Ever since the upgrade to macOS Big Sur, Messages has been much less responsive with UI lag. It isn't as bad in Safari, but it seems to also be an issue there too. I have plenty of free SSD space, and it doesn't look like my CPU nor RAM usage is even close to being half fully utilized. Considering my MBP is not even 3 years old, this seems pretty wild. Am I alone here? Anyone have suggestions for a fix?
