I found this answer very useful; hdiutil works just fine where Disk Utility refuses with that "disk image cannot be resized" message.

Thank you, it's always hard to figure out what unit each different utility uses. Some use Gigabits, others Gigabytes, and it's not clear what a g or G are meant to represent.

@Kamafeather — In 150g, the g represents 1024^3, not 1000^3, so 150g works out to approximately 161*1000^3 bytes.

Funny that in my case I specified -size 150g but it resized to 160GB 🤷♂️. However it worked, thank you! +1
