*Cross post from Nikon Cafe! I recently installed this app from here on both my Mac Mini and MacBook Air: Turbo Boost Switcher for OSX / macOS The Mac OS automatically controls how your CPU throttles it's speed. This app lets the user remove the training wheels! As long as you have a Turbo Boost capable CPU on your Mac, you can use this app. I have both a dual core i7 and a quad core i7 and the difference seems quite noticeable with more cores. In terms of performance I've timed anywhere from 3-5 seconds shaved off from doing raw-to-jpeg conversions using Camera Raw into Photoshop! Doing the math at minimum: Saving 3 seconds from a batch edit of 100 photos equals 5 minutes of saved time! Try it out! BTW - I also recommend downloading this fan control software to monitor your temps and fan speed: smcFanControl for Mac | MacUpdate * One more note: If you're on a Mac laptop, I'd recommend turning it off when not photo editing to maximize battery life. Get the best of both worlds!
