Welcome to the Apple Support Communities
iChat is installed. If you have got OS X Mountain Lion, you have Messages instead of iChat, but it's not possible to use iChat on OS X Mountain Lion

I was sent an email which I thought was legit . I opened an attachment (zip file) but nothing in it. I phoned the bank to double check, and of course the email was bogus. How can I tell whether my macbook air version X.9.4 has a virus or not.

No Mac viruses are propagated through email.
Be vigilant for suspicious activity as you normally should be, but do not download or install some "anti-virus" utility in an effort to fix a problem that does not exist. That's a well-worn path to certain misery.

I just upgraded to a new MacBook and my wife is inheriting my old MacBook Air. How can I change the her MacBook Air to now be fundamentally hers? That is, so the House Icon under Users folder is her name and not mine? Also the default AppleID for purchase stubbernly remains my own.

You do not mention it, but I will assume you are running OS 10.9.1.
Go to: Apple menu / System Preferences / Users & Groups. Click the padlock and enter your password.
Click the + (plus sign) and set up a new account for your wife. You have to enter a bunch of info. And then create the correct Login Options. Automatic login does not require a password from the selected user.
When that is done, verify the account works by restarting the computer and login as your wife.
Make sure that any applications in your own Users folder that will be needed are moved to the Applications folder in your wife's Users folder.
Now go back to Users and Groups, click the padlock and authenticate, select your own account, and hit the - (minus sign). This step cannot be reversed, so you might want to wait a few days before doing it.
When your wife is logged in, the App Store will know.

How can I back up a MacBook Air on a Mac Pro Hard Drive using Time Machine?

Want to back up a MacBook Air on a Mac Pro with a spare hard drive. Sharing allows Time Machine to find the hard drive, but get a drive busy message when time machine tries to back up onto the drive.
Any suggestions?

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console 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 Console in the icon grid.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter the word "Starting" (without the quotes) in the String Matching text field. You should now see log messages with the words "Starting * backup," where * represents any of the words "automatic," "manual," or "standard." Note the timestamp of the last such message that corresponds to a failed backup. Now
CLEAR THE WORD "Starting" FROM THE TEXT FIELD
so that all messages are showning, and scroll back in the log to the time you noted. Select the messages timestamped from then until the end of the backup, or the end of the log if that's not clear. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message.
If all you see are messages that contain the word "Starting," you didn't clear the text field.
If there are runs of repeated messages, post only one example of each. Don't post many repetitions of the same message.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Some personal information, such as the names of your files, may be included — anonymize before posting.

How can I speed up my MacBook Air?

Hi folks,
My MacBook Air has gotten painfully slow over time but I can't afford to buy a new one right now. It freezes for a few seconds at a time, all the time, especially when I am using Chrome.* Any ideas for how to speed it up?
Specs are:
Model: 13-inch, Late 2010
Processor: 1.86 GHz Intel Core 2 Duo
Memory: 2 GB 1067 MHz DDR3
Software: Mac OS X Lion 10.7.5 (11G63b)
Graphics: Graphics NVIDIA GeForce 320M 256 MB
Storage: The Mac partition is 75 GB, of which 44 GB are free (there is also a 45GB Bootcamp partition).
I was running out of disk space, which I thought was causing the problem by cramping the space available for the swapfiles, which in turn was requiring extra disk activity (you can see that discussion here). There is a clear correlation b/w disk activity and CPU Usage (the two screenshots were taken back to back last night; the dock icon for Activity Monitor is showing CPU history):
However repartitioning to add another 35GB of free space to the Mac partition didn't do anything. In fact, the swapfile sizes are exactly the same as they were two weeks ago when I posted the other question (this is from just now):
I was thinking about buying an aftermarket SSD to increase the storage size, but if increasing the partition size didn't help it doesn't seem that will either.
Thanks much!
* The big memory and CPU hog is Chrome, and in particular gmail, but my workflow is pretty dependent on working in the cloud. I use Firefox and Safari from time to time, but my experience with those is that they run all tabs in a signel process, so to free up memory you have to close the entire browser, and if one tab crashes the whole browser does, whereas with chrome you can kill individual tabs if they freeze and/or to free up their memory.

You need more RAM if that's possible in your model. I think you can go up to 4 GBs. You will use more swap space as memory availability declines.
About OS X Memory Management and Usage
Using Activity Monitor to read System Memory & determine how much RAM is used
Memory Management in Mac OS X
Performance Guidelines- Memory Management in Mac OS X
A detailed look at memory usage in OS X
Memory Usage Performance Guidelines- About the Virtual Memory System
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.
Adding RAM only makes it possible to run more programs concurrently. It doesn't speed up the computer nor make games run faster. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent. It will improve the performance of applications that run mostly in RAM or when loading programs.
Kappy's Personal Suggestions About OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utility is: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption. Drive Genius provides additional tools not found in Disk Warrior for defragmentation of older drives, disk repair, disk scans, formatting, partitioning, disk copy, and benchmarking.
Four outstanding sources of information on Mac maintenance are:
1. OS X Maintenance - MacAttorney.
2. Mac maintenance Quick Assist
3. Maintaining Mac OS X
4. Mac Maintenance Guide
Periodic Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) See Mac OS X- About background maintenance tasks. If you are running Leopard or later these tasks are run automatically, so there is no need to use any third-party software to force running these tasks.
If you are using a pre-Leopard version of OS X, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced after Tiger. (These utilities have limited or no functionality with Snow Leopard, Lion, or Mountain Lion and should not be installed.)
Defragmentation
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive except when trying to install Boot Camp on a fragmented drive. But you don't need to buy third-party software. All you need is a spare external hard drive and Carbon Copy Cloner.
Cheap and Easy Defragmentation
You will have to backup your OS X partition to an external drive, boot from the external drive, use Disk Utility to repartition and reformat your hard drive back to a single volume, then restore your backup to the internal hard drive. You will use Carbon Copy Cloner to create the backup and to restore it.
1. Get an empty external hard drive and clone your internal drive to the
       external one.
2. Boot from the external hard drive.
3. Erase the internal hard drive.
4. Restore the external clone to the internal hard drive.
Clone the internal drive to the external drive
1. Open Carbon Copy Cloner.
2. Select the Source volume from the left side dropdown menu.
3. Select the Destination volume from the left side dropdown menu.
4. Be sure the Block Copy button is not depressed or is ghosted.
5. Click on the Clone button.
Destination means the external backup drive. Source means the internal startup drive.
Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the external drive and click on the upward pointing arrow button.
After startup do the following:
Erase internal hard drive
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your internal hard drive (this is the entry with the
       mfgr.'s ID and size) from the left side list. Note the SMART status of the
       drive in DU's status area. If it does not say "Verified" then the drive is
       failing or has failed and will need replacing. SMART info will not be
       reported on external drives. Otherwise, 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. Set the format type to Mac OS Extended
       (Journaled.) Click on the Options button, set the partition scheme to
       GUID then click on the OK button. Click on the Partition button and wait
       until the process has completed.
Restore the clone to the internal hard drive
1. Open Carbon Copy Cloner.
2. Select the Source volume from the left side dropdown menu.
3. Select the Destination volume from the left side dropdown menu.
4. Be sure the Block Copy button is not selected or is ghosted.
5. Click on the Clone button.
Destination means the internal hard drive. Source means the external startup drive.
Note that the Source and Destination drives are swapped for this last procedure.
Malware Protection
As for malware protection there are few if any such animals affecting OS X. Starting with Lion Apple has included built-in malware protection that is automatically updated as necessary.
Helpful Links Regarding Malware Protection:
1. Mac Malware Guide.
2. Detecting and avoiding malware and spyware
3. Macintosh Virus Guide
For general anti-virus protection I recommend only using ClamXav, but it is not necessary if you are keeping your computer's operating system software up to date. You should avoid any other third-party software advertised as providing anti-malware/virus protection. They are not required and could cause the performance of your computer to drop.
Cache Clearing
I recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc. Corrupted cache files can cause slowness, kernel panics, and other issues. Although this is not a frequent nor a recurring problem, when it does happen there are tools such as those above to fix the problem.
For emergency cleaning install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. (AppleJack works with Snow Leopard or earlier.)
Installing System Updates or Upgrades
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Backup and Restore
Having a backup and restore strategy is one of the most important things you can do to maintain your computer. Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner.
2. Deja Vu
3. SuperDuper!
4. Synk Pro
5. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance and backup and restore.
Always have a current backup before performing any system updates or upgrades.
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity or 20 GBs, whichever is greater, as free space. Avoid installing utilities that rely on Haxies, SIMBL, or that alter the OS appearance, add features you will rarely if ever need, etc. The more extras you install the greater the probability of having problems. If you install software be sure you know how to uninstall it. Avoid installing multiple new software at the same time. Install one at a time and use it for a while to be sure it's compatible.

Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with a visit to: OS X Maintenance - MacAttorney.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Repair the Hard Drive - Lion
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
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.
Restart your computer normally and see if this has helped any. Next do some maintenance:
Suggestions for OS X Maintenance
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.

Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.

Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

How to install Microsoft Office on MacBook Air?

I just bought my first ever Apple MacBook and I am realy having hard time with it.
Please someone tell me how to install the Microsoft Office 2011 on MacBook Air.
Thank you so much!

bdbiceinparadise wrote:
Just go to MS Office, download a free trial, enter the product key from the MS Office software that you purchased, and voila! So easy!
Does this solution work on different versions of software (in this case MS Office)? I don't keep up with all the releases so the dates are probably wrong in the following examples. Lets assume I owned MS Office 07 and I wanted to use your solution. I assume the MS website DOESN'T offer free trials of outdated software. So, I go on their website, download MS Office 2011 and then enter my product key from MS Office 2007. Are you saying that will work?
Personally for me, I don't give two hoots about getting the latest MS Office. So, if I have a working copy of an earlier edition, that's the one I want to install. And yes, for you NO-NO people, I do remove the software from my previous computers when I do this before I sell them.
Even if I could upgrade my previous version, I wouldn't want to as it would be a waste of my time during the learning curve. In fact I'm paying this penalty now in that I'm using MS Office 08 that my wife bought (3 computer version) and insisted I put on my computer to help her on her's. I was using MS Office 03 and hate the 08 pull down menus. Since I use the program infrequently, I find myself staggering around trying to find this and that when with the '03 version, it would be simply click and done.
