Ask Different is a question and answer site for power users of Apple hardware and software. It's 100% free, no registration required.

I would like to call for a place to list some little things that surprise you about Lion. There are so many articles and lists of all the new features with information overload, I would rather focus this spot of the site on tiny delights with a note why it makes a difference to you.

Please one topic per answer, this isn't a race to enumerate everything that changed. This isn't the place for massive topics like the implications of FileVault 2 on your entire workflow - just a stroll past some little gems, fun oddities or subtle changes specific to Lion.

Answers must relate to why or how you use the feature - links to official tips and tutorials are great, but the intent is to collect little gems that affect how the system gets used. Expect answers that are not specific to lion or lack a personal use case to be heavily edited or deleted.

Using the FaceTime camera to add signatures to PDFs in Preview.

Click the annotations button in the toolbar and use the drop down menu next to the signature icon to grab your signature from a piece of paper you have written it on. Then just click and drag in the document to place it. Haven't really needed it yet, but it's implemented so nicely that I did it just for fun.

Finder - make a new folder with a selection of files

Accessing accented characters has been made a lot easier.

Just hold down the letter and a list of alternatives will show. Awesome.

Example of OS X Lion accented characters popup menu

By pressing the number and continuing to type, the desired letter replaces the e and alows you to keep your fingers on the keyboard. Double Awesome.

This behavior can be turned off. Turning off this new feature allows the traditional key repeat function to work for all keys as shown in the keyboard system preference window. keyboard

System Information is more visual and speedy

System Information in Lion (which used to be System Profiler in Snow Leopard) has gotten a facelift and a tune up. The information is presented in a much more usable and graphical format. Memory pane in Mac OS X 10.7's System Information

In addition to the facelift, the launch time of the app is optimized to be immediately responsive, delaying any lengthy discovery hardware and software until you ask for that level of detail.

This makes it much more useful to hop in and copy your serial number without waiting for the app to finish launching an inventory of all software on the mac.

All window edges allow resizing

How about ability to resize windows from all edges of the window?

The reduced clutter of not having a resize nub is nice, but the power comes with these options (which can be combined):

  • shift - maintains aspect ratio while sizing
  • option - maintains the center point while sizing

And you can hold shift while resizing to maintain the aspect ratio, and alt/option to anchor the window at its center, and both for a combination –  Jonathan. Jul 24 '11 at 1:41

@Jonathan That makes it stand out; Windows had edge resizing for some time now. Windows 8 will probably have aspect ratio resize! –  Thaddee Tyl Aug 1 '11 at 9:40

Stateful Terminal app

When you quit Terminal.app and re-open it it not only re-opens previously opened tabs (without restarting the commands that were running in it, of course), but it shows you the last 500 rows that were output in the closed terminal window.

This has two major advantages to me:

  1. I have the same history in the same tab as I had it
  2. Seeing the old output helps me bring the tab back to the state it was in.

tmutil is a command line interface into Time Machine.

time tmutil startbackup --block is full of win.

You can now start a backup, time how long it takes, and know how much data was saved, all from the command line!

You can flush your local backup store to free up disk space as well (or enable local backups if desired):

 sudo tmutil disablelocal
 sudo tmutil enablelocal

Managing Time Machine from the unix prompt is a bit of a geeky thing, but I wanted to call out this hugely useful tool that is hidden underneath the hood. Being able to analyze the difference between the current mac and the last backup with tmutil compare is also incredibly useful. Particularly useful in addition to managing the on/off and local/remote status of Time Machine, managing exclusion lists - these few commands seem particularly useful to me (and hence make me smile broadly, perhaps Lion-like):

  • calculatedrift
  • uniquesize
  • latestbackup

The man page is great and actually teaches how the backups work and encourage exploration of local storage, inheriting previous backups and much more. Someone deserves beers or better at the next WWDC.

Quicklook previews within spotlight search results

I usually use Launchbar so I don't rely on Spotlight results (top-right) corner of the screen, but when I do, I always hated that I couldn't quicklook or even see the path of the results. Now it's possible if you wait on a result for a second, you'll see quicklook:

enter image description here

Now try and combinations! With one you can see where in the file is the string located (like in the screen shot), and with the other you can see the file path.

Also using and the arrows will move through the categories.

Nice details.

I also like the addition of Control-Option-Space to bring up a search in a Finder window (which I use much more than Spotlight itself). –  Matt Gallagher Jul 31 '11 at 8:13

Login sheet for WiFi network TOS negotiation

Lion will open a little window immediately upon connection to a WiFi network that requires a webpage to 'agree' to any terms of service (TOS)

This really helps if you have apps that use http in the background like twitter since those programs might "receive" the agreement form and disregard it before we as the users know to open our browser and see the terms. Most routers will give up after sending the first terms causing a broken network connection for many users.

Also, as a bonus, WiFi is now called WiFi instead of AirPort.

It doesn't qualify as a tiny thing, per se, but since it came up in the comments...

Natural Scrolling

It took a couple of days to get used to it but now it really does feel natural: moving your fingers across the trackpad the same way you would move your hand if the content was on your desk (or iPad) fits and actually makes sense.

I know it's not popular with everyone but the only reason the traditional scrolling direction feels normal is because we're used to it; the scroll wheel on a mouse and the old trackpad response was about moving the scroll thumb in a given direction, not the content.

Even before Lion when I'd been using my iPad for an hour or two and then sat down with the trackpad on my Mac I'd end up using the trackpad wrong for a moment. Why couldn't I push the web page up if I wanted it to move up?

Me, I'm a fan.

Despite feeling like riding a bike backwards (something you can force yourself to do, but lack trust or good feelings about the change), I can see a month down the road absolutely abhoring "the old way". Moving something is simpler than moving a control that moves data underneath my fixed viewport. Challenging to adapt to this reversal, but I predict most will switch to "riding our bikes backwards" soon. –  bmike Jul 24 '11 at 19:34

It's a nice feature but I had to turn it off because it really messed me up when I tried to scroll on a Windows or Linux box. –  Ferruccio Jul 25 '11 at 12:59

I love it. Got used to it in about an hour. As for who to blame for the traditiona scrolling with mouse scrollwheel: most likely Microsoft. IIRC they came with first scroll wheels (brilliant idea), but, alas, did not think hard enough and mapped the wrong directions :) –  Rimantas Jul 31 '11 at 19:20

I donno, it was/is really annoying for me. On the iPad, stuff moves with your finger and you're physically touching it, so it this style makes sense. On the Mac, the monitor is actually perpendicular to your trackpad and the whole thing is disorienting and doesn't feel intuitive at all. –  Tejaswi Yerukalapudi Aug 1 '11 at 2:26

Clamshell Mode simplified for external displays

In Lion, if you want to use an external display with a closed notebook (also known as clamshell mode), you can do the following:

  • Attach the external display and power adapter to the notebook.
  • Close the notebook.
  • The external display stays on!

The process is much easier because Lion assumes that closing the notebook doesn't mean "put my Mac to sleep" if you also have an external display attached.

Lion also assumes that opening your notebook means that you want to use its display, so there's no need to manually force display detection.

In Snow Leopard, if you wanted to use an external display with a closed notebook, you'd need to do the following:

  • With the notebook open, attach the external display.
  • Close the notebook. Wait as the Mac goes to sleep, and the external display goes dark.
  • Wake the notebook from sleep (using an external keyboard or mouse) to activate the external display.

If you then opened the notebook so that you could use its display as well, you'd need to force the Mac to detect displays.

Woah. I thought this was a bug in Lion. Because, naturally, when I close the lid of my MBP, I want the secondary display to go off as well. Thanks for sharing. –  ayaz Aug 1 '11 at 19:42

Battery, Time and WiFi shown on Login Screen

The clock, battery charge level/status, and wifi status indicators that are now displayed on the Login Screen; three very useful pieces of information even when you're not yet logged in.

If you enable a hidden preference, clicking the time will show in order:

  • The IP address of the mac

Apps like Preview can quit themselves when not needed

Previously, when you opened something in Preview and you were finished with it, it was left running (in the background).

Now, when you close whatever you're previewing and switch focus to another app, Preview quits. This behavior of saving the work and/or closing the app when the last document is closed is a standard feature in Lion for many apps to use.

I'm a bit anal about keeping not required apps running, so was glad that has been introduced in Lion.

The system will quit apps too if resources are low

This is covered in detail at Lion is a Quitter from TidBITS, but the system will step in and automatically terminate apps which adds to confusion for people that pay attention or are habituated to the old way where users had to intentionally quit apps for them to disappear from the dock and app switcher tab.

Safari offers to set up Mail, Calendars and Chat

When logging into a Gmail account in Safari for the first time (and if that account hasn't been added to "Mail, Contacts & Calendars" in System Preferences yet), Lion will offer to add that account. Great attention to detail that made me smile.

Finder merging of folders and files

I must say that the most smile-worthy thing I have come across is the merge folders / keep both feature. I still cringe a little when I even think about dragging a folder named pictures onto another folder named pictures, but once I learn to trust it, I will be more willing to clean up YEARS of old documents scattered in creaky nested folders named "old" "cleanup" "2002" "Documents from old Mac" and such.

It is a little thing, but boy is it fun to feel like I have an intelligent tool to automate what I want to have happen - and not just having one folder overwrite the other as past versions of OS X felt was the best choice.

That might be the last feature I'll try in Lion. It's certainly well done and works like a charm, but 20 years of muscle memory will still prevent me for a long time from doing what I've always assumed to be a huge, unrecoverable mistake. Guess old habits die hard. –  Cyrille Jul 21 '11 at 13:12

Drag flocking:

One major "gotcha" is swiping will easily trash whatever comments you have entered into most web pages. Normally, the system warns you before navigating away from a text entry, but this swipe just undoes whatever you have done on most occasions causing you to lose work :-( –  bmike Jul 27 '11 at 18:34

Right clicking on dock icon gives a list of recently opened items.

Particularly handy for apps like TextEdit and Pages!

Also: If you activate Application Exposé, via ctrl+down arrow, or hot-corner, it shows the recent items as icons.

If you assign a mouse gesture to App Exposé (via Preferences - Trackpad - More Gestures), you can use it to activate App Exposé for any application in the Dock. Just hover over the app icon with your mouse and do the gesture. The application doesn't need to have the focus.

OS support for full screen apps!

I only have a 13" laptop, and when building iPad apps I never see the whole UI of the iPad in XCode - which is a slight nuisance. Now with XCode supporting fullscreen, that issue is less painful.

Also, Pages & Safari just look beautiful in full screen.

With Pages, if you have a second monitor, it will use that for palettes e.g inspectors, fonts and colours. Not all apps appear to support this yet, but it makes full screen much more sensible on multiple monitors. .

"Fullscreen" is an absolute nightmare for multi-monitor users. It completely disables any secondary or tertiary monitors. Fullscreening an app currently sends the app to the primary monitor with no option of changing it.

Doing anything when you make a window full-screen other than obliterating all secondary monitors is a non-trivial UI problem. For novice users — for whom full screen mode is surely mostly intended — it could quickly get very confusing. Apple doesn't implement features until it fully believes they are ready for prime-time; someday they will figure out (what they think is) the best way to do something useful in this situation. –  75th Trombone Aug 8 '11 at 20:03

The redesigned lock screen

The lock screen is a small, relatively unimportant thing that made me smile. (Quite literally, when I was asked for a photo at the end of set up.)

Mail.app is full of smiles and neat animations

It's gotten a VERY serious overhaul, and feels integral and integrated into the OS itself. For the first time since I started using my gmail account full-time, I'm not using a browser window to get my mail.

Tiny, unexpected, smile-producing behavior?

  • When you hit send, the message you've just composed whooshes up the screen and off into the internet.
  • The concertina effect when quoted text expands
  • animations when moving from grouped message to another (or grouping happens)

These little animations don't help the mail app do it's job, they help us see and visualize what is happening. Altering the age-old phenomenon of sending email isn't something I expected to enjoy, but I love it.
