To get around the problem, after the installer has downloaded, quit the installation routine and do not restart the machine. You download a 5 GB Mac OS X installer from the App Store, the machine restarts, your system is upgraded to Mac OS X Yosemite or El Capitan but wait, where has the installer disappeared? Your Mac, in a bid to save space, deletes the original installer automatically after the upgrade and thus you cannot reuse it on other machines.
Install Mac OS X Updates on Multiple Macs The Apple website says that “Apps from the Mac App Store may be used on any Macs that you own or control for your personal use.” This is however easier said than done. It will not just take too much time but you may end up consuming your monthly download bandwidth.Ī simple and obvious workaround to the problem is that you download the installer files on one Mac machine and then transfer the downloaded apps to all your other systems through AirDrop or WiFi. The problem is compounded when you own multiple Mac computers and you need to upgrade them all to the latest OS X update. The same is true for Mac apps like iMovie or Microsoft Office that have massive installers. Mac OS X updates are huge with the installation files running into several gigabytes.
