How to resize disk partition in macOS<article>
<section class="page">
<p>Apple made it easier to resize partitions—logical divisions of a disk drive into separate mountable volumes with different properties—several releases of macOS ago. A Macworld reader resized their main volume to 369GB to set up a Boot Camp partition, but then realized it was too small. They wondered how to fix this.</p><p>In the right circumstance, you can simply follow these steps without having to back up the entire drive, erase and reformat it, and add new partitions.</p><p>
Always back up your drive before attempting to resize partitions in case something goes wrong, or you accidentally click to proceed on a destructive operation.</p><ol>
<li>Launch Disk Utility.</li>
<li>Select the disk, not the volume, in the left-hand lists of disks.</li>
<li>Click the Partitions button.</li>
<li>You can now delete other partitions (select and click the - button), and type in the new size of your main partition in its Size field.</li>
<li><strong>Warning!</strong> Click Apply to proceed, and Disk Utility will warn you whether it will be a destructive operation, deleting the partition’s data and re-creating, or not. If it’s non-destructive, proceed.</li>
</ol>
<p>I haven’t found a complete consistency in which drives have non-destructive resizable partitions or not. You can read a lot of detail about macOS drive partitioning, and still find that a volume that meets all the parameters for resizing without erasing, and still be told by Disk Utility that the partition will be erased.</p><p class="jumpTag"><a href="/article/3243205/storage/how-to-resize-disk-partition-in-macos.html#jump">To read this article in full, please click here[/url]</p></section></article>
