On the left hand side of the page is an emac link or just scroll down to about three quarters down on the page and look for a link called "emac.pdf" NOT "eMacatigraphics.pdf". Download the PDF and search in the document for PMU or PRAM it has instructions for reseting the PMU (PRAM). Basically there is a little button next to the battery under the access door (where the RAM and stuff is) to reset everything. Just follow the directions precisely and you should be fine.
Hope that helps.

MacBook does not startup unless I reset the PRAM.

Several times now I have turned on my MacBook and been greeted by a dead, blue screen. The computer does not load Mac OS X from this state. If I reset the PRAM (by forcing a shutdown and then holding CMDOPT+PR when the computer turns on) Mac OS X loads. Why does this happen?
I have made some modifications to the computer that may have influenced its performance.
1. Upgraded to 2GB RAM.
2. Uninstalled extra languages using the program Monolingual.
3. Disabled Dashboard.
4. Disabled Spotlight.
5. Disabled Journaling on my harddrive.
6. Repaired disk permissions.
7. Cleared logs and caches and ran Cron Scripts using the program Ultimate Task.

I think I have some other information, or hypotheses which i'd love other users to share information on.
I notice, that when i have this problem, that in System Preferences/Startup Disk that the MAC OS X system is not selected/highlighted.
Also, I was thinking, perhaps this is due to having bootcamp/windows installed ?
So 2 questions:
Do users experiencing this problem have Bootcamp installed with a windows system on their mac
and
After getting the dark grey screen and starting up (by resetting PRAM), does the System Preferences/Startup Disk that the MAC OS X system is not selected/highlighted ?
If this is the case, I guess we have a bit more information to go by...
If users that are experiencing this issue do not have bootcamp installed, then at least we can rule out bootcamp (since it is a beta).
If users are reporting the same nonselection of the system volume in system preferences, then at least we're talking about the same problem.

My Mac is 15 months old and all of a sudden it has started resetting the time and date then I get a message saying not all apps will work because of the pre Jan date any help as to why ? Causing problems with wireless router.

My Mac book pro is 15 months old and now suddenly it has started resetting the date and time, causing problems with applications and my wireless access. Any suggestions as to why this is happening and how to fix it?

Seems the time isn't being saved to your computer correctly, it may be a corrupt file that isn't saving the time anymore.
You can move the
com.apple.systempreferences.plist
file out of your Users/Library/Preferences folder to the desktop and reboot.
then go to your System Preferences > Date and Time and set a time server close to your location (or in your time zone)
(trash the file on the desktop if no ill issues occur later on)
or you can follow/bookmark these support docs to reset your PRAM and SMC (and for future reference)

I don't remember exactly where OS X is keeping it time settings now, but I think one of those choices should help resolve your issue and won't hurt anything giving them a shot. Perhaps someone else could refresh my memory.

Re-implement a note that has been reset?

Hello,
Can you re-implement a note that has been reset? I am trying to but am getting error message "not all required corrections were implemented".
I deimplemented the note instead of trying to upload the new version of the note. Now I am stuck without any code correction, and cannot implement the note.
Thanks for any help!

Hi Fabienne
Are you trying with the SNOTE transaction. if yes then try to apply the note manually
Best Regards

I've reset my PPAM before to get around Firmware lock, but I've upgraded to mountain lion and now need to do the same thing, but I can't reset the PRAM. I've heard of the chip that is on the post 2011 macs, but I must not have one? What to do?

I've heard of the chip that is on the post 2011 macs, but I must not have one? What to do? Also, I can not get start up chimes unless I have the factory startup disk in. Can the PRAM be reset with the factory startup disk in or must the mac boot from the hard drive? Need help.

My Macbook will not boot the operating system. It just goes to a blue screen after the apple logo and the spinning wheel goes off. I took the battery out and held the on/off button for five seconds and reset the PRAM. I have the old mac os disk.

My macbook will not boot. It goes to a blue screen after the logo and wheel goes off. I have taken the battery out and held the on/off button for five seconds and reset the PRAM. I have the the original os disk but have not put it in for fear of losing un backed op data.
Thanks

You won't lose any data unless you erase your hard drive.
Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the "c"key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it.When it comes up is your Hard Drive in the list on the left?
If it is then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've selected the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions.

That's why I try to connect iTunes but it need to enter passcode.

My ipad2 is disabled and my power button is not working, how to reset the passcode?

Hi, there is no fix for this unfortunately. However you can plug your iPad into iTunes and providing you have made a backup, you can restore from it
you say its disabled, what does the message on the screen say?

HT3964 USB port not working even after resetting the SMC and PRAM, what can I do now?

Hi All,
I've got the "USB port draining too much energy" error message a couple of weeks ago and since then I've tried many times to reset the PRAM and SMC but still, one of my USB port is not working.
Could anyone please tell what I can do next ??
Thanks a lot

If you live near an apple store make an appointment. They will perform a DFU restore using known good equipment.
If that doesn't work you probably have liquid damage.

Using Mac OSX 10.7.1: recently replaced our DSL modum & wireless router and suddently I can't get some web sites to load. Many do, but Twitter and others often do not. I've reset the browsing historty, forms, cookies and cache but it continues to happen.

Ok, first thing, why are you doing anything with WAMP or XAMPP when you're running a Mac? MAMP should be what you want unless you're not explaining part of what you are trying to do.
2nd thing, I haven't used MAMP in a while, but there are two possibilities for not seeing what you want to see once you have MAMP turned on. One possibility is that you already have "Web Sharing" turned on in your Sharing Preference Pane. If that is the case, port 80 will already be taken and you'll be seeing the default Apache install (files are stored at /Library/WebServer/Documents/). This would push MAMP to either not turn on it's web serving capabilities, or to push it to another port. The other possibility is that MAMP defaults to another port anyway. So instead of localhost, you might have to type in localhost:8080 or something similar. I believe the control panel that gets installed can take you to the currently MAMP-served page, and it can also help you change which port your serving on.
80 is the default port for web serving and the ONLY port that will let you get straight to the server without having to type in webaddress.com:port# instead of just webaddress.com.

My fairly new iMac has been giving me trouble with permissions. I tried to make the owner of the hard drive myself, instead of three groups I hadn't created. Now it won't start. I''ve tried safe boot and resetting the PRAM.. Nothing.

Reset the PRAM, safe boot, removed everything but the key
board. Gray spinning wheel.
It started with me trying to change permissions. I'm the
owner, yet it would give me problem when moving files from desktop to hard drive.
Now it says library extensions are missing. I never
touched the library.

Hi Ralph - likely you're right. The section below, taken from their site, looked like it may offer some hope:
Unlock what is rightfully yours
BatChmod can also give you back access to locked files, folders or disks. If something is locked, it can unlock it. If you no longer have permissions to files or folders, change the permissions back.
Sometimes, a whole hard disk can become inaccessible or locked and often, BatChmod can unlock those too!
If you moved a folder or files from another machine or another user on your machine, BatChmod can help set you up as their rightful owner.
As you say, a re-install is probably the best way to go, but I thought that given that nothing's working correctly now it might be worth a go. If it fails desiree274 can still proceed with a re-install.
