New mac user. Help! Apple ID not working. Limit reached? How to change?
Hey Folks.
I just bought a used / mint MacBookPro. I'm a PC user and programmer by trade, but I'm done with MS. So, I'm doing ok, but I registered for a new Mac ID. The old one was the guy that used to own the MacBook pro, but I can't reach him, and I am having trouble doing updates because when I try to log in to the App store the window that pops up has the old uers creditionals / user id already inserted in the text box and it's grayed out so I can change it. Or, I get the message that Apple ID limit is reached. Anyway, I deleted him off the machine along with his files under the profiles or users. I now need to change the app store to use MY APPLE ID!
Please advise where to change if you would ?
Also, is there a link somewhere I can study the Mac Os online?
By the way, if it matters this laptop is Maverick .. The OS is. I hope that's enough info to get help. I really appreciate it in advance. I'll book mark this site, and see what answers I get later.
God speed and thanks again in advance
