The new Mac Tahoe OS has a weird bug as well.

The wallpaper extention copies the image/video you want to use into a cache and, if you have a wallpaper that changes, it caches every single image you use. If you're drawing from a folder that has 100GB worth of images, it will cache 100GB worth of images...and fill up your hard drive. I was drawing from a folder that has 400GB of images, and it was crashing apps because the cache was taking up all my disk space.

I've had to stop rotating my wallpaper and go with something really simple, and i really miss being able to use all my images.
