Plug 24" LED Display into Mac Pro, Still Charge MacBook Air?

Just set up my Mac Pro using the 24" LED Display I used to use with my MacBook Air. With the USB and Mini DisplayPort now plugged into the Mac Pro, could I still plug the MagSafe power cable into the Air to charge it in a pinch, or is there any reason I'd need to unplug the Mac Pro connection first?
(Rather be safe than sorry...)

Thanks much! Unless anyone cares to chime in with an opposing view, I'll be using the 24" as a spare MagSafe to recharge the Air when I'm at home...

  • I have 2 Apple Cinema LED Displays (no Thunderbolt) and a new Macbook Air (with Thunderbolt).  Is there a way to connect both of these monitor to my Macbook Air?

    I'm trying to use 2 older Apple Cinema LED Displays in a Dual Monitor configuration with my Macbook Air.   It is a new macbook air and supports Thunderbolt.

    Look for minidisplay connectors/adapters that  that fit the inputs on the display, such as this example:

  • Problem: Plugging an LED-display into my MBP 15"

    Hello!
    I recently bought a BenQ G2222HDL 21.5" LED Monitor and I have encountered some problems when trying to connect it to my MBP via the Mini DisplayPort to DVI-adapter.
    My MBP (spring 2010) won't find the display but when I try to connect the display to my brothers MB (spring 2009) it works immediatley and it finds the display in no time.
    Is there any differences between the Mini DisplayPort on older an newer models of MB?
    Have anyone out there encountered the same problem? Anyone got any suggestion on how i can make it work?
    Thanks!

    When I have to re boot to get a screen that I can see, it gives me a error report, but unfortunately I don't have a apple store anywhere close by, otherwise I would just drop off and see how screwed I would be, since I have no apple warranty nor apple care ;-( !

  • Can i use Apple 2005 20-inche cinema display on Mac pro ?

    can i use Apple 2005 20-inche cinema display on Mac pro ?

    If the display has a DVI connector it will plug into the Mac Pro directly.  If it uses ADC (Apple Display Connector)
    <http://upload.wikimedia.org/wikipedia/commons/0/09/AppleDisplayConnector.jpg>
    you will need a DVI to ADC adapter

    Did you purchased the Full Perpetual License from Adobe for $149.00?, if so then what has happened is that you probably downloaded the Creative Cloud trial version which has now expired.
    The license key for the perpetual version will not be accepted to activate the CC version.
    Uninstall the existing Lightroom and then download the one available from the link below. The uninstall process will not affect your Catalog, Preferences or personal files but will just remove the application. Install the new download and you license key will be accepted.

  • Mac pro still hangs on the blue screen on start up.

    Hi.
    my mac pro still hangs for ages on the blue screen before the login page where i input my password appears.
    i've tried starting up in command-V and that didn't work.
    i thought snow leopard was meant to improve, it has just slowed my start up down greatly!
    could someone please advise on how to fix this?
    thanks
    Dan.

    Hi boom,
    Have you tried downloading and re-applying the latest Combo update?
    If not, go to the apple download page, find the Combo update (couple of hundred MB) and install it.
    This has fixed various issues in the past for numerous users... it might do the trick for you.
    After it's installed and rebooted, repair permissions and reboot again.
    Also check to see (using software update) if there are no firmware updates available for you.
    And, make sure the OS drive's root is clean, just the basic Applications, Library, System and Users folders, no other mess. If there are 'Previous System' folders from earlier Archive & Install situations you might want to remove those.
    Finally, if you upgraded from a PowerPC to Intel using the Migration Assistant the symptoms you are describing are very common, the migration assistant well... it ***** :/

  • Can I use 27' iMac(Later 2009) as a display for Mac Pro(future 2013)?

    Can I use 27' iMac(Later 2009) as a display for Mac Pro(future 2013)?

    See > http://support.apple.com/kb/PH11302
    To be able to use the iMac as an external display, the Mac Pro should come with a Mini DisplayPort or Thunderbolt port, so think that it will include Mini DisplayPort or Thunderbolt, although we don't know anything.
    To connect the iMac to the Mac Pro, as your iMac has got a Mini DisplayPort, you have to use a Mini DisplayPort to Mini DisplayPort cable (Thunderbolt is compatible with Mini DisplayPort cables, but Mini DisplayPort isn't compatible with Thunderbolt cables). Then, just follow the steps of the page above to use the iMac as an external display

  • New cinema display on Mac Pro monitor keeps turning off/going dark. Support told me a keyboard shortcut (something like option R L)... I'd appreciate it if anyone knows it. I had this problem when i 1st bought it 2 months ago.

    My new cinema display fro mac pro just went dark. When I 1st bought it, the display wouldn't turn on.I called support and they gave me a keyboard shortcut - something like Option+R+L - that you held down for 2 restart cycles. Then it magically turned on. I can't remember the sequence and I'm afraid to guess! I'd appreciate if anyone knows the trick. I'm also wondering if I should bring this display back...

    Cassandra from Apple Support ROCKS!!!! She's a supervisor somewhere and should have a raise. Pleasant, smart and professional with a customer who wouldn't take "I don't know" for an answer.
    If your cinema display goes dark:
    1. shut down computer
    2. restart
    3. immediately hold down Command-Option-P-R keys simultaneously for a few minutes (seems forever)
    4. keep holding keys for 2 startup cycles
    5. release and go back to work if you're lucky to have a restored screen

  • Screen dims randomly with Mac Pro - NOT a Macbook

    After upgrading to Mountain Lion, my screen will dim randomly when watching movies or YouTube.  This is on my early 2008 Mac Pro - not a Macbook Pro which seems to have this problem commonly.  I've searched and searched and lots of people have this problem with a Macbook Pro (battery saving feature or something) but there are no options to defeat screen dimming that I can find for a Mac Pro!! Mountain Lion just keeps getting worse and worse!
    HelP!

    Hello, thanks for taking the time to help me out!
    This is a 2008 MacPro (2x2.8 GHz Quad-Core Intel Xeon) running Mountain Lion OSX 10.8.4.
    I am running two monitors: a HannsG HH281 and a Hewlett PAckard HP w2408h.
    When this first was happening back in March 2013, I thought it had something to do with the ambient light sensor on the HP (the HannG doesnt have a light sensor), but it also might have has something to do with the dynamic contrast on the HannsG.  I had shut those features off, and I actually hadn't had this problem in a while and there has been a few Mountain Lion updates since then.
    I just tried to reproduce this by turning on/off the dynamic contrast on the Hanns G - did not get the problem
    again.  I also just turned the ambient light sensor on for the HP, and again, the problem did not occur.
    So it is hard to say if the problem is gone away or not or if it just is not showing itself at the time being?

  • Can my Mac Pro drive my MacBook?

    Can my Mac Pro drive my MacBook so i use the MacBook monitor/keyboard but the MacPro’s hard drives, software? How do I do it?

    There's a free and much simpler way than Apple Remote Desktop since that is enterprise level software (for schools and businesses.)
    All you have to do is go into the Sharing system preference on your Mac Pro and turn on Screen Sharing.
    Then you connect to your Mac Pro from your MacBook desktop. On the MacBook in the Finder desktop, go into Network, select the Mac Pro, and there will be a button at the top of the Finder window for screen sharing. Click it, log in, and you will be controlling the Mac Pro from the MacBook.

  • I plugged my IPAd 2 into my computer to charge and it said i could sync my ipad 2 to my ipad 1 so i did for music ect yet when i went back on my ipad 2 ALL of my important notes i took for school were gone off of notes! how do i get them back!?

    I plugged my IPAD 2 into my computer to charge and a window popped up saying (through itunes) i could sync from my ipad 1 to get music and other photos ect. I pressed yes and then i went onto my ipad 2 after it was done and ALL of my VERY IMPORTANT notes for my school reading were GONE. HELP!? how do i recover my notes?!

    Did you create these notes in the iPad notes App ... I assume?
    This support article will explain how you can restore from a backup - which is what you have to do in order to have any chance of recovering your note.
    How to backup and restore from a backup
    http://support.apple.com/kb/HT1766
    But you have to remember, that you will lose any of the notes that you have taken since the date of the last backup. If you synced your iPad last week, then you will lose a whole week of current notes - or whatever notes you have created since your last backup. When you restore from a backup - you restore everything in that backup onto the iPad - that was on the iPad on the time and date of the backup.
    If you backup every day, then all of your notes should be recoverable from the backup - except for any notes that you took since you last backed up. There is no foolproof way to recover everything once you start taking more notes or creating new documents or whatever that you do in an app unless you are syncing those notes with iCloud and backing up all of the time or unless the app is set to sync with iCloud as you work on the files - like in Pages, Numbers or Keynote - Apple's iWorks apps.
    If you decide to restore from an iTunes backup you should turn off at sync before you try restoring because iTunes will want to backup your iPad right away when you plug it in and you will lose your old or last backup.

    I have it set on manually manage music and videos. So there is no automatic syncing going on or anything like that. Yes iTunes was open and when i plugged in my phone i could see all the music and everything on my phone, everything was working like it was supposed to, I didn't have a problem until I unplugged the phone. 

  • Do I go with the MacBook pro or the MacBook air? I'm going into 8th grade and were required to have labtop. I Also edit videos for my YouTube chanel. Which should I get 13 inch model.

    MacBook Air: thin, light, fast SSD storage. Cons: not upgradable, expensive.
    MacBook Pro: cheaper, upgradable, better graphics card, more storage and RAM for the buck.  Cons: not as light
    you'll get more for the money with the MacBook Pro. the Air is better as a second computer for people.
