    Requires an undocumented step to use with Mac Catalina - UPDATED WITH INFO RE: Mac OS16, Big Sur

    Requires an undocumented step to use with Mac Catalina - UPDATED WITH INFO RE: Mac OS16, Big Sur
    I've only had this a few days and I'm writing this review just in case you're running Mac Catalina, because I had a hard time figuring out the installation process. I eventually succeeded but not thanks to the instructions on the Edimax instructions or their website. If you are running Catalina you will definitely have to download the driver from their website (don't bother with the accompanying little cdrom). If your wifi card is working, you'll need to turn it off in System Preferences/Network; in my case, my wifi card had died, so I had nothing to turn off. You may well have to go to System Preferences/Security and Privacy, unlock that, then permit it to download from identified developers, before the installation will complete successfully. Now, here's a step that is NOT in the instructions: Once the driver installation eventually successfully finishes, and the mac restarts, look for a NEW LITTLE ICON up in the top menu bar. Find it? (see my photo -- icon looks different from this before wifi is turned on) Right-click on it and turn it on. If necessary, click on Open Wireless Utility to find your wifi network and sign on. So far, for me, this gizmo is working great -- but its installation instructions need re-writing, for Macs, at least. A last note: I read somewhere that if you update your macbook's operating system, this adapter won't work any longer, or at least until they update the driver. So be forewarned.NOTE, on 9/20 I contacted the manufacturer to ask if they would be supporting Mac OS16, Big Sur, when it comes out soon. I received this reply:"At this moment, we don't have schedule for the new driver of Mac 10.16 Big Sur. I am sorry about this. Usually we won't have new driver until a few months after the new Mac OS released. I personally think the new driver will be available at the beginning of year 2021 but I can not guarantee that.Please do not upgrade your Mac OS yet.Once we have new driver, we will post it on our web site. Thank you."

    5.0 out of 5 stars Worth the money!!
    Reviewed in the United States on May 10, 2017
    I received the adapter within 2 days after purchase, which was great. I plugged it into a USB 2 port on my old Dell M6400 laptop and then tried loading the driver from the mini-CD that comes with the adapter. My DVD player/recorder is just a slide in, without a pop-out caddy, so I couldn't use the mini-CD. Fortunately, there was a newer version of the driver on the EDIMAX website, so I downloaded and installed it, rebooted my laptop (required) and wah-lah it connected to my 802.11ac router with no problems.

    The speed was only 390 Mbps, which was a little disappointing since my Linksys External AC1200 adapter ran at 585-867 Mbps depending on my proximity to the router. I started moving the adapter to other USB ports, including a USB 3 port, but it still connected at 390 Mbps. Finally, I moved it to another USB 2 port, and suddenly I started getting a steady 520-585 Mbps (I'm not an electronics specialist, but the only difference I saw between the USB ports, is that this one was close to the internal antenna terminals).

    Anyway, considering the small size of the EDIMAX adapter, I am pleased with the performance (so far), and I can stop worrying about breaking off the adapter, as I almost did to the Linksys adapter which stuck out about around 3+ inches. BTW, the EDIMAX is faster than the internal Broadcom 802.11ac internal adapter I installed in the laptop 6 months ago, but if I can put in a better internal antenna in my laptop, I hope to eventually boost it up to 720 to 867 Mbps as I had with my previous laptop.

    Overall, this little adapter is more than I expected, especially for only $20. I would definitely recommend it to others looking to speed up older computers.
