I need to transfer a lot of files between two 2019 MacBook Pros, but when I connect them using a Thunderbolt cable, the bridge never connects and assigns an IP via DHCP.
I tried manually assigning an IP and subnet mask to both of them, but still can't connect them.
What is wrong here?

Using a Thunderbolt Bridge with Internet Sharing
This is an example where a Thunderbolt bridge was be setup to transfer files. This was done using legacy Thunderbolt. I assume the same procedure would be used with Thunderbolt 3. The host computer is connected to the internet through ethernet using a DHCP assigned IP address of
192.168.0.88
and subnet mask of255.255.255.0
, so I setup the Sharing pane of System Preferences as shown below. You could also use Wi-Fi.I have a Thunderbolt 2 cable connecting the two Macs. On the client computer, I setup the Network pane of System Preferences as shown below. I needed to select the
Renew DHCP Lease
button. The client is current not connected to the internet by Bluetooth, Ethernet or Wi-Fi.I setup the Sharing pane of System Preferences on the client as shown below. Note: In my case, the image shows I can connect to the client from the host by using
smb://192.168.2.2
.From the menu bar of the Finder application on the host, I can select
Go->Connect to Server...
and entersmb://192.168.2.2
, as shown below.Proceed by selecting the
Connect
button.Using a Thunderbolt Bridge without Internet Sharing
I suppose internet sharing is not required. For example, the computer, referred to as the client, could have been manually setup, as shown below.
And, the computer, referred to as the host, could have been manually setup, as shown below.
With the above configuration, the Sharing pane of System Preferences, for the computer referred to as the host, could have internet sharing turn off, as shown below.
