WalterT What would be the address to the samba share
The standard Internet Protocol designation is
smb://<ip-address>
e.g.
smb://192.168.1.123
where 192.168.1.123 is the IP address of the ASIAIR itself. Just like you access a http ("web") server using http://<ip-address>
On macOS, simply click on the desktop to activate the Finder. In the main menu bar select Go dropdown menu and choose Connect To Server...
This should bring up a small Connect To Server window. Click browse, and ASIAIR should appear as a Samba server. If not, just manually type the Samba IP address above in the text field that has your history.
After connecting to the ASIAIR once (I have 4 ASIAIR in my list; two v1 and two v2 :-) it will appear in the drop down Combo box each time you select Go: Connect To Server.
(NSComboBox is macOS Cocoa's UI that is a combination of a NSPopUpButton (a predefined popup menu) and NSTextField (for typing a line of text to add items to the popup menu)).
When you initiate connection to the Samba server, there will be a login window. You can only connect as Guest (unless you find the ASIAIR username and password through Raspbian) -- Guest login does not require a password. As guest login, you can't add or delete file (that's how ZWO had set it up) -- for that, you still need to directly manipulate the USB drive, or you can remove files and clear the storage with the ASIAIR Storage Settings page (Image Management), again without touching the drive.
Now, here is the best feature on macOS: once you mount the udisk Images volume to your desktop, you can make an alias of it, rename the alias, and keep the alias on your Desktop. In the future, just click on that icon on the desktop! You can rename the alias to be "ASIAIR" for example instead of UDisk Image. Or name one ASIAIR as ASIAIR-1 and another ASIAIR as ASAIR-2, etc.
I use a Samsung T7 (500GB) SSD with my primary ASIAIR, and don't even remember the last time I removed that drive from my waterproof box. I just power up ASIAIR and access it through my network.
You can connect to other kinds of servers the same consistent way in macOS. smb: is just for Samba. I connect to my files on my hostgator web site (www.w7ay.net) using http:, and I connect to other Macs on my local network using afp: (Apple File Protocol), and ftp: (File Transfer Protocol) to other machines on the Internet. ZWO did not open the ftp port of the ASIAIR, otherwise you could access the files using ftp://<asiair IP>. There is also no http server on ASIAIR (like you have on INDIGO Sky), otherwise you could access an ASIAIR webpage using http://<asiair IP>.
