Wacom drivers will not install

you're a genius, hooray <3 this works perfectly

The system language “trick” (if you can call it that, the installer bug was a blatantly unacceptable oversight on Wacom's part and instead of directing users on their forums how to work around the issue they should have fixed the ****** driver installer already!) stopped working on macOS Sierra 10.12.0. I used to use this method before, but it no longer works… Even more frustratingly, I know for a fact that the drivers worked on the Public Beta, yet, the Wacom preference pane was still moved to the incompatible preference panes folder and I can't, for the life of me, install them on my iMac after a clean install.

I am seriously considering of doing a video of myself setting fire to my Bamboo Create and posting it on YouTube.

Actually, I have some god news (sort of), for a change…

I was about to try reinstalling the driver, so I thought of cleaning my system of all its remnants by using the Wacom Utility instead of scouring my hard drive for Wacom support files. I first removed my preferences and, I don't really know why (whether I had the Wacom preference pane open or just thought of giving it a try), my Wacom driver came to life!

I didn't have the tablet connected (I was making sure that it did work on my MacBook Pro, and it did work after reinstalling the purportedly incompatible preference pane), but I got the familiar (and welcoming) message that, duh, I didn't have any supported device connected, instead of the dreaded driver error message. Lo and behold, I reconnected it to my iMac and it worked “fine” as well.

And I only say “fine”, because everything works except 4-finger gestures, those are utterly broken (I don't know whether it has anything to do with the “softer” gestures in Sierra, which detect differences in speed and allow you to revert them midway, much like the Spaces switching one already did, but I suspect it does), they just fail and kind of default to their 3-finger counterparts.

As of this date, the driver for the Wacom Bamboo CTH-661 (medium size with "Pen & Touch" function) and other similar generation tablets stops working upon an upgrade to macOS Sierra. Maineyehc gave me hope. As of this moment, function is restored and my tablet is working just fine under the current macOS! Here's what I did. Thanks, Maineyehc.

1. Go to top level of your system, ~/Macintosh HD

2. If you had the Wacom drivers installed previously and received a notice that they were incompatible with macOS Sierra, they were moved over to ~/Macinstosh HD/Incompatible Software. Open this folder.

3. Disconnect your tablet.

4. Double click on PenTablet.prefPane, ignore complaints.

4. Just do it.

5. Restart your system.

6. Plug your tablet back in.

As of this moment, I'm going to leave PenTablet.prefPane in the Incompatible Software folder. I'd rather have it working in here than move it and get grief and a dead device. If anyone knows a reason why I should move it and whether it continues to work, let me know.

The Wacom icon has returned to System Preferences but it gives an error when I click on it.

This method has restored my tablet to the function I had previously: edge-to-edge non-mouse-like tracing and right-click on the pen. Touch still works (not all devices had touch). The device still tracks in the opposite direction as my (newer) Apple tackpads. Easy fix to restore a tablet I was in no mood to replace. Again, thanks Maineyehc for the hope and guidance.

rb.qd, though I wouldn't mind in the least seeing Wacom losing another customer to Huion or, better yet, to Apple itself (those iPad Pros + AstroPad are looking sweeter and sweeter every day, and the rumoured iPad Mini Pro will be an even more interesting and affordable multi-function proposition 😉 ), I am also adamantly against waste and wish you or other users no more added expenses just to get your job done. I am very happy for having been of service to you!

Well, as for the old, supposedly incompatible PrefPane, I think you can safely move it out of the Incompatible Software folder and into /Library/PreferencePanes… Actually, I've been using that part of the trick for a while already with no issues whatsoever; I don't recall whether it was under Yosemite or El Capitan, but I'm pretty sure that after one of those updates the OS pulled that one on me and I wouldn't have any of it… To my surprise, it did work back then, too. I guess Apple was and is just being too conservative about driver compatibility (and Wacom just being too lazy to bump its version a notch just to keep OS X/macOS happy about it). Oh well…

Found this on stack exchage. It worked for me 8)

Apparently "On 10/12/2016, Wacom Driver 5.3.7-6, which is certified for macOs 10.9x-10.12x" was released.
