I talk to Cisco gear a lot -- our security system includes a score or so of PIXen and ASAs -- and their Java-based GUI doesn't render worth a damn on my Mac. Unfortunately, it makes my MacBook a little annoying as a carrying tool, such that I put a Win VM (under Fusion) on for the express purpose of dealing with the Cisco GUI.
Granted, I do most of my config work in IOS (PIX-OS, whatever) over the serial console. But there are times when the GUI is a nice display -- and yet it's damn near worthless on the Apple, while it displays just fine in Windows.
Part of it is the menu -- there are whole pieces missing, some of which are critical. But the geometry of the dialogs is screwed too, and repaint is stupid and incomplete a lot of the time.
I'm guessing this is at least partly the fault of the Apple Java. I wish I could get a Java update other than from Apple to test it out and see what's up.
That's about the worst complaint I have after switching from a Windows notebook to a MacBook. Not bad, overall...
