Need to reinstall system help

My local thrift shop got a Mac donated, but there is a password to get into the machine. Is there a way that I can put a new operating system on this machine and bypass the password? Any assistance appreciated, they could really use a working machine.

Depending on the OSX version, sometimes you need an install disc. http://lifehacker.com/5681710/how-to-bre...ing-to-you

Depends on if it is asking for an iCloud password or just a user account. If it is just a user account password then you can hold down option and see if there is a recovery partition. If not, you will need to find out what model the Mac is and what OS it can take. Then download that and make a CD or thumb drive to install.

You should be able to boot in Target mode - hold T at Startup sound. Connect it by FW to another Mac. At that point you can erase the donated drive and install any OS equal to or newer that the one it came with.

It's not so easy if the system is protected by a firmware password:
