Merging a partition.

I've used Bootcamp to create a windows partition on my MacBook Pro (Retina, 13-inch, Early 2015). This has been working for a long time, and never stoped working. But because I started to use windows less and less I decided to delete the partition and put the available space back into the main drive, merging the drives for MacOS. This turend out to be more difficult than it should be. Bootcamp assistand manager did not help, so I looked on forums and tried to do a bunch of stuff with TERMINAL. This was all in vain and im not sure how to continue from now on. See the pictures & information below.


Software : macOS Mojave Version 10.14 (18A391)

Can you disconnect/eject the SD card? Once it has been ejected, run


  • Step 1


In your specific case, given the current state, try


diskutil eraseVolume jhfs+ BC1 disk0s3

diskutil eraseVolume jhfs+ BC2 disk0s4


diskutil mergePartitions jhfs+ BCMP disk0s3 disk0s4

diskutil list


  • Step 2


If you see only disk0s3 as the last entry under disk0, then run


diskutil eraseVolume fat32 BOOTCAMP disk0s3


and retry removing the partition using BC Assistant only.
