Startup disk almost full--how to change the defualt free space amount?

I know that not too long ago I was able to change the default value that OSX uses to determine if the startup disk is almost full (5 GB?). For the life of me, I can't remember how I did that. I do know that it was a simple process--no terminal, no Unix, just a simple dialog box somewhere.
Can anyone remind me how to make this adjustment?

There is no such parameter built-in to OS X. You must have been using some third-party disk monitoring utility.

Startup disk almost full, what are my option

"startup disk almost full"
What are my options for additional space on my startup disk??????
Previously I have copied my photos and documents onto disks to make more space.
I do have lots of program on my computer which I guess is taking up most of the space.
Any help would be greatly appreciated.

Hi deeswaz,
I would download and run WhatSize or OmniDiskSweeper, separately from each User Account, to make sure about some files that may exist somewhere, grown enormously with no reason to keep them on your hard drive.
Also:
Does your periodic maintenance (aka "cron scripts") run regularly enough? If it never ran, your log files too can take a huge space in some cases.
Caches:
You can delete Users caches folders to gain space. Use WhatSize or Finder's Find (⌘F) to locate them and drag them to the Trash.
They will rebuild themselves automatically (experiencing some small, harmless slowdowns sometimes), with nothing but the caches your applications actually use, not the old stuff that you don't use since months.
Other:
Of course the obvious:
Uninstall all that is useless. Did you Custom-Install Mac OS X, with only the printer drivers you need, with not all languages installed etc (keep BSDSubsystem though).
Good luck!

Its saying startup disk almost full. have no music or photos on computer. how do i clear it up and free up the HD

its saying startup disk almost full. have no music or photos on computer. how do i clear it up and free up the HD

There are some items to the right of these reply boxes,
of them a few are likely to be of help to some extent...
Without knowing which OS X version, advice will be not specific
and to answer three different ways when one of them is correct
is a waste of time.
Is your OS X newer than Lion 10.7.5? IF so different rules apply
to finding out what is free space, where it is, & how to tell if it is.
For systems older than Lion (Snow Leopard, Leopard, Tiger, Panther)
the rules are a little different, since there would not be an Other item
on the hard disk drive which could contain items necessary to the OS
yet not detailed to the user.
And Lion 10.7 has a few hidden files that are hard to locate, and one
of them may have some bearing on the missing space of a HDD.
The items here, mostly for 10.7:

https://discussions.apple.com/message/11808734#11808734
There are Support articles, you could use Help viewer in the
system, on your computer, to look for results; or use google.
However, avoid the temptation to use a badware such as cleanmymac,
mackeeper, and others that are sources of known trouble to the Mac.
Good luck & happy computing!

HT3680 My 3 year old iMac is freezing and I get a message "startup disk almost full for running applications. delete files..." Where do I find the startup disk and what should I delete?

My 3 year old Mac is having trouble and freezes up from time to time lately. I get a message saying "startup disk almost full, delete files ..." something about having enough room for applications to function. I know my startup disk is the Macintosh HD, but what kind of files do I need to delete and how much space do I need to free up? In my "about this mac" area, it says I have 4.89gb free out of 319.21 So I am confused why I need to do this.

You're less than 2% free and should always have at least 15% (my SWAG). Best is to get an ext FWHD and move stuff from the startup disk to it and delete it from that. Best things to move are movies, music, and photos, using the apps that manage those things.

"startup disk almost full" message - NOT TRUE! I have about 900 GB of free space. What can I do about this?

I have been getting repeated messages "startup disk almost full". I am on a very new iMac running Lion with the most up to date OS. This is a 1 TB iMac. When I first got the message, I cleaned almost everything but the applications off the disk. I now have more than 900 GB of space but again I am getting the message. I found someone reporting the same problem and he said Apple Care reported a but in the mail system. He found a Fix but it is not working for me. (He clicked the option key and opened finder, then went to Library/mail/mailbox/recovered messages and deleted the recovered messages. But I do not have any folder called "recovered messages" so can't pursue that fix. Any ideas?

I'm don't know about the new systems, but I remember that I set the % full to warn me. Your % might be set to 20% or something rather than 10% which is a preferable safety margin for many uses. I solved this start up disk problem by installing a 2 Tb internal drive and keeping my data files on external, raided, drives. A real show-stopper is when your 45 Tb external drive warns you that you're too close to OUT for comfort. And, Yes, I do keep it trash free.

Startup Disk Almost Full

I went to use my iMac last night and noticed that sometime between the time I last used it that morning to the time I used it in the evening I lost about 50GB and got a "Startup Disk Almost Full" error message. When I did a "Get Info" on the iMac's HD it said zero space available. I rebooted and did everything I could think of to see if it was just a glitch, but it still said zero space available. I ended up using the Leopard Install Disk to restore from a Time Machine Backup that was done about the time I had last used the iMac and somehow came out with 119GB of free space. At the time the back was made my HD had only about 50GB of free space so I am not sure where all the extra space came from. The good news is that it looks like Time Machine did a great job of restoring the Mac and I haven't discovered anything missing, at least so far. The bad news is that I continue to have a lot of problems with Leopard; this being only one minor one. Just wanted to see if anyone else has had this "Disk Almost Full" error and were able to diagnose it.

Thanks. I had already used Time Machine to restore to a previous backup and fixed the problem that way. Next time this happens I will try to figure out what files are consuming all the space and see if that helps me determine the cause of massive memory loss.

Blue screen after login and HD and startup disk is full -how to erase data?

Blue screen after login and Hard drive and startup disk is full -How do I get in to erase data?

this user tip might help:
Your Mac needs adequate hard drive space to operate normally. How full can a drive be before it's too full? There is no hard and fast rule that says “X” amount or “%” of free drive space is needed. A low amount of RAM requires more drive space for Virtual Memory’s swap files.
Problems from insufficient RAM and free hard disk space are discussed in this link
http://www.thexlab.com/faqs/lackofram.html
Here’s some general guidelines for minimum hard drive free space:
1. As a general rule, your available space should be 5GB as an absolute minimum as it generally requires that much free space to perform an Archive and Install of Mac OS X and still preserve some free space for VM swap files.
2. Some say that your hard drive should have at least 5% of it's capacity available for use. Still others say 10% to 15%. If you routinely process complex graphics and videos, even more space is required.
Look at these links about freeing up more space.

How to free up my disk space
http://www.macmaps.com/diskfull.html
JGG

My mac air says " startup disk is full".How to solve ???

My Mac air has a message during starting the computer and says that startup disk if full. In the composition of my hard there are 120 GB used space on other parts, which I have not understand where is these files.

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. 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.
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. That method may not find large folders that contain a lot of small files.
You can more effectively use a tool such as OmniDiskSweeper (ODS) to explore your 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.
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 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. Quit it if it's running.
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 into the Terminal window (command-V). 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.
The application window will open, eventually showing all files in all folders. It may take some minutes for ODS to list all the files.
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 in doubt, leave it alone or ask for guidance.
When you're done with ODS, quit it and also quit Terminal.

Startup disk almost full but cannot log on to delete items

when I start up my MacBook air it said "start up disk almost full" but I cannot even log on my act to get to my home screen to attempt to delete stuff... what do I do?

Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. 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.

I keep getting the message that my startup disk is full, yet I have about 300GB of space left on my HD? Any solutions for fixing this problem?

I keep getting the message that my startup disk is full, yet I have almost 300GB left on my hardrive. I have emptied the trash on my desktop and in iPhoto, and I have removed unnecessary programs. The only way I can get the message to go away is to restart my computer. If I let the computer go to sleep, I get the message back when I start using it again. Any suggestions?

Mountain Lion Recovery
Boot up from your computer by holding down the command+r keys. This will take you to the recovery drive.
Select Disk Utility & hit Return.
In Disk Utility select the HD on the left & click on Repair Disk (bottom right).
=======================
Empty the trash in the Dock as well as iPhoto’s trash!
Open up your application folder & go through all your apps. Trash all the apps you no longer want and/or use.
An easier way to do this is to open the Application folder in list view & press the Command+j keys.
In the the dialog that appears, click the "This Window Only" button & the "Calculate All Sizes" check box.
Wait a bit until your file & folder sizes have all been calculated, then click the "Size" column to sort your apps from the fattest to the most anorexic.
Get rid of all your photo files you don't want and/or need. Same goes for those pics off the websites you downloaded (gifs, jpegs, etc.). Or transfer/move them all to a photo/movie storage site like ImageShack and Photobucket, 2 of the most popular FREE storage sites.
Get rid of all your video & music files you no longer view and/or listen too. Especially, if you already have the actual CD/DVDs or you can later redownload from a website. Or transfer them all to a FREE video/movies and/or music storage site.
Use Spotlight to make sure you got rid of everything. You can even trash directly from Spotlight! Better yet, download this FREE software called Find File. This app puts Spotlight to shame (works w/Mountain Lion).
Drag what you don't want and/or need to the trash. Better yet, download this neat little shareware app *demo* called AppZapper. It basically does all the work for you by not only trashing the apps but the apps preference files, caches & all its associated files.
Another software that does the above is AppDelete. Best of all this software is free!
Burn what you want and/or need onto CDs or DVDs. Not everyone has the luxury of purchasing an external HD and/or the system requirements for iCloud to store their "stuff.”
Dropbox is a free storage utility to check out.
You can check with your ISP to see if they offer *free* storage space. Most if not all do now-a-days. There are thousands if not millions of *free* storage facilities on the web also. Use your favorite search engine to search them out as they come in different storage sizes to fit your needs & wants.
Check for duplicate fonts.
Applications>Font Book
Select “All Fonts”
If you see any “black dots” next to any fonts this mean you have duplicates and/or multiple versions of these fonts.
To clean this up, select a “black dotted” font or the Apple + *click* to select multiple dotted fonts;
Edit>Resolve>Duplicates.
What the above does is turns off the duplicates & multiple version fonts. Not delete them.
More than likely the “extras” were installed by other programs and/or other users.
Clear out font caches
Use FontNuke. It does all the work for you. And, best of all it’s *FREE*.
Printer Drivers
Get rid of all the printer drivers you don’t need & use except the ones for your *current* printer(s)/scanner(s).
HD>Library>Printers Folder
If you accidently threw something out that you needed for your printer/scanner it can be easily obtained from the manufacturer’s website and/or from the CD that came w/the printer/scanner.
Garage Band
Has about 1GB of loops stored. Get rid of some some them. You surely don’t use, like and/or need them all.
HD>Library>Audio/Apple Loops>Apple>Apple Loops For GarageBand
Or just get rid of the Garage Band app altogether if you don’t use it.
Get rid of extra languages
Strip your computer down to your “native” tongue.
You can do this with a *FREE* utility called Monolingual. Another app that apparently does all the work for you. I’ve never used it. However, a lot of users here swear by & recommend it highly.
However, there is a warning for *native English speakers*. Make sure you keep BOTH English and English (United States).

IMovie: "startup disk almost full..."

but I currently have 221GB free on my hard drive. I realise there are other threads regarding this error, but they all seem to involve people whose disks are actually full. Mine, as indicated in Disk Utility, has 221GB available. This error only occurs when using iMovie. I am not working with HD video or doing anything really intense. I am running the MacBook Pro Retina (2012). This error has been occurring from the beginning and I've finally grown tired of it and decided to seek some answers. There's no reasonable explanation that using a stock native piece of software on Apple's premier notebook should be an issue. I don't know what I could do differently. I don't have any other applications running while iMovie is open.
Thanks!

Well, I am back in hopes that SOMEONE has respnded to this. I guess it's just me. I see literally hundreds of threads on here about the startup disk being full and everyone just assumes that they guy posting is a complete idiot. This message is appearing in ERROR. As I stated, I recently wiped, formatted, and installed a fresh OSX on my 2012 Retina. Upon starting iMovie for the first time, I got the same message I had always seen, "Startup Disk is Almost Full". I double checked my hard drive usage and confirmed that I still had 221GB free. 221GB free.
221GB of unused space on the disk.
221GB of unused space on the disk.
There are 221GB of free space on my startup disk.
My startup disk is NOT almost full, as more than half of it is empty, leaving 221GB unused. To put it another way, my hard drive currently has 221GB of unused space. As it stands today, 221GB of my startup disk are available for new data. When I start iMovie, an error comes up telling me that my startup disk is almost full but there is 221GB of open space on the disk.
In case I failed to clearly state the problem, my hard drive is more than half empty - 221GB free - and iMovie tells me its almost full.

My startup disk is full: how do I clean it up? Simply deleting some files does not help.

I get the message that my startup disk is full. It says to delete some files to make more space; but after deleting some files, this message will reappear again after a while. What else can be done?

I hope you haven't removed anything that involves the system.
I hope you haven't remove things willy nilly, either.
Here are some general tips to keep your Mac's hard drive trim and slim as possible
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.
To find other large files, download an app called Omni Disk Sweeper.
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 startup disk is full, how do I Repair it

I have a iMac and a macBook. Both are displaying a message that the startup disk is full. I would like to fix this problem, but I’m afraid that I might do more damage then good. Is there anyone that can walk me through it so that when I’m done I don’t have to take them into the apple store because I messed them up more..
Thanks,

Maybe it would be a good idea to have someone do this for you, but if you really want to do it, then
1. Make sure you are logged into an account which does NOT have admin rights. Just in case you try to do bad things to important system files, this will stop you. If you get a message saying you have to put in an admin's userid and password, you are probably trying to do bad things. Don't do it!
2. Take backups of what you have. You do have a good multi-method backup regime, don't you?
3. Look for data which you truly don't want, and never will, and delete it. Empty the trash.
4. If you now have enough free space on your boot disk (say 20%), then you are nearly done, but not quite
5. If you couldn't find enough files and folders to trash, then decide which you'd be happy to move to an external drive. Copy them there (not to one of your backup drives, please!), and trash the copy on the boot drive
6. When you have reduced the clutter on the boot drive and have a good lot of free space, then you have one remaining problem. Since the drives got to be nearly full, you will probably have caused bad fragmentation of your boot drive files and free space. Either use a defrag program or make a clone copy of the boot drive, boot from the clone and clone back to the internal drive, then boot from it. Make sure you always have a good backup or two along the way. Consider upgrading the capacity of the boot drives during this process.

Why is my Macbook pro with OS lion prompting me my startup disk almost full when i have deleted many files, photos and videos? Even thrashing them doesn't help. There seems to be an automatic space usage in the background

I have deleted many unwanted files and apps and yet the available space keeps depleting every time i am using my Macbook Pro. I believe under the OS 10.7.4 one of the features is it backups or has backgrounding features which uses memory. Sometimes even when i hv 8GB space after using my Macbook Pro for say 2hrs surfing internet and using Pages which has a "Save Version" feature suddenly my 8GB goes down to 300+MB only and it starts prompting me "My Startup Disk is almost full" once it reaches 1GB space left. How can i get more space.... Please someone can help me? Do i need to re-format my hardisk??!! Any help out there is greatly appreciated.
My original HD is 320GB. And i don't hv too many Apps installed. I do have abt 50-70apps. I do have many photos and videos stored in iPhoto's Library though.

One thing I've noticed is that a shared tab pops up when I open the finder under "favorites" with a random connection. It's called hp68b... None of my friends that I live with have this and we all use the same internet. Two days ago when I would click it and click get info, it said it was a pc. When I checked it today it said it is a "sharepoint" and looks like a harddrive.
I took it too the store after i spilt water on it but when I got it back it ran perfectly fine. I don't know a lot about computer so if somebody could help me. It says I'm connected to it and I can't disconnect or delete it. I don't know if the guy at the computer store put something in my computer and is sharing all my files.
