Why every Mac owner should use Fast User Switching

By Rob Griffiths, Macworld |  Software, fast user switching osx

You're probably aware that OS X is powered by Unix at its core. This core brings a lot of geeky technologies, like memory management and multitasking, that help make the OS X experience so pleasant. But it also brings something else, something with tangible benefits to any Mac user: multiuser support, and the ability to quickly switch between those multiple users.

If you're a parent, you may already be familiar with multiuser support in OS X; you've probably created a kids' account, and set it with the appropriate Parental Controls. (If you haven't, you should, but that's another story.) But if it's just you using your Mac, you may be thinking, "Why do I need multiuser support?" The answer is that there are lots of good reasons to use OS X's multiuser support, even if you are just one person on one Mac.

Multiuser and fast user switching

First, the technicalities. While this isn't a tutorial, OS X's multiuser support can be found in the Users & Groups panel in System Preferences; if you click the Login Options button, you'll see a toggle for showing the fast user switching menu, and in what form you'd like it shown. While multiuser support is the core feature of interest, it's the fast user switching capability that really takes the cake--especially in OS X 10.8 (Mountain Lion), where the switching is incredibly fast.

With fast user switching, additional user accounts are but a few mouse clicks away: Mouse up to the menu bar, click the Fast User Switching icon, and choose the account you want to use. Once that's selected, the process of switching takes something under two seconds, regardless of how much stuff you have open in any of the accounts.

Why use multiple users

Great, so you can quickly switch accounts, but why would you want to, especially if you're just one user on one Mac? Here are a few possible instances for using multiple accounts, beyond the parents-with-kids scenario.

Troubleshoot issues: If you're experiencing issues with an often-used application, you may wonder if the problems are being caused by some add-on program you just installed, or something else that's conflicting with that application. Creating a clean "test user" account is a great way to isolate such issues. Don't install any of your usual third-party add-ons in this test account; leave it as plain as you can. When an app misbehaves, switch to your test account, and try it there. If it works fine, you now know the problem is something in your "normal" user account. If the app has issues in the other account, too, then the problem is either systemwide or specific to the app.

Run as a non-admin user: The safest way to use your Mac is as a non-admin user. However, this can be a pain if you need admin access regularly to install apps or otherwise work with system files as a non-admin user. Consider creating an "Admin Only" account with full admin rights, and leaving it logged in. Then log in to your normal user account for your routine work. If you find you need to do some admin work for a while, fast-switch over to the Admin Only account. (Obviously, if you only occasionally need admin access, it's easier to provide the admin username and password when prompted.)

Give presentations: If you give presentations using your Mac, a presentation account is a must-have. No need to let your audience see your messy desktop, or the contents of your hard drive. Create a presentation account, and use that account when presenting. That way you'll show no messy desktop--only the stock OS X files you want your audience to see.
