IMac OS X Lion update and backup help needed

Hello have a few questions I really need answered, so thank you for looking a this discussion.
1) I have a Mac OS X Version 10.4.11 2.16 GHz Intel Core 2 Duo. I'm hoping to upgrade to the OX S Lion now in July, so that means I need to back up my data right? My real question is will the Time Capsule work with the operating system I have now? Also which one should I get? I have around 100 GB worth of pictures, music, and video.
2) Will OS X Lion even work on the computer I have now or is it too old?

1. Yes, you should backup. Before you do you should do the following:
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.
Backup your computer in some way. Use Time Machine or use Disk Utility's Restore option to clone your HDD:
Clone using Restore Option of Disk Utility
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
2. Lion will most certainly run on your computer. Requirements are a Core 2 Duo or better, 2 GBs of installed RAM, and 8-10 GBs of free space on the hard drive.

I try to update and backup data from iphone to iMac but keep fail

Hi, I have problem with updating and backup my iphone to imac. If you can help me about my problem that will be great.

Hello jennywijaya,
I would be concerned too if I was not able to backup my iPhone. I recommend the following article for troubleshooting backup issues with iTunes:

Software update and iLife help not working in Admin account

For the last few weeks (maybe since iLife 11 was installed) software update and iLife help has quit working on the single administration account on my iMac. All works fine on the secondary accounts.
If I try to use software update it says everything is up to date, even though I know there are updates available that can be seen if checking from a different account on the machine. In iLife, if I try to access the help files it tells me I need to download them. I click to download and after a few seconds it takes me back to the front help page and I then go through the entire process again but the help download never happens. On secondary accounts the help files work no problem.
I've tried many of the tips for deleting helpfile plists, but nothing seems to work for me.
Can any kind person list for me everything I should look to delete or move in the account to get these things working again?
It would be much appreciated!

Since the issue is specific to your original user account, you can proceed in two ways. One is to log into your new account, make a list of the preference files (plists) located in /username/Library/Preferences/, including any in the ByHost subfolder, log back into the original account, move everything on that other account's list from the original account's Preferences folder into a newly created folder on the Desktop, log out and back in, and see if the problem goes away. If so, you can copy the ones in the Desktop folder (one at time) back into /Preferences/, restart, and see if the problem returns. If so, you've identified the corrupt/conflicting one. Continue with all of them until isolating the bad ones. That'll save you the trouble of resetting preferences.
The second way is much more detailed and I'll not burden you with the steps unless the above doesn't fix the issue.

By install i presume you mean add it to the bottom of the machine ?
Yes, and it's rather easy to do too.
Your machine has two slots. These are the specs for a 2008 iMac (if your machine is different then check with Crucial.com and they will match the correct RAM for your machine)
Maximum Memory
6.0 GB (Actual) 4.0 GB (Apple)
Memory Slots
2 - 200-pin PC2-6400 (800MHz) DDR2 SO-DIMM
So all you need to do is visit Crucial.com or OtherWorld Computing to order it, and OtherWorld Computing has install videos.
Here is one on YouTube. Easy pleasy.
Just make sure to discharge any static electricity and not touch the contacts, just the plastic edges.

I went to back up my iPhone4 and it said there was an update. So I clicked on 'update and backup' (or something close to that.) It took FOREVER...way longer than usual. When it was done, it showed the power cord w/an arrow to iTunes. ***??? I restarted my computer and tried the whole process again and still...the power cord with an arrow to iTunes. And I know this means I have to go to Apple and get another phone and will lose anything that wasn't backed up. Anyone else have this happen or have a solution so I don't have to do a restore???

Reboot your computer.
Disable your antivirus and firewall.
Connect the phone to a USB port directly on your computer, not to a hub. If your computer is not a laptop and has ports on both front and back use a port on the back.
If iTunes does not recognize the phone when you connect it see: http://support.apple.com/kb/HT1808
If it STILL doesn't work open a command window and type:
netsh winsock reset
Then try again. (It seems that a recent Microsoft Windows update may have corrupted network settings; this restores them to the factory default).
BTW, was there an error number associated with the failed update?

This update doesn't work! I'm at 10.5.8 on my old iMac G5, installed the update and brightness and volume just do not work. What next?

I have a brand new wireless keyboard... so it's never going to work. BUT... I found a sort of work round!
Since it's eyeTV that I want to control the volume more than the system volume I discovered cmd and up/down arrows do the job. I gess I'll forgo the brightness function.
I'm a little frustrated that it appears Apple seems to want to push me towards an upgrade of a perfectly serviceable iMac G5. I'll be keeping it to watch TV, surf the web, wordprocess and let the macbook pro handle photos & video.

Can I install windows 7 on my portable HDD from my Mountain lion? and how i need to do it?

Can I Install Windows 7 on my portable HDD from Mountain lion ? And how i need to do it?

Welcome to the Apple Support Communities
Because of a Microsoft restriction, Windows can't be installed on an external drive (there are workarounds, but you need Windows). Apart from that, Boot Camp only works with the hard drive where you have installed OS X, so you can't use it to install Windows on an external drive

Mountain Lion update, and now computer won't start up?

Writing this for a friend, as his computer is inop at the moment. Hence this message.
He has a new 27" iMac. He upgraded to Mountain Lion a few weeks ago, and then had intermittent problems with apps unexpectantly shutting down.
Now he did a ML update this morning, and his computer won't start up. It gets to the point of the Apple logo coming up, a progress bar, and then the spinning wheel, but then shuts itself down right afterwards.
A safe boot yields the exact same result.
Any thoughts out there on what he could try to get it up and running again?
Thanks much for any and all help.

Thank you for the fast response.
He was able to get into Disk Utility with the Command and R keys, but when he tried verifying the disk, in red it said 'Invalid Node Structure, volume could not be verified completely'.
He went ahead and verified it anyway, then proceeded to repair it. Howver, it stopped repairing, said it cannot repair, and that he should back up files and reformat the disk.
How can he back up his files? He cannot see a way to do it. Is there anything else he can do besides having to reformat the disk?
This is his first Mac (after much prompting from me to go Mac), and he's afraid he's now lost everything on there.

IMac freezing since lion update

Itunes update and automatic update of ipod help needed

i just upgraded to the newest version of itunes (6.4?), and i deleted some songs out of my library and it gave me a message to the effect that next those files would be removed from my ipod next time i connected it.
i know in the previous version of itunes that i had, i had shut off the option that automatically updates your ipod when you plug it in, so i tried to find that option on here and was unable to, i think it might show up after i plug in my ipod, but obviously i dont want to plug in my ipod until i know it isnt going to get erased, anyone know if i can connect my ipod safely of if i need to change something, and if i need to change something where i would find that control. thanks in advance for any help

You can use a keyboard command to prevent your iPod auto-syncing with iTunes. While connecting the iPod to the computer hold down the Shift + Ctrl keys (on a Mac hold down the Option and Command (⌥ and ⌘) keys). This will stop the iPod from auto-syncing with iTunes and the iPod will appear in the source list. Wait until you are sure the iPod has mounted, and that it will not auto sync and then you can let the keys go. This may take between 3 and 30 seconds depending on your computer. Then go to Preferences>iPod and check the "Manually manage songs and playlists" box.
If at any stage iTunes brings up a dialogue window asking whether you want to replace the songs on your iPod with the songs in iTunes, press *No*.

Problem to pass through firmware update... help needed !

Hi there !
having trust in Apple has run software update on blind date basis, ie, just pressed the button to update everything what was proposed .
i did not have a look, what was proposed to update, unfortunately ...
apparently, some firmware update have been loaded and started by default... my lovely mac book pro restarted with grey screen and progress bar
which looks as usually available only while it's updating firmaware . It took one try, did not work out, tried once again and then just switched mac down.
i've tried to restart it once again, unfortunately it always the same story, ie two tries and then shot down.
i was trying to look on the net for some information , what sort of firmware update Apple proposed recently, and what kind of trouble i could run into,
but no information related to my case available.
can anybody help me, how can i fix the problem ?? any shortcuts, to stop this update and return back to onld firmware ??
i just can't boot my computer normally, cause its bump into this update once and once again and fails to go through it..
thank you in advance,
Vladimir

Disk configuration and workflow help needed for lab video workstation

Hi All,
Setting up a video editing workstation for a research lab that will use Premeire to edit AVCHD Progressive clips (sometimes with 2 streams side-by-side, but usually single-camera) and export them to .mp4 for later viewing by video coders. We won't be using AfterEffects or adding anything to the videos other than some text (titles, maybe sub-titles).
The other purpose of this workstation is to act as a file server and backup system for other machines in the lab. Coders will be viewing the exported videos via other networked machines and working with Microsoft Office files that will be stored on the workstation's other HDDs. I'll have a physical backup drive and cloud backup via CrashPlan.
I've built a machine that is probably overkill, but the client (my wife) wanted it to be "fast," and the purpose of the machine might change in the future:
i7-4770K (overclocked a bit)
16GB RAM
Asus Z87-Pro
GeForce GTX 660
I have the OS (W7) and programs on a 256 GB Samsung 840 Pro SSD and currently have two 1TB Velociraptors to use for the Premiere workflow. I'm trying to figure out how to proceed with the purchase of the rest of the drives, and I want to keep the Premiere drives separate from the large storage drives from the lab that are networked and synced to cloud backup.
Following the recommendations for a three-disc configuration I've picked up on these forums, I could set it up like this:
C: (256GB SSD) (OS, programs, pagefile)
D: (1TB HDD) (media, projects)
E: (1TB HDD) (previews, media cache, exports)
F: (4TB HDD) (backups of media, projects, and exports and storage of other research files)*THIS DRIVE WOULD BE SHARED ON THE NETWORK
G: (4TB external HDD) (backup of F & drive that backs up to CrashPlan)
but it seems that would be a waste of the speed of the second 10k velociraptor. If I added another SSD and RAIDed the Velociraptors it would be:
C: (256GB SSD) (OS, programs)
D: (Two 1TB Velociraptors in RAID 0) (media, projects)
E: (256GB SSD) (media cache, pagefile)
but would I then need to add another dedicated HDD for previews and exports, or could I store those on the networked F: from above (which would be previews, exports, backups of media and projects, and storage of other research files) without taking a speed hit?
It seems overkill to have a dedicated drive for exports and previews (let's make that the new F:), then have them copy to the first 4TB drive (now G:), then back that up to the second 4TB drive (now H:), then back that up to CrashPlan. However, people might be accessing that network drive at any time, and I don't want that to slow any part of the video process down.
I appreciate any advice ya'll can give me!

Hi Jim,
Thanks for the encouraging response. I'm leaning toward the non-SSD option at this point.
To make sure I understand, are you suggesting I try using the Velociraptor Raid 0 in the 2 disk configuration suggested by Harm's Guidelines for Disk Usage chart? Like this:
C: (256 GB SSD) (OS, Programs, Pagefile, Media Cache)
D: (1TB x2 in RAID 0) (Media, Projects, Previews, Exports)?
Where I'm still confused there, and in looking at Harm's array suggestions for 5 or more drives, is how performance is affected by having simultaneous read/write operations happening on the same drive, which is what I understood was the reason for spreading out the files on multiple drives. Maybe I don't understand how Premiere's file operations work in practice, or maybe I don't understand RAID 0 well enough.
In the type of editing we'll be doing (minimal) aren't there still times when Premiere will be trying to read and write from the D: drive at the same time, for example during export? Wouldn't the increased speed benefits of RAID 0 for either read or write alone be defeated by asking the array to do both simultaneously?
Maybe the reason the Media Cache is on the SSD in the above configuration is because that is what will be read while writing to something like Exports? But that wouldn't make sense given Harm's chart, which has the Media Cache also located on the array....
Another question is, given that the final home of the exported videos will be on the big internal drive (4TB) anyway, could I set it up like this:
C: (SSD) (OS, Programs, Pagefile, Media Cache)
D: (2TB RAID 0) (Media, Projects, Previews)
E: (network shared 4TB HDD) (Exports + a bunch of other shared non-video files)
so I don't end up having to copy the exported videos over to the 4TB drive? Do you think it would render significantly faster to the RAID than it would to the 7200 rpm 4TB drive? I'd like to cut out the step of copying exported videos from D: to E: all the time if it wasn't necessary.
Thanks again.

[Mostly Sorted] Extracting tags - regexp_substr and count help needed!

My original query got sorted, but additional regexp_substr and count help is required further on down!
Hi,
I have a table on a 10.2.0.3 database which contains a clob field (sql_stmt), with contents that look something like:
SELECT <COB_DATE>, col2, .... coln
FROM   tab1, tab2, ...., tabn
WHERE tab1.run_id = <RUNID>
AND    tab2.other_col = '<OTHER TAG>'(That's a highly simplified sql_stmt example, of course - if they were all that small we'd not be needing a clob field!).
I wanted to extract all the tags from the sql_stmt field for a given row, so I can get my (well not "mine" - I'd never have designed something like this, but hey, it works, sorta, and I'm improving it as and where I can!) pl/sql to replace the tags with the correct values. A tag is anything that's in triangular brackets (eg. <RUNID> from the above example)
So, I did this:
SELECT     SUBSTR (sql_stmt,
                   INSTR (sql_stmt, '<', 1, LEVEL),
                   INSTR (substr(sql_stmt, INSTR (sql_stmt, '<', 1, LEVEL)), '>', 1, 1)
                   ) tag
FROM       export_jobs
WHERE      exp_id = p_exp_id
CONNECT BY LEVEL <= (LENGTH (sql_stmt) - LENGTH (REPLACE (sql_stmt, '<')))Which I thought would be fine (having tested it on a text column). However, it runs very poorly against a clob column, for some reason (probably doesn't like the substr, instr, etc on the clob, at a guess) - the waits show "direct path read".
When I cast the sql_stmt as a varchar2 like so:
with my_tab as (select cast(substr(sql_stmt, instr(sql_stmt, '<', 1), instr(sql_stmt, '>', -1) - instr(sql_stmt, '<', 1) + 1) as varchar2(4000)) sql_stmt
                from export_jobs
                WHERE      exp_id = p_exp_id)
SELECT     SUBSTR (sql_stmt,
                   INSTR (sql_stmt, '<', 1, LEVEL),
                   INSTR (substr(sql_stmt, INSTR (sql_stmt, '<', 1, LEVEL)), '>', 1, 1)
                   ) tag
FROM       my_tab
CONNECT BY LEVEL <= (LENGTH (sql_stmt) - LENGTH (REPLACE (sql_stmt, '<')))it runs blisteringly fast in comparison, except when the substr'd sql_stmt is over 4000 chars, of course! Using dbms_lob instr and substr etc doesn't help either.
So, I thought maybe I could find an xml related method, and from this link:get xml node name in loop , I tried:
select t.column_value.getrootelement() node
from (select sql_stmt xml from export_jobs where exp_id = 28) xml,
table (xmlsequence(xml.xml.extract('//*'))) tBut I get this error: ORA-22806: not an object or REF. (It might not be the way to go after all, as it's not proper xml, being as there are no corresponding close tags, but I was trying to think outside the box. I've not needed to use xml stuff before, so I'm a bit clueless about it, really!)
I tried casting sql_stmt into an xmltype, but I got: ORA-22907: invalid CAST to a type that is not a nested table or VARRAY
Is anyone able to suggest a better method of trying to extract my tags from the clob column, please?
