 ### 说明
-* 10月26号更新，百度云盘已经服务端限速，单文件最高200KB/S。
-* 6月21号更新，此补丁依旧适用于最新版。再次声明，此补丁没有加速功能。
-* 免责声明：本项目旨在学习macOS 逆向的一点实践，不可使用于商业和个人其他意图。若使用不当，均由个人承担。
-* 包含功能：百度网盘 SVIP破解和速度限制破解。
-* 若使用中遇到遇到问题， **Issue me！**
-* **破解完成后会提示让你输入密码，访问钥匙串权限。如果不想输入请执行"sudo chown -R $(whoami) 百度网盘路径"。[issues4](https://github.com/CodeTips/BaiduNetdiskPlugin-macOS/issues/4)。如果觉得不安全，请看源码。不懂的，我也不多做解释了。[issues15](https://github.com/CodeTips/BaiduNetdiskPlugin-macOS/issues/15)**
-* **此补丁只是破解了速度限制，并没有提速功能。如果安装完成后，速度没有变化，请搭配热度资源一块下载试试。**
-* **频繁使用可能导致账号或者IP被官方限制，如果出现之前能用，限制不管用了，请换账号试试。**
-* **上一条是我猜的，因为至今我的一直是可以用的。**
+* **20191118更新，去掉自动检查更新功能。由于个人精力和能力有限，此项目不再更新支持新版网盘。如使用，请下载2.2.2版本 [官方下载地址][1]。**
+
+* **连续下载10G数据后，会被限制速度到单文件20kb。所以，这个补丁偶尔用用就行，别一直用。**
+
+* **免责声明：本项目旨在学习macOS 逆向的一点实践，不可使用于商业和个人其他意图。若使用不当，均由个人承担。**
+
+* **本项目只用于学习和交流，有能力的请购买官方VIP服务。**
+
+* **包含功能：本地SVIP图标显示，去除本地下载速度限制（服务端已添加限制单文件200kb左右），去除本地极速下载试用时长限制，倒计时永久显示8秒（服务的token大概3分钟过期。意思就是虽然不倒计时，但是3分钟后速度还是会降下来）。**
+
+* **破解完成后，下载速度还是没有变化，可能是资源热度问题，或者是你已经进入百度网盘黑名单。**
+
+* **此项目不再更新，有问题请Issue中找答案，或者添加我微信（博客关于有二维码），很高兴能帮到你。**
+
+* **不会用的伸手狗请滚粗，别出问题后在这里乱咬人。**
