Apple has released iMac SMC Firmware Update 1.1, which is recommended for recently released iMac models that have been configured with PCIe-based flash storage (see “Apple Updates iMac with Faster CPUs and 802.11ac Wi-Fi,” 24 September 2013). The release improves the Power Nap feature in OS X 10.9 Mavericks so that it runs silently while your iMac is sleeping without spinning the fan. (Free update, 921 KB)

You can make text bigger in Excel by zooming to a larger percentage with the Zoom control in the toolbar, or by selecting the cells containing too-small text, choosing Format > Cells (Command-1), and then setting options in the Font pane. You can also increase the default font size for new sheets by modifying the Size field (next to the Standard Font field) in the General pane of Excel's preferences.
