Old Apple ID, Can Not Update software
My boss gave me my Macbook Pro when I quit. I need to update my pages, notebook, and numbers apps but it keep pulling up his apple ID and wanting his password. Am not going to call him. I have already logged into my apple ID account but it stills pulls up his. How do I get him off of here.
MacBook Pro, OS X Yosemite (10.10.4)
