Macbook Pro freezing



  • Hey guys,
    I recently got f.lux on my mac (MacBook Pro Retina, 13-inch, Early 2015) and I absolutely loved it.
    However, since I installed it my computer froze about three times this week, it happens this way: it freezes for a couple of seconds and then it sort of shuts down (the haptic feedback function on the trackpad stops working, as in when the computer is turned off), the screen freezes, but if there was music playing or anything it would just keep on playing. & the only way to restore control is to shut it down using the power button, as nothing else responds.

    Has anyone had a similar issue? If so, what would be the fix? I removed flux temporarily to see if the problem still appears, and so far so good.

    Cheers! :)

    Can you tell me which OS version?



  • OS X El Capitan 10.11.4



  • @lorna Hi I have exactly the same problem on El Capitan and Macbook Pro - it is freezing and freezin is gone after stopping f.lux. No CPU load, just freezing. Weird is this behavior started few days ago.

    Thanks all - if you are encountering this issue please post your OS version, hardware info and version of f.lux. I am guessing there's some new driver incompatibility. Hope to have more information soon.

    OS version, hardware info and version of f.lux.

    OS version - 10.11.4 (15E65)

    Having the same issue as everyone else - It's been freezing about once every 3 days for the past few weeks (ever since using f.lux (which I love and do not want to uninstall)

    @owayssk thank you very much for this note - it sounds like 10.11.5 fixes a good number of issues, here's hoping it clears this one too...



  • I have a Macbook Pro 13" mid 2010, running sierra 10.12.3. I had mayor crashes, did all resets possible, erased my harddrive and clean installed, replaced my RAM.. In the end I thought it was my logic board, until I suddenly realised my mac started crashing again after my clean install only after I reinstalled f.lux. I am not too sure yet, but my mac has now been on for 2 hours since I uninstalled f.lux, while before my mac would crash rght after starting up..



  • MacBook Pro 15-inch, Mid 2010 (AKA MacBookPro6,2) with 10.11.6 with frequent GPU Panic after waking up. Fixed after removing the f.lux from startup items + not using it any more.

    *** Panic Report ***
    panic(cpu 0 caller 0xffffff7f8bac8bd5): "GPU Panic: [<None>] 3 3 7f 0 0 0 0 3 : NVRM[0/1:0:0]: Read Error 0x00000100: CFG 0xffffffff 0xffffffff 0xffffffff, BAR0 0xd2000000 0xffffff91252b9000 0x0a5480a2, D0, P2/4\n"@/Library/Caches/com.apple.xbs/Sources/AppleGraphicsControl/AppleGraphicsControl-3.12.9/src/AppleMuxControl/kext/GPUPanic.cpp:127



  • Had this same problem this week running OS X version 10.10.5 (Yosemite) on MacBook Pro (15-inch, Mid 2010), 2.4 GHz Intel Core i5, 8 GB 1067 MHz DDR3 with Intel HD Graphics 288 MB.

    Installing Flux caused immediate problems - Frequent crashing when starting applications, freezing, trackpad failure, panic on startup, display failure (static), and something else terrifying that I've never experienced before - 3 tones of death leading to immediate shutdown! Left my machine almost completely useless.

    Removing Flux did not solve the problem. Even searching for Flux in Spotlight would cause the computer to freeze. Finally I found this post and realized that there was a Flux startup item that was still opening automatically every time I rebooted. Removed that and restarted and everything seems to be back to normal for now. Phew! Gonna stick with my computer glasses.



  • I spoke too soon. Still crashing :(
