Why is my mac crashing when downloading lockdown browser

If you experience errors while taking a test through the LockDown Browser, check your security settings in IE and the overall functionality of IE. IE should be reset to default security levels, and the exam should be tried again. If you attempt to use the browser to access additional course content, like lecture notes or worksheets, it may cause the program to encounter a problem and freeze or close.

This usually occurs when the content you are attempting to access is a Word, PowerPoint or Adobe Acrobat related file. If you need to view these files, please use a regular browser like Mozilla Firefox. If you are having problems installing LockDown Browser on a Windows system, we recommend the following additional steps:.

We strongly recommend using an Ethernet wired Internet connection with a speed of at least Kbps or higher while taking your exam in LockDown Browser. This is because the Canvas server is more bandwidth intensive especially during exams than normal Internet surfing. If you lose your Internet connection during the exam, it will lock up the browser and not allow you to save answers, move on to other questions, submit or exit the exam.

Ethernet connections are the most stable connection to the Canvas servers. If you have a router, plugging directly into it when taking exams will reduce the chances of connection interruptions.

We recommend completely uninstalling the software and doing a new installation while directly logged into the system as a local administrator with full rights see instructions above for full details. This occurs when there is a second level link being accessed from a primary level link. However, link blocking usually does not occur until the student enters a quiz and starts accessing links within a quiz. Usually, this comes from configuration issues with the underlying Internet Explorer browser components.

The LockDown Browser is programmed to detect when conflicting programs are still running and will request that you close these programs. Some programs like the Dell Dock and Google Toolbar run as a background process on your computer and will have to be shutdown before you can proceed in the LockDown Browser. You can usually turn these programs off through the task tray or, in the case of the Dell Dock, by right clicking on the application and clicking Exit.

In some rare instances, these programs running in the background can cause the LockDown Browser to lock up or stop responding. This is typically only available when taking the exam in a managed lab. Because many systems put the computer into suspension when pressing the power button once, it will likely be necessary for you to force a power down by holding down the power button for 5 to 20 seconds or longer.

Usually there is a small "chirp", "click" or "beep" as the local drive heads are locked into transport position and the display discharges during the power down. Keep holding down the power button until the computer completely turns off.

Ignore any messages that may appear on your screen during this process. We recommend the following steps to restore any default settings after a power down. A login is not necessary.
