You have an extra right paren,
), somewhere in your init file. Here's one way to find it:
Start Emacs using
emacs -Q (no init file).
Visit this file - the one that Emacs was trying to load when it barfed:
C-x C-f /Users/user/.emacs
Comment out 1/2 of that file (roughly), using
If you get an error, then comment out half of uncommented part. If you didn't get an error, uncomment half of the commented part.
Repeat step 4 till you find the problem in your init file. This is a binary search: 1/2, 1/4, 1/8, 1/16, 1/32,...
If your init file is small, you might want to instead just look for the extra right paren directly. You might start at the file beginning and use
C-M-f to move past each sexp. Sooner or later you'll get to the one with an extra
As @NickD mentioned in a comment, here's another thing to try, and it's quick:
If you just byte-compile the file, the compiler should tell you where it sees the error (no guarantees that it will actually be there, but it doesn't hurt to check it first, before starting a binary search):
Compiling file /tmp/foo.el at Mon Nov 25 17:15:31 2019
foo.el:6:3:Error: Invalid read syntax: ")"
And as @phils mentions in another comment, unmatched parens can be found by using
which takes you directly to the culprit, so it is quicker.
