This question already has an answer here:
I don't have access to the Internet where I live and I must go to the public library to use it. Unfortunately, there is a 100 MB download limit and I must pause the download and reconnect each time. If I'm a few seconds too late, the El Capitan download automatically goes into the install program and I have to start the download all over again. I once got to 3 GB and lost it all. Is there any way I can recover the downloaded file when I connect to the Internet each time? I know it is there somewhere but the download process assumes that it has finished somehow and begins the install.
