Just replaced battery on MBP, and seems that fans run at higher rpm/louder
Hello all;
Tell me that I'm crazy, but I just replaced my MBP battery with a brand new OEM MBP battery and it seems that the fans are running at 4K rpm constantly now. With my just replace old battery, the fans would stay around 2K rpm.
Is this normal? Seems quite annoying. The older battery is ~1 yr old, and had very poor statistics on life and cycles. I accept the fact that I had to replace, but this fan noise is driving me CRAZY!!!
Hi TooManyApples: It may be an activity using too much of the CPU. Check by going to Applications > Utilities > Activity Monitor. Select CPU at the bottom of the page, sort by CPU column, and be sure to select "All Processes" from the drop down list at the top of the page.
Hope this helps
Stedman

IMac fan runs a High RPM and screen goes black after 10-15 min
20" iMac 2.66 purchased April 2008.
I know this has asked elsewhere most likely but I thought I would start fresh.
A few weeks ago my cooling fan started running at high RPM, with really no reason (sitting idle with no applications running). Less than a week later my screen would go black about 10-15 minutes after startup (computer stays on and fan still running). If I re-boot the black screen just appears more frequently (maybe two minutes sooner each time)
Of course I am just outside of my Applecare coverage window!
Also, I have a MBP and would like to access my iMac hard drive. I can't remember what commands to push to access another Macs hard drive.
Thanks for your thoughts and help!

I think you are referring to Target Disk Mode.

Temp and Fans running at high rpm
My CPU A is running at 93˚F and both fans are running over 6000 rpm. I've checked permissions and verified, did a system shut down, removed battery, disconnected power and help power button for 5 secs for restart and still fans noise is extremely loud. I've checked activity monitor and everything seems fine. Anyone have any other ideas to make this machine run cooler and with less noise? I recently added Adobe software updates.
Some versions of iStat Pro were implicated in "wake from sleep" issues especially when "Network" was turned "On" in the settings, PB1701.
It is generally a reliable piece of software though. Personally I prefer Marcel Bresink's "Hardware Monitor" - http://www.bresink.com/osx/HardwareMonitor.html , which provides additional information and runs as an app, rather than a widget. It also allows you to generate ongoing "history" graphs, which can be useful in tracking down "high stress" activities and the like. (A Hardware Monitor "widget" is also available for those who like such things)

ODD and CPU fans running at high RPMs
Hello!
My iMac's ODD and CPU fans are running at unusual high speeds. If I turn the computer off and on they usually run at a normal rate but start rotating at around 3700 RPM very quickly (about 1-2 minutes after the OS X has started). The CPU load is not unusually high. The HDD fan is not affected.
I have tried SMC and PRAM resets multiple times.
27'' iMac - Mid 2010 (iMac11,3)
Intel Core i7 2,93 GHz
Boot-ROM-Version IM112.0057.B01
SMC-Version 1.59f2
Thanks!For some reason the high fan RPMs had to do with having two desktops under mission control.

I just replaced my airport extreme and now the amber light on my airport express is blinking. When I go to utilities and try to find the airport express it does not show up.
What should I do?Anytime you change networking hardware it is always a good idea to perform a complete power recycle of that hardware. Check out the following AirPort User Tip for details. Please post back your results.

I just replaced my hard drive and restored everything from Time machine. However, I am unable to open iphoto and the following message appears Your photo library was not found. Do you want to find your iPhoto Library?
Where do I find this library?
thanks
ShakTwas quite a hassle if I am honest which was eventually resolved but I don't feel qualified to help anyone through the process as it required a trip to my local apple store and a genius bar appointment.
Personally, I would do anything like moving pictures out of folders etc. Certainly not creating a new users. i don't think that is an elegant solution
Try the following which MAY just about rescue the situation for you but if they don't work you may have to do something more drastic.
(1) Holding down Cmd & Alt at the same time, start iPhoto by clicking on the iPhoto icon. From the resulting menu choose Rebuild photo library by selecting all available options given to you and then pressing REBUILD!
If that doesn't work
(2) Fire up Utilities. Go to migration assistant. Chose 'From another Time machine back-up'. Open the 'Users' option that comes up next and from there select Pictures, then uncheck everything else like Applications etc (you don't want to do a full migration of everything) and click go.
If that doesn't work, take a deep breath and this step is rather complicated but it worked for me. First of all close iPhoto! Then go to new Finder window.
From the Finder window choose Pictures, then iPhoto library, press CMD and the letter i. It brings up a new window. Go to Sharing & permissions. From there select the padlock to unlock settings. and then select User account, then press the 'cog' icon next to +/- abd choose Apply to enclosed items.
This may take a while. Once completed, re-open iPhoto.
And that should (I stress should) cure it.
Good luck. -

Hi, I just started a new movie and the program is running very slow. Is there a way to clean up my iMovie program so that it goes faster? Please help.
There is nothing you can do with iMovie program itself. Slow response in usually due to a shortage of system resources (CPU, RAM and disk space).
How much free disk space do you have on your boot drive and what is the capacity of the drive?
You can check memory utilization while running iMovie using Activity Monitor (in Applications/Utilities). What does the Memory tab show for Swap used?
Are you running many other processor-intensive applications a the same time?
If you have a lot of events and projects, it will help a bit to hide the ones you are not using by moving them from your iMovie Projects and iMovie Events folders into an enclosing folder so iMovie doesn't load them.

I just replaced my hard drive and restored everything from Time machine. However, my itunes is empty. No music, movies etc are there. Please help thanks
Empty/corrupt library after upgrade/crash
Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
Windows images, but you get the point. Depending on the age of your library the library file might not include the .itl extention. Make it match the file you are replacing.
See MusicFolder Files Not Added and Super Remove Dead Tracks for tools to catch up with any changes since the backup file was created.

My MacBook Pro is three years old and seems to be running slower. Ideas of what to do?
My MacBook Pro is three years old and seems to be running slower. Any ideas?
Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software -- potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions -- they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are four lines of text in monospaced type, which are actually shell commands -- little programs. They’re harmless, but they must be used exactly as given in order to work.
First and most important, don’t run these commands until you have verified that they’re legitimate. Never execute shell commands from an untrusted source without knowing what they do, or at least that they don’t do anything harmful. I’ve posted these same commands, with minor variations, many times on this site. You should be able to find other discussions in which they were used without ill effects. Do that before proceeding.
Some of the commands will probably line-wrap in your browser, but each one is really just a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
To begin, launch the Terminal application; e.g., by entering the first few letters of its name in a Spotlight search.
Step 1
Copy or drag -- do not type -- the line below into the Terminal window, then press return:
kextstat -kl | awk ' !/apple/ { print $6 $7 } '
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.)
Step 2
Repeat with this line:
sudo launchctl list | sed 1d | awk ' !/0x|apple|com\.vix|edu\.|org\./ { print $3 } '
This time, you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.
Step 3
launchctl list | sed 1d | awk ' !/0x|apple|edu\.|org\./ { print $3 } '
Step 4
ls -1A {,/}Library/{Ad,Compon,Ex,Fram,In,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Sta}* 2> /dev/null
Important: If you synchronize with a MobileMe account, your me.com email address will appear in the output of the above command. Change it to something like “[email protected]” before posting.
Remember, this is all drag-and-drop or copy-and-paste, whichever you prefer -- no typing, except your password.
You can then quit Terminal. -

I just ordered a macbook mc207ll/a online that is running Sow leopard, will I be able to upgrade to yosemite?
Just make sure you update it to 10.6.8 (the last version of Snow Leopard) once you get it if it isn't running it already. Just go to the menu and then Software Update. This will give you access to the App Store which is needed to download Yosemite.
