The launch of Mac OS X Leopard has generated a lot of discussion in our Forums resulting in 8015 new posts on Friday. This comes second to the previous one-day record of 8143 posts that was achieved on iPhone launch day.
To organize this volume of posts, we've split the Mac OS X forum into:
- Mac OS X
- Mac OS X Help and Troubleshooting
- Mac OS X 10.4 and Earlier
- Leopard Meetup Events
Please direct your posts to the appropriate forum.
Here are a couple of solutions to some early problems:
- Solution to the "Installer Blue Screen" hang - blamed on Application Enhancer
- Solution to Hard Disk not appearing on Install "Choose a Destination".
- Tips from Apple for iChat backdrop effects.
- Apple has already issued a Software Update Login & Keychain Update 1.0 which addresses issues with old account passwords, connecting to some 802.11b/g wireless networks and FileVault password changes.
- Guide: List of Apps not compatible with Leopard
