+###### Mac OS X

+If you're using RStudio on a Mac, you will likely need to tell R Studio where to find cargo (the Rust package manager) by adding it to your path. You can do this by following the instructions below:
+1. Open your `.Rprofile` file in your home directory (you may need to press Command + Shift + period to reveal hidden files).
+2. Add `Sys.setenv(PATH = paste0("/Users/<user>/.cargo/bin:", Sys.getenv("PATH")))`, replacing <user> with your username. This will append Cargo to your path when you open RStudio.
+3. Save your `.Rprofile` file and restart R Studio.
+4. Install Entab from GitHub.

To install the ThermoRawFileParser, follow the instructions [here](https://github.com/compomics/ThermoRawFileParser). If you are running Linux or Mac OS X, you will also need to install mono, following the instructions provided at the link.
