I’m near people who use presentation remotes but don’t use one myself so I don’t have a specific recommendation. If this is your first remote, maybe don’t think too much about it and buy a cheap (less than $35 USD) “starter remote” that has 4+ stars on Amazon based on a decent quantity of reviews. Through use you can learn what failings/limitations are a problem for you and which aren’t.
All remotes basically map particular keyboards keys to a few buttons, the left and right arrows being the most essential, they work with basically every application including things like Finder’s CoverFlow. Generally remotes have a “start” button but it may not work in all applications (in may even only work in PowerPoint, not Keynote or Preview). To me, a remote doesn’t need to start because I have to be at the computer to open the file anyway. If you know you’ll regularly have presentations that include video, a remote that can control volume (at the OS level) could be useful but it may be tricky to find one that will also play/pause embedded videos (BTW, the Apple media keys can control YouTube in Safari); at the same time, if videos are linked to instead of embedded, you’ll probably have to go to the computer to click the link if you’re not using a remote with cursor control like the Logitech Spotlight or Gyration Air Mouse. “Image mute” (maps the ‘b’ key, works in PowerPoint & Keynote, not Preview) can be useful when you want to pause and not have screen be a distraction).
Bluetooth is convenient with the Mac but the cheapest remotes seem to require a USB receiver. Bluetooth is also less convenient and a USB receiver when sharing the remote with others, especially others with Windows. I don’t see any remotes that use USB-C so if you have an MBP from the past couple of years, you’ll need an adapter. This is also true of using USB to recharge, the remote’s port is probably micro USB and the bundled cable will be USB type A on the other end. Replaceable batteries should last a long time so long as a remote doesn’t have a problem with accidentally being turned on in a bag (especially turning on a laser); a different Logitech remote lists over 1,000 hours of presenting time and 20 hours of (red) laser time.
Green lasers are brighter and easier to see, especially over longer distances, but use more power and are more expensive than remotes with red ones.
