Removing my second start up disk

Hello all,
I have two disks on my Macpro, and I have an old Lion (10.7) start up disk installed on the second hard drive that I'd like to remove. Anyone able to break down the steps to remove it?

The best thing to do that is to erase the disk (if it's this what you want). Open Disk Utility, select that Lion partition on the sidebar, go to Erase tab and erase the disk. Finally, that startup disk will disappear.
If you want to mean that your Mac is starting on that partition and you want to start by default on another one, open System Preferences > Startup Disk, and choose another partition

HT201364 How do you remove OSX from start up disk?

Trying to update to OSZ Mavrick and system is telling me that: "You need 4.93 GB of available space to download OS X Mavericks. Remove items from your startup disk to increase available space." How do I accomplish this?

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.
Look through your other Mailboxes and other Mail categories to see If there is other mail you can archive and/or delete.
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!

HT1338 how do i remove items from start up disk to create space for updates

Hello,
i can't update becuase i need to "remove items from my startup_disk? how do i do that? is that the same as my hard_disk?

Yes, your hard disk is your startup disk. How large is your disk and how much space is still available?
How many videos, music, and pics do you have on your disk? You may have to move such space hogging files to an external drive; your startup disk needs an absolute minimum of 10 - 15 GB of free/empty space at all times in order to function properly.

I want to transfer most of my photos from my iPhoto library to my external hard drive. I have been getting the message that my start up disk is almost full. I want to transfer and then remove them from my computer and have them only stored externally.

My start up disk needs more space and I have tons of photos on my computer that I want to transfer to my external hard drive and remove from my computer to free up space. How can I do this and make sure all my photos are still properly saved and transferred. I dont need to transfer my whole iPhoto library just some really old albums.

Here is some help.
https://discussions.apple.com/thread/3849933
After confirming that all your stuff is on the drive, delete the photos you have copied. You will need to empty the iPhototrash to free up the space.

HT201364 I am unable to install OS X Mavericks on my macbook air 13" it asks me to remove items from my start up disk...how do I do that?

How does one remove items in the start up disk....
Thank you

You apparently have filled your boot disk to a point where the remaining space is below Mavericks installation requirements. It is implying that you need to review your login directory for very large files, or folders.
Open a new Finder window. In the left nav, select your short login name. Then change the View to list view. If the Size column arrow is pointing up, click it to down and your folders and files will be listed in descending storage use. The folders with an engraved emblem on them were created by the operating system, so do not remove them. Also, resist removing Apple applications found in /Applications.
Top candidates would be huge iTunes Music or applications content, iPhoto, or video collections. Whatever is taking up your storage will stand out. Generally, you should stay out of your Library folder.

New Mac Mini Server, two Hard drives, Can I install an older Mac OS on the second drive and switch start up disks to run PowerPc applications?

New Mac Mini Server, has two Hard drives, could I install an older Mac OS on the second drive and switch start up disks to run PowerPc applications?

I haven't purchased a Mac Mini at this time and I may not if I can't use it as a non server. I need to update my system I would be better off buying a new Mac with Snow Leopard the last app that will run Rosetta. The Mac Mini Server has a quad 2.0 processor and 4 GB RAM and two internal hard drives and should out perform my dual 1.25 G4. I can run PPC apps on my G4 but it is 8+ years old and seems to be getting noisy. I don't want to tie myself to another old machine. I want a machine that will work with Intel Apps I was hoping that the two hard drives would allow me to boot from the second with Snow Leopard and use Lion on the first drive to be able to keep up to date with all my other universal apps and Mac OS up grades. The application I use the most is my CanvasX app with drawing & vector effects, text & typography, sprite technology, painting, image editing, and multimedia tools are all in this one app but will not be updated to run Intel apps. I am frozen in time because my most valuable Application won't be updated and Apple has cut me off by not supporting PPC in Lion and onward; Apple used to backward support but I guess that they are no longer as user friendly and concerned with a happy user. I have always been a loyal Mac user and I will not migrate to Windows under any circumstance; I hate windows!
Thanks for your prompt response,
Dick Deaton

How do i remove space from my start up disk?

Do you mean "make" space on your HD?
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.

Is it possible to move the files off the start up disk without deleting them?
I would appreciate feedback,

Well you can move them to an external drive but this will delete them from the internal drive. Which is what you have to do to free up disk space.

HT201177 How Do I Remove Files From My Start-Up Disk?

Can someone tell me how to remove files from my start up disk?

Your startup volume is full. First, reboot. That will temporarily free up some space. According to Apple documentation, you need at least 9 GB free for normal operation. You also need enough space left over to allow for growth of your data.
Use a tool such as OmniDiskSweeper to explore your volume and find out what's taking up the space.
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 really see everything, you have to run it as root.
First, back up all data if you haven't already done so. No matter what happens, you should be able to restore your system to the state it was in at the time of that backup.
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.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.
After installing ODS in the Applications folder, drag or copy — do not type — the following line into the Terminal window, then press return:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
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.
I don't recommend that you make a habit of this. Don't delete anything while running ODS as root. When you're done with it, quit it and also quit Terminal.
