screen /dev/tty.usbmodem1d11 9600

This is the standard command to open a serial console with the device attached to port /dev/tty.usbmodem1d11 at speed 9600 bps.

For me, everything is normal as this is the standard procedure.

I'm sorry I can't be of much help as I don't know the specifics of your configuration.

HI! Just to answer, now the serial is working! Why? I deleted every library that I don't need in makefile (in other words, I delete all library from the minimum project). Maybe some library cause the problem, maybe not. I also deleted all files that I don't need, maybe it helps.

And now I discovery the git problem is not exclusively from your project, every project has this problem. Thanks for all the support.
