High Sierra Finder freeze naming/moving files remotely on a PC

Hi guys!

I recently upgraded my 27” iMac (Spring-2017 model) to High Sierra 10.3.2, from Sierra 10.12.6

And now I’m suffering a problem that never suffered before.

I usually work doing 3D animations, working on my Mac and then copying the files to a Dell-PC to render the project there.

All was fine with Sierra. But since the upgrade to High Sierra and connect to my PC (using a SMB connection), when I’m copying files from Mac to PC, or changing names (on the PC from the Mac), or moving / changing directories (everytime on the PC from the Mac) I unexpectly have a complete freeze on my Mac Finder. 3 times today. One more time yesterday.

It’s a “fatal freeze”. No matter I try to restart my Finder (using CMD-OPT-ESC) this does not work: the Finder completely goes away and even if I can open other apps in my Mac, the Finder no more appears.

And the only thing I can do is to force a shutdown, using the backside button. I even tried to shut down using Terminal (sudo shutdown -h now) without luck.

I saw some related posts like this or this, what points that maybe I’m not alone on this.

Any ideas?

One more detail: when moving files between my iMac and the PC, sometimes I use the Finder, manually, and sometimes I use a third-part utility (GoodSync). With this app al also have problems: doing the “analyze-directories” operation, no problem. But once I press the “Syncronize button… bang! The same story, which ends with a hard-shutdown :-(

Thanks for your feedback! :-)
