I have a developers account and need to install macOS on 2 devices, but keep getting message thet redemption code has been used. How do I get around installing on 2 devices?
do you need multiple redemption codes when installing macOS on two devices?
You can either redownload via purchases tab on each machine - or to avoid having to redownload just make a bootable usb and use that on each machine
To make a bootable usb format an 8 GB (or preferably 16GB) USB3 drive which should be called Untitled and formatted as Mac OS Extended (Journaled). The installer should be called Install 10.12 Developer Preview.app and should be in your Applications folder.
Run this in terminal and wait about 20 minutes:
sudo /Applications/Install\ 10.12\ Developer\ Preview.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ 10.12\ Developer\ Preview.app --nointeraction
