Do I have to delete Maverick before I can install Yosemite when is is released?

Can some one tell me if I have to delete Maverick from my computer before I can install the new Yosemite when it is released? Thanks

Not sure if you are asking about the steps in the installation process or if you are wondering whether you can have both on your computer at the same time.
Previous upgrades that I have done don't require deletion of the older operating system before installing the new one but the new one replaces the older one. There may be a way to have both that someone else can help you with if that is what you are asking.

Do I have to have OS X Mavericks before I can download Yosemite?

I have a Mac Book and recently tried to upgrade to Yosemite and after 3 days of downloading it said that it could not. There was sufficient memory on my laptop so not sure why it would not download.

How much hard drive space is free? You need 8 GB or more of available space.

Can anyone help me find my old library now that I appear to have deleted it or overwritten it accidentally? I'm always asked if I want to update when I put in my i-pod and have to do that before I can open my library so I think it was this action.

I'm always asked if I want to update when I put in my i-pod and have to do that before I can open my library so I think it was this action that caused me to delete previous library. Can anyone help? Apple support have been hopeless as they don't seem to respond to this particular problem but keep giving me answers to finding my purchases which i already know how to do!

Photos on iPad and iPhone as Events that i have already deleted in iPhoto and can't find out how to delete?!

Photos on iPad and iPhone as Events that i have already deleted in iPhoto and can't find out how to delete?!

I had an album on my iPad that didn't have a delete option. I was able to finally remove everything by connecting the iPad to iTunes and going to the Photos tab. Select sync photos. It will ask you if you want to replace all photo on iPad with sync photos. Apply the setting and then un-sync photo again. It will then remove all photos on iPad starting with a clean slate.
Be sure to backup all your photos before doing this. Hope that helps.

Turn your phone off and connect your cable to the computer, but not the device just yet. Start up iTunes. Now, hold down the home button on your phone and plug it in to the cable - don't let go of the button until iTunes tells you it's detected a phone in recovery mode. Now you can restore to factory settings.

When I hit tab on a form I get message "at least 2 windows have to be opened before you can merge them"

It seems that anytime I hit the tab key on a web page with a form, like to move the cursor between first name and last name for example a message appears at the top of the web page display area that says "at least 2 windows have to be opened before you can merge them".
I have to assume this is the result of an add-on or option change I've made but I cannot find it. If anyone has any idea what might be causing this behavior I would really appreciate any help resolving it.

Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe Mode start window.
*https://support.mozilla.org/kb/Safe+Mode
*https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
If it works in Safe Mode and in normal mode with all extensions (Firefox/Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)

When I click and open my Firefox browser ,it always opens to Firefox welcome page ,NOT my google search page , which is my home page , how can I fix this , I have to always have to close FF before I can search !!??

Can you help me figure out how to stop Firefox from opening to welcome page / updated window, I have to close that before I can use my google search page ,which is my homepage !!

You can start by checking the Home page setting to see if that still links to the Google Home page (http://www.google.com/firefox)
* Tools > Options > General > Startup: Home page
You can also check the startup setting just above the home page setting.
If the home page setting isn't correct and changing it doesn't last if you close and reopen Firefox then you need to check if the file [http://kb.mozillazine.org/prefs.js_file prefs.js] in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder] isn't corrupted.
* Help > Troubleshooting Information > Profile Directory > Open Containing folder

You do. Your system is either Windows or Mac (or maybe a couple of other less popular choices) and a version of one or the other.
When you set up your machine, you were asked for an administrator user name and password. You need both of these to install software.

Every time I turn on my laptop about half a dozen previous documents open up and I have to close them before I can begin. Can anyone help me prevent this from happening as it's driving me nuts!

First thing to (un)check:
When you shutdown/restart, there's a dialog box which confirms your request. In that box is a little checkbox which you should uncheck.

Updated to IOS6 and now my apps will not update on the Ipad2. I have to delete them and then re-install. But I have several hundred apps and this is cumbersome. Seems the new software is too buggy. I am telling people not to update software yet.

Basic troubleshooting from the Users Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.
