AFAIK, recent (Intel-based) Macs with UEFI firmware should be able to 
support ESP formatted with FAT.

At this time, syslinux.efi has no support for HFS+.

Even if the firmware itself supports HFS+ (so you could find 
syslinux.efi from the firmware shell), syslinux.efi would not know how 
to find/use the next files (ldlinux.e*, then the syslinux configuration 
file and so on).  

In the future, there _might_ be some way to load additional filesystem 
drivers, although this is not at all a "near" future - not that I would 
know how to code such feature - and my guess would be that HFS+ would 
probably not be the first to be added / supported.   

GPL-compatible additions are very welcome.
