Why do hot corners break every time I wake from sleep?

Every time I open my computers, my set hot corners have stopped working. In the settings, they are still there, but I have to either change the settings and change them back, or use the terminal command 'killall Dock' to fix the issue. It's quite annoying to have to do this every single time I turn on my computer. Does anyone know a fix?

I have this same issue - after coming back from sleep hot corners stop working - this is a constant problem and I think having to type "killall Dock" is NOT a solution. I also have a rMBP with 10.8.2

Mac Pro restart every time it wakes from sleep

I wonder if anyone has this problem, it is not a big one but annoying. Every time I wake my Mac Pro from sleep it restarts, why is that and can it be fixed? Or there is something wrong with this model?
Model info:
Model Name: Mac Pro
Model Identifier: MacPro3,1
Processor Name: Quad-Core Intel Xeon
Processor Speed: 2.8 GHz
Number Of Processors: 2
Total Number Of Cores: 8
L2 Cache (per processor): 12 MB
Memory: 2 GB
Bus Speed: 1.6 GHz

It is big if the hard drive directory is corrupt in the process.
It was common when 2008 first came out, there is/was a firmware update to address this - and a long thread from March era 2008.
Underpowered UPS can also cause this behavior.

"Connection lost" every time I wake from sleep

I bought my MBP with the wireless mighty mouse and for the past 2 or so months I've had no complaints about the bluetooth connection.
Now, every time I wake my computer from sleep the square comes up saying "Connection Lost" at the bottom center of my screen then about 5 seconds after my mouse pairs again.
Why's it doing this? Never did before...
I' not too sure if I'm being to nit-picking or a perfectionist but it just didn't do it before.
Am I crazy or does everyone's do this?
Thanks
-Mike

Hi MIke:
I do not have a similar configuration (I rarely turn mu desktop iMacs off). When I do shut them down, the wireless devices are connected automatically.
However, if your mouse does pair, I would try "normal" troubleshooting as that could possibly cause additional problems.
Barry
P.S. I am also curios about anomalies myself!

Since upgrading to OSX Mavericks, my mbp retina will lose wi-fi every time it wakes from sleep.

When waking from sleep, my default home connection is lost, and it usually cannot re-connect until I turn off and back on wi-fi.

Hi. I'm experiencing the same problem, but it's on a 2007 iMac.
When it wakes from sleep, it does not connect to the preferred network. The preferred network is visible, yet when we select it, it asks for the password again -- which I know it is entered correctly -- but the password is refused. A full reboot is required for it to work properly.
It's an iMac, mid 2007, connecting to a Time Machine, using WPA/WPA2 security. All other devices (eg, iPad, iPhone and an other iMac) do not have this issue.
Workaround: I don't let that iMac go to sleep.
Speculation: It's as if when it wakes from sleep it thinks it a different type of security setting
I have not yet found a proper/permanent solution.
Note: I do have TrendMicro Internet security installed, but it is also on the the other iMac and I have tried it with it off and the problem still occurs, thus I doubt it has much to do with it.
Puzzled,
Mike.

Macbook Pro takes long time to wake from sleep

Hi, I have recently purchased the latest Macbook Pro (Mid-2012, not the Retina display version), and I've noticed if the Macbook is left switched on, with the lid down and not plugged into the mains, it will take a long time to wake from sleep. I've looked for similar posts, and everyone describes it as a long delay, but for me the screen is greyed out (but transparent) and a process bar appears, which fills up and then the display loads properly, but it takes a further 30-50 seconds to activate things like the mouse and wifi etc (it feels like it has completely frozen).
Has anyone experienced this and is it normal? I looked up standby mode, but am led to believe this is only with the retina display models, so am a bit worried.

Hi Thumbnut,

What are the normal Boot time?/Wake from sleep time? for MB?

Looking to buy a MacBook for my wife to replace her old Dell D-420. The Dell still works fine but takes forever to boot and to wake from hibernation. I was given an old iBook a few weeks ago and was amazed at how fast it woke from sleep mode (the boot times were pretty snappy too). So my question is. What is the "normal" wake from sleep time on a MacBook? How long does a cold boot take?
BTW: Steve isn't going to surprise us with an updated MacBook next week is he??
Thanks
Soon to be MacBook owner.

lancia is right- 56 second sound about right, my 2.0 GHz MacBook boots in about 49 seconds.
If you want your MacBook to boot up faster, you can reset the PRAM (parameter random access memory). What this does is that it resets all the devices it searches for when it starts up: forgets about them, literally
To do this, press down the command (the buttons next to the space bar) , option, P, and R keys at the same time when you turn on your MacBook. Press these keys until you hear the tone a second time. Make sure to do it quick, because after you hear the tone it won't work.
Hope this helps,
Wookams
To your BTW question:
Almost certainly not, but I still recommend waiting a couple months extra because Apple notebooks usually update themselves every 200 days or so. I was disappointed from learning this, but hey...

MacPro running Tiger 10.4.11 reboots every time after waking from sleep mode

Whenever I wake my MacPro from sleep it now reboots as though it was shut down completely. This worked fine last week and only started happening yesterday. Any advice appreciated. Thanks.

Try a PRAM reset:
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

After installing Yosemite, my macbook air crashes every time it wakes from 'longish' sleep

I installed Yosemite. All seemed to be fine. But if my MacBook Air (mid 2012) goes to sleep due to inactivity (or if I close the lid), when I then wake it, it restarts and then gives me an error message saying that something went wrong and it had to be restarted. If I choose 'Sleep' from the menu and then immediately wake it again, or close the lid and then open it within a few seconds, it's fine. So perhaps it's a longer term sleep/wake period that is the problem? Has anyone else experienced this?

Further troubleshooting for my situation confirm that there is a conflict between having external three conductor 1/8" audio jack plug into my MBA at the same time when having thunderbolt HDMI cable plugged into external HP display going to sleep is fine however on wake there's a conflict between the audio assignment of these two devices causing an OS X crash where keyboard entry from the MacBook Air is no longer feasible to log into the system forcing a hard powerdown reset.
Interesting tests prove if you plug-in Apple earbuds with the four conductor 1/8"'audio plug into the MBA audio port there is no problem as OS X likely sees these earbuds as a smart device versus a standard three conductor audio cable plug to external speakers or not. Several different Three conductor audio jacks/cables were tested and the crash upon sleep wake continued.
After three conductor audio jack is plugged in but the HDMI is removed from thunderbolt then you wake the computer there is no conflict and it functions as intended No crash full functionality of all keyboards and mouse and put work correctly.
Likewise conversely if you unplug the three conductor audio jack and just leave the thunderbolt HDMI external display plugged in upon wake everything functions as intended so it's not specifically related to external display or audio cable but when both are connected that the conflict crashes the system Upon sleep wake.
Be reminded this configuration and scenario work perfectly fine prior to Yosemite OSX 10.10 update.
Even went to the sound audio settings and forced audio output two headphone audio and crash and still consistent one HDMI is connected to thunderbolt port waking from sleep.
Likely some trimming issues going on with the new Yosemite to do with audio assignment and potentially AirPlay. AiPlay was not being utilized however I have to Apple TVs that are in the background with AirPlay showing and the audio configuration settings but they were not being utilized at the time of these crashes.
This issue has no variance regarding MBA screen is open or closed when putting to sleep and wake initiated by typing keyboard key.

Why does the menu break every time I adjust it?

The menu drop downs seem to lose functionality as I change it. This only gets worse each time I publish/preview it.

Problem solved: I have been using Walnut for Firefox ver. 2.0.28 theme. For some reason this has been causing the problem. Started FF in Safe Mode, and the slider problem disappeared. Then proceeded to re-enable the Walnut theme: the problem reappeared. Disabled Walnut theme and reenabled all my other add-ons (about 6 of them). Still no problem. So, clearly there is a problem with the use of Walnut theme in FF ver. 32, at least on my Windows 7 installation.
Thanks for all your suggestions and help. Good job, all!

Takes a long time to wake from sleep?

If my 2012 Mac Mini has gone into sleep mode for some time it takes forever to wake up and become responsive again. There is also a lot of disk activity for some time after it wakes and it is very sluggish.
It is like it has gone into hibernation?
Any ideas?

Checking Disk Utility there are no S.M.A.R.T. errors.
Activity Monitor the top item most of the time is Kernal Task with around 2.5% CPU.
There is 13.18 GB Free Ram and Page Outs are 0 bytes.

Why does my iTunes hang every time when using automatic device detect?

Why does my iTunes hang every time that I connect either of my devices (iTouch-4th Gen, iPod Nano-5th Gen), to my Win 7 (64-bit) PC desktop? By the way, this does not happen if I open iTunes first, and then connect the device. So my workaround was to simply uncheck the checkbox that allows iTunes to start automatically upon device connection. This doesn't fix the problem, but it allows me to synch my device, but it would be nice to be able to have the autodetect work properly, so that iTunes would start normally without locking up on me and freezing. That's what I mean by 'hanging'. My whole computer doesn't freeze--only iTunes.

Hello E
Start with finding the path where the songs are on your PC by right clicking the songs that are missing in iTunes and click Get Info. You should get a window that pops up and in the Summary tab; the path will be there. Then navigate to where it was and see if the files exist. Other than that you can try to search your computer to find those files. Checkout the articles below for tips on finding the missing music, also if some of the tracks are downloaded from the iTunes Store you can download the tracks again by deleting the missing tracks from iTunes and then navigating to the purchases section in the iTunes Store to download them again.

What happens when the Mac goes to sleep (not just into idle mode or display sleep)?
On all Macs:
The microprocessor goes into a low-power mode
Video output is turned off, and a connected display may turn off or enter its own idle state
Apple-supplied hard disks spin down; third-party hard disks may spin down
On portable Macs:
The Ethernet port turns off, if applicable (see note below)
Expansion card slots turn off
The built-in modem, if present, turns off (see note below)
An AirPort card, if present, turns off (see note below)
The USB ports only responds to the power key on an external keyboard (see below)
The optical media drive, if present, spins down
Audio input and output turns off
Keyboard illumination, if a feature of your portable computer, turns off
But see the note about selecting, "Wake For Network Access" in Energy Saver preferences.
Note: Portable computers have no network connectivity when in sleep mode, but can wake if the Energy Saver option "Wake for network access" is enabled. If you wish to use file sharing or don't want to interrupt your Internet connection, you should not manually put the computer to sleep, and you should drag the "Computer sleep" slider to Never.
