How I can force HiDPI on external monitor 2560x1440 to use it as virtual 1280x720 in Big Sur? RDM doesn't show any Retina resolution. I tried to generate displayproductid-xxx.plist for my monitor using a script: codeclou.github.io/Display-Override-PropertyList-File-Parser-and-Generator-with-HiDPI-Support-For-Scaled-Resolutions/ But ioreg -l | grep "DisplayProductID" ioreg -l | grep "DisplayVendorID" returns nothing. Also I tried this script: github.com/xzhih/one-key-hidpi - doesn't work, too. Note that this folder cannot be modified even when SIP is disabled: /System/Library/Displays/Contents/Resources/Overrides/

How to correctly install codesign certificates on second Mac? I have first Mac where I successfully sign and notarize my apps for macOS outside AppStore. On second Mac I downloaded existing "Developer ID Installer" and "Developer ID Application" certificates and installed in KeyChain. Also I downloaded and installed Intermediate Certificate. When I try to sign anything on second Mac I see the error: "error: The specified item could not be found in the keychain." Also I have a file "CertificateSigningRequest.certSigningRequest" saved from first Mac. No idea how to use it. What I missed in this nightmare to get it work? And keep codesigning on first Mac, too.

Hi,I have serious difficulties with offscreen rendering in Metal or macOS. I can't find any example/demo project with solely offscreen rendering without any MTKView on 2nd pass. Just rendering to a texture with copying to a bitmap in system memory.My code works strange, it returns a black picture on first run and starts to render frames only if I call rendering on timer event or on a button click. If I call rendering in a loop, it always returns a black picture.I have no problem with usual rendering with MTKView.
