I know this is not about colour but it is a Mac forum... I (bravely) upgraded to the new Mac OS X (El Capitan). It immediately disabled my USB hub which meant I had to reconfigure my connected devices in order to connect one 8gb USB flash drive to my Mac Mini 1TB Fusion Drive where the sockets are inconveniently located out of sight at the back of the machine and so close together you have to pick it up to get them in. But it looks nice. I then opened the Disk Utility which I discovered had been redesigned in order to format the USB drive to give to someone with a PC. The new Disk Utility looks nice too however, after formatting the flash drive it was unreadable in any PC. I formatted the same USB drive in a PC as FAT 32. It only allowed me to create a single partition of 200mb. When I plug it back into the Mac I have two partitions: one with the original data that should have been erased when formatted in the PC, and new files that I copied from the PC for testing. I repeated the task using ExFat. Same result. I did it again using a 4gb USB flash drive. Same result: Two partitions, no data erased after formatting on the PC (Windows 7). I am glad to have discovered these idiosyncrasies before performing the same task on one of my external hard drives or relying on a my USB ports for a chain of printers. Before someone replies with an obvious and simple explanation resulting from something I am doing wrong I would like to get in first. I appreciate Apple has set the benchmark in terms of style but it is these 'little things' that take away the gloss. When will they learn that, in a world of practical necessity, form is nothing without function? I like the style but I need the substance. Regards, Mark Stegman
