How do I connect MIDI to MacBook Air

Having installed Hauptwerk virtual organ, I want to configure connection from MacBook Air to Johannus Organ (uses RCA plugs). How do I connect Air to organ?

Search for a MIDI to USB interface. Here is one possibility: http://www.amazon.com/CREATIVE-EMU-XMIDI-MIDI-Interface/dp/B000JLU26W/ref=sr_1_1 ?s=musical-instruments&ie=UTF8&qid=1400182349&sr=1-1

How should i connect my new macbook air to lcd projector for presentations?

how should i connect my new macbook air to lcd projector for presentations?

One of these should work, depending on the projector. Just note both will not allow you to play protected movies on the projector.

How do you connect iTunes on Macbook air to bluetooth?, how do you connect iTunes on Macbook air to bluetooth?

I have a new Macbook Air. How do I join iTunes to my bluetooth on my soundbar?

The Air has mini-Displayport video out, so depending what ports the monitors have (mini-displayport? DVI? VGA? HDMI?) you will need the appropriate adaptor (eg, miniDP to HDMI) and probably also a cable (eg a standard HDMI or DVI cable).
You can get most of the adaptors/cables from Apple here:

but can usually find them cheaper online elsewhere.
Edit: the only way, I believe, that you could attach two monitors to the Air would be to use a USB adaptor for the second monitor. Something like this:

How do I connect ethernet to macbook air

I have purcahsed an authorized usb adapter for ethernet for my macbook air. I have made several attempts using several suggestions from the web, no luck. Any links you could share or advice would be most appreciated.
Thanks, mg

The original poster said he "purchased an authorized USB adapter for ethernet ...". I assume he (and therefore we) are talking about Apple's USB Ethernet Adaptor cable or equivalent:
http://store.apple.com/us/product/MC704ZM/A/apple-usb-ethernet-adaptor
Does his "authorized USB adapter" have the right drivers? I don't know, but I trusted his use of "authorized".
So my guess is you're saying the Apple adapter would work, but if the adapter the original poster had is not really authorized as an Apple product substitute, it may well not work.

How can I connect my new MacBook Air to a LaCie hard disk with TIme Capsule backup from my old Imac? LaCie has USB 2.0, FireWire and eSata ports.

You can direct connect your MBA to the LaCie via USB 2 cable. If you have an Apple Airport Router you can USB connect the LaCie drive to the router and then use Airport Utility to configure it. Time Machine can access it either way.

I think the McAfee suite will do the trick when I pay them a one-time fee of $69 or $179 for a year for unlimited support.
Your call of course but IMO a waste of money. Please read this first:
There are many forms of ‘Malware’ that can affect a computer system, of which ‘a virus’ is but one type, ‘trojans’ another. Using the strict definition of a computer virus, no viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions. The same is not true of other forms of malware, such as Trojans. Whilst it is a fairly safe bet that your Mac has NOT been infected by a virus, it may have another security-related problem, but more likely a technical problem unrelated to any malware threat.
You may find this User Tip on Viruses, Trojan Detection and Removal, as well as general Internet Security and Privacy, useful:

How to turn off screen on Macbook Air when connected to Led monitor screen?

The only way you can turn it off is to close the lid - so you would need an external wired or wireless keyboard and mouse/trackpad attached.

How to charge mid 2011 macbook air battery using Thunderbolt display

While trying to organize all my computer miscellaneous (cords, adapters & so on), I came across an adapter on a little card with the comment, "For use with your Thunderbolt Display and Mac with MagSafe 2 port." Appears to be for charging my mid 2011 MacBook Air via the Thunderbolt Display -- what might be the advantages/disadvantages in doing so? I found the info. in the product manuals to be pretty skimpy about this.
Thanks,
Linda

So, I guess the adapter came with the display just in case I had a compatible Mac. I should have noted that on the card. Now, about the rest of the stuff in my Apple mystery box...that's for another day.
Thanks, seb101, for your quick reply!

My mid 2011 MacBook Air fell off my couch onto carpet. Slowed down.

I made a post a few weeks ago about how my mid 2011 MacBook Air slowed down randomly over night. A few days later it randomly started functioning properly again. I was stoked.
Today, I was using my MacBook on the couch, when it slipped off and landed on the carpet bottom up with the lid closed.
The moment I opened it up again, it was back to being slow again.
I ran the Disk Utility, tried repairing it, it said that the hard drive 'appeared to be ok'
But yeah. I'm gonna say it's a pretty safe to assume that the drop has everything to do with the slow response time.
Would anyone happen to know what actually might have went wrong, though?

I would think a poor connection of some sort, may be a plug and socket or a soldered joint problem. I think you need to take it in for repair, I cannot think it will be software that is causing the fault, but...... you never know.

No AirPlay icon on mid 2011 macbook air with a new Apple TV

Hi. I just bought a brand new Apple TV. I own a mid 2011 macbook air on which I've installed mountain lion OS X. both the apple TV and my macbook air are connected to the same wireless network, yet i dont have the AirPlay icon on my macbook. I'm able to play music from my mac's iTunes library, and even tough the homesharing on iTunes is on, I dont have the airplay icon so I can't stream movies\videos\pictures which are not in my iTunes library.

About AirPlay and Airplay Mirroring
AirPlay Mirroring requires a second-generation Apple TV or later, and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer). For non-qualifying Macs you can try using Air Parrot.

Mid 2013 macbook air: battery drain / running hot

Hi there,
For the last couple weeks my MBA starts to run hot and drain battery fast if I've been using it for a few hours.
I use it a lot on most days and connect to powercord only once it drops down low, like below 20%.
Have just seen other posts who recommend doing that at 50% battery and will now do the same.
However my question is: have i ruined my battery in the meantime?
AND/OR is there something else i can do to get battery running like it used to, and stop the loud fan switching on all the time because it's all running too hot?
I've copied in an etrecheck in case that helps diagnose more....
thanks heaps for any help!

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a few minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.
