Yosemite issues maybe

[Dryside]

Has anyone had any issues with WeatherCat and odd video issues.   I do know that the USB driver was not compatible completely with Yosemite.  They have just came out with a new version.  Maybe not be on website quite yet.  This is what one tech person told me about it because I thought this might me my issue.  "However, functionally this driver is the same as the previous version, with the only exception being that this driver has been signed and thus no longer requires enabling unsigned drivers to be installed, which had been required in light of the changes in OS X 10.10"

My issue has been my iMac restarting without warning and repeating that on its own for 3 to 4 times before things seem to go back to normal.   Lots of strange screens some times.   Each time it restarted it would start two copies of WeatherCat.  I do have it in my startup list.  To make a long story short, I think, I tried to uninstall the USB driver but none of the files showed up where I was told they should be and WeatherCat was working.  I was given the new version and installed it and driver showed up in right place but still had graphic issues after 2 days.  During these errors I several time got messages about Graphic error.
I then uninstalled the new version and WeatherCat still kept working. 

I then discovered to driver files in the system/library/extensions file that had old date so assumed they were from the old driver.  I removed those and then WeatherCat wouldn't work as is shouldn't.  I reinstalled the 10.10 driver and so far all is working correctly. 

I am just guessing but I think that installing the old driver on Yosemite put the driver in the wrong place which caused the problems.  We will see.

During this time I thought my computer was the problem and so took into Apple and they tested it for 4 days and found no issues.

I will get back if I still have issues and if not maybe this will help someone else.

Dear Ken and WeatherCat Yosemite "residents . . . "

This may not apply to your computer, but just in case.  I've been having problems with memory leaks on my Mac since upgrading to Yosemite and this thread has a link to an Apple Support Forum "recipe" to get rid of those leaks:

http://athena.trixology.com/index.php?topic=1478.0

I tried to do it once, but it is a very protracted procedure taking something like 2 hours.  The last step is the critical one: resetting the PRAM.  Alas, according to the initial posting, unless you do everything before that, resetting the PRAM won't work.  I'm still suffering from memory leaks, so I need to try that recipe once more.  I just haven't found 2 free hours to go though all that.

Good luck with your Mac!

Cheers, Edouard

I haven't noticed any memory leaks but I will pay a little more attention to that.  Thanks for the link.  Since my first post I am still running OK.

I didn't any more than write the last post when my computer quit again.   I got it running again and then it quit about 10 minutes in to use.

The only reason I think that WeatherCat may be involve is the fact that my other computer had no issues but as a few little ones since I installed WeatherCat.  No problems before that.

I am not sure about memory leak as the second time in crashed it din't have time to have a memory leak and I was looking at my use just before quit and memory use was only about half the memory I have.

Does anyone know how far back Weather can will work in OS X.  I have an older computer that runs I think 10.7 so thinking of trying WeatherCat on it and removing from my iMac and see what happens.

From your initial description, it does seem like the same video card issue I went through with my 2008 iMac. Many of the iMacs of that period have this issue. If yours is of the same year or has an Nvidia graphics card, be suspicious.

One way to test it is to run a graphics intensive application while monitoring the internal temperatures with a program called Temperature Monitor. With mine, even after Apple installed a new graphics card of the same type, a program like Mojang's Minecraft causes the temperature of the GC to go to 160? F pretty quickly.

Unfortunately machine restarts are normally one of two things - firstly a driver issue (they live in kernel space so when they crash, they take out the whole machine) or secondly a hardware issue.

If you have access to diagnostics tools such as TechToolPro, an extended run can sometimes pin-point the issue.

[Dryside]

I have a late 2012 27" iMac.  Apple did a very long test on the graphics and found no issues. 

I followed the directions from the link for memory leaks and within an hour after doing that the my computer quit again.  I just goes to a color screen,  usually light blue or white and stays that way for up to 15 or 20 minutes and sometime much shorter and then restarts.  There is no question that Safari has a memory leak.  It will grow up to as large as 4 or 5 GB but it wouldn't have had time to do that when this last quit occurred.  What I am noticing is that WeatherCat is the larges user of my CPU most of the time.  I changes from 20 to 45 % of the CPU usage.  WindowServer is the other top user at around 23%.  There is not a lot of CPU usage total going on.  90% is idle so may not be a big deal

With respect to WCDev comment on driver that is why I suspect the Silicon Lab driver is the issue.  I am going to try and run WeatherCat off another computer and see what happens to my iMac with the driver uninstalled and WeatherCat not running.

With as much talk on the internet about the issues with Yosemite I think it is somehow related to this. 

[Dryside]

Well I think I now know the issue.  It is the combination of Yosemite, WeatherCat and the Silicone Lab Driver.  I quit using WeatherCat on my iMac that kept quitting and and for 4 days now have had no crashes.  I put WeatherCat on an old MacBook Pro running OS X 10.7.5 and it has run during that time with no issues.  Yosemite is the key factor hear but still don't know if Yosemite itself is the issue or either WeatherCat and or the driver don't work well with Yosemite. 

I am curious to know if others are having issues like this?  I am assuming maybe not since no one has indicated such on this thread.

The only think I have not done is completely erase my hard drive and reinstall Yosemite from scratch.  If others don't have this issue this might clean up some issue that is particular to my Yosemite installation.  Can't event think about trying that  until next year.  To big a job for what time I have.

Hope some others can respond with the fact they they are running things just fine with this setup or not.

I am running fine with latest OS (10.10.x) and WeatherCat 2.02. My system has not crashed, but I do use IP to connect to Davis station not a direct connection to SL driver.

No problems here.

Hi dryside
 I was having similar problem after upgrading to Yosemite and had 10.10.1 I called Apple Care and they ran the online diagnostics and could not find anything and they had me take it to the Apple Store and have them test it and they said there was no problem with the iMac but I needed to do a clean install of the iMac and reinstall Yosemite 10.10 and then upgrade to 10.10.1  I really didn't want to because of the time it takes to do it and reinstall everything but I did and it fixed the problem and it has ran now for 2 weeks with no problem


cheers

Dear Dryside and WeatherCat troubleshooters,

Well I think I now know the issue.  It is the combination of Yosemite, WeatherCat and the Silicone Lab Driver.

I'm not having driver problems, but I am having lots of other problems with Yosemite.  I'm fairly sure what happened is that iOS 8 team had less trouble implementing their upgrades than the OS X team.  Apple needed iOS 8 for the iPhone 6 so . . . . they let Yosemite out before it was really ready.

You may have no choice but to do a clean install, but you might post a question on the Apple Support Forum.  That's a much larger population and they might have an idea.  If you can limp along, it might be best to wait until after the first.  People are extremely preoccupied with da' holidaze . . . . .

  . . . . To be perfectly precise, they are stark, raving, crazy!!! . . .

Cheers, Edouard

A clean install of Yosemite appears to have solved most of the issues I was having. I had tried to do an upgrade first, but had issues with iTunes and had to do a clean install to fix that. It's a major pain to install clean but its a better solution in the long run.

[Dryside]

Thanks everyone for your comments.  After posting the last time by computer crashed again about 2 hours later.  You have all confirmed my need to do a clean install of Yosemite.  I just now need to find the time.

Thanks.
Ken
