Downgrading from Mac OS X 10.9 to Mac OS X 10.8 originally shipped
Hello
I purchased thiis MacBook Pro 13.3 inches online from Amazone Last June.
It was shipped with Mac OS X 10.8.
Being prompted, during 28 October 2013 I wanted to download online Mavericks but failed by corrupting my external drive containing all my backups through the time machine.
Then, on 30 October, a local Apple authorized service provider also failed to restore my data but however restored the system and installed Mavericks Developer Recovery Update after installing Mountain Lion.
Now, I want to go back i.e. downgrad from Mac OS X Mavericks to Mac OS X Mountain Lion 10.8 which was originally shipped to me. I do not know if the builtin Mac OS X is still there in the system.
I shall appreciate if anyone comes forward and help me out.
Thanks.
Try booting using Internet Recovery mode
http://support.apple.com/kb/ht4718
Backup all your data
Make sure your network has WPA security. This does not work with WEP networks
Shutdown your machine
Press the power button and hold Command-Option-R
Wait for Internet Recovery to load a list of networks (read the note at the bottom)
Select your own network
Internet will now download the Mountain Lion recovery image(assuming your mac shipped with it)
Select Disk Utilities
Select your Mac disk
Warning! This is your last chance to back out!!!!
Select the Erase tab
Select Mac OS Extended Journaled and give a name
Exit out
Select Reinstall Mac OS Mountain Lion
Follow the instructions
Viola! You have downgraded to Mountain Lion!
Notes
Sometimes, if the mac already is connected, it will skip the network selection screen
You must erase the disk in order to let the installer continue
Good luck! Tell me how it went

Downgrading from 10.4 to 10.3 on Mac Mini
Does anyone know how to identify which Mac Mini's are not downgradeable to 10.3? I know that if the Boot ROM is 4.8.9 (or below 4.9) it works fine, but is there any way to tell from the serial number or part number without having to open it up and start it? I need to aquire some of the older units, but if it's not opened, I don't know if there's any way to tell.
We are working with the 1.25Mhz versions. It is NOT true
that you can't install 10.3 if the system shipped with 10.4.
We have done this on many systems and it worked just fine.
Well in general you cannot downgrade to a lower version, specifically you may find an example or two. I don't think you are going get too much help in trynig to downgrade the machines that fail to do so. Apple does this so as not to have support calls.
The thing that changed is the Boot ROM when they changed
from >4.8.9 to 4.9.x and then 10.3 would no longer
install.
Basically that's what we've been saying regardless of the cause, you cannot downgrade - in general.
I believe the basic reason why downgrading fails is that as each new mac is release it may have some of its hardware changed/upgraded or added. Instead of trying to patch an older version of the OSX, Apple decided to make life easier. They just release an update OSX and not allow the user to downgrade because it may cause problems and/or increase support calls.

Upgrade Safari 1.2 to 1.3.1 after downgrade from Tiger to Panther
I wished to restore performance to my G3 iBook by downgrading from Tiger to Panther, and have been successful with that and have restored all apps to Panther versions except for Safari. The downgrade (archive and install) left Safari 2.0 on my HD for some reason, which of course wouldn't launch under 10.3.9. I dragged Safari 2 to the trash, downloaded Safari 1.2 which installed fine. However when I try to upgrade now to 1.3.1, I am told by the installer that the software cannot be used with the disc volume (the system volume) I choose to install to.
(BTW, invoking Software Update says my software is all up to date, even though I'm only on Safari 1.2.)
I've seen the other threads which have suggested removing Safari pkg receipts from /library/receipts, but this hasn't helped me in this case; I can't find any thread that had a successful resolution yet. Anything else anyone can suggest? Many thanks.

Welcome to Apple Discussions.
You can try using Pacifist to extract Safari from your install disk and install it. You may then be able to upgrade it more easily, although I can't promise that for sure.
Unless you are absolutely wedded to Safari, I find Camino to be at least as good (I think better) as Safari, and looks almost identical, so that there should not be much of a learning curve. I also use Firefox and especially like it for the measure of security it provides.
Please do not hesitate to post back with further questions or comments.
Good luck.

How to downgrad from mac OS 10.9 to 10.8?
Hi All,
I have macbook pro 15 Early 2011. I have updated my macbook pro with Mac OS 10.9(Mavericks). After fewdays my macbook become terribly slow. So i decied to downgrade from MAC OS 10.9(Mavericks) to MAC OS 10.8(Mountain Lion).
Please provide me the steps to be followed to the downgrade.
I have downloaded my copy of mountain lion and trying to install but it doesn't allow me to downgrade since my macbook has latest OS.
Please help on this.
Regards
BhasinBhasin,
to downgrade from Mavericks to Mountain Lion, you’ll need to boot into Recovery mode, run Disk Utility there, and completely erase your internal disk. Since you have an Early 2011 model, it originally came either with Snow Leopard (and two grey installation DVDs in the box) or Lion (and no installation DVDs in the box) installed. If it originally came with Snow Leopard, you’ll need to reïnstall Snow Leopard from its grey Mac OS X Install DVD. If it originally came with Lion, you’ll need to perform an OS X Internet Recovery to redownload Lion from Apple’s servers and reïnstall it. Once either Snow Leopard or Lion is installed, run Software Update; once the OS has been updated, you can then upgrade to Mountain Lion. -

How do I downgrade from Mac OS X Lion 10.7.5 for my wife , me and my office
how do I downgrade from Mac OS X Lion 10.7.5 for my wife , me and my office
You cannot downgrade a machine that shipped with 10.7 installed. Such a machine can only run 10.7 or later. As for the older machines, you would need to use the old Mac OS X install disks to erase the hard drive and reinstall the system.
I don't really understand the issue regarding minimizing windows. If the difficulty is that you want to use the green "+" button in the iTunes window's title bar to resize the window rather than toggling between the full window and the simplified window with only play controls, that is not unique to Lion. That has behaved the same way for some time. Try option-clicking on the "+" button. -

Hi, I want to downgrade from OSX LEOPARD to OSX TIGER but I have a few questions regarding this. My iMac is originally from Sep 2007 it came preloaded with tiger. I have original install (2) tiger discs version 10.4.10. I want to know if it is safe and what are the necessary steps to do so. Also by downgrading im wondering if a lot of apps nowadays support tiger for example I have photoshop version 5 and 4 these are very important to me. One last question does anyone know of any reliable virus protection for mac that doesnt slow down your computer? because I have read that a lot of them do so. If anyone can help me I would greatly appreciate it! Here are the specs for my iMac

800 MHzMost of the time a perception of general slow performance is the result of installing third party junk alleged to speed up, "clean" or "optimize" your Mac, or to look for viruses that don't exist. Ideally you would know what you installed so you can uninstall it, but if you don't know or aren't sure there are techniques such as Safe Mode and creating a temporary user account to confirm that suspicion.
If you open Activity Monitor it may show a process, or processes, that occupy a lot of your system's time.
Slowness confined solely to web browser activity is often the result of an inexorable progress toward websites that demand ever more processor-intensive tasks. If your slow performance is strictly limited to web browsing, you might try disabling Flash by either uninstalling it, or use utilities such as ClickToFlash that allow you to control what Flash content gets loaded. Flash in itself is not inherently evil, but there is nothing to stop websites or the advertisers who pay for them from writing horrible Flash code that can do everything from hogging 100% of your CPU's time to causing random crashes. You can watch Activity Monitor as in the above to correlate these troublesome web pages with performance degradation.
You are correct; if your computer shipped with Tiger you may certainly revert to it. I forgot that Tiger was shipping on new Macs as recently as five years ago. To downgrade it would be necessary to completely erase your hard disk and boot with the Tiger installation DVD, followed by installing it anew. Such drastic measures are not necessary and you are unlikely to be satisfied with the results anyway.
Assuming your system is free of third party parasitic junk attached to OS X in an ill-conceived attempt to improve upon it, that your hard disk drive is sound and the boot volume has enough free space to work with, by far the best performance-enhancing improvement would be to add more memory. Buy as much as your computer can use and that you can afford. 2 GB is not that much any more.

How can I downgrade from Lion to Snow Leopard?
Hello.
Yesterday, I upgraded my Mac to Mac OS X (10.7 Lion) from 10.6.8 Snow Leopard. However, I wish to downgrade.
Obviously, I would like to not lose any data at all. However, I have never downgraded before.
I still have the Snow Leopard installation disk that came with my Mac.
How should I do this? I was thinking it would be easiest to simply head on over to an Apple Store...
I did some research (aka Googling), and I read up on the subject quite a bit.
If I simply put in the disk, will I be able to downgrade from Lion to Snow Leopard as easily as the upgrade was?
Also, I have heard about holding down the "C" button to do this... how exactly?
I have never backed up my Mac, nor used Time Machine.
Also, is it possible to install Snow Leopard on a separate disk, and set it up so that I can switch between them on command?
Will all of my preferences be saved, or does this wipe everything, not just the system and libraries folders?
I realize that I have a lot of questions, and therefore I appreciate everyone's help in advance. Thanks again.
Sincerely, ZachBackup your files.
Booting From An OS X Installer Disc
1. Insert Snow Leopard Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple logo appears.
5. Wait for installer to finish loading.
Erase Drive
1. Boot from your OS X 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. Upon completion quit DU and return to installer. Install Snow Leopard. Restore your files after the installation has completed. -
Password issue when re-instaling Leopard (downgrade from Lion)
Hi there!
I'm havig a problem:
I need to downgrade from Lion to Leopard, because some of the programs i use, dont work on Lion!
But im havig a problem, after Leopard instalation (and after i erased Lion)... the instalation of Leopard runs with success, but when i have to put user name and password to LOG IN... my password doesnt work! And im sure i only have this password! HELP! Any ideas on how i could reset it some how?
Without this correct password, i need to restore (from my MAC OX 10.7 backup) my MAC to Lion again, because i just cant LOG IN!!
I've made the whole process 3 times already!!
Hope i've explained myself ok.
Thanks for your help in advance... and sorry about my english!
BennyWell, you cannot do a clean install of Snow Leopard without going through the Setup Assistant. There is an automatic suggestion for the username - typically your first name - and a blank password field you must fill in then confirm by entering a second time. If you did not do that then you have no password. Although this will not impede the ability to log in you cannot change a blank password and you cannot install software with a blank password.
So you will need to try this:
How to change your username and/or password from the Terminal
1. Boot into single-user or verbose mode
2. At the prompt enter the following commands. Press RETURN after each:
fsck -fy
mount -uw /
launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist
dscl . -passwd /Users/username password
Replace username with the targeted user and password with the desired password.
reboot
This allows you to reset the password in single user mode without booting from the install media. The above tip is attributed to Satcomer. -

How can i downgrade from os x 10.9 to 10.7 without time machine
can i downgrade from os x 10.9 dirrectly to 10.7?
You should start a new topic thread, so as to get more exposure
to your question; this is suggested due to the status of where you
posted your item (now answered) will see fewer people with any
answer; mostly those seeking answers like their own question.
If your MacBook Pro shipped with a system later than the
DVD version OS X 10.6 you have, the disc would not work.
However, if the DVD you have is the Original OS X version
the MacBook Pro came with, you could use it in much the
same way as it worked before installing Mavericks 10.9.x
By 'reverting' to Snow Leopard 10.6.8 you will essentially lose all
of the content on the hard disk drive. I am not certain if you could
even import anything from a 'time machine' device that had been
created under the newer Mavericks 10.9 system. Since you have
to boot the computer with the install DVD for 10.6, and erase the
hard disk drive, reformat it to GUID and HFS+ (whatever default
for Snow Leopard) and that would remove the Recovery partition
on the computer's hard disk drive, and any other partitions.
Insert the Snow Leopard DVD into the optical drive, and restart
while holding the C key down, until the Installer disc is running
the computer; this would be rather slow, as it reads from the DVD
in order to build the Installer desktop, and access files to attempt
an installation. It may also be testing the hard disk drive, etc.
Once the computer is booted from the SL 10.6 install DVD, you
can look into the Utilities menu (in top of screen, like in Finder
desktop) to choose Disk Utility from the drop-down menu, and
once you launch Disk Utility, note there are sections within it
to choose from. You can choose Secure Erase (single pass) if
you want to have the utility overwrite zeros on the entire HDD.
This a bit longer then a basic erase & install. It wipes everything.
If not, choose to erase all Partitions and be sure it does this.
Afterward you would need to be sure it reformats the hard drive
with a correct partition map & file type. GUID & HFS+ journaled.
The tools are in the Disk Utilty that you run prior to the Installer
itself, as there are options in the menu just like Finder desktop.
Once the hard drive is erased, partition mapped, & reformatted,
it should be easy to put an all-new system 10.6 on the hard drive.
(That is, if the OS X DVD you have is a retail version, and if your
computer shipped with a system older than the one on that DVD.)
Should you choose to, an idea some suggest prior to upgrade
and also prior to downgrade, is to make a full clone of the system
that is running the computer on an externally enclosed hard disk
drive (see carbon copy cloner, or superduper, clone utilities) so
as to have a complete running system that can boot the Mac...
If you had one of these prior to upgrading to Mavericks, it would
be able to run your computer without re-installing. You could just
use the clone utility, again, to clone it back to the wiped Mac HD.
Or run Snow Leopard from the external, at a slightly slower rate
given the USB 2.0/3.0 to an external is slower than bus speed.
Not sure if this helps. However you may benefit from more
exposure to your question in a new topic thread, and that
could be in Snow Leopard, Mavericks, or this ASC section.
There are advantages to posting in an OS X named topic
since people with all kinds of supported Mac would see it.
Hopefully you can revert, and also have some kind of a way
to make a backup of any works you may need a copy of.
The applications in Snow Leopard, older than Mavericks,
may not like to handle files made with newer software.
Though there is a cost to set up the ability to make and use
full bootable system clones, the external drive, time, learning
and testing the idea to see if you can master it before erasure,
the results are worth the effort; since you then have a backup.
A full backup, and it is a manual effort to make this kind, unlike
the 'time machine' bits and pieces, this can bring back the Mac;
if used with a time machine backup, too, could be opportune.
Good luck & happy computing!
