El Capitan Bluetooth Keyboard Not Working

I have a mid 2009 Mackbook Pro that now has 10.11.4 El Capitan on it and this keyboard paired right up with it within seconds. I use this for closed display mode along with my 24" Viewsonic Monitor. It's a great little keyboard!

Very fast, no problem with Mac OS El Capitan, LightScribe ability.

I bought this on amazon for my Mac computer running El Capitan. It worked flawlessly. Much better than expected. NOTE: If you already have an older bluetooth adapter inside your Mac, be sure to disconnect it so macOS only sees the StarTech adapter and it will work like a charm.

I use it for my Mac. I had to work at it to get FileVault to work with it on El Capitan - you need to reformat (no problem) and then partition, for which you need to go to the command line Disk Utility now. Not hard, just that Apple seems to want to dumb down the graphical Disk Utility. If you don't care about that, it works straight out of the box.

Contrary to other posted comments, this device does work with El Capitan. I have two that are on two different computers (an iMac and a MacBook Pro) that receive daily use. About to purchase a third for a relative to use on a Mac Mini. I've deployed these on several Windows systems too. Absolutely 100% reliable and works without a hitch on both Mac OS X and Windows.

With the update of El Capitan on my 2012 Mac Pro, I discovered that my AJA Kona hardware would not work any more. And it had been dragging for quite some time with Premiere CC so it was time to upgrade. I read the reviews on this BM card and was concerned that it might not work correctly. I installed the card and software. I did notice the fan noise on the card on the first reboot until the machine prompted me to update the firmware. That update ran and the car operates silently now. I have the HDMI attached to my Panasonic LH2170P monitor, the S/DPIF audio connected to my Flying Cow converter and I am noticing no lag with Premiere Pro. Amazing inexpensive upgrade - wish I had done it sooner!

It works great. I am using the Apple Thunderbolt 2 to 3 adapter. Will not work that way running El Capitan. It is working flawlessly for me running Mojave.

My Clickfree drive didn't make it past the El Capitan OS X upgrade. Badly in need of a back up drive for my MacBookPro I purchased WD's 3TB My Passport USB 3.0 drive. (Yes, it is backward compatible to USB 2.0) What a pleasure it is to purchase a technology product that works perfectly and exactly as advertised. Initialize Time Machine, select either a back up schedule or not and then initiate a back up and this device backs up your entire hard drive.

Gives all the buttons I need. And I don't look like a weirdo with a full bluetooth keyboard when working in a coffee shop.

Read the fine print. This uses Bluetooth LE, and that requires an iPad3 or better. After wondering why it didn't work with either iPad2 here, I found that tidbit (which I had missed) in the fine print, hemmed, hawed, and opted to upgrade the iPad side of the system. It is a quality product, which on the one hand seems quite pricey for what is effectively a 2 button bluetooth keyboard, but on the other hand is much better made than whatever I might kludge up from a cheaper bluetooth keyboard with many more keys. The keys are lit, soft, and silent, and the device is considerably more affordable than some others in its niche - and with the keys on top, not over the edge, it works fine on carpets (some reviews indicate that is a weakness of some competing devices.) For hands-free page turning it really is ideal. Intended for foot operation, it is a bit larger than you'd expect from the pictures.
