Why does mountain lion run hot on my macbook pro?
After up grading to mountain lion my macbook pro now runs very hot!!!
Same problem here,
I used third-party software to manualy regulate the fans, to minimize the "damage". My CPU temp on my MacBook Pro went up to about 75.0 °C (167.0 °F). And the alu-body also gets incredibly hot. For monitoring I used iStatPro.
The application integrates nicely into the system-settings menu and there's very little that can do wrong.
I set my Base fanspeed to 3000 RPM
Lower threshold to 40.0 °C (104 °F)
Upper threshold to 70.0 °C (158 °F)
I don't really see this as a long-term fix, but more as a messure to save my hardware.
Hopefully Apple will look for a fix. I really whished I didn't need this, but it's either this or a scorched lap/battery/cpu.
PS.- I think this topic is related to: Battery life dropped considerably on...

How well will Mountain Lion run on the following MacBook Pro?
Thinking about biting the bullet and upgrading to Mountain Lion on my MacBook Pro. My specs are as follows:
MacBook Pro 15"
(Late 2008 model MacBookPro5,1)
Intel core 2 duo 2.53Ghz
8GB RAM
1TB HD with 390GB free
Mac OS X 10.6.8
So, how well will Mountain Lion run on this configuration? Currently I'm finding my computer annoyingly slow, so am wondering whether an upgrade was worth trying or not?
Any advice would be most appreciated!
Thanks!
Joe.Sorry, I should have been clearer - that's what I was thinking, which is why I was asking the question. I thought that if I was going to all the effort of a reformat etc that I should just upgrade to Mountain Lion while I was at it, but didn't want to do that if it was going to run really slowly anyway and then have to go through it all again to go back to Snow Leopard.

So, have you had any personal experience of Mountain Lion running fine on this MacBook Pro? I know that officially it will run, but I'm wondering about the "real life" experience of it running on this model.
Anyone out there able to share their expeience? -
Why does Mountain Lion triggers front fan in Mac Pro?
Hi all, this is my first visit to this community and I hope there won't be much more .
I bought a new SSD drive for my Mac Pro (early 2008). I had to install it from my Macbook Pro because Leopard in the Mac Pro wouldn't allow me to.
Neither I could perform a bootable USB clean install since the Mac Pro didn't show the device in the drive selection splash screen.
Then I put the SSD back into the Mac Pro and eureka, everything worked just fine. After about 30 seconds with the desktop in front of me, the front fan of the Mac triggered like if it was a constant reboot. However, the system worked just fine with no trouble but the annoying noise of the fan.
It's an OS related problem because this doesn't happen in Leopard. Any idea what went wrong?Faulty installation. Why could you not install the SSD in the Mac Pro running Leopard? Why are you running Leopard in the Mac Pro instead of upgrading it to Mountain Lion? Try doing it this way. Put the SSD into the Mac Pro.
Erase and Install
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your SSD (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. After formatting finishes quit DU and return to the installer. Install Leopard onto the SSD.
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
Snow Leopard General Requirements
1. Mac computer with an Intel processor
2. 1GB of memory
3. 5GB of available disk space
4. DVD drive for installation
5. Some features require a compatible Internet service provider;
fees may apply.
6. Some features require Apple’s iCloud services; fees and
terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
Lion System Requirements
1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
or Xeon processor
2. 2GB of memory
3. OS X v10.6.6 or later (v10.6.8 recommended)
4. 7GB of available space
5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
OS X Mountain Lion - System Requirements
Macs that can be upgraded to OS X Mountain Lion
1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
7. Xserve (Early 2009) - Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.

Why does mountain lion "bunch up" all my microsoft office documents that I have open when I hit f3? When I had snow leopard for example, if i had 4 or 5 different microsoft office documents open at the same time I could hit f3 and easily pick one of them.
Notice how in the photo, I can't identify which MS office document I would like to switch too. Perhaps since the Dashboard and Desktop windows are at the top of my screen now Apple doesn't let you have all the applications take up the full screen and be sized individually so that you can have a better idea on what to pick.
I like the idea of grouping to an extent... If you have a bunch of random things it was hard for me to decifer between what was safari, chrome, or word. But now that they grouped them like this, if you have multiple pages of one program running, you can't switch between those pages easily like before.If I wanted to open any of my Applework documents I had to open them one at a time and resave them with pages. This could take weeks.I have 1000s of apple work documents.
You don't have to open and re-save every AppleWorks document you have right now. Just wait till you need one, then do it. The documents aren't going anywhere.
Am I dealing with Microsoft? This was a BIG surprise to me that Apple would release an OS without testing all programs.
Frankly, it is not Apple's responsibility to ensure compatibiltiy with every piece of software available for OS X. That is the responsibility of the software vendor. Lion has been available to developers for several months before it's release, so Microtek had plenty of time to update their software. Yet they did not. How is that Apple's fault? I think Apple was very generous to give you a refund for Lion.
I'm not trying to belittle your frustration but I do think your ire is misplaced. -

Mountain lion won't install on macbook pro 3,1
We have a MacBook Pro version 3,1 computer with 10.6.8 running.
Plenty of disc left, 2 Gb RAM.
The install process goes in a loop, from app store to www.apple.com/osx to pushing the "upgrade" button and back to the app store page.
I'm not really a Mac kind of person, it can tell.
I ran a hard disk utility to check and correct permissions but it didn't help.
any thoughts out there? I just want to run lightroom 5 and it needs 10.7 or better.
Can I buy 10.7 someplace?
Thanks
DarrellHello darrellsmith,
While i currently have no solution or suggestion for your problem, i would like to mention that even though Mountain Lion technically supports your model MacBook Pro, i advise against upgrading to mountain lion. It will put significant strain on your system resources and most tasks will perform very slow. If you really do need Mountain Lion, at least upgrade your RAM to 4GB. I know that 2GB is the minimum requirements but you'll lose those 2GB by just booting up and starting Safari. Add the software you want to use on top of that and your performance will be severely impacted.
Also, make sure you have a good backup of all your data. Upgrading an older system and skipping a major release in the process can create some issues or bring issues to light that you already had but just were not aware of.
A possible solution could be to create a bootable installer on an external drive, instructions can be found here.
For your system, OS X 10.6.8 would be the recommended OS and will give the smoothest performance. You will, as you've noticed, be limited to the applications you can run. -

Realize that people that aren't having problems tend not to "brag" that they're doing fine. Those that are having problems are usually very vocal. So a lot of the "bad reviews" may just be those that had a problem, not necessarily the real experience of the millions of people that are doing just fine.
...and I'm afraid to download it and my computer is 2009, yours runs smoothly?
I'm running Lion fine on my 2008 MBP (4,1. 2.4GHz C2D, 4GB) and late 2009 Mini (2.0GHz C2D, 8GB.) Minimum RAM for Lion is 2GB, but IMHO you really want 4GB. If you have a lot of apps open (or have demanding apps like Photoshop,) then get more RAM if you machine can handle it.
Also, make sure the rest of your apps or drivers are up to date before upgrading. Incompatible drivers for things like printers and such are what I've found to cause a lot of stability problems. -
I had a copy of Mountain Lion on my late 2008 MacBook Pro, having replaced Lion which it came with. But the drive crashed, so I replaced the drive and reinstalled Lion from the original disks I had. How do I get another copy of Mountain Lion?
A 2008 Mac won't have originally shipped with Lion. You need to install 10.6.8 on the computer, log into the Mac App Store with the Apple ID you used to purchase Mountain Lion, click on the Purchases tab, and download it.

Since installing Mountain Lion, all three of my Apple computers are running hot. Also it takes more time to open most applications and run programs. Does anyone know what's causing this? I am using a iMac 27, a Mac mini, and a MacBook.
From reading the forums, I think it's running a bit hotter for everyone. foxx is right, download smcFanControl and you can raise your baseline fans from 2000 to 3000 and see if that helps.

Why does Mountain Lion stop downloading at 10mb?! HELP!
I keep trying to update my operating system to Mountain Lion. Everytime I download it, it downloads up to 10mb and then restarts back to zero. It does this
three times and then gives me this error: "The application could not be downloaded. Check your internet connection and try again" I have done EVERYTHING I have read online from other discussion groups and websites. My internet connection is fine...I've even plugged my iMac directly into the cable and router....my computer is compatible, newer, and has enough memory....I've tried "unhiding" my update purchase...I've tried with my computer in safe boot mode... I have gone through every troubelshooting step I could find, and can't get mountain lion on! PLEASE HELP ME!!!!Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up guest users” (without the quotes) in the search box. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.
Test while in safe mode. Same problem?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.
