How do you clean out a start up disk

Hi, How do you clean out a Start up Disk to gain more room?
Thanks

For information about the Other category in the Storage display, see this support article. If the Storage display seems to be inaccurate, try rebuilding the Spotlight index.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation—not the mythical 10%, 15%, or any other percentage. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
Launch the built-in Terminal 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 Terminal in the icon grid.
Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Ignore any other messages that appear in the Terminal window.
The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with the app, quit it and also quit Terminal.

HT3680 How do I clean up my start up disk

How do I clean up my start up disk

If you mean that you want to free up space: move some large library to another disk (movies in particular), and move old files that you do not need (often) to another disk.
Using socalled "cleaners" is counter productive because they clean caches, and then they are filled again which costs speed: OSX has daily/weekly/monthly clean routines already.
Taking out languages that you do not need and the binary parts of apps, which can be done by some cleaners is not only counterproductive and often generating crashes, but this does not free up significant space.

Great article here:

HT201364 How do I delete from my start up disk

HOW DO I DELETE FROM MY START-UP DISK.....I WANT TO INSTALL OX MAVERICKS AND MUST DELETE FOR MORE SPACE

You should never, EVER let a conputer hard drive get completely full, EVER!
With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
If it does, it's time for some hard drive housecleaning.
Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
Have you emptied your iMac's Trash icon in the Dock?
If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
Other things you can do to gain space.
Once you have around 15 GBs regained, do a search, download and install OmniDisk Sweeper.
This app will help you locate files that you can move/archive and/or delete from your system.
STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
Download an app called OnyX for your version of OS X.
When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
Typically, iTunes and iPhoto libraries are the biggest users of HD space.
move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
Good Luck!

My MacBook Pro doesn't start; in safe mode shift CMD V the message "disk0s2: media is not present" is written on the screen repeatedly but the MacBook doesn't start. Do you have any ideas of why this should be or what I should do to resolve this?

My MacBook Pro doesn't start; in safe mode <shift CMD V> the message "disk0s2: media is not present" is written on the screen repeatedly but the MacBook doesn't start. Do you have any ideas of why this should be or what I should do to resolve this? Thanks Eamonn

Thanks for these suggestions: I have tried safe mode re-starts (both "verbose" and simple "shift" + power) to no avail. I get the error message "disk0s2: media is not present". Following this I inserted the installation disc and from there ran disc utility. The "Verify Disk" indicated an error " invalid sibling link" which it could not repair.
I also tried to completely re-format/erase the disk, but again got an error message "disk object invalid or unable to serialize".
Any ideas of what could be causing this or the best solution? I fear I am fast running out of options.

HT1338 how do you delete from the start up disk- message keeps saying ful

How do you delete files off of the start up disk to make more space?

You open a Finder window, navigate to the location with files you want to delete. In the window, drag the file you want to delete to the Trash (waste basket) icon in the Dock, and release it there. Periodically, click-hold (or right click) on the Trash icon and select Empty Trash, which will delete the files to free up the disk space. (You can select more than one file at once.)
A good place to initially look is your Downloads folder, which normally has a quick link in the sidebar of a Finder window. Most people tend to accumulate stuff they don't need to keep there.

How do I make space on start-up disk

Hi,
I recently upgraded to Lion X. Now I keep getting notices that my start-up disk is almost full. How do I make more space? I'm afraid of deleting things that are important for my Mac. Please break it down for me step by step. This is my first Mac, so I'm not too familiar with this laptop or Lion X. Thanks.
Hilda

Hilda,
Generally, anything in visible folders under your user name in the finder will be documents that you can safely move to an external drive or delete. You should see separate folders for Desktop, Documents, Downloads, Movies, Music, Pictures, etc. None of the files in these folders should be critical to the operation of your mac.
Safest bet is to get an external drive and move things like pictures and movies off of your main drive. These can be especially large files and take up a lot of space. What I do is build a similar group of folders on the external drive, and that makes it easy to keep things organized. Make sure you move the files or copy and then erase as OS X does a copy by default.
Also, check to make sure your trash is empty, and your downloads folder, it can get full of dmg images and other typical downloads, and most of these can be safely erased unless you don't have access to the original source any more. Hope this helps.

How do i get a bigger start up disk installed in my mac air?

Currently i have everything saved onto my external hard drive. There is absolutely noting on my mac in terms of memory. I have started doing some video editing and have noticed the computer freezing and working slower. The start up disk is the basic size and i would like to increase the size to help speed up the computer.
How do i do this?

The MacBook Air is not user upgradeable and though some try to do so themselves, that will void any support and service from Apple.
Ty contacting your Apple store genius bar and see if they have the ability to upgrade the solid state storage on an MBA. Or, you can try to find an Apple Authorized Service Provider as they usually can install a new SSD for you.

HT201210 How do I make room in start up disk

I am attempting to update my iphone 5 software, however, when I connect to itunes it gives me a message that it cannot complete my request becasue the start up disk is full.
How do I create room in my start up disk?
Thanks in advance!

A startup disk error almost certainly refers to your computer, not the iPhone.
First question: Are you running the most recent version of iTunes (11.0.1)? If not, get it at:
http://www.apple.com/itunes
I would guess you may well be running an iTunes version that is too old to support the iPhone 5.
