How to unlock MacBook Air that was purchased used

I just purchased a MacBook Air from RAC. I opened it and the previous user, or a employee at RAC hadn't closed things down. As I was closing things getting ready to try and reset it. The computer returned to the log in page. Now the computer is locked and I have no idea what to do. I am not wanting to reset completely to factory settings because the previous owner put a very expensive program on it that I would like to keep.
I have no idea what year it is or any other info like operating system

Has the previous owner relinquished registration of the Air to him/her?
You should be able to register the device at that time with YOUR apple ID, thus satisfying the system's request for a valid Apple ID that owns the resident copy of Mountain Lion (if the system came with it).
The old user can go on Apple's website to edit your Support Profile to delete ownership registration of the product(s).
The new user, you, then simply registers your "new" device, also online. Once the old owner has deleted ownership, the serial number is freed for a user (new owner) to add it. The new owner should have an Apple ID first, which I imagine you do, since you login here with that ID.

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.

Your Solid State Drive and having enough space inside your Macbook Air & Pro
Solid State Drive usage premise, or the “more space / upgrade SSD” question
There have been questions posed and positions taken by many people who are trying to use their Macbook Air or Pro’s solid state drive (SSD) as a mass media storage device, for either pictures, videos, massive music collections or all three combined; but this should not be the working premise of a ‘limited’ SSD and its use.
In which, it’s the case of those users with either 128GB, 256GB, or even 512GB of internal SSD space, that have or are running “out of space”, that questions are raised. The immediate premise of some users can sometimes be “(how to / if) upgrading my SSD” when in fact in nearly all instances another approach is the logical and sensible one that needs to be looked into and exercised.
Any Macbook containing a SSD should be idealized as a ‘working platform’ notebook containing all your applications, documents, and weekly or bi-weekly necessary files. All collections of media files such as pictures, music, and videos, unless directly needed should be kept off the notebook and on an external hard drive or likewise. While the ‘working platform’ premise is also the case with larger internal conventional hard drives of 1TB+, its implementation isn't as critical except in terms of data protection.
Realistically, you should at most coordinate roughly 20 to 25% of your total SSD space to all audio-video personal use media (picture / music / video collections), leaving the remaining amount on an external HD.
Nobody should consider any notebook a data storage device at any time under any circumstance, rather a data creation, sending, and manipulation device; and in the case of a SSD, this is more important for purposes of having sufficient working space on the SSD and reducing SSD ‘bloat’ in which cases someone is wrongly attempting to use the SSD space as a large media storage nexus.
The rare exception to the collective usage and premise of SSD use in which a much larger SSD is truly needed are for those in video and photography professions that require both the extremely fast speeds of the SSD and the onboard storage for large and or many video and photography files. However this also falls under the premise of a ‘working platform’ for such peoples rather than the intent of many who are using the SSD as passive and static data storage for media files very infrequently needed or accessed.
All on-notebook data collections should be logically approached as to necessity, and evaluated as to whether it is active or passive data that likely doesn’t need to be on the notebook, allocations of space-percentages to as-needed work and use, apportioning space for your entertainment media, and questioning whether it should it be on the notebook for more than short-term consumption.
Considerations should be made in the mind of any user in differentiating the necessary system data (System hub) comprising the Mac OSX, applications, necessary documents that both must and should be on your internal SSD, and that of the users personal data (Data hub) comprising created files, pictures, music, videos, PDF files, data created or being created and otherwise, that likely unless being used soon or often should be parked on an external hard drive for consumption, or temporarily loading onto the internal SSD.
You both can and should purchase whichever SSD size you need or see fit, but even in the case of the largest of SSD, unless use-considerations are made, and SSD spaces are allocated as should be the case indicated above, one can easily and immediately run into this quandary of “needing more internal SSD space”, in which instance a different approach in usage must then be implemented.
However it is almost always the case, that such large media files are wanted to be stored internally rather than actually needed, in which case the external HD is both prudent as well as necessary. Additionally costs per MB are infinitely less on an external HD than an internal SSD in any consideration of data expansion needs.
A Professional Example
In the case of a Macbook Air or Macbook Pro Retina with ‘limited’ storage on the SSD, this distinction becomes more important in that in an ever rapidly increasing file-size world, you keep vital large media files, pics, video, PDF collections, music off your SSD and archived on external storage, for sake of the necessary room for your system to have free space to operate, store future applications and general workspace.
You should also never be put in the position of considering “deleting things” on your Macbook SSD in order to ‘make space’. This is especially what your external HD is for.
Professionals who create and import very large amounts of data have almost no change in the available space on their notebooks internal SSD because they are constantly archiving data to arrays of external or networked HD.
Or in the case of the consumer this means you keep folders for large imported or created data and you ritually offload and archive this data for safekeeping, not only to safeguard the data in case your Macbook has a SSD crash, or gets stolen, but importantly in keeping the ‘breathing room’ open for your notebook to operate, expand, create files, add applications, for your APPS to create temp files, and for general operation.
Slim USB3 1TB external hard drive
External Hard Drives
External hard drives are both extremely cheap and regardless of the size of your internal SSD (or even internal hard drive if the case), you need an external hard drive with your SSD equipped Macbook for several reasons:
1. Data backup and protection.
2. Redundancy for important data.
3. Necessitated ideal space for large media files for collections of pictures, videos, and music etc.
While ever changing in price, typical portable 2.5” external hard drives in USB3 run roughly $65 for 1TB or $120 for 2TB small portable USB3 hard drives. Such drives range in thickness between 5mm and 15mm, with recent improvements in storage of 500GB drives in 5mm profiles.
There is almost no premise in which a small 12mm thick 1 Terabyte USB hard drive cannot be taken along with any Macbook as an external large storage extension inside any Macbook carry case or pouch. Typically such external HD profiles are not much bigger than a deck of cards.
External hard drives are a foregone necessity for purchase with any Macbook for at the very least Time Machine backups, data redundancies, and ideally for large media storage.

The kernel is using excessive processor cycles. Below are some possible causes for the condition.
Throttling
When it gets high temperature readings from the hardware, or low voltage readings from the battery of a MacBook, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to:
☞ a buildup of dust on the logic board
☞ high ambient temperature
☞ a worn-out or faulty battery in a portable
☞ the malfunction of a cooling fan, a temperature sensor, a voltage sensor, or some other internal component
Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.
If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on AC power, charging is causing the machine to heat up. That behavior may be normal for some models. CPU usage should drop when charging is complete.
Apple Diagnostics or the Apple Hardware Test, though not very reliable, is sometimes able to detect a fault. For more thorough hardware testing, make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
If nothing is wrong with the hardware, then whatever you can do to improve cooling may help.
Installed software
User-installed software that includes a device driver or other kernel code may thrash the kernel. That category includes virtualization software, such as Parallels and VMware, as well as most commercial "anti-virus" products. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or starting in safe mode. Note, however, that disabling a system modification without removing it or testing in safe mode may not be as easy as you think.
Corrupt NVRAM or SMC data
Sometimes the problem is cleared up by resetting the NVRAM or the SMC.
External display
Connecting an external LCD display to some MacBook Pro models while the lid is open may cause this issue. If applicable, test by closing the lid or disconnecting the display. You might get better results with a newer LED display.

How long should macbook air battery should last

how long hours does macbook air 2011 13 inch baterry

No, that's not good at all. Its battery probably needs to be replaced. Have Apple evaluate it for replacement. The 60W power adapter is fine.
so the condtion of my notebook is pre used
I am not certain what you mean by that, but if you did not buy your MBA new from Apple, replacing its battery is even more justified. No one knows what its previous owner did with it.
If its battery was permitted to remain completely discharged for a long time (more than a few days) or if it was hardly used at all, for instance if it was always connected to power and has very few charge cycles, or if it was subjected to elevated temperatures for even a brief period of time, it almost certainly requires replacement.
A well-maintained battery in a MBA of that age will have had very approximately 300 to 800 charge cycles. I usually charge that MBA two or three times a week. Check its condition by clicking the  (Apple menu) > About This Mac > System Report > Power.
$129 US includes replacement and a warranty.

Anyone know how to determine Macbook Air screen tech? Causing migraines

Hi There,
Last year, I expereinced a lot of mild migraines which I've traced back to a new Macbook Air.
At first I had no idea of the cause (diet, stress etc) but have noticed that my eyes feel uncomfortable looking at the screen of my Macbook Air (I don't have this issue with my Dell monitor).
My eyes don't hurt per se, but I can detect a sublte jittering with the screen - which can turn into a migraine.
After doing a bit of research, it seems like most (but not all) LCD and LED LCD displays use something called pulse-width modulation to control brightness but after calling Apple support, they told me my MBA doesn't use this technology.
Does anyone know how to determine the underlaying technology in Apple displays so I can research the cauase of my headaches? I found a good Ukranian website (in english) that explained pulse-width modulation but it didn't really talk about other technologies.
Any pointers in the right direction would be much appreciated.
Cheers
Ben

2013 Macbook Air system freezes

A couple times a day, my MacBook Air 13" Haswell will freeze and I have to do a hard reset to get it back. It usually starts with the applications freezing, but i can still use the keyboard/mouse and can still switch between apps but none of them respond. Then the finder will lock up, and finally the mouse/keyboard stop working and I have to do the reset. My co-worker has exact same model and is experiencing same issue. I have read other threads about black screens, but that never happens to us.
This occurs in any configuration, whether I have any USB items in or not, whe

This is a rather old thread so I hope aapotts as found a satisfactory fix by now.
There are a lot of possible causes/solutions to the wireless/Internet freezing phenomena
There doesn't, at this time, appear to be one universal cause, nor one sure fire cure.
Some of this has been traced back to faulty hardware, but some have found the problem has nothing to do with their machine but instead to do with using old wireless routers and their settings/updates.
Bluetooth, or other wireless signals interference, corrupt network settings all have been identified as culprits and cures found
Some have had this problem on old Operating Systems... some first discovered it only when they migrated to Mavericks.
Some have brand new machines that work fine, other have a problem, returned their machine for a replacement (under the USA 100% satisfaction warranty) and report no more problems.
As you can see it's hard to pin down, and that's what makes it hard to find a "cure'.

How do I connect my Macbook Air to tv via Apple TV and airplay ?

Hello wayneharlow
You should see an AirPlay button in the Menu Bar in the upper right hand corner near the Date and Time. If you do not see it, then you may need to turn it on to show up there, then it is a matter of selecting the Apple TV from that drop down menu. Check out the article below for more information and troubleshooting if needed.

How to use macbook air as ereader

I'm interested in a new Macbook Air. I'd like to know how to use it as an ereader.

I would use the Kindle app for Mac. If you use iBooks on an iPad or iPhone, this is not a good solution but until Apple provides iBooks for Mac, there is no good solution.
There may be a way to download an iBook, convert it to PDF and upload it to the Mac, it sounds complicated.
