You are getting the whole DMG as handed over to us by Apple technician Managers. This is an untouched copy and you can use freely every application included after completing the installer. The certificates work and won’t invalidate for more than two years so you can install in the future as well. Take a look at the picture and if needed contact as about information for what each tool does.
Rest assured, if you purchase one of our Apple Service Accounts, you get the tools for free.
