How do I uninstall Lion

Hi. I have three questions for you if you don't mind me asking:

1) I have a 3 year old MacBook Pro with the silver keyboard and its main OS at the time was Leopard. Should I downgrade it to Leopard or Snow Leopard?

If it's already got Leopard on it how can you downgrade it to Leopard? And if it has Leopoard on it doesn't that mean if you put Snow Leoard on it you'd be UPgrading it? Are you saying it now has Lion on it? Sorry, the question does not make sense.

2) After using CCC to backup all my stuff, how do I apply it back to my soon-to-be downgraded Mac? Do I apply the backup during Leopard/ Snow Leopard installation or after?

What do you mean "apply it back"? Do you want to clone your copy to your new computer? Or just copy files? If you just want to copy files from the backup, attach the external hard drive the backup is on (you... did... make your backup onto an EXTERNAL drive, right?) to your computer, navigate to the files you want and then drag them into a folder on your computer. They will be copied to your computer.

Thanks.

That depends on what you mean by "apply".... if you're just copying your files from the backup onto the drive of your computer, no there shouldn't be any problems. If you are copying Applications etc. there will probably be problems.

Honestly it would be FAR less work to just use Lion, if that's what you have on your computer now.

Because I could not get a decent answer from this thread, that fit my specific situation (a brand new machine that arrived with Lion on it, but I wanted to back-grade to SL: 27" 3.4Ghz i7 iMac with 4GB RAM), I decided to leave a message here for those of you out there in my position.

I did exactly what was reccomended - I got a set of SL disks directly from Apple (they sent them for no charge because I wanted to downgrade). First I decided to try to put SL on a separate partition, rather than do a wipe and load. After creating the partition, I tried to boot from the disk and got just a gray screen with 3 beeps (no, it is not bad RAM... it worked fine in Lion... keep reading). Then I reboot and set it up to boot in target mode from my 24" iMac running Leopard. I installed SL on the target volume, fine. All went well and I began the setup process before shutting down. I unhooked the two and reboot the new Mac in Lion, fine. I then tried to reboot from the new clean SL install on the other partition: gray screen with the apple on it and 3 beeps, pause, 3 beeps... continuous. Now, the problem was it would no longer boot at all, so I called Apple.

After being kicked up the line a few times (and managing to reboot from Lion after option+command+P+R), I wound up with a tech that told me he had been told by the engineers the new machines being shipped might not work with SL or other previous OSs. They could not guarentee it, but they were not sure. He even told me this was the first time he had run across someone with a new machine who had tried it.

So, here is the lesson: the conditions described for what works to run both, or to back-grade from Lion, in this thread, are fine for older equipment, as in pre-mid-2011. But the advise that has been given "ad nauseum" in this and other threads DOES NOT WORK FOR A NEWLY SHIPPED iMAC with LION PRE-INSTALLED. The hardware will not support SL.

I must now stick with Lion. No choice other than to return the machine.

That's my tale. I hope this actually helps someone.

I'm not clear about what you did.... did you ever completely format the drive in your new iMac and do a completely clean install of SL? Or did you only do an install on a partition?

My guess is that if you mount your new iMac in target disk mode, completely format the drive using Disk Utility and then install SL on it you'll be fine... Don't muck around with partitions or any of that stuff, just 100% format the drive in the new iMac to OS extended Journaled, then install SL on it from the discs.

I did an install on a partition. That is what Apple reccomended.

According to the engineer, my model will not run SL.

I am not about to wipe my hard drive an try a clean install, only to find out it doesn't work. If you want to use your own brand new iMac to try that - post-June 2011 model - fee free. Let me know how that goes for you.

They told me my machine won't run SL; I believe them.

I have lost enough production time on this already, so I'm done. I will keep the machine and hope things improve as updates happen. It is working well enough - I just still have some hinky things like apps that won't shut down and such - not all 3rd party either - sometimes Pages locks up, or Mail. I can live with it, but it isn't the "whoa, that's fast!" machine I was expecting, coming from a 32 bit C2D running Leopard, that's all.

Engineers aren't the final answer, but if they said it won't work that's a strong case.

Why not? Just make a backup of the drive, then wipe it and give it a try. If you make backups you have nothing to lose. Or do a 100% clean install of SL on a non-partitioned external drive and boot from that, same effect.

I had a 2006 iMac that had all sorts of graphics issues, the Apple techs told me over and over that it was NOT a graphics card problem... I knew they were wrong, I installed a new graphics card myself and guess what? Never had another problem. The techs are NOT the final answer, you are.

Why should I? I've had virtually no problems with Lion running Adobe or any other programs on either my new or old iMacs... I continue to believe the problems people are having are not Lion related, they're ADOBE related.... if I have a problem with my software I contact the software vendor, I don't downgrade my entire OS....

Part I: the engineers the tech was talking about were the engineers that helped reconfigure this model. The tech I talked to was the division head of the second tech I was bumped up to. This guy had the ear of the lead engineers. I respect that and their opinion, especially over yours. (Just as FYI, although I am now an artist and graphic designer, my first degree is in EET and I spent nearly 10 years as a field service engineer myself, so I am not totally clueless here.) I do not disagree that they are not necessarily the "final answer" but I believe they have a better grasp than I. I am comfortable with that and do not need to challenge them.

Part II: Why not? Because I would have to dedicate a drive to the project (I don't have a spare and I don't have any disposable income to just go spend another $60 on one), AND it would take time. What part of "I have lost enough production time on this already" did you not understand?

Part III: Good for you. Not my problem.

Part IV: Here's the point - dude, I am not your test bunny. You want the answer as to whether or not the new model has architecture that differs enough to keep it from running SL, do the test yourself. I am satisfied with the answer I got from the engineers that built the **** thing. If that's not good enough for you, too bad.

Addendem: I think you are a troll and I have wasted too much time listening to your argumentative baloney. I am going away now. Have a nice life.

That's fine.

If you've lost so much time on it and are done futzing with it why do you keep posting about it? You obviously want a solution so you keep coming back looking for one, sorry if the one I offered (which would probably work) isn't "good enough" for you or whatever.

I never said it was your problem. My point was simple: Just because the techs say so don't make it so.

I never requested you be my test bunny, I don't need one, everything is working fine on my end. YOU have posted repeatedly and I have offered you options to solve your problem. Honestly I couldn't care less if you solve it or not, I was just trying to offer an option that might work for you, sorry you'd rather complain about it some more instead of doing anything about it.

And in typical "I'm mad so I'm right!" fashion you'd rather call me a troll and storm out than listen to and try out the solution I offered, or debate the point I have made... that the problem is with the 3rd party software, not with Lion, so downgrading and blaming apple is not a viable solution. Must be your artist's temperment or something, why listen to reason and discussion when you can cling to emotions and anger. Have fun with that!

Dude, what, do you work for Apple?

Listen - the name of this thread/discussion is "How do I uninstall Lion?"

And all you have to offer is beating people over the head with "It's not Apple's fault, it's the developer?"

You really have no clue as to why people are here, do you? They want help and possibly a little understanding.

YOU are NOT helping. You're being a jerk.

'Nuff said.

Dude?

Anyhow, if I understand correctly you want to remove Apples product and replace it with an earlier version because Adobes product is out of date?

I think you should.

Kappy, with all respect: if another Mac OS X had been installed on the same volume, I assume GUID partition table could not change. This is a mandatory check only when changing volume destination. Or am I missing something?

I agree. Lion is running on two 2007 MBs and a 2009 MB, all having 4 GB memory, and all fast enough, I do not see any difference between Lion and SL. Slowness, reported by many users, who have upgraded to Lion, has other reasons. I assume that, in most cases, there are old apps incompatible with Lion or other similar situations.

You consider a .1 upgrade to an OS 'jumping off a cliff'?

Kappy, the installer wont load. message says "you cant use SL with this computer"

Options in the disk utility are not available as described in your instructions. Any further insights?

I heard from Apple Genius Bar today that my 2009 MBA with 2 GB of RAM is not suitable to run Lion. I was told that 2 GB is not enough.
