As always, you can make yourself a dandy boot disk or USB drive by opening the installer's app bundle, and writing the following file to your favourite medium using the "restore" tab in Disk Utility.
/Install OS X Mavericks.app/Contents/SharedSupport/InstallESD.dmg
- dimillian 13y agoWhen you install/update the system it creates/update your restore partition. Does Apple still only put necessary file and then do an over the air installation or they put the whole system ready to install ?
- nwh 13y agoI'm not sure yet. For 10.9 the installer put all the necessary files in, and didn't download anything over the air for me.
- kevinxucs 13y agoCompared to which version? I think every version of OS X installer downloads all files before installation.
- Groxx 13y agoWhen installing from one of the upgrade-apps or their bootable USB counterparts it installs the whole thing from the disk, nothing downloaded. The download step is basically just for reinstalling w/o an installer.
- kevinxucs 13y agoNot any more. Needs a bit more work than that.
- rietta 13y agoCopying that file to an external and burning a DL DVD backup of that image were the first steps that I took after finishing the download.
- benguild 13y agoCheck the Mac Rumors forums before doing this. I heard that this approach doesn't work anymore because Apple changed some dependencies.
- uxp 13y agoI think you might be correct. Apple used to distribute the Lion Recovery app, which basically copied the InstallESD.dmg to a USB stick, but it no longer works with Mountain Lion. Running this command, however, uses a hidden executable inside the installer application to write itself to a USB stick. sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/USBSTICK --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction NOTE: This uses sudo because it needs permission to write to the device. It also has the potential of destroying external drives, internal drives and boot drives. Please change the value for the 'volume' flag to point to the mounted path of the USB stick or SD card you wish to use as the bootable install disk. It will overwrite all the data on that disk. I am not responsible for any data loss using this command. Please double check all paths, all commands and all flags before running this.
- derefr 13y agoWhat happens when you do that without the --nointeraction flag? Presumably, it explains what it's going to do, and prompts for elevation?
