Hello,
Same problem for me :
MacBook Pro (Retina, 15 pouces, fin 2013)
2,3 GHz Intel Core i7 quatre cœurs
16 Go 1600 MHz DDR3
NVIDIA GeForce GT 750M 2 Go
Intel Iris Pro 1536 Mo
Behaviour: When using the finder, the **** freezes for a few seconds (about 10 seconds) and a rainbow wheel turns. I then find my hand on the **** again.
This also happens when navigating in a directory with several files (pagination).
Finally, the launching of several applications is very bad (VLC, finder, preview).
Conclusion: if you need feedback, please contact me, developers.
For information, I was in the beta of Big Sur on this same mac.
