    Can I downgrade a Macbook 7.1 to Snow Leopard?

    This is really annoying, a full class of Mac Mini's come with Snow Leopard, the teacher MacBook came with Lion. I've tried to stick with it, despite it not staying connected to the domain and being unable to bootcamp into XP, but we've now received Logic Express 9 which isn't compatible with Lion, so I've had enough.

    I know the usual reply is 'no' when downgrading a Mac, but the fact that this model MacBook originally shipped with Snow Leopard should mean the hardware is still compatible, yes? So if I installed Snow Leopard onto a firewire disk on my older Macbook, updated to 10.6.8, then took an image and put that on the newer MacBook, that should work shouldn't it (despite not being officially supported I'm sure)

    And yes, I realise if this does work I'll need to buy a copy of Snow Leopard for it, but I want to make sure it works before I do that

    Format the machine and reinstall with the disk that came with the Mac Mini. Job done

    Fairly sure that doesn't work - it won't install from discs that arn't from the same family as far as I can remember

    Just realised my method won't work either, this Macbook doesn't have any firewire ports. FFS

    Ah, looks like there are workarounds for Logic anyway. Probably should have checked before I posted. Still annoyed we're stuck with Lion on this though, it's the same as when Leopard and Snow Leopard first came out, guaranteed issues with binding to the domain. SL is lovely and stable now though

    What is the model number of the Mac mini's? Also, have you installed the latest updates for Logic Express? 9.1.4 is required to run Logic Express on Lion.

    Here's the link to the 9.1.5 update if you need it: support.apple.com/kb/DL1015.

    I had a very similar problem with our two new imacs. Too many problems with AD and an old mac server. Our support company seems to think downgrading was ok.

    I installed 10.6 (snow leopard retail edition) on a virtualbox pc on my imac, updated it to 10.6.8, then used carbon copy cloner to clone to a sparse image file. This was then copied to the c$ share on my main pc. On the new macs, I repartitioned the HD with the disk utility so we didn't lose 10.7 completely (no install disks for it, just a recovery partition). Then connected to the c$ share, install CCC and clone it back to the new partition. Finally, change the startup disk in the appropriate preference pane, and copy the various iLife apps (Garageband, iMovie, iPhoto) to the new disk, and run each one so it re-downloads all the content and libraries etc. After that, just set it up as normal...

    Time will tell how well it works as they've just gone out to our media department today.

    ...or just open up Disk Utility after you have booted from the Snow Leopard disc and format the HDD.

    There's no need to keep the Recovery Partition around if you make your own Lion install DVD or USB flash drive.

    I have the newly released macbook pros (Thunderbolt) which should have come with lion (free upgrade) which had snow leopard on so it can take them. You could use deploy studio to image the mac mini (fully patched) and then deploy to the Macbook.

    I've seen similar guides to those, but they all assume that you upgraded to lion from the app store. Our macs were pre-installed, and I couldn't find the dmgs they talks about. By this point, I had spent far to long messing around with these macs, and had lots more important stuff to do.

    Thanks, I'll give it a try with our Mac mini SL image from DeployStudio over half term then. As long as I can either create a recovery disk or keep the recovery partition in case it all goes wrong!

    I always thought that trying to put an image created on an imac onto a macbook would cause problems, and vice versa, but I guess not then?

    Can anyone tell me how you use an install DVD from one model on another model? I've tried macmini, imac, and a different model macbook pro on my macbook pro and all of them said "please use the install media which came with your mac"
