Snow Leopard Network Utility versus earlier Network Utility

I have two Macs running 10.6.1. On one of them, when I use Network Utility to check for open ports, it always shows port 21 open on any machine I query. However the other Mac shows port 21 to be closed. I've run Network Utility on Macs running 10.5 and 10.4 and they show port 21 closed as well. I'm querying other Macs on our network which have their firewalls on and are not allowing ftp access. Yet for some reason, Network Utility on this one Mac shows all of them as having port 21 open, whereas if I run Network Utility from other Macs, they all show port 21 as being closed.

It may depend on which subnets the Macs are. Anyway, to be sure from the terminal just type:
telnet <Mac's IP> 21
If the port is closed you get "connection refused", otherwise you may get a prompt. Even better try FTPing those macs.

Cannot install snow leopard in macbook pro early 2011. disk is rejected. what do I do?

Unable to install snow leopard in macbook pro early 2011. When I put in the disk, the computer does not accept it. What can I do?

lord1908,
some Early 2011 MacBook Pros originally came with Snow Leopard installed, and some originally came with Lion installed. If yours originally came with Snow Leopard installed, then you should be able to install Snow Leopard from its model-specific grey Mac OS X Install DVD. (The white retail Snow Leopard DVD can’t be used with it; it was made for use with earlier models, which originally came with either Tiger or Leopard installed.) If yours originally came with Lion installed, then it won’t accept any Snow Leopard DVD; instead, you’d be able to use OS X Internet Recovery to download and install its original version of Lion from Apple’s servers.

Snow Leopard networking conundrum.

I'm new to Snow Leopard but I've been networking my various Macs since System 7, and every upgraded OS has brought its new challenges; this one is no exception. I have my older desktop with two drives (One called Tiger, one called Panther, for obvious reasons), each holding files I want to access from my Snow Leopard MacBook. Shortly after upgrading, I managed this, much as ever before in earlier OSs: Picked the desired drive, logged on as Registered User and so on. At that time the Connect window gave me both drives and User names as options, just as in earlier OSX versions.
But that's suddenly changed; now, whether I Browse for servers (Command-K) or use the Network icon(Shift Command K) all I get as options are the User accounts—badged as if they were removeable volumes—but the drives themselves are not visible. However, the overall computer does show in the Network window, but double clicking it only gives the same User/volumes as the Connect to server… window.
By sitting at the desktop, and opening its Sharing preference pane I discovered that "…other users can connect to your computer at <its name>.local", and sure enough, typing that into the Connect to server window did the trick, revealing the two drives as connection options (along with just one of the seven available Users) Then all I had to do was figure out how to get the drives into the Favorite servers window for the future.
So I solved my problem, but I don't for the life of me understand what's going on, or how it's supposed to work. Nor why it has worked one way before, and another recently. Can any one shed any light?

A bootable clone is a copy of the system disk that if made properly will boot your Mac in the exact same manner as the original system disk. I know of two applications that are capable of making bootable clones. They are CCC or SuperDuper. I use SD.
You need an external drive to point the application at in order for it to make the bootable clone.
In order to test the clone, hold down the option key while booting. This should bring up all of the bootable devices that the Mac finds. Select the devices with the clone and allow the Mac to boot. If it does you can then proceed to the upgrade knowing that anything goes wrong a working system is only a reboot away. I know that always give my warm fuzzy feelings at upgrade time.

Snow Leopard Disk Utility not showing Disk

Heya, before anyone jumps to conclusion that the disk is just dead, please read the following info.
Background: Basically I'm upgrading to Snow Leopard and I had a striped RAID that I wanted to break and format. They held my Leopard install and I know there's issues w/ SL install seeing RAID (even doing disk boot didn't work for me) so I went the route of booting from SL disk and I broke the soft RAID.
_The problem:_ After I broke the RAID only one of the two HDs was showing up, the one in Bay 1. So I formatted it to see if for some reason it would do something about it. No dice. I even tried taking out the other disk and putting it in bay 1, but to no avail.
*So here's the weird part*: I booted with the Leopard disk and it saw both drives with no problem. The other one that wasn't showing up still was thinking it was part of it's own RAID but after I Erased it, it looked exactly the same stat wise as my other Seagate. So key point: _nothing wrong with the HD_.
_Other info:_ I went into the System Profiler on each booted OS disk and the Leopard one was showing both drives in the Serial-ATA section just fine, wheres Snow's Profiler said there was some error finding the info. Believe me I tried this several times, back and forth.
So has anyone had and/or fixed a problem like this where Snow Leopard's disk utility is only finding one (a specific one) hard drive that was perhaps previously raided?

Update : So I talked to Apple Support and they suggested installing Leopard on the one drive that is found and seeing if it recognizes the drive afterward. It did in fact find the drive just as I had named it. *The Bad*: obviously I can't create a soft RAID using the boot drive while actually booted up and of course the SL install disk still won't find the drive.
But there's a new development: I did the sleep wake test to make sure I didn't go through all this trouble for nothing (I was having a wake from sleep problem in Leopard) and after successfully waking it gave me a nice error saying how a drive was ejected improperly *and the drive no longer would show up in the finder* and the system profiler threw up another error.
I did the same sleep wake test booted in Windows 7 on my 3rd bay drive and both drives would show up and be usable (or at least readable) so I'm still pretty sure it's not the drive.
It must be something about OS X not wanting to power-up or read my other drive correctly, especially after sleeping?

Lion to Snow Leopard Networking issue

After upgrading from Snow Leopard to Lion, I can't seem to be able to connect back to my other mac that is running Snow Leopard. When I select it in finder, and enter my credentials in "connect as" it responds with a connection failed. I know the credentials are correct as I log on to the other mac with it. I also tried to connect as Guest but it did not work either.
Sharing is turned on on the other mac, including the printer but I can no longer access it.
Ironically, I can connect to my WIndows XP machine which is on the same home network!
Any advice would be welcome.
Charles D.

OK, this is not "downgrade", this is new installation into new partition. Downgrade would mean that you started Snow Leopard and it reverts everything from Lion to Snow Leopard leaving intact all (or majority) installed applications, settings etc.

Snow Leopard Network Problems

Hi all.
I'm setting up my second Snow Leopard Server machine and I'm having the most frustrating networking problems.
I'm setting up a server with two NICs, and for some bizarre reason connection will NOT work. Trying to ping within the subnet of the inoperative connection produces "no route to host" errors. Switch the IP configurations between the two NICs, and the problem follows the primary configuration. The same network settings work correctly on a different machine, so the problem is definitely software.
I can't help wondering if this is related to source-based routing in 10.6. But I've tried flushing the routing table to no avail.
This exact same issue happened with the other Snow Leopard server I set up. After a few days of idling, the problems magically resolved themselves. Unfortunately, I don't have time for that to happen with this server.
Any suggestions?

The forums are littered with dual-controller subnet routing discussions; it's a very common issue.
Easiest fix: don't use a Mac as an expensive (and slow) IP router (or NAT box). Use an external firewall.
If you really want to wade into IP routing (and do you actually have enough network traffic to warrant lighting up two gigabit Ethernet connections right now?) then poke around for the existing discussions of setting up the ordering of the controllers and establishing subnet routing live and after each reboot.
I'm probably going to end up writing an article and posting it, as this arises way too often, and folks are understandably having issues with locating the problem given that most (understandably) don't know they need to look for subnets and static routes and such.
Existing threads including [this|http://discussions.apple.com/thread.jspa?messageID=10688941] and [this|http://discussions.apple.com/message.jspa?messageID=5697532] are reasonable starting points for your dual-NIC quest.
One other related gremlin that crops up here is the subnet addressing assignments; you'll usually want to have the (co-resident) NICs using addresses in separate subnets or routing can get squirrelly.
Or plug in the external firewall (which has other advantages) and use it as the router and firewall and NAT box for your LAN.

Why cant i install Mac os x snow leopard on my Imac early 2011

I have mac OS x mountain lion and I'm trying to downgrade to snow leopard by making a partition and trying to boot the install dvd that I just got but when I try to boot the install dvd by holding down (c) or doing it in the system preferences > start up disk the apple logo just appears can someone help

There is no Early 2011 iMac. There are Mids and Late. That's it. Mids came with 10.6.6 or 10.6.7. The Late requires 10.7. It's a convoluted process for the Mids, but you can install Snow Leopard on them.
How To Run Snow Leopard On A New Mac
This does not apply to new Mac Minis or MacBook Airs. When newer models are introduced that also require Lion for hardware support, the techniques described below will no longer work with the possible exception of using Parallels 7.
What has to be done:
1. Create a new partition on the hard drive.
2. Get a clone of a 10.6.8 Snow Leopard system. Put the cloned Snow Leopard
        system onto the new partition.
Step One: Create a new partition on the hard drive
To resize the drive and create a new partition 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.
Step Two: Obtain a clone of a Snow Leopard system:
You will need access to a Mac already running Snow Leopard. You will need a 16 GB USB flash drive or an external hard drive to which you can clone the Snow Leopard system from the Mac that has Snow Leopard installed. Alternatives are:
Option One:
Install a new Snow Leopard system onto a USB flash drive. Boot the Mac used for installing with the USB flash drive. Update the flash drive system to 10.6.8 using the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard. Verify that you can boot the Mac with the USB flash drive.
Take the USB flash drive to your new Mac and try booting from it. If it works then clone the system from the flash drive to the newly made partition:
          Clone using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the Destination
      entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the new partition on the internal drive. Source means the USB
flash drive.
Option Two:
If you have a large enough external drive you can erase and use, then it would be easier to just clone the entire Snow Leopard system from the source Mac computer to the external drive.
          Clone using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the Destination
      entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the external drive. Source means the Snow Leopard Mac's
internal drive.
After cloning verify that it will boot the source Mac. If so then take the external drive to your new Mac boot with it. If all is well then restore the clone to the new partition on your new Mac:
          Restore the clone using Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the Destination
      entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the new partition on the internal drive. Source means the external drive.
You will need a retail copy of Snow Leopard. If you need to purchase Snow Leopard contact Customer Service: Contacting Apple for support and service. The price is $29.00 plus tax. You will receive physical media - DVD - by mail.

Is there any way to make a snow leopard partition on an early 2011 MacBook Pro that was upgraded to Lion, without the original boot disk?

So I have an early 2011 MacBook pro, I believe it shipped with snow leopard originally, as I purchased and upgraded to Lion fairly early on. I am trying to make a partition right now and have it run snow leopard so I can use programs that have PowerPC.
I should note, I replaced both the RAM and the harddrive in my Macbook pro. I changed from 4 GB of ram (that came shipped) to 8 GB of ram from a 3rd party, that I installed on my own months ago, have registered in the computer and have been working fine for quite some time now.
Also I should note I replaced my harddrive. I went from what ever the standard 500 GB harddrive that shipped with 15 inch early 2011 MB pro's. I now have a 3rd party SSD that's 240GB's that I also installed on my own, (at the same time as the RAM---Black friday items) The harddrive has been working just fine since then.
In installing the harddrive I borrowed a friends external harddrive and used a program called carbon copy cloner to get everything over to the SSD.
Now here is my issue. I have ordered the Snow Leopard (10.6.3) install disks from apple, I have created a partition on my SSD for snow leopard, but when I try to select the install disc for snow leopard at boot I get three beeps.
I know this issue has been posted elsewere but it said answered and the answer is no longer available. I also am unsure if any of the RAM or Harddrive swapping could have been causing the issue. I have the old harddrive and RAM still, but unfortunatley have no external harddrive anymore or money to afford one.
Is there any way I can install a partition that runs snow leopard on my early 2011 MB pro with what I have (new SSD, New RAM, Current version Lion running, no external drive, lack of original snow leopard disks [I lost them ] and the general 10.6.3 snow leopard boot disks).
Let me know If there is anything I can do. I'm a now broke college student so i'd like to spend as little $$$$ as possible
*PS I should also note the DVD drive is working fine, it reads the disk, the disk is brand new, it plays DVD's fine and has never had any issues in the years i've used it for similar tasks*
sorry for the long drawn out post, I just wanted to include as much as possible from what I've seen other people have issues with

As the last post suggests, call Apple and order a replacement original disc for about $17. They will ask you the model and serial numbers.
Your retail version of Snow Leopard OS 10.6.3 will not work on that Mac as it requires a minimum of OS X 10.6.7 to boot and operate.
Another alternative is to again borrow another Mac to install your retail Snow Leopard into an external HD or partition, upgrade it to 10.6.8 and then clone it back to a partition on your MBP.

I need snow leopard for macbook pro early 2011

broke my disck original. I have Lion but i need return a snow leopar. I have retail snow leopard 10.6.3 but does not work. Reading. I have read que i need snow leopar for macbook pro 13 early 2011 especific

Original install disks may be obtained from Apple. Give them a call and be prepared to give them the serial number of your MBP. There is a charge.
Ciao.

Snow leopard Disk Utility

Hi. I have recently installed Mac OS 10.6 on my Intel iMac (8,1). I am very pleased with it, but for some reason Disk Utility crashes each time I open it. I get an error message saying Disk Utility quit unexpectedly. I relaunch it, but then the same thing happens. At first I thought there was some error, so I restarted. That didn't help. Now disk utility is basically "useless." Is there any Terminal hack or something?

Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk. Maybe it will fix it.
You could have some directory corruption. Let us know what errors Disk Utility reports and if DU was able to repair them.
Then Repair Permissions.

IMac i7 need to install snow leopard NOT Lion - Will it allow the install of 10.6?

I have a bit of a quirk to deal with, a client has a Snow Leopard Network but just recently had a replacement iMac i7 delivered for a previous box from earlier in the year. The IT Contractor is stating that the machine can only take Lion and will not install Snow Leopard. The problem is there is some FileMaker issues that have come up with some deep level custom functions that have exposed a critical problem and the machine needs to run Snow Leopard. This would be until the work around is developed for the software solution or FMI comes out with the next version of FileMaker resolving the issue.
Is the IT Contract full of it ? If not is there a way to force the iMac i7 to accept a Snow Leopard installation ?

For years Macs have not be able to run earlier versions of OS X than they originally shipped with so this is nothing new. It also makes a lot of sense when you think of it, one of the reasons Mac's run so well is the software and hardware are optimized to run well together. Attempting to install an earlier version of OS X than what the machine was designed for is technically possible but it also comes with significant risks because you're then dealing with a system that wasn't designed to run well together...in other words you're emulating the MS Windows world. While there can be some temporary inconvenience as you're experiencing in this case Apple makes these decisions for a reason. While not always obvious to we end users but there are good reasons none the less.

Transfer individual apps from Snow Leopard to clean installed Mountain Lion

I had a Snow Leopard on Macbook Pro Early 2011.
Took a backup (a clone with Carbon Copy Cloner) of the system and erased my volume to install an SSD and HDD combination, then did a fresh install of Mountain Lion from thumb drive , which I had prepared earlier from an App Store download.
Now installing all applications manually to have it clean. Some apps, though, I cannot do clean install, either because I do not have the original install packs or do not want to lose all my personal data on them.
iLife (Garage Band, iDVD, iPhoto, iMovie, iWeb, what else?)
Mail
iTunes
HOw can I go around bringing these apps from my clone into the new ML ?
I am aware of the option to pay for the iLife apps in the App Store.

macjack's suggestion worked for the iLife apps.
I just ignored the "expired certificate" warning of the Disc 2, "Application Installation Disc" and installed the bundle.
Then without opening them, I went for "software update". Now the App Store allowed me to download the updates. Will take several hours. But I think they are the most up to date versions, so I won't have to pay.
for mail, I followed the below instructions found here (http://forums.macrumors.com/showthread.php?t=1422832)
1) Go to users/Library/Containers/com.apple.mail/Data/Library/Mail

Can I repartition my MB 10.5.8 to dualboot Snow Leopard on the same int.HD?

I want to repartition my MacBook HD currently running Leopard and install Snow Leopard in a dual boot system. Is Snow Leopard compatible with my early '08 MB? Are there any steps I need to perform or pay particular attention to? My original Leopard install is corrupted and needs to be reinstalled from scratch.Not sure if I can even create the current firmware install discs I would like to have. I have an extra 100 Gb of space for a Snow Leopard install. Also interested if Mac OSx Server is a possibillity to install. I have the Intel chip. Very intersted in your input. Thanks in advance.

15 is probably enough. And if you kept your home dir in a separate volume then you could use your same home dir on both leopard and snow leopard. This is one of the reasons I recommend keeping the home dir on a separate volume. Very convenient for switching OS's or needing to use a (backup) copy of the current OS.
