Dual boot, Mountain Lion and Mavericks and Migration Assistant

Hi all,
I have a Macbook Pro Retina which cam with Mountain Lion installed, and I want to upgrade to Mavericks. However, I have a need to run some apps in Mountain Lion, as official support for those apps will not go past 10.8.5 (Avid's Pro Tools 10) and I need to be able to open archived projects.
I also wish to clean install both operating systems fresh, and do a stripped ML partition, with bare bones essentials, on the smallest partion possible. Mavericks will be the main system, and ML won't host user data, only the legacy apps. I am fine with erasing my 500GB SSD.
My current process is to install ML from the recovery partition, and use disk utility to partition before I do, then install Mavericks from a bootable USB (already made).
So my questions are these:
For ML:
1. What size partition is the minimum necessary to install ML, plus the apps and run without hitch? The legacy apps will take maybe 4GB.I want this as small as possible.
2. When I do a fresh install of ML, what apps can safely be deleted without affecting the system?
For Mavericks:
When migrating my old user account to Mavericks, I don't wish to migrate the apps, just the user settings and the data. I will make an entire backup of the user directory on a separate drive before I start this process, as well as a Time Machine backup. I then plan to migrate the account settings and data, but manually reinstall the extra apps. The reason for this is I have a lot of third party apps, and some are trials I decided to uninstall, and they all leave junk behind.
3. If I import the user account settings and data only, what cruft or orphaned files should I be aware of?
4. Are there options to cherry pick the settings that are migrated?
5. If I manually copy, for example, the mail folder, iCal or messages folder in my user library, and place it into the appropriate user folder in the new account in a worst case scenario, will there be any drama I should be aware of?
Lastly, a question of Apple ID's/iCloud:
6. Before doing this process, should I deauthorise my iTunes account, or will that be fine when migrated anyway?
7. What will happen with my iPhone when I sync to a fresh install on mavericks, will it attempt to wipe my iPhone, or is that part of the user data that is migrated?
Thank you for your time and patience reading this!

1. I'd go with at least 40 because you need some extra disk space for the computer to work properly. You can install that one partition, load it, and see how much disk space is used and adjust as required. Also boot from it and make sure it runs okay.
2. Everything but the Apple applications, which you probably won't be able to delete.
Mavericks
Almost all applications are stored in the hard drive level Applications folder. Check your user applications folder and if there are no applications, just copy the entire user folder.
3. Hard to answer. In theory, none.
4/5. They may not work due to differences between 10.8 and 10.9. You might want to consider using Setup Assistant and restore from Time Machine. Then delete the stuff you don't want.
6. Shouldn't matter - same computer. I have 2 partitions and both are authorized for iTunes and the App Store.
7. If you restore from Time Machine, you should be okay.

Can I dual boot Mountain Lion and OSX10.6.8

Can I dual boot Mountain Lion and OSX 10.6.8. I just upgraded to Mountain Lion and my InDesign CS2 no longer works. If yes, how does one do it.
Thanks all,

Yes, as long as your computer shipped with 10.6.8 or earlier. Insert the Mac OS X 10.6 DVD, restart with the C key held down, and install it onto a separate partition or drive; if you use Boot Camp, repartitioning the internal drive may disable it.

Dual boot for lion and SL

BHow do I set up the dual boot for Lion and snow leopard oon the same internal hard disK
What does Time machine do under the dual boot?

I am also considering putting Lion and SL on separate hard drives.
Since this is an iMac forum, I assume you will use an external drive as the second drive. Use one that connects via firewire, not via USB.
Both on a single drive -
OK. Doing it on a single drive means you will need to partition the internal drive. Although this is straight forward, it is always best to back up the existing drive first, just in case. It's a good idea to have a backup on a different drive, anyway.
To do that, clone the entire internal drive to the external drive.
I would suggest, though, that you first partition the external drive. I would suggest four equal-size partitions, provided the drive is big enough - at least 1.0TB, though a 2.0TB drive might be better. You can use OS X's disk utility to do that. Go to the Partition page in Disk Utility, select your external driv in the list on the left, then use the Partition Layout menu to select the number of partitions. Set the format to Mac OS Extended (journaled) GUID for all partitions. Click the Apply button.
The easy way to do the cloning is to use a cloning utility such as Carbon Copy Cloner. Clone the entire internal drive to one of the partitions on the external drive. Then test boot to it (use Startup Disk in System Preferences to do that) to verify the integrity of the clone. At that time I would suggest you change the background design/picture for the desktop to aomething other than the one used on the original drive - this can be a handy visual reminder of which volume you are booted to.
Then add a partition to the internal drive. To do that, run Disk Utility. Go to the Partition page, select your internal drive in the list on the left, but do not use the Partition Layout menu this time. Instead, click the existing volume in the graphic display, then click the plus ("+") button underneath that display -
This will add a partition without erasing the existing information - i.e., the drive will end up with two partitions, one of which will contain your original boot volume.
Use Startup Disk to re-select your original boot violume, and restart back into it.
Now, clone the original drive again using CCC, but this time to the second partition of the internal drive, the one you just added.
Boot to that freshly cloned volume to verify it. Then, while still booted to it, install OS X 10.7 Lion onto it.
This will result in your original Snow Leopard on the first partition of the internal drive, and Lion on the second partition of the internal drive.
The external drive will have Snow Leopard on one partition, one partition will be empty (available for a clone of Lion if you wish, or use it for extra storage). The remaining two partitions can be used for Time Machine backups - one for Snow Leopard, one for Lion.
If you want to have each OS on its own hard drive, then you can use the first clone of Snow Leopard to the external to be upgraded to Lion, or upgrade the orignal on the internal drive to Lion. Be sure to boot to the volume to be used for Lion before installing it so that Lion is installed onto the correct boot volume.
You can then use the empty partition on the internal drive as the backup (or Time Machine) volume for the OS on the external drive, and vice versa. In this arrangement you may need only partition the external into two volumes.
If you have a different scheme in mind for partitioning, feel free to do that. I don't use Time Machine, so don't have the need to make space for it. Carbon Copy Cloner can be used to do incremental backups after the initial backup - but I don't use that, either. I'm old school - after the inital cloning for backup, I do manual backups of files on the fly.
Comments -
* I would suggest keeping both Snow Leopard and Lion on the internal drive. Reason - even though firewire 800 is fast, it is still noticeably slower than an internal drive. OS's on an external drive will run slower than those on an internal drive.
• I don't like the concept of Time Machine. Amongst other things, it seems to want more space on the target volume than it actually needs; and it is not a bootable replication. A clone of a bootable volume is bootable.
• It was just a few days ago that I went through the same process as you are planning. One slight difference - I used a 1.0TB external partitioned into 3 equal volumes, since I had no need to allow space for Time Machine. I have Snow Leopard and Lion each on its own partition of the internal drive; and cloned backups of each on the external drive, plus one GP partition on the external drive.
• If you have not yet downloaded Lion, be prepared for it to take a while; it's almost 4GB in size. Probably be a good idea to defeat sleep for the duration.
• Cloning takes a while, but not that long - it took 30 minutes to clone 45GB to the external drive, and 45 minutes to clone it to the second internal partition.

HT4889 Trying to migrate from Mac-mini Tiger to Mac-mini Lion and Migration Assistant cannot find my Firewire, 400 to 800, "T" disk although it show up in the new Mac's computer folder. Help

Trying to migrate from Mac-mini Tiger to Mac-mini Lion and Migration Assistant cannot find my Firewire, 400 to 800, "T" disk although it shows up in the new Mac's computer folder. It seems that Mac-mini Tiger is as it should be and the firewire cable is OK. Something about the Migration Assistant is being missed, but I have no idea what it is.
Help

Addendum: I read on a post here (http://forums.macrumors.com/showthread.php?t=420169) about removing some kext files in order to trick OSX into thinking that there were no FireWire ports.
I followed the instructions and removed from /System/Library/Extensions/ the following files:
IOFireWireSerialBusProtocolTransport.kext
IOFireWireAVC.kext
IOFireWireFamily.kext
IOFireWireIP.kext
IOFireWireSBP2.kext
I restarted and BAM...Snow Leopard booted crazy fast and the mouse and keyboard worked instantly.
The System Profiler says "No FireWire ports were found."
So this tells me that the FW port is probably the culprit and is messing up the installation.
So how do I hack the Mountain Lion installer and tell it to ignore the FW port, which is obviously quite dead? Or is there something I can do to the Base system that is similar?

Dual boot with lion and mavericks?

Hi Guys,
I want to updgrade to mavericks as well as keeping lion to run my old soundcard { no new drivers will be made } so, I'm thinking of using my external hard drive to try and install mavericks onto and Dual boot my MBP.
is this possible?
Cheers, Iain.

Hi Mate,
I'm currently backing up my hard drive and then I'm going to download mavericks.
After the download completes you get this screen:
Quit without pressing the install button. Go to the applications folder and make a copy of the installer, move the copy out of the applications folder. When the copy is done doubleclick the installer in the applications folder.

How do I dual boot Mountain Lion

I recenetly purchased a new iMac with Mountain Lion installed on it. My previous Mac runs Lion. I still have a few apps which I need to support older devices for and need to run an earlier version of xCode than is allowed on Mountain Lion. My hope was to setup a dual boot system with both Lion and Mountain Lion to do this. So far I have not been able to figure this out. I've tried to follow walkthroughs on the web, but they were all had Lion and were making a Mountain Lion partition. Any input would be much appreciated.
Thanks,
Scott

Yep. Your new machine can only be started with the version of Mountain Lion with which it came.
There isn't much you can do. If you wish to spend money you can purchase Parallels 8 for OS X and try running Lion or Snow Leopard in emulation. See Running Lion as a Guest OS in Parallels Desktop 7 - YouTube.

Mountain Lion re-install has migration assistant options greyed out. How do I choose only data I want?

I ran out of space on my Mac Mini so I bought the iFixit kit and added a second drive. This resulted in me putting a 60GB SSD system drive and a faster 7200 RPM 500GB data drive in the mini. I removed the original 500GB drive and placed it in an external enclosure.
After installing Mountain Lion I ran migration assistant. It shows all the data from the external drive, but everything is checked and it will only migrate to my 60GB OS drive. Of course this won't work.
I made a link to /Users to my second internal data drive but migration assistant still shows a -486.34GB of space needed.
So, instead of taking a week to upgrade my App Store purchases and install and configure everything (Mountian Lione Server, Xcode, Microsoft Office, Parallels...) how can I get migration assistant to allow me to just choose specific items to migrate?
As a side note, how can I make Mac OS X Mountain Lion use the second internal drive for User accounts *AND* recognize it properly? My link works but I'm early into this and would rather do it 'right' now then live with frankenmac later.
Thank you,
-Tim

Well, maybe I posted to the wrong forum...
I went in to speak with a mac genius too. All I got was, "In all the years I've worked on Macs, I've never seen the migration assistant with greyed out options." Ok. I guess I have more experience, I've seen it. They then suggested I run check permissions on the drive and buy Disk Warrior for $100. Sorry guys, the drive is fine. My TM backups are fine. It's not that.
I went ahead and bought a 1 TB drive. Even then, the migration assistant choices were greyed out. I went ahead and created a Fusion drive to take advantage of the SSD (the 1TB is only 5400 RPM). The directions can be found here. I then just ignored the greyed out options and brought *all* the data over to the 1.1TB drive. Everything works fine.
I'm bummed about not getting the apps and O/S pinned to the SSD but I figure if anything is getting used a lot, its where it needs to be.

Did a clean install of Lion and Migration Assistant doesn't...

...recognize my external Time Machine drive. (It was mounted and displayed on the desktop.) I need to bring over my Time Machine Settings so I can use my old Time Machine backups with the freshly installed iMac. I also need to copy over my iTunes settings, as my iTunes database for music and apps is located on a (different) external drive. I am willing to copy things over manually, if necessary. Are there any directions somewhere for how to do this? Thanks.

Using a time machine backup of Mountain Lion on Mavericks

I have just installed Mavericks with a clean installation from Mountain Lion. I have a time machine backup of Mountain Lion, but I do not want to use this backup to restore my system because I have a lot of problem and I would like to be sure that is not a problem connected to the software.
Can I use the previous time machine disk as backup of the new operating system without losing the previous backups?
If I use it, I cannot restore the system with the "Mountain Lion" state with the migration assistant, is it true?
Thanks

No. Time Machine will be replacing your existing backup with a new one of your Mavericks system. If you wish to replace Mavericks with Mountain Lion, then I suggest you replace it with another backup of Mountain Lion, if you have one. Otherwise, if you've permitted Time Machine to run since installing Mavericks, then you not longer have a Mountain Lion backup.
You will need to go to your Purchases page in the App Store and try to re-download your Mountain Lion purchase. If you can, then after the Mountain Lion installer downloads and opens quit the installer - do not run it. Now do this;
Make Your Own Mavericks, Mountain/Lion Installer
After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. 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.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list.
Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
Use DiskMaker X to put your installer clone onto the USB flash drive.
Make your own Mavericks flash drive installer using the Mavericks tool:
You can also create a Mavericks flash drive installer via the Terminal. Mavericks has its own built-in installer maker you use via the Terminal:
You will need a freshly partitioned and formatted USB flash drive with at least 8GBs. Leave the name of the flash drive at the system default, "Untitled." Do not change this name. Open the Terminal in the Utilities folder. Copy this command line after the prompt in the Terminal's window:
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
Press RETURN. Enter your admin password when prompted. It will not be echoed to the screen so be careful to enter it correctly. Press RETURN, again.
Wait for the process to complete which will take quite some time.
Now, run the installer flash drive, erase the hard drive, and reinstall Mountain Lion. You can then use Time Machine just to replace your data from your Home folder.

IMac CPU3.06 GHz Intel Core 2 Duo, 8GB, Extremely slow and repeatedly "out of Memory" since migration from Mountain Lion to Mavericks

Dear Apple Support Community.
As mentioned by a number of users reporting the same problem, my 2009 iMac CPU3.06 GHz Intel Core 2 Duo, 8GB RAM, has become extremely slow and repeatedly "out of Memory" since it was migrated from Mountain Lion to Mavericks (OS 10.9 then OS 10.9.1).
I have already run CleanMyMac, deleted 5GB of useless stuffs, which did not translate into any improvement. Following the advices collected in other Apple Support Community threads, I have applied EtreCheck the outcome of which is provided below.
For information, I have also upgraded my 2011 MacBook CPU2.3 GHz Core i7, 8GB which became only a bit slower than before, sometimes freezing which it almost never did before. However, I am used to the fact that Mac get usually slower and more prompt fo freeze after upgrading to a more recent OS.
Both my 2009 iMac and my 2011 MacBook have F-Secure installed. So the problem with the 2009 IMac is unlikly to be due to the presence of F-Secure. Interestingly, the few abnormalities found by Etrecheck were exacly identical before I ran CleanMyMac. There are two more findings (mentioned below) since I ran CleanMyMac on the 2009 iMac, which again didn't improve the problem.
So please find below the details of the EtreCheck experience and some additional measurements made with iStat while running EtreCheck:

If trying to write a mail (with Mail) while Safari or Firefox is open, then the "out of Memory" message occurs about every 20 seconds so I need to check on "Resume" several times per minute.
Conclusions
From the above, unless anyone in the Apple Support Community proves to be able to identify a specific problem leading to a way to find a cure, I tend to conclude that Mavericks is not suitable for computers operating with a Core 2 Duo CPU even with a 8GB of RAM.
Unless I missed something, I did not see any warning from Apple Computer Inc. informing their customers they should refrain from upgrading Core 2 Duo Computers.
The only solution I see so far is to downgrade from Mavericks to Mountain Lion. And the Apple Support Community would confirm that it is the only solution, I would appreciate to get your guidance on how to proceed.
Intended action plan
Migrate the above 2009 iMac to a 2014 Mac Mini Server operating on Mavericks to ensure that no data may be lost while downgrading to Montain Lion.
Provided the above downgrading operation is successful, assign this 2009 iMac to partial retirement e.g. Mail, Skype, iTunes and DVD player.
In advance, I would like to thank the Apple Community for helping me either i) finding a cure to the problem, ii) or confirming that Mavericks cannot operate properly on Core 2 Duo computers, iii) and in such a case, guiding me on how to downgrade to Mountain Lion.
Yours sincerely
Core

... what anti-virus would you recommend using?
Use what is already included with OS X. It already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Disable Java in Safari > Preferences > Security.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

Can I dual boot snow leopard and mountain lion if I've installed boot camp on my drive

Can I dual boot snow leopard and mountain lion if I've installed boot camp on my drive

Yes as I said before. If your model Mac came with Snow Leopard and you are now running Mt Lion and have Windows installed in a Boot Camp Partition all you have to do is make the Mt Lion partition smaller, take the free space and make it another Mac partition and you should be able to install Snow Leopard into that partition.
I have Snow Leopard, Lion and Mt Lion installed on my MBP. No Windows in a Boot Camp partition because I run Windows XP in a Virtual Machine on both Lion and Mt Lion.

Dual boot drive - Mountain Lion and Snow Leopard - Correct order to load software /apps?

Hi
I want to create a dual boot drive for Mountain Lion and Snow Leopard as some of my hardware (is not supported in Mountain Lion).
I am happy how to do this, I just want to know if there is a correct way to install software and apps.
My plan was to do a clean install of both using two partitions, the larger going to ML and smaller one for SL. I was going to install SL from the DVD and then after updating from 10.6. to 10.6.8 and download ML from the app store and install on the larger partition.
Do I install all the software I use like Final Cut, Aperture, iLife (for Garageband) etc on the ML or SL partition or on both. Also, is there a better way / practise of the order software updates / apps and boxed software should be installed when doing a clean machine install.
Thanks in advance.
Matt

Thanks mende1
So, if I have software I need to use on both ML and SL - for example Final Cut as I have a Canopus AVDC box which is not supported in ML but only SL, do I need to install the same software in both OS?
I usually open apps using spotlight and didn't know if it would software / apps would open if already installed on the other partition?
Thanks again

Can I erase the boot camp partition and dual boot snow leopard and mountain lion instead

Please don't double post. Look at your other thread.
If you want to get rid of Windows and the BC partition use the Boot Camp assistant program to remove the Win/BC partition. Don't do it manually with Disk Utility Use the BC A program.

Can I install Mountain Lion and Mavericks on same computer

Stupidly I installed Mavericks over Mountain Lion without checking whether Quark XPress 9.5.3.1 would work with Mavericks.
It won't.
I have re downloaded Mountain Lion and need to know whether I can run both on same computer - and how to do that - any help appreciated.
Thanks.

Sure you can. Erase one of your partitions and install the OS of your choice on it. You can have as many operating systems on a Mac as you want. Use Startup Manager to select the OS you want to boot. Virtualization software is another option.
Both the Mavericks and Mountain Lion installers will permit you to select the partition on which it is to be installed.
If you don't tell us the errors that resulted from using Lion Disk Maker no one can begin to guess the reason, but no matter, you don't need the USB installer. Just use the App Store.
You can save the installer anywhere you like to use as often as you wish, so you don't have to download it each time.
It looks like this
You have to copy it before running the installer because the installer conveniently erases the 5+ GB file after the installer is finished with it.

Resetting your Mac's PRAM and NVRAM
Intel-based Macs: Resetting the System Management Controller (SMC)
Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Reinstalling Mavericks, Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion, Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
