Will Leopard work instead of snow leopard on my 2010 mac pro 12 core?

I am having issues in finalcut 7 shuting down using snow leopard. I bought a new macpro 12core last january and started having this problem. all upgrades were done, no change. had a copy of leopard(10.5) and tried a clean install. computer will not recognize disk. tried tiger, same deal. my main question is will it work on the mid-year macpro's?

Any Grey Discs would be machine specific.
It is sometimes possible to install an earlier OS, but...
Don't install a version of Mac OS X earlier than what came with your Mac...

IWork '05 will not work since installing Snow Leopard

I have iWork '05 and use Pages and Keynote. Since I installed the Snow Leopard update, when I open Pages all I get is the side toolbar and nothing else. I went to preferences and choose "open blank template" and then it says that it is "unable to open", and I tried using a template that I have created previously and that would not open either. When I choose "Open on Template Chooser" then nothing happens.
I can't get any files to open or new documents.
I am unable to install updates for iWork because I am running '05 and not '09.
Please help.

iwork05 is not compatible with snow leopard. you need to get a newer version. iwork08 is available on amazon for 20$ used and 30$ new.

Will the newest version of Safari Mavericks work properly with Snow Leopard?

Will the newest version of Safari Mavericks work properly with Snow Leopard?

Are you asking if you can install Mavericks on a machine running Snow Leopard?
Upgrade to Mountain Lion/Mavericks.
Check that your computer is compatible with Mountain Lion/Mavericks.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
iMac (Mid 2007 or newer) model number 7,1 or higher
MacBook (Late 2008 Aluminum, or Early 2009 or newer) model number 5,1 or higher
MacBook Pro (Mid/Late 2007 or newer) model number 3,1 or higher
MacBook Air (Late 2008 or newer) model number 2,1 or higher
Mac mini (Early 2009 or newer) model number 3,1 or higher
Mac Pro (Early 2008 or newer) model number 3,1 or higher
Xserve (Early 2009) model number 3,1 or higher
Your Mac needs:
OS X v10.6.8 or OS X Lion already installed
2 GB or more of memory (More is better - 4 GB minimum seems to be the consensus)
8 GB or more of available space
Check to make sure your applications are compatible. PowerPC applications are no longer supported.
Application Compatibility
You can also check which applications are PowerPC by going to the  menu, select About this Mac, click on More info…, then click System Report and select Software/Applications.
If you do decide to upgrade, make sure you do a backup before installing.

HT201250 My 10.7.3 Time Machine won't work with external disks. Worked fine with Snow Leopard, and even Lion 10.7.1

My 10.7.3 Time Machine won't work with external disks. Worked fine with Snow Leopard, and even Lion 10.7.1
I have tried everything, even buy new external disk from different manufacture.
If I cant get a fix soon, I am downgrading back to SnowL.

Still no luck. I tried all the tricks, reconfiguring TM (remove selected disk option, and re-setting it, and trying different disks). Tried new combo updater, and the newer TM update after that. Tired two different disks too (one is my older firewire WD MyBook 1TB, and my brand new 3tb Seagate GoFlex USB... either one plugged into back of computer - no intermediary devices). I did get the TM buddy wiget and it produced the following log, from the last attempt, where I setup lots of exclusions so that backup quantity was small (under 10gb). Still it failed to complete. Here is that log, for what it is worth:
Starting standard backup
Backing up to: /Volumes/TM-Disk/Backups.backupdb
9.56 GB required (including padding), 911.15 GB available
Waiting for index to be ready (101)
Copied 0 files (0 bytes) from volume Mac HD.
Backup canceled.
To prove a point, I will take these disks are run them on my other Tiger and Snow Leopard laptops to prove TM works fine on those with these disks. But I fear the only options are to either have my tech re-install LION... or just have him reinstall SL instead. Im at wits end.

Please help Apple??? It worked fine with Snow Leopard??

I recently upgraded to Lion and now cant see my Windows 7 laptop in network? Or see my macbook Air 2010 on my win7 laptop. Please help Apple??? It worked fine with Snow Leopard??

You're not addressing Apple here, you are addressing a user based community. An Apple employee may read your post but he/she will not officially respond to it.
You didn't say if your networking is Wi-Fi or USB Dongle based so I'm assuming Wi-Fi in this response. If you do a search of the forums you will find that quite a few are having Wi-Fi issues with Lion--things that worked fine with Snow Leopard are flakey or don't work at all with Lion so your problem may be another instance of the Wi-Fi issues in Lion. If not, then perhaps someone with knowledge of your specific issue will post. I see my other Macs (MBP, 24" iMac, 27" iMac all running Lion) fine but I don't have a PC to test.

Home computer is Lion, Work computer is Snow Leopard

My home computer is Lion, my work computer is Snow Leopard. My work computer needs to stay Snow Leopard becuase of a major program which runs the presspress department is not supported with Lion yet - so I cannot upgrade yet. I also jsut got an iPhone and want to use iCloud so that all three of those two computers and my iPhone sync together.
So, if I use iCloud for my home and my iPhone, what does that do to my work computer running Snow Leopard? Can I still get my mail just like I always do through "Mail" at work? I guess I just need to know what will change for my work (Snow Leopard) iMac?

You do not lose your mail account when MobileMe terminates in June. However, when you move to iCloud you will not be able to sync your calendar or contacts with the Snow Leopard computer. You may want to read the following:

I have a MacBook White. Everything worked great with Snow Leopard including Mathematica, and all Pogo games. I downloaded Lion two days ago and now neither program works. The box states that I need J/Link, and/or java runtime. Help.

I have a MacBook White, early 2009 model, just downloaded/installed OS X Lion. Everything worked well with Snow Leopard - Mathematica, pogo.com games. Now, with Lion, I am getting a box that states I need J/Link, and/or java runtime. Software update feature states all software is up to date. Help.

What about the incredable lag time from clicking on a program to the time it opens (or the time till the loading screen starts)? I wish I could record it and play it so I could see if thats normal from other members... the icon just sitting there for over 35 second (I just counted 36 till the loading screen popped up) at first I thought it was me not clicking hard enought cuz the mouse button I have is real stiff (any ideas on that?) but no it takes that long just to get to the app loading screen... this happens every time same amount of time with the 3 programs I use the most, prolly more but I know for a fact world of warcraft, uTorrent, and Google Chrome. I would just chalk it up to slow hardware but they load real quick in windows 7 and once this bad spot is loaded the program runs so fast and nice afterword. Maybe some tweeks? I wonder if this would happen in Snow?
The coment "few outdated programs" Ive seen alot its not just a few its a lot and since games are not Apple's strong point I would think they would want to keep as many as they could...
An example of the rants you will see from a lot here. Don't be put off as these problems are generally user specific, and these same old comments come out after the release of every OSX I can remember. When Lion is upgraded to the next OSX you can gaurentee these forums will be full of people screaming about how great Lion was. Happened with Tiger, Leopard and Snow Leopard.
So come to think of it you may be better off Googling sites that give you unbiased views on Lion, rather than expect any positive comments here. For every one complaint there are probably 100,000 people with no issues.
Cheers

I took Lion off my Macbook Pro and put Snow Leopard back on and now I can't access Mail or iPhoto. How do I get Mail and iPhoto to work with the Snow Leopard I just put back on?

Hi. I was having slowness problems with my Macbook Pro and thought I would re-install Lion but put Snow Leopard back on by mistake. I bought the computer used with Lion on it and don't have access to the USB drive or a username/password to reinstall Lion. Now I can't access Mail or iPhoto since I put Snow Leopard on.
Is there a way to get my Mail and iPhoto working again with Snow Leopard or do I have to "re-upgrade" to Lion?
Thanks!
Steve

You can't. When you converted those libraries to Lion's format, you lost the ability to go backwards. Unless you saved a bootable backup./clone or Time Machine backup of your previous SL installation, you're up the proverbial creek w/o a paddle.

My app will no longer run under Snow Leopard, runs fine under Lion.

My app will no longer run under Snow Leopard, even though it was originally written for Snow Leopard. It runs fine on my Dev machine under Lion. But when I test it on my Snow Leopard Mac Mini the app starts but the window does not appear. Going to file, new window does nothing. My depolyment target is set to 10.6. Is there something I did to make my app lose Snow Leopard compatiblty?

Does your application use features only available in Lion? Are you getting any console logs?

Font not working after loading snow leopard.

My font named Smash is not working after loading snow leopard. Is there any way to fix this?

I suspect you're talking about a free font called Smash. Read Kurt Lang's paper on font management
<http://www.jklstudios.com/misc/osxfonts.html>
and especially his strictures on free Windows fonts. The free Smash is a good example of what his talking about. It's a bad, poorly made font. Trash it ASAP.
If you want to check it with Font Book, use File > Validate File…, then locate smash.ttf and proceed. You cannot use File > Valide Font, because that command works only with installed, 'working' fonts.
For the real font, go to

FF 3.15 worked perfect with Snow Leopard. But everything after that, till FF 8, crashes left and right. On Facebook. And on ALL different language websites. Should I stop using FF? Heard Chrome is good.

[Edit: It should be FF 3.5. I mistyped FF 3.15]
I have MAC OSX Snow Leopard. 10.6.8.
FF 3.5 [apologies; I mistyped 3.15] worked perfect with Snow Leopard. NO problems.
But '''everything''' after that, till FF 8, crashes left and right.
Facebook crashes the most within few short seconds.
And NO different language websites even open.
I read online to use Safe Mode and try. I did. No change.
I read online to reset font cache or or something using atsUtil from the Terminal. I did. Nothing.
It is super frustrating. Same problem in my wife's Mac as well.
Should I stop using FF? I heard Chrome is good.

Will The Genius Bar Install Snow Leopard in 2014?

I have an intel-based MacBook Pro from 2009 (I think) that is running 10.5 and I'd like to upgrade to Mavericks.
If I make a genius bar appointment, will the tech there install Snow Leopard for me (I'd pay for Snow Leopard) as opposed to me ordering a disk from Apple?
Thanks,
K

Call them and ask, although they may not have the retail media available (and otherwise would only install it for you if part of a hardware repair and if that was the original OS for your machine). Either way, they will charge you for the media, and if they do it, they will likely charge for time as well.
The disc is only $20 - http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard and its not hard to upgrade yourself. Just make sure, as always, to make a full backup before attempting any system changes.

Why doesn't LightScribe work with my Snow Leopard?

Why doesn't LightScribe work with my Snow Leopard? It downloaded and is in my printer folder, but won't open.

Are you really still running 10.6.3? If you are you should run the combo update as many issues were resolved within the updates themselves.

Re installed leopard instead of snow leopard!

Help! I needed to change my mac book password and re-installed the OLD OSX dvd instead of snow leopard what can i do as I have no view of all my files etc...!!

Ally4749,
when you’d reïnstalled Leopard rather than changing your password, did you wipe clean your internal disk in that process? Try opening a Terminal window, then run the following command there:
ls -l /Users
Please include in your reply the full output from that command.
