[Solved] iCloud Drive migration
I have two Macs sharing a common iCloud login and iCloud Drive.
I have a large folder of files on an external SSD that I would like to be in iCloud Drive AND downloaded to both Macs.
I don't want to use double-bandwidth. That is, (1) to put in iCloud Drive on Mac1 and have it upload. (2) to download it from iCloudDrive to Mac2.
Instead I would like to copy the folder via the Finder to the iCloud Drive folder on both Macs, perhaps to Mac1 first and allowing it to upload, and then via the Finder to Mac2 and hope iCloud Drive will recognize it's presence on Mac2 and avoid the download needed by (2) above.
Will this work? Any caveats? ( It must be a common situation. Getting a new Mac has blasted my Comcast monthly limit. But Comcast limits and so on are not the question.)
I know exactly what you are looking to do. The feature you are looking for is called LAN Sync and that is something that Dropbox has that iCloud Drive does not. Yes, it is a problem with companies like Comcast that are stingy with bandwidth and does slow down setting up new computers but for now it really is the only supported way to do this.
I wonder if macOS's Content Caching would cache this kind of data, too?
