Hi!

I can't make my Mac ethernet file sharing to work between two older (circa 2010)Mac Pros. One machine is actually a mid 2009 4 core that I upgraded to a 6 core 3.46Ghz.32GB (master). The other Machine is mid 2010, (slave) 12 core 3.33Ghz, 64GB. The Model Identifier on both machines is 5,1. OS is Mojave 10.14.06.

I have the Vienna 7 Server on the slave with my VI's and trying to send the info to DP on my master machine. Both machines say Ethernet is connected and working:

Master: Ethernet 1 is currently active and has the IP address 10.0.0.1.
Slave: Ethernet 1 is currently active and has the IP address 10.0.0.2.

and I can see both machines in the network settings on the "opposite monitors. Screen sharing actually works. However, when I try to connect to file sharing the connection fails.

I am trying to connect via USB-c cable, however it makes no difference whether I'm on the Ethernet or USB-c cable, the results are the same. Does anybody have any experience with this?? Help!!

If you are directly connecting one Mac to the other and not going through any type of router, one possible reason for the problem is you might need a Ethernet *crossover* cable as opposed to a standard Ethernet cable.

I just saw your reply, Thanks!! I did get it working. Now some how I need to figure out the routing!

Thanks Again

Crossover cables shouldn't be required on a 2010. The Mac will know.

Apple Support has a number of docs online about file sharing. Which ones apply depends on the Mac.

One of the machines was 2009. I was just “spitballing.”
