Macbook air won't upgrade to snow leopard

Hi, I have a early 2009 Macbook Air. I had it sent out a second time, this time they replaced the logic board. But when I got it back it was rolled back to 10.5.8 and I lost my snow leopard installation. I tried to reinstall but it says it can't be installed on my current system? How is that, when I had it running before? I even tried a timemachine restore and it still went back to 10.5.8. I had called and talked with the person I dealt with originally but they were out so I left a message. Really disappointed overall, wondering what the cause of this could be now.

Well I did try the above posted. Calling applecare, they did not do any of the above, instead tried to boot from the 10.6 disk, once it started to install not even half way through the computer would have a kernel panic and ask me to shut the computer off. Starting over again yielded the same result time and again. The tech sent me another 10.6 disk stating that it could be a bad disk. The same kernel panic resulted. I will be sending this out to them for the third time now, but this time apparently I will get "white glove" service. Why I did not receive that in the first place is beyond me. Thanks for your help though.

I have leopard OSX (10.5.8) on a macbook air. want to upgrade to snow leopard (eventually to ML). how? when no disk drive or mac store. thanks

I have a macbook air running on OS X 10.5.8. I wish to run on the new mountain lion. I realise that i am currently on leopard which means i have to upgrade to snow leopard or lion before i can get mountain lion. However because i am on leopard, i have no mac store and because i have an air, i have no disk drive. how do i upgrade to snow leopard or lion without these?
Any help would be greatly appriciated. if i've missed something basic im very sorry

Apple confirmed the removal of the software this afternoon, and said that customers can still purchase a copy from its online store's telesales agents.[1-800-MY-APPLE (1-800-692-7753) or Customer Service and Sales Support at 1-800-676-2775.]
Non-Apple sources for Snow Leopard:
Snow Leopard from Amazon.com
Snow Leopard from eBay
If you call Apple then you should ask about purchasing the Lion USB Flash Drive installer if you want to skip over buying Snow Leopard.
Be sure your model can run Mountain Lion:
Macs that can be upgraded to OS X Mountain Lion
iMac (Mid 2007 or newer)
MacBook (Late 2008 Aluminum, or Early 2009 or newer)
MacBook Pro (Mid/Late 2007 or newer)
MacBook Air (Late 2008 or newer)

Please google search for "Mountain Lion disk crash" before upgrading you mac pro. You might need to replace you Mac hard drive after the upgrade.So many people had the same problems including me.
Be aware of the Mountain Lion upgrade problem.

MacBook won't upgrade to Snow Leopard

I have a Macbook 13" Late 2008 "Unibody" which I just downgraded from Mountain Lion to Leopard.
That really upped the speed of the computer, which really was extremely slow on Mountain Lion.
I then wanted to upgrade to Snow Leopard, for which I purchased a disc ages ago.
I put it in the computer and run the installer which seems to be working just fine. However, after a period of time, perhaps done 20% of the install, the computer reboots taking me to "the new installer" screen. The cursor just loads and the screen won't appear, whereafter the computer just shuts down.
The only way to get the computer working again, is by taking the disc out by left clicking, pushing the disc out. The computer then starts in Leopard....
What am I doing wrong?
Would it help to delete the partition and start over with only installing the Snow Leopard disc? As I recall the disc is only an upgrade.
Appreciate the help.
Kind regards
Peter

How much free space on the startup disk?
Control click the MacintoshHD icon on the desktop then click Get Info.
You'll see: Capacity and Available
Make sure there's at least 15% free disk space.
If there's plenty of free disk space, check the startup disk.
Launch Disk Utility located in HD > Applications > Utilities
Select the startup disk on the left the then select the First Aid tab.
Click: Verify Disk (not Verify Disk Permissions)
If repairs are necessary, insert your Mac install disc.

Boot time for early 2008 MacBook Pro longer after upgrade to Snow Leopard

Hi all,
I upgraded to Snow Leopard about 2 months ago and have found my boot times longer ever since - by about 5-10 seconds. Any idea what could be causing this?
btw all patches to SL have been applied including the most recent OS update, 10.6.4.
Thanks!

Thanks. Now I could back it up. It even booted. But now I have a new problem. The new hard drive is reallz faster than the old one. But Evers now and then the system just freezes. Not like when it was overworked before with the old system. No it completely freezes. You can just move the mouse then. But you can move windows, can't click on anything. This lasts about 30 seconds, then everything is normal. Is there a size maximum for a internal hard drive or cache max or a speed max. It makes go crazy.
But never the less. You first hit helped. Maybe you have another one.

MacBook Pro Won't Sleep after Snow Leopard Install

Neither closing the computer, or selecting Sleep from the menu will allow my computer to enter slumber. Shorty after closing its eyes, my computer will make that unsettling grinding noise and wake up.
I've reset the PRAM, the PMU, turned off bluetooth, airport, all running applications. This only started happening after installing 10.6.
I found a thread on MacRumors discussing this problem, but there was no fix yet. So I bring it here. Can anybody guess what's up, or should I just take it in to the Apple store?

Don't bother taking it to the Apple Store. They won't be able to help. This is a bug in Snow Leopard. I don't know of any workaround or any way to make it stop. It doesn't happen all the time. Usually shutting down the machine will fix it. Sometimes, it will fix itself after a while.
It is important that you never assume a machine is going to go to sleep successfully. Always wait for the pulsating light. If it does go to sleep, chances are it will stay that way. I used iLid Preference Pane to make sure that my machine doesn't accidentally wake up while it is in a bag or something.
I've already filed a couple of bug reports about it. You can help you sending your feedback to Apple.

MacBook Pro won't boot into Snow Leopard

Hello all,
I've been running Snow Leopard for a few weeks now with no problem, but today my laptop refuses to boot into the Snow Lepoard partition, it is stuck on a grey screen with the logo and a spinning wheel.
I have tried booting into safe mode with no luck. Also I have a Windows boot camp partition which I can boot to and work properly, and finally I have booted from the Snow Leopard disk and run disk utility, the HDD can be verified and the only warnings I get when repairing permissions are about SUID files being modified and will not be repaired. I don't know if that s the root of my problems, any advise will be greatly appreachiated (sp?).
Thanks

Thanks for the help, but I would like to know what went wrong and how to avoid this in the future.
I've usually found that such problems are accompanied by hard drive damage, but you say it's testing fine, so that's obviously not it. But sometimes vital files get corrupted somehow and you never know why, unfortunately. It could have its roots in some application crashing a year ago.

I re-installed by OS on my MacBook Pro, the tried upgrading to Snow Leopard

Only to receive a message saying that it cannot be installed in this computer.....WTW?, I bought that CD fair and square from the A-Store
Should I even bother going into Mountain Lion?
I am currently running: Mac OS X 10.5.8 (9L31a) with a Darwin 9.8.0 Kernel....
Thoughts......comments....

I had a similar issue long ago. I dont remember exactly what apple explained the issue as...but I can tell you exactly what I did.
1. Back up. I backed up my entire machine using time machine (suggest an external harddrive, but the cloud system could work (though most if not all are paid)
2. Go to an apple store
I took my comp and install disk to them and they removed the internal drive, took it to the back, and returned with the new OS installed.
(This is abit of a pain if you have a desktop)
you could presumibly bring the drive itself but I wouldnt suggest it unless you know what your doing.
Several people at my school had a similar issue, and I'm guessing its just upgrading from 10.5 ->10.6 as thats the only time Ive ever had an issue with changing OS

My computer doesn't recognize a disk to upgrade to snow leopard

Hi
I have macbook version 10.5.8 (model identifiner: MacBookPro5,3, i bought it in 2009) and bought a install DVD to upgrade to Mac OS X Snow Leopard (version 10.6.3). Before I bought the disk from apple store, I chatted with the costomer servise and they said it's the right disk to buy. But my computer doesn't read the disk and keep rejecting. Does anyone know why this happens or How I can solve this problem?

If it's the white Snow Leopard disc, then it's the correct one and any MacBook Pro can be upgraded to Snow Leopard.
Will your drive read other discs? It may be that your drive lens just needs a good cleaning - you can try one of the commerical CD/DVD lens cleaning kits sold at most electronics store and give that a try. If that doesn't work then I would take the disc back to the Apple Store along with your computer and let them have a go. If there's a mechanical problem with your SuperDrive they'll be able to diagnose that as well.
Good luck,
Clinton

When i upgrade to snow leopard do i need to buy a version specific to my macbook air

when i upgrade to snow leopard from leopard do i need to buy a version specific to my 2008 macbook air

Welcome to Apple Support Communities
You can use the Snow Leopard version that is used for all Macs > http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard#
Make a backup before upgrading. Also, as you have a MacBook Air, it hasn't got a SuperDrive, so you have two options to install Snow Leopard:
1. Use DVD or CD sharing from a different PC or Mac, as stated in the Snow Leopard installation steps > http://manuals.info.apple.com/en_US/Snow_Leopard_Installation_Instructions.pdf
2. Get an external DVD drive and use it to upgrade to Snow Leopard.
I recommend you to get an external disc drive, so installation will be faster. After upgrading, open  > Software Update, and install the latest version

Encrypted .dmg won't mount after upgrade to Snow Leopard

Just upgraded to Snow Leopard and having trouble mounting an encrypted disk image that I use for my confidential files. I have tried mounting using both DiskImageMounter.app and the Disk Utility but both give error 60008, unable to attach.
Anyone else having similar problems or have suggestions for alternative ways of mounting?
Best,
Jon.

My encrypted disk image with confidential files was created under Leopard using Disk Utility. I just upgraded to Snow Leopard and when I try to mount the image, the password box comes up (as before the upgrade). But, I enter my password, and the disk image does not mount, it just keeps asking for the password again. I also have the latest MacBook Air and I also have an encrypted disk image there too with the same problem when I try to mount it. In addition, I have a LaCie 1TB External Harddrive that contains an encrypted disk image. When I try to mount this disk image, which normally appears on the desk top, I get the same repeating password box. Entering the password does nothing--other than causing the password box to reappear. All three encrypted disk images worked fine without any issues before the upgrade. So, based on the number of views that this post has had, this appears to be an issue that needs a resolution. Any suggestions or others with similar problems?

Upgrade from snow leopard 10.6.8 to montain lion on a iMac system won't boot getting a crossed out circle

Upgrade from snow leopard 10.6.8 to montain lion on a iMac system won't boot getting a crossed out circle

Clean install OS.10.6.8 update it completly. May be you ignored some firmware update.
I have two incedents.
My thunderbolt port stopped working after upgrading to ML 10.8. I booted from external 10.6 , 10.7 still didnt work. Then i clean installed 10.6.8 and ran software update it updated the thunderbolt firmware and all is well now. This firmware update for some reason didnt show up in ML 10.8.
Secondly , when i upgraded my Brother's Macbook from 10.5 to 10.6.3 it would install but stuck with crossed out circle. Then i downgraded checked for update found an efi update , then the 10.6.3 worked fine.

Your machine likely can't handle Mountain Lion 10.8 nor 10.7, if it does it will run slow and very higly likely a lot of your third party software and drivers for printers and scanners won't function anymore.
It's because your 10.5 era (or earlier) machine is rather dated, hardware has advanced and is faster, the newer OS X versions have gotten bloated.
I do recommend you call Apple via phone and order the 10.6.3 white retail disks, backup your personal data off the 10.5.8 Mac to a external storage drive and when the disk arrives, stick it in and run the upgrade installer.
Once that's finished, reboot and use Software Update to get to 10.6.8 and stay there. You can buy stuff from AppStore, just don't upgrade to 10.8 (or 10.7) as thats when you'll have issues.
10.6 should run your currrently installed PPC software and hardware drivers. But 10.7/10.8 will not.
10.6 is receiving security and other updates from Apple as more than 50% of OSX users are still on it.

Things to consider before upgrading OS X

You don't need to update to Leopard 10.5.8 unless you want to keep Leopard. Upgrading to Snow Leopard requires that your purchase the retail install disk.
The following covers Leopard:
Some general advice on updating:
It is worth noting that it is an extreme rarity for updates to cause upsets to your system, as they have all been extensively beta-tested, but they may well reveal pre-existing ones, particularly those of which you may have been unaware. If you are actually aware of any glitches, make sure they are fixed before proceeding further.
So before you do anything else:
If you can, make a full backup first to an external hard disk. Ideally you should always have a bootable clone of your system that enables you to revert to the previous pre-update state.
Turn off sleep mode for both screen and hard disk.
Disconnect all peripherals except your keyboard and mouse.
1. Repair Permissions (in Disk Utility)
2. Verify the state of your hard disk using Disk Utility. If any faults are reported, restart from your install disk (holding down the C key), go to Disk Utility, and repair your startup disk. Restart again to get back to your startup disk.
At least you can now be reasonably certain that your system does not contain any obvious faults that might cause an update/upgrade to fail.
3. Download the correct version of the COMBO update from the Apple download site.
The Combo updater of Leopard 10.5.8 can be found here:
http://support.apple.com/downloads/Mac_OS_X_10_5_8_Combo_Update
If you prefer to download updates via Software Update in the Apple menu (which would ensure that the correct version for your Mac was being downloaded), it is not recommended to allow SU to install major (or even minor) updates automatically. Set Software Update to just download the updater without immediately installing it. There is always the possibility that the combined download and install (which can be a lengthy process) might be interrupted by a power outage or your cat walking across the keyboard, and an interrupted install will almost certainly cause havoc. Once it is downloaded, you can install at a time that suits you. You should make a backup copy of the updater on a CD in case you ever need a reinstall.
Full details about the 10.5.8 update here: http://support.apple.com/kb/HT3606
More information on using Software Updater here:
http://support.apple.com/kb/TA24901?viewlocale=en_US
Using the Combo updater ensures that all system files changed since the original 10.5.0 are included, and any that may have been missed out or subsequently damaged will be repaired. The Delta updater, although a temptingly smaller download, only takes you from the previous version to the new one, i.e. for example from 10.5.7 to 10.5.8. Software Update will generally download the Delta updater only. The preferable Combo updater needs to be downloaded from Apple's download site.
Now proceed as follows:
4. Close all applications and turn off energy saving and screensaver.
5. Unplug all peripherals except your keyboard and mouse.
6. Install the update/upgrade. Do not under any circumstances interrupt this procedure. Do not do anything else on your computer while it is installing. Be patient.
7. When it ask for a restart to complete the installation, click restart. This can take longer than normal, there are probably thousands of files to overwrite and place in the correct location. Do nothing while this is going on.
8. Once your Mac is awake, repair permissions again, and you should be good to go!
If your Mac seems slightly sluggish or ‘different’, perform a second restart. It can’t hurt and is sometimes efficacious! In fact a second restart can be recommended.
9. Open a few of your most used applications and check that all is OK. In this connection please remember that not all manufacturers of third party applications and plug-ins, add-ons, haxies etc, will have had time to do any necessary rewrites to their software to make them compliant with the latest version of your operating system. Give them a week or two while you regularly check their websites for updates.
N.B. Do not attempt to install two different updates at the same time as each may have different routines and requirements. Follow the above recommendations for each update in turn.
Lastly, Apple's own article on the subject of Software Update may also be useful reading:
http://docs.info.apple.com/article.html?artnum=106695
[b]If you are updating Safari (or just have):[/b]
Input Managers from third parties can do as much harm as good. They use a security loophole to reach right into your applications' code and change that code as the application starts up. If you have installed an OS update and Safari is crashing, the very [i]first[/i] thing to do is clear out your InputManagers folders (both in your own Library and in the top-level /Library), log out and log back in, and try again.
So, disable all third party add-ons before updating Safari, as they may not have been updated yet for the new version. Add them back one by one. If something goes awry, remove it again and check on the software manufacturer's website for news of an update to match your version of Safari.
Most errors reported here after an update are due to an unrepaired or undetected inherent fault in the system, and/or a third party add-on.
Additional tips on software installation here:
http://docs.info.apple.com/article.html?artnum=106692
To reiterate, Input Managers reach right into an application and alter its code. This puts the behavior of the affected application outside the control and responsibility of its developers: a recipe for problems. That's not to say that issues absolutely will ensue as a result of Input Managers, but you, as a user, must decide. If the functionality of a specific Input Manager or set thereof is really important to you, you may well choose to assume the associated risk.
Again, the advice is to remove all Input Managers from the following directories:
/Library/InputManagers
~/Library/InputManagers
especially prior to system updates (they can always be added back one-by-one later).
