Business Macintosh osx Snow Leopard

Installing OSX Snow Leopard on a 2012 Mac Pro 5,1

Yes, you possibly can install Macintosh OS X Snow Leopard on a 2012, Mac Pro 5,1 silver tower desktop pc. Web sites that inform you otherwise will not be wholly mistaken, they only don’t have all of the information.

Let me start by saying that I’m simply an peculiar Mac consumer, not a techno-geek, who simply upgraded from a 2006 Mac Pro 1,1 to a 2012 Mac Pro 5,1 — a big leap forward. And like many others who’re upgrading from the primary era Mac Execs, I’m accustomed to operating older software program, so I made it my business to study all the things I might about putting in OSX Snow Leopard and OSX Lion on the new Macintosh. Once I’ve received it set as much as mirror the place I’m proper now, I can install different operating techniques and transfer slowly ahead.

One among my favourite Macintosh web sites is the guru of Mac info… This web site helped me to make sure that my new-to-me (used) Mac pc is legit, and never a 2009 model masquerading as a 2012 as seems to be the large rip-off on the market nowadays. But that being neither right here nor there, here is what says about my particular mannequin: It came pre-installed with OSX 10.7.four which is Lion, but the 2012 Mac Pro 5,1 is “capable of booting Mac OSX 10.6 Snow Leopard.”

I can verify that assertion absolutely, because yesterday I efficiently put in not solely Snow Leopard, but a very previous recreation to test whether the computer would even accept an previous disk, not to mention install software program from it. The game, by the best way, was Tropico Mucho Macho from Pop Prime Software program and MacSoft, whose system requirements don’t even point out Mac Pro. This recreation requires a G3-G4 processor, and OS 9.1, or OSX 10.1.5 or larger.

OS 9 was the last operating system in use before OSX, and is usually known as a “Mac Classic” working system. OSX 10.1 is Puma, one of the earliest versions of OSX which got here out in 2001, if that tells you anything about how previous this recreation is. In other phrases, putting in the Tropico recreation is a wonderful check, since I know that it works on my Mac Pro 1,1 underneath Snow Leopard.

This is where it will get tough, nevertheless, on putting in Snow Leopard in the first place… the Mac Pro 5,1 refuses to simply accept the unique Snow Leopard 10.6.3 installer CDs. Right here’s what occurs whenever you first try and insert a Snow Leopard installer CD on a newer Mac Pro: nothing. You end up with a grey display of misery that takes you nowhere. It merely doesn’t work.

The trouble is that the one model of Snow Leopard that the 2012 Mac Pro 5,1 recognizes is an upgraded version. The installer disks are for OSX 10.6.3, but the pc only accepts OSX 10.6.eight. There are not any installer disks for the latter which is the place the confusion is available in, with web sites claiming that it can’t be finished.

And to complicate it additional, if the installer disk came bundled together with your previous pc as an alternative of being bought separately, then that Snow Leopard system gained’t work both. You could begin with a retail model of OSX 10.6.3 as bought off the shelf in a retail store. Thankfully I had one.

Snow Leopard is likely one of the few previous working techniques that Apple nonetheless sells, a curiosity in itself, so in the event you don’t have an installer CD from years in the past, you possibly can still purchase one brand new, but you’ll still want access to an older pc to transition it over.

The conversion course of isn’t straightforward, but I’ll stroll you through the steps that I took. First, you must have entry to a machine that recognizes the Snow Leopard 10.6.3 CD disk. There’s no means around that. I nonetheless have my Mac Pro 1,1 so I used to be good to go.

From the 10.6.three Snow Leopard installer CD, set up Snow Leopard on an empty partition of the older pc. This provides you a pristine version to start out with.

Caveat: The dimensions of this partition will impression your choices for shifting the operating system onto a USB thumb drive. My partition was over 100 GB, most of which was empty area. Had it been 7.5 GB even with empty area, the process would have been a lot easier. I do not know, nevertheless, if the operating system would have installed on the smaller partition, or if it’s attainable to even create a partition that small.

In my case, once I did the initial install from the OSX 10.6.3 CD to the previous pc, I didn’t opt for a minimal install. I let it set up all printers and so forth, and the top outcome was that it was too huge for the eight GB thumb drive. To be able to pare it down to fit on an eight GB thumb drive, I needed to manually remove fairly a bit of knowledge. I’m savvy sufficient to know what’s protected to delete, which for me fell into three classes: fonts, unused printers, and desktop footage. Had I opted for the minimal set up, maybe it will have been sufficiently small. I do not know.

Once Snow Leopard is installed onto the older pc, boot into that partition, and download the updater to take OSX 10.6.3 to OSX 10.6.8. Choose the 10.6.eight Combo update.

I do know of two reliable hyperlinks for this free replace: the Snow Leopard web page on Apple’s own website, and the 10.6.eight Combo Replace on Wikipedia, which downloads instantly from Apple’s website.

It’s a disk image, so double-clicking it should put a onerous disk on your desktop. Double-click that tough disk to get to the update, and launch the update. It can improve Snow Leopard 10.6.3 to version 10.6.8. In the event you don’t see the disk on your desktop, go to Preferences within the Finder menu, underneath Basic, and click on the field to point out arduous disks on the desktop. Click the packing containers for external disks, too, so that you simply’ll be capable of see the USB drive that you simply’ll be using to move Snow Leopard from the previous pc to the newer Mac Pro.

Reboot into a totally different partition so that Snow Leopard shouldn’t be the lively operating system. In case your USB drive is as huge as the complete partition that Snow Leopard is put in on, together with empty free area, you should use the Macintosh built-in Disk Utility in the Go menu underneath Utilities: Disk Utility.

If not, you’ll have to obtain a program reminiscent of Carbon Copy Cloner, which is the program that I used. The difference is that CCC ignores the free area and just clones the operating system information, whereas Disk Utility apparently elements the free area into its cloning mechanism. Carbon Copy Cloner is at present $40 with a 30-day free trial. Even should you succeed in the course of the free trial, you need to thank the creators with a buy, because they only saved your bacon.

The subsequent step is to organize the USB drive. In Disk Utility, select the USB drive from the left sidebar listing, and click the Partition button. There gained’t be a Partition button until you’ve chosen the primary USB drive and never a partition on that drive.

In the Partition Format selection, choose 1 (one) partition, after which click on the Options button on the bottom of the window. In Choices, select the “GUID Partition Table” or it gained’t be bootable. Click OK or Apply to create the GUID partition, and it will reformat the partition (and erase all the things on the USB drive.) Be sure that the Format is about to “Mac OS Extended Journaled.” You’ll see it in the Partition Info part. GUID and Mac OS Prolonged Journaled are two separate settings.

The GUID choice makes Snow Leopard bootable instantly from the USB drive. While this isn’t a requirement for shifting it over, it’s all the time good to have a bootable model of your operating system on a secondary supply. That method if your system gained’t boot from the interior disk, you’ll have an choice that permits you to boot from the USB to troubleshoot.

Once the USB disk is ready, click on the Snow Leopard disk in the left sidebar listing, and choose Restore from the Disk Utility buttons. That is the arduous drive or partition that you simply’ve put in Snow Leopard 10.6.8 on. Drag it to the Source subject. Then drag the USB partition to the Vacation spot subject, and click on Restore. It’s a bit convoluted because you’re not likely restoring something, you’re cloning one drive onto one other.

The method in Carbon Copy Cloner is nearly equivalent, except that it has checkboxes for what you need to copy over. If this was a clear set up, examine all of the bins. The very last thing you need to do is attempt to take away something manually which may render the system inoperable. If it wasn’t a clear set up, but as an alternative was a working drive loaded up with different software program, you may go into the Purposes folder at this point and uncheck software that didn’t come with the system. Again, go for caution.

Once it’s finished, go up to the Apple menu and Restart your pc holding the Choice key down on your keyboard. This brings up a listing of bootable onerous drives. Click on the USB drive that you simply simply put in Snow Leopard on, and reboot. This is merely to test that the system is useful, and can boot from the USB drive. In case you didn’t make the USB bootable by selecting GUID, you possibly can skip this step.

Once verified, reboot into the traditional working system so to eject and remove the USB drive. Now you possibly can plug the USB drive into the 2012 Mac Pro 5,1.

Because this is not technically an installer disk reminiscent of what came on the unique Snow Leopard installer CD, however a clone of the Snow Leopard system information, you gained’t boot from the USB drive on the Mac Pro 5,1. You may do it just to ensure it boots earlier than installing it, nevertheless. To maneuver Snow Leopard from the USB disk onto the 2012 Mac Pro 5,1, you comply with virtually the identical steps as before:

  • Launch Disk Utility
  • Partition the exhausting drive of the newer Mac Pro in the event you haven’t already finished so, choosing the GUID choice. It will erase every little thing on the arduous drive. Should you’ve been utilizing the computer and it’s already partitioned, you’ll be able to examine to just remember to partitioned it utilizing GUID by clicking the onerous drive (not the partition) in the left sidebar of Disk Utility, and searching at the Partition Map Scheme within the backside of the window. It should say GUID Partition Desk. NOTE: You can too do this on a separately installed inner arduous drive.
  • Click the USB drive partition, and the Restore button, so that the USB drive seems as the source.
  • Drag the 2012 Mac Pro 5,1 partition that you simply’ve set aside for Snow Leopard to the Vacation spot subject.
  • Click on Restore.
  • Then use Disk Utility to Restore Permissions on the newly put in system. They should be nice, nevertheless it doesn’t harm to ensure. This step isn’t crucial with commonplace installers, however shifting Snow Leopard onto a 2012 Mac Pro is just not a commonplace set up. 🙂

That’s it. Set Snow Leopard as the Startup Disk in your System Preferences, and reboot. You need to efficiently boot into Snow Leopard. From there, you’ll be able to set up your older Snow Leopard suitable software program.


  • Install Snow Leopard 10.6.three onto an empty partition of an older pc
  • Upgrade Snow Leopard 10.6.three to Snow Leopard 10.6.8
  • Clone (Restore) that partition onto a moveable USB drive
  • Clone (Restore) it from the USB drive to an empty partition on the newer Mac Pro

I partitioned my 2012 Mac Pro into 5 partitions, truly six however I didn’t use certainly one of them. I successfully put in the following operating techniques:

  • OSX Snow Leopard 10.6.8
  • OSX Lion 10.7.5
  • OSX Mavericks 10.9.5
  • OSX Yosemite 10.10.5
  • OSX El Capitan 10.11.4

The rationale that I needed so many various working techniques is that my current, working OS on the Mac Pro 1,1 is Lion. That’s where all my software lives and works. I also have software that I run in Snow Leopard, principally simply games at this level, I confess.

I do not know how nicely my software program will port forward, and some of it is costly akin to Photoshop and Quickbooks. Other software doesn’t have an upgrade at any worth, resembling Apple iWorks ’09, which was the final model that had absolutely useful desktop publishing capability.

As somebody who publishes paperback books, I can’t transfer to the stripped down model which followed iWorks ’09. For me to upgrade from this program means shifting to a utterly totally different program reminiscent of Microsoft Word, or one of many Open Source or shareware choices, though the latter options all have limitations so I’d in all probability end up switching to Word.

So the plan is to install my present software on Mavericks, and hope that it all nonetheless works there. If it doesn’t, I have the Lion system to fall back on while I work my approach comfortably forward. It’s a security internet. For that purpose, I installed every part on the OSX Lion partition of the 2012 Mac Pro, and can set up it once more on the Mavericks partition. I’m not prepared to move past Mavericks yet, but the choice is there and prepared.

As for information, all of my information are stored on a separate drive, not within the Paperwork or different local folders. I have an inner arduous drive, a utterly separate disk, only for information: graphics information, text information, Photoshop information, photographs, music information, spreadsheets, all of the information. That means they’re accessible from any operating system that I’ve launched, and they’re backed up individually from the working techniques. Also, should a system go bonkers and require a full exhausting drive wipe and reinstall, it doesn’t affect my knowledge, apart from mail.

In line with the Roaring Apps software program compatibility web site, there’s a excessive chance of success in shifting to Mavericks. My current software program seems to be suitable. Beyond Mavericks there’s No Knowledge for some of my purposes on the newer methods, so perhaps they’ll work, and perhaps not. Both method, I’ll report back to Roaring Apps so that they will replace info for the rest of you.

Did you catch the half where I’m an writer? When you consider in historic astronaut concept, listed here are two books that I’ve written on the topic. If historic aliens aren’t your thing, take a look at books that I’ve written or narrated within the sidebar of this blog submit. It’s a means of claiming Thank You! 😀
