How to Prepare for APFS in macOS High Sierra

With the release of macOS 10.13 High Sierra, users have seen a drastic change in Apple’s default file system as well. After years, Apple has come up with an advanced file system with better features. Known as APFS (Apple File System), it has tons of new features like complete disk encryption, logical drives, machine learning, and more. Though, if you wish to upgrade your Mac to High Sierra, then you need to prepare your system. In this post, we will teach you how to prepare for APFS in macOS High Sierra.

How to prepare for APFS in macOS High Sierra

If you want to have a trouble-free experience while updating your system to High Sierra, then you should take some extra measures. For instance, you should know whether your system is compatible with the update or not and how the Time Machine backup can be converted. To learn how to prepare for APFS in macOS High Sierra, go through these points.

Compatibility

To start with, you need to know whether your system is compatible with macOS 10.13 High Sierra or not. In a nutshell, these models can be updated to macOS 10.13 High Sierra:

You can go to your Mac’s configuration and view its model, under the "About this Mac" section. In a nutshell, if your system is running on macOS X Mountain Lion 10.8 or later versions, then it can be upgraded to macOS 10.13 High Sierra.

The APFS is also functioning with other devices running on watchOS 3.2, tvOS 10.2, and iOS 10.3 or their later versions.

Compatibility with other devices

By upgrading your system to macOS 10.13 High Sierra, its file system will automatically be updated to APFS. Though, when it comes to other devices (USB flash drive, external disks, and more), then you need to be a little cautious. Devices that are running on any other file system can be accessed by APFS. Nevertheless, if you have formatted them as APFS, then you can perform read/write operations on High Sierra only. To access them on any other macOS (or Windows), you need to format them again to the respective file system (like HFS).

File sharing on APFS

One of the most evident changes about APFS is regarding file sharing. If your system is having an APFS, then the old Apple Filing Protocol (AFP) won’t work. Therefore, you won’t be able to share files in the usual way. Nevertheless, the new Apple File System is compatible with NFS (Network File System) and SMB (Server Message Block). You can also make share points on SMB encryption as well.

Support of Time Machine with APFS

When you are upgrading your system to APFS, don’t make any customized changes in Time Machine. Your Mac will automatically convert your existing backup to the APFS supported format. Though, the share points in Time Machine can’t be shared over AFP, but SMB instead. Nevertheless, you can’t take Time Machine backup in APFS and convert it to HFS or any other format.

Boot Camp in APFS

This is one thing that has confused a lot of readers before they prepare for APFS in macOS High Sierra. To be clear, Boot Camp supports the macOS 10.13 High Sierra. You create a Windows volume on High Sierra as well and use them readily. Though, the Windows volume doesn’t have the permission to read or write the APFS formatted drive.

FileVault in APFS

Encryption is a crucial part of the new Apple File System. If you are already using FileVault for encryption, then you don’t need to worry. Your system’s drive will automatically be converted to APFS (with the inclusion of the FileVault volume).
