How to go back from 10.4.5 - 10.4.2?

Upgrading to 10.4.5 broke a scientific application I rely on. How can one go back to an earlier version of OS X? That's not something I've ever tried to do.
I have a full backup, but not that far back.

You will need to reinstall the older version by doing an Archive and Install to avoid having to erase the hard drive. Before doing an Archive and Install you should first repair the hard drive. Do not attempt an Archive and Install until the hard drive has been verified as OK.
Obviously if you can erase the hard drive than boot from the older version's installer disc and do an Erase and Install.

    Issues are usually network related
    What is your internet speed? www.speedtest.net
    6mbps is required for instant HD (you can switch to SD in the settings)
    If on wifi try ethernet and www.istumbler.net to rule out interference

  • Oracle forms 9i - How to return back from a block?

    Some one please help me
    In a trigger, I have a code says go_block. How to return from the block and back to the trigger to continue executing the codes below the go_block statement? Please see example below, I want to come back from block CHECK_STUFF and continue execute the statements
    :Name.option := '1';
    if :name.option = '1' then
    Example:
    Block: Name
    Item: yes_no - Key-next-item trigger
    declare
    begin
    go_block('check_stuff');
    go_item('answer');
    :Name.option := '1';
    if :name.option = '1' then
    Thanks - Patty

    The code behind the GO_BLOCK is executed immediately after the GO_BLOCK, it doesn't stop at that point. So you have to split your code, like
    declare
    begin
    go_block('check_stuff');Then, create a procedure like
    PROCEDURE PR_RETURN_FROM_BLOCK IS
    BEGIN
    go_item('answer');
    :Name.option := '1';
    if :name.option = '1' then
    END;Then, when returning from the block (in whatever trigger you use), just call that procedure.

  • How to convert back from UTF8 to ISO-8859-1 encoding?

    hi,
    I have a bunch of XML files which were wrongly encoded, and we lost all our accent characters.
    ie: é become é
    so how can I recover my XML files using powershell?
    so I want to change all the UTF8 ecoded characters back to the original ISO accent character
    é -> é
    I try this:
    1")
    $utf8 = [System.text.Encoding]::UTF8
    $utfBytes = $utf8.GetBytes("é")
    $isoBytes = [System.text.Encoding]::Convert($utf8, $iso, $utfBytes)
    $iso.GetString($isoBytes)
    but doesnt works.
    so is there a way to do this in powershell?
    I have to scan hundreds of files...
    thanks.

    You can't.  UTF-8 strips all of the information from the characters so you cannot know which characters are which.  If you know which characters you need to fix (requires knowing the spelling of the words) you could possible develop an matrix of
    replacements. There is no simple one line method.
    ¯\_(ツ)_/¯

  • How to revert back from external display mode to laptop display mode?

    Hi, I'm new to this community. I'm not sure if this is where I should be posting my questions. Anyway, I accidentally pressed fn + f2, which switched my laptop into external display mode (I'm pretty sure), and the screen is now very narrow and small. I can't figure out how to switch it back to the laptop display mode. I tried fn + f3, which didn't do anything. I also tried the windows button + p, which wasn't the solution either (I was able to extend my desktop screen, but when I play my Steam games the screen is still very narrow and small). I'm very frustrated because I can't find any answers online. So any information would likely be helpful. Thanks in advance.
    OS: Windows 8

    Hi BorderingOnChaos,
    Fn + F2 is a toggle. You press it again to switch back. If it doesn't work, then something is wrong with your notebook's SCM (system control manager) software or EC (embedded controller) firmware.
    In the future, please do two things:
    1 - Identify your notebook because the answer may vary depending on model.
    2 - This question does not relate to the SteelSeries Engine. The correct place to ask it would be the general "Gaming Notebooks" forum if your MSI notebook is a gaming model. This "SteelSeries Engine" forum is a sub-forum under the "Gaming Notebooks" forum for the purpose of dealing with questions about it---but almost everybody new misses that. The SteelSeries Engine is used to configure keyboard macros and backlighting in MSI gaming notebooks that contain a SteelSeries keyboard as well as accessory devices from SteelSeries like gaming mice and USB headsets.
    Kind regards, David

  • How to roll back from Firefox 29?

    Existing thread has been closed.
    I want to say that I too hate version 29. If I wanted Chrome I'd just use Chrome. The whole reason I use Firefox is that I prefer its interface and operation. At least I used to.
    It's no use you telling me or anyone else that 'it's not like chrome' or that I might just not like the 'appearance'. It is 'like' Chrome and I don't like the appearance. The problem is also the ergonomics - I find it much easier to use tabs at the bottom, MUCH easier to use 'back" and 'fwd' buttons where they used to be, much easier to use square tabs, much better to have a forward button that is always present (even if dimmed) than a tiny thing you have to aim for like an archer, and that is sometimes there and sometimes not. It's much more difficult to find the tiny refresh button located in a place that doesn't suit me - why not have all the commonly used controls over there on the left where they are all in the one place and your poor overworked brain doesn't have to think "Oh yes I'm looking for the 'x' button so I'll look in the place that logically makes sense in the 'x' area" -- which sounds good, but it actually much harder than "I want a control, I'll head up to the top left where the controls are ... ah there it is".
    This new layout is a triumph of overthought and a basic lack of understanding of how 'normal, non-tech' people work.
    The end result is ergonomically poor, no matter what the many studies and much research says.
    And why the need to change in the first place? Many of us use FF because it was what it was, and we liked it. What's with the need to change for no reason? If it works, stick with it.
    The whole thing looks like a poorly thought out response to 'we need to update because other browsers look cooler/sexier/more curvy/something than ours, so let's update'.
    Someone at Mozilla needs to appreciate that change is irritating in itself, requires substantial input from the user, and therefore should ONLY be used when there is a compelling reason. Which there isn't.
    Gah :(

    I would not recommend downgrading Firefox. Unsupported versions are not secure. You increase risks to your System and Personal data by using insecure software. When security fixes are released and publicised that also publicises the potential exploits.
    * [[Install an older version of Firefox]]
    * https://www.mozilla.org/security/known-vulnerabilities/firefox.html
    Try the new design, if it does not grow on you there are ways to make it more like the previous version.
    * See [[Learn more about the design of the new Firefox]] <br /> [[Common questions after updating to the new Firefox]]
    * [[How to make the new Firefox look like the old Firefox]] <br /> https://addons.mozilla.org/firefox/addon/classicthemerestorer/
    '''One of the developers recently posted this explanation'''
    [https://support.mozilla.org/en-US/user/1079955 MikeDeboer] said
    Each setting you see in a computer program you use requires work; when a developer wants to build something new or improve something, he or she has to go through each related (hidden) setting and test if it still works like before and do that on each platform Firefox runs on. That's Apple's Mac OSX, various flavours of Linux and various flavours of Windows, including Windows XP. This costs time, lots of it, and that amount grows exponentially with each setting that's added. This comes on top of our work to continuously fix, improve and innovate Firefox. <br /> <br /> That's why we also removed the tabs.onTop preference. Awesome community members, who were unhappy about that change, created the Classic Theme Restorer add-on. They deserve our collective hugs.

    Are you having any particular problem ? We may be able to suggest a workaround.
    '''Have your say. Note Firefox 29 is to some extent work in progress.'''
    People helping here are mainly volunteers and users of Firefox like you and I. If you feel strongly about the new changes I would suggest you make a short comment and provide feedback on https://input.mozilla.org/feedback for the people who decided on the changes to actually see it.
    Personally one of my major gripes is that the upgrade happens without prior warning of major changes, and then we are left in a changed Firefox trying to find out what works still. <br /> Sure the new features can best be demonstrated from the new version, but some prior warning with a chance to read up about the changes would surely help.

  • How to get back from a hyperlink?

    The hyperlinks that can be inserted in iBooks Author work great in the direction out, at least from what I can tell in preview: There is a 'folding-over' animation that gets you from the book page to the website. But I find the reverse awkward: All I could do was hit the home button to get to the app screen and then hit iBooks again, which gets me back to the page I left. Is there a more elegant, i.e. one-step,  way of doing this? It may be that this is a standard procedure (switching back to the preceding app) for people who are used to apps on the iPad--I am new to it. I have just completed my first ebook with iBooks Author...

    This is the answer I received in a different thread from D. Bourne:
    Four fingers from right to left gets you back to the iBook. I would think it could get confusing with more apps but just gping between the two should be useful. Getting back to links within the book is not as easy (??).

  • How to downgrade back from IOS 4.2.1

    I have had enough of woes with my I-Phone 3G, after upgrading to IOS 4.2.1.
    Any way of backtracking to a more stable state? I was fine till IOS 4.1. though the performance was slowing down. Now totally stuck since last 3 days.

    Ok, let me tell you what I tried to do. Restore through Itunes didnt work, got a lot of errors mainly pointing to hardware issues. I once managed to get it jailbroken through a friend, and then asked him to reset it completely so I could restore it in Itunes again (I had no compulsive intention to remain jailbroken then, I wish I had not reset it and continued using it in jailbroken mode).So I have just one choice left now...jailbreak. I am just looking for a reply from Apple before I go ahead with jailbreak.Wonder how long my patience will last, 3 days and 4th starting.

  • APO/BW: How to get back from APO to BW/ How the send data from BW to APO

    Hi,
    1. I read that BW is the “data layer” for APO DP and therefore, I expected data to flow from BW, the data layer, to APO DP but not the reverse. Yet, I also read that “data can be transferred from ‘Livecache’ back to BW by using the ‘extractor technology’ from BW. Can you clarify this for me?
    2. If possible, please provide the steps to use this extractor technology to extract data back to BW in detail so that I can try it.
    Thanks

    Hi Amanda,
    1. The data flow is from BW to APO, and from APO to BW.
    from bw to apo, to feed planning area, characteristic value combination, in APO we have infocube to feed the data, as we know APO has BW inside (all the tcodes RSA1 etc are valid), datamart scenario is used here, we create infocube in APO, update rules, infosource and assign datasource from BW.
    The data flow from APO to BW, to get the plan data inputted by user, we generate datasource in APO from planning area (compare with 'generate export datasource' from infocube), transaction /SAPAPO/SDP_EXTR. 'extractor technology' here in practice is just like when we are using datasource
    take a look
    http://help.sap.com/saphelp_scm50/helpdata/en/c9/199170f13711d4b2f20050da385632/frameset.htm
    2. as mentioned in #1, you can use the transaction /SAPAPO//SAPAPO/SDP_EXTR to handle planning area-datasources in APO, or /SAPAPO/MSDP_ADMIN - planning area; choose your planning area, and menu extractor tools (or generate datasources), again datamart scenario is used here, after the datasource generated in APO, it's replicated in BW (APO act as source system), the rest steps are just same as when extract data from other SAP source system
    simply what you need to practice is /SAPAPO/SDP_EXTR to 'generate export datasource', the rest steps should be familiar already for you
