Many people have just switched from the familiar Windows to the unfamiliar Mac, and it is inevitable that they will encounter some difficulties during use. Some friends encountered such a problem. They downloaded software online. The downloaded software installation package was a compressed RAR package. After decompressing it, they found that the software could not be opened, and the system popped up "The application "XXX" cannot be opened." hint. What should I do if I can’t use the software I downloaded so hard? Don't worry, this is because after the software is compressed and decompressed, the permissions of the executable file are erased, so it cannot be opened. Let’s take the software AKVIS ArtWork as an example to tell you how to solve this problem.
Specific operation methods
1. Right-click the software and select "Show Package Contents".
2. Open "Contents - MacOS" in turn and find the "ArtWork_std (or Plugin Installer)" file. You will find that this is a file of unknown type. In fact, the file was originally an executable file. Due to the loss of permissions, it became a file of unknown type, causing the software to be unable to open it.
3. Open the terminal, enter "chmod +x", note that there is a space between "chmod" and "+x", then space again, drag the "ArtWork_std (or Plugin Installer)" file into the terminal, and press Enter.
4. After pressing Enter, you will find that the unknown type of file has changed back to the black icon of the executable file.
5. Open the software and it can be used normally~
The above is the solution that the editor has compiled for you when encountering the situation of "the application "XXX" cannot be opened". You only need to enter a command in the terminal to solve the problem. Isn't it very simple? In this situation, friends who are at a loss because the software cannot be used, quickly follow the editor's method and give it a try!
