9 installers on a 128GB USB-A macOS bootable installer (includes from Tahoe back to High Sierra), no internet needed. All versions of macOS come from official Apple installers, perfect to upgrade your OS, software reinstallation, ability to format your internal drive / start with a clean install, or anyone wanting to have an emergency Mac boot disk in case problems occur down the road.
This USB and the instructions provided are all you need to install a new compatible MacOS onto your Mac computer. MacBook Pro, MacBook Air, iMac, MacPro, MacMini etc. Message me with any questions on compatibility. Internet not needed, it’s all self-contained and efficient.
