How to prepare (old) Mac for selling/donating?
I have a 13-year-old Macbook with Lion 10.7.5 that I want to give away or sell. I've removed all my files, but now need to totally wipe the memory.
I've seen various threads on doing this, but most are for newer Macs or super technical. I also don't have any OS install disk.
What next steps should I take?
