    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

    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.

    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.
