Many pictures are blurry/pixelated on new computer

[heatherr75292445]

I am solely using Lightroom CC for my pictures.  I just got a new Mac, and many of my previous pictures in Lightroom CC are now blurry or pixelated.  But not all of them.  Some (in the exact same folder) are perfectly fine.  I am a total dunce when it comes to things like this, and have not been able to figure out the issue.  Any suggestions?  Many MANY thanks in advance!!

Edited to add:  all of my pictures came onto my new computer when I synced by old Mac to my new Mac.  So I didn't have to do anything.  They were <poof> there on the new computer.

Hi Heather,

If you are using the Cloud Based Lightroom (version 3.2) then that stores a certain percentage of full resolution photos in the local cache (the percentage can be set in preferences). These full res will be a mixture of recently imported and edited photos.

On the new computer the full res have to download from the Cloud, so may just be a preview. If you try to edit one of the problem files, does it get sharper?

Hi Selodon - thanks so much for the quick reply!  The picture does not get any better when I go to edit it.  I wish I knew more about what the heck I was doing.  I need to take a class in Lightroom CC obviously!  Below is a SS of my local storage window.  I see where you are talking about the %.  Are you suggesting that I increase that?

Many thanks!

Heather
