Hello, I am using an intel mac mini from late 2012 for umbrel. I tried to delete the app and restart de node sync some times but I have always the same problem that the node stucks synchronizing about 38%, 60% or 80%.

I do not have a good level with ssh, but I someone can help me explaining with all the details (commands) not abbreviating obvious parts of the commands, I can do whatever you tell me.
Thank you very much
