Yesterday I tried installing Windows using Bootcamp but as usual, it didn't go well after partitioning. BC Assistant wasn't able to remove its partitions either. So after reading around, I managed to format the 50 GB that I allocated to BC into FAT32 and then into APFS and I tried to increase the main APFS volume (that has macOS and every thing) using (I used the correct disk identifiers, not those names mentioned below)
diskutil apfs deleteContainer disk0s3 diskutil eraseVolume free n disk0s3 diskutil apfs resizeContainer disk0s2 0
However it seems like my main volume's size didn't increase and the 50GB are no where to be found. Here's my latest
diskutil list and also note that BC Assistant won't fix anything on its own.
PS: What's wrong with BootCamp Assistant? It always never work without issues. First attempt it failed at partitioning, second attempt it partitioned and then it failed and tried rewinding but then it failed again. Is there a way to fix it without having to reset all my Mac?
