Snow Leopard review

But underneath the customary OS X fit and finish there's a lot of new plumbing at work here. The entire OS is now 64-bit, meaning apps can address massive amounts of RAM and other tasks go much faster. The Finder has been entirely re-written in Cocoa, which Mac fans have been clamoring for since 10.0. There's a new version of QuickTime, which affects media playback on almost every level of the system. And on top of all that, there's now Exchange support in Mail, iCal, and Address Book, making OS X finally play nice with corporate networks out of the box.
So you won't notice much new when you first restart into 10.6 -- apart from some minor visual tweaks here and there there's just not that much that stands out. But in a way that means the pressure's on even more: Apple took the unusual and somewhat daring step of slowing feature creep in a major OS to focus on speed, reliability, and stability, and if Snow Leopard doesn't deliver on those fronts, it's not worth $30... it's not worth anything. So did Apple pull it off? Read on to find out!
Installation

Installation itself took about 45 minutes on most of the machines we tried, although we did run into some snags once things were complete. We didn't have any problems with the more pristine MacBook Pros in our fleet, but one of our production machines is a cranky older iMac that's been in constant use for over two years without a system rebuild, and when it restarted the desktop pictures were all set to the defaults, the System Preferences app wouldn't launch from the Apple Menu, our MobileMe sync states were a little confused and Spotlight began reindexing all the external drives. Fixing these problems didn't take much, but if your machine is already acting up don't expect everything to go perfectly.
Other installation notes: We were promised 6GB of storage savings with 10.6, and Apple more than delivered -- we got anywhere from 10GB to a whopping 20GB back after installation. Rosetta is no longer installed by default, so if you're still rocking some legacy non-Universal apps you'll want to make sure and install it. Printer driver installation is much smarter, installing drivers only for those printers you've used in the past and printers that appear on your local network. We have no idea why Apple continues to insist on installing language translations by default, but they're much smaller now at 250MB.
Overall, installing Snow Leopard is just like installing any other major OS update: it works great, except when it doesn't. The process itself is fine (in fact, Apple has even built in some safeguards to let you pick up an install if your computer dies or is shut off half way through), but it's the little kinks you have to work out afterwards that can be tricky. If you haven't loaded up your system with hacks and tweaks chances are you'll be fine -- and if you're living on the edge, well, you're probably used to doing some extra work around upgrade time.
UI enhancements
Dock Expose

Stacks
We've never been huge users of the Stacks feature, but it's been tweaked and is much more usable in 10.6 -- as long as you're using grid view, which is now scrollable and offers the ability to drill down into folders just like a Finder window. All the other views are essentially the same -- and for whatever reason, dragging a file onto a stack icon doesn't open the stack, but instead opens a Finder window. While we're on the subject of folders in the dock, explain this nonsensical operation to us: command-clicking a stack icon doesn't open the folder (as you might expect), but instead pops open the enclosing folder. This counter-intuitive (and frankly frustrating) glitch has been around since Tiger -- and we have no idea why. Here's some video:
Finder file previews
We'll get to the big Finder changes shortly -- the Cocoa rewrite definitely improved things -- but the big UI tweak here is live file previews. That means you can watch a video, flip through a document, and generally peek at things without having to open an app or even hit the space bar for Quick Look. It's quite handy -- but again, not earth-shattering.

Notable app changes
Finder

QuickTime X

That said, there are some notable changes with QuickTime Player: there's a new screen recording tool (we made all the videos in this post with it), you can record right off your built-in iSight, and there's a new iPhone 3GS-like "Trim" tool to cut your videos fast.
That glossy title might come at a steep price for some of us -- at least at first glance. QuickTime Player X has certainly added some welcome new options for most, but for QuickTime 7 Pro users, things get a little confusing. If you've already got Pro on your system and do a straight install, you'll end up with the standard new QuickTime -- which means a lot of what you're used to will be missing. Hell, there isn't even a preferences dialog -- so say goodbye to presenting movies on a different monitor, or choosing a default full screen setting. The changes also means that you can't do quick'n'dirty edits by copy-and-pasting anymore (a favorite of Engadget editors), and export options have been reduced to presets for iPhone, iPod, Apple TV, MobileMe, and YouTube.
On top of that, some QuickTime-dependent apps seem like they need a rewrite to work correctly -- we couldn't get our Turbo.264 HD stick to function, and other QuickTime programs we tried seemed similarly stressed. Oh, and those screen recordings? They're encoded with some combination of H.264 and AAC audio that didn't play nice with Viddler out of the box -- and YouTube's uploader refused to load under Snow Leopard (we had a number of server errors), so we ended up uploading all these screencasts from a Windows machine. That may not be the case for all, but it was for us.
This won't be too much of an issue for users who are sticking with the basic QuickTime functionality, but for those of us who've become accustomed to Pro, it may be a little shock. Interestingly, Apple let us know that you can actually re-install QuickTime 7 Pro from the Snow Leopard disc (and from your Utilities folder, oddly), but if you hop right into a standard upgrade, it's amazingly easy to miss (we did on multiple systems).
Safari 4
If you're thinking of upgrading to Snow Leopard on day one, chances are you're already running Safari 4, since it's been available since June. The big changes in 10.6 are (obviously) 64-bit support, which here translates into much faster Javascript performance, and a new browser plugin architecture that runs individual plugins as separate instances. That means if a plugin like Flash crashes it won't take the whole app down with it, but sadly, we weren't able to test it -- for maybe the first time ever, we couldn't crash a browser. Hopefully our good luck rubs off on you.
Exchange

Compatibility
Here's where it gets a little rough. Although Snow Leopard is ostensibly just a polish and repair job on Leopard, there've been enough changes under the hood so that plenty of things are likely to break -- or at least not play nice. As with the installation, if you're running a stock or close-to-stock system, you probably won't run into any problems, but if you've got a setup as tweaked as most of those in the Engadget labs, you're going to run into some issues.

We also noticed problems with old standbys like Growl, GrabUp and Skitch -- really clutch go-to applications that seemed to buckle under the 64-bit noise. Although we could start them in 32-bit mode, nothing seemed to work exactly right, and we're pretty sure we spotted Growl making off with a ton of free memory when we weren't looking. We also had trouble getting our Sprint Novatel U727 3G stick working, although our Verizon card was fine. Again, we're sure all of this is going to be updated, but if you're like us, the bugginess will prove maddening at times -- enough to make us consider waiting out the upgrade on some of our other machines.
There were some other head scratchers we saw on various systems, too. On a 17-inch unibody we were putting through the paces, the WiFi inexplicably has gone out and we have yet to get it working again. On a 15-inch, older generation MacBook Pro (3,1), Spotlight will only fetch search results in the dropdown -- results in a Finder window come up empty. More annoyingly, on two other, newer models we were testing with, Safari crashes out when booting into 32-bit mode -- meaning even Apple's workaround doesn't seem to... er, work.
That's the bad news, though. The good news is that almost all of our regular, non-plugin, non-third-party-framework, non-hack apps worked just fine. Office, Photoshop CS3 and CS4, Tweetie, Firefox 3.5, Ableton, Fluid -- you name it, it ran without a problem. Like we said, if you're running things close to stock you're going to be fine, but we tend to kit out our rigs with a ton of little hacks to really speed up our workflow, and that's the stuff that's broken in Snow Leopard. It's up to you to decide where on that line you fall before you commit to the upgrade.
Overall speed and stability
Compatibility with our various hackeriffic plugins aside, we found Snow Leopard to be just as stable and free from major hang-ups as Leopard. That cranky iMac we installed it on seemed to perk up a little, and while we don't think anything will ever make Firefox feel perfectly stable, we certainly didn't experience as many beachballs or other hangups while running 10.6. So yes, subjectively things seem fast and reliable, and the new Finder makes day-to-day usage seem positively zippy -- and the objective benchmarks tend to back that up.

As measured by XBench, Snow Leopard affects every Mac a little differently, but the basic outcome is the same: raw CPU performance goes up slightly, while the graphics numbers go down -- OpenGl performance in particular takes a big hit. We're not sure if this is due to our version of XBench not playing nicely with Snow Leopard or something else entirely, but we didn't notice any slowdowns while we actually worked -- or played a little casual CoD4. We're not deep into the benchmark scene, so we'd wait for some hardcore marks to hit before you race into fanboy battle with these numbers -- for now, just know that Snow Leopard certainly "feels" a little snappier than Leopard.
Wrap-up

Update: In the original version of the review we noted that QuickTime 7 Pro wasn't available for Snow Leopard. In fact, the software is available as a separate install on the disc itself and via the QuickTime 7 app in the Utilities folder.
























where it says -boolean YES, change it to -boolean NO and it should go back to normal
snow leopard freed 18 GB of memory on my MBP
how do you get that dark dock?
@woody
yes, I am. And thats why there is a TASKBAR on top of the screen. Also, it's been almost two months, zero crashes; Snow Leopard ensures crashes are preventable.
Marketing FAIL: http://webologyworx.com/mac-snow-leopard-marketing-fail.html
First off.... WOW... that price is unbelievable. I didn't ever expect to see it that low. Thumbs up, Apple!
Second, muchly improved performance... if you have a Core 2 Duo or higher. I really didn't see much of a change on my 3 year old Mac mini. (Guess it's time for a new one.) That has a Core Duo on it. But, still functions nicely.
Some of the new features they put in there are just for design enhancements. Takes a little getting used to, but nothing I can't learn.
I was surprised that World of Warcraft: Burning Crusade was able to launch and run. Nary a glitch or a hiccup.
Only one problem. Pro Tools... can we hurry it up with system compatibility?
anyone know were you can get the bright white leopard wallpaper with all the blood on it?
Hi
I installed snow leopard on my macbook(not new aluminium one) yesterday.
Few things i have noticed:
Battery Life- after a full charge with a few programs running i used to be getting just short of 2 hours. I am now getting over 3 hours in the same scenario!
Start up and shut down time - Much Much Much quicker. Especially the shut down time! So fast!
The hardware - I am usuing the iStat Widget on my dashboard:
-My battery health has gone from 94% up to 97%.
-My CPU was working its arse of nearly using 80% most the time now practically nothing.
-This has meant the temperature of my CPU has gone down from around 72 degrees to 48 degrees. :O incredible.
-MY FAVOURITE the noise coming out of the hardware eg fan. was nearly non stop soon as more than one program was in use it would be really! really! noise! now i can watch a movie have facebook going and also be browsing through itunes not a peep out of it.
-Lastly for hardware THE HEAT!! the from the bottom of the macbook was horrible before snow leopard! now like i said with programs that really push it no more heat issues!
Expose and Control Click Menus - simple slicker and smoother.
Program opening times- FASTER FASTER FASTER!
In summary it does everything it says on the tin! Its a faster better improved leopard! The healthy hardware alone has to be worth £25 and only a fool would turn it down for that price!
A MUST BUY FOR MAC USERS!
"Other installation notes: We were promised 6GB of storage savings with 10.6, and Apple more than delivered -- we got anywhere from 10GB to a whopping 20GB back after installation."
Are you sure that this is not because Snow Leopard now uses powers of ten instead of two?
Leopard: 1 GB = 1024 MB = 1024*1024 KB etc.
Snow Leopard: 1 GB = 1000 MB = 1000*1000 KB etc.
I actually think that's true, it's not physical space your getting back but the software reports it as more.
I think they should rename the product Slow Leopard!!
It's a fast installation, but now I'm always see the little color wheel spinning, as it's process. I've also had to force quit more. If I wanted a slow crappy performance I would have bought a windows laptop at half the price, not a MacBook.
Am disappointed so far.
I just discovered a cute, yet useful, animation effect in Preview sidebar.
(a) select some PNG, JPEG, GIF images and a couple of PDFs (need at least 1 multi-page PDF)
(b) COMMAND O to open all of these documents in Preview (icons are displayed in sidebar)
(c) The multipage PDF will have a 'Heads up" arrow on page 1 of the PDF
(d) Click the arrow to open/close the pages in the PDF document (lovely animation of transparent folder cover opening and closing)
Cute and useful.
I like it.
So when is someone going to make this work on a ps3?
I am running both Snow Leopard and Windows 7 RC on my MacBook Pro and I have to say that the changes that I have noticed in both operating systems are worth the upgrade if you are using the previous OS release. Windows 7 is not quite ready to beat XP pro yet.
Snow Leopard has quite a few very welcome changes, Spotlight is noticeably faster, the Finder in General is Faster, QuickTime X,Dock Exposé, the Airport Status Menu icon changes, I am thoroughly impressed with it since I installed it on the first day that it was available. For $30 I will never complain about the price to upgrade OS X, the Previous upgrade from 10.4 to 10.5 was $129. To those who say that a switch from 32bit with support for 64bit applications, to a 64bit throughout OS is a trivial update please go to your nearest college and take a programming class or ten, rewriting a kernel is not something trivial. I got quite a bit of drive space back, and the system is faster all around. It gives older Mac's with compatible hardware a new lease on life.
Windows 7 Ultimate RC - It is amazing how dock like the new improved task bar is. It is still no dock, Backwards compatibility with other older windows OS's is great, being able to select which service pack of XP you want your older video games to run under is even better. It is performance improved over Vista but XP pro still keeps it gasping for breath while trying to keep up.
WOW! This looks great, can't wait to try it. But I wonder if it will have any effect on my hardware. Last time I did an upgrade I had problems finding drivers for my bt headset and I ended up giving it away. On my search for a new one I found this future release .http://www.budsgoblue.com/ I can't seem to find any info on them. They look pretty cool but no info on the manufacturer.
It's noticeably faster and the installation is very smooth. Just one snag- it wiped out my mail files (but I had a back up and put them in again and it worked fine after a re-start).
Anyone other than me see a rather hefty speed decrease with Snow Leopard? Simply changing desktops using the keys I've setup (Left Control+Cursorkeys) is much slower. I don't remember it lagging behind my keystrokes this badly.
And, dragging a window between desktops when Spaces is enabled is horribly slow. The window lags behind the mouse by seconds. Nobody else has this problem (I've seen this on an iMac with 4G RAM, and 2009 MacBook Pro with 8G RAM)?
And where's the little arrow that trailed behind you in the desktop matrix as you changed from one desktop to another? No biggie, but I miss that little UI detail.
Here's at least one person who wish they had not upgraded.
I've been using the update for a few weeks and wish I would have waited a few cycles. I use a plain vanilla setup on my MacBook Pro but I use VMWare Fusion. My problems with Snow Leopard are that is the dock icons disappear, the mouse pointer disappears and Firefox crashes on Google mail file uploads. All of these issues are new for me. I'm confident Apple will iron everything out over time but these look like first-generation bugs.
Hmm, you SAVE hard drive space now with this new version becuase they not install all the items that the older version did. And they call that a FEATURE of this new "version"?
If I not install all the items when I installed Vista from XP Pro I would have saved hard drive space too.
Nice review.
Quick suggestion though for the narration of those videos: Could you speak a little clearer/louder? Your voice gets really low and mumbly at some points and I lose you.
How did you get the 'Novatel U727 3G stick working' resolved?
I'm still having difficulty with mine (through Bell in Canada) and will ultimately have to demand a reimbursement for a service i cannot use (for over two months now).
I don't understand the performance graph. What is the number on the vertical axis? Is this a percent increase in speed? If it is some sort of score, how does it compare previous to update?
Linux is free, Windows 7 is the only OS worth buying
What a fanfare.....
This kind of OS's exist for years.
Anybody heard about DSL for example? it's a 30Mb Linux-powered OS that runs Firefox among many other things. Loads in seconds, anywhere.
sorry wrong thread... ignore that msg please.
