So that command does work?

Then you need the above command, not what you type here:
skatter <- read.csv(file="/Users/kama/Desktop/skatter.csv",
header=TRUE, sep=";")
But note that if sep=";" then you don't have a csv file and should
properly use read.table() instead.

That error means that R can't find the file where you told it to look.
Specifying the full and complete path as in your first example should
work.
If you're having problems with paths (which are a Mac issue and not at
all an R issue), you could also try
read.table(file.choose(), header=TRUE, sep=";")
I think that file.choose() should work on Mac.
The Intro to R document that came with R might also be of use.
