    Masher please use the uninstaller located in the Applications/Utilities/Adobe Installers folder.  Once Photoshop Lightroom is removed then please download Lightroom 5.5 from Adobe - Lightroom : For Macintosh : Adobe Photoshop Lightroom 5.5 and reinstall.

  • When I click a link to open a new window, the new window appears in the bottom right corner and I have to drag it up every time to enlarge.

    This problem only began today and only with Webkinz.com
    When my daughter went to login, the new window where she logs in was in the bottom right corner. I pulled it up to the display and it stayed there. When she tried to log in again later on in the day, the login window appeared in the bottom right corner of the screen again.

    Open Firefox -> Help Menu -> select "Restart with Add-ons Disabled"
    Firefox will close then it will open up with just basic Firefox. Now you can Enable the Add-ons and it should be ok. Check and tell if its working.

  • What's with the double window appearing out of nowhere in Address Book?

    There is one window visible all through the Time Machine process until the very end when suddenly a phantom Address book window appears.
    To recreate:
    Open Address Book
    Open Time Machine
    Scroll to the oldest address book window in TM
    Click Cancel
    TM returns to present and as TM quits the two windows appear.

    I duplicated this, and indeed, a second window shows up. However, it vanishes in less than a second on my machine. I believe it's the one shown while in Time Machine mode; apparently, when viewing the address book, Time Machine moves back to "real time" before closing the window, the opposite of what one usually sees. Are you saying that in your case, the second window stays open?

    You can try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.<br />

    Sometimes look-alike characters may be confused, also you may need to enter the previous registration numbers as well, if your Aperture version is an upgrade to Aperture 2 or 1.

    The device was synced to icloud some time ago. The Laptop PC I normally use with the device is not with me now and is being formatted for a different reason.

    Saw this solution on another post about an iPad in a school enviroment. Might work on your iPad so you won't lose everything.

    ‘iPad is disabled’ fix without resetting using iTunes
    Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
    I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
    Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
    1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
    2. Open iTunes with the iPad disconnected.
    3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
    4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
    5. Click ‘Setup as new iPad’ and then click restore.
    6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
    7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
    8. The first stage in the restore process unlocks the iPad, you are basically just cancelling out the restore process as soon as it reactivates the iPad.
    If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.
    ~~~~~~~~~~~~~
    Try it and good luck. You have nothing more to lose if it doesn't work for you.

  • Why the icloud window appears me at the reboot of the system, asking me my system password?

    1 - I installed the Mavericks system in my iMac.
    1 - Instalé el MAVERICKS en el iMac
    2 - I realized that I did not serve the FaceTime and iMessage
    2 - Me percaté de que no servían el Facetime y el iMessage
    3 - I reinstalled the MAVERICKS
    3 - Reinstalé MAVERICKS
    4 - Now a window appears asking me my iCloud password every time I turn off and restart or turn on my MAC
    4 - Ahora siempre que reinicio o apago y enciendo el MAC se me pide mi contraseña de iCLoud y los dos programas anteriores siguen sin funcionar!!!
    Please Help me...

    ISSUE FINALLY RESOLVED!!!!!!
    So, it turns out, I had to restore the iPhone...with a twist! Here are the steps:
    FIRST BACK UP YOUR DEVICE
    1. Go to the library (Hold option, click on "go" in the finder, then go to library)
    2. Go to your iTunes folder in this Library (not application support, the main iTunes folder)
    3. Go to the iX software folder (i.e., iPhone software, iPad software, etc.) and delete the file in this folder
    4. Hook up the phone and then click on restore iPhone.
    At this point, it will redownload the entire OS again. You must then restore the iPhone. As it is downloading the iOS, you can disconnect and use your phone for probably however long you want (I did the restore the same day as the download) and when you are ready you can hook up the phone and restore it.
    THE MOST IMPORTANT STEP FOLLOWS:
    And one many may dislike. Upon restoring the phone, you MUST select "Set-Up as new iPhone"
    You need to make sure you've backed up EVERYTHING elsewhere. 3rd party, non-apple/icloud apps will lose data through this method, and you'll lose all texts, your call history, and super old voicemails. The upside is that, if you've backed up, then you can just restart the process if you forgot something. But seeing as how the popup was interfering with my ability to use iCloud (I couldn't sync anything, such as calendar events, reminders, etc.,  unless I had gone into mail to sign in to iCloud), it was totally worth it....no more popups.
    My only wish is that this thread becomes popular. Many people have this issue and you should only use this method as a super last resort (after trying literally everything I had written previously).

  • Making the Network name appear on top bar?

    Does anyone know a way to make the Network name appear on the top bar. I have a split network in my house and would like to see which one I'm connected to at all times.

    No way to do that, you will need to go into the settings and look at the Wi-Fi connection. 

  • My Firefox window used to be about 3/4 of my screen width but after crashung and restarting is now full screen width. How do I get the Firefox window back to 3/4 screen width?

    I don't want my Firefox browser window to be the full screen width. How do I adjust the browser window width?
    Thank you.

    This can be a problem with the file [http://kb.mozillazine.org/localstore.rdf localstore.rdf] in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder].

  • HT5372 The icloud message appears on my ipad screen when i turn it on. I cannot get rid of it and the screen is frozen. It will not respond to anything. I cannot even turn the ipod off completely.

    I am having trouble with my ipad. When I turn it on the message that I have not backed up my iphone appears on the screen. I cannot get rid of it or acces anything. The screen is frozen. I cannot even turn it off.

    Hello Juno2162,
    Thank you for providing the details of the issue you are experiencing with your iPad.  I recommend following steps in the tutorial below to address an issue like this.  I think the step to reset your iPad may be particularly useful in this scenario:
    To reset iPad, press and hold the Sleep/Wake button and the Home button at the same time for at least 10 seconds, until the Apple logo appears.

  • The latest Firefox version won't expand to make text and images more visible on my 32" screen, although I have tried to adjust the advanced Windows appearance settings in the same way that has worked in previous versions of Firefox.

    Normally I have had to go to Control Panel; Appearances and Themes; Display; Settings; Advanced; Custom; and then I adjust the Customize Setting to 155% (149 dpi). I have hit on this setting through trial and error; larger and icons like the cursor get big and fuzzy. Smaller than 155% and text and images are tiny on the 32" wide screen. This time that procedure doesn't seem to work. The text and images remain too small regardless of setting, although the cursor icon gets big. I can manually zoom the pages, but that is clumsy and has to be redone. Does anyone know of an easy setting fix? I am not too smart about this stuff--mostly trial and error, but I do want to be able to enjoy my wide screen. Thanks!

  • My MacBook Air (OS 10.8.4) does not connect to projectors consistently using a VGA/Thunderbolt connetor. The Monitors/detect displays box that I am used to never appears. Intermittently the "arrangement" window appears in the Displays System Preferences

    My previous MacBook Air running an older operating system synced up just fine with these same projectors using the same minidisplay to vga adapter. My new computer has Airplay on it, and Airplay shows up on my menu bar on the new laptop where the displays icon used to appear. I cannot get the displays icon to display (even when I turn Airplay mirroring off). It used to show up on the menu bar and if I had projector issues I hit "detect displays" and it resolved. None of that appears to be available with the new operating system and Airplay on. I am not sure why.
