The app hangs when changing fan control

[bladedthoth]

Ever since I had to replace the hard drive in my iMac (27-inch, Mid 2010 - iMac11,3), I've had the dreaded Mac fan issue. Even though I matched model exactly, still had the fan issue. I had tried a lot of other fan apps which never seemed to do anything for the HDD Fan speed. I found your program and was tickled pink that it worked so well.

About 3 months ago, I reinstalled my Mac to get Yosemite to work properly. I was content on Macs Fan Control 1.2.x. It wasn't until the update came along to 1.3.0 that I started having problems.

First reboot after installing 1.3.0, the icon shows up for MFC, but if you mouse over it, you get the beachball of doom. After about 5 minutes, my Mac's HDD fan spins up full speed and never stops (Until I reset my PRAM and my SMC, which gives me another 5 minutes.)

I've done a bunch of digging, and the only preference file I can find is in PreferencesPane. Even if I remove it, force-quit MFC and relaunch, it still hangs. After a reboot, MFC will come back up but does not control my HDD fan. So if I go in and manually set it to anything besides the default for the HDD fan, the app window promptly locks up. Rinse, repeat.

I do not have any app that reads SMART besides the built-in Disk Utility in OS X. Upon a launch and before a trigger of the app, it does read all the fan states in the system successfully; It is not until I try to change the HDD fan speed setting that it does anything (Heck, I can change the others with no problem, just for testing, but all I need is the HDD fan.)

I love this app and would really like it to work again.

Thanks in advance for your reply!

What about crash reports? Please share them

[bladedthoth]

No crash reports. If I don't force quit it, it never terminates. No crash log. Just beachball of doom.

*bump* Any ideas?

[Steven]

bladedthoth
I don't get it. The app simply works in background and you don't see it and have to force quit. Right?
Then how do you managed to take the screenshot?

[bladedthoth]

As mentioned above, as soon as I change the hard drive setting, the app locks up. The windows stays visible but goes 'Not Responding'. If I reboot, it launches, the icon shows up in the menubar, but if you mouse over it, beachball. Try to click on it, it does nothing. If I force quit it through the Activity Monitor and try to restart the app, it does same thing.

If I force quit it, go in and delete the Preference file, and try to reopen it before reboot, it just hangs. You check the folder, and the preference file is there.

To get it to relaunch so I could provide screenshots, I have to delete the Preference file, reboot the computer, relaunch Macs Fan Control and it will come up.

It worked with 1.2.x version; As soon as I upgraded to 1.3.0, this started it. I've tried deleting the preference file and 1.3.0 MFC, rebooting and then reinstalling the older 1.2.x version of Macs Fan Control, but that doesn't work.

Question; Besides in ~/Library/Preferences, does MFC save anything elsewhere that I could try deleting?

[Steven]

bladedthoth
That's a very strange (and sad) story No, MFC stores its preferences in a single file.

Can you record a video (after cleared preferences) to see the hang problem?
Please also enable log in Preferences.

[bladedthoth]

As soon as I turned the log on, after wiping the Pref file and rebooting, it beachballs on startup now. Where is the log stored?

Attached is the video. Please note that the video doesn't show the beachball, but it happens as soon as I click 'Ok'

[Steven]

bladedthoth
The log is stored on the desktop. Correct way of clearing preferences is

Code: Select all

#!/bin/bash

killall MacsFanControl
rm ~/Library/Preferences/com.crystalidea.macsfancontrol.plist
killall -u `id -u -n` cfprefsd

Does it hang if you simply set some constant value? (not sensor-based).

[bladedthoth]

Even by me just setting the 'Enable Logging' preference, it locks up on the restart (Not immediately.)

It does hang on a constant RPM value as well.

It actually hangs with setting the ODD and CPU to constant or sensor as well. It almost seems like as soon as the preference file is made, it goes under unless it is the default settings file (Nothing changed.)

Edit: Your command-line thing at least prevents me needing to reboot each time to test.

Do you have a log file (located on your desktop)

This is why I NEVER update any of my programs/apps/software without backing up the previous version first.

Had a backup. When I rolled back to it, it still had problems.

Developers ALWAYS like to break programs with horrible updates. I keep getting a popup to update my macs fan control, very rude and intrusive, but I refuse to update. I learned my lesson with apple and the iphone NEVER to update anything unless you truly need something that is new.

Oh yes, that's right. He INTENTIONALLY broke this update. /s I'm here not only to work through my issue, but help him potentially find a bug that may have been INADVERTANTLY added. I will agree, the pop up nag to update with no way to dismiss indefinitely is a bit of a headache and why I finally did it (Figured if it was nagging, it had to be for a good reason.)

If everything works fine, there is no need to update. If it's not broke, don't fix it.

Unfortunately, I don't see a single thing that helps the situation here, and instead you are using this as your personal platform to complain. If you want to complain, start your own thread, and leave mine to support. Thanks.

[bladedthoth]

Hey Steven; Been a couple days. Any thoughts?

[Steven]

bladedthoth
Hey. Sorry for the late reply.
1. Has the app ever worked fine on this mac?
2. Try to delete this file and tell me if the app still hangs: Macs Fan Control.app\Contents\Resources\smc-write

[bladedthoth]

#1: Yes. Worked fine prior to a reinstall of OS X. Worked fine after a reinstall. Wasn't until I installed the update 1.3.0 that it stopped working.
- I reinstalled because Yosemite was running so slow for me. Reinstall helped with speed.

#2: Deleted the smc-write file from inside the .app. Still hangs on change.

[Steven]

bladedthoth, would you test the special debug version with verbose logging/messages?

[bladedthoth]

Sure! I'd love to.

[Steven]

bladedthoth
http://www.crystalidea.com/downloads/ma ... ol_dbg.zip
This version will product exactly 7 messages (numerated) after you try to modify fan speed.
If the app will hang, the will be less messages.

PS. Not log messages, but directly in the app window.
