Editor’s note: The following review is part of Macworld’s GemFest 2013. Every day (except Sunday) from mid-July until late September, the Macworld staff will use the Mac Gems blog to briefly cover a standout free or low-cost program. You can view a list of this year’s apps, updated daily, on our handy GemFest page, and you can visit the Mac Gems homepage for past Mac Gems reviews.
The inconvenient truth is that, while saving energy on your Mac by automatically dimming its screen or even sleeping the CPU is good and all, it can sometimes be a pain in the neck.
