I am running a FRITZ!Box 6591 Cable as my wireless router in my home. I have connected a 1.5 TB Toshiba external HDD to this router via USB. The drive is formatted as NTFS, but to my knowledge that shouldn't matter here to the Mac, since it is a network drive,

I can access the drive on both of my windows 10 PCs via \\fritz.box\fritz.nas

However, on my Macbook running MacOS Catalina (10.15.3), if I open Finder and press ⌘-k, and then try to connect to the NAS via


I get a window asking me for my login-credentials, which I enter (same as on the Windows 10 machines), but the login fails, and I am not able to access the drive.

At first I thought this may be due to the NAS requiring SMB1, which does not seem to be supported by Catalina out of the box. So I followed the steps at https://apple.stackexchange.com/questions/362739/what-causes-some-network-drives-using-smb-no-longer-connect-to-macos-catalina/363648#363648, and then restared my Macbook.

However, I am still getting the same issues.

How can I connect to this NAS via my Mac?

  • This is a shot in the dark, but try connecting with cifs://fritz.box/fritz.nas – Gordon Davisson Mar 23 '20 at 17:39
  • Thanks @Gordon. Unfortunately that doesn't work either, with the same problem occuring. – Chris Mar 23 '20 at 18:44
