Hardware recycling with Apple

[mhasman]

Hello,

Anybody use Apple Recycling Program for old macs disposal?

I am looking for some Recycling Program documentation which officially confirms the secured disposal, etc. Would you please direct me where I might find it? Appreciate that!

Thanks!

Always wipe your devices before you dispose of them, regardless of the recycling service you use.

That being said, Apple uses PowerON for their recycling. Here's what you're probably interested in:

@elliotjordan Thank you Elliot!

On the note of device wiping:

Unencrypted disk:

diskutil secureErase 1 /dev/[disk number]

Encrypted disk, just have to destroy the partition scheme:

diskutil cs delete [Core Storage UUID]

I have a script that finds the internal storage disk, checks if it's encrypted or not, and runs the applicable command from above. You could run this script in a netbooted OS to wipe computers being returned or recycled.

For bonus points you can put a Platypus GUI wrapper on the script and have it on the desktop of the netboot OS and it will show output of the script as it runs. Then anyone can help you wipe computers, or you can wipe a bunch easily because all you have to do is double click the app.

Please be careful with a disk erasing script. Use it at your own risk.

For lab computers that do not have sensitive data, can't we just run the WIPE command, in the JSS Management Panel?

[jesseshipley]

Just as a note on secure erasure, don't bother with SSDs. It doesn't do anything of value.

[Chris_Hafner]

@jesseshipley Thanks for pointing this out. I've been digging into TRIM ever since I saw your post. It seems that we're just missing a tool that really should be provided by Apple. The concept of a secure erase is quite simple and ultimately quick on an SSD with the proper utility.

That said, it looks like actually performing a "secure erase" or other types of multi-pass writes could potentially decrease the lifespan on an SSD. I'm simply posting this because I had no idea.

[jesseshipley]

@Chris_Hafner TRIM is provided by Apple. It was always enabled on all of their SSDs and support for third party was added in Yosemite. The best thing you can do these days, no matter the device, is make sure you enable FV2 when the machine is first provisioned. That way you can just do a regular erase when you are done and not have to worry about things.

[Chris_Hafner]

Thanks! @jesseshipley I had thought of that, but in our environment (BYOD, EDU) FV2 is a bit heavy handed for our students and temporary loaners. For our admins and the like, sure. I just wish I had a quick command that could be issues to flash the SSDs quickly and programmatically like the examples above.
