Iphones are supported by Capture One 10 as remote control but it is also possible to work with any Android web browser without remote login to your Mac. Set a custom keyboard first with ⌘R as camera trigger.
Then copy the following script to your webroot.
<?php exec('osascript -e \'tell application \"Capture One 10\" to keystroke \"R\" using {command down}'); ?> <a href="javascript:location.reload(true)"><button type="button">click</button></a>
after running in the terminal
sudo apachectl stop sudo nano /etc/apache2/httpd.conf # edit user to yourname and group to staff sudo apachectl start
