Mac Mini 2012 video blinking out

I just got my 2012 Mac Mini yesterday (mid range model) and have already noticed three instances where the video would blink out for about a half second, and then come right back. This happend twice already when I'm connected to a Apple 23 inch LCD monitor via the included HDMI-DVI adapter and once when I'm connected via HDMI to my Samsung LCD TV. Anyone else noticing this happening on their Mac Minis? Thanks.

First they did a firmware update, that solved the problem for some, not me


Then came the 10.8.3 release - that solved my blinking problem (approx every 10 secs!), but not for everyone


Strange issue!


Biggest issue for me? I still have an open support case - and they haven't contacted me for 3 months! I had a useless Mac for 4 months - it was their fault. I also has a bad support experience, including being told at a Genius Bar that the problem was my tv


I want compensation

Well. Had the blinking issue before, but the EFI update took care of most of it. And now with 10.8.3 I have no HDMI/monitor problems at all – even though I switch between monitor, tv and home cinema projector, and go through two receivers, sometimes using pass-thru, sometimes not… I mean, my set-up is made for triggering HDMI conflicts all the time! 🙂


I understand that there are problems still not being solved, but these must be limited to certain set-ups/circumstances/monitor models. If you ask me, the 2012 Mac Mini is pretty perfect. I think this should be said. Most people have no problem with it.

I was planning on buying a Dell Ultrasharp U2312HM, initially using the HDMI-to-DVI converter, and adding a miniDP to DP cable later. If Apple can promise that I won't have any problems with this setup then I'll buy it. But they can't. And refund laws in the UK are pretty awful. If you buy online you get 7 working days to return for a refund. If you buy in-store, you get NO refund rights. It's rather frustrating because it does look like it would be the ideal photo editing machine for me, but in all honesty I can't take the chance.

For the record, after updating to 10.8.3, the sub-second flashes several times a day continue unabated. Looks like I'll have these for the life of the computer and/or monitors I'm using. The same monitors that have never had a problem with any other computer, including years on my Early 2008 MacBook.


While I'm happy that the problems are fixed for many, I'm not happy about being in the group that Apple has abandoned.


I will never buy another computer that uses video memory shared with the CPU.
