I am upgrading from Tiger to Snow Leopard. I keep getting an error when I try to load the Mac Os x update combined. It says that it was corrupted during download. Have try loading from Apple website V10.6.7 upgrade combined but it still won't do it?

I have an Intel Desktop iMac and I am upgrading from Tiger to Snow Leopard. I keep getting an error when it tries to load the Mac OS X update combined. It says that it was corrupted during download. Have try loading from Apple website Mac OS X V10.6.7 upgrade combined but it still won't do it? Any other suggestions. The printer is not working either - I am not sure if they are connected. Everything else is fine.

Please excuse, but I have to ask an obvious question: Did you already update using the Snow Leopard Retail install DVD? (You must do this first; 10.6.7 is just an update if you already have 10.6.) Are you, then, trying to update from whatever version was on the install DVD to 10.6.7?
Otherwise, I'd keep trying. The 10.6.7 Combo is a huge update.

I have a hdd from late 2009 that I upgraded from leopard to snow leopard to lion to mountain lion. I want to upgrade the hdd to ssd. Do I need to buy a new copy of mountain lion to install on the ssd? If not, then what is the procedure to transfer?

I have a hdd from a late 2009 mbp. I upgraded from leopard to snow leopard to lion to mountain lion. Now I want to upgrade to a ssd. Do I need to purchase a new copy of mountain lion to go on my new ssd? If I don't, then what is the procedure to transfer mountain lion with my 4 user accounts onto the new ssd from the hdd?
I'm confused on if I can use the recovery hd on a thumb drive to install mountain lion on my ssd. Will it be pheasible with so many OS X upgrades? And then how do I get my user accounts onto the ssd from the hdd. Do I use migration assistant? Do I need to make a time machine backup first? Should I use something called Carbon Clone or something like that?
Thanks for reading

If you have a cable that connects and external HDD to the MBP, it will do. If it is something like this, an enclosure will not be needed for the swap:
An enclosure allows you to use your old HDD for storage or backup purposes. The cable will not.
Here are instructions as to how the swap can be performed using DISK UTITY. Substitute You cable for the enclosure in same:
INSTALLING A NEW HDD IN A MBP
1. Make certain that you have backed up all of your important data.
2. You will need a HDD enclosure. One with a USB connection will do. A 9 pin Firewire is better.
3. Install your new drive in the enclosure and connect it to your MBP.
4. Open DISK UTILITY>ERASE. From the left hand column drag the new drive into the 'Name' field. Make sure that the format is 'Mac OS Extended (Journaled)'. Click on the 'Erase' button.
5. Click on the 'Restore' button (on top). Drag the old drive into the 'Source' field and the new drive into the 'Destination' field. Click on the 'Restore' button on the bottom right hand corner.
Depending upon the amount of data you are transferring, this may take a couple hours or more. A Firewire will speed up the transfer. This will result in both drives having identical information on them.
6. After the data transfer has completed, you may swap the drives. Start the MBP and you have finished the installation. The initial boot may take a bit longer than you are accustomed to, but that is normal.
7. When you are satisfied that the new hard drive if functioning properly, you can erase the old drive and use it for any needs that you may have.
If there is any confusion on your part, post back.
Ciao.

HT1338 i upgraded from leopard to snow leopard ( i know i am really behind) but now iTunes won't recognize my iPhone. and the updates keep crashing when they are trying to install...help!

I upgraded from leopard to snow leopard. now iTunes won't recognize my iphone, and the upgrading the software keeps crashing.. help!!

Mountain Lion is OS X 10.8
10.6 was called Snow Leopard.
To use iTunes 10.7 the following is required:
Macintosh System Requirements
Mac computer with an Intel Core processor and 512MB of RAM
OS X version 10.6.8 or later
Safari 4.0.3 or later
400MB of available disk space
Broadband Internet connection to use the iTunes Store
Do you use iTunes Match?
That way all of your songs would be matched with the master song on the iTunes servers independently of iTunes on your Mac or PC...
Look here for further information: http://www.apple.com/itunes/itunes-match/

The only observations are that the backup drive is deemed too small and the quite long list of diagnostic reports dated between Jan 18, 2015 (which I believe is the day I upgraded to Yosemite) & today the latest Yosemite update was installed on Jan 28, 2015
Any further assistance will be appreciated

I've read similar questions and answers, but I am still terrified to upgrade from leopard to snow leopard. The only reason I want to is because I received an iPad which requires an updated system. I have an external hard drive. I have the disks to upgrade

I've read similar questions and have studied the answers, but I am still terrified to upgrade from leopard to snow leopard on my macbook pro. The only reason for doing it is in order to sync my macbook pro with my iPad. I do have an external drive which automatically backs up every hour. BUT.......I am techno-ignorant as well as techno-paranoid. I have the disks to update to snow leopard but knowing doing so may likely change/alter/lose/obliterate my current set-up, it actually makes me feel sick to think of it.
Years ago when updating via Apple Protection Plan tech support, my screen actually went blank, everything gone! The tech told me not to worry, that "we" would be able to restore things, but several hours later I was still looking at a primitive looking screen that wasn't anything like what I had before. His language was too technical, in that there was an assumption I understood things I had zero understanding of. Example: partition my external drive.
Anyway, living hundreds of miles from an Apple service provider, and no Apple techs in my community, I had to wait for a trip to an Apple Store where one of the wonderful guys at the genius bar spent a ton of time getting things back to normal and actually explaining it enough that I had a vague understanding.
So now I am in the predicament again and won't know what to do after installing the new disks and finding a likely mess or absence of documents etc. on my computer. I don't know how to access the external drive, and even if I did I wouldn't know how to move stuff from that to my computer.
Anyone have any suggestions?

I'm in the same boat as you, I've used Mac's since day one and neglected my Windows education and now it has come to haunt me as I have to learn it like a school kid.
Nearly 99% of all businesses and nearly 95% of everyone use Windows, Steve Jobs declared "The desktop wars are over, Microsoft won" a long time ago.
By 2015 tablets are going to be selling to consumers more than traditional computers, your living proof, you got a iPad.
Apple has already discontinued the Xserver, the Xraid, the MacBooks and the 17" Macbook Pro.
Apple has introduced BootCamp in OS X 10.6 and up, this allows a partition and drivers so one can install Windows on a Mac.
https://www.apple.com/support/bootcamp/
Why do you think they named it "BootCamp"
You can't run a older OS X version longterm like you have with 10.5 anymore, Mac's are being targeted for attacks and older OS X versions are dropped for security updates.
In fact your Mac might still be part of the 750,000 Mac strong Flashback botnet or infected.
https://en.wikipedia.org/wiki/Trojan_BackDoor.Flashback
http://arstechnica.com/apple/2012/04/how-to-check-forand-get-rid-ofa-mac-flashba ck-infection/
See here, Apple has no security updates for 10.5 users and soon 10.6 is going to be ignored next.
https://support.apple.com/kb/ht1222
1-1.5 years is the OS X upgrade cycle. Change everytime like it or not.
So I'm thinking about your long term future and how you obviously don't like change, need local assistance like it appears you first claimed.
So buy a new Mac and upgrade your OS X version whenever Apple shows it in AppStore.
When your machine can no longer upgrade to the newest OS X version, then you've got about another 2 more years of security updates before you have to buy a new machine or risk running a insecure one.
Learn here how to go about fixing your own machine and creating backups/bootable clones this way your not having to drive several hundred miles for a software or boot drive repair. Simply reverse clone your troubles away.
Most commonly used backup methods
https://discussions.apple.com/community/notebooks/macbook_pro?view=documents
I'm of the maturity and experience that I know a Mac isn't always the best solution for everyone and even Apple doesn't provide the proper hardware, support or features for everyone. Why only store locations in high traffic ritzy areas?
Our SteveJobs fan here is under 18 years old with good eyes, he's not older like we are with bad or failing eyesight.
The new Mac's have hard to see glossy screens and the type/UI can't be scaled up easily to accomadate our older eyes, however a Windows 7 machine does allow up to 150% scale of the UI, type etc., and also there are anti-glare screen PC's and just about no more anti-glare screen Mac's.
I wrote this User tip in case you have trouble seeing the screen, at least you can scale the web browsing up
Web browsing for hard of seeing users
Apple might still be selling the anti-glare 15" non-retina on their online store, it's the "high resolution/anti-glare model"
But I can get a 17" 1080i HD anti-glare Windows 7 laptop at Sager for a lot more performance and screen size for the price than a Mac.
https://www.sagernotebook.com/index.php?page=category_browse&selected_cat=2
Screen size is important as the UI and text can be scaled up for easier reading.
Of course you do now have the option of having Windows pre-installed alongside OS X to begin your transition to the dark side.
Just call and they will accomondate, hold the option/alt key at boot time to swtich operating systems.

Windows 7 looks just as good as OS X, the secret is having a good monitor with most PC's come with don't.
Good Luck and I hope I've given you a lot to think about.

Installing from Tiger to Snow Leopard using only external monitor?

Backstory: I currently have a mac book pro which i procured from a friend after he dropped it and broke the screen. He promptly went to the apple store and bought a new one and had them swap the hard drives. After hearing this I told him he could most likely still use the old one with an external monitor even if the screen was broken. I hooked up an external monitor myself and what do you know the Tiger set up screen came up and i proceeded to set up this mac book pro for use.
The issue:
I now wish to upgrade this laptop to snow leopard or to leopard than snow leopard. The problem being when I insert the Snow Leopard disc into the drive and click install os when the computer reboots and reaches the set up screen it uses the second monitor as an extended desktop, not as a duplicate.
This means i cannot see the install screens and therefore cannot upgrade.
The F7 shortcut seems to do nothing which is sad because it worked in the initial setup of tiger.
Does anyone know a workaround so I can duplicate the screens? Why would this not be the default behavior? What is the point of extending the desktop DURING setup?
Also it seems some people are reporting problems with external monitors not being properly recognized once 10.6.3 is installed. Is there certain external monitors which avoid this?

You could boot the laptop in target mode and install the OS from another computer onto the laptop drive.

Best way to upgrade from Tiger to Snow Leopard and make a backup - help!

Hello, I have always found this discussion board the best place to go to get advice on my mac. I have an imac with Tiger OS. I want to upgrade to Snow Leopard - just bought the box set. I also have an external HD. I want to make a backup of my current system onto the hard drive in case of problems. How do I do this? Once I have done this, should I do an upgrade to SL or do a clean-install? Please advise - I have average tech abilities. Thank you!!!!!

I like KT's advice, and would add some words from a very knowledgeable mac person - John Gruber @ http://daringfireball.net/
I Believe in Murphy’s Law
Friday, 26 October 2007
Here’s how I recommend installing major new OS releases for typical users. (Atypical users would include anyone who ran developer seeds of the OS.)
First, make a complete backup of your current boot volume to an external FireWire drive using SuperDuper. (Carbon Copy Cloner would be my second choice.)
If you don’t back up daily — or at least very regularly — you’re foolish. If you don’t back up before upgrading your OS, you’re really foolish. I use SuperDuper’s “Smart Update” feature to clone my boot volume every night — the “smart” aspect is that it only changes the files that have changed since the previous backup. Before I install an upgrade, I quit every running app and run a fresh backup to create a snapshot of my boot volume. That way, if anything goes wrong, I can revert to exactly the state the system was in before installing the upgrade.
Next, boot from your external backup volume to make sure that it works. What you want to see is something that looks exactly like booting from your regular internal hard drive. Since I’ve been using SuperDuper, this has always been the case — I have never failed to successfully boot from my backup drive. Better safe than sorry, though, so I never skip this step.
Next, shut down the computer, and unplug the external backup volume. The odds of an OS installation corrupting a plugged-in FireWire volume are very small. The odds of an OS installation corrupting a FireWire volume that is not plugged in are zero.
Then boot from the installer DVD, follow the on-screen instructions, and perform a default upgrade. The default upgrade is the best choice for most users almost all the time. The reason Apple makes it the default and most obvious way to upgrade is that it’s the most convenient, and most tested upgrade path.
Update 28 Aug 2009: Starting with Snow Leopard, instead of booting from the DVD directly, you should instead pop in the installer DVD and launch the “Install Mac OS X” app on the disc. This will reboot your machine from the DVD, yes, but first it will download any necessary software updates that have come out since the disc was pressed. It’s a subtle but very nice improvement to the installer.
Arguments that there is something mysteriously dangerous or deficient about the default upgrade procedure — and that you should do a clean install instead, followed by tedious hours manually migrating software and data and preferences from your old installation — are voodoo. Apple’s installer engineers spend a ton of time making the default upgrade procedure as convenient as possible.
If you’re not a typical user; like, say, if you’ve been running pre-release developer seeds of Leopard, or if you’ve diddled with your 10.4 system software in unholy ways and really would like a factory-fresh start with 10.5, then I recommend the Archive and Install option. (That’s what I do, when upgrading from previous developer seeds.)
So, in short:
Do a complete backup clone to an external FireWire drive.
Test that the backup is indeed bootable and up to date.
Unplug the backup drive.
Pop in the installer DVD and launch the “Install Mac OS X” app.
If anything goes wrong in step 4, you have nothing to worry about, because you know that you have a complete, bootable backup.
Most people, of course, skip directly to step 4. And the odds are it’ll work out just fine for them. I say, why take a chance?

How do i upgrade from Leopard to Snow Leopard

I just recently took over managing a Mac Mini running on Leopard. I want to get it up to Mountain Lion but i need to first upgrade the OS to Snow Leopard. Is there a cheap way of doing this since i will only be upgrading so i can get it up to 10.8?
Thanks.

Upgrading to Snow Leopard, Lion, or Mountain Lion

Safe To Upgrade From Tiger To Snow Leopard?

Is it safe to upgrade a Mac from Tiger straight to Snow Leopard, therefore bypassing Leopard?
If you're running Tiger on your Mac, can you insert the Snow Leopard Install DVD and run it as normal, and the upgrade will go fine?

Hi Reuben
I think other folk have covered the potential 'gotcha' of data loss by suggesting you do a back up first. I went from Tiger to Snow Leopard directly by way of the family boxed set on both a MacBook and an older Mac Mini. Of course there is no "Time Machine" app on Tiger so back up consisted of copying all personal data to an external drive and copying it back after completing the OS upgrade by installing from the DVD. I didn't attempt to update AND keep any data, the thought of a nice, clean, new installation was irresistable.
The only issue I've had since the upgrade has been a minor niggle, which is that while I can use the 'sudo' command when logged in as the main administrator, additional users, even if they are assigned "administrator privileges", cannot use 'sudo'. Maybe I should look for answers to this elsewhere. It may not even be related to the Tiger -> Snow Leopard upgrade.
Go for it :-)

Sound volume resets at reboot since upgrade from Tiger to Snow Leopard

Hi, i upgraded my computers this week end (iMac, macbook, mini) from Tiger to Snow Leopard. All went great except one little bug : the sound volume resets at each reboot, for example on the iMac it is always at minimum after each reboot. This occurs on all 3 computers.
Do you meet the same "problem"? Do you know any solution except the clean install?
Thanks

Also, if you hold shift when clicking the volume, you can recalibrate your alert sounds level in the same way. At last, now my mac chimes at a civil level when I switch it on!
This doesn't work for me, but what it does do is play the alert volume feedback "pop" when that option is deselected in the Audio system preference & not play it when the option is selected. Thank you for that, even if it wasn't what was intended. Since I sometimes work with Macs connected to high power sound systems, it is good to know about -- you can't imagine how loud the "pop" can be until you hear it through a 20,000 watt concert PA!

Problems with Aperture after upgrading from Tiger to Snow Leopard

Help! I recently upgraded my IMac operating system from Tiger to Snow Leopard. Now, I am finding my aperture is not responding the way it used to. I cannot change the border dimensions; I can't print. Any suggestions would be appreciated. I was told by Apple Technical Support that they will not provide support for Aperture 2 and that I would have to upgrade to Aperture 3. Is this correct?

This is called a Kernel panic.
See here for possible solutions:

Did you do anything else apart from ungrading OS?
Did you add memory?
Bad or not well seated memory modules are often a cause of kernel panic

Upgraded from Tiger to Snow Leopard - now have problems with basic apps?

I have a 2007 iMac (5.1, 2007) dual core. It's capable of running Snow Leopard and Lion (but not, I believe ML).
I just bought the upgrade SL discs from Apple and installed them as an upgrade, moving up to 10.6.3 (from the discs). After running software update I'm now on 10.6.8.
Since upgrading I've successfully run Time Machine. However I have the following problems:-
A bunch of emails were present in the Inbox, but contained no body text - just the subject line. I have managed to since find most of them successfully from TM. This is a minor annoyance but I thought I'd mention it.
ITunes won't boot up. It booted the first time I tried it, but since then the little icon just bounces up and down.
Certain apps won't quit properly. I quit from the top menu, but the little blue light remains under the icon in the dock. I then have to 'Force Quit - Application Not Responding' *every time*.
Safari frequently won't load up bookmarked or seach pages, the progress bar gets stuck part way across and I stare at the rainbow pinwheel for ages, before having to quit, then Force Quit, then restart Safari and try again.
Now, I'm tempted to do a Clean Install, but after four international moves (Singapore-Australia-UK-Canada) I no longer have any of the original discs, and thus as I understand it will lose iLife. And iLife 11 needs Lion.
I've done a disc permissions repair thing via the Mac Disc Utility. I've run a few clean-up operations via Onyx.
Any suggestions gratefully received. My Mac as been running great for years, but this upgrade has been extremely disappointing thus far.
thanks
Feargus

Hi baltwo
Many thanks for your advice. I've read all the links and will be buying a 2nd external HD to do a SuperDuper back up. I already had a 1Tb drive with Maxtor back up on it, and I also managed to get a Time Machine back up as well, so at least my data should be safe.
Qn - If I back up the System and Utility folders as well as the Home folder, I don't suppose I can restore them after an install and everything (eg iLife) will 'just work'?
Anyway, I went straight from Tiger to Snow Leopard. I don't have any Tiger discs either (see reasons above) so now have no way of restoring original set up. I tried to boot from the SL install CD and then hold 'C' but must be getting something wrong as I don't get the Disk Utility pop up. It just boots as normal to the desktop.
Anyway, via the normal Disc Utitlity I've done a Repair Permissions again with no major issues. However, my Onyx software now won't run at all so I can't clean any caches a second time.
I've contacted the Apple rep who sold be the SL discs but she's not got back to me yet re iLife.
This weekend I'm going to try a fresh upgrade. If that fails I'll try Erase and Install, if I can get the 'C' button timing right. I'll update if I have any successs.
cheers

Was upgrading from Leopard to Snow Leopard. Install failed. Now says I'm in 10.6 but I'm incomplete. Screen goes gray. Can't boot from disk.
