Preferences and Sensors gone after power cycle/ unplugging

[clemens2]

Hello.

I recently built a SSD into my iMac 27inch 2011. I placed it behind the Optical drive and attached it to the 3rd SATA connection.
When I booted from the SSD first time the fans were going crazy.
Anyway this is a known issue. I'm pretty sure that I did not damage anything.
Macs Fan Control helped me to solve this annoyance - THANKS!

But there is one thing that is keeping me puzzled.
I have MFC as startup item. In the beginning after shutting down and unplugging my iMac ( I do that overnight) the fans raved up again. Having a look at the preferences I saw that almost all sensors where gone and the fan- preferences where switched back to 'Auto'.
Restarting MFC resolved the issue.

Have a look at the logs before and after restarting MFC.

Meanwhile this behaviour of MFC persists, but strangely enough the fans stay quiet and at normal speed.
So there is not really a problem anymore, right?

I really would like to know what happened and what I can do to make the fan- preferences and sensors make 'stick'.
Thanks in advance.

Do you have any other startup apps that can read sensors?

Hello Steven.

No, there are no startup items that read sensors.
After I had this issue I installed 'Hardware Monitor' to see if other programs do read those missing sensors and HM does see and read them. Does not seem to be a hardware issue.

Looks like MFC is not able to read sensors just right after boot. If you run it little later - it's fine, right?

[clemens2]

That is right. Like I said using it as a startup item, right after boot MFC cannot read the sensors I' ve set earlier. Therefore it switches back into 'Auto' mode.
Restarting MFC gives me back every functionality. But I have to reassign the sensors and set the temperatures.

I just would like to have some peace of mind never to experience those roaring fans again.

1. Please post technical information (from Preferences/Diagnostics) when sensors are missing.
2. Please try this version for some time (and post feedback afterwards)?

Hello Steven,

Thanks for the version you provided. It really seems to do the trick.
Sensors and control- configurations are available after reboot/ unplugging.
Thanks a lot.
What did you do, can you elaborate what was the problem?

greetings,

Clemens

[Steven]

I'd like to have tech info from 1.1.2 version (current stable) when sensors are missing...

What did you do, can you elaborate what was the problem?

I just removed zero check when checking sensors on the start. Not sure if it's a good idea to put this change into general release

Thanks. Maybe a better option is to run MFC after boot with a small delay (passed with command line for example).

[clemens2]

Steven,

Thanks for your efforts and good software.
I made an Automator file to delay startup of MFC.

The question that remains to me is wether there is an issue with my iMac or has MFC developed a bit further to deal with such occasions?

greetings

Clemens

[Steven]

I think it's an issue with your iMac. But it's definetely not a problem, just a particularity

[clemens2]

Hi Steven,

One last thing before everything runs like I would like to:
MFC is starting with a delay. Thats good.
The main window pops up instead of staying minimised as menu item.

Can you please point me the right direction how to script something like that:
Launch application and keep it minimised.
Or 'hide to menu bar'- script like the button of your app does.

Thanks a lot.

[Steven]

Here you go:

[clemens2]

Thanks Steven.

Unfortunately I failed to use the '/minimized'- parameter.
That is what I tried:

Code: Select all

open /Applications/Macs\ Fan\ Control.app /minimized

Code: Select all

open /Applications/Macs\ Fan\ Control.app -minimized

Would you be so kind to tell me the proper command?

Thanks.

[Steven]

clemens2

Code: Select all

/Applications/Macs\ Fan\ Control.app/Contents/MacOS/MacsFanControl /minimized

[clemens2]

Hi Steve.

Still not working. To get it straight we are talking about using this command in Terminal, right?

Code: Select all

open /Applications/Macs\ Fan\ Control.app/Contents/MacOS/MacsFanControl /minimized

I get the response

Code: Select all

The file /minimized does not exist.

Which makes sense to me because '/' is used to describe a path.
Possible parameters are:

Code: Select all

Usage: open [-e] [-t] [-f] [-W] [-R] [-n] [-g] [-h] [-b <bundle identifier>] [-a <application>] [filenames] [--args arguments]

Update: I get it, I do not have to use 'open'. Just the part

Code: Select all

/Applications/Macs\ Fan\ Control.app/Contents/MacOS/MacsFanControl /minimized

Works!

Steven, thank you so much for your help and patience.
That is a great piece of software you have written. Keep on the good work!



thx
