Little Diva Fan Level 1 Level 1
Since I upgraded to Snow Leopard, my intel Imac takes a very long time after booting to respond to a key stroke or a mouse click. The OS launches, everything is there, and the mouse can move the cursor, but invariably it takes 4 minutes before any programme can be launched, or menu dropdown invoked, or mouse click can invoke any action. Have tried with both bluetooth logitech mouse and apple usb mouse. Same response. Any suggestions? Thanks.

IMac, Mac OS X (10.6)

    Once or twice just after my SL upgrade I had to unplug and replug my keyboard/mouse USB connector to make them recognized again. After the second reboot and replug I've not been plagued by that issue again.

    I've tried that several times, but it hasn't yet made a difference. Were you getting that 4 minute delay startup and then working normally?
  • Welles Goodrich Level 4 Level 4
    No, I never waited. Over the years of using lots of different Macs I just have an automatic reaction... when the mouse/keyboard isn't active upon start-up I just unplug the USB connector and reconnect and they almost always work. I can't remember when that failed. As it doesn't work in your case you must have a different problem. Sorry, I'm afraid I don't have any further guess or suggestion.

    I have the same problem. If you set my iMac to automatically login, it gets to the desktop and does exactly as described above. If you set it so that you have to log in, then it waits at a blue screen for 4-5mins and then the login screen pops up.

    I think this problem with the keyboard and mouse not working is the same reason that my iMac is not waking from sleep either. It's almost like the keyboard has a little sleep and then decides to wake up and work in a while.

    This is all using a USB powered aluminium keyboard.

    I am really holding off installing SL on my Macbook until these issues are solved.

    This happens to me on my MBP as well... Not sure why I upgraded?

    I'm having the same problem after I upgraded Snow Leopard, on my MacBook.

    This happens even in safe-boot.

    On top of that I notice there is a small lag in videos, mouse, keyboard and basically entire interface functions—AFTER the 4+ minute of no mouse or keyboard downtime.

    Same Problem here. My upgrade to Snow Leopard failed, so I made a clean reinstall of Snow Leopard and then let it update to 10.6.1. Now when booting, the white boot screen with the rotating icon stays for several minutes, and when the desktop finally appears, the system is unresponsive to keyboard presses and mouse clicks for a very long time. The entire boot process takes 10-15 minutes until the machine is fully booted and responsive. I'm already thinking about going back to 10.5.8, where booting was much much faster.

    I wonder I this happens to all late 2008 13" Macbooks, or if there is something broken about my machine. This is a clean install of Snow Leopard with no additional software installed except Boot Camp, so maybe it has something to do with that?

    Same thing still happens in 10.6.2: no keyboard or mouse click response for 4 minutes after boot.
    I even reinstalled Snow Leopard from scratch and updated to 10.6.2: same story.

    Does anyone else have this problem, and is there a solution for this?

    Just wondering if anything was solved with this issue. I just installed a fresh copy of Snow Leopard on a new hard drive, then upgraded to 10.6.2. Everything seemed to be working fine then suddenly one time when I woke the computer from sleep no mouse activity and no cursor. So I pressed the keyboard to see if I could move around the desktop and no response from any key. Couldn't log out. Unplugging mouse didn't work nor did unplugging keyboard.

    Anyone know what else to do?

    Since this is an old thread I'll just mention that some of these kinds of hardware issues can be fixed by Zapping The Pram: http://support.apple.com/kb/HT1379 - especially when reinstalling the OS does not fix an issue.

    There are many settings stored on the Logic Board's Pram chip and they can become corrupt or have incorrect settings.

    Worth a shot, and free.
