Ok, I give you a little bit context
I work at a University, writing my PhD. Both computers were given to me by the Administration and configured by "them". All the stuff in my old internal drive is in only one partition, at the beginning I did not know I would "accumulate" such a big amount of data and did not know that a partition would have made sense. I am in the Humanities Department, so we do not get that much "technical support" and the worst part is that the guy in charge of configuring the computers and then help us with technical problems hates Apple.... so every time I call him he just says it is a big mistake to have a MacBook and that I should toss it and buy me a new Windows Laptop myself...
At home I have a big WDMyCloudMirror with 4TB where I have the backup from my Mac and from the MacBook. I do not have a partition for backups and I don´t know if I can do that now, neither how to do it.
I do not want to make the same mistakes I made already with the old MacBook, I am really thankful for any suggestions and help.
Thanks again
