Sudden Brrrrrrrr- Noise on MB Pro After Wake

Hello.
After about 2 hours, i come home to my sleeping macbook pro. I open it up, resume my video and suddenly a "brbrbrbrbbr" noise sounds, but nothing comes up on the screen. I can hear it through my headphones too.
I restarted my computer and everything was fine...
I just want to know what this is!

If it is under warranty, by all means take it in for service. If there is a mechanical deficiency, it should be repaired gratis. It does sound like an internal fan problem that needs to be replaced.

Frozen MacBook Pro after Wake

So up until now I have had no issues with my MBP. Oddly enough today I was using Safari and closed the lid while it was running. I opened up the lid and the computer awoke but remained in a frozen state. No keyboard, no mouse, and no spinning ball. The only thing i was able to do was hold the power button to do a hard shut off. I can turn the computer back on without a problem. I have tried changing my power setting so that the hard drives do not go into sleep mode but this hasn't helped. Also did a new install which also didn't fix the problem. Any help would be greatly appreciated.

After update to OS X 10.7.5 on my Mac Pro (2009) USB ports don't work at all after wake up from sleep mode; with 10.7.4 there was (nearly) any problem.

hello,
after update to OS X 10.7.5 on my Mac Pro (2009) USB ports don't work at all after wake up from sleep mode; with 10.7.4 there was (nearly) any problem.
the used ports appear to be "killed"; the unused USB ports seem to work, but the Mac works in slow-motion.
The only "solution" is to restart my Mac.
- SMC-reset, PRAM-reset or repairing user rights had no positive effect; what is the solution - a bug-fix-update???

I have a mac mini (A1283) with OS 10.7.4. Upon upgrading to 10.7.5 it did not start up again. Instead, the light was on and the hard drive did not start up. The light on the connected USB mouse was not lit.
My solution:
Cold start with Command-v pressed.
This should start Verbose mode (see http://support.apple.com/kb/HT1492 ).
What happened on my mac mini was that the grey startup screen with the Apple logo appeared for a long while before the login screen came.
Maybe Cmd-v set open firmware params and fixed some corruption.
Anyway: my mac mini works again.

I just tried to wake up my 4 year-old MacBook Pro after perhaps an hour of inactivity, and it just 'pinwheels' and won't restart. HELP!!!!!!!!!

I just tried to wake up my 4 year-old MacBook Pro after perhaps an hour of inactivity, and it just 'pinwheels' and won't restart. HELP!!!!!!!!!
Semi-experienced user - Western New York.
System was operating nominally until I opened it from 'sleep' mode after ~1 hour of inactivity.
No idea what's going on. I had just installed a Flash Player update [not an atypical occurrence] at ~6:00 PM this evening, but used the system without incident after that. Re-Start attempt does not appear to succeed, the circular pre-OS icon never clears and displays the authorization screen.
Anyone with an idea how to help would be greatly appreciated. We have so much personal and business data on this machine!!!
Thanks!
Jim F.

Press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly to restart.
The fact that you're worried about the data implies that you have no backups, or that you don't have confidence in your backups. Your first priority must be to back up all the data you intend to keep. Ask if you need guidance.

MacBook Pro needs restart after wake up

I recently upgraded the hard drive (to 1TB) and RAM (to 8GB) of my late 2008 MacBook Pro, as well as performed a fresh install of Yosemite. My system has been running pretty fast and well; however, when I put my notebook to sleep and wake it up, it won't run programs. Files won't save, programs will quit before they start, and web pages won't load, and this is after wake up. When I restart the computer after this, it returns to normal working order. I can shut down and restart when I need to, but I would like to be able to use sleep/wakeup when I can (which was working fine when I had Mavericks and the older HDD and memory). I was wondering if this was a problem with Yosemite, as I have been seeing some issues with this functionality with the new OS, or if it is a problem with my new hardware. Thanks in advance.

Step 1
Take all the applicable steps in this support article. That's the starting point for any further efforts to solve the problem. Please read the whole article carefully (some of it is hidden by disclosure triangles) and don't skip any of the steps, including the ones under the heading "Additional troubleshooting." If you don't understand any of the steps, ask for guidance.
Step 2
If you're running OS X 10.8.5 or earlier, 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.
Step 3
In the Energy Saver pane of System Preferences, uncheck the box marked
          Put hard disks to sleep when possible
Step 4
If you don't already have a current backup, back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.
If you use FileVault 2, then before running the Installer you must launch Disk Utility and select the icon of the FileVault startup volume ("Macintosh HD," unless you gave it a different name.) It will be nested below another icon with the same name. Click the Unlock button in the toolbar and enter your login password when prompted. Then quit Disk Utility to be returned to the main Recovery screen.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode. All other data will be preserved.
*The linked support article refers to OS X 10.10 ("Yosemite"), but the procedure is the same for OS X 10.7 ("Lion") and later.
Step 5
This and the next step must be taken as an administrator. If you have only one user account, you are the 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 and start typing the name.
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ Diagnostic and Usage Messages
In the search box in the window's toolbar, enter "powerd" (without the quotes.)
You may see one or more lines like this:
com.apple.message.signature: Platform Failure
If you do see that, and you did everything in the preceeding steps, then you're dealing with an internal hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
Step 6
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that heading, select
          View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down.
You may see one or more reports with a name that begins with "Sleep Wake Failure" followed by a date. Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.

Slow Wi-Fi Reconnect After Wake from Sleep (Macbook Pro Retina Mid 2012)

Hello!
I'm not sure if anyone has experienced this problem, maybe someone out there can help.
The issue I'm having is with Wi-Fi taking a long time to reconnect after my Macbook Pro Retina wakes from sleep. Usually I need to go and reselet the network.
I've gone through some trouble shooting forums and have had no success. I've tried turning off Wi-Fi and turning it back on after a couple minutes and it turns on right away.
Has anyone experienced this problem?
Regards
CJ.

MacBook Pro Retina Mountain Lion + Dell U2713hm hangs after wake-up

This is a more specific description of my problems here:
https://discussions.apple.com/thread/4385171
I use a Dell U2713hm together with a MacBookPro Retina under Mountain Lion. The Dell is connected via the Thunderboldt to DVI-D adapter that is sold by apple. The Dell has a USB 3 Hub. The upstream is connected to the Apple-DVI adapter. I use a mouse and a Logitech keyboard, which are connected to the Dell USB hub.
The display blanks from time to time for some seconds, which is suboptimal and I would be greateful if this could be fixed. But the biggest problem is that the system hangs after wake up. Sometimes the external monitor just stays dark, sometimes I get the login screen, but cannot type since the swapping wheel is shown. I have to reboot the machine.
To me this looks like a USB(3) sync problem.
If there are any ways around this I would be really glad. Is there a way to disable USB3? I also noticed that the speed of components that is displayed in the system profiler depends on the ports I use for keyboard, mouse and camera ...
Thanks!

The solution is to dump the 100€ mini-display port DVI-D adapter that apple sells and buy a mini-Display to Display-Port cable for 6€. No crashes, no annoying interruption of the display (which I had several times the day for 2 or 3 seconds). There are very short interruptions now, but it is much better than with the apple adapter. The apple adapter needs a USB port, which is not necessary with the simple cable.
As for the monitor: Burn In, otherwise great. The burn in can be erased via monitor menu but should not be there in the first place.
Hope this helps.

Force external drive to remain in stand by after Wake up

I have a WD My Book external drive connected to my iMac 27" via USB 3.0
The drive is initially in a stand by mode (drive doesn't spin, it's visible in disk utility).
Now when backup script starts, it first checks to see if drive is mounted. If it's not it then mounts it (drive begins to spin), then the backup process starts, and lastly the disk is ejected (drive stops spining, it's again in standby)
All this works, however my problem is when my mac wakes from sleep, drive automatically starts to spin and is mounted. I want the drive to always remain in stand by except from when it is manually mounted.
How can I achieve such a thing? I have tried the folowing:
Disabling the USB Mass storage: requires restart and results in all USB ports being disabled, which is unaccepted
Setting the drive to "Power up in Stand By feature" with linux command "hdparm": Even tho hdparm says the disk supports this feauture, I've got I/O error
Setting the jumper to proper position to enable PUIS: the white lid is switched on, but nothing happens (not visible in disk utility)
Adding the line in /etc/fstab to prevent auto mounting, which partially works. (drive still spins after wake up)

Thanks for your reply.
There is only the spinning wheel in the finder sidebar when it is actually backing up.
Not after it has finished according to the progress bar in TM Preferences. When that has finished, the Hard Drive just carries on gurguling and ticking.
Until I drag the volume icon to the trash then it stops. AND I have just noticed the wheel starts spinning in the finder window after I have done this and it starts backing up again. It does not eject but I get a notice saying " Is in use could not be ejected. Try quitting applications and try again." (well I do have applications open). Then after this back up all is quiet. But the cycle starts off again after the next sheduled backup starts.
I can not see anything called backupd in activity monitor while the noise is current.
The only activity seems to be from "Activity Monitor" "Finder" "System Preferences" "SystemUIServer"
In 'Console' under All Messages it says Backup Completed succesfully. followed by
kernel............SetCryptoKey R: len 32, idx 1
Sorry I can't make things any clearer.

Macbook Pro wont wake from sleep

My '08 MacBk Pro wont wake from sleep. This has happened several times since I installed Lion. In the past I have simply clicked several times on the trackpad until it woke, but on several occasions it actually shut down after entering sleep mode, (It went to black screen, the little pulsing sleep light was dark and I got no responce to clicks on trackpad or keyboard). When this happens I can usually re-start the Mac with a hard re-boot to resolve the issue. This time however, I can't get the computer to turn on. I've tried pressing the power button once, and all that happens is that the sleep light blinks once along with a the normal whiring sound you hear when the computer is ramping up, but this lasts only a second and then it goes back to black screen/dead Mac. I also tried holding down the power button as I would for a hard reset at which point I get several blinks from the pulsing sleep light and then nothing. I also tried unplugging the cable, removing the battery and pressing the power button for 5 seconds, then reconnecting battery and cable and pressing the power button, (I got these steps from an article posted here on the furums). BTW, I have disconnected all external drives, etc. before trying any of these steps. Please let me know if there's something else I might try to revive my Mac.

Follow up: I took the MacBook Pro for repair and the tech found that the logic board was damaged - probably due to so many hard resets I had to perform to get the machine to load when starting it up after shutdown or restart. I replaced the logic board, (Very expensive) and its been running fine for 3 days. However, the freezing problem has just started again and I'm worried that having to perform a hard reset to get the macbook to load will cause more damage.
The problem that's occuring is as follows: When I start the computer up after shutdown, or sometimes after restart, the desktop fails to load and the spinning color wheel appears. I can see the dock and the main upper toolbar but my desktop is blank and my external hard drives do not load. I can't make any selections with the cursor because of the eternally spinning color wheel, so my only option is to perform a hard reset by depressing the power button until the unit shuts down. When I start it up again the system loads correctly. I have tried ejecting my external drives before shutting down, but this doesn't make a difference. This problem started when I installed Lion OS and got continually worse until the computer finally shut down for good and I had to replace the logic board. Now it's starting to happen again.
Has anyone else experienced this problem running Lion on a MacBook Pro early '08? If so, please help me find a solution for the freezes.

Airport issue after wake from sleep (lion)

With 10.6, this was not a problem. With Lion, very often after wake up from sleep mode, the system is unable to reconnect to my airport extreme base station. Killing the prefs in the library did not help. Any suggestions?

My wife's Macbook has EXACTLY the same problem and I've been through dozens of suggestions trying to fix it and the problem still persists.
The problem started right after I upgraded to Snow Leopard but also installed an Airport Extreme router and WPA2 wireless encryption. I've deleted all the networks, changed the order to put the Airport as the highest preference, deleted all the keys on the keychain, ran DiskUtility, all to no avail.
I'm not sure if this is somehow related to the Airport Extreme or occurs with any router. Also, have another MacBook Pro (unibody), and it does't have this problem connecting to the same Airport Extreme.
The other factor is it is intermittent --- and doesn't always fail. Rebooting the Macbook or the router will get it to re-connect, as will shutting off and turning on the Airport several times. But that's not a solution to the problem.
Apple needs to pay attention to this as many people are now reporting the problem.

Left USB-Port dead after wake from sleep. Just restart helps.

I hoped Apples keyboard-Update today would solve my biggest hate-bug in this buggy POS called Leopard. It didn't.
As usual on my Leopard-Macbook Pro, no device will work on the left USB-Port after I waked the computer from sleep. Just a restart helps. I hoped this update to solve this, because it replaced among others "IOUSBFamily.kext".
Terminal gives a timeout error for the internal USB-Hub after wake from sleep. I assumed this should be related.
I'm really angry now.
When will Apple solve the most urgent problems in Leopard?
Was 10.5.1 just smoke and mirrors to make (fool people into...) people upgrade who intended to wait until the first maintenance-update?
Was Leopard Apples attempt to make Windows-Users more comfortable by putting in some heavy extra-bugs and blue screens?
FIX IT FINALLY! And f... don't wait for Macworld to release 10.5.2. It's desperately needed and the current state of Leopard will leave some people very sad at christmas after getting their first Mac. First impression counts and many more peoples first contact with the Mac will be at christmas...

Apple knows the problem and for some reason they are stumped on fixing it. this is so bad I can't believe it. On my macbook pro with Leopard installed, USB left port is dead after sleep. Only restarting can power it back up. I have to restart every day to use my external hard drive for time machine or when putting my flash drive in the port.
Come on already Apple. This is a SERIOUS, SERIOUS problem.
Fix it.

Reconnect NAS after wake up

Hi,
If I set my Macbook Pro to standby mode and let it wake up again, the connection to the network drive in my network attached storage is lost. I have to reconnect manually using the apple-k command.
Is there a way to get these drives reconnected after wake-up automatically? This is definitely no issue with Windows - I wonder why it should not be possible on Mac.
(I am not talking about rebooting the machine, but about waking it up from standby - reconnecting automatically after a reboot can be done easily by adding the drives to my startup objects).
Thanks
Simon

Hi Tomasz
One question;
Do you speak about an external soundcard which is connected via USB to the notebook or do you speak about the inbuilt Realtek soundcard!!!
I know about a similar sound issue on Vista OS.
I have read in the Microsoft knowledge base about similar problems;
