can you directly plug in the usb c cable in both Macs or use some app in order to directly copy files form one to the other?
 
If the files aren't large, use bluetooth.

If the files ARE large, use a USB flash drive.
 
Hi Pangalactic,

If both machines are on the same WiFi network, and if you don't care about how long the transfer takes at WiFi speeds (say overnight), then you might also think about using rsync. It transfers directories and files along with all permissions and performs checksums to verify the transfers. It also does incremental backups if desired.

The Terminal command to use would look something like:

$ rsync --rsh='ssh -p22' -avz <source-machine>:/Users/<source-username>/<Directory-name-to-transfer> <recipient-username>@<recipient-machine:/Users/<recipient-username>

where:

<source-machine> is the source computer, something like "MyiMac.local"
<source-username> is the login username of the source, something like "MyName"
<Directory-name-to-transfer> is the path name under the source's login directory to the directory to transfer
<recipient-username> is the username of the recipient
<recipient-machine> is the recipient machine, something like "MyMacBookPro.local"
<recipient-username> is the login username of the recipient

which places the directory tree from the source into the login directory of the recipient on the recipient machine.

Just another way to transfer files between machines. It works over any network and any connection, including WiFi, ethernet, USB cable, TB cable, even between two users on the same machine or between the internal SSD and an external disk drive.

If you want to avoid using target disk mode, and if both of your Macbooks support Thunderbolt, then you can use Thunderbolt as a bridged network. But you can't use just any USB-C cable, it has to be a Thunderbolt 3 cable with USB-C at both ends.

Hi all,

While I still prefer "rsync" for transferring directories/files, for the last week or so I've been tinkering with Universal Control's "drag-and-drop" between two MBPs, and this seems to me to be the simplest method, even easier than AirDrop. While Universal Control is still in Beta, it should be available sometime this spring (northern hemisphere)/fall (southern hemisphere).

P.S. For me personally, "rsync" is the fastest way and much faster than UC's "drag-and-drop" to transfer files (you don't have to use the GUI to drag the cursor across two displays as you do for UC; and for rsync an up-arrow/RET is all that is required to perform the differential transfer). Plus, if you are backing up or performing any type of differential update, rsync will transfer just those files that have changed since the last rsync, saving a lot of bandwidth. Rsync also operates bi-directional, and you don't have to be physically close to the other machine (rsync even works over the Internet).

Edit: And one more thing, UC's drag-and-drop only works between computers logged into the same accounts (same AppleIDs). "Rsync", on the other hand, allows one to transfer files between different accounts on different machines as well as different accounts on the same machine.
