CPU at 584% with Bridge. Impossible to work

Hello, how much free space do you have on your disk?

How large is the folder Bridge currently looks at?

Is it showing subfolders?

What kind of files are there?

Did you try to reset Bridge preferences? (Hold down CMD+OPT+Shift as you click on its icon to load it.)

HI Francesco,

We have pretty much the same configuration with the exception that my iMac is 2015 and that I'm on Mojave. I am pretty sure the former is irrelavant while the latter may be very significant. When Catalina was released there were announcements all over the wazoo from Adobe and others about how it's best to let things settle out with Catalina and not be "firsters." Obviously that's almost impossible to get to everyone and you might have been one who didn't get the message.

There is one member here, 007jm, who said he found a series of things to do during the upgrade that let him avoid any problems, hopefully he'll catch this and respond if there's anything that you can do. Otherwise, you might have to revert back to Mojave until things are cleared out. 

I wish you the best and good luck!
