I have loved and cherished my MacBook Air for two years now, but last night it went in to a reboot cycle for no apparent reason. 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.

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?

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.

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.

I 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??
When I turn my computer on, a gray bar must be filled (takes about 20 mins) before it goes to the login page. Then, when I log in with the corrct password, the screen abruptly turns white like the startup white page for about 5-10 seconds (time varies each time) and then goes back to the login page where it will happen again and again. This all started when I banged my mouse and it stopped working and I held down the power button to turn off the computer and then hit it again to turn it on.

I got out the shower n pressed the pause button to stop the music. While that i notice couple of spot of water around my return button just a little. Nothing happened to the computer after using it for about 1 hours. So i left and came home around 7 hours later, got on the macbook air n then it kept prompting the shutdown menu option screen. From there it would just go to constant reboot. Is this due to water damage at all? or is it just a coincidence. Because my black macbook has had way more water on it before n its perfectly fine.

I picked up an 802.11n Airport Express card for my Mac Pro last week. The installation went fine, but my Netgear router was only 802.11g. So I felt the need to get an Airport Express now that it?s been updated to ?n?. First I plugged the AE into my switch along with my networked printer, cable modem, and Tivo. My 1st gen MacBook showed me full bars and was very happy. My Mac Pro only showed 2 bars. They are side-by-side and about 20 feet from the AE. Strange. I plugged the AE into an extension cord and moved it closer to the Mac Pro. Still, after the AE completes its POST, I get full bars on the Mac Pro. As soon as I hop on the internet, it drops to 2 bars. It?s really weak and pages take forever to load. Sometimes not at all. The MacBook is still fine.
My wife being used to PC nightmares at work suggested that I reboot. ?Heresy?, I said. ?I shouldn?t have to do that. It should ?just work?.? From the Mac Pro, I turned Airport off and then on again. Full bars again. As soon as I hop on the internet, it drops. So what?s up? Much to my lament, I rebooted. Bingo! It works. Full bars, all the time. So I moved the AE back to where I initially had it. (About 5 feet away next to the cable modem and switch. One less extension cord to deal with.) The AE completed its POST, gave me a green LED and I went back to the Mac Pro. 2 bars again! ERRRR!.............

View 3 Replies View RelatedThe title says it all. I have a new battery in my 2007 MacBook, but my computer still says it's at 237 cycles. Is there a way to reset the cycle count? It does say, however, the battery is at 100% health.
View 3 Replies View RelatedI have searched countless threads about battery health but I feel that each individuals battery health situation is so unique due to the numerous fluctuations.
I have a 2010 13" MBP with battery health of 92%. Load cycle: 13. and Age of 4 months( but i got it 2 months ago)
Should I be concerned with the battery health at this point?
I noticed that my battery cycle (according to istat) switches over at 15%. So as son as it switches over to the next cycle I plug in the adapter to make the battery run a cycle from 100%-0.(I know the cycle in 100%) But it still switches over at 15%, that means that the battery ran only 85% of its capacity. How can that be? Is it possible to reset (delete) battery cycle data?

Is it true that when we charged 100% battery and it says on AC power, does it LITERALLY do what it say? i mean the power of Macbook pro is not provided by battery but by magsafe instead. is it?last thing, leaving the Macbook connected to the working magsafe isn't add numbers up to cycle count right? and is it okay to charge the Macbook pro all the time and only using it when we could't find AC power outlet?

I bought a MacBook Pro 3 months ago, despite in the first charge I follow the instructions of the store. The problem is that my battery doesn´t complete the cycle of charge, if I disconnect my computer and the value of the battery decrease at 95% 96% 97% 98% or 99% and I plug again the charger to the MacBook Pro, the battery doesn´t charge at 100%. I followed all the instructions of synchronization but the battery remains the same.

So first off, I absolutely love my MBA. Now that we have that out of the way. Since day 1 I've noticed that the cycle count on the battery seems to be climbing MUCH faster than it should.
- I've had the machine 51 days. I was out of the country without it for 9 days so really, I've had it for 42 days.
- According to iStat and System Profiler my battery's cycle count is 37
- According to System Profiler my battery's health is "Good"
- According to iStat my battery's health is at 98% (It started around 96%, has been as low as 94% but seems to have settled in at 97 or 98% for some time now)
- According to system profiler my maximum charge is 5006 mAh. (It's also gone up a bit since the machine was new).
I thought the definition of a cycle was the equivalent of 100% depletion of the battery -- whether that's one long unplugged stint that sucks it dry or 10 really short ones. A cycle is the same as using ~5000 mAh of battery power. I've been really good about keeping it plugged in while I work (the outlet is conveniently located). I've run the battery most the way down maybe 5 times. I do, however, run it down 10 or 20% almost every day as the machine travels with me in sleep mode or spends the night unplugged in sleep mode at my girlfriend's place).
I haven't done any careful testing but it seems though that if I run the battery down just 20% or 30% or so and then charge it all the way back up the cycle count increases by 1. Considering I've only used it for 42 days, and the cycle count is already at 37, I'm worried that it will hit 200 cycles by the time it's 8 or 10 months old. Isn't the point where battery performance starts to wane? Anyone else out there notice a rapidly climbing cycle count?
I had some issues with battery drain while sleeping awhile ago but that problem has been solved. However, ever since that incident I could not be paranoid about the battery life etc.I heard people saying that leaving the charger plugged in is simply fine as long as I do the regular calibration once or twice a month or so. Yet, Apple stated that they do not recommend the laptops to be plugged in. I will be going to a college this Sept and I really do want my laptop to last at least the whole 4 years.
Ever since I have contacted Apple customer service about this Battery issue I have left my Macbook charged up and plugged in while using and letting it sleep. One thing I have noticed is that the battery indicator says 99% and doesn't increase or decrease yet the green light is on. Is that normal? Since this is my first Mac ever and also first Laptop I would like some advice on how to treat the Battery( I know how to do Calibration and such). Is it better to do full cycle usage of Alum Macbook battery than leaving it plugged in all the time? (I unplug it when the Macbook is off).
i have an older C2D MBP on its second battery. I don't normally use it on battery power so my cycle count is pretty low. I have attached images. It is telling me to service my battery. Should i be getting a new one? if so, how are the NuPower batteries @ OWC?
