LRC not recognise my raw files on new macbook pro

Did you move your catalog and images to the new computer?https://www.lightroomqueen.com/how-move-lightroom-to-new-computer/

If you moved everything properly and you still have this problem, then check that Lightroom Classic has full disk access:

Please explain the problem in more detail. There is no such "recognize" function in LrC. What steps are you referring to? What happens (or does not happen) that would cause you to claim files are not recognized?

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut out as that is just so much dead space to us non-Techs and it takes up vast amounts of scroll space making the reply less readable and less likely that others will bother with your post. Also large amounts of text in a post also render the Translate function inoperable.

Also, what camera?

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
