"Apple has seeded Mac OS X 10.4.7 to Apple developers earlier this week. The current build is reported to be 8J111 for PowerPC and 8J2111 for Intel Macs. Areas of testing are listed as Mail, Safari, Aperture, Syncing and iChat. Known issues include inaccurate Calculator results and Mail signatures note working reliably." Inaccurate Calculator results?! its about time they figured out this maths thing really... Should be about a month or so I rekon. 10.4.8 by August, 10.4.9 by end October and 10.5 by Christmas or Jan 07... according to my iCrystal Ball.
