Mac OS X 10.6 Snow Leopard

It delivers a wide range of enhancements, next-generation technologies, out-of-the-box support for Microsoft Exchange Server, and new accessibility features. It's the world's most advanced operating system, finely tuned from installation to shutdown.
Snow Leopard is an upgrade for Leopard users and requires a Mac with an Intel processor.
Upgrade your Mac experience.
With Snow Leopard, iLife ’09, and iWork ’09 all in one box, the Mac Box Set is the best way to upgrade your Mac experience, especially if you’re still using Mac OS X Tiger.

Mac OS X 10.6 Snow Leopard
Two steps forward, one step back
Written by ML from Montreal
Sep 30, 2009
The speed increases are significant, and probably worthwhile in the long run, but applications - Apple and non-Apple Intel applications included - crash fairly regularly. All the non-Apple applications have crashed several times since I started using Snow Leopard a few days ago, and Apple applications such as Mail, iPhoto, and Safari have also crashed. While the speed increase, and some of the layout improvements, make it overall a good product, the number of bugs means it's probably worth waiting for some updates before buying it. …More

Too many issues to bother with now
Written by AK from Kansas City

Luckily I had only had my computer for two months before I attempted this, because it was utter ____. I've lost a couple of things because I had to revert back to leopard, and Firefox was one of the main ones. My office 2008 is buggy now and I've tried to fix it, but I think its even past my help. My advice is to wait a few months, and back up your computer first if you do attempt it. Luckily I did. …More

Beware. If you are using Adobe Products such as CS4 or Nikon products such as Capture NX2. Snow leopard does NOT play real well. locks up (Beach ball of death) alot. Also Snow Leopard will cause your legit copy of Lightroom 2.5 to expire.
Other than that nice savings to the HD and noticeable speed increase. …More523 of 618 people found this useful

Has caused many problems on my Macbook Pro. I can no longer output to my TV in color. caused my battery's firmware to corrupt. Full of bugs and after a series of long phone calls to apple i've been informed that some of the bugs aren't even being looked into and they are not planning on fixing some of the bugs. Do not buy this, waste of your money I had to reinstall OS x 10.5 to get stuff to work right. …More

Mac OS X 10.6 Snow Leopard
Great for my MacBook Pro!
Written by RS from Hollister
Nov 25, 2009
I was a bit concerned about installing this product after reading many negative reviews here. However, I took the chance and am extremely happy with the results. My system does run faster just like the ads claim. I guess if you have an older system not running Intel dual processors, then Snow Leopard is not for you. If you have a newer system I highly recommend this product.
The only thing that doesn't seem to work right anymore is my 5 year old HP 2840 all-in-one laser printer. The scanner doesn't function correctly. It doesn't work with Vista either so I'm not too upset. This problem appears to have to do with the newer OS and the driver updates from HP's website have not fixed the problem. I guess it is time to buy a new scanner that will work with the new OS.
So if you have an older printer it might need to be updated or replaced to keep up with Snow Leopard. I knew about the HP compatibility issue before I installed Snow Leopard, but decided I would retire my old printer and invest in a new model that I can use on both platforms- OS X 10.6 and Windows 7. …More4 of 4 people found this useful

Mac OS X 10.6 Snow Leopard
MS Exchange Compatibility Worth the Price
Written by SW from Lincoln
Nov 24, 2009
I lived two lives for several years. Outlook/MS Exchange at work and Mac at home. While accessing my work accounts via the web was easy enough from the Mac, it wasn't fluid and was missing several features. Snow Leopard did away with my dual life. I was delighted with how easy it was to make the meld and the ease of direct access to my work account including my calendar and address book. I had no problems installing SL at all, and while I assume others are less than thrilled that there are no major changes, I contend that the devil is in the details, and Snow Leopard has done a great job of taking care of details. …More

My Mac is still with the Mac OS X Tiger, can I upgrade to the snow?
- Asked by FI
- Sep 30, 2009
Best Answer
As I said before - your processor - i.e. the age of your Mac is key to this. If you have an Intel processor (the newer Macs) - then yes you can install an upgrade to Snow Leopard 10.6, if not then no, you are stuck with Tiger 10.4.
Look on the Apple Store site for hardware requirements of Snow Leopard 10.6.
Apple stores do not sell older operating systems - such as Leopard 10.5 - you will have to get Leopard 10.5 if you want it from Ebay or somewhere similar. …More- Answered by JW from BEXLEYHEATH

My Imac is Mac OSX Version 10.5.8 Would I benefit by upgrading to Snow Leopard, or have I already got it.
- Asked by CW
- Sep 30, 2009
Best Answer
You have the most up-to-date release of Leopard, but not Snow Leopard. Snow Leopard is version 10.6 - you only have 10.5.8.
And to answer your second question, no, MS Word is not included with Snow Leopard - you have to buy it separately. It's about $150 US.
Hope this helped!

Lots of bad reviews. Should I wait to upgrade?
- Asked by AM from Hoffman Estates
- Oct 11, 2009
Best Answer
Reviews may say one thing and you might find out from your own experience another thing.
If you're speaking about upgrading to Snow Leopard, I suggest you look for an Apple store in your area and sign up for one of their free workshops on Snow Leopard.
While attending the workshop, you will find out more about Snow Leopard, and the person conducting the workshop will be able to answer some of your concerns about it.
Apple's workshops can be very helpful and informative. …More- Answered by CP from Golden Valley
