Can you give us all the output that you get from when you do

install.packages("dplyr")

Please copy the code and paste it here between

```

```

It will be properly formatted and much easier to read.

install.packages("dplyr")

It looks like {dplyr} is correctly installed but I am not a Mac user.

Try this again and we will see what happens

library(dplyr)
