Anyone know if Mountain Lion resolves the rapid battery drain associated with Lion?

When I installed Lion on my MacBook Pro, I, like many other forum users, noticed a dramatic drop in battery life. No matter what troubleshooting measures I took at the behest of Apple Geniuses, the battery life dropped from a high of about 8 hours to a paltry 3.
So, anyone heard if the newest version resolves this problem for MBP users?

I hope I am understanding your post.
All I'm saying (in response to Smoke Monster's argument of "it uses more RAM and therefore more battery")  is that it does't make a difference how much RAM an OS uses, as OS X doesn't distinguish between blocks with content and blocks without, they are all being powered/fired at the same time.
So I was told.  So if you had 8GB before and 8GB now, it's not the RAM that uses the additional power.
If you had 4GB and upgraded to 8 because of ML using more memory, THEN your battery may suffer a bit.
I'm not excluding a 1000 other reasons for shorter battery life, just the RAM.
More likely would be system processes using the GPU (or CPU for that matter) more than before on some machines.

    Open General preferences in System Preferences. You can set the desired scrollbar behavior there.

  • I get an error message when trying to sign into the support community with another Apple id. On the pick a username screen I get "an account utilizing this address already exists...." despite trying a few usernames. Anyone know how I can resolve this?

    I get an error message when trying to sign into the support community with another Apple id. On the <pick a username> screen I get "an account utilizing this address already exists.Only one account per email address is allowed on the Apple Support Communities" despite trying a few usernames. Anyone know how I can resolve this?

    This problem has been driving me demented. The instructions that Ivan gives have partially worked for me. By following his link
    "How to find out if you have multiple Apple IDs" I was able to identify that yes I did have two apple accounts using the same e mail address. One was very old that I used to use for the forum boards and one is my much more recent ID that I use for everything these days. So I changed the e mail address for the old account which is associated with these discussion boards and that's the account that I am now posting this from. However even though the two accounts now have different e mail addresses when I try to log onto the boards with my more recent main apple ID I still get all the same errors as described at the start of this thread by rodgers_j. And of course that's the one I want to use so that I only have one itunes account for everything.
    So if anyone has any more hints I'd be very grateful.

  • Does anyone know why or what is the reason when starting a new iMac with Lion a gray bar sometimes appears when loading software?

    Does anyone know why or what is the reason when starting a new iMac with Lion, sometimes a gray bar appears under the Apple that begins to shade to dark as it loads OS?  It does this on occasion.  One time the system loaded was VERY slow and terrible colors.  Pulled the plug, re-started the computer and it did not do this.  As I say, its only on occasion, not every time.  I noticed in the discussion page there were problems listed for 10.6 nothing for Lion.
    Please advise, if possible.

    You should see this 4 option menu.  Click on Disk Utility:
    In Disk Utility, Select FIRST AID and then VERIFY and then REPAIR the disk.
    Ciao.

  • I need to reinstall my Final Cut Express.  I have a version of 3.5 and then an upgrade to 4. Somehow I have managed to mislay the serial No for 3.5 so cannot install.  Does anyone know how I can resolve this.

    I need to reinstall my Final Cut Express.  I have a version of 3.5 and then an upgrade to 4. Somehow I have managed to mislay the serial No for 3.5 so cannot install.  Does anyone know how I can resolve this.

    If version 4 is an upgrade only, you will have to have the serial number of the 3.5 full version.
    If you can't find it try contacting Apple with your proff of purchase, they may be able to help.

  • My MacBook Pro turns on but not all the way, it gives me an icon of a grey folder with a question mark in the middle, and won't go further that that. Anyone knows why, or what's the problem?

    If these do not resolve the issue or if you are not comfortable with proceeding through these steps then take your Mac to an Apple store or an Apple Authorized Service Provider.  An Apple store will perform these initial steps, diagnose the problem, and give an estimate for repairs (if needed).  If the Mac is less than one year old or is covered by AppleCare any repairs would be free.

    Can't SEND email from Telus account in Alberta, Canada, unless I go to web mail. Does anyone know how to set up the Outgoing server? Incoming is fine. Outgoing used to work. We changed it when we went to another location, and can't get it back. Telus support can't fix it. Neither smtp.telus.net NOR mail.telus.net works for Outgoing server to send mail. Please help! Thanks.

    Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
    Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts   Tap on the Account, then on the red button that says Remove Account.

  • HT5621 When I got my new iPhone and was trying to switch everything over I accidentally set up a new icloud account with one email and had one on my old iphone with another account. Does anyone know how I can merge the two accounts?

    When I got my new iPhone and was trying to switch everything over I accidentally set up a new icloud account with one email and had one on my old iphone with another account. Does anyone know how I can merge the two accounts?

    You cannot merge Apple IDs but you can go to Settings > iCloud and 'Delete Account'.  When prompted to turn off documents and data, choose the only option which is Delete from my iPhone, but on the other prompt for Contacts, Calendars, etc you can choose 'Keep on my iPhone'  Then once the Account is Deleted form the iPhone, log back in with the correct Apple ID and choose Merge when prompted.  This will merge your data from this iPhone with that iCloud account effectively putting your devices on the same account.

  • Does anyone know how to simply edit the text in the spine of hard cover, 40 page book in the book mo

    Does anyone know how to simply edit the text in the spine of hard cover, 40 page book in the book module? I can click into any other text window and edit and change attributes but I am locked out of editing text when it comes to the spine of the book. I spoke to Blurb support and they referred me to Adobe. I spent 45 minutes with support here - no one knew. I am still waiting for a call back with an answer... not holding my breath as it's been a few hours now. HELP!!!

    Thanks for your reply John. I have experienced all the fiddly aspects you mentioned - these are attributes and although changing them requires the skill of a surgeon's hand - it's the actual editing of the text I can't seem to access anymore. The box just won't allow me to do anything except change attributes. Does that make sense? And it's only on the spine where I am having this issue. Puzzled! I have even rebooted the program and just now the computer - to no avail. 

  • Does anyone know how to turn of the pop-up iCloud log-in window on iPhone. I have no desire to use iCloud. I have turned off iCloud in settings but the pesky little critter is not deterred.

    Does anyone know how to turn off the pop-up iCloud log-in window on iPhone 5c. I have no desire to use iCloud. I have turned off iCloud in settings but that does not seem to deter the pesky little pop-up from continually asking me to log-in
    Thanks

    Pop up usually meant that icloud activation lock is still on on Apple servers. In order to deactivate you need to turn icloud back on by signing in and then sign out properly. For your sake I hope that you know the password.

  • Does anyone know how i can get the older versions of the ipod software

    Does anyone know how i can get the older versions of the ipod software on my nano because my nano had a feature that when i held down the menu button for a couple of seconds, the backlight turned on.......well ever since i downloaded the most recent software, everytime i hold down the menu button, it goes directly to the menu(which im not very enthusiastic about). Can anyone please help me if you can? I appreciate your help=)

    i agree with you 100%, i really want that feature back! it was so useful being able to turn the backlight on and off whenever i wanted. unfortunately im in the same boat as you are as i dont know how to get the old software
