I have a dual core mac pro tower , can I upgrade to lion from snow leopard?

The 2006 and 2007 Mac Pros can be upgraded as far as Lion. Mountain Lion can be installed on Mac Pros from 2008 onward. See below:
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard — Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service — this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion — System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) — Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) —
             Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) — Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) — Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) — Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) — Model Identifier 3,1 or later
         7. Xserve (Early 2009) — Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Are my applications compatible?

There is no Mobile Me anymore. It has been gone for several years, now. However, your existing calendar and mail will integrate with iCloud if you enable it on your system.

Can I upgrade a computer from Snow Leopard to Lion by using an already upgraded account? I have multiple computers on the same account.

I already have an upgraded desktop, but I also have a MacBook Pro that I want to update from 10.6.8 to 10.7. They are registered under the same account, but the MacBook Pro is under a diferent email. Is there a way I can use the software I have on my desktop to upgrade the MacBook Pro, or do I need to take it to an Apple Store?

Launch the Mac app store on the computer you want to update.
To use your Apple ID at the Mac App Store
Choose Store > Sign In from the App Store menu.
Enter your Apple ID and password, then click Sign In.
Then redownload Lion.

Installed Memory not showing up in a late 2009 Dual Core Mac Pro

I have a late 2009 Dual Core Mac Pro.
I restarted the my computer today, an a utility popped up saying something about I need to re-arrange the memory in my mac because it was not optimized.
I thought this was weird because all the slots are filled with 2 gigs chips for a total of 16 gigs.
When I checked about this Mac it said I only had 12 gigs of memory in my system.
I went to open up the case, and there are to red light glowing for slots 7 and 8 on the motherboard, and any memory chips I put in those slots do not show up.
Can anyone tell me what is going on and how to fix it.
There was a power outage the other day, but I keep my machine on a surge protector.
I generally try to take really good care of my computers so seeing something wrong out of the blue like this is a little freaky for me.
Any help would be great.
Thanks
Stan

Each "side" is operated independently, so slots 1, 2, 3 and 4 are one set, and 5, 6, 7, and 8 are an independent set. The third and fourth slots on each side share a memory channel, so a failure of one module in these two slots could possibly disable the other one.
The Mac Pro uses the Error Correction Code hardware built into its Xeon processor to provide single-bit (in a word) Error Detection and Correction in Hardware. It also can detect double-bit errors, but these cause a kernel panic, machine-check, error overflow or uncorrected error. This is by design, to avoid poisoning you data.
The Error Correction Code hardware is used in a special way at Startup. Any failure (correctable or not) that occurs in the first few seconds while running the Power-On Self Test causes your Mac to declare the slot(s) of those modules "empty" and simply not use them in the running system. Vigilance is required, because the next time you run this test, those Bad modules may pass.
So the movie version is that you have some DIMM(s) that have failed, and you should remove them from your Mac and consider whether to replace them with good modules, or to add some larger modules.
I expect your recent power failure, protected by a UPS, is merely a coincidence, not a cause-and-effect.

I have a pre-2008 Mac PRO how do I upgrade to Mountain Lion?

I have a pre-2008 Mac PRO how do I upgrade to Mountain Lion? On the Apple's site on upgrading (http://www.apple.com/osx/how-to-upgrade/), I see that "Mac Pro (Early 2008 or newer)" is required for the upgrade. What's up with that?
Will upgrading of the GPU do the trick?
I'm curretly on Snow Leopard, will I be limited to Lion?

Which model of Mac Pro Tower can take 64BG RAM?

Hi everyone,
Been searching and going around in circles to find the true answer to this so I figured I'd just make this post.
EXACTLY which models of Mac Pro Tower can take 64GB of RAM. Looking on websites like OWC and asking people and I'm getting conflicting information and getting confused.
THANKS!

1. Yes.
2. Yes; Apple doesn’t update its specifications when higher capacity RAM becomes available. A few models require more recent firmware versions and/or OSes installed to reach the actual limit.

Negative reviews are common place here as it is a trouble shooting forum. If you want to read the advantages, improvements and new features then go to the Apple site. If you are running Word 2004, Early Adobe suite, etc which are PPC programs, then don't update. Go to Apple logo in upper left menu bar, open About this mac > More Info > Software >Applications and sort by 'Kind' and look what PPC programs you have installed. If you are not prepared to upgrade these programs, then do not update to Lion.
There are plenty of threads to read up on about this here. But remember that 99.9% of comments will be negative, even though the forums represent only a tiny fraction of the Millions of Lion Downloads purchased and installed with no issues at all. So basically it's your call.
Good Luck

I no longer have a PC or Mac. How can I upgrade to iOS 5?

Your iPhone can be updated to the latest firmware in an Apple Store but you would lose all the information off your phone.
If your happy to do this, may I recommend backing up to iCloud once you are on iOS 5.1.1 and then you will be able to perform future upgrades over wifi and restore your phone from your iCloud account should you ever need to in the future.
The other option might be to back your iPhone upto a friends computer without syncing and this might be the only way you could restore everything back onto your updated phone.
Also download apps to back up your contacts online so that you can restore them also after the update.
May I suggest Contacts Backup app which enables you to back up your contacts by email, Dropbox or via USB.
Hope this helps.

Hello, I have upgraded my laptop to lion, from Snow Leopard, but now my Music Pad Pro, program will not work , can anyone help? Thank you.

Hello, I upgraded my laptop from Snow Leopard to lion, unfortunately I have a 2 music programs that no longer work. one is called the Music PadPro, which is now gone bankrupt, can anyone help?. I was talking to the Apple Store earlier and they said if I upgrade to the mountain lion it may help but I'm not so sure,
kind regards
Nigel

There's no reason that upgrading from Lion to Mountain Lion would make this application work. I've looked up Music PadPro. I don't know much about it, but it looks pretty old. Here are the requirements:
Macintosh G4 or higher processor running Mac OS X Version 10.2.6 (minimum),
Mac OS X Version 10.3.2 (recommended), or Mac OS X Version 10.4.2.
Looking at that, I would guess that the application would require a PowerPC processor. After the release of the Intel machines back in 2006, Apple included something called Rosetta within OS X. This allowed programs developed for the older architecture (PowerPC) to run on the newer Intel machines. The reason for this was to give developers some time to upgrade their applications to run natively on Intel processors. It was only with the introduction of Lion that Apple pulled Rosetta from their OS. They had basically given developers about five years to upgrade their applications. Unfortunately, in your case, the developer went belly up. You can always install an older version of the OS on either a separate partition or an external drive and you can run your program from there.

Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

I recently upgraded to Mavericks from Snow Leopard. Does Snow Leopard still exist on my Mac? If so, is it possible to restart under Snow Leopard in order to run PowerPC apps? If not, is there an OS available in 64 bit that supports PowerPC apps? Mav ***.

I recently upgraded to Mavericks from Snow Leopard. Does Snow Leopard still exist on my Mac? If so, is it possible to restart under Snow Leopard in order to run PowerPC apps? If not, is there an OS available in 64 bit that supports PowerPC apps? Mav ***.

The only reason I upgraded to Mavericks was because my Snow Leopard OS was 32 bit, which I was told would support only 4GB of RAM.
That wasn't quite right. You can put in as much RAM as your Mac's hardware supports. The division is in the apps themselves. A 32 bit app can't use more than 4 GB or RAM. A 64 bit app can use much more.
For example, as a 32 bit only version, Photoshop CS3 can't use more 4GB of RAM, no matter how much you actually have installed. CS4 or later can use all the RAM you want to throw at it.

Use the manual methods.. but it is possible for TM to wipe the old files in trying to fit into the space.

Upgraded my macbook pro to mountain lion from snow leopard does this mean i can upgrade my imac as well for the same price? And will it mess it up?

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.
