Macs have pretty amazing battery life to begin with, but following a few simple tips will help you to get the absolute best battery performance out of a MacBook, MacBook Air, or MacBook Pro.
The primary goal here is to reduce overall power consumption on the Mac laptop and we’ll cover a few different techniques to do this. For casual Mac users simply reducing screen brightness is typically more than adequate to get great battery life, so the tips below are intended for true road warriors who demand the absolute best battery life possible out of their portable Macs.
Looking for some nice mellow wallpapers to add to your Mac, iPhone, or iPad? The DizzyUp collection features three beautifully subtle wallpapers in a wide variety of common screen resolutions and has also been updated to support the 3rd gen iPad retina 2048×2048 display. The wood paneling is my personal favorite of the group, but if you’re into minimalist wallpapers you won’t want to miss the other two dark & light wallpapers either, which feature unobtrusive gradients over a some gentle patterns.
Forwarding text messages from one sender to another is made very simple on the iPhone. The process is the same whether it’s a text, SMS, MMS, or even an iMessage:
From the Messages app, open the text message you want to forward
Tap the “Edit” button in the upper right corner
Tap the message you want to forward so that it shows a red checkbox next to it
Tap on the “Forward” button in the lower right corner
Enter the recipient in the new message screen and send as usual
The forwarded message sends to the recipient as any other message would, and an SMS or MMS can be forwarded as a mass text message as well. Group texting is useful for reducing text message fees with some providers and it’s also a great way to annoy your entire iPhone address book.
And yes, text messages can be forwarded from an iPhone to iPad, iPod touch, or Mac running Messages, and vice versa, though sending to a device other than an iPhone obviously won’t register as an SMS.

Apple has released a standalone removal tool that targets Flashback malware infections. The separate utility is recommended for Mac users who do not have Java installed on their OS X Lion machine, but it’s functionality is identical to that performed by the most recent Java update to remove Flashback.
If your Mac does not have Java or you did not install the most recent Java for OS X updates, running this tool is a good idea. Here is what to do:
Mount the DMG file and launch FlashbackMalwareRemover.pkg
Click Continue, click “Install” and enter the administrative password
Everything beyond that is automated, if the Mac is infected it will be automatically repaired.
Users should always keep system software up to date as part of a general maintenance routine. Despite the recent media overhyping of Flashback, Mac OS X remains a very secure platform. If you are concerned about potential attacks, our recent guide on securing Mac OS X from potential trojans and malware may be helpful to you.
Want your Mac setup featured? Send pictures of Apple & Mac setups to osxdailycom@gmail.com and include some brief hardware details and what you use it for.
Want to share a single keyboard and mouse between multiple Macs? How about using a keyboard and mouse attached to your Mac to control an additional PC running Windows or Linux, and even being able to share copy and paste data between the different operating systems? You can do that with the help of a great free tool called Synergy, and setting it up is easier than you might think. Read more »
Apple was busy dreaming about the future of communications 29 years ago, long before the days of the iPhone, touch screens, cell phones, and even cordless phones.
Apple has released a new Java security update that automatically removes the most frequently occurring variations of the Flashback trojan malware. The software update is recommended for all Mac users to install, even if they have previously checked their systems for infection.
To get the update and remove any malware that is potentially on a Mac, simply download the “Java for OS X 2012-003” update from Software Update found within the Apple menu. There is no manual checking or removal required, simply installing the update from Apple resolves any potential infection for you.
The new Java update also disables automatic execution of Java applets, providing further security against potential threats down the road. Release notes are as follows:
This Java security update removes the most common variants of the Flashback malware.
This update also configures the Java web plug-in to disable the automatic execution of Java applets. Users may re-enable automatic execution of Java applets using the Java Preferences application. If the Java web plug-in detects that no applets have been run for an extended period of time it will again disable Java applets.
This update is recommended for all Mac users with Java installed.
For details about this update see: http://support.apple.com/kb/HT5242
Designers and developers will appreciate the newly released retina iPad GUI elements template available now as a free PSD download from Teehan+Lax. Based on iOS 5.1 and the new iPad’s retina UI elements, these PSD files are an excellent resource for quickly mocking up iPad apps, workflows, and general iOS concepts.
You’ll need Adobe Photoshop to properly use the PSD file and it’s intensive layering, but the excellent Photoshop CS6 beta is still free to download and use until the final release comes out later in the year.
We’ve posted a lot of these UI element and iOS and OS X design templates here before because they’re so useful for both developers and designers. If you missed some of those past posts, varoius PSD templates are available for OS X Lion elements, non-retina iOS UI, iPhone & iOS 5 UI, and even retina iOS icon templates.
The “Other” capacity in iTunes is supposed to estimate the size of system software, contacts, Messages data, and things that are not listed elsewhere in the labeled capacities list of storage on an iOS device. Sometimes other data will become mislabeled or misappropriated to the “Other” category, and suddenly it’s reported as being much larger than it actually is on an iPhone, iPad, or iPod. Read more »
A users .bash_history file keeps a running tab of command line history, logging every command that has been entered into the bash prompt. These command history files make it very easy to find and recall past commands that may have been forgotten, and they’re also extremely useful for system administration. We will cover how to change the stored length of these files, how to disable it, and also how to quickly check a users bash history.
Changing Bash History Length
To increase the history length of a users command history, add the following line to .bash_profile:
HISTFILESIZE=2500
The example above will increase the history size to 2500 commands, that can be changed to any other number as deemed appropriate.
Disable Bash History
Setting the HISTFILESIZE number to 0 within .bash_profile will disable bash command history completely:
HISTFILESIZE=0
Having the history file disabled does not effect command recall, but it does prevent a super user from easily seeing the commands entered into another users shell.
Checking Bash History
There’s a few quick ways to see command history, to see your own type:
history
You can also export that command history to a file with the -w flag:
history -w pastbash.txt
To see another users command history, use cat with their .bash_history file instead:
cat /Users/USERNAME/.bash_history
Remember that if USERNAME has set their history file size to zero, nothing will be shown.
Practical Applications for Mac Users
Two of the most common applications for a Mac user is to keep track of defaults entries that have been entered into the Terminal and to quickly find past commands. Query command history and you won’t have to guess what that obscure command was that you entered four months ago that started with a ‘s’.
Assuming you have file extensions shown in the OS X Finder, attempting to change a file extension causes a warning dialog with a confirmation box to appear. The warning text says “Are you sure you want to change the extension from (this) to (that)?” then giving you two choices; keep the current file extension, or use the new extension.
That dialog box can be annoying if you know what you’re doing and you have a compelling reason to change extensions, which is often the case for advanced Mac users, so let’s turn it off using one of two methods in OS X; with the Finder Prefs panel, or the command line and defaults write.
If you saw our Air Display review you’ll know it’s a pretty awesome app that lets you turn an iPad into an external display for a Mac or PC ($10 on the App Store). If you bought it and haven’t figured out what to do with it yet, here are eight of our favorite ways to use Air Display as an auxiliary screen.
Dedicated Music Player – Listening to music while you work is a must for many of us. If your favorite music client is in OS X than why not offload the app to the external iPad display? iTunes, Spotify, Pandora, Rdio, whatever you use, you’ll save valuable screen real estate and have an easier time switching through songs
App Launcher, Tool Panel, & Dock Holder – Move the OS X Dock and apps tool panels over to the iPad screen and you can save some screen real estate, this is especially helpful for smaller laptop screens
Dedicated RSS Reader – News junkies can never miss a beat by throwing their favorite RSS reader onto the Air Display screen, this lets you keep a constant eye on the latest posts from your favorite publications without cluttering up your main screen or having to switch windows on the Mac
Twitter Monitoring – Twitter has a myriad of uses beyond tweeting that Instagrammed picture of your breakfast. It’s one of the best ways to monitor brands, sports, news, sentiment, pop culture, your favorite people, and a million other things. Follow some worthwhile Twitterers (starting with @OSXDaily of course) and throw your Twitter client on the Air Display to stay in the loop.
Dedicated Chat Screen – Whether it’s Messages, iChat, FaceBook Messenger, or IRC, if you spend a lot of time talking online, pushing that window to another screen is a great way to free up your main display real estate while still keeping active in chat
System & Resource Monitoring – GUI utilities like Activity Monitor and command line tools like htop, iotop, and top are excellent ways to keep an eye on system resources. This is most useful for advanced users, but it also just looks cool to have a screen full of crazy terminal stuff flying around
Watching Logs – Open Console app and watch local system logs, or use the Terminal with tail -f to follow other logs and files as they update live. This is probably most useful to advanced users, but you can also pretend to be very busy while daydreaming at work or school by having a screen full of active system logs
All of the Above – Mix and match a few of the options up top to get the best of everything. Throw an htop window at the top and a slim iTunes window at the bottom, or whatever other combination of auxiliary screens you can come up with
You’ll notice anything graphics intensive isn’t mentioned in this list because Air Display has to transmit all data through wi-fi. That connection doesn’t provide for precision tracking or smooth playback of video, so we chose things that work perfectly given the apps limitations. If you have any other ideas or uses for Air Display and the iPad, let us know in the comments.
Spilling coffee on something is generally considered a bad thing, but not if you have a brown leather iPad Smart Cover. TwoLivesLeft accidentally got some coffee on their iPad case, and then had the hilarious epiphany “I had a wonderful, horrible idea: I’d stain the cover with coffee“. The result? A surprisingly attractive appearance that looks like beautifully refined leather, akin to something dug out of an old dusty library.
Speaking from my own experience of spilling coffee on porous things, the Smart Cover will undoubtedly smell like liquid crack for a very long time. Whether that’s a bad thing is your call, but I won’t be trying this myself. if you’re brave enough to give it a go we’d love to hear about it.
Fascinating discovery by CultOfMac, best of luck to anyone who tries this.
When it’s not in use, do you shut down your Mac, put it to sleep, or just keep it turned on? Is one choice better than the others? Why and why not? These are great questions, so let us review the choices and why you may want to choose one over the other.
Sleeping a Mac
This is my preferred choice because it provides for the easiest and fastest way to resume work while still maintaining hardware. It’s practically instantaneous to sleep a Mac and when you wake it up all of your open apps, documents, window arrangements, and web pages, are exactly where you left off with practically no delay. For the average Mac user who wants to quickly get back to what they were doing, sleeping is perfect.
Pros: Quickly resume exactly where you left off; sleep and wake can be scheduled or even done remotely
Cons: Minor power consumption; system temp, swap, and cache files don’t get cleared out during reboot process; system updates requiring reboots don’t install automatically without a manual reboot; performance is best for Macs with 4GB RAM or more
If you use the Mac every day, simply putting it to sleep when it’s not in use or overnight is probably the best choice. Just be sure to remember to reboot every once in a while to allow system software updates to install as part of a general maintenance routine, though waiting for an OS X Update or Security Update is generally a sufficient time between reboots. You can also gather some gigantic uptimes with this approach which is pretty much a useless statistic other than the nerdy bragging rights, (I’m currently at 35 days, weeeee!) but hey it’s fun to check anyway.
Shutting the Mac Down
I basically never shut down a Mac unless it’s going into a longer term state of inactivity or storage. Shutting down a Mac is slower since all open applications and documents have to quit, and then when you turn the machine back on everything has to re-open again to get back to where you were prior to shutdown. OS X Lion made resuming past application states much simpler with the automatic window restore feature (which some dislike and choose to disable), but I still find it too slow to be usable for my instant-on demands.
Pros: Saves power, doesn’t strain hardware; system temp, memory, swap, and cache files get cleared out during boot; allows for major system updates to install
Cons: Takes a while to boot up and resume previous activity, no geeky uptime bragging rights
For the power conscious or for those trying to squeeze the absolute longest lifespan out of hardware and hard disks, shutting down when not in use is the best choice. This is also what you’ll want to do if you’re going to put a Mac in longterm storage, won’t be using it for a longer than a few days, or if you’re going to be traveling with a Mac that isn’t in use during the travel period.
Keeping a Mac Always Turned On
Leaving a Mac constantly turned on is another viable option, though I think it’s best reserved for Macs that function as servers. This approach also carries the most polar advantages and disadvantages. On the plus side, you don’t have to bother resuming anything since it’s already on, you can schedule all maintenance and backup tasks to occur in the wee hours of system inactivity, and it allows for something like a constantly available SSH server or media center to be running on the machine. The downsides are basically the constant power consumption and the constantly active hardware, which can limit overall lifespans of the computer components.
Pros: No waiting for use; instantly resume all apps and tasks exactly where you left off; allows for servers to run with constant accessibility; backup and system maintenance tasks can be scheduled for off hours
Cons: Constant power consumption; more wear and tear on hard drives, fans, and physical hardware due to possible heat
If you’re running a server or media center, leaving a Mac turned on constantly is a no brainer. For the casual Mac user, it’s probably best to put a Mac to sleep when it’s not in use though, it gives hard drives and fans a rest, and will generally lead to a longer lifespan of the computer.

The iPad picture frame app is a nice way to put a stale iPad to use as it sits on a desk. That resulting live picture frame is made even better when a custom album is created for the purpose, but if you use photos of people you’ll find that Picture Frame automatically zooms in their faces. Great if the album is intended to showcase people, not so great if you’re trying to show the wider scene.
If you don’t want the picture frame to focus on faces, you can toggle the feature off quickly.
