    USB Keyboard Compatibility Issues with MacBook Pro
    I am running a 2015 MacBook Pro with macOS High Sierra, fully updated. I am trying to use an external, wired keyboard. have been using an external PC keyboard with no issues. I just switched to a model A1048 for the Mac (just cleaned with all the keys taken off and put back on) that I had laying around and am experiencing the following issues:

    1. Unless I time plugging the keyboard in at just the right time during startup, the computer acts really strange. For example, if I click on any open app that is minimized it will only maximize via the finder window which pops up automatically if I click on the app.

    2. If I am in a Microsoft Word document and try to use the external keyboard, random windows open when I click various keys. This is only if I time plugging in the USB keyboard incorrectly. I cannot just plug it in after the laptop has been on.

    3. If I time the plugin of the keyboard just right, everything works beautifully except for the spacebar key which I think is an issue that happened while cleaning it.

    Any advice would be greatly appreciated.

    Have you tried any other USB keyboards to see if it is the MB Pro or the keyboard? This could be a keyboard issue. You are also using a Windows keyboard which could be causing compatibility issues. I know others who have seemed to have success using Windows keyboards but I have never tried one.

    Recommend using Onyx to clean your Mac.

    Is the keyboard connected directly to the MBP, or through a hub?

    Have you tried either of these;

    Please backup. Everything has a life cycle, unexpected and warning free. Nothing will last as long as you want it to.
