Unable to Mount - com.apple.DiskManagement.disenter error - 119930872

I've tried reformatting, changing formats, terminal mount etc...

I thought this might be a specific hard drive issue, but turns out none of my hard drives mount.

I see the drives inside diskutil, however the volumes are always greyed out.



I'm not sure this is a Catalina Issue, since the issue was happening prior to me updating. Regardless updating it to Catalina didn't work.


I have 2 Lacies and a Toshiba.

They all work fine w/ my older macbook air.


Not working for:

MacBook Pro (15-inch, 2019)

2.6 GHz 6-Core Intel Core i7


Able to mount on:

Macbook Air 2012 13in

2GHz Intel Core i7


I purchased Disk Drill (thinking i need recover data) and was able to recover files.

But the real issue is my macbook pro, seeing that I can view the files perfectly fine on my macbook air.


Anybody else seeing this?

Please help!


Thanks in advance!

So after calling customer support and trying everything, nothing worked.

  • Reinstalling Catalina
  • starting in Recovery Mode (I could mount / dismount), but didn't do anything
  • ctrl + option + shift (7 seconds) etc...
  • terminal diskutil mount...



But I did find a way, to get things to work.

  • restarting
  • plugin your external drives.
  • Logout of the current user, and then log back in.


Hope that helps anybody’s else out there.
