Hi Uchenna, Thank you for your help, Actually I bought a 2nd hand M2 Macbook Air and the seller never mentionned the MDM issue. When I try the 1st Method, the Ventura Install didn't want to continue the install without Internet due to the MDM and after the Mac erase and activation. Now, is there a way to get rid of the Security profiles ? After Method #2, here's what I get : Error fetching Device Enrollment configuration: (34000) Error Domain=McCloudConfigurationErrorDomain Code=34000 "The device failed to requ est configuration from the cloud." UserInfo-(NSLocalizedDescription=The device failed to request configuration from the cloud.,CloudConfigurationErrorType=CloudConfigurationFatalError} Is it Ok in your opinion ? Thank you again for your advice
