Downgrade latest macbook pro late 2009 model from snow leopard to leopard?
hi all,
I have been contemplating investing in a new macbook pro 15 for quite a few weeks so hope someone can give me a clear answer on this.
basically i have a 3ghz mac pro 8 core intel machine with lots of pro apps, logic studio (8) and FCP HD studio 2 etc running on leopard.... these were designed for that os. I do not think that if i bout a macbook pro with snow leopard installed, that these apps would work so is there a way of successfully downgrading from SL to L, i have read that you need to downgrade to atleast L 10.5.6/ 10.5.7 for the mbp to recognise the correct drivers sets etc....is that correct? is it as easy as that?
If i downgrade the most recent mbp model to leopard does anyone know if all the functions will work, trackpad gestures , port etc...I just want to have 2 identical systems at the end of the day one mac pro and one mbp with the same configs so i can take my video/audio out of the studio
I refuse to upgrade to the latest app versions for the sake of an os (which is currently buggy according to most)
my configuration for my mbp would be the 3.06Ghz processor (with the matte screen!) and 500gb 7200 8gb RAM.
Please tell me if someone has done this procedure and had their mbp working fine or any probs encountered if i was to do this!?
I would be buying the mbp brand new with no data so no need for a back up with time machine etc..i just need a clean install of L os.
thanks in advance

There have been several reports here from people who have downgraded mid-2009 MBPs that came with SL installed on them to Leopard. As a general matter Apple discourages this...
http://support.apple.com/kb/HT2186
...and in most cases it is impossible to directly install any older OS on a Mac than the one that was installed on it at the factory, or impossible to boot the computer if one does so by indirect means (e.g., cloning from another computer or an external hard drive). So this seems to be a special case where what is usually impossible can be done successfully, but it is probably true that no earlier version than 10.5.7, build 9J3050, will be usable. That's the build that was installed on all Mid-2009 MBPs in the early days of their production run, before the introduction of Snow Leopard. I don't know whether there is any retail Leopard installer DVD for that version or for 10.5.8; they may be available only on model-specific DVDs.

HI, SO I BOUGHT MOUNTAIN LION ON MY MACBOOK PRO TRYING TO UPGRADE FROM SNOW LEOPARD, AND WHILE TRYING TO REINSTALL THE OS SETUP AS IT SHOWED IT COULDNT BE VERIFIED, I CROSSED OUT MOUNTAIN LION FROM MY PURCHASES, ITS NOW GONE, DO I HAVE TO BUY IT AGAIN?
Please google search for "Mountain Lion disk crash" before upgrading you mac pro. You might need to replace you Mac hard drive after the upgrade.So many people had the same problems including me.
Be aware of the Mountain Lion upgrade problem. -
upgraded my macbook pro to mountain lion from snow leopard does this mean i can upgrade my imac as well for the same price? And will it mess it up?
You can upgrade the iMac for no extra charge - sign into the App Store there, download and install 10.8.
I recommend that you make a backup (Time Machine is probably the easiest method) before you install, and make sure that you are not using any applications that are incomptible with 10.8 (eg Office 2004) - other than that, it should go smoothly.

Macbook pro (late 2009) freezes at desktop screen
Hi,
I have a macbook pro late 2009 model 17 inch, running Lion 10.7.3
every now and then (once per ten boots) I have a specific freezing issue, after booting and loading the desktop screen and icons, mouse cursor is moving but I can't do anything more, the only think that works is a hard reset from the power button. I tried by re-installing Lion but the problem persists. I observed that this is also usually happens when I restarting from Bootcamp (windows) to OS.
Any idea or suggestion?See this article. You might have damaged software, and you'll have to reinstall from the recovery mode, depending on which version of OSX you have.

I recently attempted to re-install Mountain Lion on my MacBook Pro late 2012 model and the internet recovery is failing. I have absolutely no clue what to do here. Any help is greatly appreciated. Thank you.
- Currently if I boot it up there is a flashing folder icon with a question mark in it. I am assuming this means there is no OS because I wiped the SSD and tried to reinstall Mountain Lion
- When I hold Command+R, it prompts me to Choose Network... the problem with this is the wifi constantly is disconnecting. The Retina 2012 does not have an ethernet port so i have considered buying the attachment then returning when done.
Once again Thank you in advance.
Best.There is nothing to do if you don't have a reliable Internet connection unless you have a copy of the Mountain Lion installer application from when you first installed it.
Install or Reinstall Mavericks or Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
OS X Lion- Erase and reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless. -
13" MacBook Pro (Late 2009) - nVidia 8400m stuttering graphics.
Recently, my nVidia 8400M GPU seems to have started acting up on my 13" MacBook Pro (Late 2009). Whenever it is coming under a lot of heavy graphics i.e. games, the FPS rate begins to drop - understandibly, this is normal. However, it's predictability and duration is not.
Both under Mac OS X Snow Leopard and Windows (via Boot Camp) the problem occurs and will occur under any heavy graphics. Currently, the only games I play on my MacBook are Source based (Portal 2, L4D2, Team Fortress 2) and Minecraft; all of which have the issue.
The issue is that once the game begins, the FPS is fine, usually hovering around 24-30fps on full resolution with decent settings which is high enough for fluid gameplay. However, 5-10 minutes into gameplay, the FPS plummets to around 12 fps in a reoccuring pattern (demonstrated as best possible below with '-' being smooth gameplay and and '.' being a 'stutter');
----- . . . ----- . . . ----- . . . ----- . . . ----- (and so on)
It's fairly rapid, the smooth might last for a few seconds, stutter; smooth, stutter, smooth, stutter in a rhymic predictable pattern. At first, I attributed it to possibly a flaw in the Source code for Mac, it's still fairly new. But then Minecraft started. And now it occurs on Windows so it must be a hardware issue.
After maybe 10-15 minutes, it'll resume a normal FPS that's playable (or oddly, if the map is changed or refreshed on TF2, that kick starts normal FPS). Once it's settled down, you could close the game, come back hours later and wouldn't have the issue - if you put the Mac to sleep or shutdown, it'll occur again on next boot.
Is this a common occurrence with the 8400M on MacBooks? I used to play TF2 on Windows via Bootcamp before it was released for Mac and can never remember having this issue.
Is this something that could possibly be resolved instore? My MacBook Pro is still under AppleCare, would it be worth them having a look at it?You say recently.... I suspect that it has something to do with the 10.6.8 you have posted on the bottom left of your specs. I too had this very same problem and it turned out to be some apps that were not yet optimized for 10.6.8 I had to pop the install disk in and downgrade to 10.6.7... problems have disappeared since then. Good luck! Check your activity monitor and see what the CPU usage is when you boot up also check your system memory... After the update my computer the new MBP i7 2.2ghz was using 50% of the cpu at idle didn't notice it until I finally checked activity after having sluggish performance editing in aperture and restarting multiple times.

Macbook Pro (Late 2011 model issue)
I purchased my Macbook pro (late 2011 Model) a couple of months back, towards the end of last year. Staright after i had purchased it, and had got it delivered i experienced cracking and clicking noises coming from within the Hinge of the Macbook. And got it replaced for a brand new one as i was still within the 2 weeks prior to purchase, as the apple policy states i was eligible to get a new if i had any problems. So i did. And the brand new replacement macbook pro that i have NOW has the same problem. Ever since i got the other one replaced THIS ONE has the problem or rather much worse, Cracking and clicking noises everywhere whenever i handle the notebook or carry it there is cracking noises everywhere. Whenever i open and close the screen lid, UP or Down. There is loud clicking noises coming from inside, sounds like something is breaking. This is totally unacceptable. First macbook had issue, replaced it, And now replaced Macbook pro is much worse. Since i had it replaced i havent had time to come bring it in. It still bears the same preoblem and is getting worse!
You're just going to have to take it into your local Apple Store. They won't replace again but you're still within your one-year warranty so they will certainly repair. I have the same model and have not have any of the problems that you describe.

I have a Macbook Pro late 2012 model with intel processor and 4G of RAM. I upgraded to Yosemite and now my system is so slow. I do not have a backup to revert to because of insufficient space. I have ordered a 1T external drive to do a backup now. What can I do to improve my system performance? Do I need to upgrade RAM or do I have to reinstall Mtn Lion?

Macbook pro late 2009 turns on twice and black screen with no booting
my macbook pro late 2009 (10.6.7) when i press the power button it turns on, then it turns off by itself and then on again and gets a black screen and nothing more no booting sound and i just hear the fans or the Hard Drive going... i really need help with this one
Hello aB_Cepeda
For issues with your MacBook Pro not starting up, check out the articles below as they pertain to issues with start up. The big thing to look for to troubleshoot is to see if you can boot to either your Installation Disk or Recovery HD. If you can, try using Disk Utility to verify your hard drive to make sure that there are no issues. You may need to reinstall Mac OS X Snow Leopard.

When my MacBook pro late 2011 wakes from sleep i have it set to make me enter my password, but when that pace comes up the resolution of it is smaller than my screen. Why is this happening?
I was at the Apple Service. The problem was the 750Gb Toshiba HDD. It's incredible what noise can make that little thing
I didn't know the hdd position is on left on MBP 17" , I thought is the same position like MBP15"
I did't lose any kind of data.. it was fix on time.
Anyway, thank u guys....and don't forget that noise !!!
P.S. I'll make a song with that noise sample to remember it -
My MACBOOK Pro turned out to be Snow Leopard, and later upgraded toLION. And update the EFI, I would like to replace the Snow Leopard, EFIcan not boot, how do? How to use the Snow Leopard install disk to reduce EFI?
Do you mean some of your software does not work in Lion? Do you want to return to using Snow Leopard? If so, then do this:
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. -
How do I partition my MacBook Pro so I can keep Snow Leopard and also install Mountain Lion?
How do I partition my MacBook Pro so I can keep Snow Leopard and also install Mountain Lion?
I want to install the latest OS, but I already know that I will lose a lot of my software unless I can partition the hard drive and have two "bootable" drives.
How do I retain everything I have, partition the drive, then reloa the software I own according to which OS it will work under?msmedia wrote:
I do not currently own OS X ML.
I am currently running OS X (10.6.8 Snow Leopard) on my MacBook Pro. It has a 2.8GHz Intel Core 2 Duo Processor. I want to upgrade to Mountain Lion, but many of my software titles will not operate with ML and I cannot afford to replace some of them (Adobe Creative Suite, for e.g.)
After I back-up my HD and then partition the HD, how do I use the back-up to reinstall what I want to the SL partition, and then place the rest on the ML partition.
I have not done what you want to do, so can only offer some general thoughts in support. Take value from the following where you can. No guarantees.
If it was me, I would use a disk clone utility (e.g. Carbon Copy Cloner) to image the existing Snow Leopard disk to an external drive. Then verify that the external drive would boot and run Snow Leopard normally.
I would then purchase and download the Mountain Lion upgrade installer, but not run it. Use Lion Diskmaker to make a bootable USB stick, and perform a clean install of Mountain Lion, replacing the Snow Leopard on your MBP. This way, you make absolutely certain that no third-party drivers or other SL cruft remains to make Mountain Lion unstable. Update to latest ML point release. Fix permissions. Let TimeMachine make a full backup of your ML installation to a different external drive. Then turn of Time Machine.
In Disk Utility, use the + sign at the bottom of the ML partition to add another GUID, HFS+ Journaled partition for Snow Leopard. Resize to taste. Name it differently from your ML partition. Exhale.
Now ideally, you would like to reverse the external clone and put it back into the new SL partition. Then fix permissions. And demonstrate that you can boot into individually stable OS X installations. This would save you alot of work. Resist copying your home directory into ML just yet.
If you cannot successfully achieve the preceding paragraph, you will be faced with a full SL and application reinstall.
The ~/Library contents for SL and ML are sufficiently different that you do not want to mix them. You may want to salvage Safari bookmarks.plist. And, ML created folders in the home directory may have different permissions or ACL settings than in SL. So, my rule of thumb would be to copy folders that you created in SL, and only the contents of matching named OS created folders such as Music, Pictures, Downloads, etc.
For each operating system, you probably want the Time Machine settings to exclude the opposite OS X partition. If you use the same host name in Sharing prefs, then you will mix SL and ML backups on the same Time Machine back up drive. If you use different host names, they will be distinct folders in the Time Machine backups.backupdb and allow discrete restores per host. You may also want to gag Spotlight from indexing the opposite OS X partition. -
I bought my Macbook pro in 2010 and had Snow Leopard which I upgraded when Mountain Lion was available. Now it keeps saying Mavarick is available. Is that another update? Or is that something else?
Mavericks is an upgraded System in the same way that Mountain Lion was, the difference being that it's free. You can download the installer from the Mac App Store (the system requirements are the same as for Mountain Lion so you should be OK there). I've not got it: reports suggest that it is an improvement over Mountain Lion but it has some quirks that may or may not be an issue for you. It has its own forum, so you could look there for information.

I have a macbook pro and the software with snow leopard only has upgraded to 10.5.8, do I need to purchase mountain lion to upgrade to 10.6.8?
Your machine likely can't handle Mountain Lion 10.8 nor 10.7, if it does it will run slow and very higly likely a lot of your third party software and drivers for printers and scanners won't function anymore.
It's because your 10.5 era (or earlier) machine is rather dated, hardware has advanced and is faster, the newer OS X versions have gotten bloated.
I do recommend you call Apple via phone and order the 10.6.3 white retail disks, backup your personal data off the 10.5.8 Mac to a external storage drive and when the disk arrives, stick it in and run the upgrade installer.
Once that's finished, reboot and use Software Update to get to 10.6.8 and stay there. You can buy stuff from AppStore, just don't upgrade to 10.8 (or 10.7) as thats when you'll have issues.
10.6 should run your currrently installed PPC software and hardware drivers. But 10.7/10.8 will not.
10.6 is receiving security and other updates from Apple as more than 50% of OSX users are still on it.

How do I create more room on my MacBook Pro so I can install Snow Leopard?
I've only got 4.something GB left and it says it needs 5 GB?
Which then begs the question, will I be able to do anything with the computer.
I think I need to get some stuff off, but do not know where to look up what is taking up the most room.
I have an extra hard drive.
I have iDisk.
I have a Time Machine, but it backs up one of my three Macs.
Thanks.A utility like GrandPerspective is a good one for seeing what is taking up space on your hard drive.
Video and photo files tend to take up a lot of room.
