I'm contemplating downloading it but I'm in an area prone to connectivity outages. Or does it install a pre-loader which then downloads the actual disk image (which I can curl)?


App applications downloaded from the App Store will automatically resume if your network service is interrupted. The Lion download is a DVD sized .dmg file that contains the OS, not a pre-loader.

If your download does get interrupted you can control + click on the Lion icon in your dock then click resume.

    Unfortunately, experiences may vary... My flaky Internet connection disconnects every now and then for a couple of seconds (every 200-300 downloaded megabytes approximately), just enough to make the download fail. And, once every 2-3 times, the download starts from the beginning. – Remy Vanherweghem Jul 28 '11 at 21:11

    I had a similar issue: with Lion about 40% downloaded, I allowed Software Update to reboot the system to apply the SL 10.6.8 upgrade. When I logged back in, Lion started from 0%. :( – Ed Brannin Aug 6 '11 at 15:56
