Apple removed support for AFP. What file service should I use to access files on Synology NAS?

Details

Starting from macOS 11.0 Big Sur, Apple no longer supports AFP servers.¹ As such, using AFP to connect to Synology NAS may pose increased security risks for clients and result in the inability to obtain technical support from Apple.

For security reasons, Synology will terminate AFP Service in future DSM versions. We strongly recommend using other file transfer protocols as replacement, such as SMB Service.²

Notes:

Third-party news article regarding the deprecation can be found here.
If you use the following services and switch to SMB Service as your file transfer protocol, reconfigure the settings to ensure that they can function normally:
- Mac Finder
- Time Machine Backup
