i've done some reading online, theres a lot of conflicting info if a 2011 lion mbp can be downgraded to snow leopard. seems that mbp's shipped with lion may not be able to downgrade. let me know the progress....i wouldnt mind downgrading my mbp to snow leopard

you have to know witch macbook pro you have, the only way possible to do mine is with a snow leopard boot disc of 10.6.6 or later, anything else will not work, i will let you know how it goes have to wait for my boy to get back in town to get the disc, i'll keep you posted

this first post might help you out----> discussions.apple.com

I *think* one should be able to clone an existing Snow Leopard installation (10.6.8) from an earlier-model MacBook Pro onto a current-model MacBook Pro. You would then want to re-apply the **COMBO UPDATE** of 10.6.8 to be sure all needed software resources for the newer hardware are added.

If one were to attempt this, it would be very wise to do the Snow Leopard cloning onto a different hard drive than what came with the newer MBP, so correct operation can be tested/verified before. Fortunately, the recent MPB's are all easy to open and change out drives.

i'm going to wait my boy has the 10.6.6 disc, i'll do a instal on his mac to my hard drive via external case

I my max had lion on it.

I then formatted the drive and used carbon copy to copy my older mac with snow 10.6.8 and made it bootable. Took it out the case and put back in my newer macbook pro and bam I was good to go.

Updated and been on it since last year. I was thinking of going to lion but I guess not.

Do you have one of the "Late 2011" model MacBook Pros?

The question here is whether or not Snow Leopard will run on those particular machines (the current models at this time).

Since the current hardware is only a minor "speed bump" of the previous "Early 2011" MacBook Pros that came out before Lion was released (no major hardware/mainboard revisions), my guess is they would run the 10.6.8 version of Snow Leopard...but I've yet to see that verified.

from what i've gathered by googling, 2011 mbp's that came with Lion cant downgrade to Snow Leopard. Some 2011 mpb's came with Snow Leopard, some folks upgraded to Lion and was able to downgrade back to Snow Leopard.

i will let you know buy next week at the latest once i get the SL disc, i will tell you this, i took the hard drive out of my 13 inch macbook pro i or two years old, put it in my new 15 inch that came with lion it booted up & worked fine

Thats interesting, i might have to try doing that too. i have an old hd from my leopard 2008 mbp thats bootable. i should try dropping that into my 2011 mbp. but for sure, i'm tracking this discussion, let me know your findings

one of the main reason i'm interested in downgrading to snow leopard is cuz mpegstreamclip doesnt work well with Lion

i don't think leopard will work, has to be snow leopard

oh ok i see. then yeah, keep us posted

will do ;)

That's the only way I suspect Snow Leopard would work with the still-current "Late 2011" MacBook Pros. I don't think any Snow Leopard installer disc in existence will boot these machines, but as I said before they're really just a minor speed-bump of the "Early 2011" MBP's so I would expect that a transplanted or cloned 10.6.8 install would work fine...as you seem to be confirming here.

I'd definitely advise running the 10.6.8 Combo Update after doing that, just to be certain all relevant drivers are correctly installed. Otherwise certain hardware functions may be "not quite right".

got you ;)

I was having issues like this with just regular serato and lion. Playing video files but not having video SL open. This was before I updated to the newest serato and serato video.

Here is my trouble topic. serato.com

Lion works fine here.

Lion works horrible for me. Same issue as well. Please Serato fix this!!

serato.com

ok so i just did the instal from a 10.6.6 snow leopard disc, all is working fine at the moment i will test with serato video & let you know

Sorry guys, this is just wrong. I'm not going to downgrade to an older operating system because a BRAND NEW plugin released in April 2012 won't work with my OS, that has been available since July 2011. That's absolutely insane. It should just work.

well guess what it's not working with lion for me, it's crashing left & right.....i'm playing videos right now & it's smooth, the same vidz were crashing in lion, perfect in snow leopard

i don't care if the osx is older i need it to work, i want to have piece of mind when i go to a gig, not a newer osx

so far so good with snow leopard, will keep you guys posted ;)

very cool joee. so let me get this right (cuz i'm too lazy to scroll back up and read lol), you installed SL onto a laptop harddrive, then installed that same harddrive into your 2011 mbp?

you need to READ.........lol

















i'm gonna make you scroll down stop being lazy, alright what i did

























lol.......i reformatted the drive put it back in my mac i have the current $1,799 macbook pro, i than used a disc that came with the Originally released February 2011 macbook pro, popped it in my mbp installed the osx & app disc, did all my updates & that's it i have it playing video just fine now, i'll let you know the real test this weekend when i gig

ok very cool, i might try this, i have the SL discs i bought from the mac store a few months back. i guess worse case scenario, i still have my stock lion hd still intact i could just pop back in if this doesnt work for me

it has to be a 10.6.6 disc that came with a mac that had the same specs

ok, i'll check if this is the same one i have. thanks for the headsup. my mbp is a feb 2011 model

crap, just checked, my SL discs are 10.6.3

than you shoud be fine to downgrade to snow leopard, the problem is when you have a new new ma that came with lion, the older one's had snow leopard than stated shipping with lion

-----> discussions.apple.com

Ok, per the article, my 10.6.3 disc wont work....gotta find me a 10.6.6 disc

I can now confirm:

An OS X 10.6.8 install cloned from a "Mid-2010" 17" MacBook Pro will boot a "Late 2011" 17" MacBook Pro and seems to work fine.

Just to be clear, the newer MBP came with 10.7.2 installed. Tested by booting from a Firewire-connected drive.

May I ask how you did this DJ Mark?

Just did a prom last night. 2 hour set up with truss lights and tvs. Decided to look for updates to serato the night before and noticed I was eligible for a serato video update. Output window worked while I was putting together a playlist without my ttm57 hooked up, But guess what didn't work when I was at my gig! Embarrassing wish I never updated. running os x 10.6.8 cant find com.seratovideo.plist.locke file that needs to be deleted.

General Questions
Where is my Serato Video Output Window or Preview Window?
If you are experiencing your output window or output preview window disappearing after upgrading to Serato Video, please follow these instructions to resolve this issue:

PC
1) Close all programs.

2) Open the Start menu.

3) In the search box type "regedit" (minus the quotation marks).

4) Click the regedit.exe icon and the Registry Editor window will now open.

5) Expand the HKEY_CURRENT_USER folder.

6) Expand the Software folder

7) Expand the Serato folder

8) Right click on the SeratoVideo folder, select "rename" and give it a new name (e.g. old_SeratoVideo)

9) Now open Scratch Live and Serato Video, and the output window should have now returned to default settings.

Mac
1) Close all programs.

2) Open Finder and go to the User > Library > Preferences folder.

3) Rename the com.serato.seratovideo.plist file (e.g. to old_com.serato.seratovideo.plist).

Note: On Mac OS X Lion, the User Library is hidden. To access this you will have to hold down the option key and click on "Go" on the Finder toolbar and the Library option will appear in the drop down menu. You will also need to remove the com.serato.seratovideo.plist.lockfile.

4) Now open Scratch Live and Serato Video, and the output window should have now returned to default settings.

Did you find this useful? Yes No

I thought this was fairly self-evident from what I wrote.

If you're asking what cloning software I use, it's SuperDuper. CarbonCopyCloner would work just as well for that purpose.

all is well played vidz this weekend with no problems at all, so lion & serato video DO NOT WORK for me at all crash after crash

now snow leopard & serato video is working perfect, i'm just glad that i was able to downgrade, now i can go back to video dj'ing :)

i'm looking to do the same thing, i just need to order a new harddrive. luckily, swapping the hd's on the new mbps are simple, so i can experiment with this new snow leopard setup and if its sketchy, i can just drop my lion harddrive back in and go to my gig.

My Macbook pro 2.2 quadcore i7 with 8 gigs of ram, 1 gig Radeon 6750 & 256 gig Solid state Hd came with Lion Osx. I had to remove the HD and install it into another macbook pro unibody previous model so i can install Snow Leopard. Once you install the OS, You have to install the updates from online. It will update the drivers for the Macbook pro that was running on Lion. Try updating twice back to back to make sure you get everything.

Cont: Now remove the HD from the Macbook pro and install it into the original Macbook pro. Now you are good to go. I can Mix 720p & 1080p H.264 music videos at the Best Video Output setting.

Just to confirm.. the late 2011 MBP 15 runs fine with SL 10.6.8.

Oh.. and OSX 10.6.8 with external displays run significantly smoother than 10.7.3 for me.

^^^ yes snow leopard runs much smoother than lion for me too

Cool. Just in case anyone missed this other thread: serato.com

I would have been shocked to hear that the 15-inch "Late 2011" model behaved any differently than the 17-inch "Late 2011" with 10.6.8, but good and useful to see that confirmed.

The one "bugaboo" I've found with this hardware (nothing to do with the OS version) is that if you use an adapter bracket for a second hard drive to go instead of the optical, it CANNOT be a SATA-3 drive (6gb/sec). SATA-2 (3gb/sec) drives work fine there. So my SATA-3 OCZ Vertex 3 had to go in the normal hard drive bay and the WD 1tb into the optical bay bracket.

Supposedly OS X 10.7.4 update should be out soon...maybe that will help with the Lion issues. www.appleinsider.com

Just recieved my 15" MacBook. I was told by the represenative initially that it would come with snow leopord, and BAM it came with LION! Just got off the phone with customer service and , NO you cannot downgrade to 10.6.8.
Shipping it back on Monday.

Thanks

i don't know if you guy are reading i have the newest macbook pro the $1,799 one.....i did downgrade to snow leopard and a is working well

As I've written in great detail...your new machine WILL run Snow Leopard, no need to send it back.

serato.com

why would you send it back? firstly video runs perfectly fine on snow lion. and secondly the person you spoke to on the phone is an idiot. of course you can downgrade to snow leopard. all you need is a disc.

Well DJ Nyce thanks for the confirmation. I was told initially that it would come with Snow Leopord and when I started it up it was OS LION . I am not computer savy as some of you here, so with that $1500 dollars for a machine that may have issues with Serato, was be a concern for me.
But with your post guess I will be keeping it. Thanks again.

PS, is Snow LION a mis quote or a hybrid OS?

lol. snow leapard. nah it was a typo. apple has all these damn cat names. what's next ocelot?

DJ Nyce so you running OS Snow Leopord/LION?

Downgrading a new Mac from Lion to Snow Leopard is in certain cases possible (with installation disk) but you will loose any factory warranty on the machine. At least that is what Apple - The Netherlands told me.

Rodger

How do you do it wish just a disc? I tried and it didn't work....even with the disc apple sent me said "would work".

Im hoping Mountain Lion fixes all the graphics and performance issues Lion had!

Hi Vio0633,

Hold the ALT button during startup of your Mac. Insert OSX Snow Leopard disc and wait till its icon appears. Then choose this disk in boot options. You will get the startup screen for MAC OSX Snow Leopard installation.

Load Disk Utility from the menu bar (in top of screen) and format your disk first. Then fresh install Snow Leopard.

Do this AFTER you backed up your disk and files completely! Use "Time Machine" AND a backup tool like "Super Duper" so you are absolutely safe.

Good luck.

Rodger
