So my old company let me keep my labmac, Mac pro with windows vista buisness installed on it. I haven't used it in about a year and have forgotten the password. The company doesn't keep track of old employees passwords after 3 months. 

I have tried everything I can think of including the windows recovery trick to change pressing shift 5 times to cmd but I have no windows recover pop up no matter what I try.

I have no access to bios or anything that I can locate pressing all function keys. Here are the screens I can see with function keys.

 

 


I forgot to add that I have made an iso flash drive so I can try and format the computer but I have no way to change the boot options

If you hold the "C" key during boot does it give a boot menu to select boot device when a flash drive is attached? 

 

I am not sure this will work on a Mac but download the iso for NT offline registry editor here. Use the iso with Rufus to create a bootable USB flash drive. Attach the drive and press "C" at boot. Follow this guide to enable the hidden Administrator Account.

 

Once the Hidden Administrator Account is enabled you can access the password account or change its password.

 

Here is a video showing the procedure.

 

See this page on accessing EFI settings.

so pressing "c" didn't do anything for me, the only screens I can get to come up are f2 which shows only windows vista as the boot option, f8 which allows safe mode and such and the last one if f10 which shows the screen in the picture which I linked in this comment.

which is edit boot options.

Can you access BIOS/EFI by pressing the Option key at boot?

Looks like that is the trick, turns out Bio's has a password on it too >.<

From what I have read, the only way to clear a MacBook Pro password for the EFI is by removing a hardware chip and reprogramming.
