Uninstalling OS X Server Snow Leopard

Hi. I set up Snow Leopard server on one Mac on our net to test it out before I installed it on another.
Is there a way to uninstall it on the first machine so I don't get the "Invalid Serial Number" error message on the desired server?
TIA,
- Alex Zavatone

Is there a way to uninstall it on the first machine
You mean other than running a clean install of Mac OS X?

  • Upgrade mysql in Mac Os Server Snow Leopard 10.6.8

    Hi
    The built in mysql server on Mac Os Server Snow Leopard 10.6.8 that I have bought is 5.0, I need to upgrade it to 5.5, how do I do that?
    I followed these instructions
    http://support.apple.com/kb/HT4006
    Everything went smoothly except that the server is not upgraded still the same version.
    Thanks

    Chris is right. The only way, you can upgrade to 5.5 is by doing it manually. Apple will probably update to a later version with Lion. But MySQL version updates have been rare in the past.
    Installing a different version is pretty straightforward, but you can not use SA anymore and have to configure the php, apache in the correct way. There are plenty of links out there which can help you.
    So long.

  • WebObjects and Apache2.2 on Mac OS X Server (Snow Leopard)

    I have been configuring a new Mac Mini Server with the latest version of Mac OS X Server.
    Typically we have been using Max OS X (non-server) in development environment and were following our instructions on how we set up all our boxes.  In setting up our new installation on the "server edition" we came across something that caused up some pause.
    After we got our WebObjects application launched through JavaMonitor, it attempted to open Safari, but "page" could not be found.  We suspected that that WebObjects Adaptor was not being utilized.
    Looking through the Apache logs we found this:
    script not found or unable to stat: /Library/WebServer/CGI-Executables/WebObjects
    We checked our httpd.conf (Apache 2.2.17).  This file is slightly different that the one for our generic (non-server) Mac OS X Snow Leopard installations.  It even mentions that in the comments at the top of httpd.conf file that ships with Mac OS X Server
    We had included the following as we normally do -
    Include /System/Library/WebObjects/Adaptors/Apache2.2/apache.conf
    But in order to get WebObjects to kick in, we needed to comment out the line
    #          ScriptAlias /cgi-bin/ /Library/WebServer/CGI-Executables/
    Once we did that... boom... app was working fine.  Since all that is running on this box is WebObjects and Oracle, we are happy with this solution. Moral of the post is that the httpd.conf file supplied is different between "Mac OS X" and "Mac OS X Server" editions. 
    Note:  We do not even see the ScriptAlias line in our non-server httpd.conf.
    We were clued into this from a previous discussion on here (and its related replies). http://discussions.apple.com/message/12786408#12786408
    Hope this helps someone else.

    If you have another administrative username (such as the Open Directory (OD) Administrator (diradmin) username, then you can use that to reset the password. 
    If you don't have another administrative password including a local administrator and if it's your Open Directory Administrator password that you've forgotten, then you'll want to follow HT1194 Mac OS X Server: How to reset the Open Directory administrator password for the sequence used to reset the OD access.  (The header of that article lists up through 10.5, but the text also lists 10.6.)
    Once you're back in, you'll probably want to consider adding a back-up directory administrator account with an obscure password, and write down that password and stick it in a fireproof safe somewhere, or maybe in a note in your Keychain of your own OS X client system, or some other secure location.  I do that with a few servers, storing that data with full-disk copies of the server backups, etc.

  • Where can I Purchase OS X 10.6 Server Snow Leopard?

    I recently purchased a Mac Mini with OS X Mavericks installed.  I have several database & spreadsheet documents created under Appleworks 6 that I have used for years and want to continue to use but Appleworks will not run in Mavericks.  I have installed Parallels Desktop 9 for Mac and wanted to create a Virtual Machine to run OS X 10.6 Snow Leopard.  I tried to install Snow Leopard from my installation DVD and Parallels indicated I must have the OS X 10.6 Server to create the Virtual Machine.  I looked in the Apple Store and did not find such a server for sale.  Where can I obtain OS X 10.6 Snow Leopard Server?

  • Help with CF9 Standard Install and Mac OS Server (Snow Leopard Server)

    Hello,
    I recently purchased a mac mini server (with snow leopard server) and will be using it to host my CF9 applications.  This install is WAY different than the install needed on a windows machine.  I tried to install it once and somehow hosed up Apache and now I can't even get it to start up (apache).  So I am having the colo company to do a full restore of the server and I took notes on the Mac Server install and below is the questions I have.
    1.) Since Snow Leopard Server comes with Apache webserver, it is what CF wants to use.  This is fine, I just need to know where these things are...
    It is asking for the Configuration Directory:  I'm guessing it is /private/etc/apache2 ? Right or Wrong???
    2.) It is asking for Directory and file name of server binary:  It currently defaults to /usr/sbin/httpd  is this right or should I point it to another directory?
    3.) It is asking for Directory and file name of server script: It currently defaults to /usr/sbin/apachectl  is this right or should I point it to another directory?
    It also wants the location where I can place the CFIDE.  Can I place this anywhere I wish or is there a preferred location to point this to?
    and finally, I have CF9 Standard, so on the mac server should I install it as a server configuration (self contained instance) or Enterprise Multiserver config.  I was reading online that its better to install as an Enterprise Multiserver setup, but I don't know if this will work for me since I'm useing the standard edition.
    Please Help ANYONE, if you have mac os experience and installing CF9 onto a mac server
    Thanks

    I have been getting this exact same problem.  CF installer is somehow writing some invalid information into the httpd.conf file.  I was able to replace the httpd.conf file with the default one, and was able to go through the webconnector process again and (sometimes randomly) it works.  I also spent about 4 hours on the line with adobe CF support and made no progress beyond what I'll post here .
    To answer your questions about file locations:
    /private/etc/apache2/ for the httpd.conf files
    /usr/sbin/ for both the apachectl and the httpd binaries
    Although I'm able to get past where you are, and it seems to work correctly, Immediately upon adding a new site via server admin it all breaks.  Coldfusion then will only work if I manually go to a cfm document.  For example:  http://example.com/ will give me the raw text from the (default index) index.cfm file.  But typing http://example.com/index.cfm works.
    I am lost here as well.  After 4 hours on the phone with adobe support I would have hoped it would be an easy fix.  I've completely nuked and reinstalled the server from scratch with the exact same results both times.
    Does anyone have the slightest clue about what may be going on here?

  • Tiger server, Snow Leopard Client and Illustrator CS4

    We have a strange problem happening with the one Snow Leopard client we have accessing our Tiger server. In certain directories (not in all) if the user opens an Illustrator CS4 file, makes changes and goes to save the file they get the message that the file is either locked or in use by another user (it is not). This does not happen with any other kind of file in that same directory. The server is connect to AD so the user accounts come from the AD but on this machine we have the same problem regardless of the user account used to mount the server volume. It also doesn't matter if I use a local account on the server to mount instead of AD. I have the same problem if I connect via SMB instead of AFP. Other machines (Leopard) can work on these files with no problems.
    A couple of other bits of information which might be useful. If the user opens the file, does a save as to the same name and same folder and replaces the original they can work on the file and save it with no problems. As soon as they close the file and reopen it they have the problem again. Also, if they run into the problem, close all programs on the computer and try to unmount the server volume they get the message that the volume is in use and cannot be ejected. I have checked and there are no invisible files being created in the directory where this file resides.
    What is strange is that the problem does not happen in all directories although when it happens it is repeatable in that directory. Happens every time. I have tried changing the name of the folder to something simple and it still happens.
    Any suggestions on where to go with this problem??

    No progress yet. Have tried a lot of things with preferences on the server. I have confirmed with another snow leopard machine that this is not related to the machine in any way. I have not yet had a chance to test it on another Tiger server but given the fact that you are seeing it as well I would say there is a problem with the two operating systems cooperating.
    As I said, I do have a temporary workaround. If you do a save as with the document, choose to overrite the original it works and then lets you continue to work on that file and save for that session. After you close the file and reopen the problem returns but at least for that session you are fine.

  • Mini Mac 10.4.11 to Mini Mac Server Snow Leopard

    Im interesting in getting a 2010 mini mac with server.
    BUT I have a mini mac 10.4.11 with photoshop, lightroom,etc. (Actions,history, etc)
    I know that I can't transfer from 10.4.11 to Snow Leopard, Do I HAVE TO upgrade the Snow Leopard onto my OLD Mini Mac 10.4.11 and then get Firewire Cable to trasfer my Applications such as Photoshop and Lightroom over no problem?
    It would be a pain in the a** to do all over again with those install adobe,etc!
    Hope theres something to make my life abit easy!
    Cheers!

    No, you do not have to upgrade the older Mac mini to Snow Leopard in order to migrate your stuff to the new mini. However, Adobe products are some of the hardest to migrate because they have files spread all over the place and sometimes they do not all get migrated. Many folks find that everything works better with a fresh install on the new computer with 3rd party applications, like Adobe.
    Your older Mac mini may have FireWire 400 and the new Mac mini has FW800, so you will need the proper cable, FW400 to FW800 to connect the two minis with FW. But you can also migrate over a wireless connection or an Ethernet connect as well. The latter two are just slower than FW.

  • How to upgrade Mac mini server Snow Leopard to Mountain Lion

    Trying to upgrade Mac mini server running Snow Leopard to Mountain Lion. I downloaded Mountain Lion and about to install but a warning prompt tells me server functionality will be lost until server.app is applied. What is involved in doing that?

    What's involved?  Buy and load OS X Server; that's now a Mac App Store app.
    That'll get you Server.app.
    Server.app is the GUI tool that is used to manage recent versions of OS X Server, along with (increasingly) the command line management of the features that are not exposed through the Server.app tool.

  • HP 2101nw Wireless G Print Server & Snow Leopard (OS X 10.6)

    Hi everyone,
    Before I start, I must point out that I have a Win 7 laptop connected to the HP Photosmart C5280 with the HP 2101nw Wireless G Print Server perfectly.
    Appears that Snow Leopard is not compatible with ths device. The Hp Connection Manager 'sees' the printer, but I am not able to connect to it.
    The drivers on the CD and online mention that it will work woth 10.4 and 10.5, but no mention of 10.6 (I am on 10.6.5). However, installing it from the .dmg file on the drivers page, I get The system extension "/System/Library/Extensions/HPVUSBFamily.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update.
    Just wondering if anyone from HP can confirm this is a driver being worked on, or is this device 'obsolete'?
    Regards,
    Stephen

    Same problem here. New imac with Snow Leopard (10.6.6). Previously working with 10.5 on MacBook Pro.
    As for 'Shogan' above - The Hp Connection Manager 'sees' the printer, but I am not able to connect to it.
    I reinstalled software/drivers from the .dmg file on the HP support page, I get The system extension "/System/Library/Extensions/HPVUSBFamily.kext" was installed improperly and cannot be used.
    I can select the printer from the Connection manager list but the printer remains 'offline' and the 'Status: Idle'
    Come on customer support.....give these customers some....well, support.

  • How to uninstall Lion and restore Snow Leopard?

    I did upgrade from Leopard to Lion 10.7.1 two days ago. After that my 2.8 GHz Core i5 4GB DDR3 start to jerking, I sometime even start any applications. That is never happen before when running on Leopard. I can not work for two days already. Anybody can teach me how to restore my iMac to Leopard without harming data stored?

    Kappy has a nice writeup, but basically.... back up your data, boot from your Snow Leopard DVD (hold C), go into Disk Utilities and erase your Lion partition. After that completes, back out of Disk Utilites and install Snow Leopard, reinstall your apps and restore your data.

  • Anyone know how to uninstall Lion and reinstall snow leopard without having to pay the $29?

    Ever since I purchased and downloaded Lion I have been having problems (applications not running properly or not at all and the computer locks up like every 10 minutes resulting in me having to restart) and want to go back to snow leopard until I feel comfortable that Lion is ready to go.

    Thanks Roscoe . . . .
    I came back to this forum to share my experience. I'm working with a 2007/08 - 17" MB Pro. With the LEOPARD OS, not Snow Leopard. I used my original discs and reformatted, reinstalled Leopard. I was able to open Time Machine and restore the files saved on on an external drive. I used this time to make changes to my Apps, and having just doubled my RAM prior to the 'Lion Upgrade', had no issues of slowing or freezing as others are apparently having. Like you, this was relatively painless, though it did take some time to transfer all of my files.
    I hesitated performing this process for nearly a month, but kept checking my back-ups to ensure that I had still some saved from the Leopard days. Unfortunately, I was unable to do much of anything. I'm a graphic designer and sell items online, EVERYTHING came to a complete stop with Lion. I couldn't communicate with my printer at all, no fax, no copies, no prints, no scans. I couldn't download images from my camera. Some of my Apps, stopped working, I hated the missing 'Save As' feature. My image viewer and browsers crashed constantly, and my home network 'LOST' me! I couldn't take another day of NO productivity!
    My advice to anyone changing or upgrading ANY O.S., whether Mac or PC, always; ALWAYS back up your drive first! We should be backing up often anyway, but it is certainly important to ensure the security of all of your files and program downloads or installations by copying everything prior to making any hardware or software changes. For a small investment of $50 to $100, you can get an external drive. Having the capability of restoring all of your data is  . . . priceless!
    Thanks everyone for sharing. Good luck to those experiences these problems. Have Faith, Apple will fix it's issues, and the other manufacturers WILL catch up on the driver codes. We all just need to be patient, until then;  keep on 'backing up'!
    *** JJ; were you able to restore an earlier back up? Did that fix your issue? I found a great deal on RAM from Crucial, sometimes this will help increase our speed and performance . . . . just a thought.

  • Ical Server Snow Leopard email notification: just a clarification question.

    Hi,
    I succesfully installed my mac mini snow leo server.
    Our scenario: icalserver calendar is used by 4 clients in our network.
    ical server is running fine, but there is one thing I
    do not understand: the workflow of email notification.
    On the server I enabled email notification and set up an email adress [email protected] in Server Admin / Emailnotification.
    Then I created a test event in ical. I did not use the local calendar,
    I used the caldav calendar.
    Then I was wondering: why did mail start on mini server to send the invitation ?
    Email data is still stored in Server Admin / Email notification, so I assume email is sent independently in the backgound from any mail programm !??!
    It would be nice if anybody could give me any advice.
    Thanks

    Invitations are sent to external email recipients directly by the server posting them to a known mail queue, (probably in your case on the same mini). There is a calendar server manual online which explains, and calendarserver.org where the project is based. I was only able to make it work using the internal account names, not a friendly one I set up for the purpose.
