I have a 500 GB SSD. At one point, it had 2 partitions--one for my regular macOS boot (430 GB), and one for developer previews (~70 GB). At some point, I deleted the developer preview partition, but the freed up space didn't flow back to the main partition. Also, I wasn't able to resize the Macintosh HD partition back to the full 500 GB. How do I get my 70 GB back on the Macintosh HD partition?
Here is the output from
diskutil list showing the total drive size and only 429.4 GB available:
