Lion does not allow disk sleep?
Background:
MacBook Pro 17" Early 2011 MC725LL/A
Mac OS X Lion 10.7.1
Lion OS is installed to SSD located in OptiBay.
Synopsis:
Lion OS prevents my HDD drive located in primary HDD slot from sleeping: HDD spins up every few minutes. I do not manually perform any operations that should have called the secondary HDD to spin.
I did the following to prevent my HDD from spinning:
- sudo mdutil -a -i off - to disable Spotlight searching and indexing of my HDD
- manually added my HDD to Privacy Spotlight list
- sudo pmset -a disksleep 1 - to limit spinning time to 1 minute
- Disabled/Enabled Sudden Motion Sensor
However, every few minutes HDD spins up and I have no clue what causes that. No iStat Menus, MenuMeters or similar software installed.
I have this behavior after I upgraded my Snow Leopard to Lion via Mac App Store, made a brand new installation of OS 10.7.0 and 10.7.1 from a flash pen drive.
Similar configuration under Snow Leopard works as expected: the HDD idles until I manually call files located on it.
Have you tried unchecking everything under sharing? Some guy found that was his problem and he could then recheck it afterward without problem.

My MacBook running Mountain Lion does not allow me to view any videos on the Internet. The place where the video is supposed to be just shows black rectangle. Is there anything I can do to make videos on line work? I discovered that Java quits immediately. Could that be the cause? If so, how do I fix it?

OS X Mountain Lion does not allow me to change the disk contents
Hi everyone,
Last night, I noticed that I am not able to move files on my desktop to the Trash. Moving a file to the Trash, required me to enter my password. Even entering the correct password, did not remove the file. This just happened to files on the desktop.
I don't know why, but I have checked all the user and privacy settings in the system preferences. Nothing has changed since the last time the system worked as expected.
Can anyone help?
Thank you,1. Triple-click the line below to select it:
~/.Trash
2. Right-click or control-click the highlighted line and select
Services ▹ Show Info
from the contextual menu.* An Info dialog should open.
3. The dialog should show "You can read and write" in the Sharing & Permissions section. If that's not what it shows, click the padlock icon in the lower right corner of the window and enter your password when prompted. Use the plus- and minus-sign buttons to give yourself Read & Write access and "everyone" No Access. Delete any other entries in the access list.
4. In the General section, uncheck the box marked Locked if it's checked.
5. From the action menu (gear icon) at the bottom of the dialog, select Apply to enclosed items and confirm.
6. Close the Info window and test.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). Open a TextEdit window and paste into it (command-V). Select the line you just pasted and continue as above. -
MacBook Pro does not go to sleep when power cord is connected
Hi Experts,
I have recently discovered that my MacBook Pro (2009) with OSX Lion does not go to sleep when the power cord is connected. It does not matter if I close the lid or select sleep from the Apple menu. All that happens is that the screen is powered off, the SIL is solid and I can hear the HDD/fan. I have not changed any of my power settings recently and it has not been a problem previously. If I disconnect the power cord the MB goes to sleep as supposed to (the SIL led starts flashing).
Doing some research I have found other users with somewhat the same issues when VMWare Fusion is installed. I have done some further testing and it seems that if I disable the virtual machine's Network Adapter and quit VMWare Fusion the MB goes into sleeping mode when the lid is closed even with the power cord connected. Enabling the Network Adapter again prevents the MB to go into sleeping mode when the power cord is connected. This even applies when the VMWare application is shutted down.
My guess is that the Network Adapter somehow prevents the MB to go into sleeping mode. The workaround is of course toggling the Network Adapter on and off but the virtual machine has to be running in order to do so. Not being that familiar with network settings on a Mac is there any other way to get around the problem?
Thanks in advance :-)To anyone,
I have turned internet sharing off but the Ethernet box remains checked. If I uncheck the Ethernet box, the Internet Sharing bubble turns red, however when I close System Preferences and re-open, the box is automatically checked although Internet Sharing is off. Because of this my Macbook Pro will not sleep properly.
All other sharing items are turned off. Only Internet Sharing continues to automatically show Ethernet as active from a Wi-Fi connection.
Any advice? -
Disk Utility does not allow HDD to be erased
I am attempting to erase my Hard Drive so I can start from scratch and the disk utility tool does not allow me to erase. The hard drive is grayed out. I want to reimage my computer, but I cannot use the CD that came with it because it came with Snow Leopard, and I am running on Lion.
Please help, I need this. Thanksheatheranne wrote:

Any word?
You can not erase a drive you are booting the computer from. That would erase the operating system you are currently using.
You have to boot the computer from a inistall DVD or if you are using Lion from the Recovery HD partition. Or if you made or bought a Lion install USB thumb drive boot from that.
Then erase the drive and reinstall. -
How to Uninstall Yosemite? System does not allow Erase the HD, nor does it allow re-install of original O/S Disc (10.6.7). I want Mavericks or even Lion Back. Thanks.
Start with reinstalling Snow Leopard:
Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
with your computer. Insert the disc into the optical drive and restart the computer.
After the chime press and hold down the "C" key. Release the key when you see
a small spinning gear appear below the dark gray Apple logo.
2. 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.
After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
size.) Click on the Partition tab in the DU main window. Set the number of
partitions to one (1) from the Partitions drop down menu, click on Options button
and select GUID, click on OK, then set the format type to MacOS Extended
(Journaled, if supported), then click on the Apply button.
3. When the formatting has completed quit DU and return to the installer. Proceed
with the OS X installation and follow the directions included with the installer.
4. When the installation has completed your computer will Restart into the Setup
Assistant. After you finish Setup Assistant will complete the installation after which
you will be running a fresh install of OS X. You can now begin the update process
by opening Software Update and installing all recommended updates to bring your
installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1 Access the App Store to download Mountain Lion or Yosemite. Mavericks is no longer available since the release of Yosemite. If you purchased Mountain Lion from the App Store, then you can redownload it via your Purchases page in App Store. If not, then you will need to purchase it from Apple;
Purchase a redemption code at the Online Apple Store: OS X Mountain Lion. Mountain Lion is $19.99 plus tax. Use the code to redeem a download of Mountain Lion from the App Store. 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. -

it shows in the disk utilities but does not allow me to find a problem or fix the problem? Please help. also my external hard drive is a seagate free agent go, 500GB. it is visible on my tv but has no files in it… i'm scared i've lost everything?
Honestly i cannot remember sorry, i got it like 5 maybe 6 yrs ago and just started downloading things to it as the memory on the computer started filling up and when i wanted to see photos/videos on my TV.
My wife did tell me after i had written this post that she did try and record TV to it as it was plugged in. I think by doing so somehow has deleted everything. It reads on my TV yet has no files in it but won't show up on my computer. hope this helps.
Starting to think it is going to cost more to retrieve files on it than it will be to buy a newer and larger one. -
Hi, when I tried to create a new 1GB partition (on my Mac mini 2011, using Mac OS X 10.7.3) and then to delete it I could not restore (increase) Macintosh HD size using Disk utility (diskutil list shows the same value for Macitosh HD (498,17GB) partition before and after I deleted a new created 1GB partition).
Please help, how I can restore the original size of Macintosh HD when Disk utility does not allow to restore Macintosh HD after I deleted a small size (1GB) partition?
Thank you.The bottom right corner dragging does not help in my case, because it shows that Macintosh HD partition size is maximal, but its real size did not change after I removed 1GB partition.
Maybe any other idea can help me, for example some built-in tool like diskutil which allows to view and manage unused partitions in terminal?
Thank you. -
Safari 5.1.2 still does not allow me to view PDF documents in web pages. I am running OSX Lion 10.7.2. Any suggestions?
Read here > Known Issues | Adobe products on Mac OS 10.7 Lion
And go to ~/Library/Internet Plug-Ins
Move the PDF Browser plugin to the Trash.
Quit Safari, empty the Trash.
Relaunch Safari. You should be able to view PDF files now.

Boot Camp Assistant does not allow partiton when my disk is the right format
Boot Camp Assistant does not allow partiton when my disk is the right format - (Mac OS Extended (Journaled) volume).
When I go to the Boot Camp Assistant to partition the Macintosh HD disk, an error comes up saying,
"The disk cannot be partitioned because some files cannot be moved
Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."
Please help me out! I would really appreciate it!I was not allowed the Repair Disk option. I tryed Verify Disk, and an error came up saying,
"The volume Macintosh HD was found corrupt and needs to be repaired.
Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk."
What should I do? -
Help ,Disk utility does not allow me to partition my internal HD
hello , i want to partition my internal hard drive but for some reason disk utility does not allow me to , when i click on the partition window everything is greyed out, i read on other thread that file vault might be the problem but is already off , i can t figure out what the issue is any ideas ??? here is a screenshot.
Not if you want to be able to restore the Boot Camp partition using Boot Camp Assistant. There are alternative boot loaders you can use to add Windows and Linux to an OS X drive. You would first need to restore your drive by deleting the Boot Camp partition you now have. Then take a look at The rEFInd Boot Manager: Getting rEFInd - Roderick W. Smith.

With Mountain Lion MacPro does not wake from sleep
I have installed Mountain Lion (10.8.1) on a Mac Pro (Model appeared early 2008).
However when the system is sleeping, Mac does not awake from sleep by pressing any key of the keyboard.
The keyboard is inactive.That's interesting, I don't use the Apple->Sleep, but I tired it several times with 10.8.1 on my system and it woke up in a timely fashion.
There is something strange going on with it being intermittent for me, a combo of always & intermittent for you.
I suspect there is some combination of circumstances that's not obvious that's causing it.
I've looked through the logs and don't see any clues.
I submitted a bug report some time back.
You might consider submitting one as your situation is a little different and you have a circumstance that always causes the problem.
You need to be register here it's free, and then you can submit bug reports here -
Whne I download iTune, it shows that it will be downloaded to Drive K which does not exist in my computer. It does not allow me to change to other Drives has enough capacity. Then I click change bottom, attempting to change drive, it terminates the download.
Do you have any solutions??Try "Invalid drive X:\" install errors. You should still be able to chose the drive for the download when downloading the installer with a web browser. The iTunes application is installed on the active system drive, usually drive C:.

Windows 8.1 does not go to sleep reliably anymore
I recently did a clean install of Windows 8.1 Pro x64 (final version). Before doing the clean install, all hardware being identical, my Windows 8 was ran smoothly and went to sleep fine automatically after the set time.
Now, after the clean install, although I believe I have installed and set up everything as before, the computer does not reach standby automatically anymore most of the time. To be precise, when I reboot or log off and on the PC, the sleep functionality
is re-established for a while, but after 1 or 2 hours of work it invariably gets lost.
However, as soon as I disable the Ethernet adapter, the PC sleeps as expected.
I do not seem to be able to figure out why this is, or how my configuration is different than before.
Here are a few specs about my hardware: ASRock Z77E-ITX mainboard (http://www.asrock.com/mb/Intel/Z77E-ITX/, has the Windows 8.1 compatibility sticker), Intel Core i7-3770, 4x 3.40GHz including Intel HD 4000 integrated graphics (no external graphics installed),
Intel 530 Series SSD, Intel 520 Series SSD, WD HDD. I have use a wired Ethernet connection, my Ethernet chip is from Broadcom. Wifi chip is disabled.
Since this has been a pervasive issue with all Windows versions, the internet is full of suggestions how to resolve this matter. Why I am not convinced that the old advice still has any bearing as I tend to think Windows 8.1 introduced new issues (bugs?),
for the sake of covering all bases, I tried almost every tip I could find on the net and will list my fruitless attempts in the following. It might also be useful as reference for other people trying to tackle such issues.
1) Installed latest Windows 8.1 drivers from Asrock's homepage. I also tried chip manufacturer's like Intel's own drivers, did not make any difference (so far).
2) Left the homegroup and disabled homegroup functionality as for example in these threads it has been argued that this is a new issue with Windows 8.1: http://www.eightforums.com/general-support/28226-windows-8-1-refuses-sleep-2.html
http://www.eightforums.com/general-support/33221-windows-8-1-does-not-go-sleep-standby-automatically.html
3) In the Ethernet adapter's settings, I unchecked ipv6. I also made sure the device cannot be awaken through the network.
4) I even went so far to disable network discovery as
file and printer sharing (both in private and public profiles) and disable
public folders.
5) Even though sharing is disabled, I also made sure that within the energy options the computer is
allowed to sleep when sharing media.
6) powercfg /requests returns "none".
7) ran powercfg /energy duration 300 from an elevated command prompt while the ethernet adapter was enabled. It found 9 errors, mostly related to USB hubs, but the same errors were also recorded when I repeated the exercise having the ethernet
adapter disabled. So these errors are probably not relevant for the problem at hand.
8) powercfg /devicequery wake_armed : just the mouse and keyboard appear
9) I tried netstat which shows many connections but do not know how to interpret them or what to look for. Same for
Wireshark. If anybody can guide me on how to use these tools, I am happy to learn about it.
10) powercfg -requestsoverride DRIVER \FileSystem\srvnet SYSTEM
did not help, reverted it.
11) Uninstalled software some would find suspicious: Cisco Anyconnect VPN Client, Shadowprotect Desktop backup software, VMware player. Did not help.
12) I also have a MySQL server installed, which I did NOT uninstall because it would be too much point reinstalling and reconfiguring it. However, I doubt this is the culprit as with Windows 8 it did not prevent any sleep. Even when I stop the server the
PC does not go to sleep.
This is more or less it. I am out of ideas and welcome any feedback.
Again, when the Ethernet adapter is disabled, the PC sleeps as programmed, but I cannot figure out what communication is responsible for keeping it awake.
Thanks,
SteveHi Steve,
I don't know if you'll feel better but - You are not alone facing the same problems, I am sure that all the power handling in 8.1 is a mess. If I force the comp. to go to sleep mode, after a while it is
not staying in the sleep mode but shutting down autonomously. I suppose there is more hidden bugs.
Tazlam
Isn't your computer just switching from sleep mode to hibernation mode after the amount of time set in your power management settings? This sounds like it, as in hibernation the computer is effectively shut off. This is also intended behaviour.
As you guys, I hope MS releases a fix soon.
