Mac pro won't wake up after installing Mountain Lion

After installing Mountain Lion in my Mac Pro it won't wake up after long periods of sleep. I have tried unplugging it for 15 seconds and plugging it back in and starting it back up. No help. I've reset the Pram with no change.

Two calls into tech support, but I think they may have helped me fix this.
CHECK:
\Library\LaunchAgents
\Library\LaunchDaemons
\Library\StartupItems
remove any third party software and set aside. (they told me I could keep some adobe, microsoft and HP items)
THEN CHECK:
System Preferences --> Users + Groups -->Login Items
remove any third party stuff from in there.
I'll know tomorrow morning if this REALLY works, but it dfefinitely allowed my computer to sleep and wakeup over a short period of time.

Mac Pro won´t "wake up" after I´ve been gone a while?

Hi all.
After having installed Mountain Lion on my Mac Pro (just over 1 year old), I´m having a strange problem.
If I´m gone from the computer for a short while, the computer goes into "sleep" mode (sorry, don´t know the correct term). When I come back, I just hit a key og move the mouse, and the computer wakes up.. Brilliant... works as it should do!
BUT, if I´m gone for a longer period of time (say 60 minutes plus), there´s absolutely nothing I can do to make it start again. I can hear that it´s on, and the light indicator over the power button is on, but nothing happens?! Only thing I can do is to hold down the power button until the computer shuts down, and then turn it on again.
This is really annoying, and has only happend with Mountain Lion.
Hope someone can help
Thanks!
Jesper

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged before the boot, while the system was unresponsive or was failing to shut down. Please include the BOOT_TIME message at the end of the log extract.
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message. When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into a message.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

My mac mini doesn't shut down after installing mountain lion?

Right after i installed mountain lion and checked all the new features, I closed all applications, clear ram, clear cache, clear print queue, made sure that nothing was running when i logged out(only one 1 user was logged on.) I shut down and it seemed normal until the mac mini restarted, saying there was a problem and the normal error report appeared on screen when everything rebooted(after I log back on.) I'm angry. Really what should I do, I just bought this on December 2011( i7 mac mini sandy bridge) of last year. I hope apple releases an update to fix this problem.
My first attempt was to go to disk utility and fixed it, it worked I was able to shut down. However after that it started to go back to the way it was and it still wont shut down. Yes Im able to do everything else like put the hardrive to sleep(yes it goes to sleep I made sure) and force closing applications. Right now Im going to attempt doing what I did before but I will appreciate if a representaive or an apple veteran would give me advice or some useful information on how to fix this problem.
This happened 8/18/2012 at 6:57(when I installed Mountain lion and checked.)

Mac Pro won't wake from prolonged sleep in Mountain Lion

My Mac Pro won't wake from sleep after it is in sleep mode for several hours at a time. It will wake if the sleep period is short. But if it sleeps overnight it will not wake the next morning. Nothing seems to work. It requires a hard restart. I am running OS X 10.8.2. I read in another site that this problem was fixed for Macbook Air and Macbook Pro by turning off hibernate mode in Terminal. But I doubt this would help with my Mac Pro.
Any thoughts or ideas?
Thanks.

My wifi is very slow after installing mountain lion on my Mac book pro

My wifi is very very slow after installing mountain lion on my MacBook pro.
What can I do?

Ha ha, I misread that as "My wife is very slow after installing mountain lion on my Mac book pro"
BTW on my MBPro (late 2009 with max RAM) Mountain Lion runs very well with no slowing down.

Mac pro won't read windows 7 install disc?

My 2007 mac pro won't read windows 7 install disc. My macbook reads the disc fine, so it is not a problem with the disc. It is 32-bit. The apple help line suggested firewire connecting the macbook to the macpro and starting the macbook in target disc mode, but other posts I have read have said that this will not solve the issue. Any suggestions?

Could be. I just rebooted and it read the disc. Unfortunately the windows install got interrupted and I had to reboot, and now it wont read the disc again. Is there any other way to install windows 7 to bootcamp, other than from the disc? Can I use FireWire and target disc my MacBook (the MacBook reads the disc just fine)?

If you're running OS X 10.8.5 or earlier, then from the menu bar, select
 ▹ System Preferences... ▹ Accessibility
If the checkbox at the bottom marked
Enable access for assistive devices
is checked, uncheck it and test.
If you're running OS X 10.9 or later, select
 ▹ System Preferences... ▹ Security & Privacy ▹ Privacy ▹ Accessibility
If any applications are listed on the right and have a checked box next to them, uncheck all the boxes and test. You may first have to click the padlock icon in the lower left corner of the window and authenticate as an administrator to unlock the settings.

Numbers does not open with the main user after installing mountain lion. It works flawlessly when I use the second account on my mac. What got corrupted in the admin-account, something in the user-library? How can I fix it? I´m kinda desperate...

Numbers does not open with the main user after installing mountain lion. It works flawlessly when I use the second account on my mac. What got corrupted in the admin-account, something in the user-library? How can I fix it? I´m kinda desperate... (the same happens with the other iWork-Apps!)
Looking forward to hearing from somebody with a littlemore expertise than me, Chris

you can remove preferences files by navigating to the Preferences folder for your user as follows:
0) Quit ALL iWork apps (Keynote, Pages and Numbers)
1) from the Finder select the menu item "Go > Go To Folder…". This will bring up a dialog:
2) enter the path "~/Library/Preferences" (no double quotes)
3) find the files:
com.apple.iWork.Keynote.plist
com.apple.iWork.Numbers.plist
com.apple.iWork.Pages.plist
and move these to the trash. I would NOT empty until later.
4) restart Numbers

My macbook pro is very slow after installing mountain lion

my macbook pro is very slow after installing mountain lion? Is anyone else having this issue?

If you don't use an SSD and bump your RAM up to 8 Gb's you may experience slow speeds, but I noticed slow speeds with your general configuration in SL.
one thing you should consider right now is, Spotlight is Reindexing your hard drive, that takes time and resources, (resources which you don't necessarily have to spare).
If you continue feeling like your performance is slow, you have a few options with this computer (I have the same one).
the express card slot can house a wintec SSD drive. That little door on the side of your machine is pure gold for a really quick solution for speeding up your machine. I have one in mine right now i'm using as a scratch disk for CS6 but I used to boot from it, and the speed boost was out of this world.
You could take out the internal HDD and put in a new SSD (I have a Vertex 4 from OCZ) it is completely over kill but my experience is pretty fast and I keep up with the later MBP models colleagues have.
There are some other options for you like taking out the optical drive (however I don't know if I'm supposed to talk about that here). Google Data Doubler.
You need to also set it to always use the 9600 chipset, this will increase performance a lot too. to do this go to system preferences>energy saver>Better Performance. This switches the video card to the better one and makes a world of difference.
Lastly, your RAM. after an EFI Firmware update, our computer support up to 8GBs of RAM. Do it!

Printer won't work after installing mountain lion?

printer won't work after installing mountain lion?

Assuming you've first checked Software Update to see if there are any updated drivers and it's still not working, you could try resetting the printing system.
System Preferences>Print & Scan, Control+Click or Right Click on a printer on the left and select 'reset printing system'. All printers will be deleted and need to be added again.

Why won't iTunes 10.6.3 work after installing Mountain Lion?

After installing Mountain Lion my mouse won't scroll

After installing Mountain Lion my mouse won't scroll up or down. It will, on occasion, scroll left.

Which mouse do you have? If it has a mechanical scroll ball on the top then it's simply dirty and needs cleaning. However if you are using Magic Mouse then please click iMac SMC and PRAM reset and do both resets 2x.

After installing Mountain Lion on my Mac I have no Internet. Safari doesn't work.

Try a PRAM reset and an SMC reset.

After installing Mountain Lion, my Time Machine won't back up ... says the sparsebundle is in use

After installing Mountain Lion, my Time Machine won't back up ... says the sparsebundle is in use

Standard problem in ML.. apple do not seem to want to recognise.
Reboot the TC .. if that fails restart the whole network in correct order.. modem.. router/TC... clients.. with 2min gap.
There are other suggestions like changing the password.. all they do is the same as reboot.
Read C12.. most quoted Q in pondini website history. This is asked 10 times a day.
http://pondini.org/TM/FAQ.html
Here is another way to get a useful utility in ML.. rather than toyland version.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. it is very simple.. drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. drill down.. applications utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall 6.1 so don't try.. and you cannot or should not run them both at the same time.. so just ignore the toyland version.. the plastic hammer.. and start using 5.6.. a real tool.
