Mouse Not Antialiased After Wake from Sleep? (on external display)

I've been noticing something very strange lately: after waking the MacBook Pro from sleep, the mouse on the screen is no longer antialiased and is instead quite rough looking — it also has no shadow. I've only noticed this when using an external display. If I'm using the MacBook's built-in screen instead this doesn't happen. Not really a huge problem but I was wondering if anybody else had this issue and if there's a fix. Thanks.

I'm sorry, what? Forgive me if I say that your reply doesn't make any sense. This issue almost certainly has nothing to do with the hard drive failing (or being too stressed), nor is it a lack of RAM. In fact, given that it's only with the external display (Apple LED display), it really almost certainly has nothing to do with the hardware it all. Without a doubt, it would appear, it is a software bug of some kind. For example, if I log out and log back in again, it's fine. So, a minor annoyance, but I'm curious if anyone knows about it/knows of a fix.
For the record, I haven't "bell/whistle"d the Finder at all. I don't see how that's relevant in any way, anyway.
I personally speculate this is some sort of bug with Mac OS X; I was wondering if anyone else had had a similar issue.

  • WiFi not found after wake from sleep

    I have my home wireless network set NOT to broadcast. This should pose no problem once I save it as a trusted wireless network. When I start up my computer and log in, it connects to my home network automatically without any trouble. However, when I wake from sleep it frequently says, none of your trusted wireless networks could be found and I either have to connect manually (by entering the SSID and password) or cycle my airport power off and on 2 or 3 times until it realizes the network is in fact there. The signal strength is very strong (I'm only about 10' away from my router), so that's not the issue. I've seen other macs have the same issue. Has anyone else experienced this or found a solution. It seems like it is giving up on its search of trusted networks before the airport has fully powered on or something. Maybe there's a setting to tell it to rescan a few times before giving up? It's very frustrating.

    I finally had the problem once while trying to connect manually. It kept saying connection time out before finally connecting. How does one increase the connection timeout time?

  • Canon LiDE 100 does not respond after wake from sleep

    I have a Canon LiDE 100 flatbed scanner. I constantly put my iMac to sleep and only ever shut it down once every few weeks.
    When the computer wakes from sleep the scanner does not respond. Image Capture lists the scanner in the device list but reports the following error;
    "An error occurred whilst communicating with the scanner"
    I have to unplug the USB cable and plug it back in for it to work (or restart the computer, both always work).
    Since I only moved to the Macintosh in July I have no idea how to uninstall drivers to give myself a fresh start and the scanner does not come with an uninstall utility.
    Any suggestions on how to fix this little problem?
    Thanks.

    I am going to respond to my self and say I am nuts.
    Canon does not seem to have any uninstaller for this scanner on their site:
    http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=DownloadDet ailTabAct&fcategoryid=351&modelid=17104
    Which is rather odd since they have installers. this is different from most of their other older scanners. But if you just plugged in our scanner and things worked in OSX, which it should have, then you should be OK.
    However I can confirm that others see this issue (like my dad) and here is the official Canon response to the issue:

    Of course this in not exactly true as logging out and back in fixes it.

  • Firefox 15 UI does not update after wake from sleep

    On my Netbook running Windows XP 32-bit, if I leave Firefox open when I put the computer to sleep (by closing its lid), then when I wake it up from sleep, the user interface elements (like the tab bar) won't respond to mouse clicks. This does not happen 100% of the time; in particular it won't happen for a freshly restarted Firefox that is put to sleep, making the problem rather annoying to reproduce. As far as I can tell, I might have to visit some set of websites with Javascript or Flash or something.
    Here are some more details about the user interface, because it is not as simple as non-responsiveness. When I wake it up, when I click on a tab to switch to it, the Windows title bar actually changes to display that tab's page title, but nothing else in the UI updates including the URL bar and the actual page displayed. Similarly for closing a tab; the tab remains, but the title bar shows the title of the tab that would receive focus next. After I "pseudo" close a tab and then restart Firefox, it does not remember that I closed the tab (I save sessions) and restarts with the same set of tabs before I tried to close one.
    I get the problem even after disabling all extensions and resetting all toolbars to defaults. I have not tried to create a new profile because I have a lot invested in my current profile.

    I am going to respond to my self and say I am nuts.

  • USB devices not working after wake from sleep on WinXP!!! HELP PLEASE!

    I would like to put my windows xp to sleep whenever I leave the macbook pro for fear of overheating too much when I'm not using it.
    The only problem is that I can't use any more USB devices if I plug them in once I wake it from sleep.
    Like my mouse for example, I'm using a laser mouse with a usb plugin but it doesn't respond once I try to use it after WinXP on wake....
    Experiencing a ton of wake problems lately...
    Sleep is important for a MBP....I hope...

    Welcome to Windows. Some devices do not like to be put to sleep in Windows.
    There could be driver updates or hot fixes from MS to fix these.
    A very proven method (though not for battery life) is to instruct the devices not to go to sleep when the system goes to sleep. You can do this via the device manager in the control panel.
    Its not a gracious solution but it will do what you want it to do.

  • External keyboard and mouse not recognized after waking from sleep

    This started happening all of a sudden. It was working fine before that. When I disconnect the power cable, keyboard, and then connect them back, its not recognized. To make it recognize the keyboard and mouse, I have to logout and login or restart the laptop. I looked at this related post, but the PRAM reset fix did not work for me : http://forums.macrumors.com/showthread.php?t=870482
    Any idea how to fix it?
    OS version: 10.9.2
    MacBook Pro 13-inch Mid 2012
    Processor 2.9 GHz Intrel Core i7
    Memory 16GB 1600 MHz DDR3

    I have a similar problem on our G3 iBook with Panther. Most of the keys don't work, and of the four or five that do, they print only gibberish.
    For a while I had control of the "C" key, and I was able to start from the Installation CD-ROM. I ran Disk Utility. It found and repaired a whole bunch of permissions and reported no problem with the hard disk. But I still cannot use the keys, and since then I've lost the use of the "C" also.
    Because I cannot use the keyboard, I cannot type in my administrator's password, and for that reason I cannot use System Preferences to start from the Installation CD-ROM. I did not see the Hardware Test on the CD-ROM, but it sounds interesting.
    Any ideas on how to get back to the CD-ROM when my keyboard doesn't work?

  • USB mouse freezes after wake from sleep.

    Since the 10.8.2 update my Logitech USB mouse freezes after waking up the computer from sleep or when it goes into energy save from non use. This also happens to my brand new MBPR. I tries repair permissions and reset the smc. Any suggestions?

    I get a frozen mouse (Microsoft Intellimouse Optical) on my 2012 Mac Mini running Mavericks (it did it with Mountain Lion also) when waking from sleep about 75% of the time which works again if I unplug/replug it (light is on and mouse buttons work when it's frozen, but the pointer won't move).  It does this whether I use a built-in USB3 port, a USB2 hub and now also with my new USB3 hub. 
    However, my 2008 Macbook Pro also has an Intellimouse connected to it when docked and it NEVER freezes when waking from sleep whether using the built-in USB2 port or a Gmyle USB3 card port.  Either way, the mouse wakes fine and it's the SAME MODEL MOUSE and SAME OSX verison.  I have no idea why the inconsistency.  It ***** because "Wake on Network Activity" FINALLY works right here in Mavericks with XBMC on my Mac Mini so there's a perfect opportunity to save some electricity.  I got excited when it woke up two times in a row with 10.9.1 and set up my sleep controls only to find it wouldn't go to sleep with the Energy Savings menu because I have an external USB3.0 3TB media drive connected (at all times).  I finally found out (through more patient testing) that once the drive spun down (possibly on its own power saving timer as I'm not sure the "Shut down hard drives when possible" setting works in Mavericks; it was messed up in Mountain Lion in 10.8.4 and even though 10.8.5 fixed it, I'm not sure Mavericks is using the same code.  It doesn't seem to shut down any faster with or without the setting on and shuts off several minutes after the computer attempts to go to sleep (on a 1 minute test setting; I think WD defaults to 10 minutes in firmware). 
    Anyway, once that was resolved and I saw it would go to sleep eventually once the drive spun down (it will sleep instantly if I select SLEEP from the Apple menu which I find odd if it's such a big deal that it's connected....), I thought OH BOY!  I'm all set.  Then I woke it from that sleep and found my mouse was frozen again..... :-(  What a PITA to unplug/plug the mouse every time it wakes from sleep.  It's not worth it.  I'll just have to pay the extra few bucks in electricity each month I could have saved to avoid such a freaking nightmare hassle.  Why on God's Green Earth, Apple CANNOT or WILL NOT fix their darn energy savings features is just beyond me.  Instead of spending all their time making horrible horrible ugly icon/GUI updates to iOS and making it slower and slower and slower, why don't they actually fix some darn bugs in OSX for once in their lives.... I'm starting to think I should give Windows another chance I'm so annoyed right now.  But then I think about having to run a malware program and have that program update and Windows software/security updates 3x a day and I think I can just deal with the Mini not sleeping.....
    I'd like to know why Apple couldn't figure out those of us with multiple monitors would want a dock on BOTH monitors all the time either (first side-mount docks wouldn't migrate and now in 10.9.1, bottom-mounted docks won't migrate here either, leaving a dock on one monitor all the time and if that's the monitor that is showing full-screen video, you lost your dock completely while the video is playing.  They finally figured out after a full decade that having a menu bar on both screens would be a good idea, but it just didn't occur to them that the same is true of the dock.  How much are they paying these guys?  Too much apparently (or is it too little to attract talented thinkers? Nah, it couldn't be since we give them feedback and they just ignore it).

  • External monitor flashes on and off randomly after wake from sleep

    I have a Mid-2009 13" MacBook Pro 2.26GHz hooked up to a Samsung SyncMaster 2033 External monitor via the MiniDisplayPort-DVI connector.
    After waking from sleep, the external monitor will go blank for a fraction of a second at random intervals (display on the MBP remains normal). The flickering clusters are about minutes apart, while flickers within a cluster (usually 2-3 flickers per cluster) is of order seconds apart. "Detect displays" will not make this go away. The only way I can make it go back to normal is to unplug-and re-plug the MiniDisplayPort connector on the MBP.
    Anyone else got a more elegant solution to this that does not involved wearing down the displayport?

    I tried this.  No change.  However, I did start playing with the Display settings.  Oddly enough, when I change the disfunctioning monitor to 720p it starts working again.  Does this mean anything to anyone? 

  • BUG: Sandisk USB flash drive in "half-mounted" state after wake from sleep

    My Sandisk Cruzer Crossfire 4GB Flash Drive is left in a half-mounted state after wake from sleep. The Finder believes the drive is still mounted, the icon is on the Desktop. However opening a file on the drive, or trying to eject the drive, results in a long beach ball, followed by a message that I removed the drive without Ejecting it first. The same drive continues to work fine on my Tiger machine, and on PCs.
    Bug Report:
    Setup:
    Macbook 1st Gen (2.0 Ghz)
    Mac OS X Leopard 10.5 Clean Install
    Sandisk Cruzer Crossfire 4GB USB Flash Drive (in either port)
    Repro:
    Plug in the drive.
    Close the MacBook to put it to sleep
    Reopen the MacBook
    Result:
    The lights on the flash drive never light back up after wake from sleep. Navigating the drive, or trying to eject it results in a "you removed the device without ejecting it first" message.
    Expected:
    Drive should still be mounted and accessible after waking back up.

    It may be a design flaw in the device. Mac OS X does a lot more power management than most other OSes, including tearing devices down to little or no power during sleep. It is possible that the device simply misbehaves due to corrupted memory state or reports a substantially different GUID or something similarly bizarre upon wake. (Okay, that last one wouldn't technically be a power management issue....)
    If it doesn't have any problems except when sleeping the system, I would just make sure I unmounted it before putting the machine to sleep and wouldn't worry about it. Maybe check with Sandisk to see if they have a firmware updater for the device.

  • Left USB-Port dead after wake from sleep. Just restart helps.

    I hoped Apples keyboard-Update today would solve my biggest hate-bug in this buggy POS called Leopard. It didn't.
    As usual on my Leopard-Macbook Pro, no device will work on the left USB-Port after I waked the computer from sleep. Just a restart helps. I hoped this update to solve this, because it replaced among others "IOUSBFamily.kext".
    Terminal gives a timeout error for the internal USB-Hub after wake from sleep. I assumed this should be related.
    I'm really angry now.
    When will Apple solve the most urgent problems in Leopard?
    Was 10.5.1 just smoke and mirrors to make (fool people into...) people upgrade who intended to wait until the first maintenance-update?
    Was Leopard Apples attempt to make Windows-Users more comfortable by putting in some heavy extra-bugs and blue screens?
    FIX IT FINALLY! And f... don't wait for Macworld to release 10.5.2. It's desperately needed and the current state of Leopard will leave some people very sad at christmas after getting their first Mac. First impression counts and many more peoples first contact with the Mac will be at christmas...

    Apple knows the problem and for some reason they are stumped on fixing it. this is so bad I can't believe it. On my macbook pro with Leopard installed, USB left port is dead after sleep. Only restarting can power it back up. I have to restart every day to use my external hard drive for time machine or when putting my flash drive in the port.
    Come on already Apple. This is a SERIOUS, SERIOUS problem.
    Fix it.

  • Password not required immediately after wake from sleep

    Every once in a while when my retina macbook pro wakes from sleep I do no need to enter my password immediately.  Instead it just starts with no password required and then 5-10 seconds later it takes me to the lock screen and asks for my password.  Other times it will ask for my password, start up after its entered and then 5-10 seconds later it takes me back to the lock screen and asks for my password again.  Usually when it "takes me back to the login screen" it actually just makes the screen black until I press a key or move the mouse and then it "wakes up" again and shows the login screen.
    Also is it common for it to hang for a while before allowing me to type my password after waking from sleep?  Frequently it will take 10+ seconds before I can start typing in the password field or the clock updates etc.  Its a 2.3ghz core i7 with 16GB of ram.
    I have installed all updates and it should be noted that I do have the "require password immediately after sleep or screen saver begins" option enabled in system preferences.

    Hi Kevin,
    You mention that you moved the TC's network up in priority, so you may have already done these things as well. Apologies in advance if that is the case.
    If you normally use your MBP with wireless, make sure that the AirPort connection is that top of the connections list in System Preferences > Network. Click on small gear icon at the bottom of list to put the Airport connection first in line to connect so the MBP will not look for an ethernet connection first.
    Click on the Airport connection to highlight it and then click Advanced. If you have other wireless networks that you can delete, use the - (minus) button to do so. Ideally, you'll only have a few networks displayed. Confirm that your wireless network name is first at the top of this network list.
    Make sure there is a check mark next to Remember Networks Joined. Leave the next two check boxes blank.
    Any help? My MBP connects consistently and quickly with these settings when the cover is opened.

  • Bluetooth devices lagging after wake from sleep sometimes.

    I have the Apple bluetooth keyboard, magic mouse, and magic trackpad. All batteries are charged and I have tried others by the way. This issue only happens sometimes, as it has happened before, but stopped for a few months, and now happened again tonight. What is happening is that my laptop (macbook late 2009 with  mac os x 10.7.2) wakes from sleep (all default energy saver settings set and I am able to wake the macbook with any of the bluetooth devices), and my bluetooth devices mentioned above are laggy for about 15-45 seconds. What i mean by laggy is that when moving the mouse across the desk after the login screen is already fully loaded, it jumps and is clearly not tracking like it usually does. The bluetooth trackpad and keyboard experience this same issue.
    Now the thing that leads me to believe it's bluetooth or software is that my macbook's built in keyboard and trackpad do not lag and function correctly as soon as the computer is woken from sleep and prompts me with my login screen. This also leads me to assume that it's not my computer running slowly or having too many processes or not enough memory. This problem happens even if I have no programs running (other than OS X's default processes). I have taken my macbook into the Apple genius bar thinking it was a bluetooth hardware issue, but they ran checks and confirmed that it was not and obciously, we could not get the issue to reproduce their at that time. I would love to hear from anyone who has experiecned this before, or is currently. We need to get Apple's attention with this issue because they have not listened to me when I submit a feekback form. This has been happening since 10.7.0 by the way. Thanks and happy holidays.
    macbook 6,1
    8gb memory
    mac os x 10.7.2 (happened on 10.7.0, and 10.7.1)
    -I can wake my macbook with my bluetooth devices
    -My built in macbook keyboard and trackpad do not experience this issue
    -I don't see the "connected symbol" when the computer wake (everything is already connected)
    -All default energy saver preferences set
    -Using apple's rechargeable batteries for all three devices
    -minimal processes running
    -devices function as normal after 15-45 seconds (it's not my desk)

    I've got what sounds like the same problem with my new unibody MacBook Pro.
    I've had the problem with both 10.6.1 and 10.6.2.
    I also find that a reboot fixes things. In my case, I can sleep/wake multiple times with
    no problem, but once the BT goes unresponsive upon wake, every subsequent sleep/wake
    will suffer the problem until I next reboot.
    I also discovered that in my case I can re-pair the non-responsive devices (two flavors
    of Logitech mice and an Apple wireless keyboard) while in sick-BT mode and they will
    work until I next sleep/wake, whereupon they will again fail to connect and my
    choice is either to re-pair yet again, or reboot and have the problem go away, at least
    for awhile.
    I'm trying to correlate my activity with my BT going out to lunch, but have yet to narrow
    it down definitively. I have one or two data points that make me suspect it goes south
    after I use VMware Fusion (Version 2), but I cannot yet rule that one completely in or out.
