Peugeot updates on OSX
Preparation of updates for Peugeot cars is supported on OSX, but will fail consistently because OSX adds metadata folders and files to the update sub-folders causing a checksum failure on the car.
The following commands, ran after a new version of the software or maps has been downloaded and before plugging the stick in the car reliably solved the issue for me:
sudo mdutil -X /Volumes/NEW
sudo mdutil -i off /Volumes/NEW
cd /Volumes/NEW
sudo rm -rf System\ Volume\ Information
sudo find . -name "._*" -delete
sudo rm -rf .fseventsd
sudo rm -rf .Spotlight-V100
sudo find . -name ".DS_Store" -delete
BTW, the Peugeot update app is still an Intel app which means it will stop working soon.
