How to force a readonly volume to remount as read-write?
I have to do the following from the command line to get a USB drive to mount read/write:

diskutil list
sudo diskutil unmount /dev/disk2s1 &lt;- (put your volume/partition in here)
cd /Volumes
sudo mkdir &lt;FOLDER_NAME&gt;
sudo mount -w -t msdos /dev/disk2s1 /Volumes/&lt;FOLDER_NAME&gt;


This is with a FAT32 formatted USB stick. Not sure why, but my Mac will only mount these read only when they automount, only started happening recently. Reformatting does not resolve it, even formatting in a macOS native filesystem gives me the same issue. This is happening on multiple USB sticks after many reformats and reboots.

The problem is that I have to do that each time I remove the drive and want to plug it back in.
