Not sure what happened. Maybe when upgrading to build 15077 or upgrading to OS X 10.9, but now the browsing operation is very slow.
MacBook Pro, OS X 10.9 -- PM 5.0 Build 15077
2 Ghz Intel Core i7, Memory 16GB 1333 Mhz DDR3
The application WAS very fast. Now it takes about 2 secs to select an image, from 4 to 6 secs to open an image in preview (50% to open , 50% to sharpen); in preview mode takes about 4 secs to advance to ned image.
I did the upgrade to OS X 10.9 and to build 15077 a coupe of weeks ago and since then the application has been very slow. I tried resetting the cache but nothing change. I don´t remember which I updated first OS X or PM 5.0 build 15077 .
The slide shows run very well, very fast.
What can I do to recover the speed?
