Hi everyone,
I wonder if anyone can help me solve an issue that's driving me mental. My Lightroom catalogue is saved on an external hard drive. However, when I import photos to Lightroom Classic, my Mac hard drive also seems to fill up and I cannot for the life of me work out why.
Is it the case that Lightroom is saving previews etc somewhere on my mac by default, even though my catalogue is saved to an external HD?
Thanks

The previews are saved in the same folder (well, actually in a subfolder of) the folder that contains your catalog file.
The photos are saved wherever you tell Lightroom Classic to save them when you import.
So, your task, confirm (rather than just say) that the catalog and previews are on an external drive, and not on the internal hard drive. Confirm (rather than just say) that your photos are saved on the external drive and not on the internal hard drive.

You haven't mentioned what size your internal disk is and how much space it has remaining, which can be helpful to those of use trying to provide help. Additionally, when LrC imports raw photos it creates cache files for use in the Develop module. By default, these are stored on your primary disk and the default size for the cache is 5GB (see atached screenshot). The location and size can be changed by the user, but don't reduce below 5GB. In some cases, users may have increased the cache size to improve performance. If you've done so, then reduce to 20GB or less.

Another thing to watch out for when importing is to make sure that the Make a Second Copy To option is either deselected, or if selected make sure it’s pointed to the folder you really want. If it’s always making second copies of all imports into a folder on your computer, that could be a reason you’re losing storage space.
