[Need help with SAMI on Mac!]

I have installed SAMI exactly as I saw in a video on youtube explaining how it works. I followed the steps and installed the mod the same way as in the video yet for me there are no mods installed. When the game runs the car I replaced gets instead removed from the game i.e. cop car disappears. I have searched google for answers with no luck.

How do I install mods using SAMI, I have tried manually but I cant find the San Andreas user files in the finder.

is there any other program for Mac that will install mods successfully??

[San Andreas Modding Help Please ?]

same thing happens for me on Mac. I have watched youtube videos and it works for them but not for me. I have restarted my Mac after installing the mod which ends up not being installed. i have tried everything i can think of and nothing works.
