MacBook Pro :: CPU Heats More After SSD Upgrade

Jun 25, 2014

Is it normal that the back temperature of my MacBook Pro 2011 is higher after upgraded from HDD to SSD?

I guess this is due to the fact CPU is not limited anymore by the HDD..

MacBook Pro :: Heats Up When Flashplayer Is Running?

Feb 26, 2012

I am just wondering whether it would be possible to reduce the heat rise that occurs once flashplayer is running. Everything goes back to normal when the player is stopped down.

MacBook Pro :: Heats Up While Playing Games?

Mar 31, 2012

I know the heating up issue has been raised several times all over the internet. But none of the discussions  has satisfied my the concerns I have with my system. So I am going to put my case a new, although I believe the answers are going to be the same as on other similar discussions. 

I recently bought MacBook Pro (15 inch, 2.2 GHz, late 2011, OS X Lion). The system usually runs perfectly. I just have two issues: 

i. Occassionally it freezes up when more then one apps are running. I have noticed this is usually when Firefox is running in the background. Also happened with Safari a couple of times.  

But my main concern and query is the point no. ii (below)  

ii. During the normal usuage the fans don't make a noise (even with multiple apps that are not burden on the RAM). The systems heat up is as normal as that of a PC while running on its normal situation. However, when I play games (like BioShock, Sims etc) Mac just heats up immensly and fans kick in. I have never seen/felt a computer get this hot before.

MacBook Pro :: System Over Heats When Asleep

Jun 24, 2014

My late 2012 MacBook Pro overheats when asleep. The fan blasts until it shuts itself down (I get a message). This started after the most recent update. I am at 10.9.3. Also, I now have a magenta flash when starting up. Now I always shut down the computer when I am done so it won't destroy itself.

MacBook Pro :: MBP Unibody Heats Up With Apple Cinema Display?

Jul 18, 2009

I bought Apple Cinema Display and a MBP Unibody. I was told that the lid of the MBP must be closed from boot-up so that the display will be transferred to ACD. I did this, I found out that after a while, even with no high cpu load or usage... it become very hot and fan goes up.

The heat goes away when I open the lid... I tried putting a cooler fan below the MBP.

MacBook Pro :: GPU Over Heats When Viewing Videos On Safari... How To Make It Cool

May 8, 2010

Not sure if anyone else has this problem or not, I noticed on my 2007 model MacBook Pro, that when I view videos through either Safari, Firefox or any other browser, my GPU temp goes up to around 81 degree celsius unless fans kick in OR I set them to kick in.

I observe temp using iStat Widget.

On the other hand, I just finished watching a movie on my very same laptop through VLC, that is through a media player and not through flash and noticed that temperature barely hit 63 degree celsius. I know flash still has issues and that this will not probably improve with my model ever in the future, but is it normal and should I live with it?

MacBook Pro :: Heats Up Immensely Every Time It Wakes Up From Sleep Mode?

Jun 13, 2012

I own a early 2011 edition of MBP, with 2.3 Ghz i5 processor and 4 GB ram. Everytime it wakes up from the sleep mode, it heats up with the internal fans constantly on.. Moreover, the estimated battery life shows as 2 hours even when the percentage is 97%.. However, when I restart the MBP, the heating stops and the battery life shows 5 hours..

MacBook :: Is It Too Heavy Than Air

Jun 11, 2012

Comparing the updated MacBook air and pro 13 inch, for the high end version of both models, which laptop comes out better for performance? Add the 8GB of Memory instead of 4GB and potentially the 2.0GHz i7 upgrade to the air and does it bring it up to higher level than the pro? Primary use is for study needs (so portability is important) as well as music, videos, and games such as the GTA's, sports games and games like Civ V. Is the pro too heavy? Is the air to structurally flimsy?

OS X :: CPU Heats Up Then No App Will Run

MacBook Pro :: BT Dropouts Under Heavy Wifi Access?

Jul 24, 2009

Just bought a 23" dell monitor and BT keyboard (already have wireless Logitech mouse) to use with my late 2008 MBP.

Almost immediately I noticed I was getting frequent 'Connection to Keyboard lost' errors, almost 100% of the time this happens the Wifi is under heavy use moving large files to my NAS for example.

I searched Apple support and this appears to be quite common and 1 suggestion was to change my airport extreme base station to use 5GHz instead of 2.4GHz for the network. This tweak seems to have solve the issue 100%, the only downside is not all of my kit can use 5GHz .. for my work laptop I've invested in a new wifi adapter that'll cope but my Apple TV and iPhone can no longer connect to the WLAN.

Anyone else have an alternative solution for this? Or is it pure and simple down to BT interference and I should perhaps ditch the BT keyboard for a wired one?

MacBook Pro :: Heavy, Continuous System Lag, Kernel_task @ 100%+?

May 27, 2012

i was playing Diablo3 when i suddenly experienced heavy, unusual lag. I tried to reboot to see if that could even things out. No success. It took longer then usual to boot up, and when i finally reached the login-windows asking for password, it wouldent react to my typing and clicking for about 5 minutes. I could move around the mouse and the keyboard did get signal (it un-dimmed the scren when i pushed any key after letting it dim over time). 

Then i tried to do a clean install of OS X Snow Leopard (formating the drive and then install). After longer then usual,reached the "choose your language" window. This window too had extreem long respond-time. I managed to start the installation but it stopped at 33minutes remaining, giving me the "Install Failed" window. this told me "Mac OS X could not be installed on your computer. The installer could not copy the necessary support fies. Click restart to restart your computer and try again.". I tried it again but it gave me the same result. 

it made me believe the hardware was the problem. First i swapped the Optical Drive with an older vrsion MacBook (2008), this gave me the same install-problem (stopped at 33mins left) Then i swapped HDD with the older MacBook. It managed to boot and start "normally" with exactly the same problems as the original HDD. The first thing that gets to my mind is that something might be fried inside the computer. 

I restored the original HDD with TimeMachine (needless to say i still got the problem). I'm in the middle of my exam-papers, so its reaelly annoying its happening now.I also tried installing OS X SL using an external HDD with an image of the installer disk made in disk utilities, but this only gives me "kernel error" during booting (the annoying dimmed screen with a black box in the middle telling you to restart). 

Today i took a look in the Activity Monitor and it shows the CPU acting strange, spending 100-120% on kernel_task ALL the time (see added picture).Is something wrong with the CPU? Is it possible to fry only one core in a CPU leaving the others intact?I have different components available for change as long as they match each other (Macbook pro 2010 and MacBook 2008).

When it happens the laptop is unresponsive and the coloured mouse wheel appears for about 20-40 seconds and then it will work. It is extremely agrivating. I have thought about reinstalling but surely there is a simple reason

MacBook Pro :: Notebook For Performing Business / Home Tasks

Aug 16, 2010

I'm in the process of researching my next notebook purchase. If people could attempt to maintain an unbiased viewpoint that would be very useful. I'm a qualified accountant currently offering personal tax and finance advice. The form factor I've decided on is 15". I've considered the 13" but I can't justify giving up the screen real-estate (and the fact I'd go for the hi-res screen) for the added mobility. My everyday tasks are split between work and home use. As a general oversight these include multimedia, photo editing and extensive MS Word/Excel. Assuming I go Mac OS I will also require decent Virtualization performance on the occasion I need to run Windows software I use for my work. The packages cannot be found in Mac OS form.

The following factors are also important:
-Build Quality
-Battery Life
-Value for Money Hardware & Specification

From the first two points you can see why I am considering the 15" mid-range i5 MBP. But I am struggling to overcome the third point. For example a similar specfied Vaio E Series is approx. $1000 ($700) a-drift and includes a BDVD player. But bad experiences with windows notebooks have taught me that they are generally built to last 18-24 months at the very best. If I could find a machine with the build quality and battery life of a MBP with a windows OS I'd be more than happy. Don't get me wrong, I love Mac OS, however the financial industry in the UK seems to be significantly dominated by Windows software and I refuse to run two machines.

MacBook :: X Over Battery Icon And The Fan Is Running Even Though No Heavy Duty Performance?

May 20, 2012

Earlier today, maybe around 3PM, I was using my laptop, and it was charging and it was maybe around 60% battety life when out of no where it just shut off and even the light on my charger went out. When I turned it back on, the fan was running and there was an X over the battery icon. I've tried turning it off and on, and leaving it alone for a few hours, to see if it would resolve the problem but it didn't.  It is currently 9:52PM, I'm still experiencing these problems and I'm using the exact laptop to type this, but I don't know how much battery life is left.

MacBook Air :: Heavy Memory Loss Storage - When Saving PDF Document In Preview

Sep 1, 2014

I am currently editing lots of pdfs and other files for notes. There is one particular big file, ca. 300 MB (part of a book). When I edit this file in Preview (underlining etc.) and save my changes, I loose almost the whole size of the file in disk space.  

Saving 10 times, that equals ca. 3 GB. Since I am a diligent "back-upper", I loose ca. 3 GB every 90 minutes. Over the last 3 days, this has consumed more or less 40 GB of my storage space. I have restarted several times and had to delete a lot of files; the sleepimage file is ca. 1 GB big only, so that is not the problem;so I have used "Disk Utility" to localize the massive space use. 

Disk utility registers the storage loss in total numbers (35 GB free, next time only 32 GB free), but not within the folders (the single sizes of the folders -Application; Library; User etc-), their sizes stay the same!what happened to my disk space. I need to restore those 40 GB they are being used by something completely useless somewhere.

Memory - 16 GB 1600 MHz DDR3
Graphics - NVIDIA GeForce GT 650M 1024 MB

Problem - It happened couple of time, earlier it happened when I was opening "" (I know, it was Black Friday time ) and it happened yesterday again, while opening When the problem occurs, machine hangs and after some time I can move cursor, but can't do anything. I have to hard restart the machine. after machine restarts, it shows a popup saying that a graphics problem detected and do you want to report it.

I suggested switching off "graphics switching" from energy menu in system preferences. even that crashed the machine first time when I tried that. So I have graphics switching off for now. Don't know for sure if it is OSX bug, Chrome/Browser bug or something else.

MacBook Air :: Production - Handle Heavy Music Editing With Logic Pro - Lack Of External Port?

Mar 23, 2008

I do not own any Mac at home, but looking into one for college. I have read up on all the pros/ cons of the MBA (non-removable battery and RAM, lack of ports and optical drive, etc). I am not a computer gamer, so I stick to the consoles. I was wondering if a MBA is ideal for any kind of music production. Can it handle heavy music editing with GB or Logic Pro? Is it ideal with the somewhat "lack" of external ports? share your opinions and/ or experiences with music production for fun or work on a MBA. (By the way, I am asking this to decide whether I should be looking into a MBA or MBP for college September of 2009, so I have LOTS of time to wait for newer models).

Software :: HTML5 Assault On Adobe Flash Heats Up With ClickToFlash

Oct 6, 2009

As Adobe works to port its full Flash Player to mobile platforms and highlights its upcoming support in CS5 for building iPhone apps using Flash tools, an open source group is leading a drive to kill Flash on the desktop using a WebKit plugin named ClickToFlash. El asalto de HTML5 a Adobe Flash se calienta con ClickToFlash ClickToFlash allows Safari users to isolate Flash content on the web so that it only plays when they choose to allow it. Flash content is replaced with a bounding box that enables the user to ignore the item (such as with ads) or to click the placeholder to activate Flash playback as desired. Additionally, the plugin can convert requests for YouTube Flash videos into requests for higher quality H.264 videos, allowing desktop users to bypass Flash the same way the iPhone does, and simply play any YouTube videos using the browser's own built-in HTML5 support for direct H.264 playback.

The examples below compare the same HD clip served by YouTube, first rendered using Flash with the standard grey YouTube playback controls, and then presented in H.264 using ClickToFlash to request the non-Flash version from Google. The native HTML5 version results in Safari using its own native QuickTime X playback controls rather than those created by Google using Flash......

OS X :: How To Get Heavy Pixelation In AVI

Mar 7, 2009

Ever since the last QT update 7.6, my AVIs are so pixelated to the point where it's no use for me to edit them in FCP. They're more like thick white blocks that completely distort the image. I have both Perian and Flip4Mac up to date. I'm also using MPEG Streamclip to convert to a more friendly h.264 clip.

Mac Pro :: Freezes When Performing Certain Tasks?

May 27, 2012

My Mac pro has been freezing recently which requires me to hard boot and I'm not quite sure whats going on. Let me go a bit more into detail. Now when I say freeze, I don't mean beach balling, I mean literally the entire screen is motionless and I must hard reboot. Its odd really, the computer only freezing when doing certain tasks, such as when I render 3D graphics with Cinema4D, or whenever I play certain games on steam.I have recently installed windows as a partition for bootcamp, but I don't believe that is the issue. I have experienced the freezes while running my machine in both Windows and Mac. Its important to note that when booting my Mac in SAFEMODE, the freezing does not occur while performing the same tasks. So this leads me to believe there is a process going on thats causing the computer to freeze up? What I think I have managed to rule out as problems:

- Not a Hard Drive failing issue, I booted from my backup hard drive and the freezing still occurs.

- Not a Heat issue, I've installed iStat and my top temperature barely raises to 60 degrees celsius when freezing occurs.

- Not an issue with the Windows partition, as I booted from my backup drive that is without the partition and the freezes still occur.

- Not a Ram issue, I took my ram cards out and swapped them around. 

One other things... Not sure if this is relevant, but upon one of the freezes, I rebooted and got this on my startup screen, It was bizaar and it froze here as well. This only occured once but I snapped a photo of it.

OS X :: Windows So Slower At Most Everyday Tasks?

Dec 12, 2009

Most people here know that if you have two computers, both with the same hardware, and one is running Mac OS X and one is running Windows, the Mac is usually faster in most aspects. I know that Windows is, in general, a much less efficient OS, but specifically, why? I've heard that a lot of it is due to the fact that Windows will try to do 100 useless things if you ask it to do one simple thing, also I've heard that Microsoft wrote Windows by getting loads of people to go off and do different parts of the OS, then they would just paste it together rather than taking off the useless parts, fitting each part together and optimizing it. I just need a more straightforward answer as I will be using it in an essay.
