When 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.
