Hello Folks I have a Macbook Pro Mid 2012 (on Mojave) that has an internal SSD disk with 2 partitions: MommyMerge (APFS format) - Partition #1 DaddyTemp (HFS+ format) - Partition #2 ran diskutil list and here's terminal display: I've been trying to delete the 2nd partition and merge it into the 1st. Ran Disk Utility but haven't had any luck. Tried these: Erase partition #2 but cannot delete it. Resize partition #1 but cannot. None of these is core storage, and the other weird thing is that partition #2 is defined as Apple Boot although partition #1 is what I boot into. Checked System Preferences | Starting Disk to verify. My goal is to only have 1 partition to boot to and also store all my data. Any suggestions? Thanks.
