Sometimes you need to enter a password into the terminal, usually for sudo or su commands, which lets users execute a command with super user privileges. This is fairly typical for allowing access to read or modify something that would otherwise not be possible with a standard user account. You’ll commonly see sudo prefixing another command, looking something like “sudo nano /etc/hosts“. Though most of the command line and sudo is generally only appropriate for advanced users, occasionally more casual computer users may need to turn to the Terminal, perhaps to enable a feature, modify a system file, or even for troubleshooting purposes. For novice users who wind up at the command line, a very common question occurs with entering passwords into the Terminal, almost always related to sudo and the apparent inability to type a password into the command line of Mac OS X (or Linux for that matter).

TextEdit is a surprisingly handy Mac app that is mostly underutilized and under appreciated, and while it’s certainly not going to compete with the abilities of pro text editors like BBEdit and TextWrangler, it can function as a simple code editor in a pinch. One of the quintessential features of any good text editor is the ability to jump to a specific line number, and TextEdit can do that.

This allows for scripting, remote checking and changing idle sleep behavior through SSH, and you can also use it to set the idle time requirements beyond what is allowed through the standard System Preference approach.

If you have ever switched from an iPhone to an Android or Windows phone, either temporarily, out of necessity, or for testing purposes, you may have noticed that a new phone will sometimes not receive inbound messages that have been sent from other iPhone users. Well, you probably didn’t notice it because you didn’t get any of the messages, but someone probably told you that they sent you a text and you never received it. These disappeared messages are almost always due to a quirk of iMessage, which seems to strongly couple itself to a phone number that belongs to an iPhone, and if not disabled or deregistered, that iMessage attachment can end up hoarding the messages in some sort of ethereal messaging purgatory, which then prevents them from being delivered to the new non-Apple phone. Fear not though, because you can get a phone number out of iMessage Purgatory by using one of two different methods outlined below.

Mac users who have multiple user accounts on a single machine may sometimes wish to hide a specific user account from appearing on the login screens of OS X. This is fairly common for systems administrators who want to hide an admin account that can be used for direct or remote troubleshooting, but it can also be applicable to other users for a variety of reasons. By hiding an account this way, the account login still exists if it’s known and it can still be accessed from remote login and screen shares, but does not appear at the boot screens as a login option.

Adware is generally something most Mac users won’t have to worry about, but that doesn’t mean that OS X is entirely immune to the potential nuisance, and nobody likes it when their browser has been hijacked by that type of junk. If you’re at all concerned about adware impacting your Mac and web browsing, you can easily scan, detect, and remove some of the most frequently encountered (although still rare) adware found in OS X using an excellent free utility called AdwareMedic.

Users who require higher than usual security measures often set a firmware password on a Mac, which requires that a password be entered before the typical OS X boot sequence begins. While these low level passwords are quite secure, but that higher security also means a forgotten firmware password can be a significant problem. Nonetheless, if you wind up in a situation where you or another user has forgotten a low level firmware password on a Mac, don’t panic, because you may be able to recover the password or bypass it using one of the methods outlined below. If all else fails, Apple can possibly help you too.

Many Mac users rely on the Messages app to converse back and forth with other Mac and iPhone owners, but unlike saving a picture or image from a message in the iOS side of things, Mac OS X Messages app does not offer a share sheet download option or menu for saving specific photos and media sent back and forth. That’s because the Messages app in Mac OS X offers perhaps an even easier and faster way to save images from your message conversations, using a simple drag and drop trick.
