install Snow Leopard on New Mac Pro

I know there has been some discussion of installing Snow Leopard (SL) on a newly purchased 2010 Mac Pro that now comes shipped with Lion. I had to do a lot of legwork to come up with an actually very easy solution. I HAVE to have Rosetta and for Apple to not include this with Lion is truly unconscionable. I and many other make user have programs that we use every day that are not Intel.


Apple cannot tell you that you can install SL but it is actually very easy. Here is what I did:


When I received my brand new Mac Pro (MP) 3.33 (2010 model), I swapped out the main drive with an OWC Mercury 3G 240 SSD. I put my Lion drive to the side. I then booted the MP in target mode (just retsrt and hold down the "T" key). When booted into target mode, I plugged it into my Intel Mac Book Pro. You can use any Intel Mac though. I then plugged the MP into the Mac Book and the MP SSD showed up on the Mac Book Desktop. I reformatted the drive (1 partion but you can have more) and installed the SL 10.6.3 install disk into the Mac Book. I told the installer to install the drive on the newly formatted SSD that is present on my Mac Pro desktop. I installed SL to this target drive with no problem. The computer then restarted -- this is standard so don't be alarmed like I was. Once rebooted, I went through the first time user process I then installed the SL 10.6.8 Combo updater to the SSD.


I was then able to boot into the MP with no problems. To be safe, I then re-ran the 10.6.8 Combo updater and restarted. I then installed all the other updates for SL 10.6.8. I repaired permissions and that was that. DONE!


Now my brand new (1 week old delivered on 4/10/2012) MP 3.33 is FLYING with SL 10.6.8, an OWC SSD and Rosetta. I could not be happier!!


I have the Lion drive as a back up or if I need to call Applecare.


Please tell me if you have any question

Mac Pro, Mac OS X (10.6.8)

I agree: best to dual boot and use Snow Leopard there, unless you need to work with both environments concurrently.


Such as working with graphics from one PowerPC app, such as Freehand MX and cut & paste to a more modern app, such as Adobe Creative Suite.


Freehand MX running in Snow Leopard Server installed in Parallels 8 running in Coherence Mode in Lion:

My solution for that condition is rather simple.

I produce Copyrights and Patents (intellectual property) and US Government very rudely classified me for life.

The rules are, no classified or potentially classified or sensitive materials can be produced on a computer that has ANY network connection.

How is that a "simple" solution?


The software I use that is PPC only can be run using Rosetta and Rosetta can only be installed under Snow Leopard.

Still doesn't sound simple.


It IS simple.

I do require software updates like anyone else, which means a network connection must be established.

ALL of my personal files are on a separate internal hard drive that is physically removed prior to any software update or network connection.

Every other "file" is OS or Application and installed on its own separate hard drive. (be it SL or ML)

One hard drive is OS and Applications ONLY.

One hard drive is Files ONLY.


Under Rosetta I can copy and paste and "modernize" any file that is created under a PPC application.

Once "modernized" I have access to the files under either Snow Leopard or Mountain Lion.

The internal hard drive that has ALL my personal files is accessed by Snow Leopard or Mountain Lion.


I am attempting to modernize ALL my files away from PPC but did run into apps that only run under PPC and are not updated and are not going to be updated. (in fact, one app is no longer produced for the Mac at all)

These apps are CAD/CAM and Scientific graphics programs and are available for the PC with the exception of my PCB program in which I have 20 years of work invested.

The final result is that I absolutely required Snow Leopard.


All other solutions are easily handled through use of Boot Camp or Parallels.


For what its worth, I do use Adobe Creative Suite (CS6) in some of these processes.

Because the Mac Pro can handle up to 10 internal drives, I have no need to run any OS concurrently with the exception of Windows and even then rarely concurrently.


I will give some advice when working with Mountain Lion on a Mac Pro using this simple technique.

DO NOT boot either SL or ML with another OS internal hard drive installed.

It will work, however, Mountain Lion gets rather confused when using its "open with" contextual menu.

It is best to run one OS at a time with the other OS hard drive removed.


In both cases of OS, the background File Index process enters an endless "DO LOOP" if either OS hard drive is mounted while running the other OS. (does not produce a crash but is endless upon each new alternate mount)

May 24, 2013 12:38 PM in response to TOAO

"Open with" is funky even when other instances of the presently booted operating system are on other mounted volumes. If this is especially problematic with competing operating systems, then they can each be set up to not mount the other volumes upon booting. The application "TinkerTool System" does this conveniently, but it can also be scripted.

Removing the hard drive containing personal files during network connections for software updates doesn't protect your personal files from ambitious spyware acquired during the network connection. That spyware copies your personal data to the system drive and waits for your next network connection for software update to send your personal files to whomever.

May 27, 2013 8:55 PM in response to dcouzin

For spyware to "spy" on your files, the files MUST be present on your computer.

IF.... under the rare condition that a spyware is installed during system and application updates (very rare) then the spyware has NOTHING to spy upon except Applications and Operating system at the time of install.


Once network connection is removed, the spyware CAN "spy" upon your files but the "spying" accomplishes NOTHING because the spyware must "report" to the network to be spyware.


Once a network connection is reestablished, ALL the files "spied" upon have vanished because the hard drive is physically removed.

The spyware has NOTHING to report and most certainly cannot transfer any file because the personal files cannot be accessed.


The only plausible exception to this simplicity is a spyware that duplicates your personal files ON the System Hard Drive.

In that case, a massive increase in System Hard Drive volume becomes blatantly obvious.


In the case of people who are classified, it is a responsibility to maintain no less than two computers.

1. Not network connected.

2. Network enabled upon demand.


The network enabled machine has anti malware software installed and updated.

The network enabled machine downloads ALL possible updates to Applications and System MANUALLY.

These manual downloads are scanned for malware then MANUALLY installed in the machine that is not network enabled.


This works in 98% of all cases but not "all".

Some software applications do not have manual download services these days and can only be updated online.

In that case, the network enabled machine installs the update first then a system scan is performed.

If all is clear, the network disabled machine is connected.

THEN, the updated hard drive is removed and scanned externally prior to connecting the Files Hard Drive.


In most cases, an external system and applications only drive is updated.

Then the hard drive is scanned and if all is clear, the external OS/APP hard drive is simply cloned on to the network disabled machine.


No computer is totally immune to malware or hackers, however, the Mac is the least susceptible choice and the reason I use a Mac.

Since I do not have any internet habits that expose me to malware and do not use my network disabled machine on any network, then I comply fully with classification rules and guidelines.

(in other words, felonies commited upon me via malware are not due to my error or non-compliance)


Final note.

I have been using Leopard (10.5) for a very long time. It has ZERO updates to system or applications.

Snow Leopard is now in the same boat. There are extremely few updates and no reason to make a network connection.


In actual practice.... every important update to system or application has been accessible via manual download and is manually installable.

There has been no need for a network connection.


Mountain Lion on the other hand, is a stew in the making.


I have ten Macs, the machine I am using right now is totally sacrificial. (an old used Mac I bought just so I could do research and shop online without worry and quite frankly.... learn something)


So.... if you wish to protect yourself and your intellectual property, that is how to do it.

(makes no difference if you are classified or not.... and yes.... it is a tedious pain in the hiney and COSTLY)


So, I must respectfully disagree with your statements.


COMICALLY....

Who in their right mind keeps "personal data" on their machine????

Even my registered admin account contains useless fictitious information, ha, ha, ha !!!!

May 28, 2013 4:45 AM in response to TOAO

I perhaps wrote too succinctly. By "that spyware copies your personal data to the system drive" I meant "that spyware, later running on the system drive when the non-system drives are reattached, copies your personal data to the system drive." By "personal data" I meant the sought data from your "personal files" (your expression). We don't know what kinds of high secrets your personal files possess, but most spy-sought personal data is not voluminous. Although the data might be lodged in big files, the ambitious spyware can ferret it out and hide it within the fat of system files.


The point is that you are not complying with the rule "to not produce "sensitive materials ... on a computer that has ANY network connection" by temporarily rearranging the computer so the production (or storage) does not occur WHILE the network connection occurs.


Isolation from danger isn't simple. Consider the phenomenon of urininating into an infested place and having the infestation thereby reach you. It depends on the upstream velocity of the micro-culprits. Likewise, the spyware example depends on the ambitiousness of its writers.

May 28, 2013 5:48 AM in response to dcouzin

I was aware of what you meant.


The mandate is, no materials produced on a Network Attached computer.

In my case there has been no network attachment because my updates have been manually installed and scanned.


This process is identical to those processes used at classified installations that use consumer computers and operating systems.

In short, all "updates" are downloaded and scanned prior to distribution.

The updated "sacrificial" is also scanned prior to any distribution.

In the past.... updates could be obtained via optical disc and this made things far more secure.

Today, this security is compromised and requires extra steps because convenience is demanded.


The common "spyware" makes no "copies" of your files, it transfers files to a network.

The spyware simply makes an index pointer that points to existing files of interest.

If these files are not present at the time of network attachment, the "pointer" is useless.

Insidious spyware uses your OS file index as a pointer thus making itself virtually invisible.

Once again.... your OS file index is totally useless if the files are not accessible.


Files that are actually classified are never accessed by a computer that has a network connection.

This creates a restriction.

The computer used to produce or access these materials must be fully updated prior to use and never updated.

This sounds difficult, but its not.

You simply use an OS and Applications that require no updates to function properly.

Two ways to do this.

1. Don't use OS or App that has debilitating bugs.

2. Do not attach a File drive until the OS and Apps are debugged.


Using either method, once the OS and Apps are installed and or updated, the machine is never network attached.

The vast majority of professional software suppliers do not allow their products to be distributed with debilitating bugs and virtually all "updates" are merely enhancements.


For example.

Install Snow Leopard and update it without making a network connection. (very easy)

Install Adobe CS4 and update it without making a network connection. (very easy)

From that point forward, there is no reason to make a network connection because there are no updates required to achieve full complete and reliable operation.

Repeat process for all other Apps.

Once the File drive is finally attached, there will never be a network connection required.


In practice, some adaptability is required depending on situation.

For example, Adobe CS6.

This is fairly new software and it is assumed that some minor fixes will occur over the course of a year post release.

Here is the restriction.

The File drive is never attached for a period of at least one year.

You guessed it....

Two computers minimum are required and the primary computer sits and does nothing for a very long time in the case where new version software is applicable.


Case in point.

I bought a brand new top of the line fully loaded Mac Pro and monitor nearly a year ago.

It has yet to be used at all.

In the meantime, I use my other Macs that are never network attached to produce materials.


The issue of spyware is a mute point In My Case, HOWEVER, keeping your personal files on an external or removable hard drive separate from your OS drive is good advice for all and it is SIMPLE.

The side benefit is that smaller faster SSD drives can be used as OS drives because the volume required is minimized if personal files are kept separate. (a technique optimized by use of a Mac Pro)


Those who use their computers primarily for all things internet rather than what they were originally designed for is no concern of mine and those people ARE the vast majority.

They are the victims of malware by their own hand.


So, once again, I respectfully disagree with your statements, they are not fully informed.... and please!, don't play prosecutor.... you called me a liar by accusing me of "not complying" for no good or valid reason.

I am not selling anything, I am actually sharing some good advice.

May 28, 2013 6:35 AM in response to dcouzin

Just for the sake of conversation.

My "compliance" required some research into the Apple OS with regard to the Mac Pro.


The final result is a Bug identified in Mountain Lion and to some extent Snow Leopard.


The new Mac Pro has built in network transceivers.

In the past, these transceivers could be physically removed.

What this means is that ALL wireless network transceivers must be disabled for the Mac Pro to be used as a secure computer.

Sounds easy enough, simply set ALL network transceivers to disabled in the Network System Preferences.


This is where the Bug was discovered.

When Snow Leopard is started, restarted, or woke up from sleep, ALL network transceivers are enabled regardless of Network System Preferences.

This problem is addressed by Manually applying the Network settings each and every time the computer is started, restarted, or woke up from sleep mode. (very annoying)

The software (GUI) reports that the transceivers are disabled, but the transceivers are actually enabled.


Mountain Lion is a different story on the exact same computer.

The exact same thing happens as with Snow Leopard but with a twist that has no "easy" solution.

When running Mountain Lion, ALL network transceivers are enabled into standby when the computer enters sleep mode. (not present in Snow Leopard)

There is no "fix" except to never let the computer enter sleep mode while running Mountain Lion.

This Bug is a security breach waiting to happen. (all methods and settings of disabling the transceivers were tested)


Yes I contacted Apple.

Apple did not deny that this is a Bug and verified that it is a Bug but refused to address this issue because those who demand a "secure" computer are the absolute and most rare minority and the majority demands virtual instant network access at all times.


No offense, but perhaps you now see that my "compliance" is extensive?


Once again, I am sharing information that is useful to anyone concerned about computer security.

If you are using Mountain Lion, the only time it is "secure" is when it is powered off.


Eventually.... this issue leads to OS mandates imposed by the NSA, and that is a good place to stop asking questions.

May 28, 2013 7:02 AM in response to MlchaelLAX

I am sure you mean well.


Truth is, I did start a thread. (last I checked, only one reader was concerned or interested)


The topic of a separate file drive is useful for those who run more than one OS one their new Mac Pro's, specifically Snow Leopard and Mountain Lion and is applicable to that topic.


If you have an "axe to grind".... you speak for yourself.

Those who have an "axe to grind" make uniformed statements, make accusations, and play semantics word games.


You accused me of non compliance and proclaimed me ignorant.

None of which is valid, factual, or reasonable.


Now you intend to insult me further?

Interesting.


In Response to yet another "axe grinding"....

You asked, "what does that tell you?". (it is the only question you asked and it is dripping with disdain and contempt and prosecution)

It tells me that very few people are concerned about their computer security and even fewer are classified.

This is typical.

Since Apple confirmed this Bug, any debate upon its existence is mindless. (you can prove it yourself)


Oddly you made yet another uninformed statement with regard to sharing what I learned about protecting intellectual property by stating that I had not started a thread.


This is supposed to be a technical forum.

Your opinions and judgments do not belong here. (neither do personal attacks)


There, as requested.... I just spoke for you.

Feel better now?

I just allowed myself to sink to your competitive level.

Forgive me. (this is not beneficial or informative)

May 28, 2013 1:54 PM in response to MlchaelLAX

Obviously your quotes regarding this recent series of responses is irrelevant.

I must be confused.

I did not start ANY debate and shared nothing but facts. (with noted exception asking forgiveness)


Thanks, for calling me incompetent and confused, (a liar) what next, crazy? (this is very amusing)


My suggestions for computer security are factual and effective.

As an act of Good Will and Respect I shared them.

They are also helpful with regard to the Mac Pro mid 2012 that has no Snow Leopard install or system install disc supplied. (Mountain Lion only and only online)

The simplest solution is to keep non system files on a separate hard drive for access to both operating systems.

Makes no difference if you create intellectual property or not.

For the less than 1% of people who are classified, the software Bug Is a concern.

Because of that concern and software Bug, there may be people who require that Snow Leopard be installed on their "New Mac Pro" regardless of how extremely few in number these people may be. (Mountain Lion is Not secure)


With regards....

You can lead a horse to water, but you can't make it drink.


Best of luck!
