Avoid Current Firmware Updates -- Apple's just-released firmware updates (4.1.7 and 4.1.8) for recent iMacs, plus the iBook, G4 Cube, Power Mac G4, and PowerBooks with FireWire ports have caused much gnashing of teeth. The firmware updates, which were released both on the Internet and on the Mac OS 9.1 CD-ROMs that come with Mac OS X, claim to make improvements to FireWire target disk mode, network booting, gigabit Ethernet networking, and overall stability. They also enable password protection of Open Firmware booting to increase the security of Mac OS X (which can protect its files via user privileges, but can't do so when booted from Mac OS 9). The significant problem with these firmware updates is that something in them can prevent the Mac from recognizing some RAM modules from third party vendors. Apple has yet to make an official statement about the situation. Our advice: don't install these firmware updates until there's word from Apple. [ACE]
Enabling Auto Spelling Correction in Snow Leopard
In Snow Leopard, the automatic spelling correction in applications is not usually activated by default. To turn it on, make sure the cursor's insertion point is somewhere where text can be entered, and either choose Edit > Spelling and Grammar > Correct Spelling Automatically or, if the Edit menu's submenu doesn't have what you need, Control-click where you're typing and choose Spelling and Grammar > Correct Spelling Automatically from the contextual menu that appears. The latter approach is particularly likely to be necessary in Safari and other WebKit-based applications, like Mailplane.
