It just works. Usually.

With the amount of bugs that are reported in Leopard and now Snow Leopard, I'm pretty happy to stay using Tiger. Unlike if I was stuck on XP, it doesn't feel like an outdated OS.

It has some many instability issues I had to take it off of both my MacPro and my MacBook Pro.

Hangs, and application crashes so frequent I couldn't work. Apple Care said, gee, were aren't experiencing any problems like that.

My MacBook Pro would get kernel panics just sitting there doing nothing. Yikes!

So I restored with time machine to 10.5.8, and my machines are stable again.

Come on Apple, don't go down that road. I switched from Microcrash to Apple for a reason, it works, it's simple, and it enables me to be more productive. Foul that, and the value edge is gone.

I did a clean install and the only problem I've had is the trash takes forever to delete. I had a minor issue with my printer, but was easily fixed.

As for software, I finally got rid of all Microshit and either downloaded open source or bought Apple products. Any others were added when the developer updated it to work with SL.

I'll say this has been the best Mac OS I've used in years! My 2 yr old Macbook seems like a faster computer now.

iPhone 3.1 "update" - Hah

My phone (3G 8G) has slowed beyond recognition from before the update. I have even removed some apps in an attempt to rectify it and even ran it for a weekend completely clean.

In addition I have a problem whereby the body of messages in mail are not rendered unless you go to another message and then come back.

I am very disappointed by Apple releasing this clearly under tested update.

At first I thought it was basically little different, maybe a little quicker.

It has (for me) basically broken preview.

Opening multiple pictures no longer works (opens two in separate windos and no more).
Contact sheet view in preview hangs / is MUCH slower than before.
Slideshow button has gone from the top bar.

Also iTunes seems really slow when un pausing, so much so I often end up pressing the play/pause button again and then it stops as soon as it starts.

I am sure there are loads of things I havent found yet, not looking forward to that.

For the record it was a clean install + migration on a Mac Pro.

Software is complicated. To expect a major re-write, Snow Leopard or Vista, to work flawlessly on every single computer is ludicrous. Apple is lucky they only need to worry about poorly written apps or drivers but they keep there hardware list pretty small. Microsoft has to worry about all three problems which is why it makes sense for a large public beta because they can't test every configuration. Apple has such a small hardware footprint to deal with they could almost have a room with all the version to test on. Applications and drivesrs are far to numerous to test. Expectations and habits need to change. People should not expect that they can upgrade there production/everday machine and have it work flawlessly the day the OS is released, no matter what OS your running. We also need to stop saying, Apple and Microsoft included, just upgrade your computer and everything will be fine. The complexity and sheer amout of crap that we have on our computers today requires that all major OS releases be installed on a blank drive and then manually re-installing and recopying our data back to the new OS. If you don't "have time" or "have a backup solution" then I would say there are other problems needing to be addressed before you jump into the next major release. A proper backup solution always afords you a way to easily do a blank drive install of your OS and manually rebuild it. Without a backup your asking for trouble anyway.

I would like to see TUAW see why Parallel thinks they are the Micro$oft of VM. I "MUST" buy version 4 to upgrade to snow leopard. Does anyone else feel this is BAD business?

I bought the family pack the day it came out and upgraded 4 machines including my work machine. Two other co-workers bought and upgrade their machines as well. The only issues that we've encountered were related to 3rd party software that needed to be updated or are in need of upgrades. Safari eats up memory and crashes but looks to be an issue with Webkitplugin Host dealing with Adobe Flash.

I have never done an upgrade install over another version of OS X before but I must say that this has gone better than any upgrade I have done on a Windows PC. I don't believe that Apple should be responsible for when 3rd party vendors software and every users software configurations. Hell, I support Windows at my job and I don't expected MS to be responsible to changes that a user makes on there machine. Most of the problems listed by the readers can be fixed by simple updates. Configurations maybe a little more difficult to fix without doing a clean install.

I remember people having problems with Leopard when it first came out. It was related to 3rd party software.

I believe that all OS upgrade have some pain involved no matter who's it is (Apple, MS, etc.).

I did an update install and had the mail app can't send problem which was fixed in 10.6.1. Then found the battery charge problem, fixed with shutting down the 'puter, press the on button with the left-hand shift, ctrl, alt keys pressed, then release all keys/buttons, wait 5 seconds and then power on. Then found I can't connect to the smb servers at work - so far no work around/fix for that which means my mac is a bit of a door-stop at the moment. Oh yes, this is a(n) unibody mbp, few weeks old. In my experience going from 10.x to 10.x+1 has always been like 1 step forward, 3 steps back until at least the 3rd patch. But I still rush out and get the new version immediately...

Cheers,

I have a Unibody MBP 15 inch (5,1) and so far I had zero issues with SL. As a matter of fact after trying it for several days in 32 bit kernel mode, I swtched to 64 bit Kernel mode and been running very well. Now I run in full 64 bit more 100% of the time.

One has to look at what they have installed on the system before blaming the OS.
