Have just bought a MacBook Air and I'm getting blocked at every turn when trying to set up an Apple Account. Years ago I had a Mac I used for work and I believe I would have had an Apple ID then. When trying to set it up it tells me my email is already used so maybe I have forgotten what the old account was called. I thought it would just be a case of setting up a new account but I've tried everything. A bit complicated I know but there must be some way of fixing this. Maybe someone on here could help or lead me to an Apple help site, Thanks in advance for any help,.
