Earlier today I was helping a colleague at work who couldn't login on a M1 Mac. After Googling a bit I started in recovery mode, opened the Terminal and typed resetpassword. After changing the password and reboot it wanted to activate - after a while we got "Failed to create activation request".
I Googled some more and now I have removed the Mac from my colleagues Apple ID but we still get the same error. Does anyone know what's best to do next? Is it possible to save the data in any way?
@jonros Does your corporate network perform any SSL inspection on traffic going through your firewall? If so that may be interfering with communication between that Mac and Apple's activation servers. This is the document that lists all of Apple severs that need to be exempted from SSL inspection: https://support.apple.com/en-us/HT210060
@jonros Have you tried booting that Mac into Target Disk Mode: https://support.apple.com/guide/mac-help/transfer-files-mac-computers-target-disk-mode-mchlp1443/mac
That you've reset the password might prevent that from working, and if you have FileVault enabled the odds of being able to recover anything from that drive are low.
