Selling the MacBook on craigslist. Of course I agree to meet the buyer at the end of the day. Agrees to asking price. So I go to erase/wipe/re-install everything. Of course things don't go as planned. I should've wiped the laptop before putting it up for sale. Why do I make life so hard. Anyways. I've done this at least 20 times before...so not sure why it's not working on this one. But I have not made my own bootable disk before. I always had the USB drive from Apple. I wiped everything. - Erased from Disk Utility (I think it was) I downloaded El Capitan. 8GB USB drive for the new image. Command C - doesn't find bootable disks Commend R - sees my WiFi but does NOT connect with my password. (I know 100% what my password is and tried on other devices.) Can't get pass that. Tried connecting to an open connection but doesn't look to be strong and get a -1006f error. Commend Option R - leads me to same location Option - shows 2 partitions on another harddrive with the same install OSX El Capitan file but when I select the partition, it doesn't move/recognize my clicks/enters and then shows me a Blinky Question mark Folder. [?] Questions: USB bootable disk. I used Diskmaker X and it seemed to mount correctly. Showed the install files in the USB folder. If I simply drag/drog the Installer onto a USB / External HDD - will it function as needed? Do I need to update all of those lines that some instructional sites have? Seems a bit messy. I've read the "Blinky Question mark Folder" - means the laptop's HDD is shot - but I doubt it considering I was just using it 1 hour ago. Last thing I want to do is buy a new SSD to install. But I may have to. On second thought, a shot SSD may be the better news. Any thoughts. I seemed to be at a hairpulling dead end.
