El Capitan and Microsoft Mouse (IntelliPoint) Not Working

Anonymous

After installing the El Capitan GM, the forward/back buttons (side buttons, 4 & 5) on my Microsoft Wireless Mouse 5000 are only registering as left mouse buttons. The most recent driver, Microsoft Mouse 8.2 is installed and shows up in the System Preferences, but appears to not be functioning. MicrosoftMouseHelper is in the login items. Suggestions?

    I'm so grateful I found this post and thread -- in my case, because with El Capitan my Intellitype Keyboard 4000 has also lost all its HotKeys...now I understand why, because I assume it's the same driver issue for the keyboard:

    "Intellitype software doesn't work on El Capitan because of the System Integration Protection feature.

    I disabled rootless through the recovery partition using the csrutil command in the Terminal window. Only then I was able to run Intellitype and Intellimouse apps.

    Apple strongly recommends to leave rootless enabled."

    I'm not going to disable SIP to get those hotkeys back, and I'll keep using my Intellitype because it's the most comfortable, ergonomic keyboard I've ever used, but I sure hope that MS does a quick fix on this.  I miss how fast I could do things with the press of a key with those Hotkeys!

    The first way *may* have worked, but I tried the second way listed above, and it worked but only after I unplugged the mouse from the USB port and plugged it directly into the MacBook. Once it saw the Mouse (1 sec) I unplugged it and got the same graphic showing "no mouse". I plugged it back into the usb port where it has sat for years, and it showed right up.

    So anyone with this issue, try Matt's steps from the Oct 1 post, and only try the second option later. And either way way make sure the mouse in question is plugged directly into the computer for the purposes of detection.

    For those of you this didn't work for, maybe try this Terminal command?

    csrutil disable

    If it doesn't help, be sure to run this one afterward when you reboot again:

    csrutil enable

    I just tried this step by step. I reinstalled Intellipoint, rebooted, but El Capitan still does not see the mouse:

    I have a Wheel Mouse Optical that has worked great on every Mac I've had, and OS X, for uncountable years :)
