Lion (non-Snow) Leopard Work-Around Question.

I have a four year old Black MacBook running Snow Leopard 10.6.3 and a Two Year Old MacBook Air running Leopard 10.5.2. I can't find my Snow Leopard install disk. If I download Lion to my Black MacBook, can I transfer the install package via Bluetooth to my MB Air? If not, is there some other strategy I can employ?

Only if you frist update to 10.6.7 or later, so you can DL the installer. BTW, you can get a replacement install disc from AppleCare, providing you have the receipt. I've not tried to install Lion on top of Leopard, so don't know if that'll work, so all you can do is try it. Ensure that you have bootable backups/clones of your current installations before embarking on this venture.

Canon IR-C3100N Snow Leopard work around

I just got this printer.
Installed PPD v2.85, setup using LDP, select print from Mac and nothing come out from printer.
UFR II not working on this model.
Finally got it to work by installing older iR-PS v1.8.1 Canon PS driver meant for 10.5. Will not work from setup, need to tweak as below:
1) Install PPD v2.85
2) Install iR-PS v1.8.1
3) Add printer by selecting 'more printers' - Canon IP (PS) mode.
4) Enter printer's IP.
5) The setup will auto select 'Canon iR C3100 Canon PS' as PPD.
6) Change the PPD to 'Canon iR C3100' from v2.85 PPD.
Wahla it works! If you don't change the PPD, the print queue will say driver error, please reinstall driver.

Sounds like you went to a lot of trouble for nothing. By selecting the PPD, you have bypassed the Canon PS driver, so the process of adding the PS driver would be a wasted step.
While this may have worked for you, for the sake of anyone else reading this post, there is no need to add the Canon PS driver. The transport modules do not work on Snow Leopard and as you have said, if you left the Print Using set to the iR C3100 CanonPS, then you get an error. And by selecting More Printers > Canon IP (PS), you have basically selected IP > LPD as a protocol.
So, if the iR C3100 supports PostScript, then you select IP > LPD for the protocol, enter the IP address of the Canon, enter a queue name of LP and select the Canon iR C3100 in the Print Using menu.

I upgraded to mountain lion from snow leopard, now my photo studio software is no longer supported by powerpc. Does anyone know of a fix so my photostudio will work?

I upgraded to mountain lion from snow leopard, but now some of my applications do not work, most specifically I would like to use my photo studio, but now it tells me that powerpc is no longer supported. Does anyone have any fixes to this problem? I would really like to continue to use software that I already have! Thank you for your help!

PPC software will not work in Mountain Lion because there is no longer any Rosetta emulator. You will only be able to run your older software by creating another partition on your hard drive on which you can install Snow Leopard. It need not be a large partition since you can still keep your files and programs on the main partition. You could also install Snow Leopard on an external drive from which to boot the computer.
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.
After you create the new partition boot the computer from your Snow Leopard DVD and install Snow Leopard onto the new partition.

Ok 1st one. The warning restriction message relates to this line in main.cf:
smtpd_helo_restrictions = permit_sasl_authenticated permit_mynetworks check_helo_access hash:/etc/postfix/helo_access reject_non_fqdn_hostname reject_invalid_hostname permit reject_invalid_helo_hostname
The last reject occurs after the single word "permit" and is ignored.
However, that's not the problem.
I'm not exactly sure what's happening, but this might be a clue.
It would appear that either postfix is not being able to create the socket for private/policy or it's somehow created with the wrong permissions. You might need to ramp up the debug level to get a better idea.
You could check if it's being created by "netstat -a | grep private/policy" in terminal.
My guess is that it's not being created because there is no setup statement in your master.cf file, but I don't understand why postfix would be looking for it if it isn't set up. Private/policy I think relates to grey listing. Maybe gives you a hint.

Lion or Snow Leopard - that is the question

We have an Imac that is just over a year old. We are trying to decide whether to switch to Lion from Snow Leopard.
We have an ipod, ipad and we just got two new iphone 4s. I think my main reason for switching will be to use the new features of the iphone 4s. I have not seen too much positively written about the lion os.
Does anyone know where i can go to see reviews on lion othere than these forums?

Here's a start for you:
http://arstechnica.com/apple/reviews/2011/07/mac-os-x-10-7.ars
To get more, just type "os x lion reviews" in google and get all you want.
I didn't bother with reviews myself. I just made a clone of my Snow Leopard startup disk and went ahead and purchased and installed Lion just after it came out. To me, the best review is how the OS works for me, not what others say about it. By cloning my main drive and going ahead with the installation, I can safely try it out for myself. I've been using it for quite some time now and personally I do like most of the new features. There are some that I don't use but that's the case with all OSs I've had for the last 25 years on Macs.
So my advice is give it a try after you've backed up your stuff. $30 is not much to risk if you don't like it compared to what the earlier systems have cost. BTW, reading these forums is very useful but remember you are reading mostly posts from people who have had problems. The majority of users probably don't have these problems. And DO notice that the loudest protests are coming from those that have NOT taken the precaution to back up their SL stuff first. Not very wise.

Best way to migrate applications from Lion to Snow Leopard?

Hello! own a mid 2011 MacBook Pro and upgraded to Lion back when it came out. I've now realized that Lion and CIFS network drives don't get along well. I want to downgrade back to Snow Leopard. I didn't have any Time machine back ups or anything like that so I believe I have to do a fresh install, this shoudln't be a problem as I have a 6 TB FreeNAS box to back everything up to. My question is about software. Most of the software I have on my computer is free, but some of it, namely the Adobe Design Suite Standard, Quickbooks, and a few other photo/business related pieces of software have been purchased. Is there any easy way of reinstalling them? I guess what I'm asking is, how can I back up my software? Maybe a better question is how do I uninstall software in such a way so that when I reinstall it later it won't give me an error saying the serial number has already been used.

Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard 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. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.
You will need to reinstall your third-party software.

Can I have both Lion and Snow Leopard on One Hard Drive?

My problem is I need to run a PowerPC game on Lion which Lion no longer supports. So i thought i could download Snow Leopard back to my Mac and partiition my hard drive in the process as that is the only way i know of to have both Lion and Snow Leopard. I went through the Boot Camp Asistant process and it seems it will only partition Windows 7 to my Mac when i need Snow Leopard. If anyone has any idea how to help me have both Lion and Snow Leopard at the same time on just one hard drive or figure out how to run the PowerPC programs on my Mac (if there is a way around it). The help will be well appreciated!

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:
Create a new partition on the hard drive.
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
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 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
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 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
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 new partition on the internal drive. Source means the external drive.
If the above seems too daunting then you might consider running Snow Leopard inside an emulator such as Parallels 7. You are permitted to install a single copy of Snow Leopard inside a virtual machine. You will need to first purchase a copy of Parallels 7 and install it on your new Mac. Create a new virtual machine configured for Mac OS X. You may then install Snow Leopard in the virtual machine then download Mac OS X 10.6.8 Update Combo v1.1 and update to 10.6.8. Be sure to include Rosetta in your initial Snow Leopard installation. Rosetta is not installed by default rather it's an optional install.

How do I switch from Mountain Lion to Snow Leopard? New used computer that I don't have anything on yet but has Mountain Lion installed.

I just puchased a used 2008 MacPro 2.8 ghz 8 core and it has Mountain Lion installed on it. I want to go back to Snow Leopard because it is a better stable OS for using Final Cut Pro 7. I just bought the Snow Leopard Discs to install. I need to erase the hard drive and install Snow Leopard. Any help on how
to do this? Thank you.

I have just installed Mountain Lion over Snow Leopard, I now can't open Photoshop?

Hi everyone, I have just installed Mountain Lion over Snow Leopard. The installation went smooth and woks well. Now I find that Ican't open either Photoshop CS or Microsoft Word. I upgraded in order to install Lightroom 5, obviously there is now an incompatability, is there a work around?

If that is the original Photoshop CS, and Word 2004 or earlier, then they won't open because Lion and Mountain Lion do not support PowerPC apps. They must be Intel code. Snow Leopard could run them because it included Rosetta, a PowerPC to Intel (and back) interpreter.
You have a few options.
1) Go back to Snow Leopard.
2) Update your apps to compatible versions.
3) If you have Mountain Lion because newer apps require it then:
a) Install Snow Leopard Server (currently being sold by Apple for $20) in a VM such as Parallels, and then run your PPC apps in the VM.
b) Install Snow Leopard on a separate partition and boot to that version of OS X when you need to use those older apps.

Color Balance Lion vs Snow Leopard

I'm working with QuarkXpress, previously under SnowLeopard, now under Lion. Previously, when exporting a page into a PDF file, colors renamed true. Suddenly, under Lion, colors all emerge pale and uninspiring. I've tried all the display color options in Preferences, but nothing changes. My PDF images consistently emerge in a manner that I cannot send them to my commercial printer. How do I get my true colors back? The only change has been upgrade to Lion. Very frustrating.

No matter what you do, whether you switch OS's or not, always have a backup, preferably two.
Asking which is better, lion or snow leopard is a loaded question. Almost like religion.
Personally I think Lion is a dumbed down version of OSX attempting to merge the ipad with OSX. As you also discovered no Rosetta (ppc support). Obviously you can tell I'm pro-snow leopard.
Let the (religious) war begin...

Downgrade Mountain Lion to Snow Leopard (Keep all data?)

Downgrade Lion to Leopard and upgrade Leopard Lion without Snow Leopard CD

Hey guys,
Can I upgrade from Leopard to Lion without the Snow Leopard CD? I lost it.. And I want Lion or Snow Leopard back due to an image on my Time Capsule that Leopard doens't see.
I ran under Lion but wasn't happy with some of the features. I decided that I wanted to downgrade to either Leopard or Snow Leopard.
I made a back up on my Time Capsule. After it said Last back up 1 min ago I inserted my original CD (Leopard) since I couldn't find the Snow Leopard CD. I completed the reinstallation of MAC OS X and it ran super smoothly. Now Leopard didn't recognize my image (ofcourse since it was Lion) and all the work was done for nothing..
Now I really want to get back on Snow Leopard or Lion so I can reinstate my image and thus all programs and files that I now miss...
Problem: I don't have the Snow Leopard CD..... I can't download Snow Leopard and I can't download Lion because I don't have Snow Leopard... But I paid for both and I don't really want to buy both again just because I made a tiny mistake.
Any of you guys know how I can fix this??
I am now running version MAC OS X 10.5.8 and I'm getting a little annoyed! Lion was AWESOME compared to this version
Cheers!!

I would assume the above may work to downgrade to Leopard by using the Leopard DVD instead of the Snow Leopard one.
If you purchased Snow Leopard then you should have the DVD. If not, then you might call AppleCare about a replacement or simply repurchase it.

Lion To Snow Leopard file recovery

So I had upgraded to OSX Lion a few months ago, and right after I "upgraded" I experienced problems with the internet at my college. I dealt with it for a while but when I became fed up I went to the apple store and said that I wanted to downgrade to snow leopard. i bought an external harddrive and backed up my computer to it. the next day i went back and had them reset my computer to the original settings, and they told me that when i got home i could plug in my backup drive and everything would transfer. I plugged it in and it said that I could not transfer my files because they were from a computer running a newer version of mac os and i would have to upgrade to use them. I obviously don't want to do this, because the newer os was the problem in the first place. So my question is: Is it possible to transfer all of my files from my backup drive while keeping snow leopard running, and if so, how?

Install Lion over Snow Leopard on third party SSD.

I am currently running Snow Leopard 10.6.8 on a third party SSD (Intel 510 series), and am using Trim Enabler 1.2. Everything is running well.
Regarding installing Lion 10.7.2 on the same SSD drive, I have some questions: Should I simply install Lion over Snow Leopard, then either switch to Trim Enabler 2.0 beta 4, or use Grant Pannell's tips here http://digitaldj.net/2011/07/21/trim-enabler-for-lion/. I have read in places that it is best to perform a wipe or some type of reconditioning of an SSD before installing Lion on it. Thanks for any advice you all may have.

I would do the following:
1) buy an external disk enclosure with USB and/or FireWire interface
http://www.newegg.com/Product/Product.aspx?Item=N82E16817146604
2) buy a cheap traditional hard disk at least the same size as the SSD or larger
3) Clone the SSD to the external hard disk inside the enclosure
4) Download Lion from the App Store and copy the installer to a USB Flash Drive
4) Delete the partitions on the SSD (don't bother formatting)
5) Install Lion cleanly with a boot USB Flash Drive
6) Connect the external disk and use the Migration Assistant to move your data back
7) Once you are sure all is good (take a few weeks to be sure) then you can format the external disk and use it as a Time Machine drive. Or use it for other purposes.
Give it time to index everything with Spotlight.
That would be the most clean way to upgrade. Some have been lucky with Lion upgrades but if you have a ton of legacy stuff installed as well as custom tweaks, etc. Then you are likely to run into issues. Best to start clean and neat and migrate your data over. I would even re-install the Apps individually.
Make sure you are not running any PowerPC Apps which rely on Rosetta because that won't work in Lion after the upgrade.
