Macbook will not detect projector?

Just had problems today and spent an hour with an Apple tech. Gave up, called Dell (India) gave up.  Rebooted computer and low and behold it worked.  That after trying just about everything and being totally convinced that the problem had to be with the projector.  So if all else fails, reboot.

  • Before I updated today to Lion OS, my multiple monitors worked fine. Now my macbook will not detect them.  Is there a solution for this?

    I've been running multiple monitors for over a year on my Macbook.  Updated today to Lion OSx and well Steve, it didn't just work.  My macbook will not detect my three external monitors, and after scouring the last hour on Google of how to remedy this and trying the basic suggestions of restarting, unplugging, replugging, to no avail.  Anyone else have a similar problem since they've upgraded to Lion OSx?

    Read the first extract for the definition of backup snapshots and how they are handled by the OS.
    2-Shoud I delete older backups? If for example, all I need from Time Machine is the latest backup done today, can I get rid of the 2+ yeras of backups, or do they not take up that much space?
    No.  Time Machine should be on a separate HDD and will take care of deleting backups when necessary on that drive.
    3-Back to the issue, considering I don't have access to a an apple store for the next few months, what is my best plan of action?
    I would consider installing a larger internal HDD.  Capacities to 1 TB are now available.
    4-I am considering buying a new macbook 15inch, and get more space, however, I'm scared that the same problem will happen again. Is this common on all macs? Will using Time Machine to "Restore" my backups bring along the issues as well?
    All Macs using Time Machine will experience the same conditions.  The problem is that many users do not under stand what 'Other' is and that leads to confusion.  There are many essential OS files in that category that should not be touched as well as some user files.  The issue is not to reduce 'Other' as such, but reduce the total amount of data on the HDD if space is becoming a premium.

  • My macbook will not detect displays

    I have a late 2008 MacBook and I am having trouble connecting an extenal display. I have been watching all the Youtube videos and everyone says to go to the arrangement tab. On my computer the Arrangement tab does not show up. I know that this is because the computer tells my I only have one display hooked up(which is not true). At no point have I been successful getting this to work but my roommate used the exact same set up(cord & adapter) and was able to get it work. If anyone has any idea on what the problem is PLEASE RESPOND!!!

    I have tried to connect it to my TV with my mini display port to DVI and a DVI to S-video and nothing...
    I don't know what your DVI to S-Video adapter looks like, but unless it's a boxy converter device, it won't work. You need a converter box to create an analog S-Video signal from a Mini-Displayport's digital-only output. The converter boxes I'm familiar with require VGA input rather than DVI input, but there may be others I don't know about. If you are using a simple DVI -> S-Video adapter such as the one offered on the Apple Store, it won't work with your MBP to deliver S-Video to a TV set.
    ...and I have tried to connect to a projector at my work with the mini dislay to DVI cable to VGA and nothing.
    A MDP > VGA adapter and a standard VGA cable are what you need for that. Converting first to DVI and then from DVI to VGA makes the setup unnecessarily complicated and may be the reason why it doesn't work for you.

  • Macbook will not detect external display

    Was using a $7 aftermarket minidisplay port to HDMI cable with success for about 2 months with no problems detecting external display.  Started having problems (it would randomly detect until it eventually would not at all) and tried all solutions I could find in discussion boards to no avail.  I recently bought a $40 cable from the apple store and it worked fine for about a month and now it only recognizes my external display about 50% of the time (which is how the problem began the first time).  Very frustrating!  What is the deal here? 

    Did you have any luck resolving this? I have had exactly the same issue when updating the EFI Firmware to Version 2.8 (the latest for a Mid-2013 MacBook Air 6.2 model) - MBA61.0099.B12
    I've tried flushing the NVRAM/PRAM and also resetting the SMC but no joy. I'm trying to drive an AOC Q2963 monitor using a display port connector. Annoyingly, I don't think there's a way to rollback to a previous firmware version.

  • Late 2008 15 inch Macbook Pro will not detect external projector

    I have a Toshiba projector that I am trying to hook up to my Macbook Pro for a presentation tomorrow. The computer will not detect the display. I'm using a DVI cable connected to the Mini Display Port. I know I've got the projector on the right input as my white Macbook with mini DVI will detect it but not display it properly (all green).
    I've tried shutting down and disconnecting and everything. I need this to work asap.

    Have you checked the screensaver and power settings, sleep display etc in the System Preferences?
    You can throw this mega cocktail at it, see if it cleans up your problem.
    Download the free OnyX here
    http://www.titanium.free.fr/
    Run ALL the maintainence and cleaning aspects, , especially the caches, you can cancel the reboot in between.
    Finially run the Verify > Preference file check/repair and then reboot.
    This should clean out all your caches and whatnot.
    Then look at this support article about resetting the SMC/PRAM

  • ITunes on my MacBook Pro will not detect my iPad

    I have a MacBook Pro and the latest version of iTunes - it detects my iPhone 5 but will not detect my iPad (2). I want to back up my iPad on iTunes because my iCloud is full, and I am thinking about getting a new iPad. Any suggestions??

    We have no idea which version of OS X you are running, so here are two support articles about your issue.
    iOS: Device not recognized in iTunes for Mac OS X - Support - Apple
    Mac OS X v10.6: iOS device not recognized in iTunes after restart
    Sometimes it's as easy as quitting iTunes, restarting the Mac, restarting the iPad. Give that a try if you haven't done so already.

    Everytime i plug it in it charges, but iTunes will not find my phone. someone please either help me or shoot me because its driving me INSANE!!!!!!! i followed every step that apple says to do and have also looked at other peoples answers and nothing is fixing this!!!

  • Windows 7 airport utility will not detect time capsule

    Hi, I have a current generation time capsule and I am having problems connecting to my Windows 7 home premium PC. The time capsule connects and works perfectly using my Macbook. My set up is this: DSL router conected to the time capsule via ethernet cable. I can get the time capsule to pick up wireless and connect to my PC, but upon opening the airport utility it will not detect the time capsule at all. I have trolled the internet for about 3 hours trynig various things, none of which have worked. Has anyone had this issue and resolved it?

    The airport utility has nothing whatever to do with disk access.
    It helps having bonjour available in the computer. And the utility should be able to bring up TC setup.. although as noted.. apple have already bypassed windows as it is too old. The new TC requires v6 utility.. the version for windows is 5.
    None of that is relevant to opening the TC hard disk.
    -If this is not the case, can you please advise on how to access the storage on a windows 7 PC
    Did you follow the instructions from my previous post.
    Open your windows explorer and type into the address bar,
    \\TCname or \\TCIPaddress
    Where you replace TCname with the actual name of the TC.. your nice new short SMB compatible name.
    Or use the IP address of the LAN on the TC.. by default 10.0.1.1
    If you did this and it failed, you need to ping the TC by name and by IP address from command window..
    Does the TC respond to pings??
    If so it should be able to open the TC disk.. but you will probably have to use the IP address not the name which is likely illegal.
    I also mentioned the issue of SMB names..
    Please tell me what is the name of your TC as you set it up in the Mac..
    Does it look like this.
    Fred Blog's Airport Time Capsule.
    If so it is too long.. it has spaces and it has an illegal character.. from windows the name should be short, no spaces and pure alphanumeric.
    Please reset the TC to factory and start again.. you can use the airport utility in the Mac.
    Do not use apple suggested names.. which are WRONG.
    Use names like TCgen5
    And for wireless TCwifi
    Then try again with the windows.
    If you continue to have issues, try using ethernet to the computer from the TC instead of wireless.
    Make sure ipv6 is on and set to link-local or the PC equivalent of that.. I will need to look that up.

  • HT1386 iTunes will not detect my iPhone(5s) after the most recent update.

    Ever since i updated iTunes it will not detect my iPhone, every time i plug it in it asks to trust the computer which I always use to sync my iPhone. Every time i select "trust this computer" and it still won't detect it. PLEASE HELP.

    Hello fercho965,
    Sorry to hear that your iPhone is currently not recognized by iTunes.  I found an article with steps you can take when you experience an issue like this.  I wasn't sure whether you were using a Windows or Mac computer, so I included the respective articles for each:
    iOS: Device not recognized in iTunes for Windows
    http://support.apple.com/kb/TS1538
    iOS: Device not recognized in iTunes for Mac OS X

  • My imac will not detect external monitor after recent update. Is there a way to fix this?

    I have a VGA monitor plugged in to my imac using the VGA adapter to the mini-DVI.  All was working well.  Since I updated over the weekend, the computer will not detect the monitor.
    Any ideas how to fix this?

    Pcantin wrote:
    I have tried another VGA monitor and that failed as well.  Since you don't think the update was the cause, it may be that the adapter I am using decided to call it quits.  I will see if I can find another and test that out.
    I will look into the external drive idea as well.
    Thanks for your help on this.
    I didn't think about the adaptor, but you should at least visually inspect both the adaptor and the cable at both ends. If one or more pins got bent even slightly the connection might fail. The cables can also fail internally. Replacing the adaptor and cable may be the quickest thing to do initially. If you want to try to save money, first replace the adaptor, and if the problem persists, then go replace the cable (or vice versa).

  • IPod 4th gen grayscale will not detect usb connection.

    Hello everyone, I have a iPod 4th gen grayscale and I'm running Ubuntu, everything has worked well for about a year now, I have been syncing my iPod through VirtualBox with Windows XP for as long as I have been using Linux, though, for some reason, my iPod has stopped noticing my usb being connected, I know it's not the usb cable, or the usb ports, I have restarted my iPod and put it into disk mode, still no luck, restarted my computer, Linux will not detect anything plugged in, nor will Windows, though my iPod shows the battery charging when plugged in, but iTunes will not detect the iPod.
    I have switched the hard drive of the iPod out seeing if that was the problem, still no luck, my car dock will pick up the iPod and play music, so will my other docks, I thought it might of been Linux at first, so I plugged it into my desktop with Vista, it also will not detect it.
    Does anyone have an answer to this riddle?

    A bad USB hub will cause the problem ... are you using it ??

  • HP installer will not detect networked LaserJet MFP M1536dnf just on some PCs

    Hello,
    this printer/scanner was working fine (printer still works fine via a Windows print server). Then scanning (via network) stopped working on one PC (Windows 7).
    Tried to uninstall drivers / HP software and reboot. Then tried to install again - HP Installer will not detect printer on the network no matter what. I can ping the IP of this printer, access its web interface without any issues on the same PC. Tried specifying IP address in the installer - does not detect, the same issue with MAC address. 
    Had a Windows 8 machine with drivers / software installed on it, tested - scanning still worked fine on that PC. Tried to remove HP software to see if problem will appear. And it did! I cannot install the same software package which I still had in downloads - it will NOT detect the printer on network.
    Upgraded printer firmware - no change, even though I don't expect this to be a printer issue as it worked fine until I have uninstalled software on this W8 machine.
    Tried using HP Scan & Print doctor. That thing doesn't see printer/scanner installed and only suggest to download and install software which is not helpfull at all.
    I also tried extracting HP installation files and finding *.inf files which could be used to add scanner via Windows directly, but haven't succeded with that (I would also be not sure how to specify network IP address in such a case anyway).
    Any help is MUCH appreciated. We are kind of stuck...
    Thanks!

    Hi,
    Run some diagnostics and see if any issues are discovered.
    There have been reported issues with the NVIDIA 650 with some of the HP PCs. Additionally, most models of the NVIDIA 650 require a 400 watt power supply as the minimum and some models require a PCI six (6) pin power connector which the 300 watt power supply in your PC is not provisioned.
    There is a BIOS update posted for your PC so you might want to consider installing that update.
