Huge shoutout to @damienbarrett on the Mac Admins Slack Team for the fix. I’m just documenting it here, in case anyone else runs into this problem and is searching for the solution.
Problem
You launch up Wabbit Emu and try to run your TI-## calculator ROM, and the onscreen buttons don’t match up with what’s actually happening on the emulated screen. For example, you might click the Clear button and see the number 1 appear instead.
Solution
First, quit out of Wabbit Emu completely (Cmd-Q).
Right-click on WabbitEmu.app and select Get Info.
Scroll down a bit until you see four checkbox options. Check (or tick) the Open in Low Resolution box, and then close that window.
Now when you open up WabbitEmu, the appropriate onscreen buttons should work.
Scripting it
If you want to script this change, check out pudquick’s Python script to set LSHighResolutionModeIsMagnified. You may have to modify it, of course, since it uses TextEdit as an example app:
lowres_app_id = u’org.revsoft.WabbitEmu‘
Just keep in mind that after the script runs, the user will have to log out and log back in again for the change to take effect.

Thank you! Thank you! My good old Wabbitemu is working again. I upgraded to MacOS Catalina, and couldn’t make my onscreen calculator do anything. This totally fixed it. Such a useful tool for teaching my tutoring students how to use the TI-84. Thanks again.
Thank you very much.
Adding my voice to the thanks! I was getting really frustrated with Big Sur and this did the trick.
Any updates on the new macbook update? My calculator used to work but now it’s doing the 1’s thing as described in here. When I right click to select low resolution box, it’s no longer an option. All that’s available to click is “prevent app nap” and “locked”.
I have a new iMac and it does not give me the “low resolution” option. Only “prevent app nap” and “locked”. Can anyone help?
