# Deprovisioning ## How does deprovisioning work? As soon as a customer deletes a Mac device from his account, it is automatically moved into the so-called "Decomission" pool and then completely deleted via the MDM server using an [Erase](https://developer.apple.com/documentation/devicemanagement/erase_a_device) command. With this action (only possible via MDM) everything is completely deleted. Even the disk partition scheme and all including volumes are securely erased. Afterward, a fresh macOS installation is automatically initiated and then moved to the general "Available" pool. This cycle ensures that no residual information and data remains from the previous customer. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
