I can't open my computer

I have a intel-based imac... I want to change the memory but I can't open it... I don't know if i am doing something wrong or what?... the screw is turning and turning but it just don't open... what can i do?

Welcome to Apple Discussions.
The screw is the type that will loosen but not fully come out. Once it's fully loosened use a small screw drivers to pop the door off. Here is an installation video to make it a little easier.
Regards,
Roger

How can i open "my computer" in java

How can i open ]my computer[b in java

Two options:
1) Execute
Runtime.getRuntime().exec("explorer.exe ::{20D04FE0-3AEA-1069-A2D8-08002B30309D}");2) Look at javax.swing.JFileChooser
The first option will do what you want, but it is specific to Windows only (I tested it on XP, I don't know if it'll work on other versions). The second is cross-platform, but won't give you the same view as a native explorer.

You need to supply much more information than that.
What, exactly, are you trying to do?
What, exactly, do you do to make it happen?
What happens when you do that?
What doesn't happen that you expected to happen?
What model of Mac is it? (e.g. 2006 iMac; 2010 MacBook Pro). What OS are you running - Mavericks, Mountain Lion, etc?
When did it stop working? What had you done prior to that?
Are you saying that when you turn on the computer, you don't get the Finder, your desktop and all your files, but the computer just remains at a blank screen?
Or are you talking about your web browser, displaying a blank document window?

New Macs have not shipped with iWeb for over 2 years and Apple has not sold or supported iWeb for at least 2 years now - Apple stopped selling it and dropped support for it when MobileMe was ditched in favour of iCloud which does not offer hosting.
If you want iWeb, then you will need to have a look at your old installation CD's for your old Mac and see if iWeb is on these and you can then install it from there or if you don't have these CD's any longer, then you'll have no option but to purchase a copy of either iLife 09 or iLife 11 from Amazon - these boxed sets both contain iWeb 09, which is the latest version of iWeb.
Other than this and as you have not done your blog for sometime, perhaps you should consider re-creating it from scratch with a software that is actively supported and updated - that is NOT iWeb any longer.
You could try using WordPress, either .com or .org - .org is good if you already have hosting and you can install WordPress directly onto your server. If you want something free, then you could use WordPress.com which is then published on the WordPress servers.
You could also take a look at EverWeb from Rage Software, which is very new and is very like iWeb with all the extras, such as drop down menus etc. Take a look at http://www.everwebapp.com.
As for your files, it sounds that when you say files, these might be the published files for your site, if you went into iWeb and published them to a local folder? This is not a backup and even if you could find these files, then iWeb will not be able to open them because it has no import facility, so cannot open an already published site - html and css files.
What you need is your domain.sites files which can be found under your User Library/Application Support/iWeb/domain.sites.
I would cut your losses and if you don't have iWeb, then don't bother paying for software that is now outdated and unsupported - move onto to something new and re-create everything in either WordPress or EverWeb.

Can't open Firefox, computer thinks it is already open

just got a new iMac, and wanted to transfer all my old Firefox info from my old machine. I downloaded the newest version of Firefox, and it seemed to work fine. Then I tried to move my profiles to the new machine (both on same network). Then I don't know what happened. I had to close Firefox for some reason, and when I tried to reopen it was told by my Mac that "A copy of Firefox is already open. Only one copy of Firefox can be open at a time". I checked in Finder to see if I could force-quit Firefox, but according to Finder firefox was NOT running.
I first did a restart of the computer, but when I tried to open Firefox got the same message. Then I threw my Firefox application away and downloaded a new one. No help, same error message.
So how do I convince my Mac that Firefox isn't already running? Help, please!!!

Installed a security update and can not open my computer. Will not accept my password

Installed an update and cannot open my computer. Will not accept my password. Running mountain lion. Have not used the login screen since I bought the computer, but now it pops up when I turn it on and i can't get by it.

A Safe Mode boot may help ...
Startup your Mac in Safe Mode
A Safe Mode boot takes longer than a normal boot so be patient.
Once you are in Safe Mode, click Restart from the Apple () menu.

HT1926 I was loading an update to my i-Tunes for my computer and got an error message and now I can not open my computer itunes and may have lost all the content. What do I do?

I got a request from apple to update my itunes and while uploading the update, the program gave an error message and now I can not open my itunes and fear that all my music etc is gone? what do I do to correct this problem?

Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall move on to the next item)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.

HT1923: Removing and reinstalling iTunes for Windows Vista, Windows 7, or Windows 8

I can't open my computer. When I type in the password an extra arrow appears facing upwards (the other one facing to the RHS) If I press either nothing happens there is a cancel button as well (which i don't need) HELP!?

I cannot open my computer> When I type in my password an extra arrow appears (facing upwards) If I press either the usual arrow (facing RHS) or the new one nothing happens.
A cancel button below the password is also present
I am getting desperate
Any ideas
Thanks

Check that your Caps lock isn't on. Maybe the light that indicates whether it is or not has stopped working. Anyway, try pressing it see if it helps.

Can't open folders/explorer after sleep or hibernation

I recently started to have this problem where when the laptop is woken up after either a sleep/hibernation, I can't open any folders. I can't open the computer icon, any folders on my desktop and the Windows File Explorer. I can, however, open the files (Excel, IE, Firefox) on the desktop even when this problem comes up.
It doesn't happen every time the laptop is woken up from either state but happens at least every other day.
In order resolve the issue, I have to restart the computer or log out and re-login.
I thought I had some corrupt files so I re-imaged the HD to its original state, but the problem came back.
Any thoughts or suggestions???
I have X230 with Windows 7 64bit
Thanks.

This worked for me: I trashed my mouse prefs, then restarted, then -- goto System Prefs --> Keyboard/Mouse --> Mouse --> Double-Click Speed: Now move the speed a minimum of one notch below FAST.
Yesterday I installed a Logitech MX Revolution, cordless mouse and lost the ability to double click with it and with my Mighty Mouse. Resetting the double click speed below FAST miraculously reset.
All seems OK now.

When I use the new Pages on my iPad, I can't open it on my new computer. It tells me that I must download the new Pages to see the Pages document, but when I try to download the new pages to my computer it tells me all apps are up to date.

When I use the new Pages app. On my IPod to type documents, I can't open them on my new computer. It sends me a message that I have to download a newer version of pages to see the Pages document. When I try to do that it tells me all my apps are up to date and will not allow me to upgrade the pages on my iMac.
Any suggestions?

Iweb installed on a new computer but i have this error message: Can't open file "~/Library/Application Support/iWeb/Domain.sites2."

I have just installed ilife on my new computer from my disk. I have several backups of my webpage from my old computer. Everything would be great if I could just run the program. When I click the icon for iWeb I get the following message: Can’t open file “~/Library/Application Support/iWeb/Domain.sites2.”
Somebody please help! I desperately need to update my website.

In Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
To open your domain file in Lion or to switch between multiple domain files Cyclosaurus has provided us with the following script that you can make into an Applescript application with Script Editor. Open Script Editor, copy and paste the script below into Script Editor's window and save as an application.
do shell script "/usr/bin/defaults write com.apple.iWeb iWebDefaultsDocumentPath -boolean no"delay 1
tell application "iWeb" to activate
Just launch the application, find and select the domain file you want to open and it will open with iWeb. It modifies the iWeb preference file each time it's launched so one can switch between domain files.
You can download an already compiled version with this link: iWeb Switch Domain.
WARNING: iWeb Switch Domain will overwrite an existing Domain.sites2 file if you select to create a new domain in the same folder. So rename your domain files once they've been created to something other than the default name.

HT5361 I can't shut down my computer because it says mail is open. It says to close mail and continue shut down. Problem is I can't open or close mail now. Can't shut down my computer at all. What can I do?

I can't shut down my computer because it says mail is open. It says to close mail and continue shut down. Problem is I can't open or close mail now. Can't shut down my computer at all. What can I do?

If you cannot get mail to quit/force quit, you can always remove power from your Mac.
NOTE: removing power is a bad idea, and can result in data loss, but sometimes it is the only thing left to do.
Press and hold the power button for 5 to 10 seconds, and the Mac will power off.
When you power back on, the Mac should reboot.

Hello all.   Hope someone can help me. I recently downloaded some updates for my imac. Since doing this the computer starts up but I get no logon box. The home screen opens but I can't open any programs or files. I've tried rebooting, no joy. Help!!

Hello all..   I hope someone here can help. I recently downloaded some updates to my imac. Since then the computer starts but I get the home screen opening without the logon box.    I can't open any programs or files and if I click on the Safari tab it disappears from the dock. I've tried rebooting with no joy.
I contacted technical help at Apple and was told to hold down the ctrl and alt keys with two other keys, I think the S or P keys when powering up. This worked
and the computer seemed fine but now the problem has reappeared. Is there a way to removed downloaded updates from the computer or revert it to an earlier state?   Sorry for the long question. Hopefully one of you clever people can help.   Simon

I have a hard drive icon on my desktop that says 10.6.2....
I use to have iphoto, it doesnt open anymore, it says there is 1.2gigs on that disk.There are many things on here that are the same way. Where do I start?
It's always good to go with one thing at a time and stay focused on that. Let's start with the OS you're running. Click on the Apple menu > About This Mac. What does it say under Mac OS X version ?
