Hackers locked the machine how can I unlock it
This was my moms machine. She purchased it used and being 81 and not knowing what she was doing started having issues. A hacker called her said they were from apple and locked the machine when she said she would not pay them. Well I unlocked it the first time, but this time yes a second time, it appears that the recovery hd Has been removed. I made a flash drive from my windows laptop for the OS X recovery but cannot get into the machine to download it in. What or how do I do this? HELP PLEASE!
