Encoding PAL videos to mp4 with ffmpeg goes extremely slow (around 1 second of footage per second, while for comparison my MacBook Air 2014 manages 5 seconds per second)Īpple said "80% of the times doing a full format and reinstall solves problems like this".The process VTDecoderXPCService sometimes takes several hundred percent while playing video.Indicated CPU usage in Activity Monitor seems to increase proportionately with CPU temperature (and how long the machine has been on), but this is somewhat unsure.The iMac (and previous Minis) never got anywhere near as hot. The machine gets extremely hot, at most CPU temperature 101 degrees according to my temperature utility.Playing mp4 movies in both QuickTime, VLC and in webpages in Safari works fine for some time, but after a while starts lagging.I used to have a iMac 2006 earlier, and to my surprise the Mini 2011 seems to be much, much slower. And then, of course, a restart to make sure what QuickLook Satellite hasn't crashed or is stuck trying to render some video file or something.I just bought a Mac Mini (mid 2011) secondhand with the following specifications: I'd do everything I can to reduce the number of Finder windows, file icons, previews and other things that are visible or hidden behind other windows. Maybe also if you have a cluttered desktop with lots of icons. I'd imagine that icon and especially Cover Flow view use Quicklook Satellite a lot, so you may want to avoid them. Do you have a lot of Finder windows open? Or a lot of tabs in a Finder window? If you are using Column View, maybe choose View, Hide Preview. It can take up a lot of processor power when you have a large graphic or video selected. It can even open many Word documents.Īs for "QuickLook Satellite," that is what will show you a preview of whatever you have selected in the Finder.
If you just need to write some text or view a document for reading, try TextEdit. TextEdit will be a lot less demanding on your CPU and GPU than Word. One thing you may want to try if you really want to stick it out with your old mini is to try using lightweight apps like Numbers, Pages and even TextEdit when you can. Word and Excel are very pro-level apps that can be pretty demanding. If performance is what you want, then expecting it out of a Mac mini is like expecting it out of a low-priced economy car. 8GB of RAM is only one thing, the GPU memory is important too. Mac minis not only have budget processors, but also budget GPU (graphics chips). You are talking about an 8-year-old Mac that was one of the slowest of the line even when it came out 8 years ago.
