Mac Pro :: OS X Mavericks (10.9.4) Stops Disk I/O When Display Sleeps
Aug 28, 2014
I have a new Mac Pro (cylinder) running OSX Mavericks (10.9.4, up to date) which has an issue with power saving and disk I/O.
I have my display set to sleep after about 15 minutes of inactivity. I have turned off other power saver features. When this happens, any jobs I have running stop -- in this case, I was running a "dd" off a USB-mounted SD disk, which I wanted to run over night. Instead, it stopped and I had to restart it.
In a non SD-disk based Mac, this isn't a problem. The system just turns the display off and everything else runs.

I put my MBP to sleep. Opened the lid back up about an hour later and it was in Deep Sleep mode. I had to press the power button and wait for it to restore settings before I could do anything (greyed out screen, progress bar, etc).
Battery was still at 82%.
Anyone know what's up with this or have this happen with their computer before?

I've set my energy saver preferences to put the display to sleep after 10 mins and the computer to sleep after 15 minutes of inactivity. The display sleeps but the computer always stays on, whether on battery or A/C. What's the problem here?

i've been having some problems with my 27" iMac (2011). I was playing a game (Diablo 3), when suddenly there was a kernel panic, so I had restart my computer. I started the game again, and there was another panic. After that, every time I login everything works great for 5 minutes, then the screen goes black, and it just stays there, nothing happens. I've tried restarting the computer many times, but it just keeps crashing.

iMac 9.1
2.66GHz
8GB RAM
Running Snow Leopard 10.6.8
Trying to download Mavericks, the download stops every time at 1.03GB, and clicking retry doesn't start it.
I get the message "The application you tried to download could not be downloaded. Check your internet connection and try again."But if I click Cancel, and then restart the download, it works perfectly again up until 1.03GB.
So I'm a little unconvinced that it's a problem with my internet connection, considering I have full access to the web and clicking retry shows it working and connecting.

When I attempt to verify or repair disk permissions the process starts and then stops. The following message appears in a drop down message box: First Aid failed. Disk Utility stopped verifying (repairing) on G4HD because the following error was encountered: no valid packages. My disk verifies in working order. I have used DU from the installer disk and obtained the same resulting error message. I have run Tech Tool Pro's optimization and maintenance sequences. I reinstalled Security Update 2008-003 PPC thinking it might have been the problem. This permissions verification/repair problem and a problem with my firewire external HD and iPod failing to mount started after I installed the security update. (I am not asking for help with the firewire drive problems here - that is for another forum) I am running 10.4.11 on a G4. I guess my next step is to reinstall 10.4.6, the version I bought

I have just replaced the hard drive in my iMac due to buying it second hand with a faulty hard drive. (little to my knowledge)
When i reset the computer to factory settings and cleared the original hard drive and tried to install Mavericks it would always stop downloading at 1.02gb and say calculating. After clearing caches and preferences rebooting and trying again the same thing would happen every time. Now I have had a new HD installed into the iMac and the same issue is happening. What could be causing this? I have been on the phone numerous times with Apple Support and no one seems to have any clue why this would be happening. I have also installed all the updates available for this computer.
Here are the specs of the iMac
Model Name: iMac
Model Identifier: iMac10,1
Processor Name: Intel Core 2 Duo

I get the message now and then when Time Machine fails to backup to external disk:
"Time machine could not complete the backup. Unable to complete the backup. An error occurred while creating the backup folder."
This periodically occurs even though the previous hourly backup was OK.

It doesn't matter if I set the preferences to check automatically, every 1 minute, every 5 minutes, etc. Mail just stops retrieving, and even more aggravating is the fact that the Activity monitor runs at the specified interval, implying that my mail is being checked. And yet, if not for checking my email on my iPhone, I'd think everything was fine, it's just a particularly slow day. When I see that in fact I've gotten a number of emails, I check my Mavericks Mail manually, and still nothing comes in. It's only upon deactivating all my accounts and then reactivating, or quitting the app and then restarting that I get all the mail I've already gotten on my iPhone. This is pretty infuriating, as I get caught up in my work and forget that my Mac Mail is "moody."
I'm running Mavericks 10.9.4 and Mail 7.3.

I am on Mavericks 10.9.3 (brand new MB Air 13.3). I configured Mail with my IMAP accounts and it is able to send and receive mail. The problem is that the sound stops working after a while. When I sleep and wake the computer, at some point, it no longer makes the whoosh when sending a message. None of the other sounds work either. I have updated everything very recently.

This has been happening on and off for ages, from half a year to a year. I have been trying to open a document for 4 hours now, it opens it and then freezes, i then have to force quit it and start over again. Some times i have left it for a while others i quit it after it stops responding. It is getting ridiculous now, i have also searched for ages on the internet, some problems are unrelated some seem related but the fixes don't work, I need to get word to stop doing this.
I thought maybe it was because it keeps opening all my previous documents that I had open, i unchecked the box so it doesn't reopen windows and it still freezes but on this document instead. I do not have a clue what to do and I urgently need access to these documents, the documents aren't damaged, i was working on them before, and had this problem with many other documents that also weren't damaged. What should I do?

I have a 27" iMac purchased in July 2011. I never had any issues with the trackpad before upgrading to Mavericks. I upgraded a few months ago and started having sporadic issues with the trackpad. When the iMac woke up, everything seemed fine at first. About once or twice a week, after it had been working for about a minute (just enough time to start web browsing), the trackpad would suddenly stop responding. It then progressed to being more consistent (every other day). The cursor was still visible and the keyboard still worked. The trackpad was still on but apparently not connected. I thought it was the batteries, but new batteries didn't work. I could get the trackpad to work again by using Spotlight to open the Bluetooth System Preferences. The trackpad worked immediately when Bluetooth preferences were opened (nothing needed to be changed; it would just start working).
However, it would stop responding after about ten minutes. It was interesting because even if I left the Bluetooth System Preferences open, it would still stop responding after about ten minutes. I could use the keyboard to make the preferences window active and it would immediately work again. It would then work again for a few minutes and then stop. I found that removing the trackpad and re-connecting it would cause the trackpad to start working again more consistently. It would only stop if the iMac went back to sleep for an extended period (overnight).
The useful keyboard shortcuts are cmd + spacebar to open Spotlight, type bluetooth, use the arrow keys to go to Bluetooth system preferences (hit enter), use the arrow keys to go down to the trackpad, press spacebar to unconnect, again to confirm, and then after the trackpad is automatically rediscovered, press spacebar again to pair it.
This went on for about a month, when I had what I suspect was an unrelated problem. The trackpad started acting as if it was being held down (left click was always being pressed). I took it into the Apple Store and they confirmed it was broken. At that point I had a brand new trackpad.
The issue had gone back to happening every other week or so. I thought it might be interference, but I've since physically moved apartments and all the objects around it. It's been a couple months now and it's back to happening every couple of days or so. Since the trackpad is brand new, I have to think this is a software issue. I've noticed the following consistently:
1) It only stops responding if I've put it to sleep (I usually do so with a hot corner, but I don't have any reason to believe that's related) and haven't used the computer for more than 12 hours.
2) It'll always work right when it wakes up. It'll stop fairly consistently 1 - 2 minutes after waking up.
3) Time Machine seems to be busy doing something when the trackpad stops (the little icon is spinning in a circle if I have a Finder window open). Uncertain if it's always doing something or if it's coincidence that I've noticed it more recently.
4) As mentioned above, opening the Bluetooth System Preferences will always get the trackpad to respond, but then it'll stop after a few minutes. Unpairing and reestablishing the pairing will fix the issue for awhile (at the very least until the next time the iMac sleeps).
5) I may be imagining this, but before upgrading to Mavericks, I think it used to show the message that the trackpad was connected when the iMac woke up. I no longer see that message unless I remove the connection and setup the pairing again.
I've seen lots of people with various issues with Bluetooth connectivity and Mavericks. I'm on 10.9.4.

I received an Acomdata 2Tb external hard drive today from Amazon and plugged it in. Time Machine popped up and I declined to link the hard drive to it. I went into Disk Utility and chose the new hard drive on the left column and went to erase. I chose Mac OS Extended. I named it and hit erase. It started going, and going..... and going... and a half an hour later I knew something was wrong.
Disk Utility was not responding and I eventually had to Force Quit. Now I cannot format the hard drive. I starts and then it stops with a disk error. I tried to run the First Aid verify and repair and both stopped after a few seconds with an error. What do I do?

I have used Time Machine to backup my data on an external hard drive with ample space for the past year. However, for the past month or so when plug in my hard drive and try to back up my files using Time Machine, it completely freezes my computer, to the point where I need to hold down the power button for 10+ seconds and completely restart. At first I thought this might be due to not enough RAM, but discovered it does this even if all other programs are closed.

On a day-to-day basis I run: Adobe PS, INDD, and AI, Microsoft Entourage, Firefox and iTunes. Just recently, after an upgrade to Leopard, I added Things and Simplify Media to the list.The problem that happens before (on Tiger) and now (on Leopard) is command+tab switching stops functioning and Expose hot corners and shortcuts stop working.
I'm pretty sure this isn't a Finder crash because before, on Tiger, I could quit+restart Firefox and everything would be back to normal. Almost as if some shortcut had causes the system to act differently or there was some app dissonance?
But now, with Leopard, nothing I quit will cause these two features to act properly until I do a restart. Both features (command+tab switching and expose) are very necessary for my work flow. I have checked SysPref to make sure keyboard shortcuts are default and Univeral Access to make sure assisted devices is turned off.

Macbook Pro running on OSX Mavericks is having problems.
Today I turned my Mac on, and it started up with a loading wheel and a loading bar. When the loading bar finished, the Mac turned itself off. I tried many times, same happened every time. I then went into OSX Recovery, started repairing Macintosh HD, but the error message saying "Disk Utility can't repair Macintosh HD" came up and now I don't now what to do.
Is there any way I can back up my files in this situation? Is there any way I can repair the disk without having to erase all data and reinstalling OSX? Or do I really need to bring it to a Apple Store for repair?

I wanted to do a clean install and repartition my iMac running 10.8. It has 2 partitions. I booted from the recovery disk, went to Disk Utility and erased the two partitions. However, when I tried to change to a single partition got the error message "cannot unmount disk."

I have a MacBook Pro running Mavericks.
Recently I noticed that if I run Check Disk in Disk Utility, all the process works correctly but at the end it doesn't tell me that everything is correct (in green).
On the contrary, if I run it in recovery mode, (reboot w cmd-r), it works correctly to the end with the correct green result at the end.

I recently bought a new Kensington Slimtype keyboard for my PowerMac G4 (dual 867mhz); it's running Leopard and everything other than this is working beautifully. For some reason, whenever it goes to sleep, it turns the brightness down to it's lowest setting - not a huge problem, I just turn it back up. Just wondering if anyone else is having this problem and if they are, how did they rectify it?

I have a Mid09 13in MBP.
I noticed that when I put it in sleep, the USB ports still get power. Is there a way to make it so they turn off when it sleeps? I have a cooling plate attached so I have to unplug it every time I sleep it, gets pretty annoying when I forget and I unplug the USB plug and the MBP turns back on. My mouse/keyboard are BT so it wakes it that way, not by USB.
And is it bad for me to have the laptop running with the lid closed? I don't know if the heat would affect the screen or not. I'm currently not doing this because I'm not sure about the effects of the heat on the screen, but I do use a cooling plate, average temps are 120-130*F.

my eMac is somehow shutting down after going to sleep. I've checked the system preferences under energy saver and there are no schedules set for the machine to turn on or off. It does not happen immediately. It usually happens after a day or so. When I return to wake up the machine, it doesn't respond. I then have to start it from the start button. I don't get any error messages regarding the machine shutting down in the wrong way...just boots up normally.
I've had it for 5 years and this is the first time this is happening.
Has anyone experienced this before?
Can my machine be "infected" and controlled externally?

I have Leopard and this started yesterday. I put my computer to sleep. I then click my mouse. My mouse becomes active. Nothing else does. I tap the keyboard, press the power button etc. Nothing. To make it work again I have to force shutdown my computer by holding the power button. I cannot currently find my Leopard disk *sigh*.

With my Powerbook, whenever I shut the screen the computer goes to sleep. I was under the impression that (unlike the ibook) this is not supposed to happen? Is there a way to set the powerbook so that it only goes to sleep when i explicitly tell it to (i.e. the option in the Apple menu), so that for example when I shut the screen I can still have it hooked up to external speakers/TV/the network?

did a search under "sleep," couldn't find anything. If I don't touch my running iMac (OS 10.5.7) for five minutes or so, it reverts from a running state to some kind of sleep state--desktop replaced by screen saver, all running programs shut down, document I'm working on (using NeoOffice) closes. Computer is brand-new, system preferences/energy saver settings are: both sliders set at "never," no boxes checked, all are off. Damn thing is doing it on its own. Is there anything else I can reset, or is this a gitch?

If you use a external harddrive, I assume you have to turn it on 24hrs a day? And when the mac sleeps does it still back up on schedule? Can I use a internal drive i.e. bay 2 or 3 etc?
