Hey, I signed up today and this is my very first post. I hope I'll get help; which I desperately need right now. I just tried to uninstall and remove ubuntu from dual boot on Mac by just deleting the partition. Basically, I went to the 'Partition' tab and clicked both the partition and removed it. Now when I went to disk utility it seemed odd. It is showing the internal drive is divided into two sections and there are also two external drives namely MacBook Air and Container Disk..... Did I do anything wrong? If yes, what should I do now it solve it?
