    Hi There,

    Here’s my config. :
    iMac (21.5-inch, Late 2012)
    Processor 3,1 GHz Intel Core i7
    Memory 16 GB 1600 MHz DDR3
    Graphics NVIDIA GeForce GT 650M 512 MB

    macOS Sierra version 10.12.2 (16C67)

    Since macOS Sierra beta last summer, lots of issues with my iMac.

    Here are the problems :

    1. macOS keeps crashing on a regular basis, either during a session or a sleep.
    See the latest crash’ report attached.

    2. Safari and Safari Technology Preview keeps crashing as well : "Web content quit unexpectedly”.
    See latest report attached.

    3. Mission Control doesn't keep its settings. After each crash or manual reboot, all my Spaces are gone but the default one.

    Any idea ?

    Thanks for your kind help !

    Crashing that frequently means you have a serious problem.
    Have you downloaded and run EtreCheck? Do you have a back up of your drive?

    In the menu bar, choose Apple menu > Restart. As your Mac restarts, hold down the Command and R keys until the macOS Utilities window appears. (you need to be connected to the internet for this)
    Select Disk Utility, then click Continue. Select your startup disk on the left, then click on First Aid.
    Let Disk Utility run and fix the errors it finds.
    When done, quit Disk Utility and select Reinstall Mac OS. Continue to follow the on line instructions.

    With a fresh install, you should see an improvement.
