Hi, Thank you for coordinating all this!
I participated today (2/12/18) and my co-worker Will witnessed the entire process. Our response is: c13af4d4 477f66e7 53f25d51 1b6c4624 9f20f79a f63c20d8 c64e34c9 df90441b 0bf89ae2 8c05d71c 4ae9cb82 e0a3aa4d 41e99666 c54261a9 b0b75f6a 5c455436 Procedure: 1. We got a loaner MacBook Air from our employer. These machines are wiped before every use. 2.

We used a USB drive to copy the response file and we manually re-installed the OS once we were done. We returned the laptop so it can be wiped again. Finally, we published our response hash on our social media accounts. Alok
