Hard drive run OS X 10.6.8 and an added internal drive run OS X 10.8?

I want to run two OS X's on my computer so that I won't have to spend $1000+ to upgrade all my software. I have OS X 10.6.8 on my Mac Pro hard drive now but would like to add an internal hard drive that runs only OS X 10.8. Is this possible to do? If so, how do I go about it?

The Cheese Gratter Mac Pro (I used to own one), has room for four drive lots for 3.5" internal disk drives. It is rather easy.

Once the new 3.5" internal drive is installed, you then use Disk Utility to format the drive.
Disk Utility
select the drive on the left
Select the "Partition" tab on the right
Select "Options"
Specify GUID (this is needed if you are going to boot from this drive)
Click OK/Apply
Decide if you want 1 partition, or more. If more than 1, size and name each partition.
Click Apply
Now install your operating system. I would suggest making a copy of the "Install OS X Mountain Lion" installer, as the installer will delete itself when it is finished. If you make a copy before you install, it will delete the copy you are running, and you can use the original again if you need to re-install, or want to install Mountain Lion on other boot disks or systems you own or control (aka Family).
If you have created more than 1 partition, you can install other operating system versions on those partitions or use them for data.
You should have 2 more empty drive slots. You can add more 3.5" disks. If you have not been doing backups yet, I would suggest installing additional disks in those slots for backups.
Once you have your 2nd (3rd, 4th, 5th, etc...) operating system installed, you can use System Preferences -> Startup Disk to specify which operating system you want to boot the next time you boot.
OR you can boot holding the "Option" key, and the Mac will boot listing every bootable disk/partition and you can click on the partition you wish to boot from.
Hopefully, when you boot up via the "Option" key, you will see a "Recovery" Partition for the Mountain Lion (10.8). If you do not see a "Recovery" partition, you should start over and create 1 extra 2GB partition on the new drive that can be used for the Mountain Lion "Recovery" partition.

I have formatted my SSD and hard drive.... I am running a clean install from disk of 8.1 pro. I cannot determine if it is a compatibility

issue or hardware issue. I had run a memory test and scan disk for bad sectors from the bios. As administrator, I enabled automount in diskpart to allow windows to assign a drive name.
From the bios, I can see both drives and only the ssd. I have not pinpointed when the harddisk is unmounted. It is formatted as NTFS. I can hear it unmount either during boot or upon waking from sleep mode. The bios sees no bad sectors nor does windows.
However, when I had the intel compatibility software installed, my hard drive never mounted. I did a restart and inorder for windows to see my hard drive. I disabled the intel software for the 4th gen i7 processor. This problem is happening less often. I do
not think I have solved the problem. Intel or Windows... I think a bit of both.
If there is a software patch, please guide me to it. I am in school and use my laptop ALL the time. I believe it is a compatibility issue. I have attached this from searching intel's site for downloads and windows is up to date.
I am quite concerned because I can hear my harddrive unmount. It is labeled as healthy NTFS partition. I have checked for hidden volumes and done everything I know to do to check the integrity of the hardware as administrator. I have searched microsofts
libraries and forums and have done everything I can find as suggestions.
I have checked for malware, viruses, etc. My only clue this is going to happen is the hard disk spins up and I hear the fan, then I hear it unmount the drive. Of course, after unmounted there are other issues which I have ruled out as the cause of the problem.
Basically, I am experiencing a lack of swap space after my hard drive unmounts.
Any suggestions, are welcome! I would really like to know if this is a known windows issue. I should not have to disable intel's processor software. I paid for the features of the i7 and would like to utilise the processor.

Hi,
According to your descriptioin, I don't think this is system problem, it should be Intel driver problem. It would be contact Intel to confirm this issue whether this is their driver problem.

I'm running Final Cut Express 2. How can I move entire project and application from one internal hard drive to another? Ran out of space on one drive. Thanks.

I'm running Final Cut Express 2. My video project is 95% done and I've run out of space on my 500g internal hard drive. How can I (1) move the complete FCE program and video to my unused 250g internal hard drive and operate it from there and (2) how do I then purge all the FCE info from the 500g drive without losing anything from the 250 drive?
Also, is it possible to change the aspect ratio from 4:3 to 16:9 when the project is finished? If so, how? I now know this all should have been done before I started. Thanks for the help.

1. You can't move the application. It must remain on the system drive. Move your capture scratch folder to the external FireWire drive and use the reconnect function in the project.
2. What's the media 16:9 or 4:3?

I have a late 2012 iMac running osx 10.8.5. I keep losing access to my internal hard drive. I can reboot and regain access and it will last for a few minutes or hours. Disk utility does not seems to help.

I have a late 2012 iMac with an I5 precessor running OSX 10.8.5 and a 1tb internal hard drive. I keep losing access to the internal hard drive/startup disk.
I can reboot and everything operates as normal for a few minutes or hours but then I lose all access again to anything on the hard drive. The computer is still up and running but no files can be accessed and certain websites cannot be acessed even though internet access appears to be normal. Disk utility can only find permission errors related to iTunes which can be repaired only to come back at the next scan (I would not think permission errors would have anything to do with the hard drive crashing). It does not seem to matter what program I am using at the time access is lost and it can lose access sometimes right after reboot when no program is running.

You will need to boot into the Recovery Volume (command - R on a restart or hold down the option/alt key during restart and select it) to run Disk Utility/Disk Repair.

Sometimes my computer takes too long to connect to new website. I am running a pretty powerful work program at same time, what is the best solution? Upgrading speed from cable network, is it a hard drive issue? do I need to "clean out" the computer?

Many times my computer takes too long to connect to new website. I have wireless internet (time capsule) and I am running a pretty powerful real time financial work program at same time, what is the best solution? Upgrading speed from cable network? is it a hard drive issue? do I only need to "clean out" the computer? Or all of the above...not to computer saavy. It is a Macbook Pro osx 10.6.8 (late 2010).

Almost certainly none of the above! Try each of the following in this order:
Select 'Reset Safari' from the Safari menu.
Close down Safari; move <home>/Library/Caches/com.apple.Safari/Cache.db to the trash; restart Safari.
Change the DNS servers in your network settings to use the OpenDNS servers: 208.67.222.222 and 208.67.220.220
Turn off DNS pre-fetching by entering the following command in Terminal and restarting Safari:
defaults write com.apple.safari WebKitDNSPrefetchingEnabled -boolean false

Either of these should help.

Or search 'disk size' in the App Store.
Be carefull with what you delete & have a backup BEFORE you start, you may also want to reboot to try to free any memory that may have been written to disk.

I have a new Windows tablet computer with limited hard drive space, and cannot transfer my itunes library to the hard drive. Can I run t media from an external hard drive? If so, how do I transfer my files?

I have a new Windows tablet computer with limited hard drive space (32 GB), and cannot transfer my itunes library to the hard drive. Can I run itunes from an external hard drive? I have tried to follow some of the directions on this site, but am having no success. Thanks.

iTunes will run fine with the media on an external drive.
However, I suggest that a tablet computer with a tiny hard drive is not ideal as the primary computer for managing an iTunes library, even a small one. If you have another machine, perhaps a big, boxy, inexpensive old desktop with a decent amount of storage, that might be a better choice.

I am running 10.5.2 from a USB, I need to mount my internal hard drive, can anyone help me?

Hi everybody. My imac suddenly died on me. It couldn't start, right after the apple sign appeared, an interrogation sign showed. I ran the disk utility, and the problem was that the internal hard drive was not mounted. I installed the 10.5.2 (the one it came with the imac) in a USB flash drive, which I am running now. Is it possible to mount my internal drive so I can back up my data? (I know should back my data up regularly, but I didn't). Any help would be greatly appreciated.
Best regards,
Alvaro.

I suspect a failed HD, in that case I'd recommend Apple Hardware Test in Extended Mode at least 3x. You will need the original install discs that shipped with the computer, if you do not have them any longer you will need to order a replacement set from Apple by calling AppleCare. You will need a credit card and the serial number of the machine. The cost should be nominal.

Elements 6.0 won't run from my external hard drive?

So I had Photoshop Elements 6.0 installed on my laptop. Long story short, my laptop died. I removed the hard drive, put it in a case and turned it into an external. When placed into another working laptop, Elements runs just fine. However, when I hook it up as an external, it refuses to run. Because I didn't make an icon for PSE on my desktop, I have to go into Program Files and under PSE 6.0 and find the application icon for it and double click. A message pops up saying "Licensing for this product has stopped working. - You cannot use this product at this time. You must repair the problem by uninstalling and then reinstalling this product or contacting your IT administrator or Adobe customer support for help."
What gives?

If you take the hard drive and install it into a different computer and make this hard drive the system drive (i.e. the drive where the operating system is installed) then everything on that drive should work properly. If you take the hard drive and attach it to a computer that already has a system drive, nothing on that hard drive will work.
Mr Ellis had a more lucid explanation of this, but I'll add a bit to both of your treatises, hopefully this will add clarity, but who knows, anything can happen.
The >> BIOS << of a computer is responsible for the "boot order" of the machine. That is where the computer gets its instructions about where to look for the OS. If you summarily stuff a random HDD into a machine and expect it to boot from it, in most cases you will be disappointed. Since the drive didn't exist before, it likely won't appear first in the boot order, and gets ignored. So, to use any random HDD, you first would have to go into the BIOS and place it first in the boot order, then the computer would use the OS it found there to begin the session.
The trouble is, Windows takes note of hardware changes, and might ask you to reactivate Windows, when it realizes it is no longer in the original computer. Obviously the original hardware manifest is on the HDD being transported, and would be dramatically different from the hardware environment of the new machine.
In most cases, Windows will not perform up to expectations if it isn't reinstalled into the new host machine.
However you can retrieve the catalog file from the laptop HDD and place it in the new computer, and also copy the "My Pictures" folder to it. Since, in this case both the laptop "My Pictures" and desktop "My Pictures" are both likely on their respective "C:/" drives, in all likelyhood PSE would be able to open the catalog successfully.
I should add that in the case of running the OS from an external HDD, the first choice in the computer's boot order must be set to, "boot from USB device"!

How can I run a copy of photoshop elements from a hard drive from a broken laptop on my new imac

The laptop had motherboard issues so have taken the hard drive out and am running it externally on a new iMac - if i try to run the program it says error code 6 and that i need to uninstall then reinstall the product but I bought it online so don't have a disc

Install a downloaded version... you should be able to find it among the following links:
PSE 10, 11 - http://helpx.adobe.com/photoshop-elements/kb/photoshop-elements-10-11-downloads.html
PSE 7, 8, 9 - http://helpx.adobe.com/photoshop-elements/kb/photoshop-elements-7-8-9-downloads.html
Check your Adobe account online for the serial number if you have not saved it anywhere locally.

I uninstalled a cad program I've been running for years and when I go to reinstall it says 0kb available, but in Finder the hard drive shows 80 gb. Why won't it let me install?

Cad software started having some issues so I uninstalled it and when I go to re-install, I can't get past the "select folder for installation" page. I can't browse to any other than the default applications location and at the bottom of the screen it shows 0kb available. But there is 80 gb available on the hard drive. It's an older software, but that shouldn't really matter as it's been on the machine for years. Did upgrading to Snow Leopard somehow do this (as it had many other negative effects on the software)? Software is ArchiCAD 9. I'd upgrade to current version if I had an extra $4K laying around but I don't (so please don't suggest that). Also, I'm that Administrator and I don't have problems installing other softwares. Is it possible that the installation disk from the software manufacturer can have an expiration date? Software is from about 2006.
Thanks.

I suspect the software was originally designed for PPC based Macs and is simply not designed to run on 10.6.7. I would recommend contacting the manufacturer and asking the correct way to uninstall they're application.
After uninstalling I would run Repair Disk Permissions in Disk Utility and if necessary do a SMC reset using the following instructions:
SMC RESET
• Shut down the computer.
• Unplug the computer's power cord and all peripherals.
• Press and hold the power button for 5 seconds.
• Release the power button.
• Attach the computers power cable.
• Press the power button to turn on the computer.
PRAM RESET
• Shut down the computer.
• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

I have a 2007 Macbook Pro that is running 10.7.5 and I am trying to use a 10.6.3 DVD to install Snow Leopard to an external hard drive.

I have a 2007 Macbook Pro that is running 10.7.5 and I am trying to use a 10.6.3 DVD to install Snow Leopard to an external hard drive. I've followed every possible instruction on every which website. The problem is when I boot to Install disc, I am unable to choose which hard drive I'd like to install the OS on. It says that it is unable to Install and automatically takes me to Restore and suggests that I restore to Time Machine backups. Any and all help is appreciated.

lovinlife5959,
have you tried booting from the grey Mac OS X Install DVD that originally came in the box with your MacBook Pro? See if you can install its version of Mac OS X (either 10.4.9, 10.4.10, or 10.5.0, depending upon when it shipped from the factory) onto your external hard drive. If that works, boot from your external hard drive, run Software Update on it, and then try updating your external drive to 10.6.3 via the white Snow Leopard DVD.

How can I access Address Book data from an older version of the application to transfer it to a newer version of Mac OS running on a second hard drive on the same MDD G4?

I installed a hard drive from one PowerPC Dual 1.25 GHz MDD into another one with an older version of the OS X. all my Address Book data are on the older hard drive, from which I now boot the computer. When I launch Address Book as an app on the hard drive with the newer version of the OS, I get an error message that says I cannot run the version of Address Book from the older hard drive on the newer OS. How can I access the data on the older hard drive version of the Address Book app so that I can transfer it to the newer version of the app on the boot drive? The "Import" functionality will not work. I will be grateful for any help I can get. I would also like to uninstall the older version of OS X from the older hard drive.

Boot from the older version of OSX, then in AB use the File>Export>Export vCard after selecting all in AB.
Then boot from the new OSx & use the new AB to import that VCF file.

Macbook Pro 2010 Running Slow and Pulse/Click Noise (Not Hard Drive)

Hello. My 13" Macbook Pro mid-2010 (7,1) suddenly began running slow and lagging on certain operations. There is also a light pulse/click noise coming from the center of the keyboard. I am sure this is not a failing hard drive. How, you may ask me, am I so sure??? Well, I originally thought it was a failing hard drive and so replaced the hard drive, and there was absolutely no change, and the lagging and noise still continues. This makes it very frustrating to do basic, low-memory-intensive things like browse on Safari or watch a movie.
I have upgraded to Mavericks, and have 8gb Ram. This problem started suddenly about a month after upgrading to Mavericks. In fact right now my computer is lagging just typing this, Activity Monitor says I am only using 2.75 ram of 8gb.
Steps I have taken with no resolution
-Replaced the hard drive
-Reinstalled OSX Mavericks
-Verified and Repaired Permissions (I still get a message the the following item can't be repaired "System/Library/CoreServices/RemoteManagement/ARDAgent". But I have read that this is a common thing and can be ignored.
-Restarted the computer holding down left shift-option-control and the power key for 10 seconds (not sure exactly what this resets, but some type of system cache thing.
-Reset the PVRAM stuff ( I restarted the computer holding down command-p-r. I'm not sure I did this correctly as it went to the firmware disk repair screen.
Could there be a RAM issue? Does RAM start making noise when it goes bad? I bought my upgraded ram from ebay, it isn't the official Apple Store stuff. Could replacing the ram possibly help? My System Report tells me the RAM is OK.
Putting a message on here for help is the last step before giving up. I can't do much with this computer because it is hiccupy and overall difficult.
Thanks.
