<> = Prerequisites = If you are installing an older version of FSL (6.0.5.2 or older), please install [[http://xquartz.macosforge.org/landing/|XQuartz]] before continuing with the FSL installation. = Installation Video = We have created an [[https://www.youtube.com/watch?v=LgRZLev1LRw|installation video]] which gives an overview of the installation procedure on a Mac. <> = Checking the installation = <> = Migrating to zsh = Recent versions of macOS use `zsh` as the default terminal shell, whereas older versions used `bash`. If you installed FSL, and then upgraded macOS or changed your default shell to `zsh`, you will need to migrate your FSL configuration commands. See the [[FslInstallation/ShellSetup|Shell Setup]] page for more details. = Running the GUIs = To run a GUI version of a program you can either type its capitalised name with an additional '_gui' appended in the terminal (e.g. `Bet_gui`), or you can start the main FSL GUI by just typing `fsl`. If this doesn't work the see the [[FslInstallation/Faq|FAQ]] for how to go about fixing this, otherwise you are ready to run FSL. ---- = Advanced usage = <>
