Can't wake my MacBook up from sleep after Mountain Lion update

I have a MacBook Pro spring 2011 model. I did purchase the Mountain Lion update in September and this is when my problem started. I do have the put hard drives to sleep when possible turned off. The only change I have made to the Mac is the ram, I upgraded to 8GB but haven't had any issues with it. Any suggestions on what to do? The hard restart or having to shut my Mac down everytime is a pain.

Do you have a Bonjour Sleep Proxy server on your network?
<About Wake on Demand and Bonjour Sleep Proxy>
If you do not have a Bonjour Sleep Proxy server on your local network, then you cannot allow your Mac to go to sleep at all. System Preferences -> Energy Saver -> Computer Sleep -> Never (slide all the way to the right).

Can I wake my Macbook Pro from Sleep with the Remote app on the iPhone?

I can't access my Macbook Pro remotely, specially after several hours of inactivity,, whenever I try to access content of my library through the remote app or the Apple TV I'm unable to wake my Macbook Pro up.
My Macbook Pro is 2012 model (the last with de CD Drive) and it's running the Maverick OS, my questions are:
* I'm unable to find the "Unable Power Nap while plugged" option on the energy saver tab... is that because the model of my laptop doesn't support that?
* In order to access content from my library remotely, should the "Computer Sleep" option on the energy saver be on "Never" instead of the "1 hour" that I'm currently using... or is there a way to still be able to wake up the laptop with those settings

I can't open a folder copied from windows after mountain lion install.

It worked fine with lion. Idon't understand.
Any help?? pleas??

All of your TBird mail files are located in ~/Library/Thunderbird/Profiles/XXX.default. The library folder is hidden in Mountain Lion by default. To make it visible open the terminal app in your utilities folder and type "chflags nohidden ~/Library" without the quotes.

MacPro shut down instaed Sleep after Mountain Lion Update

Sleep Mode works not longer after updateted to Mouintain Lion. It shut down and needs quite longer on a next Computer start - longer as if started normal after normal shut down before.

There have been many Sleep issues reported, search them out here. One thing you should try, is re-installing OS X.
Boot up holding command-r keys into your Recovery Volume.
The screen should give you these choices...
Restore from TM backup
Reinstall Mac OS X
Get help online
Disk Utility
First run Disk Utility Repair Disk, if you get errors run until no errors reported or reports "the disk cannot be fixed". Then, choose Reinstall OS X. This will be an install "in place" and shouldn't effect any of your own data or settings.

How can I wake my iMac up from sleep mode? Can I do it via iPad?
I've set the "Wake on Demand" in the system preference, but don't know the way to wake it up.

It wakes up automatically in response to requests for certain sharing services.

Macbook Pro will not shut down/restart/sleep/log out after Mountain Lion update

Dear all,
I upgraded from Lion to Mountain Lion yesterday and since then I have encountered a few issues:
- The only way I can shut down my computer is to hold down the power button or entering commands in terminals. The commands under the Apple menu do not work at all. No window opens when I click on it.
- The about this mac, force to quit, sleep, shut down and restart button, log out do not work.
- When I restart my computer, it takes 3-4 minutes to log into the account (it used to be less than 1 minute, I have an SSD).
I have tried all of these solutions to solve the problem:
- I created another user account and I do not encounter the same problems. It logs in quickly, can shut down etc.
- I have repaired the disk and the disk authorisations using disk utility
- I have cleaned up all caches and did maintenance using OnyX
- I have cleaned up all ACL using terminal
- I have never installed Kapersky (this was the cause of the problem for some people in the past)
I am starting to be a bit short on ideas. All I know is that there is a problem with my user account. I do not want to do a clean install as I have quite a lot of work stored on this user account and preferences that took me ages to set up. If I have to start fresh I will but I would rather avoid this extreme solution.
Has anyone else experienced such an issue? If yes, how did you solve it?
Thank you very much

Had the same problem and this worked for me:
Try deleting following two items:
~/Library/Preferences/com.apple.dock.plist
~/Library/Preferences/com.apple.dock.db
Make sure you take a screenshot of your current dock since deleting these files will reset your dock to default.
Now open terminal and do a sudo reboot w/ your password.
This solved the problem for me.

MacBook doesn't sleep since Mountain Lion

Since I installed Mountain Lion on my MacBook (alu, late '08), it doesn't sleep anymore. When I enter sleep mode, it looks like it's entering sleep mode, but it doesn't fall asleep properly. The screen turns off, but the fans keep blowing and it won't go "off".
Have tried SMC & PRAM rest, no luck. Also tried deleting some dock files (read that in another discussion), no luck either.
Any ideas?

After Mountain Lion update on a MBP from 2008 the Logic board fails

Hi there,
My Macbook Pro (A1226) lived happily until the day I updated to Mountain Lion.
After the successful update to the OS the screen started to flicker and the OS freezes.
This never happend before the update.
When I managed to recover from several Kernal Panics I found that the last driver loaded was the Display Driver which was loadad last before the crash.
I though it might have been a good idea to reinstall the old OS (Snow Leopard). But still the same issue.
The contact with the apple store was quick - but I really refuse to pay 461€ for a new logic board for

This approach was completly new to me, but anyway, usually if the specs are met, there is no reason installing new software on a 4 year old PC or notebook. Well Apple told me otherwise and I'm not happy about paying a fortune for standard Harware spare parts.
But actually noboby helped me so far.
It would be interessting to find out whether in the software update firmware updates were included. In this case Apple can pay for the repair.

Macbook running slow after mountain lion update

why? i have 2 gb of RAM, that should be more than enough, right?
firefox is running slow, everything is freezing. i have barely used any of my hard drive space with it being at 225.61 gb free out of 249.2 gb.
its really frustrating.....

Two gb is the bare minimum for running Mountain Lion.
The model 7,1 (Mid 2010, White Unibody) can use 8gb of 204 pin 1066mhz PC3-8500 RAM
These are good online stores for Mac compatible RAM
OWC http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3_Whi te - They offer Mac tested RAM at very good prices.
Crucial Memory http://www.crucial.com/ - good place to buy RAM from all over the world. They also have an excellent memory selector that allows you to choose memory based on your computer's model
Data Memory Systems http://www.datamemorysystems.com/apple-memory.asp - another good, cheap place to buying RAM if you live in the U.S.
Here are video instructions on replacing the RAM on the White Unibody.

If you don’t have the tools to open up the MacBook OWC has a set for $5.
