How do I know what OS I have on my iMac? I've used it as a PC for years and need to switch over but I may be out of date with current software.  I think I read Lion somewehere....?  OS 10.5.8

Click on the Apple icon at the top left of your menu bar, then About this Mac.
OS 10.5.8 is Leopard. Lion is 10.7
As for upgrading:
Start by checking if you can run Snow Leopard:
Requirements for OS X 10.6 'Snow Leopard'
http://support.apple.com/kb/SP575
The OS 10.6 Snow Leopard install DVD is available for $19.99 from the Apple Store:
http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
and in the UK:
http://store.apple.com/uk/product/MC573/mac-os-x-106-snow-leopard
but nobody knows for how long it will be available.
When you have installed it, run Software Update to download and install the latest updates for Snow Leopard to bring it up to 10.6.8, or download the combo update from here:
http://support.apple.com/kb/DL1399
Check via Software Update whether further updates are required.
You should now see the App Store icon, and you now need to set up your account:
http://support.apple.com/kb/HT4479
To use iCloud you have to upgrade at least to Lion, but some functions are only available in Mountain Lion:
http://support.apple.com/kb/HT4759
You can also purchase the code to use to download Lion (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard), or you can purchase Mountain Lion from the App Store - if you can run that:

    Look at what is happenning with your Mac when you run Activity Monitor.
    Macintosh-HD -> Applications -> Utilities -> Activity Monitor
    Click on System Memory to get statistics on memory usage.  You should have some free memory.
    When you have lots of page outs more memory will be helpful.  My entry for entry for Page ins/outs is:
    Page ins/outs: 29163/0
    Notice I have 0 pageouts which says that I am not using my harddrive for extra memory space.  Thus, I have enough memory.
    Activity Monitor has a neat feature where it can display a dynamic dock icon.  In Activity Monitor View > Dock icon > Show cpu history.

  • HT4906 how do i know what iphoto i have installed on my computer?

    i am trying to get icloud to work but it wont work with uploading my photos for some reason and it says i have to have OS 10.7.3 or higher which i do and i hve to have iPhoto 9 or something???? how do i know whats installed on my computer already?

    The following is for this Apple document: iCloud: Photo Stream FAQ
    What do I need to use Photo Stream?
    To use Photo Stream, including Shared Photo Streams, you need an iCloud account, compatible devices, and up-to-date software:
    iPhone, iPad, or iPod touch with iOS 6.0 or later
    Mac with OS X Mountain Lion v10.8.2 or later and iPhoto 9.4 or Aperture 3.4 or later
    PC with Windows 8, Windows 7, or Windows Vista (Service Pack 2) and the iCloud Control Panel 2.1 or later for Windows
    Apple TV (2nd generation) with Software Update 5.1 or later
    You can still use Photo Stream without Shared Photo Streams if your devices meet these requirements:
    iPhone, iPad, or iPod touch with iOS 5.1 or later
    Mac with OS X Lion v10.7.5 or later and iPhoto 9.2.2 or Aperture 3.2.3 or later
    PC with Windows 7 or Windows Vista (Service Pack 2) and the iCloud Control Panel v2.0 or later for Windows
    Apple TV (2nd generation) with Software Update 5.0 or later

    Your post establishes you have an iPad 2.   Is that not the case?
    An iPad 2 would be a Second Generation iPad.   an iPad 3 a Third Geneation iPad. and so on.

  • N97 - How do I know what Maps I have installed - a...

    As above!
    I recently went to Thailand, and thought I had downloaded the map for Thailand before I went. But when I got there and started up MAPS it started to DOWNLOAD via packetdata (no thanks it would cost 10 Euro/Mb). Apparently the Thai map was not installed, and there were no way of telling (as far as I can see).
    Also, How do I know when a new version of a particular map is out?
    In my Car System they update 4 times a year and I know when. But Nokia leaves me in the Dark.

    The only way to check if the map is correctly installed (other than  believing what Map Loader tells you) is to zoom in over the country concerned and check for the detail being present. Even though I've never had a problem, I always check this way after downloading just for the sake of paranoia.
    Nokia Maps are typically updated four times a year, but you won't get a notification - any time you conenct to Map Loader it checks your existing data, and if new stuff is abailable it deletes the old before you get chance to object and you then download the new maps.

  • How do i know what version i have?

  • ITunes will not let me authorize to play music. Claims I already authorized 5 computers. I have not (to my knowledge). Bug? My computer crached last year and a new HD was installed. Computer is Mac from 06 with Mac OS X10.5.8

    Have a Mac Power Book  bought 2005 when living in the US. Installed iTunes and set up an account. Have since dowloaded music, videos etc worth $1000s to my computer.... Last year 2012 my HD crashed and I had a new installed with operating system OS X 10.5.8. Can't upgrade to later systems. Before the crash I had long  since moved out of the US and forgotten my old user ID and password for iTunes as I hardly ever purchased any music or used the program. Luckily I had my library saved on external HD and on my iPod. I just bought an iPod Nano this Xmas and when I was going to download music to it I realized I had problems. iTunes claims being the latest version (10.6.5) but the Ipod Nano want 10.7 to be able to work with iTunes. I then started to try to access my music and  iTunes that I had not been using since the crash. It was an upgraded version and had new unfamiliar functions. I tried, to the best of my ability, to set up the account but to my frustration I can no longer access the $1000s worth of purchased music and music videos. ITunes just give me " I have already authorized this computer Including this one, you have authorized one computer out of your available 5". I only have this computer with iTunes! Is it a bug and how can I access my music?? I undestand I most likely will have to purchase a brand new computer to be able to use my iPod Nano I allways loved Mac and it's programs for its simplicity as I am no computer vizard but I am now desperate and at my wits end HELP!!

    In iTunes, do Store->View my AppleID
    Click "Deuthorize ALL"
    Then, on any computers you still have, do Store->Authorize this computer.  If there are less than 5, you will have no problem.
    You can only do "deauthorize all" once a year, so in the future, if you ever throw a computer away, remember do to "Store->Deauthorize this computer" first.

  • I am paying for CC but when I try to access LR  it says I need to use serial number which I don't have  have been using PS on same account for a while.  Tried adobe support but got cut off.  While online with them they said I didn't need serial number

    I paid for CC and have been using PS.  However, I can't get to LR.  It says I need a serial Number.  I contacted Adobe and they said that is not the case.  Then I got cut off.  Any fix?

    If you paid for CC-full-suite or CC-Photography-Plan then you should have a CC-licensed version of LR available, but only if you uninstall the serial-number-licensed LR you apparently have, now.   At least try that, uninstall LR 5, log out of the CC app using Gear / Preferences / Account / Sign-Out, reboot, log back into the CC app, and see if LR is one of the items listed.

  • HT204053 How do I  know what password I have for iCloud?

    Hi,
    Somehow I happen to have I cloud on my phone, maybe I got it with a new version of the OS. Pictures on my phone "disappear" to iCloud.
    But I never created any iCloud account, my phone wants to use the apple id but iCloud does not accept the password of my apple id!
    What to do?

  • I tried to download version 8.0 - how do I know what version I have?

    When I tried to download version 8.0, like others have found it does not seem to "take". Firefox, I suggest you get on this with some assistance while we are still with you.

    You can go to the About Firefox page to check your version. It looks like your user agent is messed up.
    Type about:config in the URL bar and hit Enter
    If you see the warning, you can confirm that you want to access that page.
    Filter = general.useragent.
    Right-click the preferences that are bold, one line at a time, and select Reset.
    Then restart Firefox

  • After last icloud backup, unrequested by me public holidays in the UK have been marked on the calendar and I can't find how to delete this. Also, I have been trying to delete a birthday from the same calendar for months and it keeps reappearing.

    iPad 2 with iOS 7.01 After the last backup to Icloud, unrequested by me,  my calendar has been filled with public holidays of the UK which there doesn't seem to be any way of deleting. Also, I have been trying to delete a birthday from the calendar for months, this time using all variations of 'delete' and it keeps popping up again!

    Are you also restoring from your backup? That sounds like what is happening or someone else has your Apple ID.
    A backup to iCloud would have no way to add UK holidays to your calendar. Open Calendar, tap on Calendars at the bottom middle of the page and untick the ones you don't want.

  • Why am I continually being asked my security question on my banking application when I use either Windows XP or Windows 7 and Firefox 3.6.13 but not on my Windows XP system with Firefox 3.6.3?

    I have three computers, two run Windows XP. One of the XP systems has Firefox 3.6.3 and the other has 3.6.13 installed. The banking application login acts normally with Firefox 3.6.3 but each banking login requires the security question answered with Firefox 3.6.13. This happens on both the Windows XP system using 3.6.13 and the Windows 7 system using 3.6.13. Testing Internet Explorer on all three computers does not show the same problem with the security question.
    I am unable to trace this starting with any particular Firefox update due to initially thinking the problem was with the banking website.
    The login webpage is https://you.usersonlnet.com/asp/USERS/Common/Login/NetLogin.asp

    I believe I've solved this issue by carrying out the following action:-
    First cancel all “send and receive” operations in OutLook. Next remove all emails from your "Outbox" (by either deleting them or moving them to the “Draft” folder). Next shutdown OutLook and then click on the “Start” button on the lower left-hand side of the Window’s taskbar, then click on “Run” now type in “regsvr32.exe inetcomm.dll” without the quotation marks, so it looks like this:
    regsvr32.exe inetcomm.dll
    Note the space between .exe and inetcomm.dll and hit “Enter” on the keyboard.
    The computer will execute the command. If all goes well in a few moments a dialog box will appear and state “dll registered successful
    I have not had it hand since ... cross fingers ;)
