Different computer problem

I always program and save on my 6yr old mac which has much more storage space. I have a yr and a half newer mac. My older mac will not save to SSD. My newer mac will but I still program and create on my older mac. Called Jay, yesterday. Hopefully, I will get a response today.

A screen shot for each of the following would help:

  • What’s the MacOS on the old Mac
  • What’s the MacOS on the new Mac
  • How is the SSD formatted? Use Get Info-not the Disk Utility

This. This, right here.
