Adobe flash os x mavericks1/13/2024 ![]() In the technology world, sexy usually means more, better, faster. Energy summaryĬonserving energy is not sexy. Mavericks really does consume less energy than Mountain Lion when performing the same tasks. These tests may or may not be representative of how you use your Mac, but regardless, it’s clear that Apple’s efforts have not been in vain. The next time you’re about to run out of juice on your MacBook, think about how much you’d pay to put an extra hour or two back on the clock. Some of the lower-scoring Mountain Lion trials may have also had the bad luck to coincide with energy-intensive periodic jobs-jobs that are prevented from running on Mavericks due to AC power or battery-level restrictions as part of centralized task scheduling.īut even on Mountain Lion’s best day, the increase in battery life for Mavericks on the new MacBook Air is nothing to sneeze at, typically providing an extra two hours of work time in our tests. I suspect the aggressiveness of the auto-playing Flash ads that happen to be on specific websites on a particular day may partly explain the huge variability in Mountain Lion’s numbers. Can Mavericks do anything at all for this old clunker? You bet it can.Īll of this is to say that the MacBook Air’s impressive 30 percent increase in battery life shown above probably depends heavily on many factors outside your control. The Core 2 Duo CPU and discrete GPU in this Mac also lack the amazing low-power idle capabilities of the latest Haswell-based MacBook Airs. ![]() The first test system was my venerable pre-unibody 2007 MacBook Pro, so the numbers obviously don’t reflect the modern experience of using a Mac laptop. These tests were run on the GM build of Mavericks and OS X 10.8.5 with all updates (as of October 4, 2013) applied. I also installed Flash Player in both Mavericks and Mountain Lion, and I intentionally chose some websites that include Flash. Briefly running the test on Mavericks and inspecting the running applications in Activity Monitor revealed that some applications do indeed enter App Nap between the spurts of automated activity. To test this, I created a light Web browsing and text-editing automation script specifically designed to allow applications to remain idle for several seconds between each action. It stands to reason, then, that a clean installation of Mavericks running only bundled applications should exhibit better battery life than those same applications running on Mountain Lion. Though applications will have to be updated to take full advantage of the energy-saving enhancements in Mavericks, Apple has had some time to practice what it preaches and has updated the applications and background tasks that come bundled with the OS.
