100% confirmed working with 26.2 beta 2 (25C5037j) on MacBook Air M4 with 24GB RAM. I barely even let it boot I was so excited to check. Amazing! Thank you so much!

As a lifetime Windows only guy having my first Mac ever in my life after 35 years of running Windows (and hating Mac) Not only is it supreme in hardware and software, but never have I had a response from an actual engineer. Not to mention a helpful and clear response. Thank you sir, and for all your hard work.

Awesome. I don't know if this will help, but I seem to have resolved the problem on my M4Pro Mini running these two commands: # Quit apps that might use iCloud Drive osascript -e 'tell application "Finder" to quit' # Kill iCloud daemons killall bird cloudd fileproviderd # Remove local iCloud metadata cache (NOT your files) rm -rf ~/Library/Application\ Support/CloudDocs rm -rf ~/Library/Caches/CloudKit rm -rf ~/Library/Caches/com.apple.CloudDocs rm -rf ~/Library/Preferences/MobileMeAccounts.plist # Restart the system sudo shutdown -r now and this one: osascript -e 'tell application "Finder" to quit' killall fileproviderd bird cloudd # Move the offending FileProvider container aside mv ~/Library/Application\ Support/FileProvider/723EBBFF-303E-471D-924D-C7D140F50B49 \ ~/Library/Application\ Support/FileProvider/723EBBFF-303E-471D-924D-C7D140F50B49.old # Let macOS rebuild a fresh one on reboot sudo shutdown -r now The strange thing is, my Macbook Air the same commands didn't do anything. There were two instances where I resolved the lag on my Air. I removed a specific folder from the ROOT directory of my iCloud drive. Unfortunately the problem came back I then took everything out of my drive (including desktop and documents), made a backup of it. Then screen shared into my M4 Mini and from that backup, restored it to documents on my Mini. Even after the Air was done syncing, it was perfect for a little bit. Macbook Air, I deleted everything. Lag. Turned OFF desktop/documents. Lag. I hope this MAYBE helps.
