My 2011 macbook pro started shutting off with increasing frequency. It was very frustrating. I installed mavericks and now it seems to shut off about every 5 minutes! Only if I'm working, if it's streaming it seems fine. I think it would be impossible to actually get work done. I've read many others are having the same problem and taking theirs in for costly ineffective repairs.
View 1 RepliesIs there any way to tell when the new processors are in turbo mode and shutting a core down and increasing clock frequency?Would be cool if there was a way to force this and see performance differences...

I looked into my issue a little but recently my IMac G5 started randomly shutting down when left unused for a bit but that seems to have stopped as far as I have noted. Now occasionally when it goes into sleep mode it will freeze on the black screen and the fan will go crazy. I plan on buying a MBP, if the update ever comes out, and then ill just completely wipe the IMac and give it to my parents, who still use the original I mac, G3 or something. I read a certain series of I Macs were having motherboard problems, W950 or something, but mine wasn't that serial code.
View 2 Replies View RelatedI searched the archives and I can't believe no one has mentioned this yet! This is a huge problem on both my Rev A and my new Rev B. When you connect an external monitor and external speakers using the headphone output, there is a high frequency ringing sound coming out of the speakers. I've managed to live with it by turning the treble to minimum and keeping the volume low enough but at the expense of sound quality. The strange part is, if you disconnect the monitor, the ringing sound stops. The problem only occurs if you have speakers and monitor plugged in at the same time. I've tried this on my Samsung monitor, my SONY TV, and my Panasonic audio receiver. The problem occurs with both Rev A and Rev B while my white MacBook and 2007 MacBook Pro all sound fine.

I've been using airport express for a year, but lately the airport utility ceased recognising my airport express. No matter what I did, nothing changed.I took it to my friends house, to try it on his mac, and the utility found it and the strangest thing was that my macbook (at my friends house) also found the airport express in the airport utility menu. But when I took it back to my place same thing happened, the utility could not find the wireless device. What could be the causing this? I mean, it worked at my place before and now it doesn't, but it works at my friends house. Could there be something that interferes with the apple airport express frequency?

I hope I'm not double posting. Have any of the other new iMac owners experienced weird frequencies coming from external speakers that are connected to their iMacs?
For example: I have a set of studio monitors that are hooked up to my iMac using a firewire audio interface. Whenever I'm copying data I get an extremely high-pitched frequency coming from my speakers that sounds like my hard drive spinning. Also, whenever I'm scrolling or moving the magic mouse I get a loud buzzing coming from the speakers (especially when scrolling). None of this stuff happened with my previous 20" iMac C2D. I have experienced this issue with all three of the 27" iMacs that I have gone through thus far (due to the yellow tint issue). Does this sound like something I'm just going to have to live with. All of these high pitched frequencies are driving me batty!

I recently upped the RAM memory in my 2008 vintage MacBook Pro to 8GB. I have not seen a significant increase in speed and it rarely uses more than 3GB of memory. In fact in some instances it seems slower. How can I boost the performance and take advantage of using the increased RAM?

I am considering buying a Macbook Air (June 2012 13" with i7-3667U CPU and the 4000 HD on-chip GPU) as it fits most my requirements. I occasionally like to play games and it seems that this graphics processor should be enough, but the question is how much memory can it use from the main memory and if the maximum amount can be changed. Â
More specifially I am loking at the requirements of ANNO 2070Â (as this is the kind of game I really like) and even though it has been known to perform ok with that GPU, the minimum requirements would be 512MB of video ram (on low or medium settings). The previous MBA was only able to use ~350MB of the main memory if I understand correctly.
1. What is the limit of memory the GPU can use form the main memory?Â
2. Is it user configurable under OSX?Â
3. Is it user configurable under Windows when bootcamping?Â
4. Is it "somehow" (unsupported software-only method) configurable?Â
5. Is the game ANNO 2070 playable under Windows (AFAIK using bootcamp is the only way to play it currently) on a new (June 2012) MBA?Â

I know the issue of the MacBook speaker volume have been discussed elsewhere, but I was wondering if there are any system hacks/applications that can increase the maximum volume?
I don't really use the internal speakers for anything other than system sounds and listening to web-content -- flash videos, youtube, etc. (In other words, if I want to listen to iTunes or a DVD, I'll use headphones or eternal speakers).
The max volume is just *barely* loud enough unless there is absolutely no ambient sound in the room...

increasing the amount of RAM in a MacBook Pro (latest model unibody 15" i7 processor). If I increase the amount of RAM in this laptop from 4Gb to16 Gb, should that in and of itself result in a decrease in battery performance? This is assuming no increase in number of active programs, etc. A friend of mine was told by an Apple employee that just increasing the total RAM in a laptop would result in the battery draining more quickly. I am no computer genius, but that does not sound right to me? After all, why should the battery work harder if the excess RAM is not being used at the time.Â

Recently I found my mba 13 to have start up times of 25 secs but more troubling is the fact that my shutdown time has gone up. How do I increase this speed? Also has anyone had problems where the MBA has hiccups every now and then?
View 3 Replies View RelatedSo 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 have a Macbook Pro 2.2 Santa Rosa Rev. D model. Recently I have discovered gray dots appearing along the top of my screen.
A few at first, but masses growing are growing rapidly. In the past 3 weeks the problem has started to spread to both my right and left edges as well. Under different viewing angles the dots sort of dissapear. The dots are not uniform in size or pattern.
I have a slight feeling that this has to do with my NVIDIA 8600GT graphic card.
I read tonight that that specific card was reported faulty and thousands have had problems and have had to get their logic boards replaced.
I also read that Apple extended their warranty for this specific reason.
Anyways, the dots are increasing and it's worrying me as I am not sure if this will be covered or not.
Machine Details:Macbook Pro 13inch model (2011)/Core i5 4gb RAM 250gb Standard harddriveÂ
The laptop was running like a dream and much better than I remembered my last mac (Macintosh LC) ever did. Ive had minor hickups this last year (a trackpad that went bust under warranty and a broken power supply) otherwise its been a wonderfull experience. The final hiccup that might be a cause, not sure hence I will mention it is that my battery is Conditon: Replace Now for about a month now. Â
The laptop, as always was left ON, on its own connected to the wifi home network, when I returned the computer was working very slow. Any load on the harddrive/CPU. The cursor starts lagging (jumping), any keypresses are registered with a 2-10second delay. Any vidoes that i would try to play would suffer freezes in framerates/jams but audio remained fine. First step i was afraid that i may have contracted one of the new trojans so i downloaded an antivirus program, scanned the drive, but came out clean. Second step was to format the drive and perform a fresh install of OSX but no luck. Being inexperienced in Apple products i assumed that my harddrive (used to PCs) was on the fritz and went out and bought a 160gb Western Digital Black series 2.5inch harddrive.
I placed in my installation OS 10.6 CD formatted the drive through the disk utility and performed a fresh install. Before doing any steps I went through the update cycle a couple of times till only the thunderbolt update remained (havent updated as I never used it). Sadly it hasnt solved the problems with cursor repsonse lag, video playback, and keyboard input lag under load. On this install I have performed:
Verify Disk Permissions Many were found so I performed Repair Disk Permissions
Verify Disk Came up with "Appears to be OK"
performed a Pram reset (CMD+option +P +R)Â

I have a Macbook Air and the new 13" macbook pro. I see that the Macbook Air is much brighter than the 13" macbook pro (under the same ambient lighting, both set to maximum brightness). I was told the reason for this difference is because of the lack of the glass layer on the Air. Is that really true ? If so, can you please let me know if I'd be able to get the same brightness I get on the Air on the Pro also by just removing the glass layer on my 13" macbook pro. TechRestore offers such a service for $134, which is simply a subset of their service for matte replacement (I don't want the matte replacement as I like the glossy screen). But since such a service would void my warranty and return policy, I want to be really sure before getting it done with them. I'd greatly appreciate any inputs/advice.

Like many of you, my magsafe finally started getting hot enough to make popcorn. Where I would have gone out and bought another, a simple dead short was too easy of a repair.... and I can use that $80 for other Apple goodies. I might as well get something out of my electronics degree. I decided to take pics to share. Since I seem to take pics of things people like these days, I've watermarked them to avoid any *more* theft of images. Apologies in advance for the watermarks. I would have written this as a DIY, but I determined if you couldn't get the jist from the pics, you shouldn't be attempting it. (Self solving problem) Basically what happens is that the outer shielding breaks FIRST from the flexxing of the cable. Once the outer shielding breaks the wire loses all it's structural integrity and it's a very short time before the inner wire starts poking through and creating small dead shorts between the + and - voltage of the two. This is why some days it is blisteringly hot and some days it is not. There are only small strands of the inner wire poking through and each time they make contact they burn off, creating a very hot wire, but one that seems to fix itself or only randomly get hot. If you continue to use the adapter in this situation you WILL end up with a fire that can threaten your book, your home, and your life.
At this point in the life of the wire it is in critical. The inner wire is breaching the jacket and the outer wire has nearly broken in half. The effects are a very poor connection on the negative shielding which creates heat by lack of ability to properly transfer energy. The heat warms up the already damaged inner jacket and the next thing you know.... you are here complaining about your Magsafe almost burning your leg off. With a little skill, you can fix this issue and save $80. The process took me 45 minutes and cost me NOTHING. My adapter is like new and will last me another year before I have to do it again. Inevitably by design, all Magsafe's will fail. I don't know about you, but I have better things to do with my $80, so once a year I don't mind making this repair. If you buy a new Magsafe it WILL fail again. The revision of a SLIGHTLY larger rubber grommet is a horrible fix with minimal results.
I was using my Macbook as usual last night, when some of the programs froze and the laptop started to get extremely hot. I tried to quit out of them but they were unresponsive, and unsure of what to do about it closed the lid and let it sleep and cool off. This morning I have tried to close the programs again with no success, so I hit the power button to restart the laptop. Now it doesn't boot, a folder appears on a gray background with a question mark in it. It wont boot to windows either, just sits on a gray screen. Can anyone help? What do I do? I'm not brilliant with computers, but I don't think I had done anything to crash the laptop. I had upgraded to Snow Leopard earlier on though, and not had any issues until then.
