MacBook pro 1.86GHz Temperature Reading

I'm just curious on what you all think because to be honest after reading all the stories about temperature of the MacBook Pro I decided to get the kernel hack for reading the temperature sensor.
With the MagSafe plugged in, brightness turned to full and the Better Performance mode selected I used it for some general web browsing and Instant Messaging. Also did some basic video editing with video recorded on the iSight. Left all this running for about 10 minutes and took a temperature reading.
The reading came out as shown here:
60 Celsius or 140 Fahrenheit.
After leaving on same settings but idle and not doing anything I took another temperature read out and discovered it only dropped to 59 Celsius.
Are those temperatures within reason?
The area above the F keys are hot to touch and bordering on untoucheable. Likewise for the area on the underneat of the laptop.
Everywhere else on the chassis seems to be moderately warm.
What are all your thoughts on the above temperature read outs?

The heaviest load would have been video editing. Under such a load 60 C is reasonable. The subjective temperatures you felt on the metal strip behind the function keys and on the case bottom are typical.
59 C after an period of inactivity following video editing is a bit high but doesn't necessarily indicate a problem. But if you start with the computer at ambient room temperature, do nothing or only very light work and the CPU stabilizes at 59 C that's somewhat high unless your ambient temperature is rather high. Sleep your computer for a time until it cools down, then resume it and monitor the CPU temps while at idle or low load for a good while.
I use an aluminum tilt stand when my MBP is on my desk, or will be in my lap for an extended period of use.
Plugged in, my light-duty (writing and Web surfing) temperatures typically range from the mid 40s to low 50s C. My keyboard and trackpad are not warm and the left palm rest area is at or about body temperature. So the computer remains comfortable to use. The CPU temperatures for comparable activity drop by several degrees. When I'm doing web surfing I'm usually selecting material for download, which results in more activity than just web surfing alone.
Even when I'm doing heavier duty work that frequently pegs the CPUs my computer remains comfortable to use. So I don't have a heat problem.

Hello MacBook Pro Musicians- I cannot read sheet music from the ipad. It is too small. I want to connect a large monitor, hopefully wirelessly to my 13 inch macbook pro. what would I need to connect ? Any suggestions on how to keep monitor from falling?

Hello Macbook Pro Musicians--I cannot read sheet music from my 13" macbook or from an IPad. The print is too small for these aging eyes! So I need to get a large monitor to attach to the Macbook. I want the monitor to be connected wirelessly or using a blue tooth. This will eliminate alot of potential mishaps
when playing out. Also I am having a time figuring out how I am going to safely keep the monitor on somekind of music stand without falling!!! Can anyone help me with this?

Hi Julius,
As you can see in my profile section, my MBP is older by 5 years, 2GB RAM and with regards to question 1 (Q1), has no problems with having all those programs open at the same time with the possible exception of Photoshop since I use Gimp instead. With twice the RAM and much overall much better specs, Photoshop shouldn't be an issue. But you listed some other activities that might need that additional RAM. But the advise most give is to not get it from Apple but from a third party.
Q5 - I always get Apple Care. Only had to use it once but it paid for itself that one time.
Sorry, can't help you much with the questions you really want answered since I won't have a new MBP until (hopefully) next week but for Q4, I believe it depends on the peripheral. My current monitors are too old to allow them to be hooked up in a chain. Supposedly, if the monitors do have the ports, you could via the MBP Thunderbolt port. The speeds are also dependent upon the peripheral. If the external hard drive is using a USB 2 port, you are limited by that speed (480 Mb/s). If it has a Thunderbolt port, then from what I understand, we, my friend, are in for some great times because I believe your RAM will have the ability to access data as fast as it can take it at 10Gb/s (and if will need those kinds of speeds, the 8GB of RAM may be the way to go). The Thunderbolt demos on YouTube where they are accessing four video files from a Raid drive, then sending them back out via Final Cut Pro to a monitor are amazing. I'll probably never push this machine to anywhere near it's limits but I can't wait to see what others do.
Peace,
Jeremiah

My Macbook Pro suddenly won't read my hard drive.

My Macbook Pro suddenly won't read my 750GB WD Elements Hard drive.
It was working earlier today but when I went to press play on my TV show in VLC it said the files couldn't be read. So i reopended them all and they still didn't work. I closed down all programs running that could possibly be using my hard drive but it said it was being used so I force ejected it and when I plugged it back in it didn't work.
It comes up with an error message "this disk can't be read by this computer" but it still shows up in disk utility. In disk utility though it says it is a 2.2TB hard drive which confuses me. also I the buttons for "verify disk" and "repair disk" are greyed out.
Is there something that I can do to try and get my hard drive working again?

If I'm not mistaken, this drive is bus-powered. MBPs seem to have frequent problems with bus-powered drives, probably because they don't provide enough power on the USB bus.
In disk utility though it says it is a 2.2TB hard drive
It is possible that the drive or USB interface are damaged. However, it is too early to decide. You need to connect the drive to a desktop machine (Mac or PC), or provide more power to the drive (with a power supply, if the drive accepts it, or a USB Y-cable and a USB power supply, rated 1A or more).

HT1338 My macbook pro(2010) is not reading the hard drive, but the hard drive works through the USB?

Hi everyone,
My Macbook pro(2010) is not reading the internal Hard Drive. At first I thought it to be a hard drive gone bad, so i bought a new hard drive. My macbook is still not reading the Hard Drive. I am able to use the original hard drive through a external(USB) connection. Also, when the macbook turns, there is a redelling sound. Can anyone offer me any suggestions to what the problem might be?

It sounds like the internal cable connecting the HDD to the logic board is improperly connected or faulty. An appointment at an Apple genius bar might be a good option. The repair should not be too expensive.
Ciao.

How do I burn imovie to dvd on my macbook pro that can be read by dvd player to watch on my TV.

How do I burn imovie to dvd on my macbook pro that can be read by dvd player to watch on my TV.

Purchase iLife 11 (includes iDVD) on disk.
IDVD is a wonderful piece of software and well worth the low cost of $40.

Yes, there are programs that will put a movie on a DVD. I have tried most of the other substitutes including Toast, Burn, DVD Creator, Wondershare, and others. None of them come anywhere near the ease-of-use and power of iDVD. IDVD is specifically designed to work with iMovie.

MacBook Pro Retina 15" Temperature

Hi there,
I'm currently using Windows 7 on my MacBook Pro, and using CPUID Hardware Monitor (which I can only assume is accurate) I've noticed the temperatutre of my cores sits at 55 - 65 degrees celsius when idle, but after less than a minute of running GTA IV through Steam (as a test) the hottest core gets to a whopping 105 degrees celsiuis (the others are at 103 or 104). And yes, the fans are engaging at full bore pretty quickly, and then I notice the cores start to run at 75 - 80 degrees celsius which seems much more reasonable.
The Mac itself is about six months old, and I understand from reading through other topics that the heat tolerance of these Macs is somewhat higher than that of a regular laptop, however I just wanted to ensure that this was normal because I can't really find much information on their temperature tendencies (albeit through my brief google search).
Thanks.

It is normal. What is not normal is running games that use the CPU and GPU to such an extent that the temps near critical shutdown. Modern laptops are really not game machines. They are built for small size, minimum weight, and little interior space. This means that cooling capabilities are limited.
If you want to play those types of games, then use a desktop computer with a good cooling system.

Macbook Pro 13" 2012: Temperature?

Hey guys,
So I recently purchased my 2012 Macbook Pro 13" and am loving it. The specs run:
- 2.9ghz
- 8 gb ram
- 750 HDD
- Intel Graphics 4000
My only problem is that when I play World of Warcraft/Diablo 3 the computer heats up pretty quick. During play it hits about 94C and the fans are running at about 5700rpm. I was on the phone with an Apple specialist and he said he plays WoW on his MBP and it tends to get pretty hot. But, I wanted to get some feedback from the community. Is this temperature dangerous to my computer or is it regular when running games and am I just acting stupid?
P.S: I'm not worried about graphics. I ran WoW fine with my intel graphics 3000, 2.7ghz i7, 256SSD computer.
Thanks,
Nick

macs run hot (especially when playing games or watching videos) as the Apple rep said. Your mac will shut down in the event it gets so hot to the point where it may cause damage.

Macbook Pro Retina Hight temperature

Hi Guys,
A few months ago I bought a Macbook Pro from you with 16GB of Retina
256GB SSD and HD.
I installed on my MACBOOK PRO software ISTAT which measures the temperature of
I was really scared and even as much as it heats. Already
I reached the mark of 92 degrees celcius here. Almost temperature a water to boil. He even miss the keyboard at times that
I was typing.
I downloaded and installed the system and smcFanControl improved somewhat, but
the temperature gets too easy at 80 or 85 degrees.
Have you googled including ventilated bases for notebooks to see if it improves
this situation.
Sometimes even here in my office where I have air conditioning temperature
reaches 79 degrees easily.
I have worked with the screen brightness below half, because I noticed that
also influences the temperature increase.
If'll see some video on the web, the temperature goes up there.
Anyway, I paid this notebook and dear of you who want instructions
are the experts to solve my problem.
I use a macbook pro for work and am actually a little worried
and finding that the product will not last long.
I also wonder what is the maximum that this coolers my macbook
withstand a run on rpm?
What is the average temperature in that he was made to work?
What software should I use to increase the fan speed. I came
also to read about and noticed that has software where one of the users who
bought not recommended because of it ruining their coolers by
having rotated at a very high speed.
I wonder if this is some bug in the operating system, whether it is a failure
project, finally, I want you to get a solution to my problem.
So I wait for you as I do I do to solve this my
problem.

It's on the Sensors menu of iStat...... since posting that I've seen the cpu tempreture get up to 90 but the fans don't seem to automatically speed up, I ended up manually putting them to maximum which cooled it right down very quickly

2012 Macbook Pro Retina High Temperatures

I recently started noticing my 2012 Macbook Pro Retina was feeling warm to the touch on my legs. I installed temperature gauge and was startled by the temperatures I saw.
Idling the CPU is around 40-45 C but spikes easily to 70-80 with any activity. As an example when Intellij compiles my java code my CPU will jump to 80C
The SSD temperatures is constantly at 65C.
I tried reseting the NVRAM with the instructions from Apple website. It didn't make any differences.
What is even more concerning is the fan speed does not change! It stays right around 2000 RPM no matter what the temperature is.
Has anyone else had similar experiences with their 2012 Retina? I recently had it at the Apple Store for repair to replace my screen, ghosting issues.

Hi there,
You may find the information in the article below helpful.
Mac notebooks: Operating temperature
Mac notebooks comply with temperature limits set in national and international safety standards when used in accordance with the instructions in the user guide.
While there are third-party utilities that measure the temperature of a notebook computer, it is important to understand that these utilities are not measuring the external case temperature. The actual case temperature is much lower. Never use third-party applications to diagnose possible hardware issues—instead, contact Apple or go to an Apple Retail Store or Apple Authorized Service Provider.

Macbook pro w/ retina Temperature normal or not?

I got a brand new Macbook pro with retina about 4 days ago with the following specs: 13 inch 16GB ram i7 (the best upgraded 13 inch laptop). I noticed that the top right of my keyboard (above the power button) is getting slightly warm. The temperature using temperature gauge displays 45 degrees (for CPU) when the laptop is just turned on. The only app I downloaded so far is Skype, which is not even logged in.
The temperature goes up to 50-55 while browsing the internet (Safari). Right now (while I'm writing this), it is 48 degrees with 1289 RPM.
I wouldn't say the laptop is hot... I would say it is warm. However, when playing some games, it does go up to 65 to 70 (sometimes even 75), and the surface does get hot. The laptop is on a table, I don't use it on my bed or pillow or anything.
Could someone who have the same laptop maybe download the app and check what their temperatures are like? And whether or not this is a big issue.
Thank you

I'd strongly recommend to go with the refurb model because of the dedicated graphics card. You are saving $40, getting dedicated graphics card, and a 0.4 ghz boost.
Now the 0.4 ghz isn't necessarily the biggest factor here, but the GT 650m sure is.

My MacBook Pro can no longer read/play/do anything with DVDs. I tried re-installing OS and Leopard but discs are rejected almost as soon as I put them in. For some reason my computer is rejecting any and all DVDs.

A few weeks ago I noticed my MacBook Pro was unable to open or read, etc... DVDs. This included DVDs with jpeg photos on them and DVD videos. I thought I might have deleted something necessary to DVD use. So I tried to re-install OS software. This included Snow Leopard and the original two Mac OS X discs. None would open or play or install. All were spit out of computer soon after I stuck them in.
So now what can I do? Thank you.

Do you recommend the canned air
It works just as well as the regular cleaning discs works. The only disadvantage is that you will need to keep purchasing canned air once it runs out. Cleaning discs last forever or until the tiny bristles on the disc wears out. Whichever comes first.
Any store that sells cds & dvds will also sell disc cleaners. Prices vary but they all do the same thing - clean your slot drive.

My MacBook Pro SAD experience: MUST READ if you are about to get 1.

Things to clarify at the beginning:
1. im not an english native speaker so try not be too picky for my language.
2. im not a mac hater and i've own a powerbook 17 1.5g as well as a iMac G5
Here we go:
1. I've spent £2000+ to get my top spec MacBook Pro (2.16/2G/7200rpm) so i'm kinda expecting for a super computer, am i wrong?
2. My first unit failed me on the 4th day of purchase, after I spend 2 entire days to load all the software up, immigrate all my emails and academic papers from my SONY FE11s, it failed. The system won't start up and i can't even see the Apple logo after press the power button. I bring it to Regent Street Apple Store, and the genius told me that it is because my DVD is stucked inside and the MacBook pro iS KEEP READING it instead of the Hard drive.
Then we tried holding C, Mouse Button, F12, Eject, reset PRAM, PMU and the disc just woudn't came out (a standard dvd). Then they said they'll crack the machine open to get the disc out and they'll give me a brand new replacement right away. ( You can see how stupid is MacBook Pro's firmware designed, even it IS the disc's faul, it should be able to skip reading it after say 30 seconds or so and go straight on to the harddisc right? )
The genius said that they will give me a call once they managed to get the thing booted and transfer the original data to my new MBP. The next day i get a call, saying that all the HARDDISC DATA was "destoried" and "Unrecoverable"... and I've default my FE11S sony and put it on eBay. so i don't manage to keep a copy of my files.
3. Heat issue.
No matter what people tell you, don't believe it. go to any apple store in the afternoon or evening while their display machines have been running for several hours. touch the bottom of the screen and the body. It burns your finger. Now i'm using my macbook pro on iCurve (which hangs the mbp in the middle of the air and make a perfect cooling condition) and the room temp is around 15c. The machine is still EXTERMELY HOT even i just use it to browse web for 30 minutes. I did not dare to touch the bottom of the screen (where the MacBook Pro words are displayed), and it will be a GREAT PAIN if you insist to touch that thing for over 2 seconds and want to DEMONOSTRATE it is safe.
4. Stability
Yes i know we Mac users always teasing around with Windows Bluescreens, but the macbook pro i've got in hand hangs every one or two days AND without famous "four langauge error message". It just hangs there like a overclocked PC! i'll have to hold the powerbutton and get it shut.
5. Memory consumption
Rosetta is one of the biggest fat lie that apple have made. without 2 gig ram don't dream to use over 2 ppc programmes at the same time.. just let me show you something ( yes i was watching a live tv show in safari hence the cpu and memory consumption, but that is still far more than i will expect ) 22mb LEFT with ONE PPC programme on ... I only notice this because i was trying to mount a disc image and failed with error msg "too many applications running"? is it too many for a £2000+ coreduo and 2g ram laptop? take a look at the screen shot and judge it yourself.
With the great pile of "INACTIVE MEMORY", i really start to doubt the ability that mac os x tiger handels the memories. After the screen shot i've shut down all the running applications, then i switched the activity monitor back on, guess what, i only get less than 200 mb free memory, the rest are still inactive or locked up....
CONCLUSION:
Yes the macbook pro is superbly fast, espcially after i got my aperture 1.1 upgrade on it and compare with my powerbook running version 1.0. yes it opens itunes in 2 seconds and make me feel like i was merely maximize the window from hiding. BUT HEY... this computer cost me over £2000 (that's about $30000?) and it's a laptop that you can't leave it on your lap, a macintosh that is not as stable as a windows server 2003 (that's wat i got on my only pc , im a geek and i own a pile of different computers). i didn't want to mention the whine and other famous bugs because that's not an issue to a geek whos room is filled with eletronic noises and i use wired connection for maximum speed so my airport wont drop.
but i'd rather send my powerbook 17 to daystar and get a 2.0 G powerg4 upgrade if i have a second chance.
over.

You misunderstand the memory management scheme and misinterpret the display you're seeing.
To start with, free memory is wasted memory. Once some disk contents have been brought in, it is wasteful to discard that data just to make the RAM that it occupied "free." Inactive memory is memory that is not currently used, can be given to an application that needs it without doing any disk I/O (or used as a destination for reading disk content) but which currently holds disk data that might be useful in the future. I.e., it's file content of some sort.
To get a better idea of how Mac OS X manages RAM and how to interpret the Activity Monitory dispaly, see this tech note: Mac OS X: Reading system memory usage in Activity Monitor.
Rosetta is indeed memory hungry, but it's an interim solution. With 2 GB of RAM installed, you can run a lot of applications with alacrity.
Lastly, your Safari, an Intel-native application, is currently using 2 GB. This is a known issue with Safari, though it seems to me that it has gotten better since 2.0.3 was released in 10.4.6. Still, it's a bit of a memory hog, to be sure. Now that Firefox, Camino and Seamonkey are all available in Universal (Intel native) forms, you have alternatives. Firefox seems a lot more parsimonious when it comes to RAM.

I am trying to dowload pictures onto my macbook pro, but it wont read the USB adapter were all the photos are on?

Hey guys i got a macbook pro and this is the first incident that has happended to me sence i got it i cant figure out why it wont let me download pictures off my usb adapter it wont read it? help

So from your description, the drive isn't mounting on the desktop?
Open Disk Utility (Applications > Utilities), and see if the drive appears in the left pane. If it does, but it's greyed out, highlight it and wait for a few seconds - eventually the Mount button should become live - click it and see if that clears the problem.
If not, it's possible that the drive has been damaged, usually by removing it without unmounting (ejecting) it first.
If you have access to a Windows machine, it may be possible to mount it on there, eject it properly and try again on the Mac. This has been known to work reasonably frequently.

My non retina macbook pro mid 2012 will read the display its connected to but does not display anything at all

Hi there,
I have a macbook pro mid 2012 non retina display and i tried using an external display for it. I hooked it up and the screen blacked out and turned back on like normal and the computer itself was reading that the display was there. The only problem is that on the display itself there is no image of the macbook being displayed. im using a thunderbolt to vga connector and all the connection check out the only problem is the display. the display works on my other macbook that i have just fine i dont understand why it wouldnt work on this new one. Keep in mind i have had this computer for only 5 days.
Thanks in Advance

Hi, cubingcouple.
Thank you for visiting Apple Support Communities.
I understand that your MacBook is not working with your external display. display shows a blank screen. Here is the best troubleshooting resource to go through when experiencing these symptoms.
