Used to Windows where this is easily turned on/off. On Mac, guess they’re trying to protect me from myself ;)
Anyhow, here’s a useful post that shows one how to accomplish this task.
To summarize, in case the post disappears. In terminal, enter ‘defaults write com.apple.finder AppleShowAllFiles -bool true’, then enter ‘killall Finder’. Finder should now show all hidden files.
If you want to hide the files again, change the ‘-bool true’ to ‘-bool false’.
