Installed both the updates – when it comes to OS X a lot of drivers and frameworks have been touched. The GPU driver for the Broadwell based GPU has been updated, Wifi driver has been updated along with the 802.11 stack because it appears that some of the issue people have faced crosses the divide between the driver itself and the stack on which the whole wireless networking operates. I jumped down into the terminal and it also appears that discoveryd service has been updated as well which will hopefully put to rest some of the complaints there have been regarding bugginess in Apple’s networking stack. When it comes to iOS 8.3 the first thing I noticed is that the modem firmware has been updated from 1.0.4 to 2.23.03, I’m unsure what that means but hopefully with some use whilst at work I’ll see whether it translates into better reception, longer battery life etc. All in all I’m pretty happy with how things are doing and will give a bit of an update after work tomorrow/today.
