Hi. I'm trying to learn macOS app development. i'm trying to run unix commands: func execute(_ command: String) throws -> String { let process = Process() let pipe = Pipe() process.executableURL = URL(fileURLWithPath: "/bin/bash") process.arguments = ["-c", command] process.standardOutput = pipe // process.standardError try process.run() process.waitUntilExit() guard let data = try pipe.fileHandleForReading.readToEnd() else { throw CommandError.readError } guard let output = String(data: data, encoding: .utf8) else { throw CommandError.invalidData } process.waitUntilExit() guard process.terminationStatus == 0 else { throw CommandError.commandFailed(output) } return output } when try to run "pgrep" in sandbox mode ON, i get: sysmon request failed with error: sysmond service not found error. if i turn it off it works. i don't know what to do. anyone can help me out?
