Fan settings for imac

What are the appropriate fan settings for a 3.06 GHz Intel Core 2 Duo processor?

Why are you messing with the fan settings? The system will take care of those things for you. By playing around with low level system settings you can end up doing more harm than good. Are you having a specific problem with your fans? You might first want to check your temps to determine which fans(s) are acting up. Some fan issues can be corrected by resetting the SMC.
To reset the SMC
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.

Fan Control Software for iMac G5

do you know any software that makes me able to control the fans of my imac. I want to change the speed of my fans.

You can control the fan speed to a certain extent by going to system prefs>energy saver>options>processor perfromance and selecting "reduced". This should slow your fan speed down, but I am not aware of any software program that will contriol your fans speed. It wouldn't be a good idea anyway to interfere with the settings the machine selects for itself, the iMac is very sensitive to heat and shouldn't have fan hacks.

Sometimes, a replacement 1/2AA 3.6v Lithium PRAM battery is needed
to get these back into running form again, because these are one-way
and without a good battery, settings are lost or easily corrupted. And this
can contribute to a failure on startup. But that is a troubleshooting measure.
There could be another issue, although these batteries are only good for a
few years at best. A power outage can revoke any remainder of life out of it.
The take-apart is tedious and detail oriented; to include new thermal paste
and some special tools, good instructions, and some skills also help. An
ifixit.com repair guide may help; as would an original Apple Service guide.
Not sure if other good online guides or youtube video are available.
If the power supply is bad, the test ports near the PMU button are where
to check; with multi-meter. Also power supplies may develop issues with
bad capacitors. They have been said to be repairable.
Here's an older site with a take-apart from some time ago.
http://www.xlr8yourmac.com/systems/imac_g4/imacg4_takeapart.html
This also would be a good time to consider, if battery is all that's failed, to
upgrade the internal RAM chip, or upgrade the hard disk drive, etc.
Good luck & happy computing!

What are the settings for iPhone, iPad and iMac to sync ical and contacts?

How can I get all three items to sync? What are the settings on the iMac with Lion on board? I put all my stuff on iphone but iMac & iPad do not have the items synced even though I have everything on icloud?

They're asking a question about carrier settings for their iPhone. I think that has everything to do with Apple.
Maybe they did already ask Straight Talk. I've called Straight Talk before... they're not too helpful.
You know, this forum would be much friendlier if people in this forum would quit squabbling, & posting comedic replies, not too mention name calling (like I did), when people are just needing some help.
It's also frustrating that people stick up for the guy who doesn't help, but rather takes the time to post some smart alec reply. Granted, I shouldn't have name-called... some people just frustrate me when they act like that.
Admittedly, there ARE some grey areas when it comes to carrier questions... but let the moderators do their job when someone is asking innappropriate stuff. And if the mods aren't chiming in, then that's a good indication that what the thread is about IS in fact Apple related.

Open Messages and choose Preferences from under the menu bar program's name and add source accounts to use.

Can't update. Message says I don't have all permissions, yet have admin rights for imac running 10.5.8 & checked preference, security settings.

Trying to update. When I drag ff icon to apps folder message says replace or stop. Answer replace, then message says can't complete as I don't have permissions. I have full admin rights for imac running 10.5.8. I've reviewed preferences & security settings, FF is set to accept all incoming connections. Not sure what else to check.

If there are problems with updating or with the permissions then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.

Can you do setup an unread mail folder that shows all unread mail regardless of what folder it really is in on the iPhone mail program somehow?
No.
If not, can this be submitted as an enhancement as it makes email use very cumbersome.
Yes. You can submit feedback to Apple: http://www.apple.com/feedback/iphone.html.

Best settings for mp4 video for ipod and watching on imac (apple tv)

Try converting using iSquint (just google it). This should be good.

User-developed Fan Control for the S10(e)

Hello and welcome.
When you've searched the internet and found this thread, it's possible that you are an owner of a Lenovo Ideapad S10 or S10e which has a little problem with the behaviour and/or the noise of the fan. In this post you will get all the informations you need to handle this problem for yourself. It should also be the same on every S9/S9e.
Just a few comments before we begin:
This is not an official support or solution by Lenovo.
We are just normal users as you are, but we get rid of the fan and wanted to find a way to handle it. So if you want to try anything of the methods described here you have to know that you'll do all this only at your own risk. We are not responsible for any damages of your device. You should only use these methods if you know what you are doing.
Please note that this thread is only for discussing, improving, trouble shooting and perhaps extending the fan control utilities. Any general complaints about the fan problem itself should be placed in the original thread right here: http://forums.lenovo.com/lnv/board/message?board.id=IdeaPad_Netbook&thread.id=795. It already has 80+ pages (the link goes to the first page) and it is better to exclude all the fan control stuff because there it's very difficult to keep an overview.
Here you may post all of your questions, ideas/brainstorming, concerns, thanks and so on and you are really invited to participate and be an active member.
In this first part of this post I'm going to summarize all information about using a fan control utility. For any newbie it will be enough to read this post to get all necessary information. The second part does the same for developement of fan control utilities as we still have no known or working fan control utility for Linux, Mac OS X and other OSs I've forgotten - for now.
For getting started you need a S10 or S10e with an up-to-date BIOS. For the S10 it's the 90 67, for the S10e the 66.
The battery issue
Under very specific circumstances - that we haven't figured out yet - it might happen that your Lenovo S9/10(e) no longer detects the battery while using S10FanControl or S10Fan. It might occur after 2 minutes, it might occur after 2 months, it might never occur. It does not occur using Notebook Hardware Control.
It can be solved by removing the battery, waiting 10 seconds and put it back in. Then the battery is re-initialized and the detection works again.
S10FanControl - Windows
The first utility is S10FanControl created by user dresslerc. The current version is 1.0.0.1, available here: http://www.mediafire.com/file/yd5xmnrnijf/S10FanCtrl1.0.0.1.zip. After you've downloaded it you just have to extract it and start the .EXE in the "Release" folder. Here are the notes and the description dresslerc posted right here:
Everyone,
I've uploaded a version which everyone can use to test with. Remember this is still a TEST version although I think it works for the most part. It should work both on the S10/S10e.
Please install the .NET Framework 2.0 or later first.
Then click here to download the exe: http://www.mediafire.com/?jlg2enkjdxn
Once downloaded, extract the files and hit hte S10FanCtrl.Exe. Once this program launches you should be able to control the fan. Keep in mind that if you lower the fan speed then it'll take upto 30 seconds before the S10 registers the change, so be patient.
I've only tested this on the latest BIOS 59. I am sure it will work on the 57 as well but the individual speeds might not work properly on that version. Please try it out and report back.
The only issue that I heard so far is that occasionally the fan will kick in regardless if in Manual/Smart Mode. Also the temp it shows may not be accurate. If you find any other issues please let me know what they are so I can attempt to fix them.
Once we have all the kinks worked out then I will release the source.
Heres a quick Video: http://www.youtube.com/watch?v=_PKl70ZgmFg
REMEMBER: USE PROGRAM AT YOUR OWN RISK!!! I AM NOT RESPONSIBLE FOR ANY DAMAGES THIS PROGRAM MIGHT CAUSE.
Application Use:
BIOS Controlled - Fan is controlled by the BIOS
Smart Mode - Fan is controlled based on the conifguration in the options. You can set the threshold here at what temp you want the fan to kick in...
Manual - Fan is controlled manually by the slider.
If you want to have the program startup automatically, then place a shortcut of the app in the PROGRAM FILES -> STARTUP folder. Then you may want to go to the options and make the application minimize at startup.
Edit:
It seems there are some issues with the app and the S10e or previous BIOS versions. Will post a fix asap.
The source code for S10FanControl is available here: http://www.mediafire.com/?sharekey=7a3fb99d33817c08c2b435915e8821d7e04e75f6e8ebb871, written in Visual Basic .NET 2008.
S10Fan - Windows
The second utility is a tool written by user slash:
Hi guys,
Well it looks like Lenovo dropped this matter after all. Anyway, I have here another fan controller to add to the bunch. I have been using it for some time now without any problems. It is for both S10 and S10e.
What the program does is basically the same as others. The S10's fan speed is controlled according to the ACPI thermal zone temperature. By over writing the values which resides at offset 50h of the EC register at an appropriate timing, the ACPI thermal zone temperature is over ridden. The program is written in C and uses WinIo created by Sysinternals. The GUI version is available now.
It should be noted that the fan speed temperature thresholds differs with BIOS version. For 14CN67WW and 14CW90WW the fan changes speed at temperatures 60c, 65c, 70c, and 80c. Furthermore, the BIOS will automatically shutdown the S10 if the temperature reaches 90c.
The program has a fail safe mechanism that automatically disables itself if the actual ACPI thermal zone temperature goes above 85c. This allows the BIOS to regain control and the fan will work as intended by Lenovo. If the temperature drops below 85c the program will take over control again.
To run the program, you will need administrative privileges.
Known working BIOS versions: 14cn58ww, 14cn60ww, 14cn67ww, 14cn90ww
The program will work with any BIOS version as long as the BIOS uses the 50h EC register readouts to control the fan.
build 2009.05.24
Higher priorities for EC commands.
Usage: The program will run in the system tray. Double click or right click and use the menu to open the program. To determine the BIOS temperature thresholds, use the 'Setup' button. To run at boot time, place a short cut in the startup folder.
http://www.mediafire.com/file/njhz0icym2t/S10Fan.zip build 2009.05.23
Usage: S10Fan.exe

Usage: S10Fan.exe 60 65 70 80 70 75 80 85

Notebook Hardware Control - Windows
The third utility is a profile for Notebook Hardware Control. I've adapted it from a profile for the Lenovo N500 which I've found here: http://nhc.yourcopy.de/overview/. With the manual for creating the profiles that can be found here: http://www.notebook-treff.de/board/database/hilfsprogramme-f%C3%BCr-nhc/92-how-to-create-an-acpi-fil... I was able to change the ACPI commands to work on the S10(e).
Installation and setup is divided in two steps. The program Notebook Hardware Control (NHC) is available at http://www.pbus-167.com/. Install the program, but do not start it for now. Then you need my NHCConfig utility, available here: http://forum.eeepcnews.de/download/file.php?id=1476. It detects your model number and BIOS-version via WMI and writes a proper S10(e) profile to the NHC acpi directory. The GUI is German if you have a German Windows and English if not. Additional languages can be added.
After you've extracted the ZIP-file you have to start the nhcc.exe (requires .NET Framework 2.0). At first a message appears that you use the program at your own risk. Then you can choose if you want to apply your own settings (experts) or if you just want the program to run with my defaults (newbies). In the settings window you can see your system details on the left, you can set up your thresholds in the middle and you can set the fan speed you want on the right. Then click on execute.
Now start NHC. Go to the "Settings" tab and click on "Show all NHC options and settings". Then a few more tabs appear. Go to the "ACPI" tab and check if the "ACPI Control System" is running (if everything works, the message "ACPI Control System running" will appear, otherwise it says "ACPI control system is not yet configured for this system"). Now click on "Show ACPI Control System details".
Here you can change the temperature values the fan control depends on (the settings from NHCC are the default values). On the bottom of the window you can see the "Current CPU temperature". That is the value you have to deal with. In general it has a value of around 60°C. In the middle you can see four user editable temperature values. You can leave the values as they are if everything works. The on/off values are responsible for the temperatures at which the fan starts running and stops again after cooling the device. The level values are responsible for the fan speed, for example you can set the off_level higher to let the fan run all the time at the lowest level, if the values do not fit for your device or whatever.
You can switch between NHC and BIOS control by disabling or enabling the "ACPI Control System" or by closing NHC.
Q:
A:
With every utility it is possible that it takes some time until you see an effect after you've started the program. Any failure of the programs should be no big problem because the only thing that should happen is that the BIOS controls the fan. Another issue that might occur due to the way the fan is controlled is that the fan may start running for a very short time and it looks like the fan control has lost control. The fan should stop immediately or at least after a few seconds.
Keep in mind that running the S10(e) with a fan control means that the S10(e) has to deal with higher temperatures. That could mean that the device will not last for 10 years but only 9 years (who uses a netbook so long...?). In every case you need a tool for monitoring your cpu temperature. We know that especially Core Temp 0.99.5 and Real Temp 3.00 do a very good job. That is important because the temperature values you need to set up the fan control are different from the values reported by the cpu sensor, they are between 15°C and 20°C higher. A normal temperature reported by the monitoring should be around 40°C, with the NHC default values the fan starts running at 52°C and stops at 38°C.

Q:
A:
END using fan control
BEGINNING developing fan control
Controlling the S10(e)'s fan is a litte bit difficult because it looks like there is no way to control it directly. But it is possible to manipulate the temperature the BIOS fan control depends on. As long as the built-in fan control thinks that the cpu is cool enough the fan stays off. And that is exactly the point where we can attack.
The fan control depends on a field called RTMP in the memory of the embedded controller. It can be accessed via "_SB.PCI0.LPCB.EC0.ERAM", the offset of RTMP is 0x50 (hex) or 80 (dec). It is a direct I/O read/write. The complete NHC command for reading the value is: ACPI.FIELD.ReadByOffset("_SB.PCI0.LPCB.EC0.ERAM", ref value, 0x50, 8) with "value" as the variable which gets the value.
What program logic do you need? You need a timer or something else that conducts an always-refresh cycle. It sounds very easy: You read the value, manipulate it and write it back. And it is that easy, you just have to keep some things in mind.
This refresh has to be done very often. The procedure must be very thin and quick. Also the bus that is used to communicate with the EC is a problem, but since the S10e BIOS 66 it became a minor problem for me because it looks like the built-in fan control now depends on some kind of average value over the last few seconds and it doesn't really matter if one write-cycle is failing.
The read-event must be placed before the write-event. Otherwise you just read your manipulated value. The field is filled by the system regularly, so you just have to test if the read_value is different from the written_value, then you know that the field was filled with a "fresh" value. Like "if read_temperatue <> written_temperature then real_cpu_temperature = read_temperature else do nothing".
About the values you have to write back... you will have to test and play a bit. My experience is that you can select three fan levels, starting at 59°, 62° and 70° - at least with the NHC profile and my S10e it's like that. It's some trial 'n' error. My fan stays off at < 59°, but you should select a very low value for fan_off like 30°. In my opinion it switches off much faster the lower the written value is. But it's just a feeling, I haven't measured it.

Great opening post Carsten!
The latest bios:
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-71252 (BIOS 66)
The FSB can be reduced from 133MHz to 100MHz using SetFSB, this also reduces the heat:
http://www13.plala.or.jp/setfsb/
clockgen = SLG8SP513V
If you add a shortcut to the startup folder the program will start at startup. Under properties you can change the target to:
"C:\Program Files\SetFSB\setfsb.exe" -s100 -b1 -cg[SLG8SP513V] -w20
So it starts with a FSB of 100Mhz, in the background, with the right clock generator, after 20 seconds.

Would like to buy TC to replace AE for iMac and MBP; questions

hi all--
currently i have a dual-band airport extreme on bridge mode connected by ethernet to my AT&T Uverse wireless router. we have several Airport Express' and an ATV2 in the house and the 2 wireless connections; the g put out by Uverse, and an n put out by the AE. I switch to either one depending on location. I have a WD 1TB drive hooked up to my 750GB iMac via FW800. for years that was fine as the iMac was the main computer and i just worried about it's backups.
now we have upgraded a 2007 MacBook to a new MBPro w/ a 500GB SSD, 12 GB RAM, and an i7 chip. needless to say, now THIS computer has become pimary, as it blazes!! but now since there's so much info on it, it really needs to be backed up as well.
i'm OK with basic/moderate connectivity, but sometimes get confused by more complex issues. so let me throw my wants at you. i'm hoping that i can buy the 3TB TC to replace the AE and WD drive, split the TC drive into 2 partitions, and keep the iMac hooked up to it via ethernet, and let the MBPro back up wirelessly to it's own partition.
i guess this might be pretty basic and obvious, but before i buy all this and sell my old equipment, i'd like to make sure it should work. i've never set up a TC before, but i hope that i can just tell it to use the prior settings for the AE to get most setup issues out of the way. and i'm not quite sure how (or when in the process) to partition the TC drive, assuming i can.
if someone can advise me whether this setup is possible, and how to (or a link on how to) partition to TC drive for the 2 computers that would be fantastic. the main reason i'm unsure about doing this is that on Apple's TC page, they really only seem to discuss all computers backing up wirelessly, which would be silly for the iMac since they're side-by-side.
any thoughts for me, my faithful bretheren?

You cannot partition the TC drive but the two computers can use TM to their own areas without any need for you to intrude.. That part Apple do a good job of. The backup sparse bundle is effectively a disk image and the computer keeps track of it by virtual of serial numbers.. you will have no issues.
And the iMac can use ethernet which will be much faster.. you should do both backups initially by ethernet.. once completed the MBP can backup via wireless.. but the speed of wireless will make a mockery of your SSD.. wow, 500GB SSD.. !!
The TC should be relatively easy to slot into place of the AE.. it is really the same thing.. but I sure would NOT sell it all off until you get everything working.. and I would still keep the firewire drive just as a further backup.. there is nothing wrong with using a different software and then leaving the FW drive in a friend or relatives house for a rainy day.

Can't change sort settings for multiple items in iTunes 7.1

iTunes 7.1 introduces a great feature—the ability to set a separate Sort Name, Sort Artist, Sort Album, etc. This means that "Weird Al" Yankovic songs can finally appear down among the Y's instead of up at the top of every list, by changing the Sort Artist to Yankovic, Weird Al.
Unfortunately, this feature is fatally crippled in 7.1. As far as I can tell, you can only change the Sorting information on individual tracks. When you change the information for multiple tracks, the Sorting tab doesn't show up. This renders the feature all but useless.
Let's say (hypothetically) that your friend is an enormous nerd (in theory) and your friend has 139 "Weird Al" Yankovic tracks (for the purposes of this example only, of course). Instead of just selecting all these tracks at once and changing the Sort Artist to Yankovic, "Weird Al", I (I mean, he) has to retype this information for each individual track. That's crazy! Surely this must be a bug.
Core 2 Duo 20" iMac Mac OS X (10.4.8)

I just found the solution to this myself.
In a very un-Apple way, this is an undocumented feature only accessible by right- (or control-) clicking.
1. Change one track to your desired sort settings (for instance, set the Sort Artist to Yankovic, Weird Al.
2. Right-click on that track. In the contextual menu that appears, there is a new submenu called "Apply Sort Field." If you choose "Same Artist," it will apply your new sorting information to all your other tracks by "Weird Al" Yankovic (or, if you are not a huge nerd, any other artist you substitute).

Why does the tab in the settings for keynote for iOS for icloud keep flipping itself back to OFF?

I added a keynote document to icloud/iworks on my imac. No sign that it nade it to my ipad2. What i did notice is that the slider switch on the icloud settings for keynote on the ipad keeps restting itself back to OFF, despite several times setting it to on. No sign of my Keynote file making it over from my iMac. Any suggestions?

Just so we don't lose the point of the rant: is there anyway to fix or (please, please) eliminate this animation or scrolling or bouncing or whatever you'd like to call it? I have been looking for a solution for some months now and the few people who do manage to communicate their concern are never answered, or they get obscure advice on something in about:config that doesn't do squat.
SO, IS THERE A WAY TO FIX OR ELIMINATE THIS 'FEATURE?'

I think that everything that he wants to do is very doable. It would be quite a project for someone to take on for him. If it is a popular hymnbook it may well be a welcome blessing/gift of love for many others as well if made available. As I would envision the project it would require either the sacrifice of a copy of the hymnal or the availability of a loose leaf version of the hymnal, so that the individual pages could be taken apart and scanned. The scanned pages could then be assembled into a pdf document that is easily readable on many apps available for the iPad. Better still would be to research if the publishers of the hymnal have not already created an electronic version of the book in pdf format. If the publisher has not already crossed this bridge, then their permission would legally need to be secured before starting such a project of copying their compilation of hymns. Even though they may not own the rights to an old hymn which is now in the public domain, they hold the rights to the layout and composition of the printed pages of their hymnal.
The Accessibilty settings in the iPad itself is capable of enlarging text for the visually impaired, as well as providing white text on a black background.

Audio Settings for Premiere CS6

Hi, I currently run a Mac Pro with a 27 inch Apple Monitor with built in camera. The machine is also running Mountain Lion 10.8.5. Could someone give me some clarification as to why the Audio Settings for Premiere CS6 are the way they are?
Example with a Macbook Pro and an iMac when I plug in a headphone I can get the sounds from Premiere pro as well as something from youtube to the headphones. However in the case of the Mac Pro with the Apple Monitor, when the headphones are plugged in the youtube sounds come through but the Premiere sounds go through the monitor. I'm aware of the audio settings but I suspect this is working by design because of the different audio options the Mac Pro have and there is nothing broken about this.
Please advise.
Thank you.

I've always found this a bit annoying.
The intended behaviour is that if you go into Premiere's audio settings, and choose "System Default Input/Output", it should change along with the system (so that the audio comes out wherever YouTube does). In practice, I've found this to be inconsistent in pre-CC versions of Premiere (CC fixes this).
One tip that may be helpful for you in general on a Mac Pro:
1. If you don't already have the volume icon in the menu bar (by the clock), enable that in System Preferences > Sound.
2. Option-click on the icon and you'll get a quick menu of your output options

Master/Slave settings for HD and SuperDrive

i recently updated the hard drive to a 17" usb2 iMac flat panel, I upgraded the standard 80GB HD with a new maxtor 250GB disk, the problem is that the transfer rate from dvd/firewire/hd to hd are superslow.
what i don't know is the jumper settings for the two units, i used slave for the superdrive and master for the hard drive, is it possible that they go inverted?
thanks
g

I don't know if that's causing the low data rate, but Apple sets the superdrive to master and the harddrive cable select (see http://developer.apple.com/documentation/Hardware/DeveloperNotes/Macintosh_CPUs-G4/iMacNov03/index.html). I know from own tests that the 17" iMac G4 is capable of 50 MB/s for the internal HD.
