite (10.10.3)
