Similar to Xcode free space requirement, but different details.
We could not complete your update
There is not enough disk space available to install the product.
The download size lists:
Version 11.0 • 7.6 GB
and my Mac has 31.2 GB available according to About This Mac : Storage
My question is this: How can I discover what the exact storage requirements are for this update without performing the update? I'm looking for a definitive answer, not methods for estimation. Thanks!
EDIT: I'm not looking for sector-specific values. I'm just trying to understand how much available storage is actually required for a successful update—clearly it's not 7.6 GB.
EDIT 2: Mysteriously, Xcode now updates with no change in available storage space. In fact, it appears I have a few hundred MB less available storage than before.
