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.
