Last night my Macbook charger decided to give up on my and now it doesn't work anymore. i.e. Won't charge no matter what I try. So now I'm using my Ubuntu laptop. But I need to access some files on my Macbook so I thought I could use my Time Machine backups to do this, but when I tried to open the folder from my Time Machine HD it says I do not have permission to read it. Is there a way for me to get permissions to do this or am I stuck? Or does someone have the solution to my charger problem? I'll probably have to end up buying a new one anyway, but that won't happen for a day or two.
