ok so i suppose the inevitable had to happen. and so my mac OS X crashed badly within a few days of my getting this new MBP!
i had a short word document open in 1 workspace some firefox tabs in another, and was checking out the movies in my ext HDD (formatted with NTFS).and suddenly i start seeing this multi colored round icon which i guess is the cousin of the windows hourglass. after trying unsuccessfully to force quit, i was forced to hut down using the boot up button. yes, the same procedure that wreaks havoc on the HDD.
- so my questions are - what to do if even force quit doesn't work ? its surprising that it didn't in this case, as i have used ubuntu for almost 3 years and never had the OS crash on me! of course there were a few application crashes but the force quit always worked. and there was the keyboard shortcut - Ctrl+Alt+Del.
- also what is the norm with macs in this regard ? do they crash often and for the flimsiest of reasons as in my case ?
- probably i am not aware of the Mac OS equivalent for the Ctrl+Alt+Del function that almost always works in ubuntu. so is there some key combination that is guaranteed to work in the even that even force quit does not?
A few days ago I found that launchd was constantly using around 14% of my CPU (via iStat), which drastically lowered my battery life and caused my CPU to reach 75 degrees Celsius and higher. Initially I thought that SL just needed to do something, so I ignored it. But it has persisted for a few days now, so I decided to do something about it.
I checked the Console and nothing appeared to be repeating itself, so what I did was use MainMenu to perform a batch of system maintenance tasks, and then left my Mac on overnight to see what Console would report. Besides hourly instances of "kernel" running "iCalHelper" and "SubmitDiagInfo", there was nothing else.
However, launchd lowered its CPU usage to about 3%, but it is still constant and my CPU is still at a constant 40-50%. Activity Monitor says the following processes are (constantly) taking only 1-4% of the CPU:
coreservicesd
launchd
mds
WindowServer
disnoted
activitymonitord
...and others
The CPU is reported as 35% User and 20% System. But I am not running anything besides Activity Monitor.
Should I use my Apple Care, or is there a quick fix?

My iMac ( late 2012, 27", 3.4 GHz i7, 16 GB RAM, 3TB Fusion Drive, OS X 10.10.1 ) has taken to randomly restarting for no reason that I can find. It seems to be mostly when I am not actually doing anything, but, as I say, it's random. It did it five times in about half an hour the other day, then it didn't do it for a day or so, but it just did it again, which prompted me to ask. I have run Tech Tool Pro 7, and everything has passed. I have repaired permissions ( there were lots ). What next?

I have had my MacBook for 3 years and it has run great. Recently I have noticed that my exhaust fan has been hovering around 6000 RPM for no apparent reason. When I took that screen shot I only had Safari Open. Here's the vitals on my Mac..
View 1 Replies View RelatedI'm having a hell of a time with my mac. It started out when firefox would crash for no apparent reason, asking to send in an error report and eventually it got to where mac itself would crash, turning the screen dark with a picture in the middle appearing saying "You need to restart your computer. Hold the power button down for 2+ seconds". I've tried a lot, I've repaired permissions using the disk utility, I've reinstalled Java and I even verified the disk using the disk utility which seems to be the problem. It said my mac needed the system to be repaired. Except I've got a big problem: I just moved and I don't have the apple hardware test disc, so I'm stuck. Then, today I tried to use Safari instead of Firefox and even it is crashing. This is really irritating, I thought it was a virus until I downloaded a free antivirus that said it wasn't.

Now every time it gets to the apple logo I get the rotating "thinking" ident under the apple logo and it restarts, continually. I did the hardware test (holding down "D".....that was fine.) I also reset the PRAM... so the troubleshooting keystrokes work.
View 4 Replies View RelatedI have a Mac Mini with two external WD MyBook's attached. The drive in question, is configured for Time Machine backups every four hours. It should sleep the rest of the time. But every once in a while, it wakes. I just revs up for no reason, then after a short while it goes back to sleep. It can happen when I open a folder, open a file, click a link in the browser or some other seemingly unrelated action.
I tried to untick the "Put the hard disk(s) to sleep when possible" to see if I then at least could get the drive to stay awake instead. This did not change the behavior at all.
Does anybody have a clue what I can do, to get OS X to leave that drive the hell alone, other than Time Machine??
I have 750GB MacBook Pro and up until the other day I showed 250GB used and 500GB unused. I discovered this because the past two days my computer would just freeze and I couldn't do anything. So I ran the Disc Utility and it found some errors and fixed them. So I'm wondering if the 400GB of lost disc space now has something to do with the computer locking up? I've searched all the folders and added up their size and still come back to 250GB that I can see. So I'm assuming there's something hidden somewhere that's eating up over half my hard disc space?

When I boot into windows 7, on my iMac, the audio is muted by default. The audio works fine; no hiccups whatsoever, but it's just annoying to have it boot and be muted.
View 8 Replies View RelatedA few days ago I noticed that my mac mini was on mute so I tried the shortcut keys on my key board and they don't do anything so I go to system preferences > sound and it shows the mute check box checked and grayed out and above in the drop-down box where you are suppose to select what the audio sources is, is empty it used to say internal speakers, line in, and line out.
View 4 Replies View RelatedThis annoying bug is driving me crazy when I'm listening to music or watching a youtube video.It seems as if some process is interfering with sound output. I've already tried eliminating the problem by closing all apps, uninstalling perian, quicksilver, to no avail. Is there anyway to see which processes are using sound output at any given time?Â

Is there any reason to wait several months for the next OS update? I presently use Snow Leopard on all my machines, but using ICloud on my IOS devices is pushing me to a download of Lion. I just don't want to pay for it again in June or July.

Today I noticed a problem that has happened to many running 10.6.3. After a restart the sound volume goes to max and there is no sound from the internal speakers! In the sound pref it has changed from internal speakers to sound flower. What is causing this? No third party app that would need to install a driver are there like Avid media composer. I have tried restarts and smc resets no luck at all.

When the sound on my MacBook is muted, and there should be a sound playing (FOR EXAMPLE: EMPTY TRASH), the speakers click. It is almost like the sound wants to play, but does not, instead with a click. This happens every time.
EDIT: It also clicks before it plays a sound too. This happens only when the speakers are not used for a long time. Like a few hours.
Why does facetime mic cut out or go mute during calls?

I'm running OS X 10.6.8 on a 2.7 GHz i7 Macbook Pro with a 250Gb Apple SSD TS256C. Since last Autumn, after a problem that saw the SSD replaced by Apple and me needing to migrate my profile across from an older Macbook, every time the system shuts down it forgets my sound settings. So no matter how I set the sound before powering down it always chimes on start up. It's entirely possible that this may be a problem from the migration, but I don't know how to rectify the issue.

The volume is muted, but I can't un-mute it because I am unable to click on any of the sound options because they are all "grayed out". The little box next to mute is checked and I cannot un-check it because it's grayed out. Nothing works when I plug in headphones or speakers or anything, and there is no red light glowing where you plug the headphones or speakers in.

After removing the 512mb stick and installing the 2gb stick it worked fine, and then it started to crash without anything being done, so initially I borrowed a known to be working stick of the ram and put that in and the errors keep coming up? Even with the original stick it seems to be crashing for no apparent reason. Before I installed the new stick it was working fine the the 512mb stick, but she still does it with the original stick.

View 6 Replies View RelatedMy MacBookPro with Lion installed was stolen 2 months ago. I by accidant erased Lion from the 'installed' list in the app store. So i try to rebuy or reïnstall Lion on a MacBook with enough memory to run it, but in the appstore it keeps on saying 'you already bought Lion so this updat is free, push OK to download'.An update is useless without Lion itself on the laptop, but how can I reUinstall it via appstore? Or is there an other possibility?
