2、备份手机数据

  • 用 type-C 数据线将手机与电脑直连(注意不要接在拓展坞上)
  • 在 finder 中找到自己的 iphone,然后点击,可以看到备份操作
  • 直接点击备份

3、修改备份手机数据文件中的 info.plist 中的版本号

  • 打开 finder
  • 在 finder 界面,点击顶部菜单栏【前往】,【前往】菜单出来后,按住 option 键,可以看到【前往】菜单栏中出现【资源库】,点击进入【资源库】
  • 在【资源库】中,找到 Application Support/MobileSync,此目录即手机备份文件目录
  • 根据最近修改时间找到最新一个备份目录,点击进入,然后往下拉,找到 info.plist,双击打开文件,然后编辑,搜索 16.2 关键字即可,修改为 15.6,然后保存

详细步骤参考:https://www.iphonetricks.org/how-to-tweak-ios-16-backup-to-restore-ios-15/

4、还原系统

  • 在 finder 中,点击自己的 iphone
  • 按住 option 键,点击还原系统,在弹出的文件选择框中,选择下载好的 ios 15.6 的 ipsw 文件,耐心等待,这个时候就开始擦除手机系统,并恢复为 15.6 的版本,弹出的提示直接点确认即可
  • 耐心等待,知道系统版本恢复完成

5、恢复备份数据

  • 在完成第4步后,在 finder 中找到自己的 iphone 并点击,会显示正在激活
  • 待激活后,会显示恢复数据,并默认选中了备份文件(如果你的电脑只有一个备份,如果有多个,则选中最新一次的备份文件)
  • 此时手机界面显示 Restore in Progress,请耐心等待,直到恢复完成
