Macbook Air is locked. What command should I use to reboot? Why is this happening? Pics included

I recently got a MacBook Air from someone who owed me money. The MacBook Air is completely locked and Im not sure how to bypass the secured login screen or which code to use that will boot in an alternative mode. I've tried Command + R, Command + S, Option and none of these three worked. When I press Command + R, I get the following lock screen (the picture is just upside down, not sure why.)
I own a macbook pro and have reset my password using Command+R. Not sure if MacBook Airs need a different command. When I press Command+S I get a loading screen, then a screen that tells me "Your computer is disabled. Try Again in 60 minutes"
Why is this happening?
What command can I press to bypass this?
Could I put a clean OS on a USB drive and install it that way to have a clean install? If so, how do I boot it, if I can only get to these screens?
Now that my computer is disabled and I have to wait 60 minutes, should I perform the correct command once the time is expired or can I use it immediately, while the disabled time is still active?
Please help!!!!
Also, not sure which OS its running since I can't get pass this to fully inspect the Macbook Air.

That is an EFI Firmware Password.
There are only two ways around it: bring it and some money to Apple, who will certainly want proof of ownership, or obtain the password from its previous owner.
A third method that I do not recommend is to pay any number of sketchy third party outfits that allege a means of removing the password. There are several reasons I do not recommend it, among them: I have no personal experience with them, I have no idea if they will be successful, and you may have no recourse if they damage the Mac and render it permanently broken. Apple will certainly refuse service if anyone other than Apple or an authorized Apple repair facility tampers with it.

I am not really interested in what a json file is I simply want to get rid of this pop up box.

What is the Pin Code for unlock for Macbook Air System Lock ?

What is the Pin Code for unlock for Macbook Air System Lock ?

It usually means that the owner of the device sent a directive through icloud(find my mac), to lock the device because it has been stolen.
The only means to unlock the device is to have Apple (Apple Store) unlock it for the owner. If you are the owner, be prepared to show proof of legitimate ownership. It is likely that Apple will want to contact the registered owner to make sure that the device has been legitmately transferred.
I'm really thinking you may have bought stolen property. Ask the seller why it is locked, and if the device is registered to him/her, to release the registration on Apple's website. Only then, will you be able to re-register the device in YOUR name.

I have a macbook air and need additional storage should i consider a time capsule or a simple external hard drive?

I have a macbook air and need additional storage should i consider a time capsule or a simple external hard drive?

If you move live files (files you don't want to lose) to an external drive, you need to back them up. Any files not backed up are at risk of loss. Hard drives and SSDs can fail at any time. It is hard to backup a Time Capsule so a TC should be used only as a backup device.
Do you have a Time Machine backup now? If so, and if it is large enough, you can backup your internal and external disk to it using Time Machine. If not, you all need to purchase an external drive or TC as your backup device. (I recommend an external hard drive for backup instead of a TC.) Ideally the backup drive should be twice the size of what you are backing up but 50% larger will work so if you have an external 1 TB disk and an internal 250 GB SSD then a 2 TB backup disk will work well.
By default, Time Machine will not backup the external disk. You need to remove it from the exclusions list:
To have Time Machine backup your system disk and your external offload disk up onto your Time Machine disk:
 > System Preferences > Time Machine > Options… > Remove the offload HD name from the exclusions list.

Hi
I have a Macbook air & iPhone 4.
what do I need to do if I want to buy a book (ebook) or an application that is not available in the iTunes store in my area i.e. Africa (Egypt)?
Do I need to open a different account in the iTunes store in the other area i.e. USA ?
Please advice
Thank you

You can only buy content from your own country's store i.e. the Egyptian store if you are in Egypt - you need to be in a country to use its store, so to use the US store you will need to be in the US and have a US billing address on your account. If there is an app or any other item that you would like to be buy that isn't currently available in the Egyptian store then you can try requesting that it be added, but unless the app's developer or rights-holder agrees to it then Apple won't be able to sell it there : http://www.apple.com/feedback/itunes.html

If nothing else works, you might try this one. It has worked for many others ...
Use iTunes to do a reset to factory default condition. Always be sure to do your backups before fiddling with your iPad. You might do both the iCloud and the iTunes backup, just to be sure!

Re: IPAD2 very slow after IOS 8 upgradein response to pacoKAS
SOLVED: IOS 8 Issues on iPad 2:
I just returned home from a visit to the Genius Bar. Like you and many others, when I upgraded my iPad 2 to IOS 8, it became practically unusable. It was VERY slow, lagged whenever trying to to do anything. Lots of screen freezes and apps spontaneously crashing. I was convinced that the processor on the iPad 2 just couldn't handle the new IOS and I went in to see about restoring to IOS 7.
Thankfully, I was hooked up with a very sharp guy at the bar. The problem is not with the OS, it is with it being an *upgraded* OS. He used the analogy of when you had an older Windows computer and how over time (and over upgrades), they just tended to get slower and slower because of all of the garbage that was carried forward in the upgrades. At those times (and if you've ever had a Windows computer, you get this), the only thing that would speed it up would be to wipe the machine and do a fresh install of the current OS and then reload your apps, and the viola, everything would be fast again. Well, it turns out that IOS can suffer the same problems.
THE FIX: FIRST, be sure you have a current iCloud backup of your device. Connect your iPad to a computer that has a clean fresh copy of IOS 8 on iTunes (this is best done with a computer other than the one that you sync your device to because you DO NOT want to restore it from a back up just yet). Ideally, if you do this at an Apple store you'll be assured of the right version there and someone to answer any questions you might have along the way. You then hold the power and home button down to hard-reset the device and continue to hold them down until it reboots into recovery mode. You then follow the instructions on the computer to reinstall the OS on the device (which wipes everything from it and then reinstalls a clean copy of it). Once this is done (which only takes about 15 minutes), your device will reboot and ask you to set it up. Answer the questions about language, location, etc. and continue until it asks you to log into your iTunes account. Once you do that, it will ask if you want to either 1) Set it up as a new device, 2) Restore from iCloud, or 3) Restore from iTunes. Choose (2), restore from iCloud. This will ensure that it brings down "clean" copies of all of your apps and preferences rather than the potentially corrupted ones that might reside in your iTunes backup. That's it! It will take a few hours depending on how much data and apps you have, but I am happy to report that my iPad 2 is now running IOS 8 and it's running as fast as it ever did when it was brand new!
To sum it up, this process 1) Wipes your device and the garbage causing your problems, 2) Loads a clean and bug-free version of IOS 8 to your device, and 3) restores your apps and data so that it looks just like it did before the wipe, with the exception that it works now! :-)
Note also that by following this process you don't have to go through the painful and laborious process of reloading all of your apps, data and/or settings. iCloud takes care of all of that for you.

What cable should be used to connect a macbook pro, 13 inch, early 2011 model to an external projector so the project displays the image on the computer screen?

You will need a cable or adapter with a minidisplay connection for the MBP. That will be inserted in the Thunderbolt port. The other end is dependent upon the connections of the projector which you have not listed.

I advise to reply to the one you want to reply to.
You have had good information here. I will not repeat that here.
I would like to add:
you have incompatible software: start in SafeMode, read Woodmeister and see if it is free of issues.
Akamai is crap software needed or not, Huawei the same.
It is very possible that the keygenerator you used for generating a key for some softwares has infected your mac.
The non-regular software with the false key(s) are not compatible probably or generate malware. Luckily you can not update them automatically because the keygenerator blocked the software for contacting the developer... I propose to consider getting rid of those softwares by really good uninstalling.
You have a beautiful mac, don't degenerate it with crapped software. There are alternatives for expensive software, for example Adobe Photoshop has a free alternative (with a less beautiful interface) in GIMP. And so on.

I have a MacBook Air and for what ever reason, the print settings have gone out of whack. I am not sure how to set to print a normal A4 paper size or a standard envelope. These settings were working O.K., but not now

I have a MacBook Air and for what ever reason the print settings for envelopes and normal A4 paper size changed from printing correctly each time I wished to print. Now, each time I wish to print either, I have to rest paper size and or Envelope vertical or horizontal. Can anyone assist with how to reset in order to print correctly without the need to rest each time please?

Log in to the Developer forum. You will find instructions on how to install the lastest beta. Your problem is the beta you have installed has expired. All of them did on October 5; you will find hundreds of threads discussing this. If you have a beta it is assumed that you will continue as a beta tester, so a simple update using iTunes will not work.
If you no longer want to be a beta tester install the GM 7.0.2 by restoring from iTunes using DFU mode.

It depends on which model you have:
13" - 1440x900
11" - 1366x768
This of course assumes you are talking about your internal display.

I find the iphone 5s photographs and videos very difficult to copy into my PC after upgrade to ios 7.1.2. Previously I was able to open it in my computer (Windows 8.1 loaded on macbook air 13" July 2013) model, within iphone ikon - DCIM. Why not now

After upgrade of my iphone 5s to ios 7.1.2, I am not able to open iphone ikon- Internal Storage-DCIM - in My computer
The folder is shown as empty
I use Window 8.1 loaded on my Macbook air 13" July 2013 model
Should I stop using iphone for photography and use my Canon DSLR
Taking photo is easy with iphone 5s. But retreiving the photo/video
is time consuming and I feel is a waste of time
Any way out?

Is your phone unlocked when your importing the pictures.
This sound more like a window 8 issue.
