Mac OS X 10.6 Snow Leopard
Two steps forward, one step back
Written by ML from Montreal
1/10/2009
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
2/10/2009
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

Playing nice with other software
Written by EH from Minster

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. …More508 of 602 people found this useful

Bad idea to Upgrade
Written by SR from Chicago
24/11/2009
Moved from PC to Leopard and loved it.. Upgraded from leopard to SL and I hate it!!
face recognition does not work in iPhoto.
Apps are slower than expected.
did not see any noticeable performance increase just the annoying beachballs and repair permissions issues.
Hard drive seeks are higher and HDD is noiser.
Battery life has decreased drastically.
No noticeable improvements even in 10.6.2
You'll end up spending more time fixing the OS than using it !!! Not worth the upgrade. …More4 of 7 people found this useful

Mac OS X 10.6 Snow Leopard
Bug in Address Book
Written by SB from Clark
24/11/2009
I don't have an opinion about Snow Leopard yet, except to say it was easy to install and appears to be a worthwhile improvement over Leopard.
I'm writing this review to warn about a "bug" in Address Book that might cause the loss of data.
I installed Snow Leopard 10.6.2 on my iMac (Intel 2.8 GHz, 4 GB, 24"). I typed some characters in the Note section of an existing Card in Address Book, then hit "Return", then hit "Tab". All existing characters became highlighted in the color blue, and all existing characters then were deleted when I hit the next key (any key). …More2 of 4 people found this useful

Mac OS X 10.6 Snow Leopard
Install with your eyes open!
Written by JL from london
24/11/2009
A whole load of different reviews here, but I think many of them are based on upgraded as opposed to clean installs.
I did a clean install for my MBP Unibody and imediately ran all the software updates. Only then did I install 3rd party apps that had Snow Leopard versions, and downloaded newer ones if they did not.
Anything that was installed WITHOUT a specific Snow Leopard compatible installer needs to be treated with a pinch of salt - it will probably be buggy until updates are made.
So far (using since a week after it came out) - I have had no crashes.
Pros: Runs well - obviously optimised for newer/faster hardware. Boot/shut down times greatly improved.
Cons. Quicktime X is a step back from 7 Pro. Safari a bit flaky.
Verdict: If you have leopard runing well with lots of 3rd party apps, there is not much incentive to upgrade, until the OS is more established. …More3 of 7 people found this useful

My Mac is still with the Mac OS X Tiger, can I upgrade to the snow?
- Asked by FI
- 30/09/2009
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
- 30/09/2009
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
- 11/10/2009
Best Answer
In my opinion, research the programs you are going to use most frequently and see if there is any mention about them being upgraded for snow leopard, many applications have been upgraded already, and more are on their way. It's entirely possible that most, if not all of the applications you use have already been upgraded and are ready to use. If not, wait a little while, or find a replacement product from a company that responds faster.
At the very least, the apps that have been upgraded already tell you a bit about the efficiency of the company you received the software from, and tells you if you can rely on them for speedy updates or not, which is often one of the most important parts of any software company.
And with that said, many applications that worked for 10.5 (Leopard) will work fine on 10.6 (Snow Leopard) such as Firefox, VLC, and various messenger apps, so also look up if the application doesn't need to be upgraded at all, perhaps it works as it is.
Hope this helps. =) …More- Answered by DS
