iMac Wi-Fi Update 1.0 -- Apple has released the iMac Wi-Fi Update 1.0, which is recommended for all iMacs released since late 2009 that are running Mac OS X 10.7.3. The update resolves an issue that can prevent an iMac from automatically connecting to a known Wi-Fi network after waking from sleep. It’s available for direct download, but it’s easier to get through Software Update, where it will appear only if it’s necessary for your iMac. (Free, 25.81 MB)

Firmware Updates for iMac, Mac mini, MacBook Air, and MacBook Pro -- Apple has released a quartet of firmware updates for models released in 2011: iMac EFI Firmware Update 1.9, Mac mini EFI Firmware Update 1.6, MacBook Air EFI Firmware Update 2.4, and MacBook Pro EFI Firmware Update 2.7. Each update improves reliability when booting from the network, addresses issues with HDCP authentication after rebooting, and fixes a problem with boot device selection when a USB storage device is hot-plugged. As with any firmware update, you should read the installation instructions carefully before installing and avoid interrupting the update process. To ensure you get an update only if it’s necessary, we recommend relying on Software Update; if an update doesn’t appear for you, it’s not appropriate for your Mac. (Free, each approximately 4 MB)

PDFpen and PDFpenPro 5.7.2 -- Preparing for the release of OS X 10.8 Mountain Lion, Smile has released PDFpen 5.7.1 and PDFpenPro 5.7.1, both of which are updated with the Smile developer ID that is used by Mountain Lion’s Gatekeeper security feature (see “Gatekeeper Slams the Door on Mac Malware Epidemics,” 16 February 2012). The updates to the PDF manipulation tools also fix a gradual shift in color when using comments and an issue with the text tool when object stroke is set to none. A quick 5.7.2 release fixes a potential issue with saving, primarily on 10.6 Snow Leopard, and another issue with localization of page numbering.
