Write permissions on a new encrypted partition The HD of my MacBook Pro (macOS Mojave) is encrypted with FileVault.

Yesterday, I created a new partition from the Macintosh HD (APFS) using the DiskUtility and called the new partition Data (Extended Journaled).

The problem is that now I cannot copy any files to the new partition. It seems that I don't have write permissions to write anything on the new partition.









Why is that and how can I fix it?
I assume this happened as you have used the partition on Extended Journaled
Open the finder, find the drive under ‘Devices’, then right-click and select ‘Get Info’.  A dialog box should pop up and display the basic info of the drive. At the bottom, there is a collapsed menu for ‘Sharing &amp; Permissions’, make sure your username has read and write permission, and check &quot;Ignore ownership on this volume&quot;

If you are unable to do this , then first try to disable Journaling, and do the previous step shared above
Open Disk Utility, Select the partition and then hold down the alt key. Select the file from the top menu and you will then see an option to ‘disable Journalling’
