Hold down the Option key as you clcik on the WiFi icon in the MenuBar.
Do you have a Dual-Band Router?

  • Macbook Pro Retina takes forever to startup.

    Hi guys, i recently bought a MBP retina but lately its been taking much longer than it use to when starting up. I remember that when i first got it the computer was only taking a couple of seconds but lately it has been more like several minutes. I was wondering if anyone else has been encountering the same problem and how would i be able to fix it? Also sometimes when i turn off my computer it restarts and says that it has encountered an error, after i turn it back on it gives me the following error report.

    thanks for your time!

    Uninstall "Avast" according to the developer's instructions -- not by dragging an application to the Trash or searching for files by name. There should be some kind of uninstaller. Reboot and test.

  • I just bought a 13" macbook pro retina display. I need to run films and presentations remotely. Does RemoteHD work on a machine without an IR sensor, or does anybody know what would work?

    I have a mid 2009 Macbook Pro and I have just bought a 13" macbook pro retina display. I need to run films and presentations remotely., i.e not sitting at the computer.
    Does RemoteHD work on a machine without a built in IR sensor, or does anybody know what would work?

    I can't vouch for this as I've never tried one, but I think this does what you're after.

  • MacBook Pro retina display - BlueTooth interferring with my WiFi conncetivity

    MacBook Pro retina display about 3 years old - when I turn on BlueTooth, it interfers with my WiFi conncetivity causing the browser to freeze while navigating pages on the web

    It
    seems to be a proximity issue - when I am very close (same room) as the Wi-Fi
    router, there is no issue. When I go into another room, the Bluetooth causes an
    issue. I was told that some of the MacBook Pro's had the Bluetooth and Wi-Fi
    circuitry on the same board - which they later changed. Has anyone else noticed
    the 'proximity' phenomena?

  • MacBook Pro Retina sound stopped working unless I put in and remove my headphones

    I have a MacBook Pro Retina and the audio only works if I plug in my headphones and then pull them out. I hear the ding when I turn the computer on but nothing else once it's booted. Does anyone else have this issue? I confirmed that my sound settings are correct.

    If you see a red light in the audio output port, then the headphones will be receiving the audio signal.  When you insert and pullout your headphones you are probably tripping an internal switch that was stuck and now enables the sound to come from the internal speakers.  This is a normal solution to that problem, but really should not occur.  A trip to the Apple store genius bar might be a good idea.  You still must be within the warranty period.

  • How do i find the wifi network and password for iphone 4s

    how do i find the wifi network name and passwordfor iphone 4s?

    Well Netgear will not know your password. The factory default user name for netgear is usually admin and the factory default is password is password.  Go to an internet browser and in the url windo type in 192.168.0.1 and if I am right a login window will appear.  Try the factory defaults.

  • My MacBook pro will take forever to shut off sometimes?

    When I want to tern off my MacBook pro sometimes it will take forever to tern off so I have to let the battery drain out and then when I use it again I have to plug it back in?

    never....ever.....let your battery drain all the way down.....it can do more harm to your macbook or battery....
    once you're up and running - open disk utility and verfiy your disk permissions - repair if needed then restart your macbook.....if problem persists, verify your disk and see if there are any errors....

  • When I boot up my macbook pro, it takes forever to start and I got grey screen...Help Please.

    Just a minute ago I tried to boot up my macbook pro...normally the grey screen pops up with the whirring wheel, and then my Lion log-in screen comes up and all is well.  This time, however, the whirring wheel spun forever on the grey apple screen. Then the wheel stopped and it went to a solid grey screen with apple...and nothing for about 10-15 seconds.  Eventually it came up. BTW, this was the 2nd time I tried to boot because the first time, the grey screen with the whirring wheel stayed up for several minutes so I rebooted.
    Anyone know what might be wrong? Thanks so much for your input!

  • Why does my macbook pro retina take 30 seconds for me to use it when i open the lid?

    For some reason it takes my macbook like 30 seconds for me to use it when i open the lid.  I cant move the mouse or anything until like 30 seconds go by is that normal or something wrong?  Its the new macbook retina display and never had this problem when i first got it.

    Are you running any applications when you open the lid, specifically any applications that are heavy on GPU usage such as iMovie or Photoshop?

  • Does the air vents in the MacBook Pro Retina take in air or blow out air or do both?

    I was using my MacBook when I saw a dust ball going near my air vents & and disappeared.

  • I spilled coffee on the MacBook Pro retina 15. All the buttons are sticky and touchpad does not work. What can I do?

    Im fron Russia. In service Center the men in blu shirt says that I need to pay a lot of money and change everything inside the mac.. Is it true?

    Afraid so. Liquid spills can kill your computer. Most of the components will have to be replaced, which is why it's such an expensive accident. You may want to get an estimate to repair and compare it with the cost of buying a totally new machine.
    Same thing happens all over the world - not just in Russia!

  • How do I connect a 2013 Macbook Pro Retina to an Epson Power Lite 61p LCD Projector?

    I am trying to attach an Epson PowerLite 61p LCD Projector to my 2013 Macbook Pro Retina, but I cannot find which type of adapter I need. I would assume whichever adapter is required it must connect via thunderbolt. However, I do not know if the required adapter is a "Mini Display Port to VGA Adapter," "Apple Mini DVI to VGA Adapter," or a "Thunderbolt to VGA Adapter." I would deeply appreciate your help and guidance. Thanks!

    It does not matter whether you get an Apple adapter or a third pary one.  What you have there is a Mini Displayport to VGA adapter, but as you know, your new MacBook no longer has an MDP port!
    Thunderbolt to VGA adapters do not exist but there are plenty of HDMI to VGA adapters out there:

  • Jaybird headphones and Macbook Pro Retina bluetooth connectivity issues

    I recently purchased the Jaybird Bluebuds X Premium headphones and for awhile it would connect to my new Macbook Pro Retina 15'' via bluetooth, but now it doesn't anymore. The headphones connect just fine to my phone (iPhone 4S), and other Macbook Pros (not retina), but they do not connect to other Macbook Pro Retinas. I was wondering if this was a connectivity issue with Macbook Pro Retinas and if so how can I get around it to connect the headphones again?
    Thanks

    Hey there LongHorn16,
    It sounds like your Bluetooth headphones aren't working with this one computer, but there is no issue with other devices that you have. I would start with these 2 steps from the following article:
    Restart your computer
    Sometimes a simple restart of your Mac is all it takes to get things running smoothly again. You may also want to try resetting your computer's PRAM and NVRAM.
    Reset your Bluetooth device
    Try turning your device off and then on again. If that doesn't resolve the issue, see if you can reset your device—refer to the documentation that came with your device for instructions.
    Bluetooth Quick Assist
    http://support.apple.com/kb/HT1153
    If it still doesn't work, then I would next use this article to remove the device:
    Bluetooth: How to Delete a Paired Device
    http://support.apple.com/kb/TA27116
    Then restart your computer and pair it again:

    Thank you for using Apple Support Communities.

  • Macbook Pro Retina Samsung vs. LG display

    I've been reading posts with people talking about the Macbook Pro Retinas coming with either Samsung or LG displays and have heard that the majority of LG displays are faulty while the Samsung versions are perfect. What is the deal with that?
    I ordered my Macbook Pro Retina on Aug. 10 and am wondering if Apple already fixed this issue and might be shipping only Samsung models? or is it still 50/50 chance of getting either LG or Samsung?
    I know I'm not the only one spending a ton of money on this machine but it doesn't seem fair that someone people get the faulty LGs and others get the Samsung. Has anyone tried calling Apple and seeing if they can request the Samsung version? not sure if that's possible but maybe worth a shot?
    Thanks!

    So are the macbook pro retina early 2013 version with LG panel having IR issue?
    Mine hasn't yet but time may tell. At the same time I asked a question on the endless IR thread and never got an answer: to what extent is how the rMBP being used driving image retention?
    I'm sure there are other variables but the one that comes to mind first is how bright is the screen run? I would imagine that a monitor set to full brightness (as one user who complained about IR did) would accelerate any tendency toward IR and the closer to "full-on" it's set, the sooner that would happen. I have mine set to "5" of the available range and for the first week, I ran the Image Retention Test in all its variations repeatedly without a hint of IR. We also don't know whether the LG at full brightness can illuminate an auditorium while the Samsung can only light up a room or vice-versa.
    Other variables could be: is the screen saver used; how long before it kicks in; is the rMBP the only computer so it's used constantly; is it ever powered off or is the monitor just allowed to sleep?
    Based on those thousands of posts, the original LG's appear to be more prone to IR than the Samsung, but there hasn't been the same flood of complaints with the LG SJA2's, at least not yet. At the same time, there hasn't been any attention I could find about contributing factors either.
    And notably,  way back when the Samsung started to be the Holy Grail, I don't remember complaints about color problems; that seems to have cropped up recently.

  • I use a macbook pro retina. before i upgraded to maverick my windows stayed the way i put them. now after upgrade i have to resize every time i change the window. i use a 32in. monitor and use it full screen.

    I use a macbook pro retina.  I use a 32 in. monitor and use it full screen. I size the screen manually.  Since i upgraded to maverick, I have to resize the screen each time I change windows.Before the upgrade the screen stayed where I put it.

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device. 
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
    Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
    When you see the gray Apple logo, release the shift key.
    If you are prompted to log in, type your password, and then hold down the shift key again as you click  Log in.
    *Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.
