Finder is extremely slow in Mac M1

Hi. I run the EtreCheck, but it said that there is nothing wrong in my computer.

That's not what it does. It just shows the current status of everything on your Mac. Reviewing all of those details might give a clue as to why you are having a problem nobody else seems to have.

Did you migrate over from an old mac recently? I found that I had issues too and had to rebuild the spotlight index, which took a long time to complete (days), but when it did it was all good.

I've been using an M1 Mini for over a year and don't see anything slow down.

I zipped a 330MB folder and it took a few seconds. It unzipped almost instantly.

If you are copying to the same volume on your startup drive, it should be instantaneous as it would be using copy-on-write. The copy is just a reference until you edit it. At that point it copies to a new storage location.

Are you moving and copying to an external drive? What format is the drive and how is it connected? If USB3, are you really getting USB3 from the connection? Some hubs will downgrade the entire bus to USB2 if there are any USB2 or USB1 devices connected.

You can view that in System Information (hold option key when selecting Apple menu). Select USB and look for the bus your drive is connected. Does it show Up to 5Gb/s or 480Mb/s?

It does happen in the background with no indication of progress, and can take a long time if there are externally hosted files

Have you installed any 3rd party "cleaners", virus apps, VPN etc? An EtreCheck report might be helpful:

Are the files downloaded or in the cloud only? That would require downloading the files before copying or zip/unzip.

Just to mention it once again, posting an EtreCheck report could be useful.

See the above question about files in the cloud. Using iCloud does not imply that they are only in the cloud.
