At work I use an iMac which I'm going to have to reset to factory settings after my job ends. Since I only have access to slow, unstable internet, I thought it might save some time to download the El Capitan installer from the App Store in advance and create a bootable installer drive, rather than using internet recovery.
After I (erase the drive and) use the bootable installer to reinstall the operating system, will the resulting installation be associated with my Apple ID in any way? Or more generally, will it have any personal information associated with me? I'd like to leave a completely fresh, un-personalized installation of OS X for whoever is going to use the computer next.
