Hi,
Yes, you can do something like this for example:
Sequence("block", "intro", randomize("experiment")) if (navigator.vendor.match(/apple/i)) newTrial( "block" , newText("<p>We're sorry, but this experiment is not compatible with your browser.</p>").print() , newText("<p>We encourage you to revisit this experiment \ using a desktop or laptop version of Chrome or Firefox if possible.</p>").print() , newText("<p>Thank you for your understanding.</p>").print() , newButton().wait() )
Note that filtering participants after recruiting them is against some recruitment platforms’ policy, such as Prolific’s (last time I checked)
