I have partitioned my internal drive on my MacBook, and I now need to increase the available space on the startup volume slightly to make space for growing photos library and iCloud.
However, Disk Utility does not allow me to drag the handle in the partition to enlarge it, though it will let me reduce the size.
Anybody know why I can only reduce the startup volume size and not enlarge?
Disk Utility 12.x: Partition a disk
To enlarge a partition, you must delete the partition that comes after it on the disk and then move the partition’s end point into the freed space. You can’t enlarge the last partition on a disk.
You need to delete the partition immediately below it, or if there’s another partition formatted as Mac OS Extended (Journaled) on the volume, move the library there.
The Disk Utility can’t change the starting point of an existing partition.

Hi macjack and thanks for replying. So let's call my startup disk volume 1 and my data disk volume 2. Would it work if I reduce the size of volume 2, letting disk utility create volume 3 in the new space, and then delete volume 3? Or would it only result in volume 2 retaking that space? Is the only way to increase volume 1 to delete volume 2 and then re-partion it smaller?

As I understand it yes.
