Whether you’re transferring files to an external device or to another folder on your Mac, the speed differences is going to be very noticeable. “Any Time Machine share points must be shared over SMB instead of AFP.”ĪPFS is designed to make transferring files from one place to another faster. “After you upgrade your Mac and convert to APFS, you won’t need to make any changes to Time Machine settings,” Apple notes. The option to enforce only SMB-encrypted share points is also available. SMB and NFS shares are supported when using APFS, according to the support document. If you use macOS’s File Sharing feature, keep in mind that APFS-formatted volumes don’t support share points over the network using the Apple Filing Protocol (AFP). That’s because Boot Camp in macOS High Sierra doesn’t yet support read/write operations to APFS-formatted Mac volumes. If you use Windows on your Mac desktop or notebook via Boot Camp, you won’t see any changes after upgrading to macOS High Sierra unless your Boot Camp volume is greater than three terabytes and resides on a Fusion Drive.

If your Mac is using CPU-intensive FileVault encryption, those volumes will be converted from HFS+ to APFS just like unencrypted ones.
