How to Make an iPhone Screenshot

Want to take a screenshot of something on your iPhone or iPod touch? Press the Home button and Power button briefly at the same time, and an image of your screen will be saved to the Photos app (and will sync with iPhoto when you next connect). Don't hold the buttons too long or your device will either power down or reboot.

OS X 10.9.4 Includes Wi-Fi, Wake from Sleep Fixes

Send Article to a Friend

Apple has released OS X 10.9.4 Mavericks. The 283 MB update is available via Software Update, and should be available soon from Apple’s Support Downloads Web site.

Highlights of the update include a fix for a bug that prevented some Macs from automatically connecting to Wi-Fi networks (for other suggestions, see Alicia Katz Pollock’s “How to Solve Wi-Fi Connectivity Problems,” 7 February 2014), improved reliability of wake from sleep, and the inclusion of Safari 7.0.5, which features a number of security fixes.

Bundled into 10.9.4 are the usual slew of security improvements, including an update to the certificate trust policy, a fix for sandboxed apps being able to circumvent restrictions, and elimination of an issue that could allow local users to see Apple ID credentials in iBooks logs. Other fixes eliminate problems related to the Intel graphics drivers, issues that could cause unexpected restarts, bugs that allowed arbitrary code execution, and a number of vulnerabilities in Unix system utilities.

Still broken after months...

1. First Finder window after reboot always shows some 'default' settings (size, column widths) but never what it was last set to.

2. After switching from internal MacBook display to closed-lid mode the Finder windows are always misaligned. Same goes for Mail windows. Sometimes Finder windows even revert to 'default' settings instead of what the user last set them to.

3. When waking in clamshell mode, the external screen sometimes remains dark despite the MacBook having woken up. Sometimes repeatedly hitting keys or moving the mosue doesn't even help. In these cases, hitting ctrl-shift-eject (= sleep screen) and then hitting other keys (to wake screen again) sometimes does.

4. Alignment of icons on desktop changes for no apparent reason every once in a while.

5. Weather widget in Dashboard gets garbled display after a few days of use.

And yes, it's all been reported to Apple.

My friends wonder why I haven't updated.I wonder what happened to " It Just Works."there was a time when that slogan was true . but since iPod iPhone and iPad I suspect all the best coders work on the toys and Macs get what's left

They seem to have made some significant changes to the GPU subsystem.
On my 2012 rMBP firing up iPhoto or some java apps (Freemind) would cause a switch to the discrete GPU. Now it doesn't.
I noticed this because now my computer crashes within a few minutes of use with my external display connected. To troubleshoot, I decided to try forcing the dGPU without the external display attached. Strange that the graphics switching option in Energy Saver doesn't seem to be having any effect either -- its still using the HD4000.

UPDATE: It seems that not switching to the dGPU was a glitch. After rebooting, my machine switches to the dGPU when I launch iPhoto, or turn off automatic graphics switching. When the dGPU is in use, my system crashes, randomly, but steadily.
