Treat your Mac to World Backup Day

This Sunday, March 31, is World Backup Day, an independent initiative geared to raise awareness for data security and the importance of backing up computers and other devices that may contain important information. In light of this, you might want to consider taking the time to ensure that all of your systems are set up with a proper backup routine.

Backing up a system used to take a number of steps, and while there are many options and approaches for doing so, these days most devices include some sort of regular backup option that, if used, should be enough to … Read more

How to manage transparencies in Preview

Transparency in images files can be quite convenient, especially if you need to place the same image over different backgrounds and want it to properly blend in. While having a white or other solid color background may help you view the image on the screen, with this setup if you embed it in a document with a different-color background then the white will stand out as an obtrusive rectangle.

To help reduce this, you can both manually remove backgrounds from images using Apple's Preview application or use a transparent canvas to compile images that already contain transparency.

Tips for using the Dashboard in OS X

Apple's Dashboard feature in OS X is a convenient way to access widgets for looking up information on your system. The default behavior for Dashboard is to activate when a hot key is pressed (the default being the F4 key), where the system will present the dashboard as an overlay to your current desktop. This is the setup most users are accustomed to. However, if you would like, you can make some modifications to this and have widgets appear in their own space -- or even have them be embedded on your desktop.

The first option is to have … Read more

How to set up password policies in OS X

Generally each account on an OS X system is protected with a password; however, the security of a system can be compromised by the use of an insecure password. For example, common passwords like "12345," "password," or "letmein," or short passwords may be easily guessed. Sometimes account holders on a multiuser system may even use a blank password, which can easily let anyone into their accounts. By default OS X will warn users of such practices and recommend strong passwords be used, but ultimately does not prevent users from setting whatever password they want.… Read more

How to address ColorSync profile errors in OS X

Apple's ColorSync technology in OS X uses calibrated profiles of correction curves and other scaling factor information to match the color of various image input and output devices such as monitors, printers, and scanners, so images viewed on them will appear as close as possible.

Most devices will use a factory-provided profile or a generic one to give a close color match, but these often have notable color discrepancies that in some cases you can manage by creating your own profiles. For example, for matching colors across different displays, you can use the Calibrate button in the Color section … Read more

How to unlink a file type in OS X

For every application installed on your Mac, OS X will scan its document-handling capabilities and store them in its Launch Services database, which it then uses to pair up document types with the applications that are built to handle them. Therefore, if you install a new image-handling tool on your system, when you right-click image files or get information on them you should see this program be available in the "Open With" section as an optional handling program.

This service is convenient for ensuring that documents can be opened directly from the Finder; however, it assumes you always … Read more

Tackle IMAP e-mail not being stored on server

Apple's Mail e-mail client supports a number of different messaging protocols including POP and IMAP, but if you convert an existing account from POP to IMAP then you may run into a problem in which e-mails are longer saved on the server.

MacFixIt reader Bruce recently wrote in with such a situation:

I have recently tried to convert my wife's AOL email from POP to IMAP. I did this by adding a new account in Mail. When she sends messages with the new account, the sent messages do not show up on the server, even though I have … Read more
