Rewind Advances to 1.2 -- Power On Software has updated Rewind, its $100 utility for reverting to previous incarnations of files or the system in the event of a crash or mistake (see "Macworld SF 2001 Trend: Cool Utilities" in TidBITS-564). Rewind 1.2 adds the capability to limit the size of the Rewind archive (the catalog of changes made to files as you work on the Mac), improves stability with programs that handle memory in unusual ways, and now correctly handles Virtual PC 4 disk images, among other fixes. Although the upgrade is free, you must enter your serial number to download the full version of Rewind 1.2, including manual (a 7 MB file). Rewind runs under Mac OS versions 8.1 to 9.1 and requires at least 10 percent of your hard disk space to operate. [JLC]
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.
