I'm using Lightroom v5.6. I recently changed my laptop from Windows to Mac.
Right now, whenever I want to import my photos, my photos are not sharp and clear in the Thumbnails unless i get into Single photo preview.
any idea why is this happen and how can i resolve this..
Thanks appreciate for your help.
Since the thumbnails are coming from your unprocessed files, and are initially being processed for speed instead of accuracy, this is not unexpected in the import dialog.
If you wait for the files to be background processed, the quality of the thumbnails in the import dialog may improve slightly.
