Trim function in osx lion for Macbook Air

When does SSD trimming start? Can it be manually forced?

You do not need to force TRIM. I guarantee you that the SSD knows far better than you how to manage wear leveling.
Not so that is why they created TRIM. If the drive knew better then TRIM would not be needed.

TS3926 Installing OSX Lion on MacBook Air

I have a MacBook Air with solid state hard drive. The Disk Utility partition tool shows that "This partition cannot be modified". What can I do?

rockville wrote:
When I started the downloaded Lion file, it asked me "What hard drive do you want to install Lion on?". There is only one drive, but I cannot select it, (it was greyed out) because of his disk cannot be used to start up your computer". I did the exact same on my desktop machine with no problem. Thanks
Rock,
If you have a spare USB flash drive around you can make a copy of the Lion install on your desktop machine and use it to boot your MacBook Air. See the article here.
Hope this will help,
Clinton
Oh, you can also install on your drive from the flash drive, too.

Webcam not working for Macbook Air 2013 after upgrading to OSX Mavericks? Yahoo/ Google/Skype cam chats not working. Facetime works though. Any updates of Mavericks released to fix this?

Webcam not working for Macbook Air 2013 after upgrading to OSX Mavericks? Yahoo/ Google/Skype cam chats not working. Facetime works though. Any updates of Mavericks released to fix this?

I have a MacBook Pro Retina display: 15.4-inch late 2015 with OS X Mavericks install, only on second week.
Insight works on FaceTime, Skype, but yahoo program does not show insight cam in dropped down.
Now when I got my new MacBook Pro, I down loaded all new Skype (worked tested), FaceTime (Worked Tested), Yahoo (not worked)
Fix:
With the new Maverick you have to use there messager program Version 8.0 (4218). Once I add my yahoo account video works again.
It also supported AOL, AIM, Google Talk, Jabber.
Guess I miss it frist time... hope this helps...

Installation hangs - OSX upgrade on MacBook Air

I am attempting to upgrade OSX on my MacBook Air. The installation hangs at "Time remaining: Less than a minute" and eventually cycles off. The error log indicates "missing CoreServices." This has been going on for > 24 hours. Any advice?

Tried to upgrade a Macbook Air with 10.6.8 Snow Leopard to Mavericks from the Apple store. Nothing seemed to happen when clicking on the dowload button and the request APPEARED to hang. The download button changed to a light grey for a few seconds, then came back as a clickable download button. There was no progress bar in the downloads section. This problem is known to Apple but was not solved as of November 1, 2014.
In fact, the upgrade download button did trigger the download. The only indication one gets is in the dock, where the OS X icon will show only "Download... ". There is a minuscule progress bar under the icon and it will take 30 minutes or so before progress starts to show in blue!
If you use an internet wire connection with a router (without other computers connected), rapidly blinking lights on the router will confirm high traffic to the MacBook Air.
The complete download took over 3 hours, via the USB/ethernet port. I also made sure the computer had power supplied by the wall charger. For some reason, the download caused the light on the magnetic plug of the charger cable not to show red or green, and the battery remaining time was not operational on the computer screen.
Installation took more than double the time shown as remaining. You just have to be patient.
After rebooting, the fan was constantly on and the battery remaining time was still not functional on the header bar. It took about an hour for Spotlight to re-index the computer.
All upgrade activities completed, after restarting the computer, the fan was running loudly and the battery remaining time was not working.
I tried the following as recommended for a similar problem reported after installation of Mountain Lion. By pressing Control-Shift-Option and the power button all at once for a second, the computer switched off. Pressing the power button to restart the computer showed everything was back to normal: no fan noise, and the battery remaining time percentage works again. Plugging in the charger also brought again the red charging light.

HELP! I can't install OSX Mavericks on MacBook Air

Help! I just download and install OSX Mavericks on MacBook Air (2012), its already downloaded and installed but when booted, the wheels machine on the screen keep running. its even more an hour and i restarded it for severel times. but still not working. should I wait until the installation finished? for how long? 1, 2, or 3 hours?

Then the hard drive is corrupted. You will need to erase it then reinstall:
Install or Reinstall Mavericks, Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

What is the preferred anti-virus/malware software for MacBook Air

What is the preferred anti-virusmalware software for MacBook Air?

None is required.
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
          Mac OS X Snow Leopard and malware detection
          OS X Lion- Protect your Mac from malware
          OS X Mountain Lion- Protect your Mac from malware
          About file quarantine in OS X
If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
From user Joe Bailey comes this equally useful advice:
The facts are:
1. There is no anti-malware software that can detect 100% of the malware out there.
2. There is no anti-malware that can detect anything targeting the Mac because there
     is no Mac malware in the wild, and therefore, no "signatures" to detect.
3. The very best way to prevent the most attacks is for you as the user to be aware that
     the most successful malware attacks rely on very sophisticated social engineering
     techniques preying on human avarice, ****, and fear.
4. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on
    your computer is intended to entice you to install their malware thinking it is a
    protection against malware.
5. Some of the anti-malware products on the market are worse than the malware
    from which they purport to protect you.
6. Be cautious where you go on the internet.
7. Only download anything from sites you know are safe.
8. Avoid links you receive in email, always be suspicious even if you get something
    you think is from a friend, but you were not expecting.
9. If there is any question in your mind, then assume it is malware.

How to download lion in macbook air 2011

hi
i can not lion in macbook air new 2011
because ask apple id !!!
plz help

You need to set up an Apple App Store account in order to be able to dowload software from the App Store. An App Store account requires an Apple Id (normally this is your email address). If you don't have one you can set one up. Note this is the same id you use for iTunes so if you have an iTunes account use those credentials.
If you have a new MBA 2011 (i.e. one bought after about July this year) it will already be running Lion. To make sure go to the Apple menu (top left corner of screen) and select About this Mac. If the version of Mac OS X shown is 10.7 then that is Lion.

Nope. You can purchase a Snow Leopard DVD for $29.00 through an Apple retailer or ordering from AppleCare:

Osx lion on macbook 3,1

Is it possible to install osx lion on MacBook 3,1 ?

There are several good sets of instructions on how to create an installation backup, whether flash drive or DVD. One such is this MacWorld article. There are other approaches using Recovery Assistant that are good also. While these articles say Lion, they are also true for Mountain Lion...both Mac OS Xs have an installer that you must use to make the backup before you install it as it is deleted as the last step in the installation process. The trick is to download the installer, make a copy in another location on your system, and use that copy to create a backup drive/disk.

OSX Lion for free?

I just got the macbook pro, and apparently I'm suppose to get OSX Lion for free because I bought it in the month of July. But I dont know how to go about that? Can someone please help?

I think you mean Mountain Lion, and July isn't over yet.

HT1338 I failed to re-install Mac OSX after I removed it while removing my personal info. I forgot my Apple ID & password at the time. I have now recovered them with my windows type spare computer. How can I reinstall OSX on my MacBook Air?

Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your newly installed 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. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.
This will install the OS originally installed on your computer. If you plan to sell or give away the computer, then do not upgrade it or the purchaser will not be able to use it.

Offline Installer for Macbook Air 2011 & Mac Mini 2011

I understand that Macbook Air 2011 and Mac Mini 2011 uses a pre-installed OS X Lion with a different build number (11A2063).
However, it seems that with 10.7.2 , there is only 1 build number: 11C74 , as per http://support.apple.com/kb/HT1633 , does it mean that 10.7.2 is a unified version of the OS X Lion for all mac products?
Therefore, would it be possible to purchase & download the Lion Installer from Mac App Store , extract the InstallESD.dmg and use it as a offline Lion installer for Macbook Air 2011 / Mac mini 2011?
P.S. I am seeking an offline solution because the recovery partition has been damaged, the internet recovery doesn't work (error 3403F & 4403F), and the recovery disk I have created with http://support.apple.com/kb/dl1433 showed an error "could not find installation information for this machine". And the Apple Authorized Service Providers are charging $150 for a simple restoration of the recovery partition.

"does it mean that 10.7.2 is a unified version of the OS X Lion for all mac products?"
Yes.
"Therefore, would it be possible to purchase & download the Lion Installer from Mac App Store , extract the InstallESD.dmg and use it as a offline Lion installer for Macbook Air 2011 / Mac mini 2011?"
I don't believe there is a 10.7.2 stand alone installer. 10.7.2 is an update file.

This is firmware restoration for pro. It restores the EFI firmware. It is about 30 MB.

This is firmware update for air. It is about 4 MB.
I wonder if there is firmware restoration for air.
