Cleaning the start up disc

when I first set up this mini, I used migration assistant, to more the data, I thought, but whole old computer was moved and partitioned the mini. Now, I get the start up disc full and while I've removed most programs I'd added (like a few games), nothing helps - even CleanMYMAC. don't want the partition, and suspect there are backup files taking up space from the iPADl. Haven't yet gotten an external drive to remove the media, but my old iMAC seems to have more space with more media. Can I get rid of the partition so have the whole space or what othe things can I do? not very techy, just enough to be dangerous.

If you mean that you have two partitions, the first is your system/boot volume, and you have no use for the second one or the files on it, yes, you can repartition the drive and expand the first partition.
You have to boot from your install CD (if you have a CD drive) or your Lion Recovery Partition (hold down cmd-R on reboot).
Run Disk Utility from the Utilities menu once you've booted from the installer/recovery volume, and use the Partition tab to remove the second partition and maximize the first if needed by dragging its rectangle to fill the available space and click Apply.

Can I use the start up discs for my Powerbook to install 10.4 on my iMac?

Hi, I just bought a used Powerbook G4 1.67GHz and wanted to use the start-up discs with OS 10.4.2 that came with the Powerbook on my older iMac G4 800MHz. What I really want to do is wipe the hard drive clean on my older iMac and then reinstall OS 10.4.2 and associated programs from the discs that came with the Powerbook. Will this work? I do not want to wipe everything off of the older iMac and then realize that these discs will not work on the older machine. There are two discs that say PowerBook G4 15-inch and 17-inch Mac OS X Install Discs version 10.4.2 AHT version 2.5.2 Disc version 1.0

Welcome to the Apple Support Communities
Lion uses Recovery to reinstall OS X. Press Command and R keys when your Mac starts, open Disk Utility, erase the drive and reinstall Lion. The other Mac has probably got its hard disk damaged, so take the Mac to an Apple Store

Clean out start up disc I Mac g5

How can I clean out the start up disk. I do not have enough space to import video into I movie on my G5.

If your hard drive is getting full,
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 Mac'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.
Look through your other Mailboxes and other Mail categories to see If there is other mail you can archive and/or delete.
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!

How do i clean up start up disc space

I am getting a message saying that my start up disc is full. How do I clean it up?

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 a photo or iTunes library will corrupt the library. Changes to such a 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 and start typing the name.
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.

The start up disc is full

I have an iMac and get a sign that the start up dis is full. There is a free memory space of 261 Gb. What is the problem and how can I fix this?

"Memory" is RAM. This is a hard drive free space issue. Anyway, see the More Like this in the sidebar ------------->

My HD is full of mystery data? getting the "start up disc is full" error.

For a while I have been getting the "your startup disc is full" prompt,
which is strange because I have no where near 27G's on the HD.
Looking in the finder I see my file vault is listed with an extra 10GB that is not there.
I ran the maintenance scripts, they did not fix the problem.
Any help will be appreciated! thanks

Jonathan,
what happens if I take off all the files and there still is not enough room?
Good question. One possible solution: Download Monolingual and remove all languages you do not need. On my computer this freed up 1.5 GB today. After that you should have enough disk space to turn off FileVault.
Do not forget to mark the tread as "SOLVED" once this is accomplished.

How do I delete all data (wipe the MacBook clean) WITHOUT start up discs?

I need to wipe my Macbook clean for a family member to buy... I would just delete files no longer needed but I think some of my progams are corrupt (they work improperly) so I'd rather just give them the computer with a fresh start. It's a Mac OSX 10.6.8, not entirely sure if it's Snow Leopard or Lion or whatever the newer ones are (I was given this laptop) and I don't have the disc it came with. How do I do this, if possible with out any disc?
If not possible, what's the most efficient way of deleting everything with out causing more corruption and setting it as close as possible to factory?

"If not possible, what's the most efficient way of deleting everything with out causing more corruption and setting it as close as possible to factory?"
Your "family member" will need some OS X to use the MacBook - a blank drive will not be of no use. My local Apple Store sells the authentic 10.6. (http://store.apple.com/ca/product/MC573Z/A/mac-os-x-106-snow-leopard) Perhaps you (or your relative) can talk your local store into selling you a copoy.

HT201240 I want to resest the administrator password but I don't remember the old password and I don't have the start up disc. Is there a way around this?

I'm trying to install a program update and the password that I thought I set isn't working. I don't have any start-up disk and need help resetting the password.

Here's one method to reset the password without the install disc:
1. boot computer and hold the "apple" key and the "s" key.
2. wait for terminal show
3. release keys
4. type without the quotes: "/sbin/mount -uaw"
5. press enter
6. type without the quotes: "rm /var/db/.applesetupdone
7. press enter
8. type without the quotes: "reboot"
9. press enter
This will let you create a new admin account when you reboot your computer.
Also, without the discs, look at Mac OS X Tip - No Password, No Root, No CD? No Problem.
http://www.macobserver.com/tip/2003/06/16.1.shtml
Here is a way to get around not knowing the admin password on Macs.
To reset your OS X password without an OS X CD you need to enter terminal and create a new admin account:
   1. Reboot
   2. Hold apple + s down after you hear the chime.
   3. When you get text prompt enter in these terminal commands to create a brand new admin account (hitting return after each line):
          * mount -uw /
          * rm /var/db/.AppleSetupDone
          * shutdown -h now
   4. After rebooting you should have a brand new admin account. When you login as the new admin you can simply delete the old one and you’re good to go again!

My MacBook Air keeps saying the start up disc is full...but I haven't used all the memory...help

I keep getting a message to say my start disc is full and I cant understand why. I dont have a lot of things saved on it and it affecting the operating of my laptop ie, freezing/wont download new mail.
Anyone had this issue before? Any ideas whats going on?
Thanks

First, that's not Local Snapshots -- if there was only 200 MB free, any Local Snapshots had been deleted long before (they're automatically deleted to keep your drive below 80%).
If it starts shrinking rapidly again, see Where did my Disk Space go?
There are lots of possibilities, but your symptoms sound a bit like one (or both) of these:
• Something going wrong sending thousands of messages to your logs (per the yellow box in the above link). You'll need to fix whatever that is as well as delete the old log files.
• An app (or apps) with a memory leak, making OSX use ridiculous amounts of virtual memory (not listed in the link). While the space is shrinking, select Go > Go to Folder from a Finder menubar, then type /var/vm in the prompt. That will produce a list of your swap files. Those are created as needed; the first two are 67 MB, then each additional file is double the size of the previous one, so they can get pretty large. They're deleted and started over after a Restart.
(There's probably also a sleepimage file there the same size as your installed RAM. That's normal.)
