I have a macbook core duo. After 10.5.2 update, there are some problems. 1. the battery meter does not work accurately any more, when battery goes down to about 20 min, it will increase back to 1 hour, then after 20 min the computer will suddenly shut down, without any warning. 2. powerpoint 08 takes forever to start up, and print. 3. time machine seems to take a long time to prepare. 4. flip4mac in safari seems strange, the NBA.com video is not displaying at the right ratio. other things in general, >wireless works fine, just as before, (I have an airport express) >printing via airport express linked wireless printer is fine, just as before >graphics seems to be improved >the Mail.app is a new version, maybe also iCal.
