    This question torment me for months: should I upgrade from Mavericks to sierra with my glorious iMac 27" Late 2009?
    I've made some tweaks during years, here the info:

    Processor 3,06 GHz Intel Core 2 Duo
    Memory 16 GB 1067 MHz DDR3
    Graphics ATI Radeon HD 4670 256 MB
    Fusion Drive with Samsung MZ-7TE250BW SSD 840 EVO 250 GB + 1TB HD (this is the tweak)

    I've read that time ago the OSX will have problems with homemade Fusion Drive, is right? Can I reinstall from zero without troubles?
    I use graphic software (Ps, Flash), will speed up or lag?
    I use notes (on iCloud) is true that will delete all of them?

    All my best wishes for every answer ;)

    I'd say go for it. Make a Time Machine backup and upgrade to Sierra within the OS. Should be smooth sailing.

    OS X won't have any issues with a homemade Fusion drive.

    If you have a few hiccups, restore from TM backup.

    Disable transparency effects in Accessibility. 256 MB VRAM is very little for 27" and transparency.
