I’m stuck turning an Apple MDM .csr file into the required .pem file. I’m doing the conversion inside Keychain Access on macOS, but every attempt ends with the “Certificate conversion failed” message. What I need from you: walk me through – or remotely perform – the correct steps to generate a valid .pem file from my existing .csr, verify the result, and explain any tweaks (OpenSSL commands, Keychain settings, file-permission changes, etc.) so I can repeat the process on my own next time. Deliverable • A working .pem file derived from my provided .csr • A concise set of repeatable instructions outlining what you did and why, so I can update future MDM push certificates without hitting the same roadblock.
I’m finalising an MDM solution and the last step is converting my certificate signing request into the .pem file the system expects. On macOS I create the .csr with a GUI app, yet when ...GUI app, yet when I feed that file into the conversion process I consistently get “File access denied”. I need you to: • diagnose why this particular .csr is being rejected, • successfully generate the required .pem, and • show me the repeatable steps (or correct settings/permissions) so I can recreate the file myself when the certificate renews. If you prefer using Terminal-based OpenSSL or have another reliable workflow, that’s fine as long as the end result is a valid .pem that my MDM server accepts. Quick turnaround is appreciated; as soon as t...
