Removing OS9 system folder

I want to delete my OS9 system folder. I don't use, don't want to use and have no need to use it. I have been on OS 10 full time since the 10.1.5 days - I'm not looking back now.
I want to free up some space as this is on my laptop. I know there are other ways, removing languages etc - these have been done. I want to do this but everytime I try I get "The operation cannot be completed because item "System Folder" is required by the System." - when dragging to the trash.
I have changed the owner of the folder to my admin user - no luck. I have tried changing the name of the folder - no luck. What do I need to do? I wan't system 9 gone!

Thanks to Abe, your link provided the answer I needed. Copied below for reference:
Try running the following command in the Terminal:
sudo rm -R /System\ Folder
It will ask for your password. Type it in and hit return. That should delete the OS 9 System Folder.
This was critical because no matter what I did in terms of permissions (as noted in my original post) could I delete the folder OR any of the files inside it (an old OS9 trick where deleting files inside a folder, then the folder itself often worked).

  • How do I install OS9 system folder on an eMac?

    I have a brand new eMac. It has OS 10.4.4 installed. I need to install an OS9 system folder in order to run Classic. I have an OS9 CD, but the eMac can't boot to it or run anything from the cd from OSX. The eMac didnt come with a CD that says anything like additional software or Classic Support. I tried booting to the OSX install CD's and doing a customized install. Classic support or OS9 was not an option.
    Any ideas?

    No new Macs can boot in OS 9, which is half the reason Classic was invented to emulate 9 while your Mac is booted in X.
    The disk set that came with your eMac does contain installers that will give you a System Folder for use with Classic over X, but not on the main disks…
    It's probably on one labelled Additional Software and Mac OS 9 but sorry, these things change from time to time and I haven't seen a recent eMac…

  • Deleting OS9 System folder

    Is it safe to trash the OS9 system folder after upgrading to Leopard? I know that OS9 is no longer supported and the applications will not work. I want to make more room on my hard drive if it is safe to delete. If so, any particulars, or can I just drag it to the trash?

    Thank Dave! Appreciate the speedy response.

  • Removing Previous Systems Folder after Leopard upgrade....Receipts get lost

    After archive and install of Leopard I noticed the "Previous Systems" folder which also happens to contain ALL the receipts from Tiger days. It's over 3GB and I temporarily moved it to an ext hd. Is this OK??? I'm wondering how future update notifications will be handled if old receipts can't be found.
    If I need to move the receipts back to my sys hd do I have to move all the other folders in Previous Systems folder back too, or just Receipts?

    jimbo60640 wrote:
    I thought future installers need to see these (old) receipts to determine update versions.
    Yes, but the installer only needs to see 1 previous receipt not all of them. (i.e. once you have a receipt for 10.5 you no longer need all the receipts for 10.4). The receipts you will need have been copied to your receipt folder.

  • Removing OS9 from the operating system

    My emac is running 10.3.9. I have a 1 GHz power PC G4. I have a 1GB Sdram with a 60 Gb hard drive that only has 5.5 Gb left of usable space. Can I remove the 2 folders in the mac hard drive that contain
    the desktop OS9 and applications OS9 without causing major problems? I need to free up more space so the computer will work faster and I can upgrade the system software to a least 10.4.11. Any suggestions please? Julia

    My OS9 system folder is only ~250MB. Unless your OS9 applications folder is really stuffed, I don't think you'd gain much by removing either. You need to free up several gig and I imagine that evicting the OS9 stuff would gain you less than a gig.
    It's more likely that some other folder is hogging your space. Look at this article:
    http://thexlab.com/faqs/freeingspace.html
    for suggestions on finding what's taking up space and what can be safely removed.

  • Classic will not recognize system folder

    I have installed Classic from the cd that came with my computer. The system folder for os9 shows up in root next to the osx folder, but there is no 9 on the folder. When I try to run classic in system preferences, it says os9 is not installed. I've seen other postings saying to "bless" it by dragging the finder from the os9 system folder to the desktop then back again, but this does nothing.
    Any help would be greatly appreciated!!!

    Hello berne04,
    Did you try this (from the link that Texas Mac Man posted)? Try it instead of dragging and dropping the Finder.
    No "blessed" Mac OS 9 System Folder
    If Classic doesn't start, but Mac OS 9 is installed, the System Folder may not be "blessed".
    Open System Preferences and choose Classic from the View menu. You may see an alert box with the message:
    "No startup volume: There is no volume with a system folder that supports starting Classic. Please install Mac OS 9.1 or later."
    It may not be necessary to reinstall Mac OS 9. Try these steps:
    1. From the Apple menu, choose System Preferences.
    2. From the View menu, choose Startup Disk. The Startup Disk pane appears.
    3. Note the current Startup Disk selection, which is a Mac OS X volume.
    4. Click the Mac OS 9 System Folder you want to bless.
    5. From the View menu, choose Show All.
    6. From the View menu, choose Startup Disk.
    7. Reselect the volume you noted in Step 3.
    8. From the View menu, choose Show All.
    9. Quit System Preferences.
    Hope This Helps,

  • Do I need System Folder to run Classic in 10.4.6?

    I've just bought a new MacBook Pro last night, and in the process of transferring data from my old PowerBook via FireWire connection (the automatic way) it created a number of folders that said "[title of folder] (from old Mac)". In nearly every case, this was accompanied by another folder without the "(from old Mac)" text. One that was only from the old Mac was the OS9 System Folder. Do I even need it, or is all the code necessary to run Classic embedded in 10.4.6?
    Thanks in advance!

  • Question about Removing Permissions from the System Folder with chmod

    Hi
    I have a question about the removal of permissions from the System folder (and sub directories and files).
    Background
    Since installing a new HD, clean install of 10.6, application of updates and moving over backed up user directories I have had several issues with permissions.
    I have read several threads on this and using disk warrior and other tools I have been able to fix most of the issues.
    The Problem
    The issue that remains is a permissions check using Disk Utility keeps reporting
    ACL found but not expected on "System".
    followed by an extensive list of sub directories and all.
    Attempts to repair take hours and the same errors are reported.
    Found Solutions
    I have read about changing and/or completely removing the ACL from the permissions from the System using two different commands:
    sudo chmod -R -N ./System/* ( to remove all ACLs)
    or
    sudo chmod -R -E ./System/* ( to replace all ACLs )
    My Question is ( to the UNIX gurus):
    What is the difference between the usage with -E and -R and which is the best approach for a Systems directory and (subordinates)?
    Many thanks!!

    OK
    So I misread on the your instructions about the PW reset, did it, no harm in that. I did also select the options to reset all the permissions for all the accounts and the ACL issues were not resolved. My bad, I forgot to note that.
    You do suggest getting and expert opinion but alas these are rather elusive. In most cases the Apple solutions is to do a complete reinstall... I have found that unless you completely wipe a drive and rebuild everything there are often artifacts left behind. Since I have full and redundant back-ups I would rather explore and hack a little instead of a dull old system reinstall. The irony is the system issue I had was it was the result a reinstall and combo update on a new drive. I recognize the risks of entering the realms of the System folders but I am willing to explore knowing full well that I have a path to recovery.
    Thanks again for your insights. I come to the forums looking for insights and ideas but not a lecture...

  • How do I install all my old programs and data from an old system folder after I have reinstalled the same OSX system after a crash?

    The system is OSX10.5.8 Leopard on a 2009 imac. A new system was installed from the installation disks and the original system saved to a folder.
    I need to use my Adobe programs, rescue my email, i-tunes and iphoto data.  The disk utility indicates that my Time Machine back-up disk is damaged and I don't want to take a risk of having Time Machine erase my hard drive and try to reinstall the exact system existing at the time of the crash.  There was over 650 gb of stored files that I was copying and removing from the drive at the time it crashed. The total size of the original system file is still about 650 Gb.
    I would prefer to go back in Time Machine and only rescue the programs as most of the files have been copied to external hard drives, but I can't access the back-up hard drive from the new version of the Time Machine.  Or by I don't want the Time Mchine to start copying the new operating system which would include all the data in the old system file. Time Machine was working fine at the time of the crash.

    No, the disk was backed up with time machine a few hours prior to the crash.  I was unable to open the computer when I tried to restart it- got a grey screen with the spinning disk- after a few minutes the screen would go black and would reboot continuously, but not load any images or programs. I started the computer from the 10.5.4 installation disks and checked both the time machine external hard drive and the Imac internal drive with the disk utilities. Both showed as damaged --the internal drive and permissions were repaired, but the external drive (time machine back-up)  was damaged and not repairable by disk utilities. I don't believe that the external drive for Time Machine was connected to the computer at the time of the crash as I was copying files to a different hard drive drive. And I was not having any problems with the TM back-up drive prior to the crash.
    I accessed the Imac internal disk by firewire (as a target disk) and copied as many data files as I had room for on my external hard drives available.  And I deleted quite a few files from the imac internal drive (mostly just jpegs, duplicate tifs, etc--nothing that was used by i-photos, i-tunes or the Mail program).
    Then I installed a new OSX10.5.4 system from the installation disk and the old system was moved to a folder on the hard drive.  I previousy had had the option to reinstall the complete system from Time Machine when I connected that drive and booted with the installation disks with the C key depressed.  But it didn't seem like a good option because I was unsure of the condition of that external disk and whether it would be able to reinstall my data correctly, once it had erased my internal hard drive. 
    I'm considering buying some new external hard drives and backing up the present system to time Machine (so I'll still have my old data in the old system folder).  And then I would try using the old Time Machine back-up to try to reinstall the sytem previous to the crash.  That back-up would reinstall about 700gb of data and operating software and programs which sounds like a lengthy back-up.  Since I have never used Time Machine to do a full reinstallation (I've only used it for individual files), I'm reluctant to do anything rash.
    I'm a professional designer (with a deadline) but I can still use my Illustrator and Photoshop by opening them from the old system folder and saving the files to an external drive.  So it's not neccessary to do anything hasty except to delete some of the excess art and document files that were causing the computer to run slowly and the  Adobe programs to crash when I tried to save my work. I have quite a few books on tape in the i-tumes folder which is probably talking up tons of space but I don't where the i-tunes files live.
    Thanks for any help. Peggy

  • OS 9.2.2 system folder not recognised in tiger

    Hi,
    I'm a bit lost here. I'm trying to get Classic to run in OS X 10.4.11. which has no previous copy of OS9 on it. The OS X was a clean install.
    I installed a copy of OS9.1 onto a USB dongle and then managed to boot the G3 through this and install OS 9.2.1 and then 9.2.2. It had to be installed on the dongle so that I could boot the iMac into OS9 and then install the updates.
    Now, when I start Classic from System Preferences it will find the OS 9.2.2 system folder on the dongle and quite happily run, but it is obviously a lot slower than if the system folder was on the OS X HD.
    So I copied the contents of the USB dongle to the root of the OS X HD and now it will not find the folder.
    Do I need to do anything to enable the OS9 folder now it is on my hard disk. I thought maybe the disk is formatted differently if it is set up exclusively for OS X when carrying out a clean install.
    Interestingly, the machine found my OS9.1 system folder on the HD and tried to run Classic from that, but it just hung on start-up which is a known error between OS 9.1 and Tiger - Hence why I updated from 9.1 to 9.2.2

    Don't worry. I've managed to resolve it.
    I restored my OS9.1 system folder and then copied the contents of the 9.2.2 folder into this. Classic picked it up and work fine.
    The only problem is that now I have discovered that iMovie 2 is not supported in a Classic environment. That was the only reason I was attempting this anyway.
    Oh well....

  • Want to make a backup of system folder/start up disk

    I have a PowerBook 4 that just gave me a start up scare.  Things are working well again, but I realize that I need a back up plan.
    It is running 10.4.11 and has had several upgrades to the hard drive and os, so nothing is original and I do not have original install disks.  All the other computers we have are Intel with newer OS so they are not helpful as start up drives.  And, the DVD drive does not work anymore so none of the OS disks I have are useful.
    But I would like to make a back up of the start up software or system folder in case I ever have a start up problem again.  I understand I could put a start up folder on a Fire Wire Drive and use that to start in target mode.  But I don't know how to make that file, any ideas?  Seems like when we were in System 9 you could just make a copy of the system folder.
    Thanks for any tips!

    Basic Backup
    Get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
    Carbon Copy Cloner
    Data Backup
    Deja Vu
    SuperDuper!
    Synk Pro
    Tri-Backup
    Visit The XLab FAQs and read the FAQ on backup and restore.  Also read How to Back Up and Restore Your Files.
    Although you can buy a complete external drive system, you can also put one together if you are so inclined.  It's relatively easy and only requires a Phillips head screwdriver (typically.)  You can purchase hard drives separately.  This gives you an opportunity to shop for the best prices on a hard drive of your choice.  Reliable brands include Seagate, Hitachi, Western Digital, Toshiba, and Fujitsu.  You can find reviews and benchmarks on many drives at Storage Review.
    Enclosures for FireWire and USB are readily available.  You can find only FireWire enclosures, only USB enclosures, and enclosures that feature multiple ports.  I would stress getting enclosures that use the Oxford chipsets especially for Firewire drives (911, 921, 922, for example.)  You can find enclosures at places such as;
    Cool Drives
    OWC
    WiebeTech
    Firewire Direct
    California Drives
    NewEgg
    All you need do is remove a case cover, mount the hard drive in the enclosure and connect the cables, then re-attach the case cover.  Usually the only tool required is a small or medium Phillips screwdriver.

  • Is it possible to reinstall Symbol dfont into the system folder?

    Since updating to Snow Leopard, there is no Symbol dfont in the system folder. I have been relying on this font for sometime now to avoid special character issues.
    I use InDesign and this font has become essential for my work. The Symbol font now supplied with the OSX ver.6 (Symbol.ttf) is noticeably different.
    Is there a way of reloading Symbol dfont into the system folder without it becoming a nightmare? Or, can I replace the current Symbol font?

    This is one of those infamous Apple "invisible" fonts that are not removable.
    Other than those in the ProtectedFonts folder (not invisible, just difficult to find), their are no "invisible" fonts on the hard drive.
    The only Symbol font installed by Snow Leopard is the Symbol.ttf font in the /System/Library/Fonts/ folder.
    You can try removing it, and it will seem to go away, but somehow it keeps showing up.
    What did you do after removing it? How did you remove it?
    If you simply dragged it to the trash, that won't work. Only a copy of the font will go in the trash, or desktop, or wherever you drag it. To delete any font from the System folder, you must choose Delete and enter your admin password.
    After that, it's still not gone. Even in the trash, any font from the System folder remains active (you can't even empty the trash) until you at least restart the Mac.
    You may still have issues after installing Symbol.dfont from Leopard if the OS, or applications use the cached data for the .ttf version instead of creating fresh data for the replacement font.
    Close all running applications. From an administrator account, open the Terminal app and enter the following command. You can also copy/paste it from here into the Terminal window:
    sudo atsutil databases -remove
    This removes all font cache files. Both for the system and all user font cache files. After running the command, close Terminal and immediately restart your Mac.
    Once the Snow Leopard version of Symbol is truly off the drive, you should have no trouble using the .dfont version from Leopard.

  • Do I need OS 9 System Folder and Applications?

    I am running low on space and am looking at things to remove from my internal hard drive. Is there any risk to removing the OS 9 folders? I have a 200G external harddrive with lots of space. Is moving the folders there a better option than deleting them or does moving them cause problems also if I might need them in the future?
    Thanks,

    powerbook   Mac OS X (10.3.9)   12 in

    Hi, asinhk. The disk space you'd regain by deleting your OS 9 System Folder and Applications Folder is likely to be less, maybe far less, than one gigabyte. Check the sizes of those folders using the Finder's Get Info command to see how much space you're actually talking about.
    If you have no need at all to run Classic applications — you never do so in your day-to-day work, and you have no old, stored documents that you'll ever need to access in Classic mode — then you can safely delete OS 9 and its applications. It would also be OK to transfer the two major OS 9-related folders to your external drive, if you do need to run Classic sometimes, and if you'll have the external drive connected to the Powerbook whenever you need to use Classic. If you do that, you'll need to re-specify the new location of the System Folder to use for Classic in the Classic pane of System Preferences.
    But ultimately, if you are so pressed for hard drive space that removing OS 9 from your internal drive is going to make any significant difference, then you'll need a new, larger internal hard drive very soon even if you do delete OS 9. If you ever need to perform an Archive & Install of OS X, or you ever want to burn a DVD, you'll need at least 5GB of available space on your internal hard drive to do so. If you can't free up that much space on your HD right now without making agonizing choices about what to keep, you already need a bigger drive.
