As J D posts, it appears to be 1024 bytes. Since Mac OS is unix based, the name of a file or folder is actually the entire path. There's not really a path and a file name. So, you could have a 1023 byte name set at the root or a 1 byte name buried in a path that is 1023 bytes long. Or, anything in between.

*$ grep PATH_MAX /usr/include/sys/syslimits.h*
*#define PATH_MAX 1024* /* max bytes in pathname */
