First, enable 'NAS' on the B2.
On the B2 front panel, select 'Settings' --> 'Maintenance' --> 'Start NAS' and click on this.
I would also recommend that you check that your B2 software is up to date, at the time of writing that is 'B2B Jul 21 2020' or 'B2 Jul 21 2020'
From the Mac desktop:
1. Click 0n the 'Apple' icon (top left icon)
2. Click on 'Select Preferences'
3. Click on 'Sharing' icon
3.5 At the bottom left of the window click on the icon 'Click the lock to make changes'.
3.6 A new sub window opens up asking you for your user password; type this into the 'Password' field.
4. In left side menu of the 'Sharing' window, tick 'File Sharing' box; the status should show 'File Sharing: On' with a green indicator showing in the middle of the window.
5. On the right hand side of the 'Sharing' window, click on the 'Options' button
6. In the new sub window that appears, tick the 'Share files and folders using SMB' box.
7. Towards the bottom of this window under 'Windows File Sharing:', where 'Account' is displayed, tick the 'On' box for your Mac user name.
8. A sub-window 'Authenticate' shows. Enter your Mac user password in the 'Password' box.
9. The sub-window will close, and then in the 'Sharing' window, click on the 'Done' box.
10. You can close the 'Sharing' window now.
11. On the desktop, open up 'Finder'
12. In the left side window, click on 'Network'
13. You should now see 'brennanb2' listed in the right side window.
14. Highlight and click on 'brennanb2'
15. You should see a status of 'Not connected' (this is correct)
16. On the top right of the window you will see a button 'Connect As ...'
17. A window will open up 'You are attempting to connect to the server 'brennanb2'
18. Click on the 'Connect' button
19. A new window opens up showing 'Enter your name and password for the server 'brennanb2'
20. Then click on the 'Registered User' button.
21. In the 'Name' box, type in 'root' (without the quotes)
22. In the 'Password' box, type in 'brennan' (without the quotes.
23. Tick the 'Remember this password in my keychain' box.
24. Click the 'Connect' button.
25. A window will open up showing your music folders on the B2.
Now that you have established the NAS connection from your Mac to the B2, each time you start up or reboot your Mac, the 'brennanb2' should appear in the network section of 'Finder'
I have noticed that, after a reboot of the Mac, it may take five minutes or so for the NAS connection to be re-established, so that's the time to put the kettle on!
Also, if you have a lot of music files, the directory listing might take a minute ot two to appear on the screen. You might see the 'loading' icon spinning for a little while.
However once the list is showing, the response times are good when you are manipulating files and folders.
I have tested this on 'High Sierra' and 'Catalina' versions so far.
I have only owned the Mac for a few days and am not familiar yet with Apple products, so if you find any errors or omissions in these instructions then please let me know and I'll apply the changes.
I can confirm that the Web UI works fine on a MacBook using safari browser.
NAS is also very simple.
Make sure NAS is enabled on the Brennan.
On the Mac open a Finder window and select 'Network' under 'Locations'. You should see the Brennan listed (as brennanb2) along with other network devices, although it might take a little time after switching on NAS on the Brennan.
Double click on brennanb2 and at the top right of the Finder window click on "Connect As".
Enter the Brennan login details (Name= root Password= brennan) and select the "Remember this password in my keychain" box.
Click on Connect.
You will now the the Folder 'Music'.
Double click on that and you will see all of your music collection. It will take a few seconds to load.
I've just done this for the first time as I was writing this, so these settings work for me, MacBook Pro, Big Sur. I've rebooted the Mac to test, and the Brennan showed up in the network as before and the password did not need entering again.
