On a Mac, for ad-hoc OCR, I use the immensely useful CleanShot X https://cleanshot.com/ (which is well worth paying for).
Among many other things, it offes OCR of any region on the screen
for larger-scale OCR processing of pdfs and other files, I love how s3-ocr https://simonwillison.net/2022/Jun/30/s3-ocr/ makes working with AWS Textract OCR more accessible (though, somehow, Textract refuses to fully OCR larger pdfs I possess..)

On the latest MacOS, OCR happens automatically in any screenshot, or any image you open in Preview.
Try Command+Shift+4, grab part of the screen, click the pop-up, and just select text.
