Rather than duplicating the original, the cloned file stores the changes that are made to it in the metadata and points to the original for the rest of the data. It is essentially a writable clone of the original file. There is a caveat with this ‘copying’ though. You will never see a Duplicating file window again. Before we updated the 4GB file copy took 8.41 seconds.

We ran our usual file transfer speed test before and after the update to High Sierra. When it comes to copying large files the process will be faster. That’s not the only way that Apple’s switch to APFS will benefit you. When you first look at the storage graph that your Mac generates you may be disappointed, but patience is a virtue and after your Mac has finished its shift to APFS you can expect to be rewarded with some lovely free space. We were curious to see whether we’d see increased space following the installation of High Sierra on our Macs, so we took a trip to the Apple menu > About This Mac, and checked the Storage stats before and after the installation. iOS 10 rolled APFS out to iPhones and iPads back in 2016, and when users updated their phones to the new OS they were pleased to see that they had recovered a few GB of space. It’s not just the Mac that uses APFS either. You will just have to take our word for it.
But the changes add up to a faster, more secure and more stable operating system. The sad thing is you probably won’t notice this unless you work with large files. This time round Apple has completely overhauled the way that the macOS manages and organises your data, as well as adding support for new photo and video codecs that will mean that your increasingly large media files take up less space. Where Show Leopard rewrote the Finder in Cocoa, brought Grand Central Dispatch, and improved power management, Mountain Lion bought Gatekeeper and focused on making it easier to manage and synchronise content between multiple Apple devices. Each bought a handful of new features but mostly focused on under-the-hood changes, rather than improving the apps we use day-to-day. These were smaller updates that came after the more flashy Lion and Leopard versions of OS X.

We were expecting High Sierra to be an update similar to Mac OS X Mountain Lion and Snow Leopard.
