Have I done a really stupid thing?
Hi
On a whim, I recently purchased a 20" Apple Cinema Display on ebay. Whilst the listing said it was faulty owing to a damaged power supply - that had been 'professionally repaired' - I thought it would be a good buy and I could get the problem diagnosed and hopefully just replace the power supply.
I won the auction and paid just £100 ($190) so I thought, even if I bought a new power supply, I would have a bargain.
The display arrived this morning and, apart from a few cosmetic marks on the casing, it's in pretty good condition, the LCD is unmarked. However, the 'professional repair' of the power supply looks to be a joke and the power adapter has been replaced with a very cheap looking black plastic box. In addition the DVI(?) connector appears to have been dismantled and put back together with sellotape!
I was under the impression that the power supply can simply be unplugged from the back of the display - a la my iMac - so I could test it using the power supply on a colleague's display in work, but this does not appear possible? (well, not easily anyway).
So, getting to the point, has anyone ever replaced the power supply on an ACD and how much did it cost? Also, I was expecting there to be a plug for a wall power outlet? Does the screen just connect to the DVI output on my powerbook? Do I need to plug in any of the USB/FW connections?
I realise I have been a bit naive buying 'sight unseen' but as I say it was on a whim - I don't even have a use for the display in mind at the moment. I'm usually the first person to say if something looks too good to be true it probably is, but I hope I haven't bought a complete waste of aluminium!
Be gentle with me - I hope someone can reassure me it can be repaired.
Many Thanks
Tim

Yes unfortunately the cable to the display is not detachable, It would be very convenient but would also make for a very complex connector to accommodate DVI, USB, FIreWire and Power all at once !!
I'm sure your actual display is ok... provided that cheap sounding power transformer hasn't fried it.
The cables of a new cinema display look like this:
http://images.apple.com/displays/images/designsidebarcable20060721.png
from left to right: DVI, USB, FIreWire and Power on the far right.
The Power connector is Apple's proprietary connection and plugs into the power transformer, which in turn plugs into the mains.
So yes you should have a plug for a power outlet... (DVI doesn't power it). The USB and FireWire connectors don't have to be plugged in ... they just connect to the display to act as a hub with the ports on the back of the display... all that is required is the DVI and for the DIsplay to be powered.
I wouldn't recommend using whatever power transformer they have given you... if you can i would recommend trying to find an original power brick from apple... does the power cable still have the apple connector or have they stripped it to fit their adapter?
If the DVI connector looks that bad then you could get a new one and replace it yourself if your handy with the soldiering iron, just make sure you label the wires because theres a fair few. Or you might just want to open it up to check it's intact inside then seal it properly.

I've done something really stupid.....
.... I've put some files in to .dmg image and password protected the file..... now I've forgotten the password!! Is there any way to break into it, or do I have to do all the work again (sob sob)!
Thanks,
AndyIf you unchecked the 'remember password in keychain' option when creating the dmg, than there is no other way to get the password back. If you have Time Machine, than the 'doing it again' process will be MUCH faster. Just restore the files back to when you didn't have them on a dmg.
That is the problem with password protecting folders.

H E L P ! I did a really stupid thing....
I downloaded some of these extensions apple had on their web site yesterday to my iMac and they created an inch wide toolbar which is NOT what I wanted. I would like to delete these extensions but I can't find them anywhere. I've looked in my downloads and my application files, as well as my documents. I called apple support and they couldn't help me either. Please, is their anyone out there that can help me?
Hi,
If you installed apps from the Mac App Store just go to your Applications folder and move them to the Trash.
If you are referring to Safari Extensions, that's something else.
From your Safari menu bar click Safari / Preferences then select the Extensions tab. You can uninstall Extensions from there.

Hi, I have recently done some online updates and now I have to restart my mac each time for the stupid thing to recognise my internet settings. Any help gratefully accepted.
Please be specific about the updates.
Were they Apple updates from Software Update or were they downloaded updates, including 3rd party updates from a website (Including Apple's)? -
I have 2 apps that have been waiting to update for a week. I don't really care about the update, I would just like to use them, but the are stuck waiting. I have tried powering down, syncing with my computer...all fails. Any ideas?
At this point you have no choice but to update the or delete them and reinstall them since you wont be able to use them until they update - or come out of the "waiting" loop.
Make sure that you do not have a stalled download in iTunes - a song or podcast .... if you have a download in there that did not finish, complete that one first. Only one thing can download at a time on the iPad so that could be what is causing the problem.
If that doesn't work - sign out of your account, restart the iPad and then sign in again.
Settings>Store>Apple ID. Tap your ID and sign out. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Go back to Settings>Store>Sign in and then try to update again. Tap one waiting icon only if necessary to start the download stream.
You can also try deleting the waiting icons - tap and hold down on an icon until it wiggles - the tap the X on the icon to delete it. Then try to download again.
You can try resetting all settings. Settings>General>Reset>Reset All Settings. You will have to enter all of your app preferences and device settings again. -
So how do I get notified of updates in this forum? As I said: I don't understand the thing you call LIVE BOOKMARKS I have never used them, and most forums I have used notify VIA E-mail not giving out my E-mail address, or other private information when a reply has been made to the thread in question, so how do I get notified of updates in this forum? I have seen no normal options for setting my viewing preferences used for this forum. Thank You.
Thanks for your reply via email/msg. He wrote:
If you are interested in the actual design data for the Xeon processor, go to the Intel site and the actual CPU part numbers are:
Xeon 4 core - E5.1620v2
Xeon 6 core - E5.1650v2
Xeon 8 core - E5.1680v2
Xeon 12 core - E5.2697v2
I read that the CPU is easy to swap out but am sure something goes wrong at a certain point - even if solderedon they make material to absorb the solder, making your work area VERY clean.
My Question now is this, get an 8 core, then replace with 2 3.7 QUAD CHIPS, what would happen?
I also noticed that the 8 core Mac Pro is 3.0 when in fact they do have a 3.4 8 core chip, so 2 =16? Or if correct, wouldn't you be able to replace a QUAD CHIP WITH THAT?

SOMETHINGS UP AND AM SURE WE'LL ALL BE PLEASED, AS the mac pro was announced Last year, barely made the December mark, then pushed to January, then February and now April.
Would rather wait and have it done correct than released to early only to have it benchmarked in audio and found to be slower in a few areas- - - the logical part of my brain is wondering what else I would have to swap out as I am sure it would run, and fine for a while, then, poof....

I have a macbook pro mid 2010 17'' 2.66 i7 looking to put a new hard drive in it something like a 250 gb , orig drive 500 gb 5400 toshiba but i don;t really need that much space so i would like some input, type,speed,brand,compatibly,noise Thank You!!
There's no reason to install a smaller hard drive. In some cases, it may decrease performance.
Your MacBook Pro comes with a 5400 rpm hard drive, so what you can do is to install a smaller, 7200 rpm hard drive, so you will get a better performance. Any 2'5" SATA hard drive will work, but you can have a look at OWC for hard drives > http://eshop.macsales.com/shop/hard-drives/2.5-Notebook/
HGST and Seagate hard drives have a good reputation, so you can purchase one of them -
Is it possible for the Adobe to put video instructions on these following things as my professor works on CS4 and I have CS6,it is really confusing for me to follow the disparitie between the two
Modifying the header
Changing page background color
Changing sidebars in CSS
Adding/changing a Spry link's background and hover colors in navbar
Formatting headers in split view
Deleting placeholder copy in the content container
Inserting a video in a table
Changing table background color
Formatting text in the content container
Format hyperlinks in CSS
Insert page anchors and link to them with navbar hyperlinks
Enter text in footer with a hyperlink
Insert and format headers
Use of a color picker (Color Cop)Use CS6 Help (F1). Those are the most up to date articles for your product version.
<Changing page background color>
We've already told you how to do that with CSS code.
<Deleting placeholder copy in the content container>
Placeholders are deprecated. Adobe removed them.
<Inserting a video in a table>
Insert > Media > HTML5 Video
<Insert page anchors and link to them with navbar hyperlinks>
Named anchors are deprecated in HTML. Adobe removed them from DW. Use Div IDs instead.
Why are you taking a course that teaches outdated methods in CS4 which is no longer supported?

I have an old file with an .A4P video from 1999. I don't own any Adobe products (and don't really want to buy any). I just want to be able to convert the file to something that I can actually view. Any help?
I was a kid when I made a documentary for a school project. I've been trying to figure out how to retrieve the file. 4 years ago, I was able to get the files off the Iomega Zip drive (finally), but I now see the file is saved as a .A4P. There is also a file saved as a .PKG as well, but I don't know how to open this with my Windows 8 COmputer..a4p is an Authorware v.4 (Windows) project.
Interesting you have it as a .pkg...usually that's a published-on-a- Mac extension, if I recall.
At any rate, can you put the file up on a Box, Dropbox, FTP, etc...and send me a URL?
I should be able to published it so you can view the project (it would be an .exe).
It can't be converted to anything though - not without manual effort. -
i have a ipod touch 4gen and whenever i sync it, i just lose all my memory... and im also trying to restore my memory but don't really know how... how do i do it?
Only sync chosen songs. Even with that I had a bad song once that was corrupted and it blew the ipod touch's mind. Can't remember how I found the song, but deleted it off the computer and was able to get a fresh copy off this quite old CD. Also, settings-general-usage, you can see which files are gathering up in your memory. There are some surprisingly large programs.

Is there a way to color one thing in a black and white photo. Example: I have a picture of a tulip field and I want to make it black and white - which I have already done - but I want to make one single tulip red. Help?
No, you'll need an external editor for the job:
In order of price here are some suggestions:
Seashore (free)
The Gimp (free)
Graphic Coverter ($45 approx)
Acorn ($50 approx)
Pixelmator ($50 approx)
Photoshop Elements ($75 approx)
There are many, many other options. Search on MacUpdate. You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. This is the only way that edits made in another application will be displayed in iPhoto. -
Hi, I have been trying to update many things on my 2009 white macbook. Everytime I do it tells me I need a different version. I don't know what versions I need or even where to begin or if I need to purchase new hardware? It says my version is 10.5.8. I have tried downloading 10.6 but not sure what to do. Everyone else seems to be updating there's and mine is way behind however it still tells me I have no software updates...Any suggestions?
You have to understand the difference between an Update and an Upgrade.
An Update is a free change to add to the base code or as a bug fix within an existing Operating System. Such as the .8 added to 10.5.
An Upgrade is a complete new Operating System that must be purchased. Such as 10.5 Leopard to 10.6 Snow Leopard.
10.5 Leopard was based on Power PC code and was written to be able to run on both Power PC and Intel processors.
10.6 Snow Leopard has completely rewritten code and only runs on Intel Macs.
10.7 Lion used some 32 bit which allows it to run on Late 2006 through Early 2008 MacBooks and a lot of 64 bit code.
10.8 Mountain Lion is pure 64 bit, which excludes more systems than Lion did. It's not something you can add memory to, for example, as it involves the base architecture. -
Hi I have done all the right things to set up the home sharing, turned it on, aurthorised it with the same details, but we still have not got the home icon in the menu to select. can anyone help?
If you have iTunes 11 on your computer then you can enable the left-hand sidebar on it via option-command-S on a Mac, control-S on a PC - when connected (and if your computer's iTunes is up-to-date) your iPad should then appear on that sidebar under a 'Devices' heading :
If you select the iPad on that sidebar you can then use the Movies tab on the right-hand side of the iTunes screen to select and sync that film to your iPad's Videos app.
Has your iPad been synced to the computer before ? If not then you might find this page for syncing to a new computer useful : https://discussions.apple.com/docs/DOC-3141 -

After updating to ios 5, my calendar sometimes freezes when entering a new event. I have tried syncing but it doesn't fix the problem. Are there any bug fixes for this? Any ideas would be great thanks, I don't really want to have to reset everything!
Try to reset the iPod by pressing the home and sleep button for about 10sec, until the Apple logo comes back again. You will not lose data doing a reset, but it can clear some glitches after installing new software or apps.
