Hi guys. Just bought my first MacBook after 20+ years on PCs. I had a couple of drinks and stupidly decided to set up my new MacBook. It asked me for so many passwords and wouldn't accept many that I use all the time. Now I'm wishing I had used different passwords. I don't even know what apps/programs were requiring passwords, but it was at least 4 or 5 passwords. I'm wondering if I might be better off just doing a restore to factory settings and start over. Is that easy to do? Is it in any way harmful? Thanks for any advice!
