Razer is unfortunately one of those companies that just does not know how to treat Mac users. That said, I'm giving 5 stars here because despite Razer's own website not having this app properly displayed, once I got it from here I was off and running. if I have any criticism, it's that Razer needs to hire someone to re-design their website and make it WAY more current and browsable on the support front. For a company that makes brilliant devices they are shooting themselves in the foot for a lack of web talent and investment.
**Note: If you install the older Mamba drivers, they appeared as a system Preference panel. This is what I did first, and I couldn't change any of the controls because it would not even recognize the ouse was plugged in!! This download is a standalone app. that does the job for the 2012 mouse.**
Once I had installed and re-started, I got the full use of my mouse, control of the colours on my scroll wheel and charge stand, and could happily program macros and profiles until I was blue in the face. I got my Mamba on sale for $100 and do not regret having it one bit - especially since my mouse before this was a crappy Microsoft travel mouse. My right hand is in heaven!
Note to all: I see Razer is having some trouble updating things to work with Mac 10.8. However if the evidence of these updated control apps for Mac is anything to go by, they will probably have updates soon. I stay in the land of 10.6 but shall soon be graduating, and I'm looking forward to seeing these things accessible in a simple way. Also, if you are considering getting this mouse, and do any gaming at all, get the Razer Nostromo as well. It also has software which Razer also makes unhelpfully difficult to find, but not nearly so much as the Mamba software (which doesn't even appear on a list of Mac drivers on their site) and it is a macro-programing monster.
