I have an '09 mac book pro running os x mavericks. How do I empty the startup disk?
I have an '09 mac book pro running os x mavericks. My startup disk is full. How do I empty it? I want to shift my videos to another external hard drive or delete them altogether.
I think you're asking how to free up some space. Either copy the files off to an external drive and delete them, or just delete them. Delete means drag to the trash. Then empty the trash.

How do I clear the scratch disk?
PS CC keeps telling me my scratch disk is too full. I don"t know where i is ti clear it out. I'm running Windows 8.
You define which disks to use for your scratch disk in Preferences-Performance. Ideally, a scratch disk is a separate disk drive with lots of free space on it. Every time you load brushes, swatches, make an edit that gets recorded to a history state, etc. information is written to the scratch disk. If you only have the one disk drive on your computer that you are running your OS, Photoshop, saving files, etc, it's possible to use up all the free space for scratch and not be able to save your file!
To immediately free up some scratch space that Photoshop is using, go to Edit-Purge, and remove some (or all) of the saved scratch information. Aside from that, make sure you delete anything not needed on your scratch disk(s) to free up more space. Buy an extra external hard drive of at least a few hundred gigabytes and set that as a scratch disk to avoid running out of scratch disk space. -
How do i clear my startup disk
on my storage display it shows 53 gigs of other. i have deleted almost everything from my laptop but still dont have enugh memory for software updates. how do i start
First, empty the Trash if you haven't already done so. Then reboot. 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. You also need enough space left over to allow for growth of your data. As far as I know, there is no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
If you're using Time Machine to back up a portable Mac, some of the available space will be used to make local snapshots, which are backup copies of files you've recently deleted. 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.
To locate large files, you can use Spotlight as described here. That method may not find large folders that contain a lot of small files.
You can also use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space. You can 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.
Proceed further only if the problem hasn't been solved.
ODS 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.
Install ODS in the Applications folder as usual.
Triple-click the line of text below to select it, then copy the selected text to the Clipboard (command-C):sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
Launch the 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 (command-V) into the Terminal window. You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
I don't recommend that you make a habit of doing this. Don't delete anything while running ODS 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 you're done with ODS, quit it and also quit Terminal. -
How do I set the Startup Disk to Boot Camp via ARD
All,
I typically use ARD and Set Startup Disk to image and reconfigure our lab computers (http://support.apple.com/kb/HT2789) via a network image, namely DeployStudio. This works well. Now I want to be able to set it to a local disk to boot into Windows 7 which we have setup with Boot Camp. I get nothing but Failed responses. I am hoping it is a matter of what name or format I need to use.
I have tried:
BOOTCAMP
Windows
Windows on BOOTCAMP
None of these work. HELP!
These are iMac 21.5's running 10.6.8. ARD is 3.5.1. Same for clients.have you considered using Send Unix Command to set boot Volume?
For instance if you have "Macintosh HD" and "Boot Camp". And you wanted to set the boot volume to "Boot Camp". You could try sending the unix command, as root:
bless -mount /Volumes/Boot\ Camp -setBoot
After setting this, if you reboot, the computer should boot to the Boot\ Camp volume. But One the computer boots to windows, getting them to boot back to the mac os x is going to be a whole other story.
FYI if your boot camp volume is labeled "Untitled" then you would send the unix command, as root, bless -mount /Volumes/Untitled -setBoot. -
How do I clear mt startup disk on my Macbook Pro?
I want to upload some pictures onto my computer but I need to clear some space first. My computer is around 3 years old so there is probably a ton of stuff I can delete from awhile ago.
Drag what you don't want to the trash and empty the trash. Why is there probably a ton of stuff on it? Select your hard drive and do a command-I. That will tell you how much free space is on it. Then it won't be probably.

How can I remove files from the startup disk
I am getting a screen when I am trying to quit saying the "MAC OS X startup disk has no more space available for application memory" by closing the windows and removing files from the startup disk will help.
How do I do this?That error message is misleading. Your problem is excessive swapping of data between physical memory and virtual memory.
That can happen for two reasons:
You have a long-running process with a memory leak (i.e., a bug), or
You don't have enough memory installed for your usage pattern.
Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
In the Activity Monitor application, select All Processes from the menu in the toolbar, if not already selected. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
The process named "Safari Web Content" renders web pages for Safari and other applications. It uses a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider it a prime suspect.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details. -
How do I restore a disk image on the startup disk?
Hello,
Where do I begin? Ok, my computer is an iMac and I mainly use OS 10.6.8. I have partitioned the disk into three parts: Snow Leopard, Lion and Tiger ( and I'm thinking of deleting Tiger). The main OS I use on my computer is Snow Leopard (10.6.8). I wanted to try out Yosemite so I upgraded the Lion partition and it soon became Yosemite. I was able to switch back and fort a couple of times last night, but today, when I went to the Startup Disk to go to Yosemite the disk image for Yosemite was gone and it only shows the disk image for Snow Leopard. I did a little research and if I'm not mistaken and read correctly, it indicates that Apple has done away with the disk image for Yosemite? How is one to switch back and forth between systems? Thank you for any insight to my question. -Della
P.S. If I have posted in the wrong category, please feel free to repost in the correct category, but please let me know. Thank you!If it's a Windows executable file other than a self-extracting zip, you won't be able to open it without installing Windows; on a PowerPC Mac, this requires Virtual PC or the Q emulator.
If it's a self-extracting zip, StuffIt Expander will open it.
If it's actually a disk image, change its extension to dmg or iso and double-click it.

How to fix this error? The startup disk cannot be partitioned or restored to a single partition.
Hey guys,
I am trying to install windows 7 ultimate 64 bit via bootcamp assistant. I open bootcamp assistant from utilities and i get the second window and try to click continue and i get a pop up, saying "The startup disk must be formatted as a single Mac OS Extneded (journaled) volume or already partitioned by Boot Camp Assistant for installing Windows." I looked around on the internet, i found that my internal HD must be set to OS Extended (Journaled). I went into disk utility and i clicked partition tab and the option was set to OS extended (journaled). Any ideas on how to overcome this error so i can install windows 7?Error is:
1: common
2: misleading and poorly worded
3: space must be:
A: contiguous, that means unfragmented and in ONE section, not multiple
B: files cannot be loced, anchored or in such a manner as to prevent or block partition operation
C: to move, unlock and shuffle files requires booting from another drive or device
Shrink the HFS+ volume by as much or more than you need to set aside to use
If that does not,
Try iDefrag from another hard drive or by burning and using its own CD that is just for consolidating free space
Clone your system (should have backups already, clone is just bootable)
Erase and restore from clone - SuperDuper does consolidate files and free space and result in unfragmented (99% success rate)
None of which has to do iwth what that error message says. This error has been almost a daily threat topic - has gotten less but has not "gone away." -
how do i delete from the startup disk? I am trying to get Mountain Lion from the App store and it says that the purchase was not complete because i need 4.06 GB space to download OS x 10.8. and to remove items from my startup disk to increase space. How?
ThanksYou can use iCloud with 10.7.5. You do not need to upgrade to Yosemite. You should provide a minimum of 15 GBs of free space or 10% of the hard drive's capacity, whichever is greater.
Freeing Up Space on The Hard Drive
1. See Lion/Mountain Lion/Mavericks' Storage Display.
2. You can remove data from your Home folder except for the /Home/Library/ folder.
3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
4. Also see Freeing space on your Mac OS X startup disk.
5. See Where did my Disk Space go?.
6. See The Storage Display.
You must Empty the Trash in order to recover the space they occupied on the hard drive.
You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located. -
Error message: Backup Failed. However if the startup disk permissions are repaired one backup will succeed before the permissions are again repaired. How is this to be fixed?
Hi,
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
Then Repair the backup Disk... any change? -
Dear all,
I have this massage that says the startup disk is full, how can I decongest it?It would help to know what you were doing when you received the message. It is always wise to leave about 10 to 15% of your HDD capacity free so that there is plenty of workspace for temporary files and so on. If you have a lot of movies or thousands of photos (especially RAW files) then your disk very well might be reaching its workable limit. The safest solution is to have a reliable backup (such as Time Machine) where the contents are stored, then you could do a safety redundant backup of your movies, photos and audio by copying them to a different external HDD, then remove them from the internal drive. In that way they would be accessible for restoration by way of Time Machine, or they would be accessible as files from the external. The prices of external drives are now very low and affordable so the purchase of a 1TB or 2TB HDD is no longer prohibitive. Any long-time user will tell you that 'backup' + 'backup of the backup' [that is: redundant backup] is never a bad idea when working with important files. The time to do this is NOW before a drive failure not after when it might be impossible.

I have an iMac for work and I am leaving the company. How do I clear the computer so that my soon to be former company is unable to see my personal information Ie. - internet, contacts, etc...
Follow these instructions step by step to prepare a Mac for sale:
Step One - Back up your data:
A. If you have any Virtual PCs shut them down. They cannot be in their "fast saved" state. They must be shut down from inside Windows.
B. Clone to an external drive using using Carbon Copy Cloner.
1. Open Carbon Copy Cloner.
2. Select the Source volume from the Select a source drop down menu on the left side.
3. Select the Destination volume from the Select a destination drop down menu on the right
side.
4. Click on the Clone button. If you are prompted about creating a clone of the Recovery HD be
sure to opt for that.
Destination means a freshly erased external backup drive. Source means the internal
startup drive.
Step Two - Prepare the machine for the new buyer:
1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.
2, Remove any Open Firmware passwords or Firmware passwords.
3. Turn the brightness full up and volume nearly so.
4. Turn off File Vault, if enabled.
5. Disable iCloud, if enabled: See.What to do with iCloud before selling your computer
Step Three - Install a fresh OS:
A. Snow Leopard and earlier versions of OS X
1. Insert the original OS X install CD/DVD that came with your computer.
2. Restart the computer while holding down the C key to boot from the CD/DVD.
3. Select Disk Utility from the Utilities menu; repartition and reformat the internal hard drive.
Optionally, click on the Security button and set the Zero Data option to one-pass.
4. Install OS X.
5. Upon completion DO NOT restart the computer.
6. Shutdown the computer.
B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)
Note: You will need an active Internet connection. I suggest using Ethernet if possible because
it is three times faster than wireless.
1. Restart the computer while holding down the COMMAND and R keys until the Mac OS X
Utilities window appears.
2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button.
3. 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.
4. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button
and set the Zero Data option to one-pass.
5. Click on the Erase button and wait until the process has completed.
6. Quit DU and return to the Mac OS X Utilities window.
7. Select Reinstall Lion/Mountain Lion and click on the Install button.
8. Upon completion shutdown the computer.
*If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In the case of the latter you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License.
