Friends who are new to macOS or running the App after updating a certain system version will be prompted with the message [xxx is damaged]，Can't open，You should move it to the Trash Solution]、【Cannot open xxx，Because it comes from an unidentified developer]，【Cannot open xxxx，Because Apple can't check whether it contains malware] and other tips，Below I will teach you how to fix it。 Several common errors: xxx is damaged，Can't open，You should move it to the Trash Solution Can't open xxx，Can't open xxxx because it comes from an unidentified developer，Because Apple cannot check whether it contains malware, it will prompt a loading failure during installation! Why does it happen? This is a problem with new security mechanisms enabled in macOS。 By default, Apple only allows the installation of apps from its own [App Store].，If you want to install third-party applications，Then you need to go to [System Preferences -> Security & Privacy -> Select the [App Store and Recognized Developers] option in General。Approved developers need to purchase Apple’s enterprise certificate to sign their applications.，Then submit it to Apple for review，This is very unrealistic for cracking applications，Because cracking the application will definitely modify the application's files, causing the signature to become invalid and the running display will be "Corrupted"。In addition, some open source free applications have no income (it is too difficult for users to actively reward)，Therefore, developers generally do not purchase certificate signatures.。 The solution is to enable the [Any Source] option.，However, macOS hides this setting by default.，The user needs to manually execute the command line code through the terminal to enable it.。 Let’s teach you how to use command line code to open any hidden source options.。 To open any source (primary) first open System Preferences -> Security & Privacy -> General tab，Check if the Any source option is enabled。 If this option is not available，Copy the following command：...

LuLu is an open source firewall tool for macOS。Can block outgoing network connections for any app，until you give us your permission。While LuLu is designed to detect malware generally by flagging unauthorized network connections，But it can also be used to prevent macOS components or third-party applications from transmitting information to remote servers。 feature 100% Free no ads，no time trial，No missing features。 it doesn't track、Spy or spy on you - because that's just pure evil! The full source code for open source LuLu is available on GitHub。This transparency allows anyone to audit their code，or understand exactly what's going on。 Protection LuLu is designed to alert you when unauthorized network connections are attempted。therefore，It can often detect malware，or to block legitimate applications that may transmit private data to remote servers。 Simple "do one thing"，Get it done! ” LuLu is designed to be as simple as possible。certainly，This means that complex features may not be available，But it also means it's easier to use and has a smaller attack surface! Business Friendly Wondering what network events are detected? Or rules added by your users? LuLu provides a simple mechanism to subscribe to such events，and open、Store data like rules in an easily digestible way。 Network monitoring by design，LuLu only monitors outgoing network connections。Apple's built-in firewall does a great job of blocking unauthorized incoming connections。 Rules Currently，LuLu only supports "process level" rules，This means that the process (or application) is either allowed to connect to the network，or be banned。As is the case with other firewalls，This also means that if malicious code abuses legitimate (allowed) processes to perform network operations，this will be allowed。 single user currently，LuLu can only be installed for a single user。A future version may allow multiple users to install it on the same system。 DEFENSE YOURSELF What Legitimate Attackers/Security Experts Know，Any security tool that is specifically targeted，can be easily bypassed - even if the tool uses advanced self-defense mechanisms。This self-defense mechanism is often complex to implement，It's almost always in vain in the end。therefore，LuLu has (currently) few self-defense mechanisms implemented by design。For example，An attacker can enumerate all running processes to find the LuLu component responsible for displaying alerts and terminate it
