Over time, I learned quite a few solutions, tricks, hacks, fixes and undocumented features of Mac OS X and the hardware that goes with it. You might already know that a relatively old Mac Pro 2008 becomes a whole lot faster when the hard disk or even the software RAID is replaced with an SSD, but did you also know that it is pointless to use a state of the art SATA III SSD? Or that you can add a USB 3 controller card for less than a decent USB 3 memory stick costs? Or how to print borderless at 100%?
Quite some of this neatly arranged information can be found online in one form or another, but it will take a lot more time to find it in the lengthy forum threads, official documentation and youTube videos.
