Yeah. I have heard that Mac doesn't transfer the appropriate file names. Ok then if you can't download it from your phone, you can PM your gmail address to me and I can send you the apk directly if you want.(Don't worry, I'm not a spammer)
Otherwise, I'm not sure how else to get it to you.
In astro when you go into the zip(since you transfered the whole zip) the apk file should be in there
Ahh I was finally able to download it right to my phone. I guess the browser I was using was the problem, now I just go to language and keyboard to make it my default right?
