How downgrade of the el capitan to snow leopard with sl dvd on imac installation 2011

thinking about sl 10.6.8 level to el capitan on imac 2011.

I would like to know before the upgrade if there is no safe mode to downgrade again if I don't like el capitan. I have the original SL DVD´S that comes with the mac.

Thank´s.

Unless you want to lose all backup now. Then wipe the drive and install SL, recover your files in the backup.

  • Compatibility CD Snow Leopard with El Capitan

    Hello

    Until recently, I used the (installed via the original CD) on a plain Macbook snow leopard, and subsequently, I installed Windows XP SP3 via Bootcamp. I remember that after the installation I had to install utilities Bootcamp from the original CD of Snow Leopard.

    A few weeks ago, I upgraded to El Capitan, and then to Windows 7 in the original Bootcamp partition. Are there specific utilities of Bootcamp I should install?

    In which case the answer is Yes, where can I find/download utilities for editing?

    Thanks for the advice.

    Hi
     
    Yep, use Index Array as Gerd says. Also, using the context help ( + h) and looking through the array palette will help you get an understanding of what each VI does.
     
    This is fundamental LabVIEW stuff, perhaps you'd be better spending some time going through the basics.

  • Re-install Snow Leopard to a notice of Imac I3 mid-2010?

    Hello

    I have already received some good answers in another thread, but it had a different title, so I thought that I post here and maybe some members will more experience with this:

    I just bought a used Imac which is currently being shipped to me.  Here are the specs: mid-2010 21.5 inches screen, model A1311, series: W8114294DAS, Intel Core I3 3.06 ghz processor.

    He will come running to El Capitan, but they advised me to wipe the drive and reinstall the original operating system, which is the snow leopard, and then upgrade from there to El Capitan, with my own Apple ID. However, it seems to be difficult with this particular model. If the computer is initially supplied with Snow Leopard 10.6.4. My drive of detail might not work for the re - install.  I was told that Apple would be able to ship me a custom. I've also read about yet another thread that maybe these models came with a slightly different version of Snow Leopard, and this is why the retail CD may not work, even if the computer came with version 10.6.3. and it would be better to get a custom. Is this true?

    Then there may be a problem with an update of the firmware that the computer may or may not have and which could cause problems (not allow Snow Leopard install at all, or instead to install Lion). Is it possible to say if he had this update and maybe disable it before attempting to erase and install Snow Leopard?

    Does anyone have advice/stories to share before I actually try it? Or what would be the best way to go about this? I thought that I would try my SL CD detail first, and I hope that it will work. Otherwise, I could order the CD on measure and try this one. If I can't erase, at least I didn't damage, but what happens if I erase the disc, but then failed to install Snow Leopard? I was left with a blank computer. Or I would be able to install it once the disc has been erased?

    Someone also said using SuperDuper may erase the disc elsewhere or at least to make a back-up? I have not used before. There is no personal information on the computer again, I would try to re - install before anything else, so I just need a way to install El Capitan under my Apple ID, then I'll be able to install updates, or even a new operating system, as it becomes available.

    Is there a risk to try to use my SL CD detail if it allows me to erase and install (such as the installation of the 'wrong' version of Snow Leopard)?

    Here is the link to the original thread: purchases used Imac tips?

    Thanks for any idea!

    You can try this much easier.

    1 - Connect to App store with your apple ID.

    2 - install download 10.11 - he will say that you have already installed just 10.11 to proceed.

    3. create a usb installation program.

    4 - start the installer - erase hard drive and install a clean copy of 10.11

    5. place the iMac with your apple ID.

  • With the help of a Snow Leopard bootable or hard disk drive

    When I upgraded my MacBook Pro to Snow Leopard to El Capitan, I have also created a disk external drive bootable that would go SL. There are a few applications would not run on the CBS.

    Is there a way to get around this?

  • Empty contacts after upgrade to El Capitan in Snow Leopard

    Hi-

    Naively I upgraded my MacBook Pro to Snow Leopard (10.6.8) to El Capitan (10.11.1) just above my internal drive, so going back is not an option. I guess I could wipe my drive, install 10.6.8 then restore from a week ago with Time Machine.  (The same backup drive is used under the two systems).  But I'd rather have work 10.11.

    A problem is disappeared from my address book and here this new application of Contacts has a similar icon but no contact.  I read in the help that I could restore from a backup of the address book, but I have an extraordinary before the transition.

    What should do?  Any ideas?

  • C5180 scanning and copying the black leaves after Snow Leopard upgrade

    the machine prints since Mac perfectly, if there is a little bit slower than before starting and not offering is not the same features, even through an excerpt.

    However, scan and copy are leaves only in black.

    I made the suggested HP set again which did not improve anything; I looked at downloads of diagnoses, but they do not say that it is compatible with Mac.

    Is this problem one leopard snow associated one or is - just that the C5180 is dead?  If it's the snow leopard, can anyone advise me on how to fix it?

    If the copy does not work from the front panel, then your scanner is dead.  I'm sorry.

  • How to set the power settings - Satellite Pro A10 with Win XP Pro

    I an A10 Pro of the Satellite with Win XP Pro installed and cannot access the power settings. When I go into the power settings in Windows, I get a msg telling me to use Toshiba Power Saver and Win power settings are grayed out.
    I installed pwrsav-spa10-xp-60007-.zip which tells me that it is installing the Toshiba Power Saver, but always Win power settings are greyed out and I can't find no separate application "Toshiba Power Saver".
    The BIOS shows ' version of BIOS ACPI = 1.30.
    Can someone advice how to change the power settings please?
    Thnx.

    Dave

    Hi Dave,.

    You have the "Toshiba common Modules" installed? They must first of all for many models of Toshiba, and power settings module is an add-on for that.

    If you do not have the appropriate restoration or the utility CD handy, the drivers can be downloaded from the Web from Toshiba website.

    I hope this helps, let us know how you go

  • How to read the status of User1 DIP-switch with a cRIO FPGA chassis?

    How to read the State of the DIP switches on a FPGA cRio chassis?

    I work with a cRIO 9022... My idea is to put the system in "service" mode with USER1 switch to IT and communicate with the FPGA via the FPGA - GUI (VI) on the host computer instead via the RT module that is used in normal conditions.

    Any ideas? Unfortunately, I don't have an unused channel on the left... .and (as I know) cannot use the interface RS232 of FPGA.

    Many thanks in advance,

    Luke

    Hi, this is the correct information. You cannot read the FPGA of DIP-switch status. The only thing you could do is to use the function of Reading Switch.vi located under the range of functions-> real-> utilities RT time

    It's how you probably know side host RT and not the FPGA.
