I haven't figured out why, but once in a while, LR will change the path I usually use to import my photos to a specific hard drive. What can I do to make sure it always goes to one place and one place only? As an example, I import the photos from my SD card and copy them to a local hard drive. I almost never change this but occasionally the upper right corner of the import page will show that it has reverted to my pictures folder on my Mac, which I never want.
Any ideas why it changes?
The pictures folder is Lightroom's default location when using the Import 'Copy' method. You can save an Import Preset and use that every time you import. You will find the option at the very bottom of the Import window.
