Aperture V3.6 has always loaded pictures vary fast, even when loading over 100 of RAW files (25 MB each). Now that I bought a new 27" iMac (late 2015 with 32 GB Ram) it takes for ever to load pictures. I loaded a small jpeg file, about 150K, and it took about 20-30 sec. to load. Does anyone have an idea why this is suddenly happening?
