Having become totally disgusted with numerous problems in Windows 8.1, and having had a good experience with the last three iPads I've owned, and my iPhone, I thought I'd make the switch to a totally Apple environment.
I purchased a mac mini 2014, 8gb version and have regretted it ever since. It just WILL NOT work properly with my Asus monitor. Unless I boot it with a PRAM reset every time! (Whereupon it works without issue via thunderbolt to display port). I did updates, SMC resets, PRAM resets, safe modes etc.etc. NOTHING WORKED. The HDMI connection cable had similar problems (and even more as it wouldn't respond properly after sleeping) Having checked the Apple forums, you will find it is UTTERLY creaking under the weight of people with countless problems to do with wake/sleep/hdmi/thunderbolt/laptop display related issues! Most of the users had no problems with this under the previous version of OS X. The release of 10.10.1 made no difference to most of these people, myself included!! Yet when you search the web, it's not even MENTIONED in articles that claim to list the 10 MOST COMMON bugs in Yosemite!!!
I find it almost INCOMPREHENSIBLE, that after TWO MONTHS, huge amounts of people can barely get their MONITORS to work! For a vertically integrated company that makes BOTH the hardware and software, and charges a RIDICULOUS PREMIUM for inferior hardware, on the grounds that it is EASY to use, reliable and offers a superior user experience, I find this utterly APPALLING.
Their beta testing program clearly does NOT WORK PROPERLY. Hopefully, 10.10.2 might mean I can actually shutdown and re-boot my two month old mac without resetting PRAM each time!! That's if they even bother with this, given the amount of OTHER bugs they have to fix. This is NOT what I was expecting from APPLE. VERY disappointed :-(
