When running low on storage, you can move all CrossOver bottles to an external SSD and keep your Mac's internal storage free.

1. Close CrossOver

Make sure CrossOver is completely closed.

2. Create a CrossOver Folder on the SSD

| Note that ssd is named storage

Example SSD mounted as:

/Volumes/storage

Create the destination folder:

mkdir -p "/Volumes/storage/CrossOver"

3. Move Existing Bottles

mv ~/Library/Application\ Support/CrossOver/Bottles \
 "/Volumes/storage/CrossOver/"

4. Create a Symbolic Link

ln -s "/Volumes/storage/CrossOver/Bottles" \
 ~/Library/Application\ Support/CrossOver/Bottles

5. Verify

ls -l ~/Library/Application\ Support/CrossOver

Expected output:

Bottles -> /Volumes/storage/CrossOver/Bottles

6. Confirm SSD Access

touch /Volumes/storage/test.txt

If no error appears, the SSD is writable.

Result

All existing and future CrossOver bottles will be stored on the SSD:

/Volumes/storage/CrossOver/Bottles

while CrossOver continues to use its normal path:

~/Library/Application Support/CrossOver/Bottles

thanks to the symbolic link.
