So I recently upgraded my PBG4 1Ghz TiBook from 10.3 to 10.5, and I've had a bunch of problems crop up. 1. Network issues. As part of the upgrade, my Airport Extreme and Airport Express were updated too. Now Airport Utility doesn't see my AEBS or my AEX half the time (or will see one but not the other) unless I plug in using the ethernet port. Also, signal strength seems to have degraded considerably. I'm typing this with about 6 feet between my computer and my base station, and I only have three of four bars. At my couch, I used to receive four bars, but now only two. Previously, I was able to roam my house without dropping below the full four in any location. 2. Embedded videos. Gone. Can no longer see video streams on news sites, youtube videos embedded in web pages, and the like. 3. iPhoto. Dead. Do I need to purchase iLife separately? I thought this was included with previous versions of OS X? 4. Laptop speakers. Dead. iTunes plays music, but only the occasional crackle emerges from the speakers. 5. Time Machine. Doesn't work with my external HD. Other than that, I like 10.5 so far. But unless I can solve at least the first four problems, I'm going to have to uninstall it pretty soon. Thus, any suggestions would be greatly appreciated.
