Please tell me is it worth buying?

Your MacBook Pro has two graphics cards: the integrated Intel GPU and the dedicated AMD Radeon Pro 5500M. By default, macOS automatically switches between them to save power, but this can cause games like Minecraft to run on the weaker integrated GPU instead of the powerful AMD card. This is why you’re seeing poor performance and glitches, even with OptiFine and shaders like Sildur’s. To fix this, you need to turn off Automatic Graphics Switching in your Mac’s Battery settings this forces your MacBook to always use the dedicated Radeon GPU when plugged in. Once that’s done, use lighter shader versions, match them with the correct OptiFine version, lower some video settings, and make sure you’re using a recent Java version for the best performance. These steps should help Minecraft run much smoother and make your shaders look better without bugs.

Through to the Semi's yet again... to face Sinnerman! Today's win could very well be his final win on Center Court at the Wimbledon if this year marks his final appearance at the SW19. Defeating Sinner in the SF next will be a humongous task!

Me too

Why would you want serious tone in Superman movie? Superman comics are not serious brooding like Batman. That idiot Snyder made Superman serious and negative like Batman and made everyone think Superman is like Batman.
