April 2018

We are happy to announce the release of Brainsight 2.3.10.

Before proceeding with this update, please read the following important information.

Minimum requirements:

• Mac OS X 10.9 Mavericks or later is required. For a free update, visit <https://www.apple.com/macos/how-to-upgrade/>. Contact us if you need to upgrade your Mac hardware.
• This version of Brainsight was tested against OS X 10.11.6 (El Capitan), 10.12.6 (Sierra), and 10.13.4 (High Sierra).
• We will not be supporting 10.9 and 10.10 for much longer, and no longer test them; if you still use either, please upgrade.

Special note:

• On macOS 10.13 High Sierra, if your Polaris is not detected, go to Apple Menu > System Preferences > Security&Privacy > General and look for an “Allow” button. See: <https://www.rogue-research.com/2018/04/polaris-on-macos-10-13-high-sierra/>.

Changes since version 2.3.9:

• The Session > Electrodes step is now shown for all TMS users, previously it was only shown if your serial number enabled the feature, but since so many of our TMS users use EEG also, we decided to enable it for everyone.
• The Session > Electrodes step can now be populated from a Cap Layout; similarly, a Cap Layout can now be created from the contents of the Session > Electrodes step.
• Assembly Lists can now be exported to the Brainsight .txt file format.
• Session subject registration matrices can now be exported from the Review window into a Brainsight .txt file.
• Shift-clicking electrodes in 3D views now allows selecting/unselecting multiple ones.
• Completely fixed a bug where scrolling through 2D slices with the mouse wheel would sometimes incorrectly show blank slices.
• Fixed a bug where the AC-PC-Box atlas space window would fail to redraw after pressing the Update button.
• Fixed performance and responsiveness problems when using the Axilum Robotics TMS-Robot.
• Improved performance working with large amounts of NIRS data: the waveform views should no longer fall behind data acquisition, though they may draw more slowly to keep up.
• Improved performance of live EMG waveform views, they now draw more smoothly.
• Fixed miscellaneous bugs.

Download:

• Brainsight 2.3.10 can be downloaded from our website here: <https://www.rogue-research.com/downloads>
• You’ll need your serial number, which you can get from Brainsight itself from the Brainsight menu > ‘Enter/View Serial Number’.

Feedback:

• Please report any and all bugs, feedback, suggestions, etc. to <support@rogue-research.com> or by phone at +1-866-984-3888 (Canada & USA) or +1-514-284-3888.

Thank you,

If you are using macOS 10.13 High Sierra through macOS 10.15 Catalina (inclusive) and Brainsight does not recognise your Polaris camera, please check the following things:

• open the Polaris Configuration window
• does the ‘Polaris Status’ show ‘No serial ports found’? (Not some other message.)

If so, it could be that you did not grant access to the FTDI kernel extension (kext). Starting in macOS 10.13 High Sierra, Apple made a change that requires users to grant a one-time permission to kernel extensions. If you upgraded your Mac from 10.12 or earlier, and were successfully using your Polaris previously, permission should be automatically grandfathered. If you are using macOS 11 Big Sur or newer, the FTDI driver is now built-in to macOS, and none of this applies.

The prompt for permission looks like this:

After this message appears, you have only 30 minutes to visit Security Preferences and approve.  Look for something like below:

If you don’t do this before the 30 minutes elapses, the easiest way to be prompted again is as follows:

• Open Terminal.app (not Console.app) to get a text prompt.
• Enter the command “sudo kextload /Library/Extensions/FTDIUSBSerialDriver.kext”, then enter the computer password at the prompt.
• From the Apple menu, open “System Preferences”, select “Security & Privacy”, then click “General”.
• Near the bottom you should see an “Allow” button, click it.
• Reboot the computer.

Fortunately, you need only grant permission once, and never again.
