Turn Off Filename Extension Warning

In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.

Avoid AKUA Interactive's Nine 11 Utility! AKUA Interactive Media has released an extension called Nine 11 that prevents Mac OS 9 from stopping certain incompatible programs with error number 119. To quote MWJ publisher and TidBITS contributor Matt Deatherage, this is "an indescribably irresponsible idea roughly on par with disconnecting the buzzers in your smoke detectors." As we explained in "Mac OS 9 Installation & Compatibility" in TidBITS-503, to increase the maximum number of open file forks in Mac OS 9, Apple had to change the file control block (FCB) table that the Mac OS uses to track open files. Even with all their resources, there was no way Apple could maintain compatibility with old code that ignored Apple's recommendations and accessed the FCBs directly. So Mac OS 9 prevents programs from doing that, because code that goes directly to the FCBs would likely crash the system or corrupt data on your hard disk. Why is this? Applications accessing the FCBs probably want to read data about which files are open, but because of the changes in Mac OS 9, those applications will read the wrong data. If that application then uses that incorrect information as input for other disk-related functions, disk corruption is likely. In short, if you see this utility online, do not download it and warn anyone using it that they do so at significant risk. [ACE]
