Sinse I update my SO to Mac OSX lastest version MAC OSX Yosemite 10.10.3 I have problems with camera Raw in two diferent coputers using Photoshop CS5.
When you open diferent archives to proces in Camera Raw, always miss some of them. You can open one of them, or all archives individually. But if you open 4 archives, Camera Raw only get 3.
Or if you open 6, camera raw only get 5, or 4. Some times, after canceling the operations, opens automaticly the missed archive.
The problem persists in the other computer exactly.
What can I do to fix it?
Please try and update the Photoshop CS5 to the latest update.
If the above solution doesn't work, then uninstall the Photoshop CS5
Restart the Mac
Install it again using the Link: Download CS5 products
And then try it.
Let us know if it helps.
