"Sync" can mean a whole lot of things. You may mean you're preparing to get rid of your iMac, and want to set your MacBook Air as your new computer. (In that case, you would use Migration Assistant.)
More likely, you may mean you would like to keep calendars, contacts, emails, photos current on both machines. That's what iCloud does for you.

If you really want a no fuss solution I'll give you one that I've been using not for nearly a year. There are additional benifit's at least check it out at Synology .com
1. Purachase a Synology Disk Station (DS) I recommend for home users the DS112 ($199 + $100 for 2TB HDD) or DS112J ($149 + $100 fo 2TB HDD).
The DS has a app called Cloud Station (CS) that works just like DropBox with one exception you have 1, 2 or 3TB's of storage (depending on the space you choose) and the SYNC is much more secure since it's on your own home network. You can also set up CS to sync over the Internet which is more secure than DropBox IMO. You don't have to be a network expert by any means to set the DS up.....very simple instructions (do some reading and reasearching while you wait on your order). If you do need help Synology is very responsive to phone calls and emails. And the best thing about Synology they are very MAC friendly. And if you use Time Machine to do regular backup what's synced in CS will be backed up, because Cloud Station is just like another folder residing in your Home folder.
There are also YouTube videos on how to set up DS and CS. If you do decide to get one I'd be glad to help you set it up!!!!!!!!!
BTW, I used Chronosync but didn't really like it, seemed like I was always having to perform a manual sync and there were issues with some of the files syncing properly, that was my experience. Others may love it I didn't.
