The display brightness also can't be changed. Two finger scrolling doesn't work and the function keys don't have the normal functions in OS X. Officially, the maximum Windows OS supported on MacBooks is Windows 7 x86 but I've been able to run Windows 10 圆4 with a couple glitches. Another alternative is installing Windows. Linux operating systems support the latest versions of Firefox and Chrome. Alternative solutionsĪside from trying to install a newer version of OS X on an unsupported Mac (don't try it it doesn't work very well on machines dropped with Lion), the best solution is to install an alternative operating system. Generally, software support for Lion is becoming scarce and an alternative solution will soon be necessary. However, there are a few years before that will happen. The main concern is when websites no longer support these older browsers. Though there are 'security risks' with using Lion to browse the net, I haven't had any problems. Opera is built on Chrome's Chromium webkit engine so Opera support was also cut around the same time as Chrome. The default Safari browser hasn't been updated since 2014. Chrome supported Lion until April of 2016 while Firefox supported it until August 2016. As of this writing, no major browsers support Lion.
