It seems that despite concerns about application compatibility, it seems that the launch of Mac OS X 10.6 Snow Leopard has been a smooth one.
Over the past few days I've been keeping a close eye on the Apple support forums and while there are plenty of issues being raised by folks who have made the switch, there doesn't seem to be any sign of any serious issues plaguing this latest OS release.
The biggest single issue seems to revolve around HP printers/scanners not working after updating the OS. Some unofficial fixes are beginning to emerge but they don't seem to work for everyone or all devices. Seems like HP fouled up with Snow Leopard and is now having to endure a fair bit of well-deserved criticism. Still, on the scale of things these issues seem minor. Actually, it seems that the real issue here is that folks aretrying too get unsupported hardware working. Seems that HP is supporting more hardware than ever in Snow Leopard. Kudos to HP on that!
Like I said, there seems to be a myriad of minor issues, but whether these are down to Snow Leopard or individual systems (and users) it's too early to tell. Gut instinct tells me it's down to individual systems.
[UPDATE: This in from HP's PR folks:
HP has worked closely with Apple on Snow Leopard compatibility since 2008. At launch, there was built-in print driver functionality for more than 1,300 worldwide HP peripherals - the most ever offered by HP for a new Mac OS - from all HP product lines included in Mac OS X v10.6. New for Snow Leopard, HP is also providing scan support built into the OS for the latest HP inkjet All-in-Ones; customers will not need to download or install additional software.
Customers can access a full list of HP-supported printers at: http://support.apple.com/kb/HT3669. In addition, HP recently announced that company experts will provide real-time support for customers who have recently upgraded to Snow Leopard. On Sept. 9, experts from the HP Mac-connect team will monitor the HP Mac Printing & Scanning Board <http://h30434.www3.hp.com/psg/board?board.id=Macintosh> on the HP Support Forums to help customers enjoy full functionality of their current Mac-compatible HP peripherals. Customers can visit the board and post their questions now, with real-time service beginning next week.]
