You should get a NAS. If you want TimeMachine you get some drive or Apple's solution. What I read you trying to do doesn't seem to work.
I want to use my Macbook Pro 2009 as NAS for my Timemachine backups.
But I have the following problems:
On the old Macbook the entry < Advanced Options> does not appear under the shared files when right-clicking.
In the system settings Timemachine in Mojave under <Select backup volume> only the Airport Extreme appears, but no other possible volume.
What have I done wrong? Can anyone help me?
I would be very grateful for help.
