Mac OS X v10.5.0 through v10.5.2 requested “SRV” records from DNS servers rather than the old standy “A” record. Craig Hunter explains:

When early versions of 10.5 tried to request an SRV record from these servers, some would be smart enough to reply with a “can’t do it” (triggering the OS to request an A record instead), but others wouldn’t respond at all. And so the OS would wait 30 seconds (default timeout for name lookups unless overridden by apps) and then try again. After a few SRV failures, the OS would revert to an A record request. But by then most users had either cancelled the request or fallen asleep. #

The “fix” was that Apple reverted the DNS lookup behavior in 10.5.3 to way lookups were done in 10.4 and earlier - via “A” records.

The solution for me was to edit the .htaccess file in the root directory of my webserver (the directory where Wordpress is installed). Add the following to the the .htaccess file after the “END WordPress”:

<IfModule mod_security.c>
<Files async-upload.php>
SecFilterEngine Off
SecFilterScanPOST Off
</Files>
</IfModule>

If you are having the problem of your .htaccess file losing its changes, you have most likely put something inside the Wordpress block of the .htaccess file. Keep any custom changes outside of that block or they will be overwritten.

Intuit claims that the problem that caused deletion of some users’ Desktop folder has been fixed (via their community forums). Proceed with caution (ie. backup your important files).

If you are a user of QuickBooks for Mac, beware that there is a problem with the latest update for QuickBooks 2006 and 2007. The updater is showing a “not enough free space” message (regardless if enough free space actually exists - and keep in mind, this appears to be a 100K update), if the user then clicks “OK” - the result is that any documents, files or folders that were stored on the desktop are then deleted - and as of right now, no simple recovery method appears to exist.

For now, it is recommended to turn off QuickBooks’ automatic updates. This can be done one of two ways.

Type in terminal:

defaults write com.intuit.QuickBooks2006 QBCheckForUpdatesKey NO

substitute 2006 for 2007 if necessary.

Then hit Return
Then Quit Terminal

OR

Open the file com.intuit.QuickBooks2006.plist in Users/~your user/Library/Preferences and with Property Editor set the flag for QBCheckForUpdatesKey to Boolean “No”
save and quit Property Editor. (again, substitute 2006 for 2007 if necessary)

FileMaker, Inc has a note on their site recommending that FileMaker 9 users not upgrade to Leopard yet. Compatibility updates are currently being worked on.

We are very excited about the release of Leopard (Mac OS X 10.5). We are currently working on Leopard compatibility updates for FileMaker Pro 9, FileMaker Pro 9 Advanced, FileMaker Server 9 and FileMaker Server 9 Advanced. At this time FileMaker does not recommend the use of FileMaker 9 products on computers running Mac OS X Leopard.

If you would like to be notified when these updates become available, please subscribe to FileMaker News.

We also do not recommend the use of earlier versions of FileMaker software on Mac OS X Leopard as we have not performed compatibility testing.

Update: FileMaker has revealed the known issues:

• The Instant Web Publishing feature does not work.
• On Leopard (Mac OS X 10.5), each language version of FileMaker Pro 9 and FileMaker Pro 9 Advanced works only when the Mac OS System Preference “International Formats Region” is set to a specific region. For example, the English language version of FileMaker works only when the region is United States. It does not work when the region is United Kingdom, or Australia, or France, or any other region.
