Mountain Lion Cloning

One question on cloning a brand new drive using Disk Utility. The boot drive in this iMac has a 1 TB capacity, but after installing the Adobe Suite, Office and a few other essentials, still only utilizes a fraction of the drive. Do I need a destination drive that equals the total capacity of the boot volume, or enough to hold everything that's on there now?
My goal is to save time setting up new work stations by using this clone for the initial setup.
Thanks for any opinons.

The clone will take up the same "Used" space as the original, so no need to use a 1TB drive, just give it a bit of breathing room.

Cloning Snow Leopard from old iMac onto New iMac with Mountain Lion.

Hi all.
My old late 2006 intel iMac (2.1Ghz, 24" white) packed in a few weeks back (most likely GPU fail, but that's another topic!).
I've picked up a good deal on a second hand machine (funds wouldn't stretch to brand new model, but iMac definitely required):
2.7Ghz, 2011 i5, 1TB, 4gb RAM (will increase that) running mountain lion.
Ran a few tests on the old machine and the Hard Drive looked absolutely fine (was new just over 18 months ago) and could be accessed via another machine.
That was running Snow Leopard (upgrade from original OSX back in 2006) and easily ran FCP and Logic Pro post upgrade to SL.
What I would like to do really is clone my old hard drive (and I have a time machine back up on an external drive) onto this new machine. However, I'm not quite sure whether I'd lose Mountain Lion (if my old s/w such as Logic Pro 7 and FCP suite will run ok on ML I'd like to keep it as I quite like it.
Not having any discs with this iMac (Mountain Lion not requiring them), would I be able to re install Mountain Lion if I'd cloned a Snow Leopard drive onto it?
Apologies if this is an obvious question!! If I could still run FCP and Logic successfully on Mavericks, I might even upgrade to that also (not sure yet!).
Given the price of the thunderbird cables I'll be using a FW800-FW400 (cost 4x as less) to transfer. I'll probably use 'super duper' to clone.
Am I along the righ lines folks?
Many thanks.

I only mentioned partitioning because you indicated that you wanted both Snow Leopard and Mavericks capability on the newly acquired iMac. Of course, you cannot have both flavors of OS X on the same hard drive unless it is partitioned to keep them separate.
Once you have Snow Leopard in one partition and Mavericks in the other, "dual-booting" is simply the process of determining which flavor or OS X will be operating by using the Startup Manager in System Preferences before you reboot, or holding down the OPTION key while you do reboot.
The disadvantage to this approach is that you cannot have both Snow Leopard and Mavericks running concurrently. To have that capability, you must install Snow Leopard Server into a virtualization program such as Parallels running in Mavericks and then they can run concurrently:

Mountain Lion Hangs on Boot when an external cloned drive is attached

It seems that, for me at least, when I have an external drive, in this case a usb, plugged in on boot up, Mountain Lion just hangs. This external drive is used as a clone (I use Super Duper). It can hang in one of 2 places; after inputing my password, or when trying to bring up the desktop. It is very consistent as to the hanging. When the external drive which contains the clone is not attached, it boots fine every time. I have no problems at all with my other external drives being plugged in at boot. They are just contain data. Is Mountain Lion getting confused? Anyone else experience this?

I am stumped too. The issue is that the 'pmset -g' command does not allow changing the ExternalMedia flag.
An observation that may be relevant to this topic is as follows: if you unmount the drive (but not physically disconnect it), sleep comes in the specified time. Upon wakeup, however, the drive is mounted again to the desktop. I've noticed this behavior with SD cards, and I assume that HDs should do the same.
If this is the case, then it may be possible to use ControlPlane (current version is ControlPlane-1.1.4) and create an "about to sleep" situation, which triggers USB disk unmounting. Haven't tried it, but was thinking to (subsequently just gave up and eject my USB storage manually).
Hope this helps.

Cant use CCC to clone Snow Leapord mac to Mountain Lion mac

hello all,
I just bought a MacBook Pro (Mid 2012 not retina), and it came with Lion OSX. I recently installed Mountain Lion OS and it appears to be working welll except I am having trouble using a cloned external drive. I cloned my 2007 MacBook (Snow Leapord), using CCC (Carbon Copy Cloner), onto a Seagate 320GB eternal USB Hard Drive. When I plug the drive into my new MacBook Pro with Mountain Lion, and go to system Preferences, startup disc, select the coned drive, and click restart, the computer shuts down and appears to be starting to restart, but it just stays on the white screen before the apple symbol shows up and the apple symbol never even pops up, it just stays white forever without booting up. Now, I tried using the drive as a startup disc for my dad's 2008 MacBook Pro with Leapord and it worked like a charm and also tried it on my sister's MacBook Pro (Lion) and it worked fine there too. Is there something about mountain lion that could be causing this problem? I even tried using Target Disc from my old mac (that i cloned) to my new one and it wasnt working either. If anyone has any ideas, please help! Are there any particular tricks to using CCC for Mountain Lion? Thanks for the help!!!

Thanks that makes sense, however, my sisters Macbook pro worked with it and hers is a 2011 and came with Lion, so I'm not sure what to make of that.
Right the Early 2011 model MBPs came originally with Snow Leopard installed and Apple updated SL to 10.6.8 to work correctly with the newer hardware in the Early 2011 models. Then in June Lion came out and then all shipping MBPs came with Lion Pre-Installed but they would still run SL if you had the 10.6.8 version of SL. Since the Late 2011 models were basically the exact same computer, just upgraded CPU and some other minor changes, as the early 2011 models even though the late 2011 models came with Lion Pre-Installed SL would work on those if you had the 10.6.7 or .8 version of SL.
Now with the newest Mid 2012 models all of the Base hardware was changed to the most current versions available, New hardware. Even Lion that worked on the late 2011 models will NOT boot on the Mid 2012 models.
The 2011 version/build of Lion does not have the correct driver package to work on the new hardware.
Apple put together a Special build of Lion to work on those newest system with an updated driver package for the newer hardware.

2008 iMac upgraded to Mountain Lion now boots slowly?

We have an Early 2008 Aluminium iMac. 2.4 GHz Core2 Duo, regular HDD. I think it came with 1 GB of DDR2 RAM but we upgraded to 2 GB. It originally came with Leopard but we upgraded to Snow Leopard on short order. So everything was good, maybe when it was brand new it would be ready to use in 25-30 seconds and after four years it would usually boot and be ready to use in 30-45 seconds. Pretty quick, maybe due in part to a hard drive that was mostly empty (don't know if that matters).
But then when Mountain Lion came out, I wanted to upgrade. I swapped out the 2GB of RAM for 4GB, ran the installation tool, and that was that. However, ever since then, boot time takes at least twice as long. (Both takes longer to get to desktop and takes longer for desktop to be ready for me to launch apps.) I knew it uses a little extra RAM but I didn't think it should be so bad for performance. I've reset PRAM and repaired permissions and all that boring stuff already, but it doesn't help.
I suspect there is just something that could be fixed so it doesn't take so long, like some caching setting or something (I really have no idea what I'm talking about) or that if I do a fresh install it *should* go back to booting in 30 seconds. However I don't want to spend half a day reinstalling and restoring on a hunch. So what are your suggestions?
I also plan on upgrading to OS X Mavericks in the fall as it seems like it includes performance improvements (not sure if it'll matter for boot though). Might upgrading to Mavericks "fix" some messed up setting that slows down boot time? Or would it not make any difference? Or would I have to do a fresh install when I upgrade to Mavericks to avoid a slow boot time? Or should I just wait till I want to upgrade and then do the whole fresh install and restore files/apps/settings from my time machine backup (or better to do manually)?
I'd like to add also that I have a MacBook Pro with an SSD and 4GB DDR3 RAM that came with Lion, and doing the same kind of upgrade process to ML as I did on the iMac didn't effect boot time on the MacBook Pro (it's still about 15 seconds).

Hello Mac OS XP,
While your iMac is within the scope of supported machines for Mountain Lion, it is pretty far down the spectrum. Every new OS will require more resources than the one before it wether thats processor, RAM or graphics power. I would personally keep a machine like that on 10.6 Snow Leopard for best performance. Anyway, it cán handle Lion or Mountain lion but it will perform slower than it did under Snow Leopard.
That said, upgrading an OS that has been upgraded in the past and then skipping a version to the latest OS, there are usually some complications. There are a few things you can try to get some performance back but at this point i do recommend backing up your machine, re-format the drive, install a clean copy of Mountain lion and then restore your data.
You have tried the permissions repair which is always a good first step. (backup before you continue) Next restart your Mac, hold down the Option key as soon as you hear the startup chime and select your recovery partition as your startup disk when it pops up on the screen. From there, open disk utility and instead of repairing the permissions, run a Verify on your hard drive (and a Repair, if needed). Quit Disk Utility and the Recovery window and you can select your main partition as startup disk again and restart.
If repairs or modifications were made by Disk Utility, it may actually take even longer to start up now but that's just the first time, if you restart again you'll see if you actually gained performance.
If that did not work, i'd start over. You may spend more time trying to figure out and test different fixes than it would take to just re-install and enjoy a clean OS.
While Time Machine is an option, in this case i would Clone the drive with a utility like SuperDuper. Personal preference and when it comes to multiple OS upgrades etc. i find it more reliable than Time Machine which is pretty complex in it's own way. A benefit of a cloned drive is that it's bootable. If something goes wrong or your internal drive breaks in the future, you can start up from the clone drive and just keep on working (it'll be slow if it's a FireWire drive and even slower if it's USB but you'll be able to work and access your data).
Someone else may come along to suggest other things to try so if you are not in a hurry i'd give this post a little more time to be seen by others. I would make that clone or time machine backup, your choice, now though as most suggestions and recommendations you'll get are pretty invasive.

Time Machine backup on Mountain Lion not restoring

I recently upgraded from Lion to Mountain Lion. After the upgrade, I duly take back ups to my two existing time machine back-ups on two external hard disks. I also maintain a separate CCC bootable clone. I recently tried to restore my calendary folder to restore data on my Calendar application but I got the shock of my life when I realised that NO mountain lion restores are working using either of my time machine back ups. BTW I have previously upgraded to Snow Leopard and to Lion, and my Time Machine backup disks have never showed any problems.
I have spent the last 4-5 days trying a variety of solutions, with no luck so far:
1) I looked at Pondini's website, including restoring data from TimeMachine backup to a dmg image and copying. This failed due to a combination of permissions error and wrong information about size / disk space requriements. In any case, this is not a feasible option since I would prefer restore to work directly, especially for large files and system files, as it did before since this workaround is not really a solution.
http://pondini.org/TM/E10.html
2) I followed instructions given at http://superuser.com/questions/35152/how-do-i-retrieve-files-from-time-machine-b ackups-from-another-computer and set ignore ownership via command line and then backed up again, but this did not fix permissions either on the new backup.
3) I used a separate external hard disk, reformatted it as Mac OSX journaled (not case sensitive) using a GUID partition map, and then backed up my hard disk (~330GB) which took ages but the new time machine back up does not work either. I still get permissions errors on restore from TM backup.
4) Using yet another hard disk, I followed advice here:
http://support.apple.com/kb/HT5096
This has not worked either - I still get permissions errors on restore from TM backup.
5) If I go back to a TM backup dated PRIOR to upgrading to Mountain Lion, all restores work fine from both my exisiting time machine backups. It seems to me that only post Mountain Lion upgrades which don't work. So my conclusion is that it is ML that has introduced some sort of permissions issue.
6) File restores (i.e. copy paste to my desktop) from the CCC cloned backup proceed wthout a hitch.
At this stage I all I am really trying to aim for is getting a working time machine backup, even if it is a new one which restores properly. That is proving to be a huge challenge. Any help or advice would be very useful indeed. The only option left for me is to now either go to an Apple Store or to call Apple Care, but I am not confident of securing a resolution at either place. So any advice from more experienced users would be very much appreciated. Thanks in advance.

How do I download Mountain Lion on an old mac?

I have been relentlessly trying to update my mothers Mac. She has an older version of OS X, 10.5.8. I was attempting to download Mountain Lion, but I for the life of me could not get it to work. I have emailed Apple several times with no reply. How do I go about updating her mac to Yosemite?

Before embarking on a major OS upgrade, it would be wise, advisable and very prudent if you backup your current system to an external connected and Mac formatted Flash drive OR externally connected USB, Thunderbolt or FireWire 800, Mac formatted hard drive. Then, use either OS X Time Machine app to backup your entire system to the external drive OR purchase, install and use a data cloning app, like CarbonCopyCloner or SuperDuper, to make an exact and bootable copy (clone) of your entire Mac's internal hard drive. This step is really needed in case something goes wrong with the install of the new OS or you simply do not like the new OS, you have a very easy way/procedure to return your Mac to its former working state.
Then, determine if your Mac meets ALL minimum system install requirements.
Mac OS X v10.6 Snow Leopard system requirements
Purchased Installer disc here.
http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard
To install Snow Leopard for the first time, you must have a Mac with:
An Intel processor
An internal or external DVD drive, or DVD or CD Sharing
At least 1 GB of RAM (additional RAM is recommended)
A built-in display or a display connected to an Apple-supplied video card supported by your computer
At least 5 GB of disk space available, or 7 GB of disk space if you install the developer tools
OS X Lion system requirements
Purchased emailed download code here.
http://store.apple.com/us/product/D6106Z/A/os-x-lion
To use Lion, make sure your computer has the following:
An Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
Mac OS X v10.6.6 or later to install via the Mac App Store (v10.6.8 recommended)
7 GB of available disk space
2 GB of RAM
To install OS X 10.8 Mountain Lion, 10.9 Mavericks (currently unavailable) or OS X 10.10 Yosemite.you need one of these Macs:
OS X 10.8 Mountain Lion purchased emailed download code here.
http://store.apple.com/us/product/D6377Z/A/os-x-mountain-lion
iMac (Mid-2007 or later)
MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
MacBook Pro (13-inch, Mid-2009 or later),
MacBook Pro (15-inch or 17-inch, Mid/Late 2007 or later)
MacBook Air (Late 2008 or later)
Mac mini (Early 2009 or later)
Mac Pro (Early 2008 or later)
Xserve (Early 2009)
Your Mac also needs:
OS X Mountain Lion, Lion, or Snow Leopard v10.6.8 already installed
2 GB or more of memory (I strongly advise, at least, 4 GBs of RAM or more)
8 GB or more of available space
Next,
If you run any older Mac software from the earlier PowerPC Macs, then none of this software will work with the newer OS X versions (10.7 and onward). OS X Snow Leopard had a magical and invisible PowerPC emulation application, called Rosetta, that worked seamlessly in the background that still allowed older PowerPC coded software to still operate in a Intel CPU Mac.
The use of Rosetta ended with OS X Snow Leopard as the Rosetta application was licensed to Apple, from a software company called Transitive, which got bought out, I believe, by IBM and Appe could no longer secure their rights to continue to use Rosetta in later versions of OS X.
So, you would need to check to see if you have software on your Mac that maybe older than, say, 2006 or older.
Also, check for app compatibilty here.
http://roaringapps.com/
If you have any commercial antivirus installed and/or hard drive cleaning apps installed on your Mac, like MacKeeper, CleanMyMac, TuneUpMyMac, MacCleanse, etc. now would be a good time to completely uninstall this apps by doing a Google search to learn how to properly uninstall these types of apps.
These types of apps will only cause your Mac issues later after the install of the new OS X version and you will have to completely uninstall these types of apps later.
Once you have determined all of this, you should be able to find the latest versions of OS X by clicking on the Mac App Store icon in the OS X Dock and then login to the Mac App Store using your Apple ID and password and if you purchased a download code, input that code.
You can then begin the download and installation process of installing the newer versions of OS X from the Mac App Store.

I installed 6.0.2 on OS10.7.5 and now Safari won't open. 6.0.2 is just for Mountain Lion. How do I revert to 6.0.1?

I installed 6.0.2 on OS10.7.5 and now Safari won't open. 6.0.2 is just for Mountain Lion. How do I revert to 6.0.1?

I do have a cloned back-up, so I tried to just copy Safari 6.0.1 back onto my main drive—wouldn't work. Got a message that the System needs Safari and I can't touch it.
I'm trying to find a simpler way to revert than clone backwards, which takes a lot of time. And actually I never use Safari. I'm a Chrome user.
You are correct that I downloaded 6.0.2, rather than using software update. However, with many other pieces of software, if you try to install over the wrong system, you get a message telling you that the installation can't be done. Apple could have saved a lot of trouble by using this message.
I have three machines of different vintage, so one is on 10.6.8, one on 10.7.5 and one on 10.8.2. I am usually pretty careful about software updates and which system is needed. Unfortunately, in this case I used CNET download, and the description of 6.0.2 said it was for Lion and Mountain Lion.

No Recovery - Mountain Lion won't install but Lion Recovery worked (until Mountain Lion messed it up).

When I tried to install Mountain Lion it gave me the "this disk does not support some features, like FileVault or Recovery Mode..." message. However, my Lion install at that point had a working Recovery Partition (I confirmed it after I got this first message - booted with it). I also have a cloned backup so I clicked continue. The install failed and gave the "No Recovery" message. Then I tried to boot in Recovery Mode and a screen came up saying "Installing" and the giant X with what looked like a progress bar with diagonal blue lines moving left to right, but no "time remaining" or other info indicating it was doing anything. I let this go on for about 10 or 15 minutes then restarted my computer. In Disk Utility I repaired permissions and disk repair was ok. I'm not using RAID or BootCamp - just one partition (plus the Lion Recovery one. The Mac is a newest model MacMini with an OWC SSD (I first thought the SSD might be the problem but it worked with Lion, so...)

Just Follow this procedure...
1. Go To BOOT CAMP and create a BLANK PARTITION. Say a minimum of 10 GB. You do not have to install anything on this.
2. After you create this, go back to ML installer and now you will see 2 HD's. one will be your main HD and the second one will be the one you just created.
3. Install the ML OS X on the main hard drive. Once installed, reboot the machine go to DISK UTILITY and delete the blank partition you had created.
4. So, now you have your HD at its full capacity.
Try this it should work.

My Macbook Pro is running Leopard 10.5.8 and I want to install Mountain Lion

What are the steps for doing this?
I bought a used Macbook Pro (late 2008-2009 silveraluminum 250 GB HD model) after recently buying a new Macbook Air that I broke. My Macbook air was a 2012 and came with Mountain Lion 10.8 preinstalled (as there are no CD slots on the Air models). I do have an external hard drive and I had been using that as my time machine backup. Consequently, my entire Macintosh HD has been cloned from my Macbook Air onto my western digital external HD. However, I cannot restore from my time machine backup (external HD because it says that I do not have the same operating system currently installed on my laptop.
What do I need to upgrade to the newest Mountain Lion operating system? Do I have to buy snow leopard and then again mountain lion? That seems pretty ridiculous. Or, is it possible to just buy the mountain lion OS from the app store or buy the installation CD?
Another question, is I do not see the App store icon on my dock when I have my desktop up. How would I buy Mtn Lion if I cannot access App store. Does Leopard not have an app store app??
Please provide links where I can find necessary software updates and steps to take to get mtn lion so that I can transfer my clone HD off my external hard drive to my laptop I just bought.

First you have to get the Model Identifier from System Profiler, then make sure of it's model and RAM amount, then use Crucial.com or OtherWorld Computing and max out it's RAM capacity.
There is a 10.5 version of MacTracker here that can assist in getting the full RAM capacity of the machine, not just the amount Apple provides, and the RAM specs.
http://mactracker.ca/archive.html
Install/upgrade RAM or storage drive in Mac's
Also a machine that daed is likely got a dying boot hard drive, so you should replace that also with something like a 7,200 RPM for better performance, large storage capacity and decent price. A SSD would be price overkill for that older machine and add another level of problems enabling TRIM support etc.
Next you need the 10.6 white retail disk Apple sells online.
Next you follow this User Tip for installing 10.6 on the new drive. It is advised to Zero Erase the entire drive regardless of new or the old one.
How to erase and install Snow Leopard 10.6
Once 10.6 is installed you use the 10.5 disks to install your free iLife, then use Software Update repeatly until clear to get to 10.6.8 which provides AppStore for 10.8 install (paid).
Now comes the problem. Later OS X verisons of 10.7+ are better on MacBook Pro's Early 2011 and later, the performance drops off if you use machines earlier than 2010 models.
It's because 10.6.8 was written to be a performance oriented with a small memory footprint thus it's better in tune with the processors and graphics potential of the models in it's day.
10.7+ are fully 64 bit operating systems and require a heft bed of RAM, 4GB minimal and a lot more preferred., it's why I provided the MacTracker info so you can put the maximum RAM into the machine and a faster boot drive, with RAM it's usually MORE can be put in than Apple specifies.
If you can think you can live without 10.7+, then by all means enjoy the performance 10.6.8 gives, at least with that version of OS X you can stick with the hardware that came with the machine. For Snow Leopard Speed Freaks
I say this because a 2008/2009 machine is 5 years old and on it's deathbed far a laptops typically go, so it doesn't have much left in it. It's cooling fins are likely clogged with dust (behind the fans) it's been overheating with the previous owner, the Superdrive is likley worn out and they sold it for a good reason, like that it was going to need a lot of upgrading to bring it to 10.8 only to have 10.9 released in a few months and it will be behind again, or denied being allowed to go to 10.9 or later by Apple due to the age of the machine and unsupported graphics or other reason.
Buying that machine for 10.8+ was not a good choice because of the upgrades required and the poor CPU/GPU performance. It wil run 10.8 of course, just not as snappy as 10.6.8 will be or 10.8 was on your Macbook Air.
If you can live without iCloud, 10.6.8 has over 25% market share still and Apple is issuing security updates but they don't change the version number any longer or give new features.
By the time Apple stops issuing security updates for 10.6.8, that machine likely will be dead of another cause/hardware failure of some sort, most likely the graphics will go on it next.
So I foresee the two events accuring about the same time for you, I see spending more money on that old machine in new software for 10.8 etc., as a complete and utter waste.
If you purchased a used Early 2011 model or later, then I wouldn't have any objection and say go right to 10.8 if it has enough RAM.
OS X 10.4/10.5 need to upgrade, 10.6.8 ok still

Reinstalling Snow Leopard from Mountain Lion

In another thread, I was getting help with cloning and told to purchase a new external drive to do so. When I went to the Apple store today to purchase an external drive, he actually talked me out of it. I told him my goal was that if I tried Mountain Lion and had problems, I wanted to be able to revert back to Snow Leopard.
He said that, since I have the Snow Leopard Install DVD, that if I didn't like Mountain Lion, I could restore my system by:
1. In Mountain Lion, use the disc utility to erase the drive
2. Do a fresh install of Snow Leopard back on to my system
3. Re-attach the drive I use for Time Machine and install my files from that.
Does that sound correct as an easy way to restore my system from Mountain Lion to Snow Leopard?

Downgrade Lion/Mountain 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.

Mountain Lion/Mavericks 'breaks' wifi base station - Snow Leopard works fine

Greetings all,
(Tried this in the OSx forum with no answers, so I figured I'd try the MacMini community and this one.)
I've been reading my way toward blindness through countless threads, here and elsewhere, from countless people, having problem with Mountain Lion and Wi-Fi these last few days, but some are using Airport, some are using third-party Wi-Fi routers, some aren't really specifying what they're using, so I thought I'd be as specific as possible about my situation - and add the fact that everything is still working fine if I boot into a cloned backup using Snow Leopard.

So here's the situation. I have a Intel Mac Mini which I use as a Wi-Fi base station for a Intel PowerBook Pro and an iPod 5. The Mini has been running Snow Leopard, and the PowerBook had been upgraded to Mountain Lion a few months ago. Things were still working fine at that point - the PowerBook's shift from SL to ML didn't affect its connectivity as a 'receiver' at all. About a week ago however, I finally upgraded the Mini to Mountain Lion as well (so that I could install the current version of Adobe Lightroom) and lost my Wi-Fi Internet access.
When I turn Wi-Fi on at the PowerBook, the Mini's network is visible, and I get the solid Wi-Fi fan showing a full connection, but I cannot access the Internet (indicated by the exclaimation point inside the fan for the first few seconds). The same is true on the iPod - I get the checkmark showing that I'm connected, but when I try to access any Internet services will get a pop-up box telling me that the Internet is not connected.
After going through pages and pages and pages of people struggling with similar issues on sites like this, and following suggestions like deleting my preference files, repairing permissions, zapping PRAM, creating new locations, changing IP addresses etc. I got no further. But since I had cloned my hard drive just before the upgrade from Snow Leopard to Mountain Lion (thank you SuperDuper), I can reboot into Snow Leopard, and everything still works fine. With that advantage, I copied and re-created EVERY SINGLE preference in the system preferences for Network and Internet sharing* from the Snow Leopard into the Mountain Lion system. (I even went so far as to create a network in Mountain Lion's prefs. with WEP encryption instead of the newer WPA just in case that would make any difference at all.) But even with identical settings on the Mini regardless of booting into Snow Leopard or Mountain Lion, Mountain Lion remains the same - no problem connecting with the network, but complete inability to access the Internet. A few days ago, hoping against hope that an upgrade to Mavericks might reset things into some sort of working mode, I tried that - but no better result.
(*) I note that the wifi heading in the preference panes has changed from "AirPort" in Snow Leopard to "WiFI" in Mountain Lion and Mavericks, but I'm assuming that's just a change Apple made in its terminology to avoid confusion with the external AirPort options.
I would appreciate any suggestions any of you could give. And I would ask that you specify whether any suggested changes are to be made on the originating Wi-Fi station (in this case the Mini), or the receiver (in this case the MacBook). Many of the threads I've read to date can be confusing simply because they're not specifying on which machine any suggested changes need to be made, and while I'm sure there's nothing that needs to be changed at the MacBook, please specify if I'm wrong.
Thanks again,

Greetings all,
(Tried this in the OSx forum with no answers, so I figured I'd try the MacMini community and this one.)

Dual Harddrives Mountain Lion

Hi, how do I register my copy of mountain lion? I changed harddrives and I've been having permission problems with the harddrive that are stemming from the OS not being verified on my new harddrive. I purchased Mountain Lion from the App store on my old harddrive and Carbon Copy Cloned the old drive onto the new one (the clean install is annoying, because I have 2 internal harddrives, and setting up locations confuses me). Any help with how to show my computer/ apple that I didn't torrent my copy of Mountain Lion would be much appreciated. I still have the old harddrive in an external enclosure (the one that I originally downloaded it onto if that helps). Thank you
Or if someone could list the neccessary steps in order to do a clean install as well as link the applications on the secondary drive.

Hey, thanks for the quick reply. I had the same problems when I was using Snow Leopard. The problem is that my user account is not allowed to read/write my harddrives, but not all the time. I can't seem to pin point what I'm doing that is causing it, and thus it appears that the permissions for each drive will randomly switch between my account being read only and read/write. When I was on snow leopard I had a similar issue which occured whenever I opened itunes (only itunes, no clue why). Neither of my Harddrives get a lock on them, just the access privelages are changed. Also in disk utility, the repair permissions option isn't clickable

OS X Recovery Disk Assistant v1.0 to reinstall OS X Mountain lion

I have used the OS X Recovery Disk Assistant v1.0 to reinstall OS X Mountain lion on my Imac and i have used an external hard drive, but while rebooting, i didn't click on the recovery HD and now the external hard drive isn't visible. Can anyone help?

You are welcome. If you get all/some of your data back, I suggest you start backing up the external drive. If you can't do that using Time Machine, you can try one of the cloning programs below:
Clone - Carbon Copy Cloner
Clone – Data Backup
Clone – Deja Vu
Clone - SuperDuper
