Boot up time (on Snow Leopard) and clicking sounds...

Hi,
While trying to upgrade to SL my MBA wouldn't boot. I went to an Apple store and they sent it out for repair. Now that I have it back the MBA seems to be more sluggish. While booting (before the Apple logo comes on) I hear a clicking sound. I also hear clicking sounds on other occasions.
Is this normal?
Thanks for your feedback everyone!
Mikey

More data needed: what do you mean more sluggish? It should take a minute or two for your MBA to boot up.
Don't turn it off. Just shut the lid and re-open it when you are ready. It's designed to be put to sleep, not turned off after each use,
The clicking sounds in the MBA come from the hard drive and the fan. They can click from time to time if you are moving your MBA while it is booting up or shutting down...if its clicking sitting on your desk, and this started after the repair, you need to go back to AppleCare for another repair.

Time machine snow leopard and lion

Can I use that same hard drive for lion, and keep the old snow leopard backups ?
Many thanks!

Let me know if is all ok.

NAS-based Time Machine, Snow Leopard and new backups

Hi all,
I have a new NAS server (Netgear ReadyNAS) and have configured my Snow Leopard MBP to use it for its Time Machine backups.
I create the first backup over gigabit ethernet, and subsequent backups occur over wifi.
This happens as normal for about a week or so, until the following error appears:
"Time Machine completed a verification of your backups. To improve reliability, Time Machine must create a new backup for you.”
So, twice now, I've duly plugged in my MBP and it starts a backup from scratch, copying the usual 450ishGB over onto my NAS. I then disconnect, and the backup works fine for a week or so, until the error appears again.
The only blogpost or help article I could find relating to this is here: http://www.garth.org/archives/2011,08,27,169,fix-time-machine-sparsebundle-nas-b ased-backup-errors.html but when I follow that process, I get the ultimate error:
"** The volume Time Machine Backups could not be repaired."
The backups are perfectly sound - I do a test restore of a random file daily - but this error is very annoying.
Any ideas as to how I could repair it? Or as to what might be going wrong on my backup volume?
Thanks,
Maritn

Let me know if is all ok.

Dual boot machine- snow leopard and Lion

It appears I will need to set up one of my machines as dual boot, containing partitions for Snow Leopard and Lion. The reason is that Quicken is NOT compatible with Lion, and will apparently never be. Intuits "solutions" are to go to other, far less capable software, or not upgrade. Which, of course means, NEVER upgrade again.
So, I think my best solution is to set up a partition for snow leopard and one for Lion. How do I go about this? Size of partition. How to partition? Which boot disks do I use to do this?
Any help is much appreciated.

Ok, I just got done doing this yesterday so I can lay it out for you.
1: Copy all your user files to a regular external drive and disconnect.
2: Carbon Copy Cloner your 10.6.8 setup to another blank HFS+Journaled external drive and disconnect.
3: Hold c and boot off the 10.6 installer disk and erase your entire boot drive in Disk Utility (under the Utilities menu) format HFS+Journaled (default) of course.
4: Quit and install 10.6. Setup with the same user name as Snow. Run the 10.6.8 Combo Update. Then Software Update.
http://support.apple.com/kb/DL1399
5: Use the MacAppStore to download Lion, BUT DO NOT INSTALL yet! Cancel it and click on the Installer and select "Show in Finder" follow these instructions to make boot DVD's and dmg images of Lion installer.
http://www.eggfreckles.net/tech/burning-a-lion-boot-disc/
6: Once you do that, then Install Lion. On a pristine 10.6.8 with no third party programs or other BS it should go perfectly. Check it out that it's stable just in case or else hold command r and boot into the Recovery Partition and redownload/install again.
7: Once that's done and Software Updated, run Bootcamp and create a Windows partition larger than your 10.6.8 clone naturally. The size is up to you to decide. Cancel the Bootcamp when the partition is created.
8: Hold Option and boot off the 10.6.8 clone with all your stuff and programs, use Disk Utility to change the "BOOTCAMP" partition to "Snow Leopard" and make it a HFS+ Journaled partition from the MSDOS format (not the whole drive now or you'll lose Lion and the Recovery Partition) If this doesn't work then use Disk Utility c booted from the 10.7 DVD or command r from the Lion Recovery Partition and use Disk Utility there.
9: Once that's done, Option boot off the 10.6.8 clone and Carbon Copy Clone 10.6.8 onto the Snow Leopard partition.
Walla, a dual boot system with all your stuff intact. Just hold option upon boot and/or use the Startup Disk in System Preferences to set a default.
I'm currently working on a quad boot system now. It's got Lion, Snow, Linux and will have Windows too. A lot more complicated than simply Snow and Lion.
Note: OS X Lion reguires a internet connection to install, even from a boot DVD.
Enjoy.

My MACBOOK Pro turned out to be Snow Leopard, and later upgraded to LION. And update the EFI, I would like to replace the Snow Leopard, EFI can not boot, how do? How to use the Snow Leopard install disk to reduce EFI?

Do you mean some of your software does not work in Lion? Do you want to return to using Snow Leopard? If so, then do this:
Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

Dual Boot Snow Leopard and Leopard

Hi All
i am looking to Dual boot my Intel iMac with Leopard (10.5.8) + Snow Leopard (10.6) for testing purposes.
How do i go about doing this?
I have the Leopard install disc
i do not have Snow leopard yet and the only version i have seen is an update disc you can buy from apple for about £25 is this ok to use or will i need a copy of the full version?
if i need a copy of the full version where can i find it?
my current hdd setup is:
1 partician very large for data about 255GB
+ another 40GB Partician with Mac OS X
I assume i will need to create another partician about 20GB and call it Snow leopard and use the leopard disc to install onto the new partician then upgrade the newly installed leopard partician with the new snow leopard disc??
Thanks in advance
Regards Sam

Apple has managed to fool a lot of folks with their pricing. If you paid the US$129.00 to upgrade your Mac from Tiger to Leopard, then you qualify for the US$29.00 upgrade from Leo to Snow Leopard. If you did not upgrade from Tiger to Leo, you should buy the US$179.00 box set, which includes Snow Leo, iLife '09 & iWork.
All of this is based on honesty and ethics. The Leo disks are the same. The Leo disk in the upgrade does not look for evidence of Leo, at least not to install. You can erase and install with the Leo disk, or install on a virgin HDD that has never seen Mac OS X.
We create dualboot systems when we seed test Mac OS X all the time. SuperDuper will make Sandbox partition and install just Mac OS X and Apple apps. It leaves 3rd party apps, your data and user accounts and settings on your main Mac OS X installation. Then we lay the new version of Mac OS X over the Sandbox and boot into it. So we have the current Gold Master of Mac OS X and the new version that we are testing, and we can boot into either and they both share our data and accounts.
That may be more tricky when you are using different versions of Mac OS X, as opposed to different updates of the same version. For example, Leo and Snow Leo have different versions of many Mac apps. I do not know how they might handle your stored data if they handled the creation of music or photo libraries differently.

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.
"disk utility Info" when verinfying the secondary drive in the oprical bay:

External HDD Issues with Snow Leopard and Time Machine

Hello,
I have a 1TB WD 10EADS External HDD, and it had some files on it. I connected it the other day to an iMac I recently upgraded to 10.6, and wanted to do a complete time machine backup of the computer to it (250GB HDD). I copied the files off the external HDD I needed and then Time Machine needed to format it as it was a FAT32 drive. This went successfully, and I started the Time Machine backup. This went quite slowly and failed after ~2.5GB or so. I restarted and tried again to no avail upon which Time Machine told me I should reformat it in Disk Utility. So I did, and to no avail.
I tried this a number of times and sometimes when doing a reformat I was told that the drive could not be unmounted. I tried manually copying files to the disk which started to work but then failed promptly with error (-36) and the message "The Finder can't complete the operation because some data in “ [Program/File Name]” can't be read or written." I upgraded to 10.6.1 also to no avail. I even repaired permissions and the disk, and booted Disk Utility from the Snow Leopard disc and formatted that to no avail.
I have read this is an I/O error and can be associated with bad drives, but as I stated before, the drive worked perfectly until Time Machine formatted it. I took the HDD to another Mac running 10.6, and it told me it had a POSIX error. I did some googling and found that if I format it under a Windows machine, and then reformat under the mac it might work.
What I want to know is, is this a 10.6 error or has the HDD decided to go kaput after Time Machine formatting it?
Thanks for your help

Time Machine backup failed. I think it's a glitch with the computer, not the HDD. Going to zero out the drive now.
Any other suggestions on how I might bypass this error to get data onto the Disk eg. transfer over to another computer, so I can reformat the computer and install Snow Leopard from scratch? The whole purpose of doing this time Machine backup was to get all the files off the computer to perform a clean install of Snow Leopard.
I assume you're positive the TM disk has both the correct *Partition Map Scheme* (GUID) and Format (Mac OS Extended (journaled), but not case-sensitive)? One of them being wrong is the most common cause of a first TM backup failing.
Did you do either a +*Verify Disk+* (not permissions) or a +*Repair Disk+* (not permissions) on your internal HD, or only your TM drive? The message you got could be a result of a problem on either one.
Other options are to make a "bootable clone" via CarbonCopyCloner or SuperDuper. CCC is donationware, SD has a free version that will do it. If you do that, boot from it, and be sure everything works before erasing your internal HD. Google them.
Note that there are many, many reports of problems here with WD drives, and that some of them are not bootable.
I would not upgrade without backups (Murphy was an optimist!), but is there a reason you want to erase your HD? It's not required, and rarely does any good. The normal install will simply install Snow Leopard and remove Leopard. Your apps, data, etc., won't be touched.

Install boot camp snow leopard and mountain lion

Is it possible to install boot camp on a 2009 Mac Pro to run both Snow Leopard and Mountain Lion? The startup drive is already partitioned. I need to run two different versions of Final Cut Studio (and all the accompanying apps) and this seems the best way to keep them segregated. I know that I can run them both in Snow Leopard, but I have two different sets of Motion templates which need to be accessed.

Alrighty, I do appreciate your time. I had already tried parallels and that was a huge waste of time. You blow away their support, by the way.
Just to confirm assumptions before I do this, sorry, I'm an engineer.
1. The startup drive is partitioned already.
2. Partition (1) contains Snow Leopard and a user account.
3. Partition (2) currently contains a media library, does not have an OS on it, and has 232 GB free.
4. I will install Mountain Lion on partition 2 using the dmg downloaded from the app store.
5. That partition will then become the startup drive when using mountain lion.
6. Partition 2 will have its own user account, applications, etc.
Almost forgot. Do I need to erase and install on that partition or can I simply install? After this I owe you a beer.

Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

I recently upgraded to snow leopard and now every time i open iCal i get multiple events to update in iCal

I recently upgraded to snow leopard and now every time i open iCal i get multiple events to update in iCal. Except I don't know where these are coming from or why. I've check iCal preferences and Help - can't find a way to stop this from happening automatically. Any Clues? Also, some of the events are already on my calendar and have been for quite some time.

Greetings,
What do you mean by "events to update"? Do you mean invites to new events or changes to existing invites?
Troubleshooting:
1. Your profile indicates you are running 10.6.7, 10.6.8 is the current version Apple > Software update.
2. First make an iCal backup: Click on each calendar on the left hand side of iCal 1 at a time highlighting it's name and then going to File Export > Export and saving the resulting calendar file to a logical location for safekeeping.
3. Remove the following to the trash and restart your computer:
Home > Library > Caches > com.apple.ical
Home > Library > Calendars > Calendar Cache, Cache, Cache 1, 2, 3, etc. (Do not remove Sync Cache or Theme Cache if present)
Home > Library > Preferences > com.apple.ical (There may be more than one of these. Remove them all.)
---NOTE: Removing these files may remove any shared (CalDAV) calendars you may have access to. You will have to re-add those calendars to iCal > Preferences > Accounts.
3. Launch iCal and test.
Hope that helps!

Snow leopard and time machine

Hi, I'm using an iMac 21.5" middle 2010 with Mac OS X snow leopard and Time machine on a Time Capsule with 2 GB.
Since yesterday the control light is permanantly flashing yellow, but nevertheless time machine is working an signed a complete bachup, last 2 hrs before.
I'm not sure, if all is correct. Can anybody help?
Many thanks
scharamer

It may just be telling you about the latest firmware update.
Start AirPort Utility (in your Applications/Utilities folder).
Click Manual Setup
Click directly on the word Status (2nd line) and AirPort Utility will indicate what's wrong.
If your network seems to be working OK, the flashing light might indicate that an update for your AirPort device is now available.

Is it possible to have both Snow Leopard and Lion at same time on one machine without creating a mess?

I currently use Snow Leopard because I like the way it preserves the operation of OS10 PPC programs. I have both an expensive CAD program and Adobe Photoshop CS3 which are PPC programs.
Can you launch your machine with Lion when you want to use that, and launch with Snow Leopard when you want that. Its too bad Lion does not support PPC OS10.

Absollutely. This is a very common practice whenever a new OS or OS update comes out. By far the best way to do what you want is to install Lion onto an external firewire 800 disk, then boot off it when you want to use Lion and boot off your iMac's internal disk when you want to use Snow Leopard. USB 2 will work, but firewire 800 will be faster.
The second best option is to partition your iMac's boot drive, then use one partition for Snow Leopard and the other for Lion, but be sure to back up your boot drive to an external disk drive before you partition it.
You can switch operating systems during a restart by holding down the option key.

I have a MacBook Pro 15" and my warranty just ran out! I partitioned my harddrive into two partitions, one with Snow Leopard and the other with microsoft.This morning I turned on my Macbook Pro and it will not boot into Snow Leopard.

Good Morning,
I have a MacBook Pro 15" and my warranty just ran out! I partitioned my harddrive into two partitions, one with Snow Leopard and the other with microsoft.This morning I turned on my Macbook Pro and it will not boot into Snow Leopard. I shut it off took out the battery, reinstalled the battery. Then I put in the Snow Leopard CD and booted up to disk utility and The Snow Leopard partion would not show up?? I do see the microsoft partion.
I also rebooted holding down the shift key and still no Snow Leopard
Could you please tell me what I can do, what keys do I press on restart any advice to get Snow leopard back.
thank you.

Have you restarted holding down the Opt key? That procedure should give you a gray screen with all of the partitions that exist. Then select the SL partition for boot. Also go to System Preferences and Startup Disk, unlock the lock and select the SL partition as the default boot partition, then relock.

How do I Restore from Time Machine after I have reinstalled my system software (Snow Leopard and then Lion) ?, How do I Restore from Time Machine after I have reinstalled my system software (Snow Leopard and then Lion) ?

I have never done this before, so can someone explain in detail how I reintall my system software and then restore from Time Machine please ?

Your profile indicates that you currently have an older version of Snow Leopard (10.6.2). In order to install Lion, a prerequisite is the latest version of Snow Leopard (10.6.8). Perhaps a few more details would be helpfull in solving your problem. ex. If all you want to do is to upgrade to Lion, a restoration of data is unneccessary. Download the latest version of Snow Leopard and then download (purchase) and install Lion. User data will remain intact.
If I am missing something, please elaborate.
Ciao.
