Go back to my question macOS Earlier Operating Systems User profile for user: elevate29 elevate29 Author User level: Level 1 12 points OSX fresh install. Should I erase OS X Base System?

Hi, I'm trying to format and do a clean install on a 2012 MacBook Pro currently running Yosemite with a SSD. I've erased the HD but should i also erase the OS X base system before exiting DU? Can I then install a fresh OS such as High Sierra? Thanks

There is no need to erase The Base System. A new installation will over write it.

  • Macbook Pro Mid 2010. Erase and Reinstall OS X I've got a Macbook Pro Mid 2010 that I'm trying to wipe clean and do a fresh OS install on. When I started it in recovery mode and used disk utility to erase the disk, something went wrong and now all I can see is 'OS X Base System', which I can't partition, erase or restore. So I figured all I need to do now is go to 'Reinstall macOS' and install High Sierra. But when I do that and it asks me to select a disk to install to, there are no disks to select, there's just a blank space under the words 'select the disk where you want to install the macOS' What do I do? Hoping someone can help! 3095 3

Why do you think it is necessary for you to do a so called "clean" install on your MBP?

What problems are you having with it?

Unless you are having serious problems with it I suggest you simple install High Sierra.
