Mounting exports on macOS

For macOS (OS X) exports, use this format, with these explicit options:

mount -t nfs -o timeo=9000,noatime,vers=4 SwarmNFSserver:/ /mnt/SwarmNFS

• Increase the timeout, timeo, to 9000.
• Enable noatime (no access time), which lets the system skip updating the file system for files that are simply being read. This has no effect on the write time information, which is always updated with every write to the file.
• To ensure that you mount using the expected protocol, add the "-t nfs" and "vers=4" mount options. The macOS client is restricted to NFS v4.0.
