Can't boot USB to upgrade Snow Leopard to Mavericks

I want to install fresh Mavericks on Mac #1 (w/ Snow Leopard). Created bootable USB on Mac #2 (runs Mavericks). Mac #1 will not boot it, tried using option key at boot; tried setting as startup disk in preferenes but preferences does not see it as a boot disk; booted the Snow Leopard install disk and used its startup disk utility, it does not see the USB as bootable. Mac #2 boots the Mavericks Install Utility from this USB device just fine (so I am confident that the USB device was configured and loaded correctly), but Mac #1 will not. I have repaired the USB drive and permissions on the Mac #1 hard disk in DIsk Utiity.
Any suggestions???
Frustrated!!!

Tnx E.R. I am trying to install a fresh Mavericks (vs. upgrading Snow Lep), that's why I built the boot disk on the USB drive.
I did try upgrading my Snow Lep to Mavericks, THEN tried to boot from the USB to do a fresh install, but that did not help... same behavior. So it's not a Snow Lep / Mavericks issue.
I guess the gist of my problem is, my USB drive configured with Mavericks installer boots on one machine just fine, but it is not recognized as a boot drive on the other.

Upgrading Snow Leopard to Mavericks on MacBook Pro 7.1

IS there anything special i should be aware of.... I have 8 mg ram and 480 SSD installed

My advice would be to use Carbon Copy Cloner to make an exact copy of your drive before doing the upgrade. That way if you hit any snags it's very easy to go back. It's much harder without the clone.

I want to upgrade from snow leopard to Mavericks, but only Yosemite is available!!

How do I upgrade snow leopard to Mavericks on one of my older macbooks? I note that Mavericks is no longer available via the App store, only Yosemite, and I do not want the latter. My latest macbooks all have Mavericks pre-installed, and I want parity on all.

OS X 10.9 Mavericks is no longer an available, downloadable OS version.
You can choose to decide and download the free OS X 10.10 Yosemite OR pay to download either OS X 10.7 Lion or OS X 10.8 Mountain Lion.
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.
OS X 10.7 Lion system requirements
Purchased emailed download code here.
http://store.apple.com/us/product/D6106Z/A/os-x-lion
To use OS X 10.7 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 (free upgrade, but currently unavailable) or OS X 10.10 Yosemite (currently available free upgrade) 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.

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 these 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.
Good Luck!

Help! Upgraded Snow Leopard now I can't even log in

Just upgraded Snow Leopard(I think it was the update from 10.6 -> 10.6.2) on my Macbook pro via the software updater. At the end of the installation I got a message saying that there was an error and the update didn't install correctly. I restarted the mac normally and got a log in screen (which I never had previously). I enter my password correctly and then get a blue screen for a few seconds before it brings up the login page again. I can't find a way around this. I know I have entered the password correctly because the login screen doesn't shake.

You have a hosed installation. Step one is to try to boot into safe mode. Details in http://support.apple.com/kb/HT1564 and http://support.apple.com/kb/HT1455 If able, then download the 10.6.2 COMBO update and reinstall it. Hopefully, that will fix the issues. If not, boot with your SL install disc and reinstall 10.6.0. Alternatively, restore the bootable backup/clone or Time Machine backup of your previous installation. See these for details:

I have upgraded Snow Leopard with Combo 10.6.8, the supplemental update and fixed permissions, but still can't open app store to upgrade to Mountain Lion. I am on the Cayman Islands. Thanks for the help!

Don't be afraid to bump this topic. There's also an App Store forum where you might repost this question, but give some of these details in your post. I'd rephrase the topic to something like "Can't use App Store to upgrade." (Instead of can't "open".) Then give the details.

Can I still upgrade from Snow Leopard to Mavericks, with Yosemite out?

Hi there,
my girlfriend is running Snow Leopard (10.6.8 I believe) on a MacBook 2009. Now she finally wanted an upgrade to a newer OS. However, I've read in several reviews that Yosemite is not running very smoothly on some older Macs. So I thought upgrading to Mavericks might be a better deal.
So my question is:
How can I upgrade from Snow Leopard to Mavericks? Apparently you can't do it over the AppStore, since you can now only download Yosemite. Is there another way?
Thanks!

Nope. Mavericks is no longer available for download unless you had downloaded it in the past. If Yosemite doesn't do well on an older Mac, then neither will Mavericks. Consider rolling back to Snow Leopard.
You may try calling Customer Service: Contacting Apple for support and service - this includes international calling numbers. They may be able to help you with getting Mavericks for now.

If you have not previously purchased Mavericks from the Mac app store, then no. It is no longer available. Yosemite has the same system requirements as Mavericks and is a free upgrade from the app store.

Can I upgrade Snow Leopard to Lion from a backup system?

Hi,
This is a bit of a roundabout question so let me establish what's going on:
-I just got a new Mac Pro 6-core a few days ago, which arrived with Lion installed.
-I backed up the fresh Lion system to an external drive and downgraded to Snow Leopard to retain compatibility with certain apps.
-I imaginge somewhere down the line I will have to follow suit and upgrade to Lion/Mountain Lion, so....
Is there ANY way I could use my backup of the fresh Lion system to upgrade my Snow Leopard (if need be) to prevent me having to purchase Lion to upgrade Snow Leopard instead?
Thanks for your help!
Andrew

Is there ANY way I could use my backup of the fresh Lion system to upgrade my Snow Leopard (if need be) to prevent me having to purchase Lion to upgrade Snow Leopard instead?
Aside from the fact that it will probably not work, the point is that your license for the preinstalled Lion is only good for one machine. If you want it on any other machine, you will need to buy it. Why don't you just wait until you want to install Mountain Lion - if the terms are the same as they were for Lion, it'll cost you $20 to update all your machines.

Since updating to Lion I can no longer screen share on Snow Leopard

Hi all,
I'm hoping someone might have some insight to the problem I'm experiencing with Screen Sharing. I have two macs that I use - one is a Mac Mini 2010 Server model running Snow Leopard. The other is a MacBook that is running Lion.
Since updating to Lion on the notebook, I can no longer access screen sharing through the Mac mini to the MacBook (Can't see the Lion screen through the computer with snow leopard). I AM able to screen share the other way (see the snow leopard screen through the macbook running Lion).
It's aggrivating, in as much as these computers are on two different floors of my company, and being able to see the screen makes life easier.
I should also point out that I am able to successfully share the hard drives / files between both computers going back and forth (Snow Leopard to Lion and Lion to Snow Leopard) - it's just the screen sharing that no longer functions. When I attempt to access the other computer screen it will act like it is signing in but just hangs and does nothing.
I know there is probably much more information that someone will need to help me solve this, but I don't know where to look. But I'm hoping that with at least this much information you might be able to tell me where to look to get this corrected.
Much thanks.

If you want.
or maybe install Snow Leopard using the disc it came on with my Mac and just set it up from a Time Machine Backup on my external hard drive (since it works under SL)?
Did you install Lion on an empty partition, or did you upgrade Snow Leopard? If you upgraded, I'd not recommend erasing it, since your backups are apparently gone. It's doubtful Snow Leopard will recognize them.
It's not just backups on the drive either, there are other important things on there, so why won't they show?
Mixing Time Machine backups and other data is not a good idea. See #3 in Time Machine - Frequently Asked Questions. It sounds like the whole disk is corrupted.
I just really don't understand how this happened. Could it not be an issue with WD because they haven't issued firmware to support Lion yet?
If this is a simple external HD, connected by USB or FireWire, no, unless you installed some of WD's software on it. That shouldn't prevent it from being seen at all, but anything's possible.

Dual Boot with Snow Leopard and Mavericks not possible?

I have a Early 2011 Macbook Pro with 2,3 GHz i7 Quad and two 512 GB SSDs (the secondary disk in an optical drive bay enclosure). This Macbook Pro can run Snow Leopard and Mavericks on the primary disk without problems. When I try to set up a dual boot system however, problems appear and it looks like it is not possible. When I start from Snow Leopard, I cannot select Mavericks as a start volume and vice versa. The error message says something like "Bless tool" cannot use this disk, i.e. unmount and boot from it. The problem remains when I exchange the disks (putting the primary disk in the drive enclosure and vice versa). When I put the secondary drive in an external case however, it is possible to boot from it - but strange things happen when the system starts: My computer clock is reset to 1/1/2001, WiFI passwords are not remembered for more than one session, disk permissions are reported as "repaired" but do apear as not repaired when I check them again - and other issues). I have verified both disks already and repaired permissions but that does not change the situation. So my experience is different from what is said in https://discussions.apple.com/thread/566781. It looks like the latest Mavericks cannot coexist with Snow Leopard on neiter a secondary internal drive nor on an external drive. This is strange since both disks and systems work flawless when run alone. Any suggestions to solve this problem?

When I check the Mavericks disk in the optical drive with disk utility after booting / running Snow Leopard on the primary disk I get som errors, see below ("disk utility Info"). So after all, I decided to erase the disk and install Mavericks new. But even erasing the disk is not possible when it is in the optical drive enclosure. I get this error message:
"Volume Erase failed with the error:
Could not unmount disk"
When I put this disk into an external case connected via USB however, it starts and runds MAvericks without any Problem. Same happens when I put thie Mavericks disk into the internal primary hard disk place.

Upgrading Snow Leopard to 10.6.2

I have downloaded from Apple the latest version of Snow leopard 10.6.2.I am trying to upgrade Snow leopard since about a month.. Every time I attempt it the Sound disappears. I am really fedup. Local Apple support desk is just useless. They have absolutely no idea what is happening. I called Apple care and they suggested that I move some files in ~/Library on to the desktop and try..Nothing has happened. All I am doing is wasting my time. I have to revert back to 10.6 by using the CD I bought. Apple care support must have some really trained staff if they want to make a dent in the Indian market.. which unfortunately is not the case..
Can anyone help me in this problem?? Thanks in anticipation

Create a new User go to System Preferences >> Accounts >> "+" (make it an admin acct) and test the apps in this new account, if they work the problem is isolated to your User and not systemwide.
If the issue is limited to your user account try starting up Safe Mode (It will take more time to startup in Safe Mode because it runs a directory check.)
If your apps functions correctly that way, go to System Preferences >> Accounts >> Login Items, and remove them. Boot normally and test. If not go to ~(yourHome)/Library/Contextual Menu Items and move whatever is there to the desktop. Then do the same with /Library/Contextual Menu Items. Lastly, try moving ~(yourHome)/Library/Fonts to your desktop and restarting.
Log out/in or restart, if that sorts it start putting items back one at a time until you find the culprit.
If the issue is systemwide then, you may be able to repair this with the The 10.6.2 Combo Update This is a fuller install, as opposed to an incremental "delta" update so it should overwrite any files that are damaged or missing. It does not matter if you have applied it before.
Remember to Verify Disk before update and repair permissions after update from /Applications/Utilities/Disk Utility.
Let us know.

Snow Leopard to Mavericks upgrade question!

1st I'm sorry if this is a question that comes up all the time but I'm just a little scared to do the upgrade.
I am a video editor and I use both FCP7 and Adobe Pr 5.5 (looking to upgrade) on my MacBook Pro (2011) 2.4GHz i5 4GB RAM on 10.6.8 NVIDIA GeForce GT 330M
I want to upgrade but I'm worried because I have some ongoing projects and I can afford to lose anything and normally I would not upgrade with ongoing projects but I may have to soon.
I did a time machine backup on everything I guess my question is, is there a way I can do the upgrade and if something goes wrong I can just go right back to Snow Leopard with my time machine backup?
I know this may sound stupid but any input would be great guys.
Thanks!

It is better to have a bootable clone on its own partition rather than have other files on it as well. I would temporarily move my files off the external (to your internal?), re-partition the external so there are two partitions, move back my files to one, and then clone my internal hard drive to the other. I use CarbonCopyCloner and have bootable clones of every OS I have. It is the fastest way to come back from a disaster: simply boot into the clone, erase the internal hard drive and clone the system back. Done.

If i upgrade Snow Leopard to lion, all information will be removed? from hard disk ?, if i upgrade Snow Leopard to lion, all informatio will be removed from hard disk ?

John Hammer said it best -- backup first and always. That's why Time Machine and periodic clones of your boot drive to an external disk are so valuable.
That said – the Lion upgrade will retain all user data, files, settings, mail, and preferences. Mind you that a few settings and their location have changed.
Before you actually use Lion, may I recommend spending the first evening looking at every single preference panel in System Preferences. Many of the user interface choices can be reverted back to mimic Snow Leopard if you choose.
Relax and enjoy Lion – it is amazing. Please holler if we can help further.

How to install upgrade snow leopard in macbook pro?

I bought a macbook pro 2011 2.2 ghz quad core i7 and would like to install snow leopard in one partition to run older software. I had the full version of os leopard, but can't install in the new macbook pro to upgrade to snow leopard. I can't upgrade snow leopard in my power G5 either because it needs intel cpu. Is there away to upgrade leopard to snow leopard in macbook pro 2011? I have not bought the snow leopard upgrade yet. Thank for your help.

See the bottom of this user tip to determine if Snow Leopard can be installed on your MacBook Pro:
https://discussions.apple.com/docs/DOC-2455
If it can, you'll need to find out the version of Snow Leopard installer that was available at the time that machine was released based on the age of the machine.
Snow Leopard releases are here:
10.6.6 on January 6, 2011
10.6.7 on May 4, 2011
10.6.8 on June 23, 2011

How can i get xcode for osx snow leopard?

how can i get xcode for osx snow leopard?

I'm an experienced software developer (C, C++, Lisp, Linux, Unix, etc) but have never done any Mac development, and wanted to try some stuff on my iMac at home, but I have Snow Leopard and most of the turtorials I looked at said the first thing I had to do was download XCode and the first thing that happened when I tried to do that was it said I had to upgrade to Lion.
My iMac is running SnowLeopard. I don't have any big reason to stay at SnowLeopard, but from stuff I've seen in the forums I can't see any big reason to upgrade to Lion. I might eventually want to do development for IOS on an iphone or iPad, but for now I just want to do a simple tutorial app for my iMac.
I found the downloads search page, and it looks like there's two versions of Xcode 3.2.7 which has a release date of Sep 2011, and 3.2 with a release date of Jan 2012.
Which one should I download? And if I download one of these will it be a problem if I do upgrade to Lion in a few months?
