Mac OS X icon preview or thumbnail problem
Since a year now I've been working with two new iMacs (Capitan, HighSierra) I noticed that had some problems loading the miniature previews of images files and thought that I just was doing something wrong, but now that I have just bought a new iMac (HighSierra) when I opened fresh new the first thing I tried was transferring my old images to the new one and continues without previewing the thumbnails, to be exact it's not happening with all images the same, there's some technical aspects related to it.
I tried these problematic image files with an old 2008 old Macbook (Leopard) and loads the preview images fast with no problem. It always worked good previewing loads of images and this shouldn't happen at all with better and newer Macs. This is a real problem when working with hundreds and hundreds of heavy images and affects seriously the normality of the workflow. I tried the basic solutions with no success (safe mode, options of visualization, erasing .plist, formatting, etc) Can it be solved?
iMac, macOS High Sierra (10.13.4)
