Prison break is required, and the system equipment is incompatible, so it cannot be installed.

Prison break is risky and needs to be careful. Apple's mobile phone system can easily maintain a good machine environment because it will automatically kill the process. After jailbreaking, you can experience more customized functions, but most people don't recommend jailbreaking, except those who like to pursue other development functions, but now many people use tools such as platform jailbreaking, PP assistant and ITURN to jailbreak with computers, but now many people rarely use computers. The computer has basically become a decoration. So now many people are studying to install software with mobile phone signature. At present, the mature Goose-Pig Sign directly contains the certificate that Apple needs after downloading, and can directly install some software to realize the jailbreak function on the mobile phone. It is also a good development. Solved a lot of troubles of computer jailbreaking. I used to escape from prison by computer, but it was very troublesome to escape again after every shutdown. Don't bother now, you can do it anytime and anywhere.
