If you don't happen to have an external hard drive handy, moving the installer out of the Applications folder should stop it from deleting itself once it's done upgrading your Mac. The installer can be copied like any other file or application - just drag it to the target disk.


If you're upgrading multiple Macs with Yosemite, make sure to copy the installer to an external hard drive or a USB thumbdrive so you don't have to download it again.

That's a great way to save hard drive space. That installer measures several gigabytes, and will automatically delete itself after installation as part of its own housecleaning process. That's something you'll only find in most 2012 or later era machines.ĭownloading Yosemite will deposit the installer inside your Applications folder. Certain features like Handoff and Instant Hotspot only work on Macs equipped with Bluetooth 4.0, or Bluetooth LE.
