    Hi all..

    Connecting to a Mac mini running 10.10.5 over WI-fi using third-party router (Billion 7800NL)

    I was getting graphics artifices (black stripes tailing mouse pointer), an since this doesn't display over HDMI physically connect, it pointed to a wi-fi issue, also it sometimes needed to "reconnect" shortly after and connection was lost.

    However, i've now just set up a second account, and have not seen this before. (Attached)

    Apart from the graphic artifacts again, the system preferences is totally messed up. SO it the "Date/Time" preference pane as well.

    This messed up pane only happens on a second account, not the first one... and i can temporarily solve the issue by connecting an HDMI cable to the mini, and accessing it locally, or remotly as long as i stay logged in.

    If i logout, then back in remotely, i get the same issue.

    Does this all point to a third party router ? However, it it was die to this, why would the first account be ok always ?

    Interesting enough, just booting into safe mode on the mac mini solved this issue...

    No idea why. I didn't even do run anything.

    Yeah I've seen similar, if you have no display connected to the Mac Mini the graphics card won't turn on, you can get an adapter which you can plug into the HDMI port which tricks the Mac mini into thinking there is a display attached and will fix your issue... They are called "CompuLab HDMI Plug with Remote Desktop Access" have a look on Amazon/Ebay etc should be around £20-£30.
