It IS the MacOS creating these files.
No, it isn't. It's easy to prove to yourself that it isn't: Load up a usb drive with music files on a mac. Then look at that drive either with Path Finder, or with hidden files made visible in finder by using "
defaults write com.apple.finder AppleShowAllFiles YES" in the terminal. See all the hidden files? No, because there aren't any besides the .ds_Store one. Then take that drive over to a windows machine, and load it, check for hidden files - same thing, there aren't any. Then, take that drive and play it in your taurus or whatever, and then look for the hidden files on either computer - there they are! So, where did they come from? Not from the mac, that's for sure.
Then how do you explain why there are
so many conversations about how to remove these files and prevent them from being created? I've been working on Macs long enough to know what they do.
This is really apples and oranges. The mac isn't creating hidden files that impede the model 3 audio system in any way, and the OS the tesla uses (linux) also doesn't create hidden files, so I don't know why you've gone off on this tangent anyway. This is a thread about how how to format and partition a drive for music and dashcam/sentry use, I don't see how your argument about nonexistent hidden files has anything to do with it.
Here's a constructive suggestion - get a USB drive of some sort. Flash drive, SD card and reader, ssd drive, it doesn't matter. Follow the instructions from the first post in this thread, and then put some music files on the music partition, and set up dashcam to use the other one. See how it works. If you do it right, it'll work fine, you won't even have to worry about hidden files, imaginary or not. From the FWIW department - I use a sandisk extreme SSD, and have the music partition formatted as ext4, which is the native format the tesla file system uses, which works a bit faster than fat32 for music. I also use a mac to transfer music back and forth between this drive and my computer, and even checked it for hidden files today earlier (there weren't any).
Edit: if you're still paranoid about the scary hidden files, you can eliminate them easily for removeable devices on a mac by using Eject for Windows -
Eject for Windows - I use this for programming ARM devices that use embedded memory that don't get along well with DS_Store files and such. I've never bothered using it for tesla music drives as they work fine without it.
