Macbook Pro - Boot from External Hard Drive
My Macbook Pro originally came with 10.7 Lion, is currently on 10.8 ML, and will soon be upgraded to 10.9 Mavericks. I have an older 10.6 Snow Leopard Clone. Can a Mac boot to an older version of OS X than what came preinstalled when it was new?
No, generally it cannot. If your model came with Lion originally, then it probably cannot boot from a retail Snow Leopard system, but it's possible it might from 10.6.8. All you can do is try, but you'll need an older model so you can install and update Snow Leopard on the external drive.

Why wont my macbook pro boot with external hard drives connected?
After two years of uninterrupted success running my MBP with five external hard drives attached (two USB, two eSATA with LaCie Expresscard 34, one FireWire 800), my MacBook Pro with Mountain Lion 10.8.2 installed will not boot with the drives attached. Starting up with the option key depressed does not work. Anyone have insight? This didn't happen until I upgraded to 10.8.2, so is there a bug fix needed in that update?
Update, I reset the PRAM (i think) and now the chime is back as I start up... small win but thats all it does.
So I decided to dload a copy of Lion and burn to a disc, then try and boot from there. When i boot holding option and select the dvd it sounds like something is happening, contstant turning or reading of the disk, but nothing is happening on screen, just my old friend the apple logo and his mate the spinning wheel. Starting to concede now, just hoping to get my data back, its mostly photos and some files i cant duplicate.
I am going to purchase Mountain lion on my current apple ID using a friends macbook and try and reinstall from there. Although i never had Mountain Lion installed in the first place (just lion) there isnt an option to buy lion on the app store (i dont think) This is prob my last spin of the dice i think before handing it in, unless anyone on here has some ideas.... -
Booting from external hard drive on intel-based MacBook Pro
Good day everyone. I know similar questions were raised in this community, but I still have some questions.
I have MacBook Pro(late 2011) with OS X 10.7.5 and external hard drive with Ubuntu 13.04, from wich i can boot succefully on my PC. But MacBook Pro will not boot from my external drive, no matter which key/combination i use during restart.
After googling I found some answers to my initial question, how to boot from external hard drive

As I understand I need to format my external hard drive into GUID partition type and this will be enough to be able to boot from it on my mac?
With this new partition type, will I be able to install ubuntu again on my external drive?
Does GUID partition type supports NTFS, ext4 and FAT32, linux swap?(I use ntfs for big files, ext4 as partition for ubuntu and fat32, because i use windows, linux and osx)
Will I be able to boot from my pc from my external drive with this new partition type?
What are downsides, if any, to GPT?
here is info on my e-driveLowLuster wrote:
The only OS that will boot from an external drive is Mac OS X or maybe Linux. For OS X to be installed on any drive it need to be formatted Mac OS Extended and have GUID partition table.
As for Linux I'm not that familiar with it but again for a Mac to boot it need an EFI partition on the drive and I don't think that is possible with NTFS or FAT32 let alone the native Linux format.
Went to wiki to learn more on efi but found artice on uefi.
Operating system loaders are a class of the UEFI applications. As such, they are stored as files on a file system that can be accessed by the firmware, called EFI System partition (ESP). Supported file systems include FAT32, FAT16 and FAT12, and supported partition table scheme is GPT only. UEFI does not rely on a boot sector, although ESP provides space for it as part of the backwards compatibility.[26]
Here is FAQ on official uefi website.
Can UEFI Secure Boot be adopted and implemented by a variety of operating systems?
UEFI specifications are platform-independent, supporting multiple platforms and architectures. In addition, UEFI specifications are designed to promote cross-functionality, as well as to support broad adoption across multiple operating systems, including Windows as well as Linux-based operating systems. The specifications are robust and can potentially complement—or even advance—other distributions, such as Linux-based distributions.
And here is wiki article on GPT expaining OS support.
It is obvious both uefi and GPT are ok with Linux and file systems such as FAT32, ext4 and NTFS.
I guess there is no much difference(or is that the same thing?) between uefi and efi used in Macs.
In your answer to Stark Industries you said that mac can boot linux from external hard drive, well this is not the info i got of official website and it is still my question, because your answer is very inconclusive and your info is partially incorrect -
how to transfer data from macbook pro to an external hard drive, im using (WD 1TB 3.0) ???. I cannot copy anything from my mac to it not a single file.
ok - since you'll be sharing it with a PC - connect it to your windows pc - then format from there - instead of NTFS format - choose exFAT.
or, you can read the link below on how to do it in dos mode.

once you've formatted it - you can now use it in both your macbook and windows computer. -
Trying to copy ANY file from my MacBook Pro to an external hard drive spins for 45 minutes then fails. I hate this computer and WISH I never would have wasted my money. Any ideas? WD My Passport 2TB Drive, had to buy a program to make the POS read files. Copies that would take seconds from a Windows based machine never complete. I have to close the transfer or shut off the machine half the time. Worst computer I have EVER owned, crashes non-stop, constantly freezes, and seems like EVERY operation is more complicated with this thing. Literally, my 1997 Compaq was FAR MORE reliable and user friendly.
This is one of the messages I keep getting; The Finder can’t complete the operation because some data in -- File Whatever -- can’t be read or written.(Error code -36)
I have copied things to the hard drive in the past, but it has always been incredibly slow, and now just seems to freeze and fail -
I have stored everything on my Macbook pro in a external hard drive (Time Machine) Now that we have "wiped the machine" I am told I can start it over and load ontent--apps, docs, etc from the hard drive, just plug it in, find the time machine and what? I need to know what to highligh, what to click on.
hirogliffix,
take a look at this Apple page — in particular, the “Restoring data from Time Machine backups” section and its “Restoring your entire system from a backup” subsection. -
How do i back up my macbook pro to an external hard drive?
how do i back up my macbook pro to an external hard drive?
schmunzelmonster, greetings; Your suggestion is a good one. CCC does create a boot drive which as you point out can be most useful at times. Time Machine does not have that capability but it retains a history of activities and transactions that CCC does not. CCC only retains information as of the last update.
Neither individually is the 'perfect' backup solution individually, but if both are utilized it becomes that. There is no harm in backup redundancy.
My only complaint about CCC is that is is very slow in performing updates compared with Time Machine. Just a nit on my part.
Ciao. -
Every time I try to back up my Macbook Pro with an external hard drive using Time Machine, I receive the error of "the disk does not have enough space". I have a 500GB external hard drive and only 120GB Macbook. It worked fine before the latest Maverick's update. Any help would be greatly appreciated.
My guess would be it has created an entirely new backup of your drive when you upgraded to Mavericks.
See Here: http://pondini.org/TM/1.html
And here: http://pondini.org/TM/9.html
Peruse the whole site. There is a lot of information there. -
just baked up my macbook pro to an external hard drive. my computer died on me and i plugged it in and rebooted it ,started time machine and finished backing up but. just wondering if thats good or should i delete and restart
I wouldn't trust that backup.
Make sure the system is connected to AC and Do Over. -
How can I backup my MacBook Pro to an external hard drive
How can I backup my MacBook Pro to an external hard drive?
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
used to manage backups and to restore backups. Time Machine
requires a backup drive that is at least twice the capacity of the
drive being backed up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Although you can buy a complete external drive system, you can also put one together if you are so inclined. It's relatively easy and only requires a Phillips head screwdriver (typically.) You can purchase hard drives separately. This gives you an opportunity to shop for the best prices on a hard drive of your choice. Reliable brands include Seagate, Hitachi, Western Digital, Toshiba, and Fujitsu. You can find reviews and benchmarks on many drives at Storage Review.
Enclosures for FireWire and USB are readily available. You can find only FireWire enclosures, only USB enclosures, and enclosures that feature multiple ports. I would stress getting enclosures that use the Oxford chipsets especially for Firewire drives (911, 921, 922, for example.) You can find enclosures at places such as;
1. Cool Drives
2. OWC
3. WiebeTech
4. Firewire Direct
5. California Drives
6. NewEgg
All you need do is remove a case cover, mount the hard drive in the enclosure and connect the cables, then re-attach the case cover. Usually the only tool required is a small or medium Phillips screwdriver. -

Why won't my iMac 27" boot from external hard drive?
I have a new 27in Intel i5 dual core 3.6GHz iMac. It works wonderfully.
My question is this. I have a Pleides Ice Cube external hard drive with a USB 2.0/Firewire enclosure with a 500GB hard drive. I used diskutility to format the hard drive as a GUID Partition Table. I then used SuperDuper to clone the iMac OS 10.6.7 and Apps over to it.
I can select the external drive in System Preferences/Startup Disk to boot from, but when booting the iMac gets as far as the white screen then just stops loading.
I have tried both the USB connection and the Firewire connection (with a Firewire 800 to 400 cable).
I have run Disk Utility and repaired the disk and the preferences.
I have used Disk Warrior to rebuild the directory as well, but the iMac will not boot from the drive.
It does boot from the original DVD's and its own hard drive.
My old 24" iMac had no trouble booting from this hard drive or any of the others I have collected over the years, so I am reluctant to think it is the external drive. It is something to do with this particular processor Snow Leopard and external drives.It sounds like something in the SuperDuper clone might not have copied well. To get the full answer on that I would check with Apple or SuperDuper to see if they support each other.
As a quick test, if you restart and immediately press and hold "option" on your keyboard do you see your external HD as an option to boot from? If so, click it and see if the boot runs any differently, but if you don't see it at all that could show that the problem is more deep rooted.
Personally, if looking in to either of those didn't give me any other info to go on, I would reformat and start the clone again. BTW, do you know for sure GUID Partition is the format you'd want to do this on? Generally macs use "Mac OS Extended" and some external HDs can use "FAT32" (if you want them to work well with Windows)
Hope that gives a little direction

How do I transfer everything from my 2006 macbook pro to an external hard drive?
I am selling my Macbook Pro 2006 to upgrade. I want to clear all info off my computer. First, I want to move all info to an external hard drive. Is this possible? I recall that there is a way to move info form mac to mac by hitting alt A? Would this work for tranfer to the external drive?
No, here's what you want to do:
Clone using Restore Option of Disk Utility
1. Open Disk Utility in the Utilities folder.
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.
Destination means the external backup drive. Source means the internal startup drive.
This process will first erase the external drive. The result is a bootable backup on the external drive. -
I can't access any of my files, photos, anything form my external hard drive... It worked before now when I plug it in the light comes on, but it doesn't even show up as an external drive, so I can't access anything, I'm worried I have lost everything...
Huge mistake was only having ONE copy of your data OFF computer,
most people do it, and its just horrible and the typical reason for serious data loss.
Likely you have a very common failure (extremely common actually) called SATA bridge card failure, which would be "good" news,
read about same here:
Your dead external hard drive is likely fine! Great hope for your 'faulty' external HD
Never again let yourself have LESS than 2 copies of your important data off-computer, ever
1. verify the external HD doesnt show up on another Mac
if same, you have about a 8 in 10 chance its SATA card failure.......... easy to fix.
The great news at the end of the tunnel of an apparently failed or failing external hard drive.
When checked on another computer, and with no need for spending money on data extraction expertise or software, the very likely case is that your external USB or thunderbolt HD is in fact fine, and merely the card interface, or SATA bridge card has failed or is failing. Keeping a HD dock around handy, or cheaper still a $20 hard drive enclosure or a SATA to USB connector can be a real life saver in getting your drive back to use, when the drive itself is fine, and merely its interface card has gone bad.
The SATA bridge card inside a USB external HD has a very high failure rate in general
Typical SATA bridge cards as seen inside a 3.5" external HD with power input (#1), and 2.5" SATA cards (#3, #4, #5)
What are the realistic odds your HD is perfectly fine?
There are no hard facts whatsoever, especially since so many people discard their assumed “dead/faulty” hard drives, but a good educated conclusion from years of examining and seeing this issue is that for hard drives made since 2010, and not dropped or generally abused, is that a minimum of 50% conservatively are perfectly fine! I personally estimate however that it likely approaches 60%+.
Considering how many external hard drives ‘fail’ (rather the SATA bridge more than half the time) each day, that is a very high number of perfectly fine HD that are tossed!
This is especially common with 3.5” desktop HD that are connected 24/7 with power and see a lot of data transfer. People wrongly conclude that “X” mfg. just made a defective drive, when in fact their 3.5” drives inside the plastic enclosure is 100% fine. I have personally seen well over 200 of these dead SATA cards and additionally seen 3 fail within a one hour span of doing a large data copies.
One of the very reason pros use bare HD as inserted into HD docks is not just the saving of space and the need for endless USB cables, but the elimination of the need for this high failure-rate part.
While the shapes and sizes vary somewhat on SATA bridge cards, they all serve the same purpose and have likewise failure rates
What exactly is the SATA bridge card in your external HD?
In the middle to late of 2009, most all external hard drives both in 2.5” and 3.5” reached the shelves in SATA III. These small SATA cards or "bridges" are used to translate between the hard drives’ interfaces and the enclosures' external ports (USB, Thunderbolt, Firewire). Additionally these small bridges not only transfer power but also of course the data. Unfortunately these SATA bridge cards have a very high failure rate as they are burdened with shuffle power and data.
Literally these little unreliable and fragile cards are the power conduits and the nervous system for all external HD data transfer.
SATA card as found inside a typical USB external hard drive
The assumption that the hard drive is bad when its not!
Countless 1000s of good external hard drives are thrown away each year because the owner thought the HD was bad when it fact it was the SATA bridge card which had failed. This card is removed in a matter of mere second once an external USB HD is cracked open from its plastic casing to reveal the bare HD and the attached SATA card which attaches between the HD and the USB cable.
To complicate this problem, even many computer professionals do not know that there is a very easy solution to the “failing or dead HD” issue since the hard drive itself is very likely just fine. Its astonishing that so many highly educated computer repair persons are unaware of this high-failure part, but this is mostly due to the fact that they do not juggle 100s of hard drives and know that of the iceberg that is a “external hard drive failure”, the mostly unseen majority are not a HD failure at all, but a bridge card failure.
To add to this great misunderstanding is the fact that people assume that "likewise symptoms seen on an external HD are the same as seen on an internal HD, therefore also the external HD must be bad". This is a compositional fallacy of logic. Since internal HD do not have a SATA bridge interface, to conclude similar symptoms "indicate the same failure" is misplaced and incorrect.
This is all not to say that HD do not fail, they do indeed, and I have seen many 100s of dead and failing hard drives. Hard drives even under ideal conditions have a life expectancy of around 4-8 years due to ferromagnetic depolarization from entropy. But of the mountain of symptoms that are seen as “hard drive failures” in comments, posts, and hearsay, half or more of these are not a HD failure at all.
Once your rescued hard drive is removed from the bad SATA card
You have several options, but the purchase of a $20 HD enclosure is one option, another is having a HD dock, however this eliminates the former portability in a 2.5" small HD.
Remember that 3.5” HD require power, which means you need either a HD dock, or a powered SATA card kit as seen at top left in the picture below. 2.5” HD get power from the USB port itself.
Just remember that the serious downside to the low cost external HD enclosures is THEY TOO contain these SATA cards, and what is worse the cheap ones will fail, often, much quicker than the original factory one did! In which case it is recommended you buy a quality HD USB enclosure

i have an external hard disk but whenever i tried to transfer any file or data from macbook to this ext.disk its failed before that i used to have another hard drive with same problem ,then i thought may be this hard drive is not support mac then i bought a new one which supports mac but still i have same problem what should i do ?
Ok.
Go into Disk Utility, and make sure you select your external hard drive.
There should be 4 tabs, one being erase. I have taken a screenshot to show you what it should be set to (obviously name it what you like), and set the format to Mac OSX Extended (Journaled) as per the example below & after double checking your in the right drive, you can hit erase. And you're done! *hopefully*
