Hi chaps, I have an iMac, iPad and iPhone and have just acquired a used MacBook Air, plugged it in and it’s now full of all the junk off my iMac including all the stuff on the desktop and applications that I never use. I had intended to try and keep this machine clean and use it for photography (simple post production) I guess the basics would be useful like email, safari, contacts … so my question… can I wipe it clean and start again without iCloud loading everything on it (I don’t need the kitchen sink).
