Hi @fcbogle
Welcome to the Posit Community Forum.

You require an R version >= 3.6 to install readxl. Better still, upgrade to the latest version 4.3.1

This message typically sometimes indicates a connectivity issue. But this looks like it is looking in a non-existent directory, for mavericks version of macOS, which rstudio no longer supports (policy is current version and previous two). Updating to Big Sur macOS (perferably Ventura) should fix this.

• R Version: 3.3.3

Staying on this version will create mounting issues with the passage of time. I strongly recommend installing the current version from cran-rproject.org unless you have a specific need for this very old (2017) version.

Thank you, I upgraded to latest version and all good.
