Hi,
Just wanted to update you all with where I'm at with this.
jata1.... Thankyou for your detailed explanation and taking the time to reply to me. I really appreciate it and you will be happy to know that things are working!
I think it was a combination of a few things. I went back and did everything from the beginning and followed your steps.
Hadnt enabled the correct file sharing setting on my Mac, also re-did the smb permissions.
The other issue I found was to do with the ufw firewall on my RaspberryPi. I completly cleared all rules and set it up again from scratch making sure the following ports were open: 137, 138,139, and 445.
Everything is now working perfectly and I can see all my shared folders on my Mac.
Thankyou everyone for your help.
