Can I use Unix symbolic links between Mountain Lion and Snow Leopard Mail folders?

After upgrading to Mountain Lion, I partitioned my iMac HD to have two partitions: Macintosh HD has Mountain Lion; I reinstalled Snow Leopard on Macintosh HD 2. Best part: you can access your user-created files from EITHER disk partition. But not so OS X Mail. I wanted to revert to Snow Leopard, since I don't like the iOS-like Mountain Lion (swipe THIS!), but Mail is a problem since all my Snow Leopard Mail was successfully migrated over to Mountain Lion during upgrade.
Is there a way to use Unix symbolic links between actual OS X Mail folders in Mountain Lion and OS X Mail in Snow Leopard?
It seems the (trial) symbolic link created pointed to a blank file.

It's not a matter of "letting" each maintain its own database, William. By default, I believe, I have no control over what gets written. In fact, if there were a way to set a preference that says, use this index named "spotlightindexSL' only [while in SL], that might solve my problem. Then when booting up in ML, it would just go after the index it last made.
My guess is that while I am in ML or SL and not the other, there are all sorts of changes to files and the system freaks and says "Oh, now look at what a mess I've made — there are all sorts of files unaccounted for. Now I have to rebuild the whole thing."
I have 2 had drives in my Mac, both 500GB. One (Working Disk) has no operating system and all my files, and the other drive is partitioned 470/30gb with SL on the 470 and ML in the 30. When I restart in either OS, the auto-start Indexing as if for the very first time, and do both hard drives (in total: 3 partitions of files, not counting the ML Restore partition).
I know it all uncoventionally — just wanted to see what my $20 new OS will cost me in software upgrades, in particular my $1800 Adobe Design Suite CS4 and a few others.

Home Sharing between Mountain Lion and Snow Leopard

Hi
I have MacBook Pro both at work and at home. The one at work has Mountain Lion with the latest version of iTune and the one at home has Snow Leopard with iTune 10.7.
I want to share movies on my iTune account between Mountain Lion and Snow Leopard. However, it doesn't seem to work....
How can I solve this problem?
FYI - I am not a big fan of Mountain Lion and do NOT want to upgrade my home computer to Mountain Lion.

    I am not sure why you can't access iCloud, using a browser? Then you have the same address book, so long as you are connected to the internet. https://www.icloud.com/
    No email involved. From the browser, you can download individual iCards or all of the individual cards, BUT unfortunately, not the Groups. So, you have to fiddle on the SL machine with keeping the groups organized.
    Up until recently, I have been able to sync Contacts from ML (which stays synced to iCloud) to SL this way: copy the /Users/~/Library/Application Support/AddressBook/ folder from the ML computer to the SL computer by dragging the icon onto the dock's AddressBook icon, this should retain all the group info. But, recently, this has ceased being complete.
    Apple really left us behind on this one.

Syncing contacts between Mountain Lion and Snow Leopard?

One of my computers is running Mountain Lion, and the other is running Snow Leopard and so does not have access to iCloud. Is there any way to sync Contacts between the two computers?

Sharing users between Mountain Lion and Snow Leopard -- will this break preferences?

I have now ML and SL in dual boot and want to share users (on an external drive), and try out the new XCode. I wonder, however, if I should rather use different users, so XC on SL won't have to deal with "corrupted" preferences that new XC might write to my users folder. Also I thought it would be a good idea to switch off Spotlight and TimeMachine in ML for external harddrives, so they will still be readable from SL. Anyone has some tips on how to use SL and ML with shared external drives?

You can upgrade the iMac for no extra charge - sign into the App Store there, download and install 10.8.
I recommend that you make a backup (Time Machine is probably the easiest method) before you install, and make sure that you are not using any applications that are incomptible with 10.8 (eg Office 2004) - other than that, it should go smoothly.

Dual boot drive - Mountain Lion and Snow Leopard - Correct order to load software /apps?

Hi
I want to create a dual boot drive for Mountain Lion and Snow Leopard as some of my hardware (is not supported in Mountain Lion).
I am happy how to do this, I just want to know if there is a correct way to install software and apps.
My plan was to do a clean install of both using two partitions, the larger going to ML and smaller one for SL. I was going to install SL from the DVD and then after updating from 10.6. to 10.6.8 and download ML from the app store and install on the larger partition.
Do I install all the software I use like Final Cut, Aperture, iLife (for Garageband) etc on the ML or SL partition or on both. Also, is there a better way / practise of the order software updates / apps and boxed software should be installed when doing a clean machine install.
Thanks in advance.
Matt

Thanks mende1
So, if I have software I need to use on both ML and SL - for example Final Cut as I have a Canopus AVDC box which is not supported in ML but only SL, do I need to install the same software in both OS?
I usually open apps using spotlight and didn't know if it would software / apps would open if already installed on the other partition?
Thanks again
Matt

Can't find photos after downgrading from Mountain Lion to Snow Leopard

I downgraded from Lion to Snow Leopard as my comuter was really slow (probably right at the min requirements for the new OS)
I can't locate my photos from my Time Machine. How do I access these? I have reinstalled everything back to Lion to try to get them off my Time Machine as it currently won't let me go back in time past the date when I down graded to Snow Leopard..
I am a dead man if I don't find the photos of our kids....

A good ressource for Time Machine questions is Pondini's Time Machine - Troubleshooting
Have a look at the section Time Machine - Troubleshooting E2. I can't see some backups
as it currently won't let me go back in time past the date when I down graded to Snow Leopard..
You probably now have two different Time Machine backups - after the downgrade TM started a new one. Have you inspected your backup disk in the Finder and looked what backups are there?
You should see a folder "Backups.backup.db" and inside the current backups for the computers you are syncing. Is there more than one? Open the folders and look at the dates. Is there any backup from last year?

Using one program Application on both Lion and Snow Leopard

I have to constantly reboot/restart between Lion on my New Thunderbolt Mini and Snow Leopard off and External Drive. What is the recommendation for using programs (which are built to run on both) such as iwork pages. Should I use one program off the Main Lion Internal HD? or as I have now - Maintian two programs, one on each hard drive. I can see Lion is having difficulty as it can see the other program and sometimes it launches the version on the SL drive. When in Snow Leopard the OS cannot search and therefore not register items not included in the Main Boot Drive.
I am a single user, so I'd like consistency in maintaining templates (and now version!?!) when I want to draft a letter and can't waste time to reboot. All my documents on both OS's are directed to a 3rd Drive to effectively keep my sanity. I was syning the preferences previously for mail and passwords,etc but recently the functions of Lion have expanded so much beyond SL as that I had to swtich off this sync to avoid conflicts.
Should I keep using two programs or when available use a single version. Noting this wont be on the boot drive of one of them. If I go to one. Can I keep the other on its boot drive in case of transporting it to another machine. Is there a way to park it so it's not referenced to use when I launch by opening a file? I though about zipping it? What happens when a version update might excel beyond SL? The current programs known already have 2 versions residing on each boot drive. If I go to 1 and a software update comes along, that would be a problem.
Any and all experinces and suggestions are appreciated.

Why? There is no good way to do what you're doing.

Can Mountain Lion and Snow Leopard share Spotlight indexes?

I have a Starup Volume with a new partition I added to install Mountain Lion on to get a feel for what Apps I will lose if/when I switch over from Snow Leopard.,
I did this yesterday and it's working fine. I can star up most of my Snow Leopard Apps, but I have to go to the Apps folder on the SL partition to do so. That's not a huge issue to me.
However, I notice that when I switch back/forth between OSX versions, Spotlight re-indexes the volumes, so it appears the invisble index file stored at the root level of the volume is not corss-compatible... or is it?
Does anyone know of a way to get both systems to read off the Spotlight Index either creates?

Lion and Mountain Lion and Snow Leopard, oh my!

My iMac does not support OS X Mountain Lion, but it does support Lion; is there anyway to upgrade to Lion? In the app store I can't find a way to download Lion now that Mountain Lion is available. Currently running Snow Leopard. Want Lion so that I can back everything up on iCloud.

How do I switch from Mountain Lion to Snow Leopard? New used computer that I don't have anything on yet but has Mountain Lion installed.

I just puchased a used 2008 MacPro 2.8 ghz 8 core and it has Mountain Lion installed on it. I want to go back to Snow Leopard because it is a better stable OS for using Final Cut Pro 7. I just bought the Snow Leopard Discs to install. I need to erase the hard drive and install Snow Leopard. Any help on how
to do this? Thank you.

Downgrade Lion/Mountain Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer
      loads select your language and click on the Continue
      button. When the menu bar appears select Disk Utility from the
      Utilities menu.
2. After DU loads select your hard drive (this is the entry with the
      mfgr.'s ID and size) from the left side list. Note the SMART status
      of the drive in DU's status area. If it does not say "Verified" then
      the drive is failing or has failed and will need replacing. SMART
      info will not be reported on external drives. Otherwise, click on
      the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions
      from the drop down menu to one. Set the format type to Mac OS
      Extended (Journaled.) Click on the Options button, set the
      partition scheme to GUID then click on the OK button. Click on
      the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner.
If you have Snow Leopard Time Machine backups made while on Snow Leopard, then you may do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion/Mountain Lion files.

I have just installed Mountain Lion over Snow Leopard, I now can't open Photoshop?

Hi everyone, I have just installed Mountain Lion over Snow Leopard. The installation went smooth and woks well. Now I find that Ican't open either Photoshop CS or Microsoft Word. I upgraded in order to install Lightroom 5, obviously there is now an incompatability, is there a work around?

If that is the original Photoshop CS, and Word 2004 or earlier, then they won't open because Lion and Mountain Lion do not support PowerPC apps. They must be Intel code. Snow Leopard could run them because it included Rosetta, a PowerPC to Intel (and back) interpreter.
You have a few options.
1) Go back to Snow Leopard.
2) Update your apps to compatible versions.
3) If you have Mountain Lion because newer apps require it then:
a) Install Snow Leopard Server (currently being sold by Apple for $20) in a VM such as Parallels, and then run your PPC apps in the VM.
b) Install Snow Leopard on a separate partition and boot to that version of OS X when you need to use those older apps.
