[R-pkg-devel] Replicating CRAN M1mac checks

Hi all,

My latest submission is failing on CRAN M1mac:

https://www.stats.ox.ac.uk/pub/bdr/M1mac/CopernicusMarine.out

Having thought I fixed the issue, I resubmitted, but it is still failing on M1mac. My suspicion is that the M1mac machine is missing drivers to read the raster file used in the failing vignette. I would like to confirm my hypothesis before resubmitting. Is there a way to replicate the CRAN M1mac checks?

Closest I got was using rhub with macos-arm64, but it shows no problems:
https://github.com/pepijn-devries/CopernicusMarine/actions/runs/22064225101/job/63751799489

Or should I go ahead, avoid running the code in the vignette if drivers are missing and hope that this was the problem (with the risk that it will fail again at CRAN if it?s a different issue)?
Your thoughts are welcome.

Kind regards,

Pepijn
