Handy Keyboard Shortcuts To Shut Down Mac Or Make Mac Sleep [OS X Tips]

By

Mac OS X Keyboard

Back in the day, I used to care for a couple of labs full of Macs. Invariably, I’d find myself in the lab at the end of the day, shutting them all down for the night. I’d run up and down the rows of eMacs or whatever they were at the time, and hit the power button, then click on the Shut Down button. Or, if I was feeling frisky, I’d just hold down the power button until they shut off.

This took some time, needless to say. I wish I’d known of these useful keyboard commands to shut down or sleep the Macs, saving myself several minutes each day.

Solarpad. Finally, A Proper Solar Charger For Hikers And Bikers

By

At an RRP of $200, the Solarpad isn’t the cheapest solar charger for your iPhone, but it does aim to be the best. Every detail has been tweaked to squeeze the last drop of juice from the Sun’s photons, from the battery itself (the same kind as Tesla uses in its cars apparently), through the efficient charge controller (form Maxim) to the cables themselves (fatter, to let the current flow more easily, says the blurb).

What’s more, you can pitch in early on Kickstarter and get a full setup for just $158 (right now anyway – the campaign only just launched).

The thing is, by the time I’d bought all the parts (plus a roll of gaffer tape), I’d be in the hole for way more than the $25 Quirky want for its version.

OS X Mavericks has some crazy new power-saving technologies, as demoed yesterday at the WWDC Keynote. Most of these are system-based: the OS stops wasting CPU cycles running animations that are hidden behind another window, for example. But some, like this neat addition to the battery menu, are about advising the user what’s sucking the juice.
