Useful Fruit Software has released Pear Note 3.1 with full support for Retina displays on Macs. The multimedia note-taking app adds support for using images (like photos of slides in a lecture!) in the just-updated Pear Note for iOS 2.1, and it now saves documents in an updated format that can be read by the iOS app. For older Pear Note documents that include images, Useful Fruit suggests opening and re-saving them so they work properly with the iOS app. The release also fixes a bug with saving that caused slides to move back, an issue where shared documents with special characters displayed improperly when hosted on Dropbox, and bugs associated with Spotlight results and the Quick Look generator. Finally, the Mac App Store version is now sandboxed. ($39.99 new, free update, 4.6 MB, release notes)
Improve Apple Services with AirPort Base Stations
You can make iChat file transfers, iDisk, and Back to My Mac work better by turning on a setting with Apple AirPort base stations released starting in 2003. Launch AirPort Utility, select your base station, click Manual Setup, choose the Internet view, and click the NAT tab. Check the Enable NAT Port Mapping Protocol (NAT-PMP) box, and click Update. NAT-PMP lets your Mac OS X computer give Apple information to connect back into a network that's otherwise unreachable from the rest of the Internet. This speeds updates and makes connections work better for services run by Apple.
