My MBP runs hot in the boot volume selection menu

I noticed that when I start my MBP holding shift to get to the boot volume selection menu and leave it there for 15 minutes or so (might be shorter, I was gone both times that it's happened so far) the MBP gets unusually hot (almost too hot to touch between keyboard and screen) and I can hear the fans going much faster and louder than they should be (I think). After choosing one of the boot volumes and checking the temperatures in iStat Pro I see that the CPU is at just under 70°C. A few minutes later the temperatures go down by about 10°C and the fans quiet down running at the usual 2000rpm.
Why does it get so hot? How can a simple boot menu be consuming more resources than a full desktop environment plus open Dashboard (which FYI contains 20+ widgets).

Answer: yes, it does.

After Mavericks Install, MBP runs hot all the time

Im sure this has been said all over the community but I have to add my two cents. My 2011 MBP was perfect on Mtn Lion. I started the update which failed on install, which I then had to wipe the HD and do a fresh install. My time machine backup wouldnt even restore, that was a fun night let me tell you. Anyways, ever since I installed Mavericks, not only do I have the service battery issue everyone else has but now even running firefox or watching a movie will make the laptop run super hot and the fans start going. Ive even had the MBP shut itself down twice b/c of the overheating. Example: I almost couldnt even get time machine to make a new first time backup b/c the laptop starting running hot during the backup and it shut itself down. The second attempt worked but it sure seemed like it was on the verge of shutting down again. I just tried resetting the SMC but I dont think it did anything if you want my honest opinion.
I hope apple is listening and realizes what mess mavericks is making of our older macbooks.

I did do the verify/repair disk, and there is nothing wrong with the disk. Havent had a chance yet to boot in safe mode. Will post an update shortly but in the meantime:

MBP running hot when connected to Cinema Display

I have a 2.33 MBP that I use for work and at home. I also have a 23 inch Cinema display on my desk at home. I have noticed that when I have my MBP connect to the Cinema and the screen on the MBP closed it runs hot and the fans never seem to stop running. I was wondering if anyone has seen the same thing and if so what they have done to resolve the issues. I have had looked at the laptop coolers that go under the laptop and that powers the fans off an USB port, but I really like my desk clean and don't want to add something else to it. Any ideas or suggestions would be great.
Thanks
Matt

Try running with the lid open and see it temps drop.

How can I view the boot volume permissions?

How can I view the boot volume permissions in the Terminal and/or Single User Mode?
I have tried: 'ls -l /Volumes' but this appears to only work for the non-boot volumes. I can test this by 'sudo chmod 777 /' followed by 'ls -l /Volumes' but the change is not reflected by the new list.

I prefer to have my bootable volumes as follows:
drwxrwxr-x
I see no point in allowing others to write to / and sticky here often gets in my way. Can you see anything wrong with this?
I couldn't say, as I let Mac OS X do what it wants with the / root directory. I don't know how sticky can hurt, as you need to have elavated privs to do anything in root anyway.
But if it is working for you, have fun. Just make a note to yourself somewhere that you have made this change, so that if something stops working, you can take this change into consideration. And if this change does not cause problems, but does something useful for you, you can use the note to remind yourself that you need to re-make the change when installing a new system. So take notes on your changes. It will make your life easier in the future.

My new macbook air 10.7.3 is running hot with the fan blowing just by using the internet. Is there something wrong with the computer?

My new macbook air is 10.7.3 s running hot, with the fan blowing after about one hour on the internet. It will also run very hot with the fan blowing when it is closed and in sleep mode, is this normal? My macbook pro did not do this.

May 19, 2012
My Macbook Pro 15" Early 2008 model had been running hot for a long time.
Checked Activity Monitor. (Applications/Utilities)
AdobeResourceSynchronizer was taking 83% of CPU usage.
Did a google search and found information regarding AdobeResourceSynchronizer causing high CPU usage and heat.
http://forums.adobe.com/thread/822790
Problem seems to be Adobe Resource Synchronizer.app
To disable go to: System Preferences > Accounts
Click the Padlock icon, enter password if needed, click Login Items,
uncheck AdobeResourceSynchronizer
I don't know how this got install on this computer.
I suspect Adobe Reader. AdobeResourceSynchronizer.app is within the Adobe Reader application package.
Control Click (or right click) the Adobe Reader app, click Show Package Contents
Location: Applications/Adobe Reader.app/Contents/Support/AdobeResourceSynchronizer.app
Some other Adobe applications may also cause this to run.
After disabling this in System Preferences > Accounts, temperature seems to be acceptable.
Also start Adobe Reader X, go to Preferences, Tracker and in the "Automatically Check for New Comments and Form Data", slide the top slider all the way to the right so is says Never.
After having done all this and restarted the computer, check Activity Monitor again and see if
AdobeResourceSynchronizer is still running. If it is you can click on it so it is highlighted and click the Quit button in the upper left.
This solved my excess heat problem.

Will the new 2TB time capsule run hot like the old one?

Could someone please tell me if the new 2TB time capsule that just came out will run hot like the old version? I have been thinking about getting the time capsule for quite some time, but I am concerning that it will get overheated to the point that all the data stored on it would be lost. I have seen several posts over the internet mentioning this problem. Please help. Thank you so much.

I just replaced my old TC with the new one. It took all night to transfer 149gb from my Imac to the new drive by wireless N. I took the old one to work and hooked it up in my office for a back up of a Mac Mini. At home we had 3 Mac's attached to the TC and it was always hot.I even found some sockets from an old socket set to raise it up so air could get under it to help cool it down a little. The new one is just warm with the same computers hooked up. The old one at work is also only warm to the touch with the one Mac hooked to it. I'm very happy with the new one and love the dual band.

Equium A110-233 - I need select manually the boot device from menu

In the last few days when I turn on my laptop the Toshiba screen appears but I need to manually go in and select the boot device to start windows.
(Down the bottom the message 'Press F2 for set up. Entering boot device selection menu')
Why has this started and what can I do to get it to go straight into Windows XP like it used to?

After switching your notebook ON please use F12 button and you will be able to select the first bootable device.

Why is the Boot Disc Selection screen always appearing?

WIth a bootcamp partition on an iMac booting while holding down the Option key will cause the boot disk selection screen to appear, but suddenly I'm getting the boot disk selection screen even WITHOUT holding down the Option key. Why?

Well it might take a little longer since POST (power-on self test) needs to check more memory.
But try doing a smc and pram reset and see if that helps.

Does the new MBP run hot?

I'm looking to buy the new MBP 15". Does anyone know if it runs hot? My current white polycarbonate first generation Intel Macbook always runs ridiculously hot.
Thanks!

Picked up a new 15" very recently. Subjective heat evaluation:
9400M: Very cool during general use (web browsing/email/etc...) Warm during gaming (WoW).
9600M GT: Warm during general use. Hot during gaming. VERY hot in Windows, gaming or not.
Of note, Windows only sees the 9600M GT, and gets uncomfortably hot (to the point I'm not only uncomfortable using it on my lap, but feel like I ought to be pointing a fan at the bottom-left (where the GPU is located).
The laptop was never uncomfortable on the 9400M, even while running WoW with the laptop directly on my lap. Just pleasantly warm. Same circumstances with the 9600M GT enabled I needed to throw a lapdesk under it, but it didn't get nearly as hot as under Windows.

MBP running hot, full fans and sluggish with both Safari and Firefox

Hi guya,
Im having problems with my kate 2007 MBP.
Im sure lately it seems to be running slower and slower and more and more sluggish - I was hoping my Mac wouldn't be subject to "slowdown" like every PC ive ever owned has.
The biggest problem is that if i use either Safari or Firefox to browse the web, they quickly start using 80-100% of my processor causing everything else to run sluggish, the computer to get hot, processors to run up to 90 degrees and fans on full.
Perhaps i multitask more than some people - I can tend ot have a lot of tabs open in Firefox, but sometimes Safari or Firefox show this behaviour with just one tab open.
I do multitask by having about 8 programs open at once and I jump from job to job, but in its early life the MBP used to deal with this - now i feel that i type faster than writing appears on screen, i have to wait ages to work in programs like indesign, and forget trying to run a game like The Sims...
Does everyone else have the 100% processor problems with Safari (and yes im on version 4, and the latest version of firefox too) the only browser which doesn't give me these problems is Opera - I can have many tabs open and it uses very little CPU, I just dont like use Opera as much as Firefox which is my browser of choice.
But why would my OSX run differently to anyone elses? Is there a problem with my Macbook, is there a problem with OSX (does it need installing again?) Is it just time for me to buy a new Macbook Pro - or if I run firefox on that will i get the same problem? Ive got nearly 30gb of spare HD space and maxed it out with 4gb of Ram - so neither of those are causing a problem either...
Any input would be great...

Have you tried restarting the comp? Sometimes a simple refresh will cure the sluggishness.
Try running repair permissions from your HD and afterwards run +repair disk+ from your software install DVD.
Regarding your comp running hot, make sure it is properly ventilated while in use. The MBP is not a laptop. According to the user manual it states in part:
+"Do not operate your MacBook Pro on a pillow or other soft material, as the material can block the airflow vents. Never place anything over the keyboard when operating your MacBook Pro. Never push objects into the ventilation openings."+

MBP Running Hot & Slow

MBP 2008, 2.53 GHz Intel Core 2 Duo, 4GB, Snow Leopard 10.6.8
Over the last few weeks I've noticed frequent spinning parasols and what seems like generally slow performance. However I was truly shocked when I worked on my wife's cheapo Windows 7 Toshiba, it was lightning compared with my MBP.
Now the MBP is running very hot with the fan frequently screaming, even when CPU is 40% idle (which I think is relevent).
Does anyone have any suggestions, or where I could look for the problem?

Disconnect all wired peripherals except keyboard, mouse, and monitor, if applicable. Launch the usual set of applications you use when you notice the slowdown.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
Select the CPU tab. Select All Processes from the popup menu in the toolbar, if not already selected. Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Now select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Step 2
Launch the Console application in the same way as above, and select “kernel.log” from the file list. Post the dozen or so most recent messages in the log – the text, please, not a screenshot. If there are repeats, please post only one example of each repeated message.

I have a macbook pro 10.6.8 system. My hard drive was replaced under warranty. Since then, my computer runs hot. The original hard drive never ran hot. What would cause the new hard drive to run hot?

I have a 2011 MacBook Pro, OS X 10.6.8, 2.2 GHz Intel Core i7, 4 GB 1333 MHz DDR3. This is my first computer so don't know anything about trouble shooting. A week before the warranty expired, I took my computer to Apple to be checked. I was told that my hard drive was bad and they replaced the hard drive. Since then, my computer runs hot most of the time and the fan is constantly coming on, which is good My computer rarely ran hot with the original hard drive. What would be causing this?

racergirl,
have you tried resetting your MacBook Pro’s System Management Controller, to see if that makes a difference with the heat?

G505s running hot all the time

So I have my G505s (still under warranty thank god) and has been running fine but now it seems that the fan isn't running anywhere near the percentage it should be. I have run energy management fan cleaning, bios is updated, AMD overdrive is downloaded... but it is physically hot and the fan does not change rates of speed. Yes, the power management setting is set at active... I am not even running anything and it is running hot.
Is there a driver or patch that alters the temperature protocols? Because if the fan can run faster, but isn't even when it is hot.... then it isn't serving the purpose.
Lenono please help me... and the fact this is a consistent problem isn't prompting me for reccomendations. If this continues I will be getting the laptop serviced under warranty or replaced because this is ridiculous.
I do run windows classic shell, but that has not been a problem yet.

hi reedbarnes,
Welcome to the Lenovo Forums.
Just to check, when you open AMD Overdrive, what are the values on the CPU frequency and temps?
- Sample image
In addition,is the system running on BIOS v3.00? Looking at the BIOS 3.00 - Summary of changes, this should fix the fan duty if you're getting CPU temps. between 50-90°C.
If you have the BIOS to v3.00 and you're getting high temps (eg. 60°C++) after logging into Windows and there are no startup apps / processes running on the background that's eating up high CPU resources then it's likely that the fan may need to be replaced (or the thermal paste and heatsink as it's not properly conducting the heat out of the APU). In this case, you may need to contact lenovo and report the issue as you may need to send the unit for service.
