Intel Mac :: Downgrade To Snow Leopard From Lion Possible / Safe?
Mar 30, 2012
I've been reading a lot on the process of downgrading from Lion to Snow Leopard. But it all seems a bit blurry as no actual facts are posted, and I couldn't find out if its only possible for machines that did not come with Lion pre-installed (mine did). I'm really keen on downgrading so I can get back to work. The compatibility with most of the audio plugins I use is not good, so I'd rather just keep working with the previous operating system. I have read a lot of the other threads on this matter, but the main point here is if it is possible to downgrade in a machine that came with Lion preinstalled. I've seen videos on how to do it, but they don't mention if it works on any Mac or only in those that, at some point, already had a version of Snow Leopard installed.

Basically looking for an answer to the title question. If it is possible, which version of Snow Leopard.do I need to buy....the $29 version? I'm basically wanting to downgrade because I want iLife 11 suite which has the iWeb software.

I recently purchased a new MacBook Pro (I bought it in Janurary, so not the new ones). My POS software will not run on Lion. I was wondering if there was any way that I can downgrade my computer to Snow Leopard, I have the disc. Also, I installed Snow Leopard on an external HD but my computer would not start up from that disc, is there any way to fix that? Information: Snow Leopard Version 10.6.3 - Lion Version: 10.7.4 - MacBook Pro 2.4 GHz Intel Core i7, 4GB RAM.

We have a new iMac at work bought through Apple's refurb site. It is running the latest version of Lion with all firmware updates, etc. It is replacing a G5 running Tiger.
The problem is this“ it is supposed to be running Adobe CS5, but also CS4 (and Office would be handly also) We have other macs here, some running Leopard, some Snow Leopard, but the Adobe apps are not happy at all in Lion, and InDesign CS4 crashes all the time and won't even print without jumping through a million hoops (obviously the Office 2004 app won't run at all).
Due to the level of issues we are having with Lion (and the reliability of the all the software under Snow Leopard) I am looking to downgrade to Snow Leopard.I have a full retail version of Snow Leopard (10.6.3), but the Lion system won't boot from the disk, it just gets to the grey screen, and beeps three times. I presume this means that there isn't the required drivers on the disk to run the hardware, or there's a firmware update that doesn't allow installation.
Am i totally stuck with this OS? I was looking to install Snow Leopard on a partiton, but when i run the install disk from the Lion desktop, it reports that I can't run it because 'I have Install Mac OS X 23.1.1.'I would really like to just have Snow Leopard on my iMac, or failing that, Lion on a small partition, and Snow Leopard and all the programs on the larger partition that I would boot from.

I have a 17 inch MacBook Pro (early 2008). I installed Lion back earlier this year so I could use the iBooks application. Big mistake. Since then my wifi connection constantly drops out. I've roamed these forums and tried just about everything suggested. I would now like to go back to the Snow Leopard software I had installed before.
The problem is the last Time Machine update I ran was on Lion (I know *face palm*). If I were to completely erase my hard drive, install the Snow Leopard DVD, then install the Snow Leopard update, would I still be able to use some of the files from my Lion Time Machine back up? My biggest concerns are my music purchases on the iTunes store and Microsoft Word documents....

We will be replacing our G5 computers with new Macs soon (as in finally!). In the mean time I need to work for awhile on my laptop running Snow Leopard. Unfortunately, before moving to a new Mac I will probably have to switch back to one of the G5 Macs for awhile.Â
Is it possible to move a Snow Leopard mail database back to Leopard?Â

I want to downgrade for any reasons, but I'm worried that I won't be able to get all my apps back (I realize I'll probably have to redownload the leopard versions). Anyway, I only have time machine backups from snow leopard, are they compatible with leopard (ie I use the snow leopard time machine backup to restore my personal files in leopard)?I have a bootable dmg image if anything goes wrong, but I don't want to waste time if I do something badly.

I just got a Mac Mini to use as a HTPC. It came with Snow Leopard installed, but I want to switch back to Leopard.I have a Leopard disc(legal, official disc), but I can't get it to install.I tried inserting the disc and installing from the disc. After I select to install I am prompted to restart the computer, but when I do that the computer just keeps re-booting. I waited for five reboots, but when it did not seem to be working I manually turned off the power.I tried to erase the HD with Disk Utility, but it is grayed out and I can't do anything there either.I tried booting from the disc, but I can't do that either.

I have not yet upgraded to Snow Leopard because of all the negative things about it. But I am wondering now, with all the application updates, 10.6.1 and other Apple updates, is it "safe" to upgrade to Snow Leopard. I am really looking forward to all the new features, but am happy with Leopard right now.

The software update popped up with this update to install, along with other stuff. I unchecked the 10.6.4 update, as I have read bad things about it causing bootup problems etc. I am currently running 10.6.3. Is there a safe way to install it?

Restarted macbook in safe mode (i just pressed shift upon startup and logged in) to correct the resolution for my display settings that were affected earlier today when connecting to an overhead projector. The resolution is back to normal, but now everything is delayed. Moving between windows, opening word, opening an email, is all slow and delayed. This computer has never been this slow.

After that I kept doing google searches, and I noticed that when I clicked on link a specific site of an association that is legit, it redirected me to one of those shady pharmacy website. So that was weird.I reset safari,came here, then I got the anti flashback tool, my mac seemed cleared. I got clamxav. I checked www.dns-ok.us. It all seems fine.I don't install things on this machine, I had a new hardrive installed not long ago.Do I have the latest Java, do I need to update? this is the Java version i have -build 1.6.0_31-b04-415-10M3635

Using 10.6.8, Mac Pro Intel Xeon.I installed a third hard-drive the other day, and older one I had left from a previous mac. I had been wiped, but I noticed the computer started up very slowly, so I removed the third hd again. Still the slow startups, so I started up in safe mode, but then Safari and Firefox would not open, they would crash immediately during startup.So I rest the pram, but still the same issue with Safari and Firefox not opening, google chrome works fine thgouh. Here the crash report from Safari?
Process: Safari [376]

Identifier:com.apple.Safari

I'm trying to free up space, and notice that on my hard drive, under "Updates" there are several. Screen shot below. My question is this: can I delete some of them? Would the most recent update be all I need to retain?

I was using Terminal in my MacBook Pro to check if it was infected with the flashback Trojan but all results were negative. After confirming that I was not infected I typed the word "clear" and then the word "exit" before quitting terminal. Is this the appropriate procedure to close the terminal in OSX? Or it is an overkill? Will these commands affect the functionality of the command line in the future?
