Why is Mountain Lion requiring login twice from sleep?

I am running Mountain Lion (10.8.2) on an Early 2011 MacBook Pro. I have it set to require a password when left too long or asleep.
Frequently, after I enter my password and get logged in, it bumps me back to the login page after about 5 seconds. I'm able to work for those few seconds, but then everything goes back to the locked out screen. After I enter my password a second time, it always works. The work I did in those few seconds is still on the screen (new pages, text typed, etc).
This started happening after the upgrade to 10.8.
Thanks,
J

I've been running into this error as well, no external display, but I'm running an MBP 4,1 17in.
I've chalked this up to old preferences that weren't properly updated, the screen lock was automatically enabled by mountain lion, wheras prior to install, my 10.7 install did not have this enabled.
I haven't had a chance to check this with a fresh install yet.

Why do I have to login twice after sleep mode?

Until recently I have been able to login one time with a password to get to my desktop. Now I have to login twice and I have no idea why. I am running Yosemite, whatever the newest version is. I'm not too tech savvy, but have checked every setting I can think of to no avail. Any help would be appreciated.

Just to be clear, it's not normal to have to log in twice when FV is on. If you want to try to solve that problem, ask for instructions.

Macbook Retina with Mountain Lion issues after waking from sleep.

Macbook Retina with Mountain Lion has the spinning beach ball of death after waking from sleep a few times. Anyone else seeing this? A fresh boot is very quick, but waking from sleep lags at times. Then after a few times the spinning beachball of death appears and nothing is responsive making me reboot the machine.

I've been suffering from this too, and am currently trying this:

Seems to be tied to this 'Power Nap' feature. I tuned it for 12 hours instead of 24.

Mountain Lion Crashes on resume from sleep

Is anyone else having problems with Mountain Lion crashing frequently on resume from sleep? I have tried using both the default "sleep and hibernate" mode and switching to hibernate only. In both modes, OSX "gray" screens just after it appears to finish resuming from sleep mode. This is an Early 2011 MBP 15" with a clean Lion upgraded to Mountain Lion.
It is starting to look like another failed upgrade, "sigh". I haven't had any luck with OSX OS upgades and always seems like I end up rebuilding.

Same happening here. I also have a problem with Mail.app crashing when I close the window with cmd+w. My upgrade to Mountain Lion was applied Lion that had been migrated from my old MacBook.
The migrated setup was working fine for just over a week before I upgraded to Mountain Lion. Unfortunately I didn't check that Time Machine was backing up my machine and it turns out I don't have that as an option of rolling back to Lion.
Hoping that a fix is found to both problems. Fairly confident given that other people are reporting the same, even on a clean upgrade.

Jump Desktop on Mountain Lion - Won't wake from sleep

Installed Mountain Lion. Now it will not wake from sleep when connecting from my iPhone 4 or new iPad when connecting via Jump Desktop. Screen sharing is turned on and gmail account and password are all correct. No problem connecting as long as my MacBook Pro is awake. With Lion, there was no problem waking from sleep when connecting. Anyone have the same problem -- or a solution?

Had the same problem, as a work around tick the
'prevent computer from sleeping automatically when the display is off'
button in power settings
Although not in sleep, it means the screen is off but still can be controlled remotely
worked for me

Mountain Lion won't wake from sleep

I have an early 2011 MBP with 10.8 loaded. My laptop went to sleep and won't wake up. Are there shortcuts that may wake it or is the only thing to do is hold the power button? Is there a fix to this? It isn't power nap as I have a HDD.

Hi,
Please perform an SMC reset.
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option(ALT) keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Terribly sorry Joseph Kriz. I had absolutley no intention of annoying anyone. This was the first time I have been communicating in a discussion group, and as I wrote my comments I had no idea how my typing would reflect and where my question would be going. Hope my unintentional typing will be forgiven and causes no further agitation.The only additional comment I can make on your response is that "I do not use capital letters or CAPS LOCK while I try to enter my administrator password".

Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Why does Mountain Lion triggers front fan in Mac Pro?

Hi all, this is my first visit to this community and I hope there won't be much more .
I bought a new SSD drive for my Mac Pro (early 2008). I had to install it from my Macbook Pro because Leopard in the Mac Pro wouldn't allow me to.
Neither I could perform a bootable USB clean install since the Mac Pro didn't show the device in the drive selection splash screen.
Then I put the SSD back into the Mac Pro and eureka, everything worked just fine. After about 30 seconds with the desktop in front of me, the front fan of the Mac triggered like if it was a constant reboot. However, the system worked just fine with no trouble but the annoying noise of the fan.
It's an OS related problem because this doesn't happen in Leopard. Any idea what went wrong?

Faulty installation. Why could you not install the SSD in the Mac Pro running Leopard? Why are you running Leopard in the Mac Pro instead of upgrading it to Mountain Lion? Try doing it this way. Put the SSD into the Mac Pro.
Erase and Install
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your SSD (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. After formatting finishes quit DU and return to the installer. Install Leopard onto the SSD.
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later

Why is mountain lion so slow compared to snow leopard?

Just installed Mountain Lion from Snow Leopard (skipped Lion).   I like the features of Mountain Lion but it is incredibly slow in overal start-up and general system responsiveness compared to Snow Leopard.
Running iMac and Macbook Pro and both are the same in really slow performance.

OK, been a busy week but I've installed RAM.
Had iMac 2007 model (iMac7,1) with 2GB of RAM (two 1GB modules).   Upgraded recently to 6GB of RAM (one 2GB and one 4GB module), yes, I know this is above the original specs of 4GB, but this model does indeed support 6GB with Snow Leopard or newer.   This now works fine under Mountain Lion with no spinning multi-colored ball.   With a couple of applications like Safari and Mail open, it has (using Activity Monitor) just under 2GB free memory.   Page Outs are now a very small (close to zero) fraction of Page Ins.   So, it works well.     If you are not upgrading memory then stick to Snow Leopard as it is a much lower memory footprint.
Had Macbook Pro 2008 model (MacBookPro5,1) with 4GB of RAM (two 2GB modules).   This wasn't performing as bad as the iMac with Mountain Lion but was still slow.   Anyway, upgraded to 8GB of RAM (two 4GB modules).   This is also now working fine with no major issues observed.
If running VMWare fusion, then a lot of the memory will be used up.   The free memory is very slim on on an iMac when running VMware Fusion with MS Win XP (ugh!), which I only do for a couple of scientific antenna analysis programs that I like to use that just aren't available on the Mac, but it is workable. Occasional memory address messages appear from the guest OS but othrwise fine.
So, in summary, if you have older machines (with low RAM) or have a multitude of apps open then Mountain Lion requires careful consideration as it needs just over 4GB when a couple of memory hungry apps open. Do anything exciting andmemory usage will increase causing tons of Page Ins compared to Page Outs and you'll be running in slow virtual memory.   So, for machines that you won't upgrade in RAM stick to Snow Leopard.   For modern Macs with 8GB, 16GB or more, then all will work well.
I still wish they could make the memory footprint leaner though.

Why is Mountain Lion in "waiting" mode in my dock?

Why is Mountain Lion icon in "waiting" mode in my dock? Why is it not installing? I'm running a newer iMac with sufficient memory. I'm installing from Snow Leopard 10.6.8

Thanks for the advice. I selected cancel and restarted the process. It says it is downloading however, it disappeared and I chose to start the process again this a.m. I'm not sure whether or not it begins entirely again or carries on from before. It seems like a long, drawn out process, doesn't it? I've noticed the feed is starting so I'll let it run this morning and monitor the process.

Trying to upgrade osx 10.5.8 so that I can use apple tv/facetime etc. mountain lion requires 10.6.8 how can I upgrade my osx? help!

trying to upgrade osx 10.5.8 on my old macbook pro

Thank you~

Buy Snow Leopard from the online Apple Store - http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard - and update until you get to 10.6.8. Then, if you're computer is able to run Mountain Lion, you'll be able to purchase ML and install it via the App Store.
Good luck,

Why does mountain lion "bunch up" all my microsoft office documents that I have open when I hit f3? When I had snow leopard for example, if i had 4 or 5 different microsoft office documents open at the same time I could hit f3 and easily pick one of them

Why does mountain lion "bunch up" all my microsoft office documents that I have open when I hit f3? When I had snow leopard for example, if i had 4 or 5 different microsoft office documents open at the same time I could hit f3 and easily pick one of them.
Notice how in the photo, I can't identify which MS office document I would like to switch too. Perhaps since the Dashboard and Desktop windows are at the top of my screen now Apple doesn't let you have all the applications take up the full screen and be sized individually so that you can have a better idea on what to pick.
I like the idea of grouping to an extent... If you have a bunch of random things it was hard for me to decifer between what was safari, chrome, or word. But now that they grouped them like this, if you have multiple pages of one program running, you can't switch between those pages easily like before.

If I wanted to open any of my Applework documents I had to open them one at a time and resave them with pages. This could take weeks.I have 1000s of apple work documents.
You don't have to open and re-save every AppleWorks document you have right now. Just wait till you need one, then do it. The documents aren't going anywhere.
Am I dealing with Microsoft? This was a BIG surprise to me that Apple would release an OS without testing all programs.
Frankly, it is not Apple's responsibility to ensure compatibiltiy with every piece of software available for OS X. That is the responsibility of the software vendor. Lion has been available to developers for several months before it's release, so Microtek had plenty of time to update their software. Yet they did not. How is that Apple's fault? I think Apple was very generous to give you a refund for Lion.
I'm not trying to belittle your frustration but I do think your ire is misplaced.

I'm trying to re-install mountain lion 19.8.2 from a recovery disk and get an error when it's trying to verify my computer with Apple, any idea what's wrong?

I'm trying to reinstall mountain lion 10.8.2 from a recovery disk and I get the following error when I goes to verify my computer with apple,
An error occurred while preparing the installation. Try running this application again. Can anyone help?

Well, I'm trying to figure out how you're doing this from a recovery disk. The only way to reinstall Mountain Lion is through the Recovery HD in the computer. Hold Cmd/R as you are starting up the computer and keep holding it. Eventually you'll get a screen asking you to select the language. Hit continue to select english and you'll get a Mac OS X Utilities Menu with the second option down being reinstall OS X.

While intending to perform a clean install of Mountain Lion while continuing with old apps and files, is it a waste to restore a backup that was made while running Mountain Lion as an UPgrade from Lion?

While intending to perform a clean install of Mountain Lion while continuing with old apps and files, is it a waste to restore a backup that was made while running Mountain Lion as an UPgrade from Lion?
Originally I was running Mountain Lion as an UPgrade from Lion. I created a backup in Time Machine, performed a clean install of Mountain Lion, then I proceeded to use Time Machine to restore the back up.
When thinking about the essence of a back up restore, it occurrs to me that for all I know, I may have just wated my time IF Time Machine also restores all the old unneeded files that remain from Lion after an upgrade.
Since the backup was made while running Mountain Lion as an upgrade from Lion, did restoring this backup defeat the purpose of a clean install by reinstalling old Lion files?
If so, how can I re-do the last portion of the process so that I get all my home-folder files and apps back without the full bulk of old Lion files? Migration assistant I'm guessing?

Hello John!
Thank you for your response which solved my problem. For other users who may stumble upon this, I'll clear up the confusion and share how I solved the problem with your help; When looking for answers to my computer problems, finding unresolved questions where person B offers a solution and person A never comes back and says "That worked, thank you.", it demonstrates a "k-thnx-bye" user mentality that leaves others with the same problem lost. Without further ado:
It is not clear what you did because the meaning of "clean install" is vague. You can erase a volume and install an OS which leaves none of its previous content intact,
This is what I did: I erased the volume leaving no previous content intact, while then installing OS X Mountain Lion.
or you can upgrade an existing OS (or reinstall the same one) which does not alter your user - installed files.
An upgrade to Mountain Lion from Lion is what I started with initially before erasing anything. This was undesirable. Since this can cause Macs to run slower (especially whereas I'm using a mid-2011 Mac Mini), my goal was to go from operating within an upgrade to Mountain Lion, to operating within an installation of Montain Lion that was not preceded by any other oprating system.
Hence a "clean install of Mountain Lion while continuing with old apps and files" is confusing.
Well put and understood. What I should have said was:
1.Erase the volume
2.Install Mountain Lion clean
3.Confirm that Mountain Lion is functioning properly
4.Proceed to use either Time Machine or Migration Assistant to Import/Migrate/Copy over only two things; My old apps (That had been stored originally in the designated Applications folder) and all files and folders originally stored in the home folder under users.
If you restore from a Time Machine backup then all modifications that occurred subsequent to that backup become erased. It renders moot any OS X upgrade performed subsequent to that backup.
That makes sense and is just as I later suspected.
If so, how can I re-do the last portion of the process so that I get all my home-folder files and apps back without the full bulk of old Lion files? Migration assistant I'm guessing?
Yes.
This is what I did and everything works perfectly. Thank you so much once again!
