rened 20 Report post Posted May 7, 2022 1) for intel When you start eyetv In the console, you will have the following message '/Applications/EyeTV.app/Contents/Frameworks/CoreAVC.framework/Versions/A/CoreAVC' not valid for use in process: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.), it seams that frameworks have not the same signature that main app and can't be executed and video will be played without avc hardware. exec the command below in terminal: codesign --remove-signature /Applications/EyeTV.app/Contents/MacOS/EyeTV this will fix slutter, black image problems and perhaps 720p problems . 2) to install version 8528 on M1 copy from 8528.dmg to /Applications create the script below and exec it ( this will starts eyetv for 5s , remove signature, then create exe to remove arguments which crash app) #!/bin/bash /Applications/EyeTV.app/Contents/MacOS/EyeTV& sleep 5 kill % codesign --remove-signature /Applications/EyeTV.app/Contents/MacOS/EyeTV mv /Applications/EyeTV.app/Contents/MacOS/EyeTV /Applications/EyeTV.app/Contents/MacOS/eyetv.exe cat >eyetv.c <<% #include <unistd.h> int main() { char *argv[] = { NULL };; execv ("/Applications/EyeTV.app/Contents/MacOS/eyetv.exe",argv); } % gcc eyetv.c -o /Applications/EyeTV.app/Contents/MacOS/EyeTV 1 Quote Share this post Link to post Share on other sites

AppleFarmer 0 Report post Posted August 18, 2022 Thank you! I can confirm that this fixes the issues with choppy HD playback with all versions newer than 8517. I was using version 8517 and now after this fix 8528 is usable. Quote Share this post Link to post Share on other sites
