MacOS 15 Finder is Broken Shit

When I upgraded my 14 year old Mac Mini to the latest Mac Mini Pro this year, I was expecting everything to get faster and mostly better.

But one thing has become slower than molasses.  And that is Finder with large folders.  And I'm not talking super large, like >32k files.  Just a few thousand files can slow Finder to a crawl when loading folders.

Apple says you shouldn't have large folders?  WTF???  I remember when folder sizes became virtually unlimited in Unix, and that was like 50 years ago.

In addition to that, the new Finder display modes are virtually useless too.  My old system did gallery displays with thousands of files virtually instantly, and I could quickly zero in on an image I wanted.  Now it's useless, and I'm better off using some other application like PictureView to scan files for one I want.

I waited about 10 minutes for Finder to load a folder of 3000 files.  Finally I gave up and rebooted the system.  It wouldn't reboot the first time because Finder was stuck and needed to be terminated.

Fortunately this doesn't seem to be true of the underlying file system.  I can work on folders with large numbers of files just as fast in Terminal as ever before.  That's getting much closer to the system functions, which may be OK.  It's just Finder that's been broken.
