By • 6:00 am, September 21, 2012 • • The Mac App store provides a nice, simple, graphical way to keep your Mac updated with the latest software, letting you know when system updates as well as Apple and third-party apps have a new update to be downloaded and installed. If you don’t want to use the Mac App store, though, you can use the Terminal app along with some Terminal commands to do the same thing. When would you use this? Well, maybe when the Mac App store gets wonky, or if you’re not at the current Mac, and want to securely and remotely administer the Mac in question, that’s when. It’s fairly simple. This post is sponsored by MacPaw, maker of CleanMyMac Launch Terminal app from the Utilities folder, found in the Applications folder. Once launched, type or paste the following: sudo softwareupdate -l You’ll need to enter the admin password here to let softwareupdate do its thing, which is essentially listing all available software updates for the Mac you’re working on, remotely or locally.
If you want to install everything on the list, equivalent to clicking the Update All button in the Mac App store, type or paste the command below: sudo softwareupdate -i -a If you’d rather install only one update at a time, type the following, but replace AppName with the name from the list you saw in step one, above. Sudo softwareupdate -i AppName The caveat here is that the Terminal version of softwareupdate will only find and install system software updates, not third-party apps like the Mac App Store will. Of course, the Mac App Store can’t remotely update system software like this, either, so choose the tool best suited to your needs and specific tasks.
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 alt cmd R 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.
• If you hold down the option key and click the Purchased icon at the top of the App Store window, there's a good chance that the status button for the app in question will change from 'Downloaded' to 'Download,' or from 'Installed' to 'Install.' It's not a sure thing because Apple seems to leave it up to the app developer to decide whether or not to support optional downloads. • Another method that sometimes works is to option-click the 'Installed' or 'Downloaded' button. When this works, the download process will start right up.
