I'm getting slightly different random numbers depending on the OS (Mac vs Linux):
set.seed(890458, kind="Mersenne-Twister", normal.kind="Inversion")
print(rlnorm(1504)[1504], digits=22)
sessionInfo()
Linux:
> set.seed(890458, kind="Mersenne-Twister", normal.kind="Inversion")
> print(rlnorm(1504)[1504], digits=22)

Is this expected? Is there anyway to guarantee reproducibility across platforms? It also happens with rnorm rather than rlnorm but with higher numbers.
