The Mac Notification Center gained widgets in OS X Yosemite, which are revealed when the Notification Center is opened and the “Today” view is chosen. This looks and functions a bit like Widgets in iOS, and these widgets range from World Clock, Calculator, Weather, Reminders, Calendar, Stocks, Social, and an to an iTunes widget, but they can include third party widgets that came bundled with other Mac apps too. To get the most out of Widgets in Notification Center, you’ll probably want to customize which widgets are shown or hidden to better suit your needs and preferences.

The Instant iPhone Wi-Fi Hotspot feature in OS X is incredibly useful if your Mac is on the go or you need an alternate internet connection, but even if you’re not aiming to use the cellular internet sharing capability of iPhone there are some other handy uses for the feature, like checking two of your iPhone vital stats without having to pull the device out of a pocket or purse. As long as Instant Hotspot has been set up and the compatible Mac and compatible iPhone are nearby one another, you can remotely check on the battery life and cellular signal strength of that iPhone right from the Mac with a quick glance, even if the iPhone and Mac are in different rooms.

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 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.

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.
