Hi. First my specs: Mac Pro 2x2.66Ghz, Nvidia 7600 gfx card, 3 GB RAM, four internal harddrives. I wrote some time ago about some OS X GUI screwups. I thought they were gone with the latest updates, but they are not. 1. When starting programs, they don't always come to front by themselves. 2. (This is the most alarming to me): Sometimes the OS seems to lose focus on which program it is in, and menus stop working properly. Let's say I am in Safari. If I click the "Safari" roll-down menu, it opens, but when I move the mouse down the different sub-menus, they don't get highlighted. If I click on a sub-menu, it is activated though. Also if I click "Safari" and move the mouse through the other main menus, they are not highlighted, until I click them. And getting into sub-sub-menus is impossible during this behaviour, which only goes away when I reboot. It doesn't happen often, but then again, I have hardly begun using my Mac for anything serious, so I fear that when I really start using the resources and such, it will happen a lot, which will be a PITA... 3. I can't update to the latest EFI update. When I follow the instructions, the progress indicator just comes on for a split second, then the machine reboots, without having done the update. Yes, I have disconnected alle FW and USB devices, doesn't help. Do you think Apple will have a clue if I call them and explain these problems to them? And will it cost me to get this support, now the 90 day period of free support is over, even though it COULD be a hardware malfunction in their product? For sure I know it isn't a fault on my end. I tried re-installing the OS from scratch and I still get this behaviour. Hmm... it's pretty disheartening that a piece of expensive and so-called user friendly equipment behaves in this erratic way. Any clues? Thanks.
