Some of your software won't play nice with new kitty.
Diehard Mac users today will be joining the latest and greatest operating system from Apple as today Mac OS X 10.6, also known as Snow Leopard, starts selling at retailers worldwide.
While Snow Leopard isn't an entirely new operating system from the ground up, as with any new version jump, there are bound to be some incompatibilities. As listed on the Apple Support site, the following applications don't play nice with Snow Leopard:
• Parallels Desktop, ver. 2.5 and earlier
• McAfee VirusScan, ver. 8.6
• Norton AntiVirus ver. 11.0
• Internet Cleanup 5 ver. 5.0.4
• Application Enhancer ver. 2.0.1 and earlier
• AT&T Laptop Connect Card ver. 1.0.4, 1.0.5, 1.10.0
• launch2net ver, 2.13.0
• iWOW plug-in for iTunes ver. 2.0
• Missing Sync for Palm Sony CLIE Driver ver. 6.0.4
• TonePort UX8 Driver ver. 4.1.0
• ioHD Driver ver. 6.0.3
• Silicon Image SiI3132 Drivers ver. 126.96.36.199
• Aperture ver. 2.1.1 and earlier
• Keynote ver. 2.0.2 and earlier
• AirPort Admin Utility for Graphite and Snow ver. 4.2.5
• Parallels Desktop ver. 3.0
• VirusBarrier X4 ver. 10.4.4 and earlier
• SPSS 17 ver. 17.1
• Director MX 2004 ver. 10.2
• EyeTV ver. 3.0.0 to 3.1.0
• Ratatouille ver. 1.1
If you have one of the above software and plan on upgrading to Snow Leopard, Apple suggests that you look for a newer version or an alternative.
Perhaps the biggest incompatibility of all is Snow Leopard's requirement of an Intel processor, leaving all of those still running Power PC processors having plain old Leopard as their final destination.
