Mountain Lion is missing, after installing an external hard drive and Carbon Copy Clone.
I have a mid-2007 desktop iMac Model MA877LL, 2.4 ghz/1gb/320gb, with 4 GB memory, upgraded to Mountain Lion 9/7/2012 at an Apple store (now 10.8.5). I just installed a new external hard drive Fantom Drive 1T G-Force Mega Disk Firewire 800, then installed Carbon Copy Clone successfully. However, I could not get the clone to boot from the backup volume. Mountain Lion showed in both Macintosh HD and External Hard Drive at that point. After working through many steps with CCC, trying to get it to boot, the final suggestion was to try installing Mountain Lion onto the backup disk via the Mac App Store Installer. As my Mountain Lion was installed at an Apple store, there's no record of it on line and I can't find an installer, although I've been doing updates as they're issued. Per article, "OS X: Installing OS X on an external volume", I erased and reformatted the storage device. Now, checking my Macintosh HD, Mountain Lion is gone. How do I get it back?

Are you saying that your internal HD doesn't have an operating system on it either, meaning you can't boot your iMac at all? Or that the external was also named "Macintosh HD" in which case, having been erased and reformatted (hopefully with a GUID partition table), you'll need to clone your internal to it once again.

Best External Hard Drive for Carbon Copy Cloner?
I'm about to do a clean install of Leopard on my *Mac Pro* but I want to back up/clone my current system (10.4.11) to an *external hard drive* first. Based on the recommendations of similar users (Logic Studio) -- a clean install is preferable to an upgrade from Tiger to Leopard. I plan to use *Carbon Copy Cloner* to clone my current system but am unclear as to whether I can use an *external USB drive* versus an external Firewire drive.
Some people claim that firewire is much faster and more reliable for transferring/backing up data, and more importantly, that it's the only type of external hard drive one can boot from -- but I'm not sure that's true for these Intel-based Macs.
Also, I currently use an *Apogee Ensemble* audio interface which does not like sharing the firewire bus with other peripherals. I've also heard references to a external hard drive chipset called 911+ as being important but I think this may only be in regard to firewire.
Bottom line, _can I use an external USB drive with Carbon Copy Cloner on an Intel-based Mac?_
I'm looking for something around 500 Gigs that can sit on my desk with a minimal footprint. I'd like to partition it into three volumes -- the first for the Tiger clone; the second for weekly Leopard back-up; and the third for sound library storage. I'll likely need to access the third volume in realtime from *Logic Pro 8* (audio application) so the HD should be pretty fast. Recommendations?So Kappy & Hatter...
Allow me to spell this out in practical terms. I'm installing Logic Pro, an audio production application. The consensus is that best results are achieved by installing the application on the internal system drive in bay #1 on the Mac Pro.
Most professional users of Logic Pro recommend a second internal drive in bay #2 solely for audio recording even though the app runs on the drive in bay #1. The drive in bay #2 is often a Raptor because of the 10,000 rpm spin rate, beneficial for the recording process.
For sound libraries with large audio samples/loops, often streamed to the app -- a third drive is recommended to store the sound library. It can be internal or external. Many people use external drives for this function on a firewire 800 bus. The emphasis for this drive would be to read quickly and stream the samples quickly. I would assume that a 32MB buffer cache versus 16MB would be beneficial. I was looking for hi-speed if I went the external route -- hence my foray into the realm of eSATA buses, but perhaps I should just get an internal drive for this as I do have drive bays available in the Mac Pro.
Can you recommend drive spex for this task or a particular hard drive for this task of storing and streaming the sound library? -
OS is Mountain Lion, upgraded no problems, used an external Hard drive for my time machine, now my iPhoto will not show any of my photo's or ay new ones I import! Help please!!
Do you get this window when you hold down the Command+Option keys and launch iPhoto?

Can someone please provide instructions on how to import an iPhoto library from an old Mac to a new Mac without getting a bunch of duplicates? I tried transferring my pictures using an external hard drive and then copying it to the Pictures folder on my new Mac. I ended up getting a bunch of duplicates. My old Mac has an older version of iPhoto while the new Mac has iPhoto '11. Is that the cause of the problem? Please advise. Thanks.
Simply copy the iPhoto Library from the Pictures Folder on the old Machine to the Pictures Folder on the new Machine.
Then launch iPhoto. That's it.
This moves photos, events, albums, books, keywords, slideshows and everything else.

Safari crashes after installing iomega external hard drive
I've just installed the iomega desktop external hard drive with firewire and usb 2.0. I'm presently connected to my computer by the USB port. Everytime I go to access Safari or Mail they quit on me after a few seconds. I've now disconnected the drive from my computer and it's fine. I did to a Disk Utility repair after the installation but that didn't help. Is there something I neglected to do? Is there a problem between Mac and Iomega? Should I use the firewire instead?

I have Lion on an external hard-drive and I want to install it on the internal disk
I have Lion on an external hard-drive and I want to install it on the internal disk. How can I proceed?
I recently completed a clean install of Lion on an internal SSD. After wiping it clean, I used a thumb drive with SL on it to boot and then another thumb drive with Lion on it. It worked just fine. The only thing to be aware of is that if you use the thumb to install Lion from... it will not install a recovery partition and you'll have to use the thumb in the future.
That's what I wanted anyway so it's working out just fine. Good luck.
I should add... I used the SL thumb to actually boot from and used Disk Utlities to wipe the internal SSD. It does work and there are Apple posts that can guide you through the thumb drive process. I used copycat to create both the SL boot and Lion. -

I have some applications that are windows only. I want to install windows 7 on my external hard drive and boot to it when I need to use my windows applications. Is this possible with a mac and, if so, how can I do that? I have a 64-bit Macbook Pro running Mountain Lion.

i see that i have a problem after installing my new hard drive on my macbook pro mid 2009 version. I put a new hard drive, with all of my information from my old drive installed on it, into the computer. but now have the blinking question mark folder. I see that it means that it isn't reading the new hard drive.
did i miss a step between transferring all of my information from my old hard drive to the new hard drive and installing the new hard drive into the computer. I believe that i installed properly. it was quite easy.
thanks for your helpIt means there is no bootable system on the drive. If you still have access to the old drive, then I suggest you boot from it then clone it to the new internal drive. Use OPTION boot to boot from the Recovery HD on the old drive:
Boot to the Recovery HD:
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.
1. Select Disk Utility from the main menu then press the Continue
button.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag it
to the Destination entry field.
5. Select the source volume from the left side list and drag it to
the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Source means the external old drive. Destination means the new internal drive. -
I have just downloaded iPhoto from the app store. The photo library from my old laptop was backed up on an external hard drive and I retrieved the photos from there. Now when I open the photos on my new Mac Book Pro, they are small - am I missing something?
I am using 10.8.2 Mountain Lion btwI dragged the Photo library icon from the backup drive on to iPhoto on the laptop
That means you imported one Library to another.
Never import one Library to another. Every version and thumbnail is imported like a distinct photo, you lose all your Albums, Keywords etc., the link between Original and Previews is destroyed, the non-destructive editing feature is ruined and so on. In summary: it's mess.
So the reason you're seeing small photos is because you're seeing the iPhoto thumbnails from the back up library.
So, what to do?
Do you still have the back up? If so, trash this bunged up library and restore from the back up again. HOw to restore will depend entirely on how you made the back up, but no version of restoring includes importing the library.

Why will Photoshop CS4 not open after loading to new iMac from an external hard drive and I get this message: Licensing for this product has stopped working:error code: 150:30
A Photoshop installation is tied to the machine it was installed on. Moving it to or from a hard drive breaks the licensing.
The answer is easy: Reinstall CS4 from your disc. and apply all updates.

My Mac Mini does not boot, after backing the enire system onto an external drive with Carbon Copy Clone. I had switched the start-up disk back to the original of course. Now all I see is the Apple logo. What should I do? Thanks in advance.
Try disconnecting any external devices, especially hard drives
and try rebooting.
If that doesn't help, then :
If you are running Lion, boot to the Recovery HD and run a
Repair Disk on the OSX partition.
If Snow Leopard, boot to the installl DVD and run Repair Disk.
Also, you may want to bookmark this:

Lost some permissions after synchronizing with external hard drive
I bought a LaCie external hard drive so I could back up my files in preparation for upgrading from Tiger to Snow Leopard. Everything was working fine for a while. This is my first experience using an external hard drive and performing back ups. The external drive can perform two functions; back ups and synchronization. I went in and made some changes to the settings for back up and synchronization because I was getting error messages after performing back ups. Evidently, I changed some things I probably should not have.
Prior to the changes I made to the back up/synchronization settings, I was using a folder of pictures as my screen saver. One day I noticed that I can no longer do that, my screen saver keeps defaulting to "Flurry". Even though I go in and change it, the changes I make do not take. I also noticed that in my address book, the pictures I had placed there for different contacts are no longer there and I can no longer add them. One more thing I noticed is that each time I open iTunes, the SLA is displayed and even though I agree to it, it show up every time I open iTunes.
I assume that my "permissions" (for lack of knowledge of the correct term) were somehow compromised when I made the changes to my back up/synchronization settings. Can anyone tell me how I get control back for these functions which I used to be able to perform?Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Tiger Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then Safe Boot , (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it finishes.
The usual reason why updates fail or mess things up, or things don't load/run, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
Some people get away without Repairing Permissions for years, some for only days.
If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates again, or even do an A&I if you have enough free disk space.

The combo update for Intel-based Macs...

Repair Permissions before & after re-install, then reboot again each time.
If all the above fails, then it appears to be time for a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...

That way I can wait a week or so, check the forums for potential problems, and get Permissions & such in order before installing. -
Lion External Hard Drive (and flash drive) problem
I recently installed Mac OS X Lion on my Macbook Pro. I plugged in my external hard drive and my computer recognized the HD and even let me access files on it. However, when I tried to copy a movie onto it, it gave me an error: "The operation can’t be completed because an unexpected error occurred (error code -8003)." I decided to try a different file, the same thing happenned. I tried a USB flash drive and the same thing happenned. I checked the permissions for them and it says "you can read and write" so everything is fine there. If it helps the HD is formatted as "MS-DOS (FAT32)" and the USB stick is "MS-DOS (FAT16)".
I don't really know what to do because I have never had this problem on the same computer with Snow Leopard in the past (the only time I did was when the file was too big to copy onto it because of the formatting or something but it definetely isn't the case now).
PLEASE HELP!There might be a bug in the driver of the FAT-32 files systems. That is the likely cause, resolution, go for any free FAT-32 filesystem driver for mac. There is very less security feaures in FAT-32, and I am sure that the security messsagae is a red herring.
What you can possibly do is a unmount, and then a remount, manually.
