iCloudDisk lets you sync files between your Macs using iCloud, like iDisk.
iCloudDisk is the easiest way to use your otherwise-unused iCloud storage space for syncing files between your Macs. iCloudDisk creates a folder on your computer which is seamlessly synced using your iCloud account. Files are even saved for offline use.
Note: You must run iCloudDisk on all the Macs you want to sync with.
