I attempt to install data.tables using the same approach: remove.packages('data.table') Now, I switch to one of my existing R Projects that have renv going on. When I load the package using library(data.table) (outside any project in RStudio), I get the following message data.table 1.14.3 IN DEVELOPMENT built 03:03:48 UTC root using 4 threads (see ?getDTthreads). Install.packages('data.table', type = 'source',

The actual installation step in R looks like this: remove.packages('data.table') I would like to get it working in a project that uses renv. Having installed the GNU Fortran complier from CRAN and following other steps in the instruction, I can get the proper installation in RStudio, when I work outside a project and do not use renv. Luckily, the developers of the data.table provide instructions on how to solve this issue. After several years of many reports of installation problems on Mac, it's time to gingerly point out that there have been no similar problems on Windows or Linux. Check for updates, and our Mac instructions here. Please engage with Apple and ask them for support. It should still work but in single-threaded mode. This installation of data.table has not detected OpenMP support. If one simply runs install.packages('data.table'), they will get the following message upon loading the library: data.table 1.14.2 using 1 threads (see ?getDTthreads). It is well-known that 'properly' installing data.table on Mac is challenging.
