Tweak it yourself Here’s some features you might have missed, and ways to remove some minor niggles, in OS X Yosemite and iOS 8. If you want to prevent your iPad from receiving the same texts as your iPhone, tap Settings > Messages > Message forwarding on the iPhone. Turn off the switch next to your iPad in the list of devices there to prevent it receiving texts. If you have an external mouse with a middle button, you can close tabs in Safari by middle-clicking the tab… … but that trick won’t work on a Magic Trackpad or Magic Mouse because they don’t have middle-click functions. You can configure gestures that will simulate a middle-click using the free MagicPrefs utility, which you’ll find available at magicprefs.com. The Markup toolbar in Preview has a squiggly icon that lets you capture your signature. Either sign with your finger or a stylus directly on your trackpad, or sign on white paper and hold it up to your Mac’s camera. You can use this signature to sign PDF documents. If you don’t like the Helvetica Neue font in Yosemite, you can revert to Lucida Grande using the Automator application at github.com/schreiberstein/ lucidagrandeyosemite. This works by adding a new font file, and doesn’t actually change any existing system files.
