Hi, 3 weeks ago I had a little issue with my battery, it disconnected and during operation shut my whole comp down, upon opening the mac again, I had to use DISK WARIOR to restore files, not pretty, luckily I got in but as a new user, so could only access my files through cmd/shft C and folders etc. I want to regain control of that account now, as it has important firefox tabs on there and tbh the newer account i set up as a temp is just so slow compared, I have 16gb it should not be this slow. Here's my spec. mac pro 2011 500gb 16gb 10.7.? I head if you just set up a new user with the same name the log in that is all you need to do, well this did not work for me sadly. It says 'user already in use" but I can not see it anywhere. Anyone have any ideas please? Thanks.
