Trying to complete my set of Intel-based OS X systems. Apparently I've lost a few along the years, moving from drive to drive. Does anyone know where these are available for download:
· OS X 10.8 Mountain Lion
· OS X 10.9 Mavericks
· OS 10.10 Yosemite
· macOS 10.12 Sierra
I might or might not make a multi-boot setup on my MacBook Air…
