MacOS 10.4-compatible programs really are a dying breed. First, VLC stopped supporting 10.4 in new versions (last 10.4-compatible version is release 0.9.10), then Eclipse stopped supporting 10.4, and now VirtualBox has dropped support for 10.4 as well (last 10.4-compatible version is 3.0.12). I guess it’s high time for a new MacBook (Pro), but I want to wait for the next update.
You may ask why I don’t just install MacOS 10.5 or 10.6. As I explained before, because Apple doesn’t support Java 6 on 32-bit Macs. I have a first-generation Intel MacBook (Core Duo, not Core 2 Duo), and I need Java 6.
