Macbook Air (2010), Bluetooth 4.0?

I have a Macbook Air (2010) and upgraded to Lion OSX. I was checking my Bluetooth version and it lists it as 4.0 - more specifically: 4.0.1f4
Is this possible that my Macbook Air Second edition got an upgraded Bluetooth in the Lion Operating system?
Is this the same Bluetooth 4.0 as the iPhone 4s?
So many questions Appreciate any respeonses to the above!
Thanks!

That refers to the software release version. Everyone has the same software version under Lion.
Bluetooth 4 hardware was added beginning with the Mid 2011 model.

MacBook Air 2010 Very Slow (even after clean reinstall)

Hi,
Problem
The performance of my Macbook Air 2010 has slowed to the point where I can hardly complete basic tasks. For comparison, I use a MacBook Air 2013 at work and do not experience the same performance issues, so I believe my expectations are not unreasonably high.
My Question
Can you please advise on what I can do to troubleshoot? I've tried the solutions listed below, all of which have failed.
I'm grateful for any help you can offer.
Problem Description
Switching contexts or tabs, operating within applications (such as Chrome, small Excel spreadsheets, navigating files), and browsing the Internet has become a slow, laggy and crash-filled experience.
When right-clicking an icon and selecting 'Open With', Finder frequently times out or requires time to populate a list of applications.
Machine is slow to the point where, unless a solution presents itself, I'll have to get a new MacBook Air.
What I've Tried
'Religiously' close all applications after use; extremely conscientious of number of applications running and their resource requirements.
Clean reinstall of OS X.
Storing all media on external hard drive to create more storage space.
Clearing cache for all browsers regularly
Always running machine on battery power
Regular reboots
Machine Specs:
MacBook Air 13-inch, Late 2010
OS X Yosemite Version 10.10.2
Processor: 2.13 GHz Intel Core 2 Duo
Memory: 4GB 1067 MHz DDR3
Graphics: NVIDIA GeForce 320M 256 MB
Storage: 87GB free of 250GB

Thanks, dominic23.
Unfortunately, it did not work.
-Tried starting in safe mode, resetting SMC, and repairing disk. Resetting the SMC helped upon reboot, but performance degraded swiftly and back at a low within 30-minutes.

I can't connect my iphone5 to my Macbook Air via Bluetooth?

Can someone please tell me why I can't connect my iphone5 to my Macbook Air via Bluetooth?
Is this just the most ridiculous oversight or is there some underlying reason why this doesn't connect and function properly? How amazing would it be if I could just click on a contact number and dial from my phone like I could in 2008 via my Lenovo and my Blackberry. This blows my mind that two devices that scream compatibility are far from it. From my bluetooth options it see my device, then sends a code, I confirm and then it briefly connects only to disconnect almost immediately. #fail #appleoversight #failfailfail
Fix it or I'm going back to PC ****

Do all your cases and screen covers for MacBook air 2010-2011 fit the 2012 model

Do all your cases and screen covers for MacBook air 2010-2011 fit the 2012 model

Upon receiving my 2012 MBA, I removed the inCase hard shell from my 2011 model and fitted it to my 2012 unit. The fit is identical. Dimensionally they are the same.
So, if you are asking do all of mine fit? Yes they do.

Can't pair iPhone 5 to MacBook Air by Bluetooth

I have a MacBook Air 2010 I want to reset but don't have USB how can I do this

I Just purchased a MacBook Air 2010 but it did not come with USB drive to reset it can I do it without or where can I get one? It has10.6.8 on it Mac OS X it has old owners stuff on it.

From what little you say, it sounds like the computer's hard drive was partitioned as Master Boot Record and then formatted FAT or NTSF. You'll need to run Disk Utility and delete the partition and then click on the Option's button and select GUID. Then you'll be able to format the drive as HFS+ to install OS X.

HT204387 I want to transfer from my Macbook Air using bluetooth.

I have been trying to transfer music from my Macbook Air using bluetooth to my Iphone 4s OS 6.01. Each time I try I get the message 'the device doesn't have the necesary services". I also noticed that my old 3GS is not visible and my old Nokia 95 can't pair with my 4s.
Any ideas?

You don't. iOS doesn't support file transfer over BT.

Seems my macbook air's bluetooth cannot sustain pairing with other devices. It shuts off right away. Been trying to pair my iPhone 6 with it but it keeps disconnecting. I can't use my airdrop. My air is a 2011 11 inch with serial number

My Macbook air's bluetooth does not sustain paring with my iPhone 6 so I cannot use my airdrop. Is there something wrong with my mac's bluetooth or is there something I need to do to activate it? My iPhone's control center has its airdrop open on everyone and with bluetooth open.
<Personal Information Removed by Host>

Both devices need to have their Bluetooth on, but they need not (and indeed cannot) pair.
A MacBook Air can communicate to an iPhone using AirDrop. Both devices would have Bluetooth on without pairing as I described. But actually if you have a mid-2011 MacBook Air, that computer is too old to communicate that way, so you are out of luck.

Having trouble with connecting my iphone and macbook air using bluetooth for internet tethering

Hi,
I am facing an issue connecting my iPhone5 to my Macbook Air using bluetooth primarily for internet tethering - personal hotspot.
Every time I try to pair my iPhone with the Macbook Air, I get the error on the iPhone that 'the device that I am trying to connect is not supported'.
Can anyone provide assistance to me on resolving this issue.
Thankyou,
Ashwani

You can't resolve it using bluetooth because it is not a feature you can use here are the supported files for bluetooth http://support.apple.com/kb/ht3647
YOu will have to contact your carrier and enable personal hotspot as suggested by questionaire.

Error message as above and below:

Wipe macbook air 2010 to sell.

I am selling my daughter's MacBook Air 2010 and need to wipe it clean, de-identify it, or whatever needs to be done. I have another MS Office license I can reload on it afterwards, but I no longer have the any of the start up software/usb/manual etc. How do I do this, and will the operating system be lost?

Before you sell or give away your computer, in addition to the steps mentioned in this support article, take these steps:
1. Run Apple Diagnostics or the Apple Hardware Test. The buyer will do this (or he should), and you don't want to be surprised by the results.
2. Reset the PRAM and the SMC, which might contain personal information.
3. If you set a firmware password, remove it by running Firmware Password Utility in Recovery mode.
4. If you activated FileVault in OS X 10.7 or later, turn it off.
5. If you use Boot Camp, the partition must be deleted.
6. If you created any other data partitions on the internal drive, remove them in Disk Utility.
7. If the machine has an internal hard drive, erase the one remaining data partition with the option to zero out data. An SSD doesn't need to be zeroed.
You can't legally or practically transfer any software downloaded from the Mac App Store to the new owner of the machine, even if it was free. That includes OS X, so if you upgraded to OS X 10.7 or later, you must reinstall an older OS, either from the installation media, if applicable, or by starting up in Internet Recovery mode (option-command-R at the startup chime.) If you installed from physical media, deliver those to the new owner.
If you're selling the machine, or donating it in working order, and it originally shipped with OS X 10.4 or 10.5, then you have the option of installing either from the discs that came with it or from a retail Snow Leopard disc (which you must then transfer to the buyer.) The buyer should understand that if he doesn't get the original discs from you, he won't get the bundled iLife applications or the Apple Hardware Test. Replacements for the original discs can be ordered from Apple.
The new owner will have to redownload any software that came from the App Store, including OS X upgrades, under his or her Apple ID. If you ever updated the bundled iLife applications (Garage Band, iMovie, and iPhoto) through the App Store, you can't transfer those either. The buyer will have to purchase them.
Remove the machine from your list of registered products. If it's still covered by an AppleCare Protection Plan, transfer the coverage to the new owner by following the instructions in the AppleCare Terms and Conditions (under the heading "Transfer of Plan.")

How do I pair my macbook air 2010 with apple tv 2

-

Sorry, that is not possible.
As you can see here, that MacBook Air is too old to use AirPlay Mirroring:
About AirPlay Mirroring in OS X - Apple Support
You also cannot use an HDMI cable to "pair" your MacBook Air. The reason is your model has a mini-display port (that looks like a Thunderbolt port, but is not). Therefore, it cannot send audio to the Apple TV.
