Updated October 9th, 2019.
Apple released the 10.6.2 Snow Leopard update and it fixes a whole lot of issues (click the link and start the download while you read). I had been waiting for this update before moving to Snow Leopard, and I’m glad I did. Apple had already put out the 10.6.1 update, but that didn’t address the problems that early adopters of 10.6 had been reporting. For those problems, we’d have to wait for 10.6.2, and now it’s here. Armed with the 10.6.2 update, I installed 10.6 on my original Intel iMac (the white one), and then the 10.6.2 update, and also the HP Printers update, and everything is great. Printing is fast again, the iMac starts up quickly, Mail’s loading speed is especially improved, and overall the iMac is running better than it was in 10.5.8.
If you have an Intel Mac of any sort and you’ve been waiting to install 10.6, now is a good time. There is always the chance that something that you use will not be compatible with 10.6, but if you make a backup first (please) you’ll be able to revert to 10.5. There’s a good list of compatible/not compatible programs at Macintouch.com– worth your time to check it out.
It is always better to download the “Combo Update” (linked above) rather than a simple Software Update. So do it that way if you can. In fact, if you already did the Software Update, download the 10.6.2 Combo update and run it.
Given the advantages of 10.6 over 10.5, and the super-low cost ($29), upgrading to Snow Leopard (10.6) is a smart move. The only question really was when to do it. With 10.6.2’s fixes in hand, the time to upgrade is now.
