Clean Install?

[vito]

Is it possible to do a clean install during Mavericks setup?

Will I have to create a USB bootable drive to achieve this?

Current system is a rMBP ML

Thanks,

If you want to wipe your disk and reinstall the OS, then you have to have the OS installer on some other volume.
This can be the Recovery Partition (which gets updated after you've already installed 10.9!!); or some USB drive with the disk image from the downloaded app.

However, for most cases, a clean install is unnecessary, and any benefits that it might provide can be met using other, quicker less extreme methods.
What are you hoping to achieve?

No need to do a clean install.
Years ago it was the most prudent thing to do but Apple have made adjustments to the architecture. It's a lot smoother now.
Just upgrade. You'll have no regrets.

I am Mac owner since 1989. As a regular procedure, Clean Install has never been "the prudent thing to do." I have more fingers than I have Clean Installs.

You are describing Clean Install as Preventative Maintenance. No. A Clean Install is a radical procedure that is intended as solution to an intractable problem. An OS upgrade is not an intractable problem.

I've been a Mac user since 2011 and I agree.
