Hey guys, I'm hoping someone can help me out. I have a mac air and using sierra 10.13.4. I have done all the steps but I'm stuck on step 6 and beyond. I have already downloaded the patch and extracted the file but this is what I keep getting when I double click Rub Patch Rs. Anything know what I should do? I took a screen shot so you can see what I'm talking about. Thank you in advance! I believe I figured it out. I tried deleting the post but I'm not sure how. Sorry!
