      and Not sure how it got so ugly and hard to read, but, here I take a librity  and rework what you posted concerning your system information

       

       

      Lightroom Classic version: 8.4.1 [ 201909111355-eb9b68f0 ]
License: Creative Cloud
Language setting: pl-PL
Operating system: Mac OS 10
Version: 10.13.6 [17G8030]
Application architecture: x64
Logical processor count: 4
Processor speed: 2,7 GHz
Built-in memory: 12 288,0 MB
Real memory available to Lightroom: 12 288,0 MB
Real memory used by Lightroom: 2 254,8 MB (18,3%)
Virtual memory used by Lightroom: 7 318,2 MB
Memory cache size: 737,5MB
Internal Camera Raw version: 11.4.1 [ 291 ]
Maximum thread count used by Camera Raw: 3
Camera Raw SIMD optimization: SSE2,AVX
Camera Raw virtual memory: 1774MB / 6143MB (28%)
Camera Raw real memory: 1782MB / 12288MB (14%)
Displays: 1) 2560x1440

Graphics Processor Info:
OpenGL: AMD Radeon HD 6770M OpenGL Engine

Check OpenGL support: Passed
Vendor: ATI Technologies Inc.
Version: 4.1 ATI-1.68.23
Renderer: AMD Radeon HD 6770M
OpenGL Engine LanguageVersion: 4.10
Total Video Memory: 512 MB

Application folder: /Applications/Adobe
Lightroom Classic Library Path: /Volumes/My Passport/foto_PF4/MOZK/mozk/mozk-2.lrcat Settings Folder: /Users/ziggy/Library/Application Support/Adobe/Lightroom

Installed Plugins:
1) AdobeStock
2) Aperture/iPhoto Importer Plug-in
3) Facebook
4) Flickr
5) Nikon Tether Plugin

       

       

      Now what stands out as wrong is the GPU info

       

       

      Graphics Processor Info:
OpenGL: AMD Radeon HD 6770M OpenGL

Engine Check OpenGL support: Passed
Vendor: ATI Technologies Inc.
Version: 4.1 ATI-1.68.23
Renderer: AMD Radeon HD 6770M
OpenGL Engine LanguageVersion: 4.10
Total Video Memory: 512 MB

       

       

      For MAC  OS, in Lightroom Classic, METAL, not OpenGL should be in use.

      See Solution 3 in: https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-gpu.html

       

      Also, as your Video Memory appears to be  just 512 MB, attempting to use the GPU for acceleration will probably not work

      See “ Minimum system requirements to use GPU for image processing” in: https://helpx.adobe.com/lightroom-classic/kb/lightroom-gpu-faq.html

       

      And as your display is not 4K, using the GPU for acceleration will probably not accomplish anything. So, reccomend that be turned off

      Please post your system information as Lightroom Classic reports it, from first line down to just past plug-in info.

      Paste into your reply, that is paste, not add as a attachment.

      And if is not it, consider a possible  corrupt colour profile

        Go to Preferences > Performance tab. Deselect Use GPU for display. Close Lightroom and restart.
