Hi, As far as I know, that style file is part of the standard MacTeX distribution, which is built upon TeX Live, and includes the blkarray package by default. I have it installed on my MacBook and did not do anything other than a default install of the full MacTeX release:
% find /usr/local -name blkarray.sty /usr/local/texlive/2025/texmf-dist/tex/latex/blkarray/blkarray.sty As Peter notes, I suspect that this is an issue on CRAN and would defer to Simon's interaction here. Also, as an FYI to Peter, I note below from the file path that you have TeX Live 2024 installed. The distributions are updated annually, and 2025 was released this past spring (March/April time frame). I do not believe that a prior year distribution is maintained for updates once the current year distribution is released, even though you can have multiple annual releases installed in parallel.
