New Macbook won't send DVI signal to Samsung 226B LCD monitor

I have the mini-DVI-DVI adaptor going into a Comprehensive DVI-D cable that goes directly into my Samsung monitor. My monitor won't show any signal from the Mac. I went nto Display and "calibrated" the signal but i never see a signal on teh SSung.

Sorry I didn't see this thread before or else I would have jumped on it.
The question is when, if ever, did you update to 10.5.5? Before or after you noticed the problem?

  • My new Macbook won't connect to my wifi network - it keeps saying "password incorrect" - but I've tested it on my phone and works fine, I've checked the password I enter is correct digit for digit - what could the problem be?

    you need to open the keychain access located in your utilities folder in the applications and once in the keychain on the left side click on the words system at the top and in the lower section click on passwords
    next look in the striped area for any passwords that say airport network password next to kind and highlight those and hit delete on the keyboard to remove them from the keychain.
    once you remove all of these airport passwords, quit the keychain
    turn wifi off then back on, select your wifi network from the list and enter the password telling it to save to keychain this should resolve your issue!

  • My Brand New MacBook Won't Start Up!!!!!

    My new MacBook won't start up - from the first time I ever switched it on!!!
    All I have is a black screen, the sleep light is on either permanently or flashing and now the install disc is stuck in the drive and I can't get it out!
    Help please!

    From my experience, resetting the PRAM and PMU do not work in this situation, at least with my MacBook. I have a feeling that 10.4.7 update didn't flash correctly or the firmware is buggy in some way.

  • New macbook pro wont send e-mail

    hi. i bought a new macbook last weekend. i have a macbook pro already. i use mail on both thru a company called easyspace. i bought my own website and now i have a number of e-mail accounts on it. now my old mac sends emails fine. however when i enter the settings into the outgoing server bit on the new mac it wont send. have been in contact with easyspace and none of their advice works. they keep saying type smtp.iomartmail.com use password and have port 25, or 110. i also tried smtp.easyspace.com also doesnt work. any ideas. i cant believe x2 macs cant work together suing same wireless in same room? thanks for anyones help

    Try backing up your Users -> yourname -> Mail folder, and then copying from one machine to the next the com.apple.mail.plist file found in Users -> yourname -> Library -> Preferences. If it still won't send, it is possible there is a limitation on your router as far as who can send mail and what ports they can use. Changing the MTU setting on your network preferences or IPv6 setting may help. Also verify your router has the latest firmware update.

  • Cant get macbook pro to send midi signals

    I have a new Macbook pro running 10.8.2 and I am trying to send midi singals to an Elation Magic 260 light controller. I have an M-Audio Midisport USB Uno connected from the macbook to the magic 260. I have installed the drivers for the uno, I can see it show up in my AMS screen and have created an external device for my Magic 260. When I go to test the setup...I get no sgnal coming from the macbook. Just wondering if anyone out there can offer some insight or advice?
    Thanks in advance!

  • Brand new macbook won't start up.  Help.

    I recently received a brand new macbook as a graduation gift about 3 weeks ago. All has been absolutely fine until yesterday. I checked my email in the morning, closed the macbook and left for work. When I came home, I opened the macbook and pushed the power button. The screen flashed for a split second and remained black. No start up sound. The power light is on, battery light on the bottom says it's fully charged. When it's plugged in, the charging light is orange. Otherwise, no signs of life. I have an appointment tomorrow to meet with someone at the macstore, but I'm impatient and highly stressed and wonder what the problem is and what will be done about it.
    Thanks.

  • New Macbook won't connect to existing network

    Hi there,
    I've just got my new macbook, and it won't connect to my wireless network. It comes up with an error message saying it cannot connect to the network. There's no hint of what the problem is. I have another laptop which connects to the network fine. Is it a password issue? And if so where do I go to change the relevant Airport settings?
    Thanks
    J

    The System Preference, Network, is where you change these things. However, it will only ask for a password when you try to connect, and it needs one. If it didn't ask, the network doesn't have a password. If you tried to enter one before, you can try deleting the Keychain that holds the wireless password. Open Keychain Access from the Utilities folder. Look for your network name in the list of items and delete the one with that name. If you have more than one, that may be the issue. Just delete them and start over trying to connect. Otherwise...
    We need to know more about the wireless network. Open, WEP, WPA? Type of router? What are the router settings?
    What are the MacBook settings for the Airport Network settings? Is it set to join automatic or preferred networks. Try adding your network as a preferred network and try that.
    The following are things that may work. Sometimes preference files prevent things like this, even on a new MacBook.
    There is also a preference file, /Library/Preferences/System Configuration/com.apple.airport.preferences.plist that controls some of the global Airport items. Try moving it to the desktop and then open system preferences and re-configure the network settings. Also there is preferences.plist. It has all of your network configurations and locations. If you move it, you'll have to add all of your network interfaces back into the Network Port Configurations and any Network Locations you may have made.
    You can always move them back if it doesn't help, but you'll have to overwrite the new ones that were created. You must be an admin user to do this.

  • Brand new macbook won't run off battery, only when plugged in

    I just go my new macbook last week and being new to mac computers, I didn't realize that it won't run from just the battery power until last night. The battery light shows it's fully charged. If i'm working with it plugged in and it becomes unplugged, it shuts down and when I reconnect the power cord, it resumes from the same webpage or whatever I was last working on. I opened up the battery compartment and removed the battery and then held the power button for 5 seconds, but that didn't fix the problem. Does anyone know what I might try or if something needs to be set up in order to run off the battery? Thanks! Leigh

    Hello leighdk,
    Welcome to Apple Discussions!
    You can by all means take some good advise from the people on this board in response to you problem.
    But here is the best advise, especially since you're new to Mac.
    Call Apple Care or take it back to the store and have them check it out. It is under warranty. You have 14 days from the date of purchase to return the Mac for a completely different or give it back because you do not like it. they may try to charge you a restocking fee but this should not be the case since there is an issue with you machine.
    Call Apple, see what they say... Then if you can't get it resolved then post back and maybe we can give you some sound advise.

  • New MacBook won't boot from external disk

    I have a new MacBook that I am trying to boot from an external disk that had the system from my first gen MacBook Pro. When I restart holding the Option key, and select my external disk, the system restarts again and won't let me boot from that disk. Is there something different with the OS (10.5.6) that is installed on a newer MacBook that won't allow it to boot from the same OS from an older MacBook Pro?
    Thanks

    golferx,
    Will any other Intel Mac boot from the drive? If not, it's possibly because the drive uses an Apple Partition Map (bootable for PowerPC Macs) instead of a GUID Partition Table (bootable for Intel Macs).
    To check: open to Disk Utility, select the hard drive on the left, select the Partition tab and look at the text at the bottom right corner of the window under Partition Map Scheme. If it says anything other than GUID Partition Table, you will need to erase and repartition it as such before it will be bootable.
    Just a thought. Hope this helps. Good luck!

    I can boot an prev gen MacBook and also my iMac (current gen). I took it to the Genius Bar and he could not get it to boot a new MacBook either and didn't have a solution.

  • New Macbook won't install Lion OS X

    I purchased a brand new Macbook Pro from the apple store last month, recently enough to receive the download of Lion free of additional charge. I went to the app store, was able to receive it for free, and clicked download at noon yesterday. By 5 pm, it had downloaded halfway. By 10 pm, it had stopped downloading, but just sat in the dock. I cancelled the download and tried it again today, and it won't even begin to download but it also hasn't given me any errors messages. I tried downloading a different, much simpler app to see if it was a problem with the app or my computer and this app also refuses to download.
    Why is my computer having such a hard time with this? It's brand new and hasn't been displaying signs of any other buggy problems. What can I do?

    I checked the hard drive utility and there were errors on the hard drive that needed to be fixed. But it wouldn't not let me repair the errors....
    Before you reinstall anything, be sure that your hard drive is fine. Boot up to the Install DVD and choose Disc Utility from the top menu ...verify/repair the drive. After you get the green light from Disc Utility, I'd suggest booting to your Install CD once again but this time holding down the 'D' key at start-up ...this will get you into the Apple Hardware Test.
    If things are fine here then go ahead with the installs/updates/backups as pedropablo suggests. If things are not fine, you'll need to make a trip to your Apple shop.

  • New iPhone won't send texts/make calls

    I broke my iPhone 5s a week ago, so I called *228 to put my number on an old iPhone 4 that my friend had so that I had a phone to use while I waited for my new one to come. My new phone is here and i have all my contacts on it as well as my apps, but it won't send text messages or make calls. I can't even call *228. I was wondering what I need to do so that this new phone is associated with my number again. Any advice would be greatly appreciated.

    Restart the phone by holding down the top/power button and the Home button at the same time until the device restarts.
    Log on to your My Verizon account and select "Activate Device".

  • New Macbook - can't send emails

  • New iPad won't send out emails on VerizonLTE or 3G network, but will do so on wi-fi - help?

    Been through the wringer on this one. Verizon or local cable  co. have not helped. New iPad will not send out emails while in LTE or 3g, but will do so in wi-fi. Have checked settings, restarted, reset settings, etc. Any ideas would be appreciated. BTW, I have an iPhone with Verizon and it sends out emails with exactly the same settings as the iPad while on 3g. This has been nuts.

    Hi all:
    Just found the answer to this thanks to Chris CA. In outgoing email settings, for some reason, the new iPad must have username and password entered even though it says optional. Once I entered that data, emails sent right out! The Verizon techs or my cable co. techs never suggested doing so after many hours of troubleshooting. This forum always has the real "experts". Thanks again, Chris.

  • A New Macbook pro with a Dell ST2310 23in. Full HD Monitor

    I have a new macbook pro hooked up to a dell Full HD monitor using mini display port to VGA connection. And the fonts on are not that crisp. They are a little jagged. The res is set at 1920x1080, 60.0Hz. Is there something I can do to fix this? I've been on dells site and there is not much support for mac users.
    thanks
    Karen

    Things would be working better from a digital connection. But if you must use VGA, check the Dell site or the user manual for how to "tune" the display. There is usually an AUTO adjust shortcut for this through one of the front panel buttons.
