DVI external display freezes while charging MacBook Air.

My Samsung SyncMaster SA300 freezes my MacBook when connected, but when I unplug the charger for the MacBook, it works fine. Very annoying...

You can, but, some programs still can cause the display to come on because of their demands of the graphics chip. So you have to sometimes keep an eye on the display so it doesn't overheat the keyboard or run the battery low.

Sounds like you may have been in extended display mode. If so, all you had to do was drag a window to the projector display. Or, if you wanted mirrored mode, in display preferences select check mirror display.

Whats the maximum resolution resolution supported @ 60 Hz on an external display for mid 2014 macbook pro retina 13 inch ?

whats the maximum resolution supported @ 60 Hz on an external display for mid 2014 macbook pro retina 13 inch ?

I don't know where you found 1920x1080, but that isn't the max. The INTERNAL display can even support more than that.
The maximum resolution is really hardware based, and since Thunderbolt 2 has a Mini displayport connector (Mini Displayport 1.2), the max resolution for Mini Displayport is 4k (3840x2160).
PLEASE NOTE: Not all adapters can support that resolution, most monitors that can run 4k @60Hz have Displayport 1.2 (The most recent revision), Mini Displayport 1.2, and HDMI 2.0. DVI dual link can run 4k, but only 24-30Hz, depending on the monitor.
Hope this helps!!

Is there a way to access my iTunes Library, which is stored on a (PC) External Hard Drive, on a MacBook Air (through an Apricorn Universal Hard Drive Adapter), without transferring the music files off of the external hard drive?

Is there a way to access my iTunes Library, which is stored on a (PC) External Hard Drive, on a MacBook Air (through an Apricorn Universal Hard Drive Adapter), without transferring the music files off of the external hard drive?
In other words, because the MacBook Air only has 120 gbs of hard drive space & my old hard drive, from a Lenovo, has 500 gbs of hard drive space (and I have over 120 gbs of music), I’m looking to manage my iTunes music from the external hard drive permanently. Upon attempting to access the iTunes library held on the external hard drive the following message comes up: “The iTunes Library.itl file is locked, on a locked disk, or you do not have write permission for this file”. Is there a way to get around this?
Any advice would be greatly appreciated, thanks so much!

You will have to engage a split library which means you will have to start answering questions on this forum because you will need to learn a lot about how iTunes works in order not that have a big mess at the end of it all. It also won't be easy when the time comes to relocate it all to different drives.
You can go to advanced preferences and turn off organize media and copy to items to media folder when adding items to library. Next read about how to selectively consolidate items to the external drive.

"...selected the new tracks directly in iTunes, Control-clicked on the selection, and saw that now you can consolidate selected items." - http://hints.macworld.com/article.php?story=20090919000326840
Remember that when you start iTunes without the external drive turned on iTunes will present you with a bunch of broken links. If you have automatic downloads enabled with iCloud you may have to turn that off to prevent iTunes from repopulating your drive trying to deal with those "missing" tracks.
If you add tracks in bunches to iTunes and want them to go to different media folders you will need to either add them by holding down the option key while dragging if the desired media folder is not the one set in preferences, or by changing the media folder in preferences. Changing media folder preferences only applies to new files added, not old ones.
Okay, I am going to stop typing because you might just reply to me, "Oh, okay, forget it," and I don't need the exercise.

I can't seem to run 3 external displays of off my MacBook Pro 13inc with Retina.

I can't seem to run 3 external displays of off my MacBook Pro 13inc with Retina (2.8GHz Intel Core i7, 16GB 1600 MHz DDR3, 512GB SD driven, OS X 10.9.3) It only picks ups 2 displays. I also have a 15inch Mac Book Pro with Retina that can run all 3 screens. Any suggestions, please?

The late 2013 MacBook Pro Retina 13 inch screen model can power three external displays in addition to its own.
Here is a video showing three external displays working; 1 HDMI, 1 MiniDisplay Port, and 1 thru USB using a Startech external video card to DVI adapter. All the external displays are old 23 inch Apple Cinema Displays hooked up thru each monitor's Apple Display Connector (ADC), then to Apple ADC to DVI adapters, then a third adapter (HDMI, USB, MiniDisplayport). So ADC/ADC to DVI/DVI to whatever/MacBook. The monitors are probably older than some of the users on this board. The USB to DVI external card/adapter is what makes it work, and it's less than $70 online.

How Can I Connect 2 External Display Monitors to a MacBook Pro? Help

I want to know if I can (and How to) connect 2 external display monitors to a MacBook Pro... late 2006 & the new Unibody MBP.
I'll appreciate

Requires additional hardware - the Matrox DualHead2Go. For the late 2006, you'd need the DualHead2Go Digital Edition, and for the unibody you'd need the DualHead2Go DP Edition, with appropriate cabling (and a DVI-to-VGA adapter for the late 2006 MBP).

Yes, having an external HD is necessary for data backups and keeping large media files for packing around etc.
you need data redundancy.

How can I automatically "retract" all windows from my Thunderbolt display back to my MacBook Air when I disconnect the display, esp if the Thunderbolt is the desktop with the white menu bar?

I am in and out of my office with my MacBook Air. I would like to set it up so when I plug in my Thunderbolt display in the office, the Thunderbolt display has my desktop, menu bar and the open windows. If I set the Thunderbolt display to mirror by MacBook Air it adjusts to the lower resolution of the MacBook Air, which is a waste of a cool monitor. I can set it up as an extended desktop and drag the white menu bar to the Thunderbolt display so it displays my desktop but if I then disconnect my MacBook Air, the menu bar is absent and all the windows that were seen on that display are absent, as if it I was still attached to the larger display. The only way around this is to go to Thunderbolt display preferences, drag the white menu bar back to the smaller display and manually drag all windows to the smaller display before disconnecting. Doing this multiple times per day is a real pain. Is there a way to set my MacBook Air to recognize when it is attached to the Thunderbolt display and automatically my desktop and all open windows to it and then do the same process in reverse when I unhook it?

It's definitely not supposed to work like that...when you plug the display in, it should just turn on and adjust your displays. It works like that on my MBP. Kind of a silly question, but do you have the MagSafe from the display plugged in your MBAir too? Thats a requirement. Beyond that, it should "just work."
Not sure if there is some setting to enable...i haven't seen it. Call to support?

How to use an external hard drive on a MacBook Air?

Hi there.
Recently I bought a portable USB external hard drive for my MacBook Air due to my full startup disk. I also bought multiple disks for the hard drive. I inserted the disk, hooked up the USB, and did everything properly. When I first hooked it up, I lost all internet files that I had saved. All images, videos and downloads (such as Minecraft and other gaming downloads) from the internet were gone and unable to find.
Now, I don't want to make the wrong move and lose all of my internet files again, so I am asking how to transfer files SAFELY to the USB without any files being deleted. I tranfered files before, but they were just short cuts to the original file, so I am also asking how to fix that as well. My Dad was a computer technician, although he didn't work for Apple, so he doesn't know how to use the USB.
I've tried everything to find my internet files, but nothing. If there is a way to get them back, I'd be glad if you shared that with me. My dock files aren't working due to this insanely full startup disk, so I'd appreciate it if you could tell me ASAP how to use the USB, how to SAFELY transfer files without them turning into shortcuts, and how to get my internet files back.
Thank you very much.
P.s My OS X version is 10.8.3 (Not with Mountain Lion)

You cannot format a drive so that files will be automatically put on that drive when you run out of room on another drive. Transferring the files must be done specifically by you. You will need to learn how to manage free space on the SSD because 64 GBs is a bit small for much more than OS X.
Drive Partition and Format
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

Switching to the cinema display by closing the macbook air

the nice feature of switching to the cinema display by closing the macbook air and reopening it to use the keyboard with a black (mb air-)screen -e.g.for shortcuts in CS5 or Cad -doesn't work any longer using OS X Lion which is quite annoying. Has anyone found a solution for this problem apart from the 'option with the magnet' ?
this keyboard shortcut puts both displays in hibernation mode
is there a keyboard shortcut which only puts the macbook (air) screen ( under Lion) to sleep ?
if not, this would be a helpful update for everyone using the mac with photoshop or autocad where keyboard shortcuts are constantly needed and handling would be far easier with all windows & task bars on the cinema display only.
Alternatively, has anyone a clue how to put the task bar from the macbook screen to the cinema display ?

I dont know about the putting the screens to sleep, but as far as the task bar goes, when you have both screens running you can go in to display settings and you should see both screens, you can drag the task bar from the air screen to the cinema display.

Random freezing on a Macbook Air?

Hello,
I am encountering random freezing on my Macbook Air, that has started in the last few weeks.
- Applications will suddenly crash at random points
- Sometimes Lion will pop a translucent grey screen asking me to hold down a power button.
- I can no longer relilably install software updates, it often crashes or reports the download corrupted. Sometimes I succeed after 3 or 4 attempts.
- To try and verify it wasn't malware, I checked with Kapersky AV for Mac (it claims it is clean), and I also manually checked for Flashback (I'm not affected)
- Web browser frequently randomly crash, and I can't run anything that involves 3D graphics
- it still happens even if I disable startup apps
- Sometimes I get the forever beachball and the top bar becomes corrupt or blank
- There is no pattern to this, except some apps seem to crash more often than others
It feels like a "hardware" issue, due to its intermittency/unpredictability/non-repeatability.
I am wondering if either my RAM or CPU is defective? Or is this something software?
It is a 2010 Macbook Air 11.6", a little more than a year old.   What are my recourse that would result in minimum wasted time:
Sometimes it goes for an hour with no problems (I can even run 3D) and might not be able to demonstrate in front of Apple.
Unfortunately, I did not have the foresight to get AppleCare, so I'll have to expend some time and/or money.
What is least painful?
I first backup my personal files (mostly done, as it's mostly on various cloud services)
1. Assume it's software: Attempt to reinstall OSX, cross fingers it doesn't happen again?    Run a few overnight 3D benchmark tests to 'burn it in' and verify it is not a hardware problem?
2. or Purchase a new Macbook Air & then bring the old Air in, then resell the Air after it's repaired? (Minimum downtime method, high cost method)
3. or Apple Store & try to get it repaired/serviced.   (Lower cost method)
4. or trade it in for a discounted refurbished 2011 Air?   (If the Apple Store does this sort of stuff)
Thanks,
Mark Rejhon

I am able to drag photos from iPhoto to Contacts on my MacBook Air. I resize the iPhoto window to make it smaller, open Contacts, select the Contact in question and click the Edit button at the lower right of the contact. I then drag the photo from iPhoto.
The step that I'm guessing that you might be missing is clicking the Edit button at the lower right of the contact.

External display turns off when macbook isn't charging...

I have my old 2007 white Macbook hooked up to an external display. Recently I have been wanting to calibrate the battery while using it on the external display, but every time I remove the charger from the Macbook the external display will stay on for a couple of seconds then turn off, it will only come back on when I click the mouse or press something on the keyboard, but then it will go back to sleep. Note: when my Macbook is connected to the external display I keep the screen closed.

When you are looking at the displays in the System Prefs, all you have to do is click and drag the tiny rectangular bar from the main screen to the external monitor screen (this designates the primary monitor).
Once you've done that, all you have to do is close the lid. Your screen will flash a couple times, but the external monitor will then remain on and working, and you dont need to keep your lid open.
FYI, I would turn down the brightness of your MBP down all the way (for both the screen and keyboard). I have found that this reduces any heat build up that it may have from running with a closed lid.
Hope this helps!

Is it okay to charge macbook air while playing a game and it is hot?

I use my macbook air for aging. Is it okay to charge it while I'm playing a game. It was really hot when I was charging it. Will it affect it any?

It is all right to charge your MBA any time you are using it, hot or not. See these authoritative article regarding Apple batteries for additional guidance:

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...

External Display and AC charger (together ) Causes 70% CPU usage :(

Ok, here is what I have :
- MacBook Pro 13" early 2011
- Mac OS X Lion 10.7.3
- External Display ( Samsung SyncMaster 2333)
- MiniDisplay port to VGA adapter.
Here is my problem :
When I'm using my computer normally with AC charger plugged in everything is normal, once I plugin the external monitor, a process called LoginWindow takes up to 70% of my cpu and the cooling fan goes noisy.. If I unplug the AC power, everything is back to normal, and the external monitor keeps working normally, AC back -> 70% cpu is back, if unplug the monitor, everything goes back to normal again, In conclusion, external monitor and AC power doesn't work together...
PLEASE IS THERE A FIX FOR THIS ?
thanks for reading.

Hey I figured something out with "insomniaT" ( a prefPane that prevents macbook pro from going to sleep when closing the lid ) ... I don't know why this worked but it did
here is the steps :
- while the power cord is unplugged and external monitor plugged in,I activate insomniaT
- then I closed the lid of my macbook pro and plugged the power cord, and then I woke up the MBP with an external usb keyboard...
--> the Samsung monitor woke up and worked normally, LoginWindow process works fine ( 0.1 to 0.4% of cpu )
IT WAS ALL LUCK, have no idea how this worked ...
thanks.
