How to view the Home/Library file on an external drive? Im running OSX 10.13.6 and I have an external drive in an enclosure that was originally an internal drive of my previous computer running 10.12.

I need to retrieve a file from the /Library external drive, so i go to /Volumes/External Drive/Users/Sam/ but /Library folder. Any ideas ? 

Normally i would just to finder > Go and hit the option key, but this only works for a locally Home/Library not a remote Home/Library.
When looking at the home folder where the Library folder would be, toggle ‘Show hidden files’ with shift-cmd-. then the Library folder (and other hidden files) will be shown.
