MacOS – standalone upgrade from older version to current version osx

mac-appstoremacossoftware-updateupgrade

I want a standalone upgrade from an older osx (10.7.4) to the current mavericks.

There is the free upgrade in the app store which normally would be perfect — but my internet connection at home is slow and spotty. The upgrade is 5GB in the store. I get about 1GB, and my connection drops, and now I have to start over.

So what I want to do is get a standalone way of doing the upgrade — this would allow me to use my other computer (faster connection) and sneakernet (use a USB stick) to transfer the file(s) to the Mac.

The combo and delta standalone updates you can get only apply within the same version.

Does anyone know of a way to do this standalone upgrade, even if I would have to apply multiple installs / updates / upgrades?

I suppose other solutions could include a multiple smaller file solution, or give the ability to resume the download from where it left off.

You could get the installer from wherever you have a decent connection, and then create a USB key with the installer.

Once you have downloaded the installer on any machine, see the quick instructions here:

Create a single GPT (GUID) partition on the USB key, and format it. Then run:

sudo "/Applications/Install OS X Mavericks.app/Contents/Resources/createinstallmedia" --volume /Volumes/untitled --applicationpath "/Applications/Install OS X Mavericks.app" --nointeraction

"/Volumes/untitled" is the mount point of your USB key. For the verbose version with pictures, see here.
