I’ve now sold my Probook 450 g6 as I couldn’t get OSX working properly and the performance was terrible under load in real world applications. When rendering on i5 it easily hit the 15 power limit and I couldn’t undervolt or anything to get the turbo higher leading to 1.6ghz all core. My dual core mid 2014 MacBook Pro with its 28w dual 4287u gave me double performance in davinci resolve renders.
I’d love to have been able to keep my hp as it was way quicker in web browsing but sustained loads and rendering isn’t suited to this laptop as the chip is so gimped even plugged in with power and enough cooling.
