Wake from sleep - Computer connects half speed or less

After the last Airport update, my wake from sleep connection issue went away. Now, two weeks later, it is back.
I have no hope that this message will accomplish anything other than making me feel a little bit better.

I should probably add I have tried various settings in Energy Saver with the same results. I have also checked the Energy Saver schedule to make sure there isn't anything there. The only two login items I have are the iTunes application and the helper application. I have repaired permissions as well as checked my startup disk and its ok. When I installed Yosemite 10.10 I erased my drive and did a fresh install hoping that would do the trick but nope.
I've been using macs since 1992 but I cannot seem to figure this one out.

MBA won't wake from sleep while connected to VGA Display

Since a few days I'm using a VGA Display connected through the official Apple Mini Displayport - VGA Adapter. However, when I put my MacBook Air to sleep and then close the lid (otherwise closing the lid will just continue on the display). Keeping the monitor attached, it won't wake from sleep anymore. Disconnecting the adapter at that moment won't make any difference. What troubleshooting steps can I make?

I usually...
Take out the charger
take out the battery pack
reinsert the battery pack
Then click the power switch
(if you have low battery I'm sure it would be a good idea to plug in the adapter again

Mac loses internet after wake from sleep, still connected to router

Hi All,
So, I see similar threads, but I'm not sure if this is the same problem. Here's what happening:
-When I wake my Mac from sleep it usually (but not always) loses its internet (but not wifi) connection.
-The loss happens 10-15 seconds AFTER it wakes up. If I go to Safari/Firefox right after it wakes up, I can bring up webpages fine for about 10 seconds. Then, suddenly, pages stop loading.
-The wifi stays connected (I have an airport router) the whole time, and if I go to the airport utility, everything looks fine.
-I know this is not a problem with my internet or my router because I have tried opening web pages on both my iPhone (connected to wifi with cellular off) as well as my PC laptop (I only have it for one program that the company does not make for the Mac and I need for work, haha), and both browse the internet just fine even though my Mac says there is no internet.
-If I restart my Mac, the internet works fine. This is a simple fix, however it's also annoying to have to do it all the time.
-This is happening in different locations, not just on my wifi. It happens in coffee shops, hotels, and airports too.
-Not sure if this is related, but I have also been getting messages in iTunes saying that I need to authorize my computer or apps will be deleted.
-I completely deleted Norton, as I had a hunch it was responsible for this problem (since the internet was disconnecting right after getting an "add location" message from that program). However, even with it completely off my computer, I'm still having the issues.
Any suggestions???

What Mac OSX version are you running? "iOS 8.2" as currently shown in your profile cannot run on any Mac computer, only Apple mobile devices.
If your computer has automatically connected to a lot of networks, say, during travel, that might hinder waking as the computer looks for what networks it remembers. Go to System Preferneces > Network and select your wirelss connection from the left-hand pane. Then click the "Advanced" button in the main pain. That will show the list of networks you Mac has stored:
There could be a lot. Clear out all networks stored there except those you use on a weekly basis. The little box with the "-" icon clears unwanted networks. Restart the computer and see if thising work better.
-I completely deleted Norton, as I had a hunch it was responsible for this problem (since the internet was disconnecting right after getting an "add location" message from that program). However, even with it completely off my computer, I'm still having the issues.
Download and run Etrecheck, a safe way to post a snapshot of your config without revealing any personal information. I'm concerned you did not get all of Norton, or have some other dreck like CleanMyMac or MacKeeper lurking.

Display no longer wakes from sleep after latest updates

G4 Quicksilver 933, nVidia Ti, 1.5GB, 20in Cinema Display
I applied the latest updates that were pushed out recently (10.5.2 and the "Leopard Graphics Update") and now my Apple display will not properly come up when I wake the box from suspend.
That is, it starts and runs fine, but if it goes into sleep, upon waking it will (sometimes) flash the contents of the desktop, and then go black. The litte green light is on. Happens from a logged in session, or from the main login screen.
I have to hit the reset or power button (or login via SSH and issue a shutdown) to get it to work again.
I only have a single monitor.
I tried:
o Powering the monitor off and on, both from the switch and by pulling the power cable
o Pulling the DVI cable and reinserting it
o Resetting NVRAM
o Re-applying both the 10.5.2 combo installer and the Leopard Graphics Update 1.0 in order
o Waving a magic wand... I mean, fixing permissions
o Changing the display resolution a few times
o Running fsck a few times (only because all these unclean shutdowns are making me nervous)
o Hitting the "Detect Displays" button in the Displays Prefs panel...
Aha! Hitting that button causes the display to flash and then go dark. I have to power cycle the unit to get the monitor to come up again.
I do have the special build option of the faster video adapter which was available all those years ago. It's quaint now, sure, but it was a fast card back then.
I'm stumped. It's surprising how something like this can turn a perfectly reasonable desktop into a boat anchor.

This Discussion is marked as Answered, but with my apologies to the other respondents, it is NOT. There is a problem. The software/hardware do NOT work as they are supposed to. Apple needs to address this problem immediately. Mac Book Pro will not wake from sleep when connected to a Cinema Display 23". The problem lies in the most recent operating system updates. Before the update the products worked as advertised, since then they do not. Period.
With all due respect, I am the one who posted this, and I marked it "answered." Yes, there very well may be a problem with the Leopard Graphics Update 1.0 (what a mouthful! I dub it "LGU v1.0" from this point on.), but this is so far only a hypothesis.
I found an immediate workaround which suits my purpose. If this does not suit the purposes of completely foreign (to this discussion) symptoms related to Intel-based Apple laptops and external displays, then so be it. I recommend splitting off your own symptoms to a new thread.
Certainly, my reading of the symptoms described after I posted mine mostly do not sound like what I ran into at all. For example, I never once said that my computer had problems waking from sleep. I said the /display/ had problems waking/starting up after sleep, and this is probably related to the "detect displays" mechanism that the OS uses to find attached displays when it comes out of suspend. Even if this is my misunderstanding it does not matter, since this is how it comes across to a reader. This may indicate that someone may want to clearly and carefully describe /exactly/ what they are seeing, and the steps they took in order to come to any conclusions they might have.
This will help Apple, and it will certainly help others that search these threads with their own similar but different issues they need solved.
If there is a common reproducible issue related to displays and the most recent update(s), then Apple already knows about it, or soon will. As far as my immediate needs are concerned, this is answered.

Jump Desktop on Mountain Lion - Won't wake from sleep

Installed Mountain Lion. Now it will not wake from sleep when connecting from my iPhone 4 or new iPad when connecting via Jump Desktop. Screen sharing is turned on and gmail account and password are all correct. No problem connecting as long as my MacBook Pro is awake. With Lion, there was no problem waking from sleep when connecting. Anyone have the same problem -- or a solution?

Had the same problem, as a work around tick the
'prevent computer from sleeping automatically when the display is off'
button in power settings
Although not in sleep, it means the screen is off but still can be controlled remotely
worked for me

OS X 10.7.3 WiFi Update for iMacs and Wake from Sleep Problem

http://support.apple.com/kb/DL1501
Apple has released a software update for those suffering from the iMac wake from sleep/wifi connection issue that resulted from updating to 10.7.3. It fixes the problem for me and several others. For those still suffering this issue, download it and see how it works!

To answer my own question it seems a workaround is to wake the iMac up using the power button rather than the keyboard. The WiFi reconnects this way.

Airport issue upon wake from sleep

When my mac pro wakes from sleep it connects to my preffered wireless network but it has some serious issues and doesn't work. When it restarts the airport icon shows connected, but mysteriously shows a weak signal and when I try to do anything that needs to talk to the network it fails. The only way to fix the issue is turn airport off then on again and hey presto I'm back on a full signal and can surf n stuff.
I'm using a 1st gen Airport Express N basestation, which works fine as I have 5 other macs in the house (non a mac pro) that don't have the issue.
Looking in my logs i see a few interesting things, it looks like when the system is woken up it sets the country code to X3 and then fails to get a proper link. When I restart airport it sees the network uses GB as the country.
I can't be the only person with this problem.

I lose network connection after MacBook Wakes from Sleep

I upgraded to Mountain Lion on my 27" iMac and 15" MacBook Pro. iMac is doing fine. MacBook Pro, however, when it wakes from sleep, seems to have the network untility crash.
So the computer wakes from sleep, and the little status bar radar thing does its little sweep and doesn't just go solid. . If I click on it, it shows my Airport as connected, but after clicking, it freezes. the second to the bottom bar goes solid and the cursor becomes a spinning beachball. If I open system preferences, and select network, it freezes. The only way I can seem to get back on line is to reboot. I have an airport extreme with an older (g) airport express that I use to beam music to my stereo. The MacBook Pro is about 2009 vintage—you can still get to the battery, HD and memory—and the iMac is a bit later. One of the first 27" models, not quad core.
Anyone else having this problem? What more info would you need to help resolve? I'm a novelist and this is killing my productivity.
Thanks,
Steve

Try the basics first:
Change your router channel number. Most times this works & is all you have to do.
Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.

Display Changes Resolution When Computer Wakes From Sleep

I have a MacBook Pro bought in May of 2006. In the last year, this problem has been getting progressively more annoying to me. When the computer wakes from sleep (not every time, but most of the time) the screen will flash blue, then reset the resolution to 640 x 480, I think. To fix it, all I have to do is go to System Preferences and change the resolution, but when I do that, it pops up two windows, like it thinks I have a dual display set up. To fix this, I always click 'detect displays,' and it fixes it, but the next time I wake the computer from sleep, it does it again. This isn't really an urgent problem, but I would expect my computer to behave a bit better for me.
Thank you in advance for any aid you might give me.
Lisel

Hi Lisel. I have a similar age MacBookPro that does the same thing. I don't really know how to fix it I'm sorry, I wish I did cause it's annoying. I just thought I'd let you know you're not the only one with this issue.
Basically, for some reason it thinks it has two displays connected, even when there isn't. To stop it being a total pain, make sure when it does come up with the two Display Pref windows to set them both to 1440x900, at least then when it does go dual display it won't be 640x480 and you can still read stuff.
I've also left the Display Pref icon on the top tool bar (next to the AirPort and Bluetooth and stuff), so I can just click that and Detect Displays. When it does that it figures out for itself it doesn't actually have two displays connected and so goes back to normal.
I know that's a workaround and not a fix, sorry. I'd be keen to know if anyone else has any better solutions:)
Thanks,
Mark.

"Connection Lost" on boot + Wake from sleep black screen and racing fans

When my iMac boots, I receive a "Connection Lost" symbol indicating the Bluetooth Mouse, yet Bluetooth is not turned on. How do I get rid of this? I have been having the "wake from sleep" issue for the last few weeks (black screen, racing fans) and wonder if this is somehow related.
I have reset pram, nvram, trashed the com.apple.PowerManagement.plist file, unplugged the computer, repaired permissions, etc. to no avail. I have to power down with the power button and reboot every time it goes to sleep. This is getting very annoying. Any help would be appreciated. Thanks.

I used to have a similar problem when I used a Kensington Turbo Mouse Pro (not wireless). The computer would wake from sleep in the wee hours on its own and in the morning it would be so hot I could fry and egg on it. The Mouse was obviously so sensitive that any slight vibration would trigger a signal to the computer and wake it up.
Also I got the connection lost message on startup even though Bluetooth was not turned on. I figured that for some reason the Turbo Mouse was not discovered in the startup process. When this happens the System gives a warning that since no mouse was connected, I would have no way to control the computer and it advised me to turn on a Bluetooth mouse. It would then search for one for a minute or two. I just unplugged the Kensington Mouse and plugged it back in and I would usually get a message informing me that a mouse had been detected and the startup process would continue.
As soon as I substituted a Mighty Mouse for the Kensington Mouse, everything has been just fine since. I also uninstalled the Kensington Mouseworks software and started using USB Overdrive which gives far more options and a far better Mouse feel than the Apple Mouse settings.

Audio volume low when computer wakes from sleep - os x yosemite

I've been having an issue ever since I upgraded to OS X Yosemite, where the audio volume coming out of my external speakers is extremely low after I wake my computer up from sleep. The only resolution I have found is restarting the computer. Once I do that, the audio volume is great. If I were to boot up my computer after it has been completely shut down, the audio volume is also great. The issue only occurs after sleep. Anyone else having a similar issue? Is there another fix besides restarting the computer?
Speakers: Bose Companion 2 Series II (these are wired, not bluetooth)
Computer: Mac Pro - late 2013 - running Yosemite

This is a BUG. It has been submitted to engineering many times - unfortunately Apple has not done anything about it.   We have 5 Mac Pros, all 5 do the same thing after updating to Yosemite.   The PRAM / SMC reset is useless - we even installed a fresh OS on one of the machines (a suggestion of the level 2 Apple tech) same problem.   Clearly this is a system level bug.   Only way to get it resolved is to keep pounding the bug report site with requests.     The squeaky wheel gets the oil.   The problem is 100% repeatable on the machines that exhibit the bug.
In the mean time set up an applescript with this command and it will reset the sound - do not include the brackets :
<do shell script "sudo killall coreaudiod" with administrator privileges>
Run it every time you wake from sleep and you won't have to deal with the problem ever again.
Pretty lame that Apple has not fixed it even though the problem appears to be pretty widespread.

MacBook won't automatically wake from sleep after flipping computer open.

The only way my computer both goes to sleep and wakes from sleep is by clicking on the Apple icon and putting it to sleep before closing the lid and by pressing the power button after opening the lid. If I just close the lid without first clicking on "Sleep" under the Apple icon, the computer will continue to run and the Apple on the lid will continue to be lit while the sleep indicator light does not go on. If I just open the lid and do not press the power button, the screen will continue to be black and the sleep indicator light continues to glow. I'm not sure if I reset a system preference or something by mistake, but is there a way to fix this? Or is this an indication of a bigger problem?
Additionally, when my computer is asleep and I unplug my charging iPod, it wakes from sleep (the sleep indicator light goes black while the Apple on the back of the screen lights up). Is this an indication of a bigger problem?
My computer is only about 7 months old, so I am a bit worried if it is starting to show wear and tear already. Thank you for your help!

You're welcome to the Forums.
Go to System Preferences>Energy Saver, and set a time for your System to sleep.
Set both sliders to 10 or 15mins to nod off, when Inactive.
It's never a good idea to plug in or out, while the Computer is sleeping. If someone pokes at your ear while you're sleeping, you'll wake up too.

BUG: Sandisk USB flash drive in "half-mounted" state after wake from sleep

My Sandisk Cruzer Crossfire 4GB Flash Drive is left in a half-mounted state after wake from sleep. The Finder believes the drive is still mounted, the icon is on the Desktop. However opening a file on the drive, or trying to eject the drive, results in a long beach ball, followed by a message that I removed the drive without Ejecting it first. The same drive continues to work fine on my Tiger machine, and on PCs.
Bug Report:
Setup:
Macbook 1st Gen (2.0 Ghz)
Mac OS X Leopard 10.5 Clean Install
Sandisk Cruzer Crossfire 4GB USB Flash Drive (in either port)
Repro:
Plug in the drive.
Close the MacBook to put it to sleep
Reopen the MacBook
Result:
The lights on the flash drive never light back up after wake from sleep. Navigating the drive, or trying to eject it results in a "you removed the device without ejecting it first" message.
Expected:
Drive should still be mounted and accessible after waking back up.

It may be a design flaw in the device. Mac OS X does a lot more power management than most other OSes, including tearing devices down to little or no power during sleep. It is possible that the device simply misbehaves due to corrupted memory state or reports a substantially different GUID or something similarly bizarre upon wake. (Okay, that last one wouldn't technically be a power management issue....)
If it doesn't have any problems except when sleeping the system, I would just make sure I unmounted it before putting the machine to sleep and wouldn't worry about it. Maybe check with Sandisk to see if they have a firmware updater for the device.
