Mac Password changed - need to know options.

Hello all,

Two things I will state off the start:
- not overly familiar with Macs and Macbooks and the like
- I am not sure what type of Mac we are dealing with here. I am assuming a relatively new Macbook (maybe pro).

My client is asking about her Mac at home. There is a 'household' issue of some sort, and the password has been changed. She either needs access to the contents directly or failing that, making a copy of the HDD in some way to possibly access the data off site or sometime in the future.

I know on a PC if I had physical access to the drive, I could at least gain access to the contents/data on the drive.

I realize I am being a bit vague here, but that's all I have right now.

Any helpful input appreciated.

Thanks.
