For the most part, dont expect jaw-dropping changes or totally new interfaces.

Instead, you get new features such as Safaris autoplay blocking, the ability to edit iPhones Live Photos in Photos, and really fast file copying on SSDs.

On the other hand, that means no sea-changes to your existing workflows, and some nice quality-of-experience enhancements if youre a big user of those applications.

Performance is virtually identical, at least on an up-to-date MacBook Pro (13-inch).

File moves are instantaneous under both High Sierra and Sierra, but copies of large files (like a 4.3GB ISO image) are instantaneous on AFS, the updating disk file system thats now default for anyone who doesnt have a Fusion drive or an old spinning hard drive.

Your system has an SSD, not a Fusion Drive or HDD Youve updated your iPhone or iPad to iOS 11 and shoot photos and videos with the new file formats Youre a big Photos user You have a complicated family to manage with iCloud Youve been screaming for the specific capabilities added in those particular applications Updating will also get you the latest security fixes (the Keychain exploit above notwithstanding).

That said, my standard recommendation is to wait at least a month before updating and let the early birds find the most glaring problems and glitches, which are generally handled by followup point upgrades.

At the very least, AFS 64-bit addressing is essential to the upcoming iMac Pro for many reasons, not the least of which is the ability to support that systems configuration with a 4TB SSD and higher.
