How To Retrieve Forgotten Web Site & Browser Passwords in Mac OS X via Command Line
You can retrieve forgotten website and browser passwords by using a command line tool in Mac OS X. This is a handy feature that gives you access to the Keychain via Terminal.
How many times have you forgotten the password to a website? Don’t feel bad because it happens to the best of us. The good news is that if you use the Mac OS X Keychain feature to keep track of login information for websites through your browser (you know when the browser asks to save/store your login information?), you don’t need to worry, all you need is the websites URL and you’ll be able to retrieve a forgotten password as long as you’re logged into the same user account that you originally saved it with. This will work for all websites that have stored information through Chrome, Safari, Firefox, and it should work for any other browser as well. This is a great alternative to using the “password reset” or forgotten password features that are multi-step processes on many web sites and services since it doesn’t require any internet connectivity.
The iPad and iPhone don’t freeze or crash often, but when they do it can be an epic freeze-up, where the device can either get stuck in an app or, worse, it gets frozen on the dreaded iOS “spinning wheel of death”, the little wait cursor that never goes away. Left on it’s own in that state, that spinning wheel can quite literally spin forever until the battery drains and the device dies out, but that’s obviously not a solution to resolve the rare major iOS crashes. We’ll cover three tricks to fix major iOS crashes, the first will attempt to just exit out of the crashing application, the next will forcibly restart the device, and finally for the worst scenarios, we’ll restore iOS as new, though that really should be a last resort that is rarely applicable to most situations.
If you’re a heavy command line user, you’re probably well aware that the arrow keys can be used to flip through previously executed commands and the tab key can complete them. But both of these functions can be significantly improved upon for searching through past command history by adding a few modifications to your .inputrc file.
Though it’s somewhat rare to encounter ownership and permissions errors in Mac OS X, it can happen, particularly when an account has been moved, or a files owner has been modified by a third party application. Oftentimes you can just run through the process to 
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.
