> Shift key goes solo

Mac|Life - - ASK -

Since up­dat­ing to macOS 10.12.6, the Shift key on my Ap­ple wire­less key­board mis­be­haves with other mod­i­fier keys in Adobe apps. For ex­am­ple, hold­ing Opt and Shift while try­ing to draw a square from the cen­ter out in Pho­to­shop be­haves as if only one key is be­ing held, not both. This ap­plies to both of my key­boards, wire­less or ca­bled. What’s wrong?

If the rest of the Sierra up­date went fine, and you have no other glitches, this prob­a­bly re­sults from a driver or other ex­ten­sion, and has been re­ported with Wa­com graph­ics tablets.

A good test would be to dis­able third-party ex­ten­sions by start­ing your Mac in safe mode – see the end of this sec­tion for more in­for­ma­tion and full in­struc­tions on Ap­ple’s site – but that may make it im­pos­si­ble to use those apps, too. If you can use the apps in safe mode, test to see if the prob­lem oc­curs there. If it dis­ap­pears, in­ves­ti­gate re­cently in­stalled driv­ers.

If nec­es­sary, down­load ear­lier and later ver­sions of the driver, and see whether ei­ther makes any dif­fer­ence. You may find that the pre­vi­ous ver­sion does the trick. If you’re think­ing of up­grad­ing to macOS High Sierra, head to Wa­com’s driver down­load page ( bit.ly/ wa­com drv) for the lat­est up­dates.
