Will Snow Leopard (x64) allow my iMac to address more than 4 GB of RAM?

I just finished reading the specs on Snow Leopard and it's early release this Friday. Will the ability to address more than 4 GB of physical RAM work on all supported platforms, or just new systems? I'm maxed with 4 GB now, but would love to turn up the power!

Since your question is about a MacBook Pro, and this topic is in the Intel iMac category, you should go to the relevant forum, in this case probably this one
http://discussions.apple.com/forum.jspa?forumID=1293
and click the +Post New Topic+ link to create your own topic where other MacBook Pro users are likely to see it.
My guess would be that it makes no difference, because these overall RAM limits are based on hardware limitations, not OS limitations. A Mac Pro was able to access 32GB of RAM back when Mac OS X was Tiger (two revisions ago), because its more advanced CPU and hardware architecture made it possible (not the OS).

Will new Intel "Conroe" chip in Mac towers support more than 4 gig of RAM?

Hi all,
long time no speak
Question:
Will the new Intel "Conroe" chip in the upcoming Mac towers support more than 4 gig of RAM?
I score Orchestral and since the new VSL library is completely 24bit i need to at least be able to adress 8 gig of RAM (16 gig would be better
To APPLE: Guys please be aware that us Pro Users were always eager to adress those 8 gig of RAM in our G5s, but were dissapointed in the fact that Logic FCP etc, were never turned into 64 bit apps.....so adressing 4 gig was it for us........
I guess another way to ask the same question would be whether "Conroe" is 64 bit, as that is what is required to adress more than 4 gig of RAM.....
thanx,
SvK

From what I've read Conroe will be 64-bit. A google search of "64-bit conroe" will give you a few sources and more info.

It doesn't need to be a 64-bit application. It just needs to have 64-bit memory addressing. Here is a good article if you're interested.
http://developer.apple.com/business/macmarket/mathematica.html
I don't have any experince with VSL, but I did have a quick experience with Kontakt 2 (I sold it). The Kontakt 2 forum has a post from the moderator that explains some issues around Kontakt's memory issues.
http://www.nativeinstruments.de/forum_us/showthread.php?t=31572
"furthermore, even Kontakt 2 and related products will not get 64 bit support any time soon since this would require a complete rewrite of the engine - this is the last thing we want at this point! products based on Kontakt 2 are Akoustik Piano and Bandstand."
The complete rewrite of the audio engine might be the general issue with utilizing more than 4Gb of memory. But, I am not sure...I think there is another issue with how the OS handles memory usage.

That's what we needed.
Officially your iMac--known as a "tray-loader" for its optical drive type--can go to Panther (10.3.X). Panther is quite better than Jaguar (10.2.8) that you now have. You probably need more RAM than 160MB for even Jaguar. I feel that 384MB is about min for that OS.
The big problem is that the early iMacs came with painfully small hard drives --4 to 6 G--and OSX need a lot of free space on the disk for efficient performance. It's hard to keep a Jaguar system under 2G with a few useful apps installed.
Bottom line: you'll spent money for a hard-to-find retail OS install disk, more RAM, and a bigger hard drive, and you'll still have a slow computer that will always struggle with modern web pages. If you want to upgrade and experiment as a hobby or learnign experience and you can afford the parts and time, by all means--go for it. However, if cost is an issue, throwing money at this unit is not cost-effective in terms of how much more yo ucan get from it.

Is it possible to use Snow Leopard on Mountain Lion iMac with Virtualbox ?

I've been lucky recently, with people giving the perfect solutions for me so I try again.
But, this one is a tough one: How to run a virtual Snow Leopard on a new iMac ?
I got a 2013 iMac with Mountain Lion (10.8.5 now) so, totally incompatible with Snow Leopard. I need SL anyway.
Give up all you old applications and buy new ones is not acceptable. First, this is not my way of thinking and, second, some cannot be replaced.
Many posts say that you can use Snow Leopard with VirtualBox but I could not find anywhere the "how to" (in this particular configuration).
For instance, I followed these 2 protocols, almost similar:
http://www.maketecheasier.com/install-mac-os-x-snow-leopard-in-virtualbox-on-win dows/
http://www.macbreaker.com/2012/02/snow-leopard-virtualbox.html
but they use Windows as host system and something is not working (for me) with Mountain Lion.
I made many attempts, with VirtualBox 4.2.18, using pretty much everything: Snow Leopard DVD, SL Server DVD, .dmg of both. I've also got Combo 10.6.8 updates for both (but I'm not sure if it can be used before installing). With another MacBook, I managed to install a SLS on external hard drive and update to 10.6.8. Was unable to use it anyway.
Inevitably, I ended up with the message:
"FATAL: No bootable medium found! System halted."
I have no idea of what support to use and even, probably important, if it should be set on Primary or Secondary Master ? (in Settings / Storage)
Is it possible at all ???
Would it work better with VMware Fusion ? Anybody successful ?
Help
Thanx

How to install and run OS 10.6 Snow Leopard on a virtual machine on top of OS 10.7 Lion:
http://osxdaily.com/2011/11/17/install-run-mac-os-x-10-6-snow-leopard-in-virtual -machine-on-lion/
From kappy:
Clean Install of Snow Leopard
     1. Boot the computer using the Snow Leopard Installer Disc. Insert the disc into the
         optical drive and restart the computer. After the chime press and hold down the
         "C" key. Release the key when you see a small spinning gear appear below the
         dark gray Apple logo.
     2. 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.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, set the format type to Mac
         OS Extended (Journaled, if supported), then click on the Partition button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will require a restart after
         which you will be running a fresh install of OS X. You can now begin the update
         process by opening Software Update and installing all recommended updates to
         bring your installation current.
First you will have to prep your new SSD:
Drive Partition and Format
1. Boot from your OS X 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. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.

There shouldn't be need to reinstall OS X fresh unless your having file structure issues which if they are should appear when in the Steps, which then a zero erase and install will cure as well as any bad sector issues, the defrag step wouldn't be necessarry on a freshly installed system obviously as the files are written all together, not in portions all over the drive.
Hope this assists.

I'm attempting to install snow leopard on my 2008 Imac and it stops installing less than 1/4 way through?

I'm attempting to install Snow Leopard on my 2008 Imac and before it 1/4 way done installing, it ejects the disc and restarts the computer. Is there something I am doing wrong?

See:
How to Install OS X Updates Successfully
A. Repair the Hard Drive and Permissions:
Boot from your current OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities menu. 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 installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
B. Make a Bootable Backup Using Restore Option of Disk Utility:
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
C. Important: Please read before installing:
If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update. While the installation is in progress do not use the computer.
D. To upgrade:
Purchase the Snow Leopard Retail DVD.
Boot From The OS X Installer Disc:
Insert OS X Installer Disc into the optical drive.
Restart the computer.
Immediately after the chime press and hold down the "C" key.
Release the key when the spinning gear below the dark gray Apple logo appears.
Wait for installer to finish loading.
E. If updating:
Download and install update(s)
Use Software Update, or
Download standalone updater(s).

My MacBook (10.5.8) is very slow and has significant problems loading will Snow Leopard (10.6.3) help or make my computer slower?
Also why does my Macbook make so much noise (The noise concerns me because it is so loud it sounds like the laptop will break down or something at any point)?

It depends on your Macbook model how to open the bottom case.
Anyway you need to open up the buttom case or keyboard panel to access the CPU fan like following.

Does Snow leopard work on my iMac G5?

Does Snow leopard work on my iMac G5?

Before upgrading to Leopard, be sure to determine if you need Classic. You won't have access to Classic, unless you erase and partition your hard drive:
http://docs.info.apple.com/article.html?artnum=61301
Or use an external Firewire hard drive to run 10.4.11 or earlier. Boot Camp is not available to iMac G5s. iTunes 9.2.1 offers some compatibility in 10.4 for items you may otherwise want iTunes 10 for which requires 10.5 or later be installed. See these links:
http://support.apple.com/kb/dl1056
http://en.wikipedia.org/wiki/ITunes_version_history
You'll need to use the original iMac G5 installer discs to restore your Classic environment, if you find you have to erase or partition a drive, unless you cloned it before. See my FAQ* on cloning, which you should do before installing anything:

Will snow leopard allow macbook to work with airport extreme

I have a macbook with intel core duo (as compared to the newer intel core duo 2) and the airport is 802.11g standard, as compared to the newer 802.11n on the newer macbooks. I just bought an apple airport extreme to serve as a router and this macbook barely gets a signal. Called apple support and they said this macbook not set up for the airport extreme and the downloadable 802.11n enabler update won't load on this machine, which is currently 10.4.11. Anyway, they assured me that if I bought the snow leopard box set and installed it on this macbook it would solve the problem. Will it??

I'm guessing the airport in the computer is malfunctioning.
Not necessarily. Wireless network problems are very tricky to troubleshoot, as they could be caused by all kinds of things. A fridge between you and the router. A neighbor with a router broadcasting on the same channel. A cordless phone. In one very old school building I worked at a couple years ago, any wall or ceiling would drop the signal strength significantly.
The most likely outside source, with such a rapid drop-off, would be a neighbor using a wireless router on the same channel that is interfering with your signal. Try downloading a copy of iStumbler, which will show you all the nearby networks and channels they use.
It is really frustrating that apple support convinced me to buy the snow leopard to solve the problem.
Have you installed SL already and found that it didn't fix the problem? I said that SL will not give you 'n' speeds, but sounds like that's not what you talked to Apple Support about. My experience with SL compared to Leopard on the same computer was that SL found the wireless network faster and never dropped the connection. (Under Leopard, I was having problems with losing the signal sometimes when my wife opened up her Vista laptop in the same room.) So I would advise trying it, just to see if it solves the problem. However, you'll need to be open to the possibility that it won't.

Can I run Snow Leopard on the new iMac

Apple is warrantying me a new iMac because I have had many problems with my current machine. It's a late 2008 Intel Core 2 Duo 2.66 Ghz machine that I have been running Snow Leopard 10.6.8 on. I have a lot of software that runs on Snow Leopard.
They will be replacing it with a new 21.5 inch iMac running Mountain Lion which will be released in the next week or two. My plan was to partition the hard drive, keep part of it for my current Snow Leopard and gradually migrate over to Mountian Lion.
Alas, they have told me that the new machines will not run Snow Leopard at all so partitioning is out of the question but that I can set up a "Virtual Computer" that will allow me to run Snow Leopard within the Mountain Lion Structure. This will allow me to still use my older software in a setup not unlike the Classic system that the early OSX used. The tech told me I would have to get some 3rd party software to do this but was not much more helpful.
Im looking for some specific info on what I need to do to keep my Snow Leopard viable on my new machine while I gradually migrate over to Mountain Lion.
thanks,
Rob

Here is a post that I assembled for a similar question:
Unfortunately you got caught up in the minor miracle of Rosetta. Originally licensed by Apple when it migrated from the PowerPC CPU platform that it had used from the mid-1990's until the Intel CPU platform in 2006, Rosetta allowed Mac users to continue to use their library of PPC software transparently in emulation.
However, Apple's license to continue to use this technology expired with new releases of OS X commencing with Lion (and now Mountain Lion). While educational efforts have been made over the last 6 years, the fact is that Rosetta was SO successful that many users were caught unaware UNTIL they upgraded to Lion or Mountain Lion.
Workarounds:
1. If your Mac will support it, restore OS X Snow Leopar - not available on the newest iMac;
2. If your Mac will support it, partition your hard drive or add an external hard drive and install Snow Leopard into it and use the "dual-boot" method to choose between your PowerPC software or Lion/Mt. Lion - not available on the newest iMac;
3. Upgrade your software to Intel compatible versions, or find alternative software that will open your data files;
3. Install Snow Leopard (with Rosetta) into Parallels:
[click on image to enlarge]
Full Snow Leopard installation instructions here:
http://forums.macrumors.com/showthread.php?t=1365439
NOTE: STEP ONE of the instructions must currently be completed on a Snow Leopard or Lion Mac and the resulting modified Snow Leopard.cdr install file can then be moved over to your Mountain Lion Mac for completion of the remaining steps.
NOTE 2: Computer games with complex, 3D or fast motion graphics make not work well or at all in virtualization.
And according to the author, it's not forbidden by the client EULA. Can't say for sure if the same method will work for Mountain Lion, though. He may have updated it here or on MacRumors, but I'm not aware of an update, or whether one is needed.
I do not give legal advice on MacRumors, I do contend that it is a common Urban Myth that the Snow Leopard EULA forbids its virtualization. Further, in the more than one year that I have been offfering my Snow Leopard into Parallels solution, NO ONE has met my challenge during this period of time to show me one, official written statement by Apple that would support the conclusion that Snow Leopard's EULA forbids its virtualization.
The method does work for Mountain Lion, with the proviso of the NOTE above about currently having to do STEP ONE on a Snow Leopard or Lion Mac.

How do I create a bootable Snow Leopard partition on my iMac running Lion?

Hi.
I have recently bought an iMac running Lion. I also have software such as Office 2004 and CS2 which I believe I can run using Rosetta, however I think I need Snow Leopard for this. If I purchase Snow Leopard from the Online Store, how do I install this 2nd OS within another partition on my iMac (yet to be created) and how do I switch between Snow Leopard and Lion on start up? Will my Lion software and data remain intact as I don't have any Lion disks should I need to reload this? Can anyone help with a step-by-step instructions as I'm not incredibly confident with the repartitioning of my nice new iMac?

To resize the drive do the following:
1. 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.
After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
2. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. (Note: You can only make a partition smaller in order to create new free space.)
4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.
It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss. Your drive must have sufficient contiguous free space for this process to work.
Boot From The Snow Leopard Installer Disc and Install:

Install Snow Leopard on the newly created partition.

Cannot install Snow Leopard on Late 2006 iMac with 10.5.8

I tried already two times to update my iMac (currently on OS X Leopard 10.5.8) to Snow Leopard. The update process runs for about 20 minutes. The iMac restarts, and then there's a message that Snow Leopard cannot be installed. One shall contact the software's manufacturer. I checked in the Installer log file and it says something like it could not u(n)mount a volume.
There are 2 external hard drives connected to the iMac via FireWire (one for TimeMachine). Do I have to disconnect them before installing? There's also a TV tuner (DVB-S) from Terratec connected via USB and EyeTV (a version compatible to Snow Leopard) is installed. I already thought that it is maybe the EyeTV software (that came with the Terratec tuner) that prevents the installer from proceeding ...
As stated, I gave it two tries:
The first time I booted the iMac from an external hard drive with 10.5.8 installed on it, ran disk utility to check, repair permissions and verify the iMac's internal disk (--> everything was fine) and then inserted the Snow Leopard DVD and launched the installer.
The second time I booted the iMac from its internal hard disk (with 10.5.8) (=the disk on which I wanted to install Snow Leopard), inserted the DVD and launched the installer.
No success in both cases.
Any suggestions, help ??
Thanks a lot in advance!
Rainer

I think it will work if you restart from the Snow Leopard installation disc. Insert disc. Restart with the C key held down to force startup from the optical drive. You have already done a +Repair Disk+, which is a smart move before doing any system installation. So when Installer comes up, just proceed with the installation targeting your internal drive.

24 imac snow leopard backup on 27 iMac Lion? Can I restore system from backup?

Hi guys, I have a 24 inch iMac which came with preinstalled Snow Leopard. I am about to buy a new 27 iMac which I beleve comes with preinstalled Lion. I have been using time machine to fully back up my 24 inch iMac. What I want to know, is that when I buy my new 27 inch iMac, will I be able to restore it's system from my Snow leopard 24 inch imac backup? Please get back to me, thank you for your time

Start with Kappy's post here: https://discussions.apple.com/thread/3525616
As it says in the next-to-last paragraph, you can restore some things, but not others.
"Simple" apps, that were just dropped into the Applications folder, can be restored that way, but be careful not to replace any Snow Leopard versions with Lion versions -- they likely won't work.
"Complex" apps must be reinstalled from their original discs. See Transferring Applications for an explanation.
Some Snow Leopard apps won't work with the Lion file/folder structure. Mail is one for sure, and there may be others.
All told, you may be better off fixing whatever's wrong, if possible, and/or getting used to or finding workarounds for changes you don't like.
