![]() If you don’t like these changes, you’ll have to put up with the visual glitch until Apple gets around to fixing it.Ĥ. When you enter a Space on one display, the other display shows a blank screen instead of other apps. ![]() Both displays combine to create a single large desktop, and windows can span the gap between displays rather than showing on only one.You get only a single menu bar on the main display, rather than the active app on each display having its own separate menu bar.In fact, with “Displays have separate Spaces” turned off, OS X behaves much like it did before 10.9 Mavericks. Making this change has numerous side effects, so you need to figure out which behavior you prefer. You must log out and back in for this to take effect. We anticipate Apple fixing this in an update, but if it really bothers you, Jeff Carlson discovered a workaround: disable “Displays have separate Spaces” in System Preferences > Mission Control. Menu Bar Items Redraw When Switching Displays - Those who use Yosemite on a Mac with multiple displays may be seeing an ugly visual glitch that causes menu bar items to redraw when switching between displays. Jason Snell of Six Colors discovered some Terminal commands that reportedly fix the Save dialog, but one of his readers suggested an easier way: hold the Shift key down, hover over the left or right edge of the dialog until the cursor becomes opposing arrows, and then drag inward to shrink the Save dialog.ģ. Save Dialogs Expand Offscreen - Have you ever tried to save a document, only to find that you can’t see the Save button because it’s off the screen? A bug in Yosemite can apparently make Save dialogs grow in height by 22 pixels each time one is opened. You can re-enable AWDL and AirDrop without rebooting by entering this line in the Terminal.Ģ. If you see the error message “ifconfig: interface awdl0 does not exist,” you have older hardware that doesn’t support AWDL. (Unfortunately, it doesn’t persist between reboots, so you’ll have to apply the fix every time you reboot your Mac.) Copy the line below and, at the command line in Terminal, paste it, press Return, and enter your password. But when it works over AWDL, it appears to strain the hardware, hurting performance.įortunately, it’s easy to disable AWDL, but the fix also disables AirDrop and requires working at the command line. In the past, Bonjour was used only over standard Wi-Fi networks or Bluetooth. AWDL is a low-latency, high-throughput, peer-to-peer connection that runs over Wi-Fi but has its own dedicated network interface (much like general Wi-Fi or Ethernet). What he discovered is that in Yosemite, Macs are using Bonjour over Apple Wireless Direct Link (AWDL) to discover devices to connect to for AirDrop, AirPlay, and other services. We were puzzled by these problems, none of which we experienced personally, but developer Mario Ciabarra believes he has found an explanation for at least some of the problems. ![]() Miscellaneous Wi-Fi Issues - Since the launch of Yosemite, we’ve heard hundreds of complaints about various Wi-Fi connectivity issues: spotty connections, slow speeds, high latency, and more. And remember, since it’s one of our new Crash Courses, you can read it online for free!ġ. If you’re just getting started with Yosemite, be sure to check out Scholle McFarland’s “ Yosemite: A Take Control Crash Course” for information about what’s new and how to take advantage of Yosemite’s new features. Here then is a collection of five problems and solutions (or at least workarounds) that we’ve either experienced or had reported to us. OS X 10.10.1 Yosemite has been out for a bit now, though, and while it’s working fine for many people, there are still a variety of complaints making the rounds on the Internet (for what was fixed, see “ Apple Releases OS X 10.10.1, iOS 8.1.1, and Apple TV 7.0.2,” 17 November 2014). It’s common advice to wait for the X.Y.1 release of a new version of OS X before upgrading, since Apple often fixes bugs that crop up at launch quickly.
