I was going to install a new copy of El Capitan via my USB drive, but it turns out it's dead, it's been corrupted. I erased everything before that, so I'm stuck with the installation screen.

How can I download a new copy of El Capitan? As you know, Safari comes preinstalled. I also have a Windows computer, so I'm open to suggestions.

Here's my Macbook Air Model: MacBook Air "Core i5" 1.4 13" (Early 2014)

  • A direct download link exists for an El-Cap.pkg (not the OSX installer.app!) but it has to be verified and hacked on a second Mac. Please add your mac model (e.g. MacBook Pro early 2011). – klanomath Jan 10 '17 at 16:12
  • @fsb, I tried that, but unfortunately Safari doesn't connect to mac app store. It says that it can't open urls that start with "macappstores:" – salep Jan 10 '17 at 16:15
  • Simply boot to Internet Recovery Mode (alt-cmd-R) and install the original system (Mavericks). Then - after installing and configuring Mav - download El Cap. – klanomath Jan 10 '17 at 16:17
  • @salep, I'm the author of the question that fsb linked in his comment (and also wrote the answer) and I can tell you having just tested it again, it works just fine! – user3439894 Jan 10 '17 at 16:22

You can't really download the OS X El Capitan installer app without the App Store.app easily. You can download the raw (unverified) pkg installer though, but to verify it and convert it to a legit OS X Installer.app App Store.app and a newer OS X system is required again. So simply downloading it on a Windows system won't help.

To solve your problem simply boot your MacBook Air to Internet Recovery Mode by holding altcmdR after turning it on.

In the OS X Utility window choose "Reinstall OS X" (or similar) which will download and install the original OS X your Mac came with (10.9 Mavericks).

After configuring your system open App Store.app and download OS X El Capitan. If you haven't purchased it previously use the answer in How to download OS X El Capitan from the App Store even if never downloaded before macOS Sierra was released or purchased is grayed out.
