10.9.5 Maverick won't recognize projector

I have a 2013 MBP, running 10.9.5 to a Epson PowerLite Home Cinema 8350 projector.  The projector give me "No Signal"  I am running a cord from the Thunderbolt port to the HDMI port no the projector. 
I have tried:
both thunderbolt ports and both HDMI ports.  The HDMI ports on projector work with a PC.  The thunderbolt ports and cord works when connecting to a plasma and an LCD TV
I have gone to display, and there is no "arrangement " tab.  I have hit option and clicked detect displays.  I have hit F7 with option, shift and control and command.  Ditto with F3.  I have reset the monitor.  I have reset the PRAM on laptop, I have reset the SSC.  I have booted into safe mode.  I download the "display menu" app and set the resolution to 1080, and every other resolution available.  I have restarted the MBP and the monitor, and plugged and unplugged the cord in every conceivable order. 
Please help, it should not be this hard to make a presentation.

  • IMac with Mavericks won't recognize new 60D

    iMac with Mavericks won't recognize new 60D

    No drivers are required on the Mac to use the camera.  The Mac will natively recongize the camera.  
    You can install Canon's supplemental software or you can use the Apple provided software or 3rd party software.
    However... when you connect a camera to a Mac and it recognizes the camera, you *can* configure what you want the computer to launch.  By default, a Mac will usually launch iPhoto.  
    If you open iPhoto (do this EVEN if you don't want to use iPhoto) then go into iPhoto -> Preferences and look at the "General" category.  You'll see an option that reads:  "Connecting camera opens:" with a selection menu next to it.  You can use that menu to pick what you want your Mac to do, then close and quite iPhoto.
    When connecting the camera to the computer, do the following:
    Turn the camera off
    Use the supplied USB cord to attach the camera to the computer (some caveats here... I'll mention them below).
    Power the camera on after it's attached.
    About those caveats on step 2.
    The reason I say "use the supplied USB cord" instead of use any USB cord is because if you're like me... you've got LOTS of USB cords laying around.  Some of these come with devices that use USB for charging purposes.  And some of those USB cables ONLY bother to wire the power supply pins and not the data transfer pins.  In other words... it looks like a normal cable, but wont actually allow for data transfer.   You will need to take care to make sure you're using a proper cable.
    Next I should caveat the use of USB hubs.  Whenever you're having a problem with a computer not recognizing a USB device, it's a good idea to disconnect extraneous USB devices that have nothing to do with your issue AND if there's a USB "hub" involved... bypass the hub and connect the camera directly to a USB port on the computer itself.  
    I use a USB hub and this particular hub is reliable... but truthfully I had to buy three different hubs before I found one that worked reliably.  I've discovered there are a lot of flakey hubs on the market.  When in doubt... bypass the hub.  If you find that you can get your computer to recognize your camera on a consistent basis if you bypass the hub then you can direct your attention to finding a reliable hub.
    That's the end of the caveats.  
    I wrote a response to a user with a similar issue in which I detail the steps to use the Mac's System Information utility to determine if the camera is showing up as connected to the camera.  You can find that post here:

  • Mavericks won't recognize my lacie external hard drive

    I've been using a LaCie external hard drive for my Time Machine backups and it's been working fine until a couple of weeks ago. Mavericks no longer recognizes the drive. I tested the drive out on a non-Mavericks Macbook and it booted up fine. I see there are issues with this, but wondering if anyone has a work around or if you've found there is a fix I can do? Really frustrating to not be able to access my archives or be able to back up my work!

    Apple doesn’t routinely monitor the discussions. These are mostly user to user discussions.
    Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

  • OS X Mavericks won't recognize firewire device

  • MacBook won't recognize projector

    Hey-- I have an Optoma projector and a MacBookPro running Snow Leopard. I can't seem to get the projector and the computer to detect each other. It works fine on an older pre-Intel laptop. I have the right VGA adapter, and I've tried rebooting things in various orders, but to no avail. Help?

    I have exactly the same problem with my MBP 15". The same projector works fine with an old white MacBook, so it's not an Intel issue. I suspect that it's the DisplayPort (the white MacBook has a mini-DVI output). I'm using an Apple DisplayPort -> VGA adaptor. Plugging my Apple 24" display into the MBP works fine, but that is directly using the DisplayPort (no adaptor). If I reboot, the computer will recognize the projector, but it's a pain in the backside to have to do that.

  • Maverick won't recognize iphoto! help!!

    i just upgraded from lion to maverick and now it says it cant access iphot beacuse i had an old version 9.1. ok?! so now what? how do i upgrade so it can acces it?

    Upgrade iPhoto on the App Store.
    The iWork apps are free with a new iOS device since 1 SEP 2013. They are free with a new Mac since 1 OCT 2013. They are also free with the upgrade to OS X Mavericks 10.9 if you had the previous version installed when you upgraded.

  • Mavericks won't connect to UPS

    New iMac.
    Mavericks won't recognize Power Inspired VIS1000B ups - 'UPS' option does not appear in Energy Saver preferences pane.
    Tried calling Apple support, no knowledge available .....

    How about just contact support at the UPS manufacturer - http://www.powerinspired.com/vis1000b-1kva-sine-wave-ups-system-p-1781.html
    They claim to provide software for that model for Windows, Unix, Linux and OS X, so it may be an instance where you actually need to use their tools instead of the default OS X facilities.
    P.S. their download link is http://www.power-software-download.com

    I just upgraded to OSX Mavericks and when i use the gestures on my magic track pad it responds oddly.  Sometimes it won't recognize when my simple gesture of scrolling through a document.

    Gestures is not working like it did before. The side to side, forward back swipe, is very picky. Sometimes it takes four or five tries before it works. And yes I know how to do it. I have had a magic trackpad for about one year. And was greatly pleased by how it worked, BEFORE Mavericks. It has has indeed changed.

  • ITunes & iPhoto suddenly won't recognize my iPhone 4S

    I've made some purchases recently both in and out of iTunes, so I decided I wanted to download them to my phone this morning. I plugged in my iPhone 4S (v7.1.2) and opened iTunes (v11.3), but iTunes wouldn't recognize the phone, even after I rebooted the phone, checked the cable, rebooted and reinstalled iTunes, etc.
    My phone is charging, so my MacBook (which is running Mavericks OS 10.9.4) is definitely connecting to it.
    But when I tried iPhoto, it won't recognize my phone, either. I rechecked the cable. It seems to be fine. I even tried a new cable. No dice.
    What's going on? Anyone else experience this? It's the first time since I first starting using iPhones in 2008 that I've ever had this kind of problem.
    Thanks in advance!

    What do you mean OS X won't allow you to uninstall iTunes?
    Very rarely is needing to uninstall iTunes on a Mac before reinstalling required as is required with the spagetti code involved with Windoze.

  • Erased mac book pro (2009), how can i reinstall osx?  it won't recognize any old system disc

    erased mac book pro (2009), how can i reinstall osx?  it won't recognize old system discs

    Did you try:
    Install or Reinstall Mavericks or Mountain Lion from Scratch
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    OS X Mavericks- Erase and reinstall OS X
    OS X Mountain Lion- Erase and reinstall OS X
    OS X Lion- Erase and reinstall Mac OS X
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.
    If you don't have the original discs that came with the computer, then you can install the retail version of Snow Leopard:
    You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mavericks if your computer meets the requirements.
         Snow Leopard General Requirements
           1. Mac computer with an Intel processor
           2. 1GB of memory
           3. 5GB of available disk space
           4. DVD drive for installation
           5. Some features require a compatible Internet service provider;
               fees may apply.
           6. Some features require Apple’s iCloud services; fees and
               terms apply.

  • MacBook Won't recognize cameras

    I just upgraded to a MacBook Pro Retina 15 with Mavericks 10.9.5. Everything is freshly updated and no other performance issues with the new machine.
    The computer won't recognize either of my cameras, neither a Nikon Coolpix S8100 nor my new Nikon D810 when connected via the USB cable. 
    No program will recognize the cameras being connected: not iPhoto, Nikon ViewNX2, nor Image Capture---all three latest versions. I have tried selecting  the preferences to have either iPhoto or View NX2 open when the camera is connected but it still doesn't work.
    I can take the SD card out of the Coolpix and the MBP will read it in the built in card reader and I can manually drag files into both iPhoto and ViewNX2. I don't have a flash card reader for the Nikon D810.
    My two drives for backups and photo storage connect and run perfectly
    I had no problem with my old MBP 15 running Snow Leopard recognizing both cameras.
    Anyone else had this problem?

    So you're essentially trying to install the XP operating system on your Mac?
    You first need to install Boot Camp or Parallels and partition your drive, allowing for there to be a drive to install windows on.
    During that partitioning process, it eventually prompts to insert the installation disc.

  • Mavericks won't accept my password and I can't authenticate any actions

    Following my recent mishap (https://discussions.apple.com/message/25466460#25466460), I successfully reinstalled Mavericks on my MacBook Pro.
    Here's the new problem. It won't recognize me as the administrator. I'm the only account in my laptop, and when I try to authenticate any changes in the system preferences, I type my admin account and password, but it won't accept it! The password hint even shows up, but it still won't accept my password!
    What really bothers me is that whenever the window opens, the Name: part is empty. Before, my account name is automatically there, and all I need to do is to enter the password! I am super super worried right now, because I don't want to reinstall Mavericks again.
    Thanks!
    P.S. On a side note, I was not able to oversee the completion of the reinstallation. I was out during the last few hours it was being reinstalled.

    more details about my problem:
    following the reinstallation, I just wanted to check if the system file I had messed around with (the one mentioned in http://idevicedailys.com/os-x/howto-use-candybar-os-x-mavericks/) was still okay. But this shows up:
    I tried using other sudo nano commands like sudo nano /etc/hosts but the same result happens. Please, I am super super desperate!

  • ITunes won't recognize iPod Nano (1GB, 1st generation)

    I have been having problems Sync'ing my iPod nano with iTunes, however, the more I read help articles and follow the steps, the worse the problem gets. (I'm on a PC using Windows XP)
    I've gotten to the point where I updated my iPod software in Disk mode (up until then it was being recognized only in Disk mode), but when iTunes failed to recognize it when not in Disk mode I preceded to restore my iPod to factory settings, as instructed in the help articles.
    Now, up until then, I still had music in my iPod, and I was being able to charge it and listen to my music even though I couldn't sync the iPod anymore. After restoring, I not only lost my music (which I was aware of), but it STILL did not fix my problem. So I started to get annoyed.
    I then noticed that my iPod was being recognized by My Computer, just not by iTunes, so I began to perform the steps indicated in the following article:
    http://docs.info.apple.com/article.html?artnum=93716
    I restarted my iPod service - no luck
    I removed iTunes - no luck
    I emptied my Temp directory and restarted...
    That's when iTunes stopped recognizing my iPod altogether, not even in Disk mode. Not only that, but it seems to have affected the iPod itself, since it won't turn off or exit Disk mode anymore. So now I'm scared of going though with any more steps on whichever "help" articles and making the problem even worse than it already is (if that's possible).
    The only other information I can provide is that windows is still recognizing my iPod, no problem, and when I connect my iPod, iTunes actually launches... but DOESN'T recognize a thing. So I ran a diagnostics using iTunes and here's what I got (iPod diagnostics):
    Microsoft Windows XP Professional Service Pack 2 (Build 2600)
    INTEL_ D945GCL_
    iTunes 7.3.2.6
    iPodService 7.3.2.6 is currently running.

    Connected Device Information:
    IPOD (H:\), iPod nano running firmware version 1.3.1
    All green lights, and as you can see, according to iTunes, NO PROBLEM! Except that it won't recognize the iPod that the disgnistics says exists and reads... ?!?!?!
    If anyone could shed some light on my situation, i would be VERY greatful!

    My IPod Nano will charge when connected to my computer but it won't come up on My Computer or iTunes. So I can't update the songs. I've already tried reseting the iPod. Does anybody know what I can do to fix it.
