Install macOS Sierra operateing a newer Mac to be deployed on an older Mac?
Any problem with using a newer Mac laptop to install macOS Sierra onto an external hard drive, then install into an older Mac laptop? (assuming both Macs are Sierra-capable, obviously)
Are there any issues with booting and running an older Mac from a macOS created with a newer Mac? For example, does the Sierra installer install drivers specific to the Mac on which the Sierra installer app ran?
