Lately I have been getting a top-of-the-page warning when I browse Flickr too fast. (And once I was bumped off Flickr entirely.) In the not-too-distant past, the computer would get bogged down and that was the only warning. Clearly, I don't want to leave Flickr. What are the options? I am using Big Sur on my MacPro (Late 2013), which has 16 GB of memory.
