Delete Contacts from iPhone the Fast Way, All or Individually
Apr 23, 2013 - 15 Comments
Need to delete a contact from the iPhone? Maybe you want to delete all contacts from the iPhone, iCloud, Mac OS X, iPad, and everywhere else they appear, so that you can start anew with a completely blank address book? You can do both easily and quickly, and while deleting a single contact is quick and easy from iOS in the Contacts app, as of now the only way to delete every single contact in an expedient manner requires the usage of a Mac.

The newest Macs ship with a Recovery partition rather than a separate external reinstall disk, and if you’ve ever rebooted a newer Mac, iMac, MacBook Air, or MacBook Pro with an SSD from the Recovery partition to reformat the drive, you may have noticed that by default the “Security Options” button is greyed out in the Disk Utility options, seemingly preventing a 
Many older Macs lost out on the ability to run OS X Mountain Lion (10.8.3!), but some hard working fellows have created a free third party tool called MLPostFactor that allows for the newest version of OS X to be installed on older, officially unsupported Macs. The process used to be quite 
Whether you just got a new phone number, changed a number from an old one, or you happened upon someone else’s iPhone and want to know the number of who it belongs to, you can easily retrieve an iPhone’s associated mobile number. The obvious solution might be to call another phone, but if the device has no service or the service has been disconnected, don’t despair. There are two super simple ways to find the number on the device itself – even if the phone no longer has any service and no sim card – but you can also get it from iTunes and sometimes even on the sim card itself.
You can change the default alert times of calendar events on iPhone and iPad. 
Anyone who takes a lot of screenshots in Mac OS X knows the challenges associated with them; how quickly their desktop will fill up with various PNG files, sorting those into folders or just tossing them elsewhere, converting the screenshots to a different image format, copying them to the clipboard for pasting into another app, cropping down to size, or whatever else is required before the screen captures are in their final usable format.
Two new updates are available for Mac users that aim to increase security and control over how the Java web plugin runs in the Safari web browser. Named as Java for OS X 2013-003 and Safari 6.0.4 (or Safari 5.1.9 for older versions of OS X), the updates are available right now through Software Update via the Apple menu. The updates combine to roughly 110MB and requires Safari be quit before installing, though a reboot is not necessary, and should be considered must-have upgrades to existing software for those who use Safari and/or Java on the Mac.
If you have ever wished you could schedule the opening of a specific file, or set an application to launch on a specific date, either on a one off basis or on a recurring scheduled event, you can actually do both right in Mac OS X with the help of none other than the default Calendar app. Opening files and apps on a Mac at scheduled times is an astonishingly useful feature that is largely unknown, but it’s extremely easy to use. 
Anything to boost productivity and reduce time spent emailing is a big win in my book. Accordingly, the “Sent from my iPhone” signature attached to an email has become associated in everyones minds with brevity, since naturally nobody expects a lengthy email reply sent while on the go from a smartphone, right? As a result, short replies from smartphones and iPhones are not considered rude or overly brief, and you can use that expectation of a brief and concise message to your advantage when sending emails from the Mail app of OS X. This is a great way to improve your email productivity when writing and replying from the desktop, and while some people call it a brand vanity signature, I like to call it the “brevity signature”.
Practically all apps that store documents in iCloud let you delete them from the app itself, which simultaneously removes them from iCloud and thus all other synced iOS & OS X devices. But if you’re looking to manage and remove specific iCloud documents and data, there is a better way to do it through a centralized control panel within iOS that will let you view all documents stored in iCloud, much like the 
A little-known screen flashing feature exists in Mac OS X that provides an alternative way of being notified of system alerts, meaning that anytime you’d typically hear the general system sound effect feedback, see a bouncing Dock icon, or have a new icon badge appear, the screen will briefly flash instead. The screen flash alert is silent but offers unmistakable feedback that an alert has occurred, and can be used in conjunction with the standard alert sounds too.
