If you want 5k then you really should do it Apple's way with the OS du jour. Because Apple hardware is fixed and what it is not, particularly GPU hardware and drivers, and what users do on it is also fixed under the hood improvements, unawesome as they are, also are difficult to appreciate in newer versions of OSX but are there. Apple defines legacy as anything they sold you an hour ago.īecause only the icons change the GUI experience in OSX is unchanged since Snow Leopard or earlier. However if you research the facts instead of the opinions you might find that the programs and peripherals you cherish will run on High Sierra, as just about anything should although Apple can be arbitrarily obnoxious about legacy support compared to Microsoft. Some of us horde these things for no apparent reason and some do not, like old Windows installation media. You would need to have the installation media for an older OS which Apple deletes from its servers with each new OS release or upgrade. You can follow Bent's advice but I think you would be wrong.
