Having used a Hackintosh as my desktop for the last 10 years without issue I'm inclined to attempt the same for my laptop now that my 2013 Macbook Pro is looking a bit old. At nearly half the price it's becoming a no-brainer. Are there high-end laptops with screens comparable to Apple's retina display nowadays? I'm also assuming disk and RAM can be replaced in Dells and ThinkPads but maybe I'm mistaken?
