I realize this is an old thread, I had never experienced this issue before I updated my old Windows 7 box to Windows 10. - I do not know if that has anything to do with it, but I never had to double check if a rapidgator download completed or not, once the download started I could pretty much bank on it completing, and I have downloaded at least 1,000 movies from them, likely 2000 or more but I use several hosts and don't really keep score, they do seem to be the most common host for most of the stuff I grab. I will try later on with a mac and see if there is any difference, but I never used mac with them before so I won't have a reference point. There do seem to be some files that fail every damn time, and others that I can get after a few tries so maybe they have some intermittent server issues or some nodes in their cluster that aren't well maintained/failing. That said I would be interested to know if anyone out there is able to succesfully download this file:
