should I upgrade to high sierrathick
Hi,
I was trying to enter a question but I'm so thick that it didn't appear to allow me? Therefore, while here, should I upgrade from Yosemite 10.10.5 to high sierra? But, real dilemma is that I put a wee disc in drive for instruction manual for MP3 but it didn't show up & now is stuck in the drive? Any help please!?
MacBook, Yosemite 10.10.5
