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]
Type an em-dash on an iPhone
Typography and punctuation geeks rejoice! It's easy to type an em-dash on the iPhone's or iPod touch's virtual keyboard. To do so, tap the .?123 key to switch to the numeric keypad. Then touch and hold on the Hyphen key to reveal a pop-up strip showing an em-dash. Slide to the em-dash and release your finger.
Note that this basic trick works with many other keys on the virtual keyboard.
