Hello everybody! I've upgraded to Lion and am mostly enjoying the new OS. However, a problem that I've found quite prevalent has been input lag. It's not happening as I type this, but sometimes when I type something it'll take several seconds for it to come up, with the computer slowly bringing up each letter. It's never done this before, and processor usage doesn't go up when it happens. I also had a problem not too long ago where the keyboard stopped inputting text. I could still use it to switch Spaces and show desktop and such, but it couldn't be used to type into any app. Unplugging and replugging didn't fix, and I ended up having to restart. Is anybody else having these issues? And if so, has anyone found a fix?

iMac, Mac OS X (10.7), 17" 1.83 GHz Core 2, 2GB RAM

    I was disappointed to see that there was no response to this post. I have three macs: a Mac pro, a 2009 MB Pro, and a new Mac mini. The first two machines were upgraded from snow leopard and they are experiencing the same keyboard lag issue. Characters are often transposed, especially in situations where there is a pause in typing. It doesnt look like bluetooth is the problem, because the lag occurs with the MacBook Pro's built-in keyboard too. The problem doesn't seem to exist on the native Lion Mac Mini. How can I resolve this on my other two macs? This is insufferable.

    Open Activity Monitor and look for processes using CPU while this is going on. Is this when using certain apps? Is it in large documents or ones containing embedded items? We need more information!

    Seems to be most pervasive while in Outlook Mac 2011 (where I spend most of my time -- mainly just emails, nothing overly complex), but I've seen similar behavior with other apps too (Excel, Safari). I've done permissions repairs, re-paired the keyboards, repaired my Outlook database, and created a new identity for myself in Outlook all to no avail. I'll check activity monitor later and see if there are any clues there. Thanks for the suggestion.

    Checking Activity Monitor now. There are a lot of processes active, but none taking more than a small percentage of total CPU (Outlook as at roughly 15%, everything else at 0.5 or less).

    I've seen a similar problem on my wife's three year old MacBook Pro (4 GB memory installed).  Repairing permissions doesn't seem to help and no obvious other things going on in the computer.  Most often seen in Mail but that may be because that's what gets used the most.

    I think I've discovered the problem:  I use TextExpander and it is doing some key logging that is causing the delay in inputting.  Shutting down TextExpander solves the problem (though it obviously makes TE useless). I'm working with their support team on resolving the issue permanently.

    I have a similar issue. I experience lag when typing, and the letters sometimes come out in the wrong order.

     

    How can I be sure I didn't type them in the wrong order? Because, sometimes, the first letter of a word appears after several others. I might make mistakes, but not on the first letter, at least, not when I noticed it's happening and tried a few times.

     

    It's not consistent, but it is happening to me intermittently on 2 different Macs I use.

     

    I use TextExpander, too, and I love it. I wondered if TE were causing the prob, and I've tried typing a while without TE enabled. It doesn't happen often enough for me to easily  troubleshoot this, but it happens every day lately for the past few months, if not longer.

     

    I thought the lag might be caused by Mac OS X, too, because I set a LOT of custom keyboard shortcuts. Because I do that, I expect that the OS is also doing extra special keystroke-logging (keystroke-detecting?) that adds to the overall CPU workload.

     

    Just not sure.

    I'm seeing this too. Thought I had it nailed, but it re-appeared in 10.7.3. It does seem to be TextExpander related: As williambsmithjr reported, quitting TextExpander stops the problem; however if i Re-start TE, the problem does not re-appear. This suggests it may be an interaction with another startup item. It appeash you can change the startup order by dragging login items around, so I'm going to try dragging TE to the last item.

     

    My symptoms seem to appear worse if

     

    • I have the caps key pressed at the beginning of a line
    • I have just switched into an application

     

    Anyone else see this?

    I'm glad that I found this topic - I have the same problem for about two months.

     

    It's often occurring directly after I boot up my computer. I'll now investigate what causes this and post my findings here.

     

    A temporary fix for is always: to log out and log back in again. Then I'm spared with this behaviour for at least 6 hours. Often in the evening it begins to lag again.

     

    Hope we can find a solution to this. I have quiet a few applications in my startup queue, for now I'll keep my eye on TextExpander since it's mentioned here.

    Slow behavior of Lion when upgrading from SL is usually due to older apps starting up at login. If you have such apps/utils, uncheck them, let only Apple apps to that.

    What else do you have installed. Is this slow behavior usual, immediatley after logging in or some time later? Do you notice any relation between lag and a certain app?

    Otherwise:

    - run disk utility and repair permissions, then restart

    - immediately after initial chime, press shift key, this will start a safe mode start, which is a lot longer, let it finish; it is ok if you start in this way?

    If yes, as I assume, restart normally as look for old, obsolete app incompatible with Lion, you must have some.

    Speaking for myself, I find myself faced with the issue on startup or after a certain time (see the previous post).

     

    This is my startup list - all applications claim to be Lion compatible:

     

    • FontExplorerX
    • QuickCal
    • Growl
    • PhotoSync
    • Alarms
    • LaunchBar
    • TextExpander (none MAS version)
    • Transmit
    • Quiet Read
    • LittleSnapper
    • Cloud
    • MsgFiler
    • HyperDock
    • PTHPasteboard
    • MenuEverywhere
    • BetterTouchTool
    • Flux
    • Pastebot
    • Yoink

    You mean ALL these apps are set to start up at login??!! It is not only about claiming they are compatible, it is about their being TOO MANY at a time. How much RAM  do you have? 1 TB?

    Uncheck 95 % of them, let 3 of them, and start them if need be. do not tell me you need all of them all the time?

    I'm a power user - trust me, I need them. Of course I don't need Little Snapper all the time, but most of these apps are designed to be background apps (Hazel, Keyboard Maestro, GeekTool, Default Folder, etc.) - they only work on the basis that they run all the time. On the other hand there's no point in starting up apps like DropCopy or Pochade only when I need them (which is at least one 5 times a day).

     

    I've no RAM problems here (10 GB) and no CPU problems, but I've just started diagnosting this issue. The standard tricks like "repairing permissions" or "resetting the PRAM" doesn't work here. I post it if I find something that's worth mentioning. I'll turn off some apps for one day and see if I can narrow it down this way - tomorrow for example will be a day without TotalFinder.

    I have the exact same issue and sadly it seems to me to be a problem with Text Expander.  I have switched it off and the problem goes away.  One can achieve a certain ampount of TE's utility using the built-in Lion spell checker but it is nowhere near as good

     

    After I installed Lion my iMac started crawling but I found (in Activity Monitor) that my APC Powerchute software was using 97% CPU power!  Once I stopped that app running at start-up Lion started working OK.  I hope TE comes out with a fix as I miss it hugely.
