I keep complaining about the fact Mac OS asks me whether I want to allow chrome to access the local network with every update. I tried to dig deeper and discovered a privacy settings UI with dozens of entries written "Google Chrome" with the permission disabled. One for each time I said "No".
This is absolutely embarrassing. I wouldn't call it a bug, but a lazy and incompetent design that I thought could not happen in a Apple product.
I'll give you another example. Lately I've noticed a progress bar under the Apps icon on the dock. At first I didn't even know it was a progress bar because I use the Dock vertically - it looked like a separator - and the progress bar made no progress.
One day, the progress bar actually made progress and stayed stuck at 80%. I thought something had crashed and rebooted the machine. It stayed there. I eventually discovered by trial and error that the problem was that a running WhatsApp app prevented the WhatsApp update process to finish. Since it was always open as I used the computer, that annoying UI element stayed around forever. By closing WhatsApp, the bar unlocked and the update finished.
Pretty horrible. Is Apple learning from Microsoft?
