I want to download Xcode that I deleted again. But when I open App Store and search for Xcode the download button is grey

When I downloaded it before I did it through App Store but now that doesn’t work because of that the button is grey. Have tried to download Xcode through developer.apple but there it says that I don’t have enough storage which I clearly do because I got 16 GB free. HELP

factory settings MacBook Pro 13 inch 2011 – grey screen stop sign

Because I am selling my old MacBook Pro (13-inch, 2011) and, for this reason, restore it to the factory settings.

I have followed the steps for this. First the discs were erased which only partially succeeded. In the next step “reinstall macOS” I now get a gray screen and I can’t get out (even after I turned off the laptop). Hellup.enter image description here

Stuck pixel only on dark colors like black and grey

So my Asus VP247H-P show a red pixel on the display only when it’s dark colors supposed to be there. When it’s lighter colors like white, blue, green, pink, violet, etc it works. What can I do?? I tried JScreenFix but it doesn’t help. If I can’t find any safe solutions, I will just send it back to Asus for repair since I still have the guarantee. Thanks for your help!
