※ 引述《snoopydoggy (Snoopy)》之铭言：
: 刚才以 clean install 的方式灌 Mojave 后
: 在灌给 Kensington Orbit 用的 Trackballworks 到系统设定面板时
: 安装完自动重新开机以后
: 系统偏好设定最下面像之前一样有出现icon
: 但点进去以后写说
: 请于系统偏好设定－安全性与隐私－一般－按一下允许按钮
: 问题是进去一般里面并没有任何允许的按钮
: 重灌了好几次都这样
: 请问该如何处理呢？
今天收到客服回信，新版的 TrackballWorks 1.5.0 已经释出
https://www.kensington.com/software/trackballworks-customization-software/
官方客服建议的更新步骤如下：
1. Go to System Preferences > right click on TrackballWorks > remove
2. Open Finder in the computer
3. Click on “Go” in the menu bar on the top
4. Select “Go to Folder” and search for “~/Library” and return
5. Open “preferences” folder and please look for
“com.kensington.trackballworks.settings.plist” and delete it
6. Restart the computer
7. Follow the below link to download the latest TrackballWorks software file
https://www.kensington.com/siteassets/software-support/trackballworks-1.5.0.dmg
8. Install the software from the downloaded file
9. Restart the computer
10. Go to System Preferences > Security and Privacy > General
11. Click on "Allow" near "Some system software is blocked from loading"
12. Go to System Preferences > Security and Privacy > Privacy > Accessibility > check TrackballWorks Helper
13. Unplug the Trackball and plug it back in
14. Open TrackballWorks and check the functionality
基本上我没遇到第 10 跟第 11 点，安装完重开机后 TrackballWorks 就可以用了
给有需要的人参考 :)
