Can someone explain to me why resetting PRAM on a machine has any effect whatsoever for networking issues? ie; self assigned ip etc. I have noticed this is a common troubleshooting step that a lot of people are recommending for issues related to networking.
View 3 RepliesI am running Mac OS Lion (10.7.3) on a 8-core Mac Pro. As I turned on my mac this morning, I found out that I was unable to use my wireless mouse, and also that I couldn't open my bluetooth settings. Apparently, the entire module disappeared from the System Preferences, and when I went to one of the articles on here, I saw that I'm supposed to reset my PRAM and SMC in order to make my bluetooth work again. The problem is, that I don't know what PRAM or SMC are, nor do I know how to reset them.

I have already covered these steps:1. I have tried a safe boot. 2. I have tried to reset the NVRAM and the PRAM.3. I have tried to reinstall OSX from the Install Disk.4. I have tried to repair the HD and tried to repair permissions using the Disk Utility. he issue started out as the flashing Apple/Question Mark Folder/"No" sign. I attempted to follow the steps on the Mac Support Forums (ones listed above) and the issue developed into the picture shown.

I tried to reset my PRAM, however when I hold down "Option" "Command" "r" and "P" the computer won't restart. The hard drive seems to be stuck at this point and won't go any further. I went to the Apple store and the Genius lost patience and said we should send it out. (I'd rather not)
I have also reset the PMU
Everything else works fine.
I've looked at several other threads and post. Everyone with a sound problem seems to be able to get it resolved with a PRAM reset. However I find nothing on my the problem of not being able to reset..
I have a MBP 13inch from 2011
recently i zapped my Pram becuase i was having trouble with a external screen but when I turned it on again the screen when to the grey screen with the apple logo and spinning gear but after 2 hours of wating the screen is still the same. What can i do to get back onto my mac?

I have inadvertently left my 2011 MBP running with a processor intensive music app running. The battery ran out before i realised.. When i attached the power lead to charge it, the computer automatically restarted without even pressing the power button. The computer had not entered safe sleep mode, presumably because my music software was still running.
Since then the computer will not ever enter safe sleep when the power runs down. The battery just cuts out each time when it drops to less than 5%, it does not run out at 0% like it usually does. if it is the logic board battery because i have had this issue a couple of times before but it rectified itself after a few days. I have checked that safe sleep is enabled which it is, but the computer just cuts out before safe sleep kicks in.

I have tried two different brands of blank CDR in my drive and both times, they fail to mount and in Disk Utility, show up as Sony DVDs (neither of them is a Sony or a DVD), but not writable. I have no problem with media that already has content. I've tried resetting PRAM, but nothing else yet.

I tried the SMC & PRAM reset. Now, there is a delay in my keyboard and mouse. For example as I am writing this, as I type, I am observing a ~1/4 sec delay between me pressing a key and the GUI registering it. The same with the mouse. I can click-and-hold over say File and move it up and down over subsequent menu items and it the GUI doesn't highlight the menu item unless I slow down the movement.

Updated to OS X Mavericks last week. Ever since, it has been experiencing boot problems.
- If I restart my Macbook Pro (2011 13", lowest model), it will sit at the grey screen with apple logo and spinning grey wheel forever. I notice that my HDD is NOT running (no clicking / writing sounds)
- If I restart with a PRAM reset or holding down option to select Macintosh HD boot, the hard drive starts to run (I can hear it) and it boots successfully... it takes 5+ minutes to boot up. The grey screen with apple logo is presented on my screen for about 4 minutes, then the login screen shows up but I cannot move my mouse or select a login user for 30 seconds. After this, I can log in succesfully.
-Also, switching users takes 1+ minutes. Clicking "switch user" freezes my screen.

Recently my MacBook Air has failed to wake from sleep mode. The Apple illuminates on the back of the screen casing, but neither the screen nor hard drive actually wakes up. The only way I'm able to use the computer is by forcing a PRAM reset on restart (command-option-P-R). I've had to do this several times in the last two weeks.
The only things about my MacBook Air that have changed in that time period are:
- I installed OS Yosemite
- I installed and ran Sophos Anti-Virus
(The latter was installed to counteract a problem that I was having with my email address having been spoofed and sending spam. Sophos found two bits of malware in email data files and "cleaned" them up.)

Today I noticed that my mid 2010 MBP is not automatically sleeping. I ran Apple's extended hardware test, along with TechTools Pro 5 from AppleCare disk. Both passed. Reset the SMC and PRAM. I'm still not able to auto sleep. Is there a way to see what exactly is causing my computer to not automatically sleep? Console messages or something?

I recently purchased a 13" 2.26 stock macbook. It's perfect, screen is good (no scrolling issues or purple blues) with no dead pixels, no slanted keys, and no scratches.
I updated the firmware that addresses the SATA 1.5 issue. After the update, I reset PRAM. I held down the buttons till I heard the second or third startup bong.
Here is where it gets funny.
Now, when I reboot or start up my computer, the start up noise is loud. Even with headphones plugged in and also the volume turned to its lowest setting (even with volume turned off). Eventually, to control the startup noise, I had to install the startupsound program in my system prefs as mentioned on other threads and that has seemed to control the startup sound.
I was wondering, if by resetting the PRAM if I have harmed my computer in any way. Should I be worried about deeper issues with my computer since the startup sound was not previously being affected by reducing the volume to zero with headphones plugged in?
I understand the steps needed, but how many times should I reset the PRAM and how many times should I here the startup sound (in total) before releasing the buttons?
View 3 Replies View RelatedI attempted to reset the PRAM on my macpro running snow leopard this morning, by rebooting and holding cmd-option-p-r until the apple logo appeared, at which point I released and then machine then rebooted a second time. I went back to the computer about an hour later and it was stuck on the apple logo screen, with no sounds coming from the CPU. I did a hard reboot by holding down the power key and it started up fine. I've never reset the pram before and so I didn't know what I should expect as far as the process being successful, but after an hour stuck on the apple logo I figured it got stuck on something.

I have tried SMC and PRAM resets, and the issue has not been resolved. My magsafe is lit up with a bright green led. Battery status is "Not Charging." When I unplug the magsafe, the system immediately shuts down. Battery is brand new with only 2 cycles. While I can use the laptop with power connected, this is an issue that needs to be corrected asap, as I use this computer for performances consistently and if the power cord gets removed, I'm not in a good place.

My macbook pro won't boot past the grey screen, I've tried reseting PRam, running fsck from single user etc to no avail. All signs would point towards a hard disk failure, but the curious thing is that it sometimes mounts in disk utility when booting from the install CD, so theres a little life left in it yet! I have fairly recent backups of most of my files, but there are a couple I've been working on in the past few days that won't be backed up. So my question is this - is it possible to copy files from my mac HD onto a external drive through the terminal/disk utility while booting from the CD.
View 6 Replies View RelatedSo I contacted Apple this morning regarding the LCD Backlight Bleed on my iMac (24", early 2008, 2.8 ghz) They made me reset the PRAM, which I figured wouldn't work, and the issue is still there.
They say it'll have to go in for servicing, and I live nowhere near an Apple Store, so they gave me the location of the nearest London Drugs. Am I going to get the same quality of service as I would from an Apple Store? And what is the exact process that they use, do they just replace it with a new LCD?Also, he said that it will be covered under Applecare unless it is ruled as accidental damage, he said that much of the time, the issue is caused by pressure on the back of the case, and that if that was the case, it wouldn't be covered.I can't really see how this would cause it, and I haven't ever put any pressure or anything on the back, but i did buy the iMac used, what are the chances of this being ruled accidental damage?I have the bleed in all four corners of the screen, if that makes any difference.
Today the IT department at my university set up my Early 2008 MBP to work with the library WiFi. While doing this they completely messed up my airport settings so now I cannot connect to my home network. Is there anyway I can reset the network settings to default like they way they were before? I am running Snow Leopard.

With the introduction of Outlook 2011 for Mac, many Mac users are asking the burning question around how to sync Outlook 2011 for Mac with the native Mac Address Book. This is especially relevant as many users now sync their mobile phone contacts (Blackberry, Android, iPhone) with the native Address Book contacts manager. For example, RIM�s Desktop Manager for Mac syncs with iCal and the Address Book and relies on Sync Services to sync with Outlook 2011 contacts. If you will now be managing your contacts inside Outlook, you will need a way to sync these contacts back to the native Address Book.
This is also true if you are using Scrubly to clean up your Address Book contacts. You will need to turn on Sync Services inside Outlook to sync your newly cleaned up contacts from Address Book to Outlook Contacts. Follow the steps below.
Before we begin, you should note that Outlook 2011 will sync contacts from Address Book, and you can sync e-mail accounts with Mail. However, Outlook 2011 won�t sync events or tasks from iCal (in part because Microsoft�s primary design goal with Outlook was to make it work with Exchange). Outlook 2011 also does not support CalDAV.
Setting up Sync Services for Mac:
1. Before turning on Sync Services inside Outlook 2011, be sure to turn off all other 3rd party sync services you may be running in the background. Once Outlook 2011 has completed its initial sync with Address Book, you may turn these services back on again.
2. As a precaution, make a backup of your Address Book contacts. File > Export > Address Book Archive. It�s important to make a backup of your data after you clean it up and before you sync. This way if there are problems you can erase and import the clean backup file.
3. In Outlook 2011, open Outlook Preferences by clicking Outlook > Preferences
4. Click Sync Services and select Turn on Sync Services for Contacts. Outlook 2011 does not yet support sync for iCal.
5. Select the accounts you would like to sync, (i.e. Address Book or MobileMe). Note that Outlook 2011 does not support MobileMe calendar or tasks sync at this time.
Troubleshooting Sync Services for Mac:
The above steps are really quite easy, however, many users have complained that syncing does not occur after following these steps. Here�s a few troubleshooting tips you can follow in the event this happens to you.
Important: Be sure to back up your Address Book and Outlook Contacts before testing any of these Troubleshooting steps.
Turn on iSync
1. Launch iSync, located in the Applications > Utilities folder
2. Open preferences window in iSync Application Menu
3. Check �Enable syncing on this computer�. Sometimes this option seems to be disabled or you can�t check or uncheck this option after starting iSync. In this case, wait for iSync to complete the sync process and then the option will be available again.
4. Reset Sync History. Important: If you are using the new MobileMe Calendar, resetting sync data is not an appropriate troubleshooting step to solve calendar sync issues. Instead, please see Troubleshooting new MobileMe Calendar issues. If you�re not sure how to tell if you�re using the old or new MobileMe Calendar, see this article.
Delete Plist Files
1. Force quit all applications currently running.
2. Go > Home > Library > Preferences
3. Search for all files containing �com.microsoft.outlook.XXXXX.plist� drag these files to the Trash
4. Search for the file �com.microsoft.SyncServicesAgent.plist� and drag this file to the Trash
5. Start Outlook
6. Tools > Sync Services and confirm that �Turn on Sync Services for Contacts� is checked on
Close and Re-Start Sync Services Agent
1. Force Quit Outlook
2. Applications > Utilities > Activity Monitor
3. Look for the Sync Services Agent under Process Name
4. Highlight this process and click Quit in the upper left
5. Close Activity Monitor
6. Re-Start Outlook
I plan to upgrade from 10.4.11 to 10.5 on my PM G5. Will I have to reset any of my wireless net work settings after upgrading to 10.5.
Currently running wireless with an Airport Express and a wireless printer.
Something has happened/changed on my iMac whereby my system locks up so tight that I cannot force quit anything, or do anything else to the system. My only option is to manually reboot.This started last week and I thought I had removed/uninstalled the offending program (iStat Menu) but tonight my system did it again.Any good place to start to keep/start troubleshooting?

It does not come up with the "mirror the display" option in the displays section of the system preferences. Is there a way to troubleshoot the Mini DisplayPort to see if it's working? I downloaded the firmware patch with the Mini DisplayPort to VGA Adapter hooked up to the projector but it was unable to install it since it said that the Mini DisplayPort to VGA Adapter was not detected! I'm thinking that there may be a malfunction to the Mini DisplayPort... Is there any way to check it? I tried 2 different VGA cables. The only thing left would be an issue with the adapter.
View 7 Replies View RelatedIs it possible to reset the total bandwidth used for downloads and uploads in iStat pro via an applescript?
I use it to monitor my internet usage since they cap it at my school to a couple gigabytes a day. Since I went over once and was given a warning, my second offense would be no internets from anywhere from a week to a year.
I would use the application Lingon to automatically run the applescript every day at midnight.
Right now the only way to reset the counter is to restart my computer which is bothersome and time consuming
If anyone could point me in the right direction as to the file it uses to store network usage info I could probably figure out how to write the applescript myself.
