I cannot install mac os

Thanks for reaching out Lpacoo,

It sounds like you are trying to reinstall macOS through recovery mode on your MacBook Pro. We can help.

If you're getting an alert that tells you you're unable to contact the recovery servers, there are a few options you can try:

• Try again later and see if conditions improve, to rule out any service interruptions affecting the download.
• Try using a different Wi-Fi network, to rule out firewall or other network security settings from preventing the connection.
• Or, you can Create a bootable installer for macOS to use to install the macOS software instead.

Hope that helps.

Take care.
