As far as I know, honorbuddy is not developed for Mac, but if you multiboot with Windows on your mac, it can be done =)
Honorbuddy is written in C#. C# is a MS compiled language. No chance for a native execution of HB under MacOS. You will need a Virtual Machine.
VMware is really good software, except it can delay the game a bit and mouseklicks is not going to happen(if you need to move the toon or anything). The delay does(from my experience) that HB gets slower in gathering and similar. (rounding up = if you on bootcamp gets 100herbs in 1h you might get 80 in VMware) So, if you have the time to reboot for windows, go for it. If you need your mac'side running, VMware does a fair job, but not as bootcamp or a windows pc. Running with: Code: Model Name: MacBook Pro Model Identifier: MacBookPro6,2 Processor Name: Intel Core i7 Processor Speed: 2.66 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache (per core): 256 KB L3 Cache: 4 MB Memory: 4 GB Processor Interconnect Speed: 4.8 GT/s I cant really prove this, just my experience.
May I suggest you to install BootCamp or Parallels software? And, do not forget to read this thread: http://www.thebuddyforum.com/support-issues/22130-mac-os-x-answer.html
