Can't resume downloading El Capitan from my progress when disconnected
Having problems downloading El Capitan for days. My connection keeps disconnecting and I keep getting this annoying message, "Failed to download, Use Purchases page to try again". Whenever that happens, I start over instead of resuming where I left off or from my current progress. I was already halfway through the download when it happened again. What do I do? How can I prevent this from happening so I can resume my download from the exact progress it has stopped?
