I have 4700€ iMac (Retina 5K, 27-inch, 2019, 3,6 Ghz 8-Core Intel Core i9, 64 GH 2667 Mhz DDR4) and this Big Sur has made everything extremely SLOW!! :( Using finder and Preview-app in it is PAINFULLY SLOW!! And newest Photoshop 2021 also works very slow. This is big pain in the ***, I should be doing big photo edits to my customers etc. Apple, get yourself together!!!!! We are waiting for and update to fix these!!!
