Where did the startup disk for Time Machine go?????

The icon is not under devices or on desktop. When I clicked the circle with exclamation mark in the center on menu bar it indicated TM is turned on. I get the message that startup disk cannot be found. If you can help, please explain in a way that someone (me) who is not a "techie" can understand.
Thanks,
Sharon

I appreciate your help. After doing that still nothing happened so I changed the power source and now it is working again. I added a big surge protector power strip, before I must have had too many things plugged to the in-wall adapter.
Thanks,

What is the startup disk that the iMac says is full?

Where is the startup disk and how can I access it to delete files.

Do a search for and downlaod and install OmniDisk Sweeper and OnyX.
Hard drive getting full or near full?
Here are some of my tips for deleting or archiving data off of your internal hard
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 use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Other things you can do to gain space.
Delete any old or no longer needed emails and/or archive older emails you want to save to disc, Flash drive/s or to ext. hard drive.
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, Flash drive or ext. hard drive and/or delete any old documents you no longer use or immediately need.
Uninstall apps that you no longer use. If the app has a dedicated uninstaller, use it to completely uninstall the app. If the app has no uninstaller, then just drag it to the OS X Trash icon and empty the Trash.
Also, if you save old downloaded .dmg application installer files, you can either archive and delete these or just delete the ones you think you'll never install, again.
Download an app called OnyX for your version of OS X.
When you install and launch it, let it do its thing initially, then go to the cleaning and maintenance tabs and run all of the processes in the tabs. 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.
If you have any other large folders of personal data or projects, these should be thinned out, moved, also, to the external hard drive and then either archived to disc, Flash drive or ext. hard drive and/or deleted off your internal hard drive.
Good Luck!

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.

You 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.

I RECEIVE MASAGE THAT TARTUP DISK IS FULL. KINDLY ASSIST WITH HOW TO DECONGEST THE STARTUP DISK OR OTHER OPTIONS?

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.

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."

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.

Trying to get rid of error "The startup disk cannot be partitioned or restored to a single partition". Recovery HD visible.

Hello,
I've been stuck for some hours now trying different things to install Windows 7 on my Macbook Air, and I think now is the time to call for some custom help.
I'm using OS X 10.9.5 Mavericks.
So some months ago I just wanted to run Linux on my laptop so I installed rEFInd, shrunk the Macintosh HD partition by 25GB and booted on a linux live USB flash I burned using dd.
Then I used gparted to create my linux partitions.
It worked just fine, even though disk utility from OS X seemed quite unhappy about this (it seemed to have incorrect informations about the filesystem on these partitions, seeing them as journaled Mac OS while they were clearly not). At this point already, the Recovery HD from mac showed up in disk utility, which I found weird but didn't bother me.
But recently I needed windows on my Mac. So after a few tries for the triple boot, I managed to create a bootable USB stick with boot camp, which already showed me the message "The startup disk cannot be partitioned or restored to a single partition" and hence refused to partition/install himself.
So I thought "OK, that's no big issue, I can just partition with disk utility and then boot on the USB stick and everything will work fine". But when EFI booting on the USB flash drive I got stuck at the beginning of Windows installer with no keyboard or mouse support.
After some hours spent googling, I was unable to find a working fix for that, and as there was no support for my case (where I used bootcamp to create the bootable flash but NOT to partition/reboot) I decided to give bootcamp a try.
So I erased my linux partitions, and cleaned up everything I could on the HD with disk utility. That means I now have two partitions showing in disk utility : Macintosh HD and Recovery HD.
When using disk utility from terminal, the list is :
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *121.3 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:                  Apple_HFS Macintosh HD            80.0 GB    disk0s2
   3:                  Apple_HFS Recovery HD             650.1 MB   disk0s3
But boot camp still isn't happy, and the message "The startup disk cannot be partitioned or restored to a single partition" keeps popping after the intro and I can't partition/boot from bootcamp.
So, as I don't understand what is wrong here anymore, any help would be greatly appreciated!
I will be watching the thread a lot because I really would like this resolved (or windows installed one way or another) this weekend; so any questions on my past manipulations or config just ask!
Thank you.

keyboard issues are also something of a common issue.
I wish the best threads were voted to the top of forums, something! Me, I literally burned out here, but after installing 10 Preview, wanted to "see what was going on" after hiatus of a couple years and see if anything had changed (no, not really!)
Also, these new Communities are not putting "more like this" and failing to help too.
I think rewriting Boot Camp Assistant's built in help and pdf would help a lot, and needs to be clearer and go into details. And Yosemite was not it seems tested against Boot Camp, and drivers for new Macs + new OS also lag behind. Again, common and no sign of improvement or change.
One of the tricks to the "can't partition" is rather simple - of course backup is step #1 and is spelled out - SHRINK the main HFS+ partition! then stretch it back to full length. Sometimes a reboot is needed, and sometimes even do a Safe Boot - not sure what but Recovry Mode might be a good option too. That does seem to consolidate free space, move files that are locked and cannot be moved otherwise, and allow BCA to partition, jusst be sure to have enough space left and large enough for a proper Windows install (and fudge factor).

The startup disk can't be used as a restore source

Dear,
can anybody tell, whenver i tried to clone (thru disk utility using firwire cable ) my macbookpro with imac (latest one), it shows me the folloing information/error
i.e.
The startup disk can’t be used as a restore source.
To use this disk as a source, restart your computer using the recovery system, and open Disk Utility again.
Followed the below steps_________________________
Disk Utility> Selected HDD > Restore (tab) > drag hdd to SOURCE (it is my MBP) > dragged hdd to DESTINATION (it is iMac) > Restore
Looking your reply.
Regards

Are you trying to copy the OSX drive from a MacBookPro to an iMac? If so, be glad it won't let you. Most likely, it won't run at all; if it does, all sorts of things will go wrong.
What are you trying to do? If you're trying to set one Mac up like another one, see How do I set up a new Mac from an old one, its backups, or a PC?

I think as drive capacities increase, the old 10-15% becomes less accurate. The amount of free space you need doesn't really have anything to do with the drive size. So, increasing your drive size shouldn't mean that you need to have more free GB (which using a % of drive space would mean). You need free space to accommodate page outs (the amount of which would depend on how much RAM you have installed and how memory intensive the applications are), sleep images (again, this would max out at your total amount of RAM), and a bit to minimize fragmentation.
With desktop drives commonly in the 2TB range today, it is certainly not necessary to have 200GB+ free in order to maintain proper operation. I generally find about 30GB to be the minimum I'm comfortable with. Mind you, I pretty much always have way more than that available. But, if I'm working on a system and the amount of free space is at least 30GB, I would generally not site drive space as the cause of any performance issues. I'd say that 30GB is a minimum for a stable system (with 8GB or RAM installed). Of course at that amount, you would still need to free up space if you were to want to install or download any significant amount of data.
With servers being more likely to run into the 16GB of RAM range, more storage would be necessary. Most servers should be well stocked with storage, but the actual needs would vary greatly depending on what's being "served".
The 10-15% thing came about when we used to talk about drive capacities in hundreds of MBs and RAM in terms of KB (not MB and certainly not GB). More drive space is always a good thing, but as drive capacities continue to sky rocket, we don't need to dedicate larger amounts of storage on systems with the same specifications. A set amount of space is required for proper operation regardless of the capacity of the drive installed.

What is OTHERS mean under the startup disk category???

Hello guys, I am facing troubles with the Startup disk. I am getting the message that says " your start up disk is full"...this is not the case, the problems is the category OTHER, i could not find which files goes under that ?? the other categories such as photos, and movies are clear.
I want to know what kind of files goes under category OTHERS so i find them and ears them.
Pleas help...

Grand perspective is fine. But why does every progressive update of Ios make it more difficult to execute such regular maintainence/ why should i have to download a second party piece of software and sit through a long scan just to find the "other" files that are suddenly filling my hard drive? I freed up to 60 GB three weeks ago and now I'm down to 4GB. Since they were the likely suspect, I deleted my iphone and ipad back-ups. I deleted them all because I couldn't figure out on lion how to delete the latest ones. still only got back 8 GB. Something unexplainable is eating all my disc space and it should be easier to find it. Maybe the "it just works" motto has finally crossed into PC micro management lunacy.
