revoked 3 on mac

[the2the3the]

i'm attempting to root my evo with unrevoked 3, and my Mac (10.5.8) gave me this error message :"you can not use this version of reflash with this version of mac os x"
could anyone give me any reason for the issue and/or fixes?
thanks in advance

I don't know what 10.5.8 is but only Snow Leopard is supported.

It has to be 10.6 (Snow leopard) and above.
