Finder getting slower

My Finder is "getting tired" after 4-6 minutes of extensive use. I mean it takes a second or two to open a small image in Quick View, the waiting circle appears. The rest of the apps are working well at all times. When I relaunch or force exit Finder, it gets normal again, but only for another 5 mins of extensive use. My RAM is 16GB, Activity Monitor doesn't show an overload. Please advise.

iMac 27″, macOS 10.13

Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes.


Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.

Pastebin is a good place to paste the whole report if you capture the URL while there…

Whew, they've changed pastebin & made it harder, but after pasting in, click Create new paste button, then Embed button, then copy the URL...

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck. In a Reply before you click post, look for this to add longer texts...

If you have a Mac with a rotating hard disk, it could be the hard disk is starting to fail. When this happens, a lot of times the disk will silently do a lot of Read retires until it can finally read the data. It can do hundreds for a single Read before giving up. Each retry has to wait 1 full revolution of the disk (rotational latency) which quickly adds up.


When a rotational disks gets really bad, it will sometimes fail, and your logs will report a disk error. EtreCheck, as asked for by BDAqua checks your logs for any disk read errors.
