Apple have definitely gone Vista with Leopard. 10.5.2 continues to be plagued with bugs both new and unresolved from 10.5 and 10.5.1

The best is that the 10.5.2 installation completely bricked my Intel Mac mini. Can't even boot it - it just restarts every minute or so while on the initial grey spinner boot screen.

Installation on my PowerBook first wouldn't go because of permissions issues (caused by previous versions). Once that was fixed update went off without any reported errors. Restart showed 10.5.1 was still running. No sight of 10.5.2. However some prefs, including third-party enabler for two-finger scrolling had been disabled along with Safari plugin Stand.

In the morning I'll do a new complete backup of this system before trying to apply the combo updater I just downloaded.
