Numbers is intended to be an intuitive alternative to Microsoft Excel and other popular spreadsheets, but as a calculation program it is perhaps not much to expect it to perform calculations properly. However, there are instances where the program may incorrectly calculate values you enter. One of these is if you attempt an odd-root (e.g., the cube root) of a negative number, where there is a mathematical answer, but which causes Numbers to give an error when attempted. Continue reading
Are you ready for the Yosemite 10.10.3 public beta?
Apple has released the second developer build of OS X 10.10.3 as a public beta available for download today. This update is much anticipated, because in addition to the standard bug fixes and security patches, Apple is including an all new app called Photos. This app, which is slated to replace both iPhoto and Apple’s pro photo manager Aperture, will bring a streamlined interface for managing photos and allow you to do so with local libraries or those stored on iCloud, from your iOS and Mac OS devices. The program in essence unifies the photo management experience across Apple’s platforms. Continue reading
How to use the OS X Dock as a Command-Tab replacement
When switching between open Apps in OS X, you might generally use Command-Tab; however, you can do similar switching, and far more, directly in the Dock.

You may also see the battery life remaining on your system drop to an hour or two at most when you expected to have quite a few more. In addition to a hot system, you may also notice slowdowns with other tasks you attempt to perform, though this will depend on the task and might not always be the case. Continue reading
How to handle multiple disks simultaneously with Disk Utility
Regardless of the number of storage devices you have attached or built into your Mac, you will likely use Disk Utility for formatting them when necessary, to partition and resize them for various purposes, and otherwise managing them. However, one limitation you might find when using Disk Utility is that it will only act on one drive or volume at a time. Continue reading
How to check what kind of Mac you have
When Mac systems are discussed online, you will often see them mentioned by their common name, such as “Late 2012,” “Mid 2013,” or “Early 2013,” etc. These names suggest a model number, and sometimes are specific enough to identify your model in question; however, this is not the true model identifier of your Mac.
Along with the common model number, each Mac revision has a Model Identifier that is specific to the motherboard and Continue reading
