Problem with Time machine

Hello,

I bought WD My Cloud 4TB before 1 week and I have a problem with the Time machine. I cannot find the unit as an opion on the disk selection for backup. I am trying to solve this problem for a week but nothing changed. 

Please if you have any solutions tell me, I dont know what to do and I want ot backup my Mac as soon as possible. 

Please help me Iam desparate, If I dont find a solution today I will throw it in the bin and I will go for Synology!!!:angry:

Did you enable TimeMachine backup in the NAS admin UI?

how can I do that?

If you mean from the dashboard yes.

I had same issue. The option for the drive is the very last icon on the bottom. you have to scroll down to see it in the time machine preferences. 

where exactly?
