How can i clean start up disk

can you tell me how to make space on my mac air

Start by adding an extenal hard drive where you can store bulk material...there are a lot of good ones at OWC, http://www.macsales.com
Move your photos, music and videos to libraries you create for things like iTunes and iPhoto to use on the external drive. Then clear out that space on the internal storage. Be cautious about what you delete from the internal storage, stay far away from all of the Mac OS X system folders.

Those things you did on your PC you need not worry about on your Mac. Most is done behind the scenes.
Kappy's Personal Suggestions About OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: 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. Drive Genius provides additional tools not found in Disk Warrior. Versions 1.5.1 and later are Intel Mac compatible.
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.)
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 since Tiger. (These utilities have limited or no functionality with Snow Leopard, Lion, or Mountain Lion and should not be installed.)
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. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also 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.
For emergency repairs 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. (There is no confirmation that this version also works with Lion or later.)
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.
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. Data Backup
3. Deja Vu
4. SuperDuper!
5. SyncTwoFolders
6. Synk Pro
7. Synk Standard
8. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, 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.

How can I change start up disks?

The hard drive on my laptop is partitioned with 2 different operating Systems. There seems to be difficulty with the preferences of one of the systems and I anm unable to boot from the other partition. I believe there is a shortcut at start up but I don't remember.

It's Option.

My Mac is running slowly and having some gliches when opening programs. How can I clean up the disk to make it more efficient?

learn how to use Recovery Mode
Don't do anything until you can restore and have repaired the disk drive.
Post should get moved to either ML (10.8,.4) or iMac forum
Swap out the hdd for an SSD : )
Don't do anything to clean it up unless you don't know how to first remove browser history from within the programs; low on disk space (I consider more than even the 15% minimum, more like 3--40%)
And do you have page outs? more than enough RAM? what actually leads you to ask? Programs aren't opening properly?
Sometimes it is easier to take the long road: just reinstall and restore.

How can I get a recovery disk for Satellite P300-1CI?

Hi everybody,
first, sorry for my english, I'm a belgian and I speak french.
Yesterday I bought a toshiba Satellite P300-1CI, when I started, I must installed Vista home.
I would like to format my disk and reinstall my old Windows XP.
My question is : How can keep an image disk with Vista? I don't have an installation disk of Vista and don't know my registration key of it.
How can I have a recovery disk ?
Can you help me please.
PS : Sorry for my english

Hi mate
User manual is really interesting document and in most cases it answer all you questions ;)
Anyway, the Toshiba recovery disk should be created before you would format and install on the HDD.
You have to use the preinstalled Toshiba Recovery Disk Creator application in order to create the Recovery DVD.
Now to you other question;
The Vista image which is preinstalled and placed on the Recovery disk (after recovery disk has been created) is activated already and you dont need to insert any keys or activate anything.

How can i clean up my mac for free

how can i clean up my mac for free

You may find this post helpful 1doran: have problems cleaning up my mac
Read the cautions regarding deleting language resources.
A reliable program that claims the intelligence to automatically discriminate between required and superfluous files does not exist. Such one-size-fits-all "clean up" utilities frequently don't know the difference between required system components and trash, and can easily result in a broken Mac.
If you are running low on disk space you can buy a bigger disk. They are not expensive. In the meantime you can read the techniques here to determine if there are any large files you can safely delete using the tools already built into every Mac, including recommendations for some free utilities you can use to easily identify large files.

How can i clean off all my third party applcations

How can i clean off all my third party applacations from the internet?

Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, Easy Find, instead. Download Easy Find at VersionTracker or MacUpdate.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are also several shareware utilities that can uninstall applications:
AppZapper
Automaton
Hazel
CleanApp
Yank
SuperPop
Uninstaller
Spring Cleaning
Look for them at VersionTracker or MacUpdate.

How can I erase my hard disk with OS X 10.8.2?

How can I erase my hard disk with OS X 10.8.2?

If you want to erase the hard disk and reinstall OS X, follow these steps:
1. Back up your data to an external disk if you don't want to lose everything. When you erase a hard disk, everything is deleted.
2. Press Command and R keys while your Mac is starting to start into OS X Recovery, and open Disk Utility.
3. Select Macintosh HD on the sidebar, go to Erase tab and erase the disk.
4. After erasing the disk, close Disk Utility and reinstall OS X, so OS X will be installed with factory settings.
Don't forget to install iLife applications after the installation, if you need them. They come in the Applications DVD (if your Mac came with Snow Leopard or older), or open App Store > Purchases and download them

How can I make a bootable disk for Mountain Lion?

How can I make a bootable disk for Mountain Lion?

Make Your Own Mountain/Lion Installer
1. After downloading Mountain/Lion you must first save the Install Mac OS X Mountain/Lion application. After Mountain/Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Mountain/Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash 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.
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.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
3. Locate the saved Mountain/Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
4. Plug in your freshly prepared USB flash drive. You are going to clone the content of the InstallESD.dmg disc image to the flash drive as follows:
Double-click on the InstallESD.dmg file to mount it on your Desktop.
Open Disk Utility.
Select the USB flash drive from the left side list.
Click on the Restore tab in the DU main window.
Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
Drag the mounted disc icon from the Desktop into the Source entry field.
Double-check you got it right, then click on the Restore button.
When the clone is completed you have a fully bootable installer that you can use without having to re-download Mountain/Lion.
Note: The term Mountain/Lion used above means Lion or Mountain Lion.

How can I clean up queue one-time on Sun Java system messaging 6.3

Hi,
<address>Our Email server have a problem, When I run _./imsimta qm directory tcp_local_, There are about 5 Millions of messages in the queue.</address>
Now our Email server send messages very slowly, how can I clean up queue one-time?
the command _./imsimta qclean_ is very slowly.
What can I do to prevent this problem?
our Email server version is :
Sun Java(tm) System Messaging Server 6.3-6.03 (built Mar 14 2008; 32bit)
libimta.so 6.3-6.03 (built 17:12:37, Mar 14 2008; 32bit)
SunOS email-1 5.10 Generic_120011-14 sun4u sparc SUNW,Sun-Fire-V890
Thank you !

If you have more than 100,000 messages in the queue, then look at the MAX_MESSAGES parameter in [the job_controller.cnf file|http://wikis.sun.com/display/CommSuite/Job+Controller+Configuration+File]. If the parameter is not specified, it defaults to 100000. If you have more than that number of messages in the channel queues, it will take a long time for new/legitimate messages to be sent because job_controller is only considering the first 100,000 messages in the queue.
If you get into the "imsimta qm" command do do "sum -database", it will show a summary of what job_controller has in its internal cache and therefore what job_controller is working on. If you compare that to "sum -directory" you will probably see a difference.
If these are all legitimate messages, you need to increase MAX_MESSAGES, cnbuild, and restart job_controller.
If they are not, then preventing this in the future will require determining how they got into your queue and correcting that.
As for removing them, the "imsimta qm" commands allow you to select messages by various criteria and then you can "return" or "delete" them. But yes, that will take a long time if there are many messages because it is a single threaded process and it needs to open and examine each message. You may be able to accomplish the task more quickly with a shell script that works on individual channel queue subdirectories and then run multiple copies of that script in parallel. After you have cleaned out the queue, restart job_controller.
Also, you might want to consider [the subdirs channel keyword|http://msg.wikidoc.info/index.php/Subdirs_and_nosubdirs_Channel_Options].

I have duplicative song files in my library that are grayed out. This seems to cause a syncing problem to my ipod or iphone. How can I clean up this mess?

I chose to let iTunes rearrange my files and it appears to have duplicated them in my computer's drive. So now I have the same folders/files directly under my D drive (second computer hard drive) and also in the iTunes Music Folder that iTunes created. Wasn't sure what to do so I did another import and now I have files in my library that are grayed out with the small i symbol in the circle next to them. I also have the working (bolded) files too. How can I clean this up?

Is there a way to override the 256kbps "conversion" when uploading to iCloud?
No. All music that is mirrored in the cloud will be AAC@256 Kbps.
Musicman05 wrote:
Along the same lines, if I "download" a song from my library to my iPhone, then plug my iPhone into my computer and sync the song file from my computer, will the higher quality original file overwrite the 256 one?
No, because with iTunes Match enabled on an iOS device traditional syncing of music via USB is disabled. All music management is done directly on the device.
Musicman05 wrote:
Also, if I want to syncronize another computer using iTunes match, how can I get the higher quality audio files? Will I simply have to transport all of them by an exernal hard drive or thumb drive?
You will first have to copy the high-quality audio files to the computer, add them to the iTunes library then enable iTunes Match.
