Is it possible to automatically sync my iMac and MacBook Pro
If iCloud Drive (FAQ) isn't syncing fast enough for you (or you're not on El Capitan ) then you could try a commercial solution (per Gb most are cheaper) or you could use one of the "roll-you-own" solutions.

There are multiple commercial solutions that do this, in no particular order:


Dropbox
Microsoft's OneDrive
Box
Google Drive


Then there's a range of self-hosted solutions which let you use your own network, servers etc to provide cloud storage &amp; sync.

Of course if you put your laptop to sleep if will always have sync changes from your desktop when it wakes up no matter what solution you use.
